4.10.4  Examination of Income

4.10.4.1  (06-01-2004)
Overview

  1. The purpose of this section is to provide guidance for the examination of income. It includes the minimum income probe requirements for all types of returns, in-depth examination techniques, and formal indirect methods. See IRM 4.10.4.3.5 for instructions regarding income probes for nonfilers and delinquently filed returns.
  2. An examination of income is conducted to determine whether taxable income has been accurately reported on the tax return. The steps taken in an examination are dependent on the facts and circumstances, and therefore, the audit strategy for completing the examination of income must remain dynamic. Consideration should be given to tax return information, responses to interview questions, the taxpayer’s books and records, and other financial information when completing an examination of income. As new information becomes available, the audit plan should be adjusted accordingly; examiners should use their judgment when determining the depth of the examination of income.
  3. It is advisable to include a statement on the initial IDR indicating that the examiner may request additional records as the examination progresses. This will help prevent any potential misunderstanding about the scope and depth of the examination of income.
  4. Examinations of income for all business tax returns should incorporate industry-based audit techniques. Audit technique guides are included on the CCH disk provided to examiners. The audit technique guides and other industry-based information are available at the following sites.
    1. SBSE's Technical Guidance at http://sbse.web.irs.gov/TG/TGIndustryIssues.htm
    2. LMSB's Pre-filing & Technical Guidance - Industry Guides at http://lmsb.irs.gov/hq/pftg/guides.asp
    3. IRS's web site at http://www.irs.gov. Use the menu to select " Businesses" , and then "More Topics" , under Related Topics. The first heading on the list is "Audit Technique Guides " , which will provide a listing of guides in alphabetical order.

     

4.10.4.1.1  (06-01-2004)
Scope of Section

  1. IRM 4.10.4 applies to all examinations conducted by interview.
  2. IRM 4.10.4 does not apply to correspondence examinations.

4.10.4.2  (06-01-2004)
Definitions

  1. The following definitions are provided to clarify terms used within this IRM section. An understanding of these definitions is helpful to complete the Examination of Income.

4.10.4.2.1  (06-01-2004)
"Nonbusiness" Returns

  1. Individual returns with activity codes 530–534, with no attached business schedule(s); i.e., no Schedule C or Schedule F.
  2. For Office Audit, individual returns which have an attached business schedule(s) Schedule C or Schedule F) and Gross Receipts is NOT a classified issue.

4.10.4.2.2  (06-01-2004)
"Business" Returns

  1. All types of returns other than nonbusiness returns described in 4.10.4.2.1, above.
  2. For Office Audit, individual returns which have an attached business schedule(s) Schedule C or Schedule F and Gross Receipts is a classified issue.

4.10.4.2.3  (06-01-2004)
Gross Receipts or Gross Income

  1. The term "Gross Receipts" or "Gross Income" means the taxpayer's total or gross taxable receipts during the year from all sources. Gross Receipts is not reduced by returned sales, allowances, cost of goods sold, basis, or expenses. Gross Receipts includes, but is not limited to the following:
    1. gross sales of a trade or business;
    2. gross fees and commissions;
    3. gross wages, salaries, tips, and gratuities;
    4. gross dividends, interest, rents, royalties, pensions, and annuities;
    5. gross income from estates, trusts, and partnerships;
    6. gross proceeds from the sale of assets; and
    7. gross farm income.

     

  2. Gross receipts does not include nontaxable income; e.g., gifts, loans, etc.

4.10.4.2.4  (06-01-2004)
Gross Business Receipts

  1. The term Gross Business Receipts means the gross receipts derived from a trade, business, farm, or profession. The distinction between " Gross Receipts" and "Gross Business Receipts" is important when examining nonbusiness returns or business returns which also include nonbusiness income.

4.10.4.2.5  (06-01-2004)
Cash-on-Hand

  1. Generally, Cash-on-Hand is currency (not balances in bank accounts) associated with routine business practices and/or the need to complete cash transactions with customers.

4.10.4.2.6  (06-01-2004)
Accumulated Funds

  1. Accumulated Funds is currency accumulated by the taxpayer, but not associated with routine business practices and/or transactions with customers. The funds may have been taxed in prior years, originate from nontaxable sources, or may represent taxable income in the year under audit.

4.10.4.2.7  (06-01-2004)
Specific Item Method

  1. The specific item method involves the use of direct evidence to determine the tax liability based on omitted income, overstated expenses, or both. Direct evidence is evidence from which only one logical conclusion can be reached.
  2. Direct documentary evidence is generally regarded as having the greatest value and, when possible, examiners should ask to see the original documents when there is reason to believe they exist. Documentary evidence should not be solely relied upon to the exclusion of facts established through oral testimony or other techniques, such as a tour of the business site.
  3. The specific item method is appropriate when the taxpayer maintains books and records, adjustments are due to technical issues (such as timing or character of funds), or the potential sources of unreported income are limited (such as an insurance agent who underwrites for several companies).
  4. The specific item method is not useful if the taxpayer's gross receipts are generated from numerous sources or in small amounts, such as a grocery store.
  5. See IRM 4.10.7.3 for complete discussion.

4.10.4.2.8  (06-01-2004)
Indirect Method

  1. The indirect method involves the use of circumstantial evidence to prove omitted income, overstated expenses, or both. Circumstantial evidence is evidence from which more than one logical conclusion can be reached. To support adjustments for additional taxable income, both the credibility of the evidence and the reasonableness of the conclusion must be evaluated before the determination of tax liability is made.
  2. Analytical reviews and testing of the taxpayer's books and records conducted during the minimum income probes may result in the identification of additional taxable income. The Financial Status Analysis and Bank Account Analysis are not prohibited by IRC section 7602(e), Limitation on the Use of Financial Status Audit Techniques, simply because an adjustment to taxable income supported by indirect (circumstantial) evidence may be the result. Ultimately, the completion of the minimum income probes may result in the determination of additional tax liability using a formal indirect method.
  3. Example : The minimum income probes for an individual business return includes a Bank Account Analysis (see IRM 4.10.4.3.3.6). There is an identifiable potential source of additional taxable income. The records used for the analysis are the bank account statements, which are prepared by a third party, and are credible evidence. The characterization of excess funds as additional taxable income is reasonable because deposits of nontaxable funds are identified and eliminated.
  4. See IRM 4.10.7.3 for complete discussion.

4.10.4.2.9  (06-01-2004)
Formal Indirect Method

  1. The formal indirect methods are audit techniques used to determine the amount of unreported income.
    1. Bank Deposit and Cash Expenditures Method (IRM 4.10.4.6.3)
    2. Source and Application of Funds Method (IRM 4.10.4.6.4)
    3. Percentage of Markup Method (IRM 4.10.4.6.5)
    4. Unit and Volume Method (IRM 4.10.4.6.6)
    5. Net Worth Method (IRM 4.10.4.6.7)

     

  2. The formal indirect methods are also known as Financial Status Audit Techniques. See IRM 4.10.4.6.1 for additional discussion. They are distinguishable from other audit techniques by the following characteristics:
    1. reliance on indirect evidence of income,
    2. in-depth analysis of actual costs that requires the extensive collection of detailed information using intrusive techniques, and
    3. subject to IRC section 7602(e), which states that "the Secretary shall not use financial status or economic reality examination techniques to determine the existence of unreported income of any taxpayer unless the Secretary has a reasonable indication that there is a likelihood of such unreported income."

     

  3. Formal indirect methods are appropriate when the taxpayer's books and records are missing, incomplete, or irregularities are identified; or the Financial Status Analysis (see IRM 4.10.4.3.3.1) indicates a material imbalance of cash flows after consideration of other adjustments identified during the examination. See IRM 4.10.4.6.2.

4.10.4.3  (06-01-2004)
Minimum Requirements For Examination of Income

  1. Examiners will consider Gross Income during the examination of all income tax returns. Certain minimum probes will be made regardless of the type of return filed by the taxpayer. The minimum income probes are fundamentally designed as a set of analytical tests intended to determine whether the taxpayer accurately reported income. If the taxpayer is underreporting income, the probes should result in the identification of at least some of the understatement.
    1. The minimum income probes vary depending upon the type of return (nonbusiness or business) and the method of the examination (Office Audit or Field Examination).
    2. The minimum income probes are not subject to IRC section 7602(e) governing the use of Financial Status Audit Techniques.

     

  2. Reported Gross Income will be considered regardless of whether the taxpayer maintains a double-entry set of books.
  3. When the amount of a Net Operating Loss deduction (NOLD) is material, it constitutes a large, unusual, or questionable item (LUQ) that should be addressed as part of the examination of income. See IRM 4.10.2.3.1 for complete LUQ discussion. Refer to Exhibit 4.10.4-6, Auditing Net Operating Loss Deductions (NOLD), for additional audit guidance. Additional factors specific to NOLDs, which should be considered, include:
    1. The NOLD was generated from the same business that gave rise to an adjustment for unreported income in the current year under examination.
    2. Materiality of the current year adjustment to income,
    3. Likelihood of erroneous reporting in prior years,
    4. Materiality of NOLD, and
    5. Prior audit activity.

     

4.10.4.3.1  (06-01-2004)
Exception to the Minimum Requirements

  1. Minimum income probes will be conducted during every examination unless the examination is a "limited scope" examination. See IRM 4.10.2.6.1.1, Limiting the Scope of an Examination, for detailed discussion. The scope of an examination of a return may be limited to one or two issues if the return does not appear to be worthy of examination for any other issues.
  2. Before limiting the scope of an audit of an individual business return, a preliminary Financial Status Analysis based on the tax return data and available data will be prepared as outlined in IRM 4.10.4.3.3.1(6)(a). If the analysis indicates a material imbalance, the excess expenditures are considered to be a potential understatement of taxable income which requires further development during the audit; i.e., the minimum income probes must be completed.
    1. Example 1 : a claim will be examined for a highly technical issue requiring factual development. The preliminary Financial Status Analysis indicated the taxpayer had sufficient funds for the expenditures identified on the return. The scope of the audit can be limited to the technical issue.
    2. Example 2 : A taxpayer filed a 1040X reflecting a significant increase in Schedule C expenses. The statute was open for the claim issue only. The taxpayer verified all the additional expenses during the audit. However, when the additional expenses were included in the preliminary Financial Status Analysis, there was a material imbalance. The scope of the audit should not be limited; the material imbalance should be resolved.

     

  3. Before limiting the scope of an audit of a related return, examiners should determine whether the related return warrants examination from a classification perspective; i.e., trace the transactions between the individual and related business entity, complete a Financial Status Analysis based on the related return as filed and internal sources of information (see Exhibit 4.10.4-2), and review the return for other potential issues. See IRM 4.10.5.4, Related Returns.
  4. The examination workpapers should state that the scope of the audit was limited and cite the reasons.

4.10.4.3.2  (06-01-2004)
Minimum Income Probes: "Nonbusiness" Returns

  1. The taxpayer should be interviewed. From the taxpayer's perspective, an interview with an Internal Revenue agent may be overwhelming. Therefore, initial interviews should be professional and not overbearing; the taxpayer should be afforded 100% credibility. Question the taxpayer concerning possible sources of income, other than those reported, and Accumulated Funds. This questioning and completion of Form 4700–A, Form 4700 Supplement, or comments on Form 4318, Examination Workpapers, will fulfill the minimum income probe requirement if there is no other information in the file indicating potential unreported income. See IRM 4.10.4.3.3.2, IRM 4.10.4.6.8.3 and Exhibit 4.10.4-1 for additional guidance on interviewing taxpayers.
  2. Internal Revenue Code section 7521(c) states that an examiner cannot require a taxpayer to accompany an authorized representative to an examination interview in the absence of an administrative summons. However, the taxpayer's voluntary presence can be requested through the representative as a means to expedite the examination process. Should an examiner find that a representative is shielding a taxpayer, an examiner can bypass the representative and deal directly with the taxpayer. See Exhibit 4.10.4-5, Bypassing Powers of Attorney.
  3. An analysis of all IRP information in the file should also be done to ensure there are no other business or investment activities not included on the tax return.
  4. Possible bartering income should be considered as part of the minimum income probes.
  5. A preliminary Financial Status Analysis will be completed for all nonbusiness returns which include a Schedule C, E, or F, regardless of whether Gross Receipts was classified as an audit issue. The analysis will be based on the tax return as filed, information included as part of the case building, and information available through internal sources. See IRM 4.10.4.3.3.1 for detailed explanation and instructions.
  6. With regards to IRC section 7602(e), which addresses the use of Financial Status Audit Techniques, examiners should not routinely ask for bank statements, cancelled checks or deposit slips to complete the examination of income on nonbusiness returns. Requests for documentation supporting specific issues can be made and may include cancelled checks. There may be situations in which there is a reasonable indication of unreported income in the pre-contact stage of the examination; i.e., a grossly imbalanced Financial Status Analysis or Forms 1099 for business income not included on the tax return. In such situations, the initial information document request (IDR) may include a request for personal banking records, including bank statements, cancelled checks, and deposit slips.
  7. Deviations from the minimum income probes must be approved by the Group Manager and documented in the case file.

4.10.4.3.3  (06-01-2004)
Minimum Income Probes: Individual "Business" Returns

  1. An examination of gross income on an individual business return will include the following audit techniques:
    1. A Financial Status Analysis to estimate whether reported income is sufficient to support the taxpayer's financial activities.
    2. An interview with the taxpayer (or representative) to gain an understanding of the taxpayer's financial history, identify sources of nontaxable funds, and establish the amount of currency the taxpayer has on hand. See Exhibit 4.10.4-1, Interview Questions Addressing Accumulated Funds.
    3. A tour of the business site to gain familiarity with the taxpayer's operations and internal controls, and identify potential sources of unreported income.
    4. An evaluation of internal controls to determine the reliability of the books and records, identify high risk issues, and determine the depth of the examination of income.
    5. Reconciliation of the income reported on the tax return to the taxpayer's books and records.
    6. An analysis of the taxpayer's personal and business bank accounts to evaluate the accuracy of gross receipts reported on the tax return.
    7. An analysis of business ratios to evaluate the reasonableness of the taxpayer's business operations and identify issues needing a more thorough examination.

     

  2. Deviations from the minimum income probes must be approved by the Group Manager and documented in the case file.

4.10.4.3.3.1  (06-01-2004)
Financial Status Analysis (Individual Business Return)

  1. A Financial Status Analysis is an analysis of the taxpayer's cash flows to estimate whether there are sufficient funds to cover the taxpayer's expenses. The analysis serves two purposes:
    1. determining the depth of the examination of income, and
    2. establishing that there is a reasonable likelihood of unreported income that justifies the use of a formal indirect method.

     

  2. The intent of the analysis is to determine whether there is a significant risk of a material misstatement of taxable income. Materiality is the significance or importance of an item in determining the correct tax liability and requires the examiner’s judgment regarding the return as a whole and the separate items that comprise the return. Among the factors which must be considered when determining whether the imbalance is material are:
    1. Comparative size of the imbalance;
    2. Absolute size of the imbalance;
    3. Results of multi-year analysis;
    4. Ratios and industry standards;
    5. Relationship between the size of the imbalance and the tax liability.

     

  3. The Financial Status Analysis should include consideration of all sources and expenditures of funds identified on the tax returns, information included as part of the case building and internal sources of information (see Exhibit 4.10.4–2, Internal Sources of Information), and reasonable estimates for other expenses known to exist, but for which the exact costs are not known. Personal living expenses can be estimated using Bureau of Labor Statistics information. The analysis should also be updated during the examination as additional information becomes available; i.e., nontaxable sources of funds or disallowed expenses.
  4. Example : As part of the pre-contact planning process, an examiner may perform internal research of resources such as Choice Point, Currency and Banking Retrieval System (CBRS), Information Document Retrieval System (IDRS), Corporate Files on Line (CFOL), and/or Midwest Automated Compliance System (MACS). Note: some of this information may be automatically included with case building.
  5. The Cash-T provides a quick and easy format for documenting and determining whether there is an indication of a potential understatement of taxable income. Enter sources of cash funds on the left side of the Cash-T and expenditures of cash funds on the right side. Total sources are compared with total expenditures.
  6. The completion of a Financial Status Analysis does not trigger the provisions of IRC section 7602(e), which states that "the Secretary shall not use financial status or economic reality examination techniques to determine the existence of unreported income of any taxpayer unless the Secretary has a reasonable indication that there is a likelihood of such unreported income" . A Financial Status Analysis is an analytical tool used to identify and estimate the materiality of cash flow imbalances. Financial Status Audit Techniques are the formal indirect methods used to make the actual determination of tax liability and are subject to the limitations of IRC section 7602(e). See IRM 4.10.4.6
  7. Steps for completing a Financial Status Analysis:
    1. Prepare a preliminary Cash-T based upon the tax return data and information in the case file; e.g., records of monetary transactions (CBRS). If the Cash-T indicates a material imbalance, the excess expenditures are considered to be a potential understatement of taxable income which requires further development during the audit.
    2. Use subsequent interviews and information gathering during the examination to update the Financial Status Analysis and resolve any imbalance. For example, when the profit margins are consistently low, but the taxpayer is able to continuously service substantial debt (mortgage), the examiner should make further inquiries.
    3. The analysis should be updated as audit adjustments are identified. The adjustment may be the result of unreported gross receipts, overstated expenses, or from a combination of these items.
    4. When completed, the Financial Status Analysis should indicate that either income is sufficient to support the taxpayer's financial activities or there is a significant imbalance indicating the potential for unreported income.

     

  8. An examiner may consider observing a taxpayer's residence when completing a Financial Status Analysis. However, observing a taxpayer's home should not be intrusive and generally should not include talking with the taxpayer's neighbors. Inspections of the inside of a taxpayer's home should be limited due to privacy issues and the intrusive nature. (Note: the purpose of inspecting the interior of a taxpayer's home includes determining the validity of a deduction for an office or business located in the residence.)
  9. Example: An examiner believes, based on the address on the tax return, that the taxpayer's home is located in a recently developed subdivision where the homes are selling for more the $300,000. The preliminary Financial Status Analysis indicates that the taxpayer could not support the purchase or maintenance of such a home based on the reported income. The examiner drives by the home and discovers that the taxpayer lives in a modest 40 year old home across the street from the new subdivision.
  10. The preliminary Financial Status Analysis and subsequent modifications will be made part of the examination workpapers.
  11. Financial Status "Audits" are cases where the Financial Status Analysis indicates that the taxpayer's sources of funds are not sufficient to support the taxpayer's financial activities, and the use of a formal indirect method can be justified. Note: the decision to use a formal indirect method should not be made until after completion of the minimum income probes.

4.10.4.3.3.2  (06-01-2004)
Initial Interview (Individual Business Return)

  1. The taxpayer should be interviewed. From the taxpayer's perspective, an interview with an Internal Revenue agent may be overwhelming. Therefore, initial interviews should be professional and not overbearing; the taxpayer should be afforded 100% credibility.
  2. Internal Revenue Code section 7521(c) states that an examiner cannot require a taxpayer to accompany an authorized representative to an examination interview in the absence of an administrative summons. However, the taxpayer's voluntary presence can be requested through the representative as a means to expedite the examination process. Should an examiner find that a representative has unreasonably delayed or hindered an examination, an examiner can bypass the representative and deal directly with the taxpayer. See Exhibit 4.10.4-5, Bypassing Powers of Attorney
  3. Question the taxpayer/representative concerning possible nontaxable sources of funds, gifts, loans, known errors/omissions on the return, and unreported sources of income. These questions should be addressed at the initial interview early in the examination. The information will be needed to reconcile the Financial Status Analysis, analyze the bank accounts, and reconcile the income reported on the tax return to the books and records. Also, the information will be critical should it later become necessary to use a formal indirect method to make the actual determination of tax liability.
    1. If loan proceeds are identified, request the loan application documents to verify the source and amount of the nontaxable funds. Bank loans are easily documented; however, loans or gifts from family members or other individuals pose a more difficult verification problem. The examiner should inquire as to why the amount provided was cash, when the amount was given, how it was given (one payment or multiple) and any provisions for repayment. Review the documentation for consistency with other evidence; i.e., cash flows, anticipated gross receipts, etc. Discrepancies should be resolved with the taxpayer's assistance.
    2. Nontaxable sources of funds can be eliminated by showing that the provider of the funds was incapable of generating the amounts stated by the taxpayer; i.e., the absence of any documentation reflecting the source of the funds and/or the absence of sources of funds available to the provider.
    3. Refer to IRM 4.10.7.3, Evaluating Evidence, for additional guidance.

     

  4. Affirmatively obtain the beginning and ending balances for cash-on-hand from the taxpayer or representative for the year(s) under examination. See IRM 4.10.4.6.8.3 for complete discussion and Exhibit 4.10.4-1 for interview questions. Generally, cash-on-hand is currency associated with normal business practices and the need to complete cash transactions with customers. If additional years are examined, be sure to determine and document the beginning and ending cash-on-hand for those years. This information will be needed to complete the reconciliation of income as reported on the tax return to the taxpayer's books and records and will be critical should it later become necessary to use a formal indirect method to make the actual determination of tax liability.
  5. Affirmatively determine the beginning and ending balances of accumulated funds for the year(s) under examination. Generally, accumulated funds is currency not associated with normal business practices. The funds may have been taxed in prior years, originate from nontaxable sources, or may represent taxable income in the year under audit. See IRM 4.10.4.6.8.3 for complete discussion and Exhibit 4.10.4-1 for interview questions.
  6. Ask the taxpayer for assistance to resolve a Financial Status Analysis indicating a material imbalance.
    1. Example : an examiner completes a pre-contact analysis of an individual taxpayer's return with a Schedule C. Based upon an analysis of the taxpayer's cash flows on the face of the return, the examiner believes the reported income is insufficient to support the taxpayer's expenses. The examiner may ask the taxpayer how the financial activities were supported, based on the income reported on the return.

     

  7. Ask the taxpayer to explain the accounting system, including:
    1. the normal flow of each type of transaction from its initiation to its inclusion in the financial statements, and
    2. the flow of funds into and out of the business.

     

  8. Question the taxpayer regarding business policies and practices for:
    1. product pricing and determining profit margins,
    2. accounting for Cost of Goods Sold, and
    3. accounting for spillage, breakage, and theft losses.

     

  9. IRC section 7521(b)(2) requires examiners to suspend interviews when taxpayers state that they wish to consult with a representative or otherwise seek advice. The taxpayer’s right of consultation will be strictly observed and interviews will be suspended and rescheduled accordingly. This provision does not apply to interviews initiated by administrative summons and will not be used to repeatedly delay or hinder the examination process.
  10. For Tax Compliance Officers and Tax Auditors: Completion of Forms 4700–A, Form 4700 Supplement, and Form 4700–B, Business Supplement, will assist the auditor in fulfilling the minimum income probe requirements.
  11. Refer to IRM 4.10.7.3.2, Oral Testimony, for complete discussion and documentation requirements.

4.10.4.3.3.3  (06-01-2004)
Tour of Business Sites (Individual Business Return)

  1. Conduct a tour of the business site. Generally, the principal location and any other locations acquired during the period under examination should be visited. The purpose of a tour is to:
    1. gain familiarity with the taxpayer’s business operation and internal controls,
    2. identify potential sources of unreported income, and
    3. confirm the existence of assets.

     

  2. This requirement applies to Field examinations only.
  3. The results of a tour and any observations and/or comments should be documented in the examination workpapers.
  4. See IRM 4.10.3.3 for complete discussion.

4.10.4.3.3.4  (06-01-2004)
Evaluation of Internal Controls (Individual Business Return)

  1. Evaluate the internal controls to gain an understanding of the taxpayer’s business operations and control features. The evaluation will help examiners set the scope and depth of the examination of income and determine the appropriate audit techniques.
  2. The evaluation should not be limited to a consideration of the segregation of duties. See IRM 4.10.3.4 for complete discussion. Examiners should:
    1. Determine the reliability of the books and records, regardless of the sophistication of the recordkeeping method.
    2. Gain an understanding of the taxpayer's business operations; i.e., how income is generated and recorded.
    3. Determine how business assets are safeguarded; i.e., what steps the taxpayer takes to ensure that the business operates as intended and avoid misstatements of financial information.

     

  3. While there is no exhaustive definition of weak internal accounting controls which will impact the scope and depth of the examination of income, examples include:
    1. books and records that cannot be reconciled to the tax return
    2. transactions that are not properly authorized
    3. recorded transactions are not valid
    4. existing transactions are not recorded
    5. transactions are improperly valued
    6. transactions are improperly classified
    7. transaction are recorded at the improper time
    8. transactions are incorrectly summarized
    9. transactions all made by the same person or related parties
    10. significant co-mingling of business and personal funds

     

  4. Weak internal controls alone do not necessarily establish a reasonable likelihood of unreported income under IRC section 7602(e) that justifies the use of a formal indirect method to make the actual determination of tax liability. Examiners must also demonstrate that there are irregularities in the taxpayer's books and records. See IRM 4.10.4.3.3.5.
  5. Example : The fact that a taxpayer does not maintain separate business and personal bank accounts does not, per se, warrant the use of a formal indirect method to make the actual determination of tax liability. The examiner must first determine whether the books and records are reliable, whether the income per the books and records can be reconciled to the return, and whether the taxpayer segregated or identified the sources of funds to properly account for taxable income. The test of whether an examiner can use a formal indirect method to determine the tax liability is whether there is a reasonable indication that there is a likelihood of unreported income.
  6. The workpapers will document:
    1. the conclusions reached by the analysis of internal controls,
    2. the impact on the scope of the examination, and
    3. the impact on the depth of the examination of income.

     

4.10.4.3.3.5  (06-01-2004)
Reconciliation of Income per Books and Records to Income Reported on Tax Return (Individual Business Return)

  1. Reconcile the income reported on the tax return to the taxpayer’s books and records. Ask the taxpayer how income was computed and duplicate the taxpayer's steps. Refer to IRM 4.10.3.5.6, Step 6: Reconciling the Taxpayer's Books and Records to the Tax Return, for complete discussion.
  2. Test the information obtained in the initial interview and from the evaluation of the internal controls to determine if transactions were properly recorded.
  3. If the income per the books and records cannot be reconciled with the income reported on the tax return, ask the taxpayer to provide an explanation for the difference; i.e., how the accounts per books were accumulated for the tax return.
  4. Irregularities in a taxpayer's books and records, or inconsistencies in reporting transactions may be an indication of unreported income justifying the use of a formal indirect method to make the actual determination of tax liability. Example: a taxpayer's books and records are reconciled to the income tax return. No discrepancy is noted when reconciling income to the bank statements and sales journals, or verifying purchases by inspecting cancelled checks and invoices. The examiner also attempted to tie purchases to specific jobs and the income received from those jobs. For a few purchases, there was no corresponding job or income reported.
  5. The lack of books and records, or the underlying source documents will justify expansion of an income probe beyond the minimum income probes. Example: the taxpayer owns and operates a cash-intensive food service business. The taxpayer's books and records tie to the tax return. As part of the audit, the examiner should test gross receipts by tying the original source documents (cash register receipts and/or invoices) to the books. However, the taxpayer does not have the original documents.
  6. The fact that a taxpayer's books and records were not prepared contemporaneously to the business activity does not, per se, permit an examiner to use a formal indirect method to make the actual determination of tax liability. The test of whether a formal indirect method can be used is whether there is a reasonable indication that there is a likelihood of unreported income. Example: a taxpayer advises an examiner during an audit that the books were prepared after the end of the tax year based on bank statements and cancelled checks.

4.10.4.3.3.6  (06-01-2004)
Bank Account Analysis (Individual Business Return)

  1. Perform an analysis of the taxpayer's business and personal bank accounts; i.e., statements, deposit slips, and canceled checks, etc. The Service is not prohibited from asking for these records, as well as wire transfers, on the initial information document request (IDR) or at any time during the examination for an individual business return.
  2. This analysis is used to
    1. identify deposits which may be taxable income,
    2. determine whether business expenses mayhave been paid from other sources (such as Cash-on-Hand or Accumulated Funds) or are overstated, and
    3. estimate the risk of co-mingled personal and business bank accounts, and
    4. whether cash is deposited.

     

  3. The steps of the Bank Account Analysis are:
    1. Analyze the deposits. Look for unusual deposits (size or source), general frequency of deposits, deposits of cash, specific deposits that do not follow the taxpayer's normal routine or pattern, nontaxable deposits such as loans and transfers, co-mingling of personal and business activities, and cash-backs when a deposit is made.
    2. Total the deposits and reconcile deposits of nontaxable funds and transfers between accounts. Particular attention should be paid to transfers in, out, and between accounts as previously unknown accounts may be identified. Checks deposited by the taxpayer but later returned by the bank (e.g., the maker of the check did not have sufficient funds in the account to pay the check) should be categorized as a nontaxable transactions. Note: this step is a duplication of the reconciliation of income reported on the tax return to the taxpayer's books and records if the taxpayer reported income based on bank deposits.
    3. Determine disbursements by adding the opening bank balance to the total deposits and then subtracting out the ending balance.
    4. Conduct a cursory review of cancelled checks to determine whether nondeductible expenditures (personal expenses, investments, payments on asset purchases, etc.) are included with business expenses and if so, the dollar amount. Significant co-mingling of accounts warrants a more in-depth analysis.
    5. Subtract the nondeductible expenditures from the total disbursements. The remainder should approximate the deductible business expenses on the tax return (other than noncash expenses such as accruals and depreciation). NOTE: It may be easier to identify the business expenditures in some cases, which can then be subtracted from the total disbursements; the remainder will be personal expenses paid by check.

     

  4. Compare the total deposits with the reported Gross Income. Include all accounts, whether designated as personal or business.
  5. If the analysis results in the identification of excess deposits over reported Gross Income, the excess represents potential unreported income.
    1. If specific transactions or deposits can be identified as the source of the understatement, a specific item adjustment to income supported by direct evidence should be made.
    2. If the specific transactions or deposits creating the understatement are not identified, an adjustment to taxable income may be made based on the circumstantial evidence. Technically, this is an adjustment due to the use of an indirect method. However, IRC 7602(e) governing the use of Financial Status Audit Techniques, is not triggered because the adjustment stems from an analysis of the taxpayer's books and records and is not intrusive. See IRM 4.10.4.2.9, Indirect Method.

     

  6. If the business expenditures paid by check are less than the deducted business expenses on the return, then the taxpayer may be overstating expenses, paying expenses by cash (unreported income), or paying expenses from an undisclosed source of funds.
  7. If the analysis indicates significant co-mingling of funds, then the internal controls are weak and the books and records may be unreliable. (See IRM 4.10.4.3.3.4.)
  8. A potentially material misstatement of taxable income identified through a bank account analysis establishes a reasonable likelihood of additional unreported taxable income justifying the use of a formal indirect method to make the actual determination of tax liability.

4.10.4.3.3.7  (06-01-2004)
Business Ratio Analyses (Individual Business Return)

  1. The initial reconciliation of income per the books and records to the tax return provides the examiner with an understanding of how the taxpayer determined gross receipts. The books and records can also be used to evaluate the accuracy and reasonableness of the reported amount of income through the use of ratios.
  2. Horizontal Analysis - This analysis identifies changes over time and may result in the identification of LUQ items not readily identified from a review of a single return alone. The tax return under audit should be compared to the prior and subsequent year returns.
    1. Examiners should consider absolute numeric entries, changes in key ratios, and any other changes indicative of a change in financial activities. The analysis should be based on expenses that vary with changes in production or volume of sales.
    2. The analysis should include all schedules that report financial activity, including Schedules C, D, and E.
    3. The analysis can be documented by notes on the MACS prints, or a prepared schedule.
    4. This analysis should be completed in conjunction with the Required Filing Checks under IRM 4.10.5.3.
    5. Significant variations (5% or more) suggest changes in business or reporting practices that need to be discussed with the taxpayer.

     

  3. Example : In many industries, Cost of Goods Sold bears a direct relationship to Sales. An analysis of the prior and current year business ratios indicates consistency between years. The analysis for the current and subsequent year indicates a change in business practices that should be explained by the taxpayer.
    Prior and Current Year
      Prior Year Current Year Change % Change
    Sales $90 $100 $10 11%
    COGS $27 $30 $3 11%
    Fixed Costs $30 $30 0 0
    Net Income $33 $40 $7 21%

     

    Current and Subsequent Year
      Current Year Next Year Change % Change
    Sales $100 $130 $30 30%
    COGS $30 $42 $12 40%
    Fixed Costs $30 $30 0 0
    Net Income $40 $58 $18 25%

     

  4. Vertical Analysis - This analysis identifies differences between the taxpayer's business and the industry standards for a given year and is an indicator of the reasonableness of gross receipts and net profit reported on the tax return. Industry statistics can be found at www.bizstats.com.
    1. Expenses are expressed as a percentage of gross receipts.
    2. Potential underreporting of income which equals 10% or more of the reported income should be resolved with the taxpayer's assistance. Discrepancies can be caused by errors in reporting gross receipts, inventory, or purchases. See IRM 4.10.3.9.1, paragraphs 12, 13, and 14 for lists of possible errors.
    3. A comparison against industry norms alone, which indicates a discrepancy, is not justification for using a formal indirect method to make the actual determination of tax liability.

     

  5. Example : A quick analysis of the taxpayer's business activity can be based on the following ratio.
    Cost of Sales
    Gross Receipts from Sales
    The following schedule represents the gross receipts and expenses reported by a taxpayer. Assume that there are no inventories.
    Gross Receipts   $330,000
    Material $150,000  
    Labor $120,000  
    Subcontractors $30,000  
    Cost of Goods Sold   $300,000
    Gross Profit   $30,000
    The taxpayer's cost of goods sold to sales ratio is $300,000/$330,000 = 91%. The industry standards however is 75%. To estimate the potential underreporting of income, use the industry standard and the taxpayer's reported costs. $300,000/Gross Receipts = 75%
    Based on the industry standards, the Gross Receipts should be about $400,000. The potential underreporting of income is $400,000 - $330,000 = $70,000.
  6. Examiners are not limited to the ratio demonstrated above. Any ratio or standard available for the taxpayer's industry can be used for the analysis. See IRM 4.10.3.9.1, Gross Profit Ratio Test.
  7. Example : The taxpayer is the sole proprietor of a bar. The examiner reviews the taxpayer's books and records, and tests the gross receipts as a percentage of purchases. The taxpayer states that his markup percentage is approximately 150%, which the examiner knows is consistent with industry practices. However, the examiner determines that the actual markup percentage is 100%. Based on the taxpayer's oral testimony and the industry practice, it appears that the taxpayer may not be reporting all of the gross receipts.
  8. Example : The taxpayer sells pianos. The examiner selected a sample of four actual purchases and subsequent sales by the taxpayer; the average markup for the four piano sales was 51.7%. Overall, for the business as reported on Schedule C, the markup is 27%. Based on the comparison, it appears that the taxpayer may not be reporting all of the gross receipts.

4.10.4.3.4  (06-01-2004)
Minimum Income Probes: Corporations and Other "Business " Returns

  1. An examination of gross income on a business return for a corporation or other business entity should include the following minimum steps:
    1. Complete a Balance Sheet Analysis
    2. Reconcile Schedules M-1 and M-2
    3. Evaluate the tax returns of significant shareholders or partners (greater than 20% direct or indirect ownership)
    4. Interview the taxpayer
    5. Tour of the business site
    6. Evaluation of the internal controls
    7. Test Gross Receipts or Sales

     

4.10.4.3.4.1  (06-01-2004)
Balance Sheet Analysis

  1. Prepare an analysis of the balance sheet and tax return information. The purpose of the analysis is to assist in the identification of issues to be examined. Significant changes to any accounts should be noted and resolved during the examination.
  2. Use CFOL information or secure copies of subsequent and prior year returns from the taxpayer to complete the comparative analysis when the examination is initiated.
  3. Analyze significant balance sheet accounts which show substantial increases or decreases that may indicate the misclassification of income and accounts. Examples include "loans to shareholders," suspense accounts, deferred income accounts, and reserve accounts. Tie balance sheet accounts, such as Cash, to their respective source documents, such as the bank reconciliations and Accounts Receivable to the receivable subsidiary ledger ending balance.
  4. Compare the adjusted trial balance to the balance sheet to ensure they match. Account grouping sheets should be requested for this analysis. This is an essential step in the examination of a double-entry set of books.
  5. Review the adjusting journal entries from the unadjusted trial balance to the adjusted trial balance for misclassifications, unusual debits to income accounts or possible manipulations of reported income. The adjusted trial balance should be tied to the general ledger to ensure there are no missing adjusting journal entries. The general ledger should be scanned for large, unusual or questionable items in the journal entries or adjusting journal entries, such as debit entries to income accounts or credit entries to asset accounts (i.e. Accounts Receivable that do not flow from the Cash Receipts journal).
  6. See IRM 4.10.3 for additional instructions.

4.10.4.3.4.2  (06-01-2004)
Schedules M-1 and M-2

  1. Perform a reconciliation of Schedules M–1, Reconciliation of Income/Loss Per Books with Income Per Return, or equivalent schedule and M–2, Analysis of Unappropriated Retained Earnings per Books, or equivalent schedule.
  2. Refer to IRM 4.10.3.6 for complete discussion.

4.10.4.3.4.3  (06-01-2004)
Required Filing Checks

  1. Evaluate copies of the tax returns of significant shareholders or partners (greater than 20% direct or indirect ownership) for:
    • examination potential (including issues unrelated to the corporate or partnership return),
    • the proper treatment of related transactions with the corporation or partnership, including losses from related parties, and
    • the likelihood of diverted funds

     

  2. Completion of the Required Filing Checks (see IRM 4.10.5) is not a violation of IRC section 7602(e).
  3. Copies of related shareholder/partner returns can be obtained using CFOL or MACS. If the CFOL and MACS information is insufficient, the return should be requested from either the campus or the taxpayer for inspection. See IRM 4.10.5.2.2.
  4. Examiners should determine if the income from the related business entity was included on the shareholder/partner's individual return. If the income was reported and there are no other issues, the return should not be opened for examination. If the income from the related business entity was not reported on the return, the examiner should open the shareholder/partner's individual return for audit.
  5. Independent of the potential underreported income from the business entity, the return should be opened for audit if the examiner notes that a Financial Status Analysis based on the return indicates insufficient funds to support the identified expenses, or a large, unusual, or questionable item is identified.
  6. Effectively, examiners should determine whether the related return warrants examination from a classification perspective; i.e., trace the transactions between the individual and related business entity, complete a Financial Status Analysis based on the return as filed and internal sources of information (see Exhibit 4.10.4-2), and review the return for other potential issues.
  7. Should the related individual return be opened for audit, it is subject to the minimum income probes and examiners are expected to determine whether the taxpayer has reported the correct amount of taxable income. The depth of the examination of income and the techniques used are dependent on the facts and circumstances of the case.

4.10.4.3.4.4  (06-01-2004)
Initial Interview

  1. This interview, wherever possible, should be held with the partnership's Tax Matters Partner (TMP) or the corporate officer most familiar with the day-to-day operations of the business. From the taxpayer's perspective, an interview with an Internal Revenue agent may be overwhelming. Therefore, initial interviews should be professional and not overbearing; the taxpayer should be afforded 100% credibility.
  2. IRC section 7521(c) states that examiners cannot require a taxpayer to accompany an authorized representative to an examination interview in the absence of an administrative summons. However, the taxpayer’s voluntary presence can be requested through the representative. Should an examiner find that a representative has unreasonably delayed or hindered an examination, an examiner can bypass the representative and deal directly with the taxpayer. See Exhibit 4.10.4-5, Bypassing Powers of Attorney.
  3. Question the TMP, corporate officer, or representative concerning possible loans, gifts, or other nontaxable funds, known errors/omissions on the return, unreported sources of income and ask for any information necessary to resolve issues identified during the pre-audit analysis.
  4. Question the TMP, corporate officer or representative about Cash on Hand and Accumulated Funds. See IRM 4.10.4.3.3.2, IRM 4.10.4.6.8.3, and Exhibit 4.10.4-1 for additional discussion.
  5. Question the TMP, corporate officer or representative about internal controls. Segregation of duties and flow of money should be established to determine any potential control weaknesses which could result in diversion of funds.
  6. IRC section 7521(b) (2) requires examiners to suspend interviews when taxpayers state that they wish to consult with a representative or otherwise seek advice. The taxpayer’s right of consultation will be strictly honored and interviews will be suspended and rescheduled accordingly. This provision does not apply to interviews initiated by administrative summons and will not be used to repeatedly delay or hinder the examination process.

4.10.4.3.4.5  (06-01-2004)
Tour of Business Sites (Corporations and Other "Business " Returns)

  1. Conduct a tour of the business site. Generally, the principal location and any other locations acquired during the period under examination should be visited. The purpose of a tour is to:
    1. gain familiarity with the taxpayer’s business operation and internal controls,
    2. identify potential sources of income, and
    3. confirm the existence of assets.

     

  2. The results of a tour and any observations and/or comments should be documented in the examination workpapers.
  3. See IRM 4.10.3.3 for complete discussion.
  4. This requirement applies to Field examinations only.

4.10.4.3.4.6  (06-01-2004)
Evaluate Internal Controls

  1. Evaluate the internal controls to gain an understanding of the taxpayer’s business operations and control features. See IRM 4.10.3.4.
  2. While there is no exhaustive definition of weak internal accounting controls, which will impact the scope of the examination of income, examples include:
    1. books and records that cannot be reconciled to the tax return
    2. transactions that are not properly authorized
    3. recorded transactions are not valid
    4. existing transactions are not recorded
    5. transactions are improperly valued
    6. transactions are improperly classified
    7. transaction are recorded at the improper time
    8. transactions are incorrectly summarized
    9. transactions all made by the same person or related parties
    10. recording and handling of assets by the same person or related parties

     

  3. Example : a taxpayer's business consists of small home repairs and construction projects. The taxpayer files a S-corporation tax return. The books and records tie to the S-corporation's income tax return and the invoices tie into the gross receipts shown on the return. The S-corporation return reflects a net profit of $5,000. The S-corporation did not pay the taxpayer a salary, but the taxpayer's spouse earned $30,000 in wages from an unrelated business (as reported on the shareholder's 1040 tax return). Although the cash flow analysis suggests sufficient funds to support the S-corporation's expenses, most of the gross receipts are cash and the internal controls are weak because the taxpayer's spouse maintains the books.
    1. The S-corporation and shareholder income tax returns are considered related because the returns are for entities over which the taxpayer has control and which can be manipulated to divert funds or camouflage transactions. Therefore, the examination of the S-corporation cannot be completed without also examining the taxpayer's individual return.
    2. Once an audit of the related individual return is initiated, the examiner should request the personal bank records (statements, cancelled checks and deposit slips) for both spouses to determine if any corporate funds were diverted.
    3. If, after reviewing these records, the examiner believes there is a reasonable indication that there is a likelihood of unreported income, a formal indirect method may be used to make the actual determination of tax liability.

     

  4. The workpapers will document:
    1. the conclusions reached by the analysis of internal controls,
    2. the impact on the scope of the examination, and
    3. the impact on the depth of the examination of income.

     

4.10.4.3.4.7  (06-01-2004)
Test Gross Receipts or Sales

  1. Test the information obtained in the initial interview and from the evaluation of the internal controls to gain a complete understanding of the taxpayer’s business operations and control features.
  2. Reconcile the bank records. The depth of bank record inspection will depend on the reliability of internal controls and the judgment of the examiner. Consider the results of the analysis of the primary shareholders’ or partners’ individual returns. See IRM 4.10.3.7. The initial IDR may include a request for the business bank records, including the statements, deposit slips and cancelled checks.
  3. See IRM 4.10.3.9 for a complete discussion and listing of audit techniques.

4.10.4.3.5  (06-01-2004)
Minimum Income Probes: Delinquently Filed Returns & Nonfilers

  1. Delinquent returns filed at a campus or with an examiner are subject to the same minimum requirements for the examination of income as are timely filed returns.
  2. If a Financial Status Analysis (or another analysis) based on a return secured from a nonfiler as part of an examination indicates that there is a likelihood of unreported income, then an in-depth examination of income should be completed and a formal indirect method used to make the actual determination of tax liability if warranted.
  3. For more information regarding nonfilers, refer to IRM 4.12, Nonfiler Returns.
  4. Substitutes for return(s) filed on behalf of a nonfiler under IRC section 6020(b) will require a reconstruction and examination of income. The examiner should secure and review available internal information to use in the determination of the scope of examination of income. (See Exhibit 4.10.4–2.) The examiner should also have Bureau of Labor Statistics (BLS) information available for comparison to the nonfiler’s record of gross income. Examiners should attempt to use the nonfiler’s books and records to prepare a preliminary schedule of gross income. Based upon the nonfiler’s schedule of gross income, available internal information and BLS data, the examiner must determine the subsequent audit scope using the following criteria:
    IF THEN
    The nonfiler’s schedule of gross income prepared from his/her books and records is consistent with all financial activities of the nonfiler and available internal information, The substitute for return may be prepared using the nonfiler’s record of gross income. The results and conclusions reached should be documented in the examination workpapers.
    IF THEN
    The nonfiler’s schedule of gross income prepared from his/her books and records is inconsistent with the financial activities of the nonfiler and/or available information, A more in-depth examination of income is warranted. See IRM 4.10.4.5 below for suggested elements of an in-depth examination income for an individual nonfiler. Note: Collectibility consideration should be given to each situation in which the examination scope may be expanded.

4.10.4.4  (06-01-2004)
Results of Minimum Income Probes

  1. After completion of the minimum income probes, the examiner must evaluate the information collected to this point and determine the scope of the examination of income, using the following criteria:
    IF THEN
    The results show that the taxpayer reported all taxable income from known sources, the books and records can be reconciled to the tax return, all financial activities are in balance, and the bank deposits do not exceed reported income, The examination of income may be limited to the Minimum Income Probes. The results and conclusions reached should be documented in the examination workpapers.
    IF THEN
    The results indicate the potential of unreported income due to inaccurate reporting of taxable income from known sources, the books and records cannot be reconciled to the tax return, a material imbalance in the Financial Status Analysis that cannot be reconciled, excess unexplained bank deposits, or inadequate internal control, A more in-depth examination of income is warranted. See subsection 4.10.4.5 below for suggested guidelines for an in-depth examination of income.

     

4.10.4.4.1  (06-01-2004)
Material Understatements and Managerial Involvement

  1. If the examination of income reveals an understatement of income in a given year, the case should be discussed with the group manager. The purpose of the discussion is to consider possible expansion of the examination scope/depth, audit techniques to be used, and the potential of fraudulent activity by the taxpayer.
  2. This discussion is mandatory in any examination with an understatement of income greater than $10,000.
  3. This discussion should be noted on Form 9984, Examining Officer's Activity Record. A summary of the content and resulting decisions should be documented in the workpapers.
  4. Group Managers should be engaged with their examiners in the development of unreported income issues. Involvement can be demonstrated by:
    1. Becoming familiar with the factual development and documentation,
    2. Discussing cases with examiners to assist in the determination of the depth of the examination of income and the techniques that should be used,
    3. Assisting examiners to determine whether the facts support the conclusion that there is a reasonable likelihood of unreported income justifying the use of a formal indirect method to make the actual determination of tax liability.
    4. Issuing summonses when necessary, and
    5. Contacting TIGTA immediately when a taxpayer threatens to report an RRA '98 Section 1203 violation for harassment.

     

  5. Management involvement should be annotated on Form 9984, Examining Officer's Activity Record.

4.10.4.4.2  (06-01-2004)
Inadequate Books and Records

  1. Whenever the taxpayer’s books and records are deemed inadequate for purposes of an examination of income, the examiner should consider the issuance of an inadequate records notice at the conclusion of the examination. See IRM 4.10.8.15 for procedures to issue an inadequate records notice.

4.10.4.5  (06-01-2004)
In-Depth Examinations of Income

  1. If, as a result of completing the minimum income probes, the examiner identified inaccurate reporting of income from known sources, cannot reconcile the income reported on the tax return to the taxpayer's books and records, cannot reconcile a Financial Status Analysis, identified unexplained bank deposits, determined that the taxpayer's internal controls are inadequate, or determined for any reason that there is reasonable indication of additional unreported income, then a more in-depth examination of income will be made.

4.10.4.5.1  (06-01-2004)
Guidelines for In-Depth Examinations of Income

  1. The depth of the in-depth examination of income will be tailored to each taxpayer. Sensitivity to the taxpayer’s reaction to additional in-depth probes must be balanced with the need for the proper and fair administration of tax laws.
  2. The in-depth examination of income is distinguishable from the minimum income probes by the use of third party contacts to obtain information or evidence to reconcile income issues.
  3. Where indicated, examiners should first pursue specific items of income that can be documented with direct evidence. These adjustments are easiest to defend and may eliminate the need to use a formal indirect method to make the actual determination of tax liability. This approach is appropriate when the taxpayer maintains books and records, adjustments may be due to technical issues (such as timing or character of funds), or the potential sources of the unreported income are limited (such as an insurance agent who underwrites for several companies). The specific item approach is not useful if the taxpayer’s gross receipts are generated from numerous sources or in small amounts, such as a grocery store.
  4. The use of a formal indirect method to make the actual determination of tax liability should be pursued when the taxpayer’s books and records are missing, incomplete, or irregularities are identified; or the Financial Status Analysis indicates a material imbalance after consideration of specific adjustments identified during the examination. Choosing the formal indirect method most suitable for the examination is extremely important. See IRM 4.10.4.6.2. for addition discussion.
  5. Procuring evidence, and its evaluation, are an integral part of the process. Refer to the following IRM sections:
    1. IRM 4.10.7.3, Evaluating Evidence, which includes discussions of oral testimony, observations, and documentary evidence.
    2. IRM 4.10.7.4, Arriving at Conclusions, which includes a discussion of taxpayer credibility and reasonable determinations.

     

4.10.4.5.2  (06-01-2004)
In-Depth Examinations of Income—Individual Taxpayers

  1. Follow-up on evidence of potential sources of additional unreported income. This audit technique does not trigger the provisions of IRC section 7602(e) regarding the use of Financial Status Audit Techniques; thus, there is no requirement that the Service to have a reasonable indication of a likelihood of unreported income.
  2. Attempt to resolve an unbalanced Financial Status Analysis.
    1. Reduce the unexplained understatement of income by any excess of net bank deposits over reported gross receipts discovered during the bank account analysis.
    2. Include any audit adjustments made due to failure to substantiate claimed expenses. NOTE: The Financial Status Analysis should be continually revised as new information about business and personal expenses becomes available.
    3. Update estimated personal living expenses as information becomes available. However, it is inappropriate to affirmatively ask the taxpayer to identify actual personal living expenses or complete Form 4822, Statement of Annual Estimated Personal and Family Expenses. For purposes of the Financial Status Analysis, estimated personal living expenses are sufficient. Refining personal living expenses for actual costs should be limited to completion of a formal indirect method to make the actual determination of tax liability. See IRM 4.10.4.6.1.2.

     

  3. Discuss any potential understatement of income with the taxpayer and/or representative. The taxpayer may have information that was not previously disclosed to the examiner that will resolve the imbalance.
    1. Consideration should be given to credible oral testimony, such as reasonableness of gifts of cash from relatives. (See IRM 4.10.7.3.2 for in-depth discussion of oral testimony and documentation requirements.)
    2. Loan proceeds should be documented with the loan application and records of disbursement. The documents should be reviewed to confirm the amount and terms of the loan, as well as determining if the information on the loan application is consistent with information on the return. Differences should be reconciled and may lead to additional sources of income.

     

  4. When appropriate, third party contacts should be made to corroborate oral testimony. Information should be collected, to the greatest extent practicable, directly from the taxpayer to whom it relates. However, external sources of information (third parties) can be used to update the Financial Status Analysis, verify expenses, or corroborate the taxpayer's oral testimony and explanations.
    1. Under Section 7602(c) of the Code, third party contacts may not be initiated before giving advance notice to the taxpayer that contacts other than with the taxpayer may be made.
    2. Request that the taxpayer complete Form 6014, Authorization — Access to Third Party Records for Internal Revenue Service Employees. This form gives a third party written authorization from the taxpayer to provide information directly to the examiner.
    3. Use standard Form Letter 1995, Third Party Contact Letter to Request Information, to request information from third parties.
    4. Issue an administrative summons to the third party if the taxpayer is not cooperative. Pursuant to IRC section 7602(a), the Service has the authority to issue a summons to any person who has information for any bona fide civil tax audit, collection purpose or criminal investigation of any offense connected with the administration or enforcement of the internal revenue laws. To enforce an administrative summons, the Service must demonstrate that (1) there is a legitimate purpose; (2) the inquiry is relevant to the purpose; (3) the information is not already in the possession of the Service; and (4) the administrative steps required by the Code and regulations have been followed. See United States v. Powell, 379 U.S. 48, 57-58 (1964).
    5. A variety of external sources of information are available. For example, a credit application completed by the taxpayer to secure a bank loan may reflect income consistent with the audit adjustment. See Exhibit 4.10.4–3 for additional examples of external sources of information.
    6. Information from third parties may be secured via telephone with the taxpayer present. This is the easiest and most efficient method. Depending upon the information sought, oral testimony may be all that is needed to resolve the issue.
    7. In some circumstances interviewing the third party should be considered. A summary of the interview or statement made should be prepared and signed by the third party. If a more formal written statement is desired, an affidavit (Form 2311) should be used. See IRM 4.10.7.3.2, Oral Testimony, for detailed discussion.
    8. Information from third parties will be verified, to the extent practicable, with the taxpayer or representative before action is taken. (See IRM 4.10.1.6.12 for more information on taxpayer notification requirements.)

     

4.10.4.5.3  (06-01-2004)
Audit Techniques for the In-Depth Examinations of Income: Corporations, Other "Business" Returns

  1. The minimum income probes described in IRM 4.10.4.3.4 are comprehensive. Therefore, examiners should use their judgment when determining which audit techniques are most suitable for additional in-depth income probes. Refer to IRM 4.10.3.5.5 and 4.10.3.5.6.
  2. Bank records serve as backup documents to the taxpayer's records and can also provide leads to transactions not disclosed in the books and records. A complete discussion is included in IRM 4.10.3.7. The extent of the bank account reconciliation will depend on the circumstances of the case and will be more important when records are inadequate, nonexistent, or possibly falsified.
  3. An apparent understatement of income for a corporation or other business entity will normally require a concurrent in-depth examination of the related shareholders or partners. Refer to IRM 4.10.5.4 for suggested elements for an in-depth examination of income for an individual shareholder/partner. Refer to IRM 4.10.4.6 below for general guidance for using formal indirect methods.
  4. When appropriate, third party contacts should be made to corroborate oral testimony. See IRM 4.10.4.5.2(4) for complete discussion.

4.10.4.5.4  (06-01-2004)
Results of an In-Depth Examination of Income

  1. After completion of the in-depth examination of income, the examiner should decide the next step using the following decision criteria:
    a. IF THEN
      The taxpayer or third parties have successfully explained the reason for the understatement. Document the results in the workpapers and conclude the examination of income without adjustment.
    b. IF THEN
      The adjustments to income and understatement meet the criteria for referral to Criminal Investigation. A referral should be made to Criminal Investigation.
    c. IF THEN
      The taxpayer agrees to the proposed adjustments to income. There is no indication of additional unreported income. Document the results in the workpapers and make the adjustment, resolve other issues, and close the case agreed.
    d. IF THEN
      The taxpayer does not agree to the proposed adjustments to income and the adjustments are not based on estimated personal living expenses. Document the results in the workpapers and close the case unagreed.
    e. IF THEN
      The taxpayer does not agree to the proposed adjustments to income and the adjustments are based on estimated personal living expenses. Consider using one of the formal indirect methods to make the actual determination of tax liability. (A case should not be closed unagreed if adjustments to income are based on estimated Personal Living Expenses.)

     

4.10.4.6  (06-01-2004)
Formal Indirect Methods of Determining Income

  1. The formal indirect methods used to determine tax liabilities involve the development of circumstantial proof of income through the use of bank deposits, source and application of funds, ratio analyses, or changes in net worth.
  2. The purpose of this section is to provide guidance for examiners when using formal indirect methods of reconstructing income. The five basic formal indirect methods of reconstructing income discussed are:
    1. Bank Deposits and Cash Expenditures Method
    2. Source and Application of Funds Method
    3. Markup Method
    4. Unit and Volume Method
    5. Net Worth Method

     

  3. Subsection 4.10.4.6, Formal Indirect Methods of Determining Income, is organized into the subsections listed below. Key court decisions which allow for the use of formal indirect methods, when to use a specific method, formulas, and examples are included in the discussions of the different methods. Common defenses which an examiner may encounter in cases where a formal indirect method is used are also discussed.
    4.10.4.6.1 Authority to Use Formal Indirect Methods
    4.10.4.6.2 Using Formal Indirect Methods to Reconstruct Income
    4.10.4.6.3 Bank Deposits and Cash Expenditures Method
    4.10.4.6.4 Source and Application of Funds Method
    4.10.4.6.5 Percentage of Markup Method
    4.10.4.6.6 Unit and Volume Method
    4.10.4.6.7 Net Worth Method
    4.10.4.6.8 Potential Taxpayer Defenses Against Formal Indirect Methods of Computing Income

     

4.10.4.6.1  (06-01-2004)
Authority to Use Formal Indirect Methods (Financial Status Audit Techniques)

  1. Neither the Code or the regulations define or specifically authorize the use of the formal indirect methods. IRC section 446(b), however, provides that if no method of accounting has been regularly used by the taxpayer, or if the method used does not clearly reflect income, the computation of taxable income shall be made under such method as, in the opinion of the Secretary, does clearly reflect income.
  2. If the examiner has a reasonable indication that unreported income exists, the IRS has been granted the authority, through the development of case law, to use a formal indirect method of reconstructing income to determine whether or not the taxpayer has accurately reported total taxable income received.
  3. The [formal] indirect method need not be exact, but must be reasonable in light of the surrounding facts and circumstances. Holland v. United States, 348 U.S. 121, 134 (1954).

4.10.4.6.1.1  (06-01-2004)
Limitation on Use of Formal Indirect Methods (Financial Status Audit Techniques)

  1. Formal indirect methods and the techniques used to support their development are collectively known as "Financial Status Audit Techniques " and trigger IRC section 7602(e), which states that " the Secretary shall not use financial status or economic reality examination techniques to determine the existence of unreported income of any taxpayer unless the Secretary has a reasonable indication that there is a likelihood of such unreported income."
  2. "Financial Status Audit Technique" was defined as the use of formal indirect methods in the Government Accounting Offices's report, "More Criteria Needed on IRS' Use of Financial Status Audit Techniques," GAO/GGD-98-38.

4.10.4.6.1.2  (06-01-2004)
Limitation on Use of Examination Techniques: Personal Living Expenses

  1. "Examination techniques" include examining and testing the taxpayer's books and records, analytical tests, observing, and interviewing the taxpayer. None of these techniques are unique to the use of a formal indirect method and do not trigger the limitation of IRC section 7602(e). The refinement of the personal living expenses (PLE) for actual costs (rather than estimates), however, is an intrusive examination technique that should only be used after the decision to use a formal indirect method to determine the actual tax liability has been made.
  2. Form 4822, Statement of Annual Estimated Personal and Family Expenses, may be used as a guide by the examiner for determining the taxpayer's personal living expenses. The form lists the typical expenses incurred by most individuals.
  3. It is inappropriate to ask the taxpayer to complete the form independently. The examiner must make sure the taxpayer understands what is required to accurately complete each expense item. The discussion required to complete the form can often provide the examiner with information about the taxpayer, which may help clarify potential issues and adjustments.
  4. Care should be taken to avoid duplicating amounts when modifying estimates for actual costs.

4.10.4.6.1.3  (06-01-2004)
Use of Bureau of Labor Statistics Data to Reconstruct Taxable Income

  1. In certain cases, as described below, income may be reconstructed using Bureau of Labor Statistics (BLS) data. The analysis is completed using the tables for annual expenses, not income, because determining the expenses represents a better reflection of the actual costs to maintain a household.
  2. The BLS data can be accessed at www.bls.gov, select " Inflation and Consumer Spending." Tables specific to year, region within the United States, and individual expenses are available.
  3. BLS data cannot be used as a substitute for reconciling the taxpayer's books and records. If the taxpayer provides information, or information becomes available, which shows that income in a specific amount was earned, BLS data cannot be used to increase income to the national average.
  4. In court proceedings involving individuals, IRC section 7491(b) may shift the burden of proof. Section 7491(b) provides that the Service will have the burden of proof for any item of income where income is reconstructed using only BLS data or other statistical information on unrelated taxpayers.

4.10.4.6.1.3.1  (06-01-2004)
When to Use Bureau of Labor Statistics Data

  1. BLS data should be used as a method to calculate taxable income where the following three conditions are met.
    1. The taxpayer is in a business or income producing activity other than as an employee. Evidence of employment and wages earned, such as a filed Form W-2, constitutes evidence precluding the use of BLS unless the taxpayer can be placed in an unrelated income producing activity that could have generated unreported income. See Senter v. Commissioner, T.C. Memo 1995-311.
    2. The taxpayer must be a nonfiler. If the taxpayer filed a tax return and reported income, then the examiner must use other recognized methods (specific item, indirect methods) to confirm or reconstruct additional income. BLS statistics are not a substitute for obtaining and considering relevant evidence in reaching a determination.
    3. The taxpayer must be uncooperative with the examiner during the audit. Examples of noncooperation include a taxpayer who is not willing to meet with the examiner or provide any information or records regarding income producing activities, whether or not the examiner has been able to actually identify that activity. Examiners must use judgment to determine whether the taxpayer is cooperative. Examiners must use all available administrative tools, including the summons enforcement, to gather necessary information before BLS data is used.

     

4.10.4.6.1.3.2  (06-01-2004)
Case Law for Using Bureau of Labor Statistics Data

  1. In Miller v. Commissioner, T.C. Memo 1993-121, the taxpayer filed tax returns for 1982-1985, but they contained virtually no information other than his name, address, occupation, filing status, and the number of exemptions claimed. The various line items on the returns either stated "none" or were footed to statements containing specific objections based upon amendments to the United States constitution. The taxpayer signed the returns, but added a disclaimer. The taxpayer was totally uncooperative during the audit and did not provide books or records. Bank records were used to reconstruct the taxpayer's business receipts and expenses. Because the bank records reflected virtually no personal expenditures, BLS cost-of-living data was used to determine income attributable to some other untraced source from which personal expenses were paid in addition to the reconstructed gross business receipts. The Court sustained the use of BLS data under these circumstances, except where the BLS figures appeared to be duplications of expenses paid from the bank accounts.
  2. In Portillo v. Commissioner, 932 F.2d 1128 (5th Cir. 1991), the examiner relied upon a filed Form 1099 to determine that a taxpayer had additional unreported income. The taxpayer agreed he had additional income, but not the amount reported on the Form 1099. Ultimately, the filer of the Form 1099 was only able to document the portion of additional income with which the taxpayer agreed. The statutory notice of deficiency reflected the entire amount shown on the Form 1099. The Court found that the notice of deficiency was arbitrary because it merely matched the taxpayer's return with the Form 1099, assuming the taxpayer's return was false and the Form 1099 was correct. In such circumstances, the Service is obligated to investigate.
  3. In Senter v. Commissioner,T.C. Memo 1995-311, the taxpayer failed to provide requested information or appear for scheduled meetings. The taxpayer's correspondence with the examiner raised " protestor" type arguments. The taxpayer did not comply with, and objected to, administrative summonses, but the examiner did not seek enforcement. The notice of deficiency reflected unreported income determined using prior year reported earnings adjusted by the Consumer Price Index (CPI). The Court held this determination of unreported income to be arbitrary and erroneous. Some predicate (preexisting) evidence establishing income was necessary to support a determination of unreported income.

4.10.4.6.2  (06-01-2004)
Using Formal Indirect Methods to Reconstruct Income

  1. Examiners are cautioned that the use of a formal indirect method will be determined on a case by case basis. The use of a formal indirect method to make the actual determination of tax liability is not a substitute for reconciling whatever books are maintained by the taxpayer to the tax return. The use of a [formal] indirect method, however, is not precluded by the presentation of books and records. See Lipsitz v. Commissioner, 21 T.C. 917 (1954).

4.10.4.6.2.1  (06-01-2004)
When to Use a Formal Indirect Method

  1. The use of a formal indirect method to make the actual determination of tax liability should be considered when the factual development of the case leads the examiner to the conclusion that the taxpayer's tax return and supporting books and records do not accurately reflect the total taxable income received or the examiner has established a reasonable likelihood of unreported income. The following list, which is not intended to be all inclusive, identifies circumstances that would support the use of a formal indirect method.
    1. A Financial Status Analysis that cannot be balanced; i.e., the taxpayer's known business and personal expenses exceed the reported income per the return and nontaxable sources of funds have not been identified to explain the difference;
    2. Irregularities in the taxpayer's books and weak internal controls;
    3. Gross profit percentages change significantly from one year to another, or are unusually high or low for that market segment or industry;
    4. The taxpayer's bank accounts have unexplained items of deposit;
    5. The taxpayer does not make regular deposits of income, but uses cash instead;
    6. A review of the taxpayer's prior and subsequent year returns show a significant increase in net worth not supported by reported income;
    7. There are no books and records. Examiners should determine whether books and/or records ever existed, and whether books and records exist for the prior or subsequent years. If books and records have been destroyed, determine who destroyed them, why, and when.
    8. No method of accounting has been regularly used by the taxpayer or the method used does not clearly reflect income. (IRC section 446(b).)

     

4.10.4.6.2.2  (06-01-2004)
Selecting a Formal Indirect Method

  1. The selection of a formal indirect method is critical to effectively and efficiently determine the tax liability. For example, although the Bank Deposits and Cash Expenditures Method and the Source and Application of Funds Method are frequently used, they are not the most effective methods if cash is not deposited and/or the cash outlays cannot be determined unless voluntarily disclosed by the taxpayer. Realistically, it may be difficult to identify significant personal acquisitions or expenditure that the taxpayer has deliberately camouflaged. These weaknesses can be overcome by using a formal indirect method based on the taxpayer's business activities to make the actual determination of tax liability; i.e., the Markup Method or Unit and Volume Method.
  2. The following factors should be considered when selecting a formal indirect method:
    1. The industry or market segment in which the taxpayer operates;
    2. Inventories are a principle income producing activity;
    3. Suppliers can be identified and/or merchandise is purchased from a limited number of suppliers,
    4. Merchandise and/or service pricing is reasonably consistent,
    5. The volume of production and variety of products,
    6. Availability and completeness of the taxpayer's books and records,
    7. The taxpayer's banking practices,
    8. The taxpayer's use of cash to pay expenses,
    9. Expenditures exceed income,
    10. Stability of assets and liabilities, and
    11. Stability of net worth over multiple years under audit.

     

4.10.4.6.2.3  (06-01-2004)
Documenting the Decision to Use a Formal Indirect Method

  1. The reasons why the examination of income was expanded to include the use of a formal indirect method to make the actual determination of tax liability should be documented in the workpapers, as well as why a specific method was selected. The documentation should include a narrative explaining how the evidence in the file establishes the likelihood of unreported income, and justifying the use of a formal indirect method. The documentation should include:
    1. a summary of the facts relevant to the decision,
    2. procedures and audit techniques used up to that point,
    3. manager's comments (if appropriate),
    4. any other information relevant to the decision, and
    5. conclusions.

     

  2. Document likely sources of taxable income. It is not essential to pinpoint the specific source, but only to indicate the possibility of, or the opportunity for, likely sources of taxable income. To the extent that the possible source(s) can be identified, the more credible the results of a formal indirect method will be. Possible sources can be demonstrated by:
    1. specific omissions,
    2. demonstrating that the taxpayer's business had the capacity to generate more gross receipts, or
    3. comparisons over time.

     

  3. The documentation should be prepared concurrent to the decision; i.e., before using a formal indirect method to make the actual determination of tax liability.

4.10.4.6.2.4  (06-01-2004)
Management Approval

  1. Group Manager approval is not required when initiating the use of a formal indirect method.
