If an offer of settlement is extended, the taxpayer
will be notified in writing and payment must be remitted in full within
15 days from the date of notice to the taxpayer, unless specifically
stated otherwise by the Department. No payment plans are allowed for
less than the full taxes, penalty, and interest due. If a payment is
made and the bank does not honor the check, the Department will rescind
the offer in settlement and the full tax liability including penalty and
interest will be due.
Any overpayment of taxes for the following three
years will be retained by the Colorado Department of Revenue and applied
to the tax debt. The taxpayer may not reduce quarterly estimated
payments or the amount of withholding during this time.
