§301.6321-1., Lien for taxes. --If any person liable to pay any tax neglects or refuses to pay the same after demand, the amount (including any interest, additional amount, addition to tax, or assessable penalty, together with any costs that may accrue in addition thereto) shall be a lien in favor of the United States upon all property and rights to property, whether real or personal, tangible or intangible, belonging to such person. For purposes of section 6321 and this section, the term "any tax" shall include a State individual income tax which is a "qualified tax", as defined in paragraph (b) of §301.6361-4. The lien attaches to all property and rights to property belonging to such person at any time during the period of the lien, including any property or rights to property acquired by such person after the lien arises. Solely for purposes of sections 6321 and 6331, any interest in restricted land held in trust by the United States for an individual noncompetent Indian (and not for a tribe) shall not be deemed to be property, or a right to property, belonging to such Indian. For the method of allocating amounts collected pursuant to a lien between the Federal Government and a State or States imposing a qualified tax with respect to which the lien attached, see paragraph (f) of §301.6361-1. For the special lien for estate and gift taxes, see section 6324 and §301.6324-1. [Reg. §301.6321-1.]
