27 CFR § 70.170 - Application of proceeds of levy.
(a) Collection of liability. Any money realized by proceedings under 26 U.S.C. 6331 through 6344, or by sale of property redeemed by the United States (if the interest of the United States in the property was a lien arising under the provisions of 26 U.S.C. enforced and administered by the Bureau), is applied in the manner specified in paragraphs (a)(1), (2), and (3) of this section. Money realized by proceedings under 26 U.S.C. 6331 through 6344, includes money realized by seizure, by sale of seized property, or by surrender under 26 U.S.C. 6332 except money realized by the imposition of a 50 percent penalty pursuant to 26 U.S.C. 6332(d)(2)).
(1) Expense of levy and sale. First, against the expenses of the proceedings or sale, including expenses allowable under 26 U.S.C. 6341 and amounts paid by the United States to redeem property.
(2) Specific tax liability on seized property. If the property seized and sold is subject to a tax imposed by any provision of 26 U.S.C. which has not been paid, the amount remaining after applying paragraph (a)(1) of this section, shall then be applied against such tax liability (and, if such tax was not previously assessed, it shall then be assessed):
(3) Liability of delinquent taxpayer. The amount, if any, remaining after applying paragraphs (a)(1) and (2) of this section, shall then be applied against the liability in respect of which the levy was made or the sale of redeemed property was conducted.
(b) Surplus proceeds. Any surplus proceeds remaining after the application of paragraph (a) of this section shall, upon application and satisfactory proof in support thereof, be credited or refunded by the appropriate TTB officer to the person or persons legally entitled thereto. The delinquent taxpayer is the person entitled to the surplus proceeds unless another person establishes a superior claim thereto.
