Section 70.98 - Penalty for underpayment of deposits(a)General rule. If any person is required by the provisions of 26 U.S.C. enforced and administered by the Bureau or regulations prescribed thereunder to deposit any tax in a government depository that is authorized under 26 U.S.C. 6302(c) to receive the deposit, and fails to deposit the tax within the time prescribed therefor, a penalty shall be imposed on such person unless the failure is shown to be due to reasonable cause and not due to willful neglect. The penalty shall be: (1) For penalties assessed before October 22, 1986, 5 percent of the amount of the underpayment without regard to the period during which the underpayment continues.(2) For penalties assessed after October 21, 1986, on deposits of taxes required to be made before January 1, 1990, 10 percent of the amount of the underpayment without regard to the period during which the underpayment continues.(3) For deposits of taxes required to be made after December 31, 1989.(i) 2 percent of the amount of the underpayment if the failure is for not more than 5 days,(ii) 5 percent of the amount of the underpayment if the failure is for more than 5 days but not more than 15 days,(iii) 10 percent of the amount of the underpayment if the failure is for more than 15 days,(iv) 15 percent of the amount of the underpayment if the tax is not deposited before the earlier of: (A) The day 10 days after the date of the first delinquency notice to the taxpayer under section 6303, or(B) The day on which notice and demand for immediate payment is given under 26 U.S.C. 6862 or the last sentence of 26 U.S.C. 6331(a) . For purposes of this section, the term "underpayment" means the amount of tax required to be deposited less the amount, if any, that was deposited on or before the date prescribed therefor. Section 7502(e) of the Internal Revenue Code applies in determining the date a deposit is made.
(b)Assertion of reasonable cause. To show that the underpayment was due to reasonable cause and not due to willful neglect, a taxpayer must make an affirmative showing of all facts alleged as a reasonable cause in a written statement containing a declaration that it is made under the penalties of perjury. The statement must be filed with the appropriate TTB officer. If the appropriate TTB officer determines that the underpayment was due to reasonable cause and not due to willful neglect, the penalty will not be imposed.T.D.
