26 CFR § 301.6689-1 - Failure to file notice of redetermination of foreign income taxes.
(a) Application of civil penalty. If a foreign tax redetermination occurs, and the taxpayer failed to notify the Internal Revenue Service (IRS) on or before the date and in the manner prescribed in § 1.905-4 of this chapter, or as required under section 404A(g)(2), for giving notice of a foreign tax redetermination, then, unless paragraph (d) of this section applies, there is added to the deficiency (or the imputed underpayment as determined under section 6225) attributable to such redetermination an amount determined under paragraph (b) of this section. Subchapter B of chapter 63 of the Internal Revenue Code (relating to deficiency proceedings) does not apply with respect to the assessment of the amount of the penalty.
(b) Amount of the penalty. The amount of the penalty shall be equal to -
(1) Five percent of the deficiency (or imputed underpayment) if the failure is for not more than one month; plus
(2) An additional five percent of the deficiency (or imputed underpayment) for each month (or fraction thereof) during which the failure continues, but not to exceed in the aggregate twenty-five percent of the deficiency (or imputed underpayment).
(c) Foreign tax redetermination defined. For purposes of this section, a foreign tax redetermination is any redetermination for which a notice is required under sections 905(c) or 404A(g)(2). See §§ 1.905-3 through 1.905-5 of this chapter for rules relating to the notice requirement under section 905(c).
(d) Reasonable cause. The penalty set forth in this section shall not apply if it is established to the satisfaction of the IRS that the failure to file the notification within the prescribed time was due to reasonable cause and not due to willful neglect. An affirmative showing of reasonable cause must be made in the form of a written statement that sets forth all the facts alleged as reasonable cause for the failure to file the notification on time and that contains a declaration by the taxpayer that the statement is made under the penalties of perjury. This statement must be filed with the Internal Revenue Service Center in which the notification was required to be filed. The taxpayer must file this statement with the notice required under section 905(c) or 404A(g)(2). If the taxpayer exercised ordinary business care and prudence and was nevertheless unable to file the notification within the prescribed time, then the delay will be considered to be due to reasonable cause and not willful neglect.
(e) Applicability date. This section applies to foreign tax redeterminations occurring in taxable years ending on or after December 16, 2019, and to foreign tax redeterminations of foreign corporations occurring in taxable years that end with or within a taxable year of a United States shareholder ending on or after December 16, 2019.
