26 CFR § 301.6511(f)-1 - Special rules for chapter 42 taxes.

§ 301.6511(f)-1 Special rules for chapter 42 taxes.

(a) In general. Claims for credit or refund of an overpayment of any tax imposed by chapter 42 shall be filed by the taxpayer within 3 years from the time a return was filed by the private foundation or trust (as the case may be) with respect to such tax, or within 2 years from the time the tax was paid, whichever of such periods expire the later.

(b) Examples. This section may be illustrated by the following examples:

Example 1.
In 1972, D, an individual taxpayer who was a disqualified person under the provisions of section 4946(a)(1), participated in an act of self-dealing with a private foundation and incurred a tax under section 4941(a)(1). The private foundation files a Form 990-PF on May 15, 1973, and discloses thereon that it has engaged in an act of self-dealing with D. D files a Form 4720 on July 2, 1973, and pays the amount of tax imposed by section 4941(a) with respect to such act of self-dealing. For purposes of this section, the return was filed on May 15, 1973, and any claim for credit or refund by D must be filed by May 17, 1976 (May 15, 1976, was a Saturday).
Example 2.
Assume the same facts as in example 1 except that D filed a Form 4720 on July 1, 1974, and pays the tax on that date. D must then file any claim for credit or refund by July 1, 1976.
