26 U.S.C. § 4974
Excise tax on certain accumulations in qualified retirement plans
If the amount distributed during the taxable year of the payee under any qualified retirement plan or any eligible deferred compensation plan (as defined in section 457(b)) is less than the minimum required distribution for such taxable year, there is hereby imposed a tax equal to 25 percent of the amount by which such minimum required distribution exceeds the actual amount distributed during the taxable year. The tax imposed by this section shall be paid by the payee.
For purposes of this section, the term “minimum required distribution” means the minimum amount required to be distributed during a taxable year under section 401(a)(9), 403(b)(10), 408(a)(6), 408(b)(3), or 457(d)(2), as the case may be, as determined under regulations prescribed by the Secretary.
