26 U.S.C. § 4979
Tax on certain excess contributions
The tax imposed by subsection (a) shall be paid by the employer.
For purposes of this section, the term “excess contributions” has the meaning given such term by sections 401(k)(8)(B), 408(k)(6)(C), and 501(c)(18).
For purposes of this section, the term “excess aggregate contribution” has the meaning given to such term by section 401(m)(6)(B). For purposes of determining excess aggregate contributions under an annuity contract described in section 403(b), such contract shall be treated as a plan described in subsection (e)(1).
No tax shall be imposed under this section on any excess contribution or excess aggregate contribution, as the case may be, to the extent such contribution (together with any income allocable thereto through the end of the plan year for which the contribution was made) is distributed (or, if forfeitable, is forfeited) before the close of the first 2½ months (6 months in the case of an excess contribution or excess aggregate contribution to an eligible automatic contribution arrangement (as defined in section 414(w)(3))) of the following plan year.
Any amount distributed as provided in paragraph (1) shall be treated as earned and received by the recipient in the recipient’s taxable year in which such distributions were made.
