Title 5 › PART III — EMPLOYEES › Subpart G — Insurance and Annuities › CHAPTER 84 — FEDERAL EMPLOYEES’ RETIREMENT SYSTEM › SUBCHAPTER III — THRIFT SAVINGS PLAN › § 8440
Treat the Thrift Savings Fund as a tax‑exempt retirement trust under the Internal Revenue Code (sections 401(a) and 501(a)). Contributions and withdrawals are handled the same as for that kind of trust. If an employee chooses to have pay put into the Fund instead of receiving cash, that choice is not treated as a distribution or as the employee’s own contribution, subject to section 401(k)(4)(B) and any dollar limits in section 402(a)(8). The Fund does not have to follow the 401(k) nondiscrimination rules or the 401(m) matching rules so long as it meets this section. Any basic pay put into the Fund still counts as wages for Social Security (section 209) and for FICA (section 3121(a)).
