Title 5 › Part III— EMPLOYEES › Subpart G— Insurance and Annuities › Chapter 84— FEDERAL EMPLOYEES’ RETIREMENT SYSTEM › Subchapter III— THRIFT SAVINGS PLAN › § 8440
Under the Internal Revenue Code, the Thrift Savings Fund is treated like a tax‑exempt retirement trust under section 401(a) and 501(a). Money put into or taken out of the Fund is handled the same way as contributions and distributions for that kind of trust. Because of limits in section 401(k)(4)(B) and section 402(a)(8), an employee’s choice to have pay go into the Fund instead of getting cash does not count as the money being paid out. Even if other laws say different, 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’s requirements. Putting basic pay into the Fund still counts as “wages” for Social Security (section 209 of the Social Security Act) and FICA (section 3121(a) of the Internal Revenue Code).
