Summary

Creates a Thrift Savings Fund inside the U.S. Treasury. The Fund is made up of all employee and agency contributions and certain deposits, plus investment gains or minus investment losses, and reduced by payments and expenses. The money in the Fund can be used at any time to invest, pay retirement or survivor benefits and buy annuities, cover administrative costs, make certain distributions, make authorized loans to employees or members, and buy insurance. Administrative costs must be paid first from forfeited amounts in the Fund and then from the Fund’s investment earnings. Account balances must be used only for the benefit of the worker or their beneficiaries and generally cannot be assigned or seized. Exceptions include child support, alimony, court-ordered restitution, certain required transfers or forfeitures, and federal tax levies. All contributions and their net earnings are held in trust for the worker.
