The Thrift Savings Plan

If you participated in the Uniformed Thrift Savings Plan while you were in the service, then you have several options:
*Tax-exempt contributions to the TSP are eligible for transfer to a traditional IRA or eligible employer plan only if the financial institution or plan will accept the funds. Funds not accepted will be paid directly to you. If you transfer balances from your uniformed service TSP account to your civilian TSP account, the TSP will not accept tax-exempt money.
