The Thrift Savings Plan

The Thrift Savings Plan (TSP) is the government's version of the popular 401(k) plan.  Contributions are made from pre-tax dollars and investment earnings are tax deferred until withdrawn.

FERS employees are allowed to invest up to a threshold set annually by the IRS ($15,500 in 2008).  Your agency will automatically contribute an amount equal to 1 percent of your basic pay each pay period and matches your contributions according to the following schedule:

Percent of Basic Pay Contributed to Your Account (FERS Employees Only)
You put in: Agency's Automatic (1%) Contribution Agency Matching Contribution And the total contribution is:
0% 1% 0% 1%
1% 1% 1% 3%
2% 1% 2% 5%
3% 1% 3% 7%
4% 1% 3.5% 8.5%
5% 1% 4% 10%
NOTE: Amounts that you contribute over 5% are not matched.

There is a one year waiting period before newly hired FERS employees receive agency contributions.  At any time you can begin investments, change the amount of investment, or change the allocation of how much money you have going into each of the TSP's investment funds.  You also can move your account balances among the funds, whenever you choose, through inter-fund transfers.
