The Thrift Savings Plan (TSP) is a vital retirement savings and investment plan for federal employees and members of the uniformed services. Designed to resemble 401(k)-style plans found in the private sector, the TSP helps government workers build long-term retirement security with tax advantages and low fees.
What is the Thrift Savings Plan (TSP)?
The TSP is a defined contribution plan established by the Federal Employees’ Retirement System Act of 1986. It’s available to:
- Federal civilian employees
- Members of the uniformed services (active and reserve)
- Beneficiary participants
Participants can contribute a portion of their pay into individual TSP accounts, with the option for employer matching contributions in certain employment categories.
Key Features of the TSP

Participants can choose between:
- Traditional TSP: Contributions are pre-tax, reducing taxable income now; taxes are paid upon withdrawal.
- Roth TSP: Contributions are after-tax; qualified withdrawals are tax-free.
2. Employer Matching
FERS (Federal Employees Retirement System) employees receive:
- 1% automatic contribution
- Dollar-for-dollar match on the first 3% of salary contributed
- 50 cents per dollar for the next 2%
