TSP and Retirement Guide: Planning Your Military Retirement Strategy
Military retirement planning can feel overwhelming because there are several moving parts: pension, TSP, savings, health benefits, and timing. For many service members, the biggest questions are not just "How much will I have?" but also "When should I start thinking about withdrawals or transition planning?"

TSP versus a 401(k)
The TSP is the federal government's defined-contribution plan and functions much like a 401(k). The difference is cost: TSP expense ratios are extremely low (often a few basis points), and the small number of core funds (G, F, C, S, I, and Lifecycle) makes allocation simple. For most service members, the TSP is the best place to invest at least the first 5% of pay, especially under BRS where the match is automatic.
Contribution strategy and the BRS match
If you are under BRS, the service contributes 1% automatically and matches up to 5% of your pay. Contributing less than 5% means leaving free money on the table. Many members split contributions between Traditional (pre-tax) and Roth (after-tax) to hedge against future tax-rate uncertainty. To see how contribution rate changes affect your final balance, run the numbers through our retirement calculator.

Withdrawal planning
How you withdraw from TSP affects your tax bill for decades. Common options include a lump sum, partial withdrawal, monthly installments, or rolling TSP into an IRA. Most planners recommend a partial rollover for flexibility, especially if you plan to use the TSP mutual fund window or want to invest beyond the core funds. Roth withdrawals are tax-free if you meet the 5-year rule.
Bottom line
A strong retirement plan is not just about the final number; it is about making decisions early enough to reduce stress later. Contribute at least 5% to capture the match, increase contributions when you can, and start thinking about withdrawal strategy 5-10 years before separation.
Frequently asked questions
What is the TSP?
The Thrift Savings Plan (TSP) is the federal government's defined-contribution retirement plan for service members and federal employees. It mirrors a 401(k) with the same tax advantages, but typically has lower expense ratios than most private-sector plans.
How much should I contribute to TSP?
Most planners recommend contributing at least 5% to capture the full BRS match. Contributing 10% to 15% balances lifestyle with strong long-term growth. The 2026 IRS elective deferral limit is $24,500, with a $7,500 catch-up if you are 50 or older.
What is the TSP match?
Under BRS, the government provides an automatic 1% contribution regardless of your own contribution, plus a dollar-for-dollar match on the first 3% and 50 cents on the dollar for the next 2%, for a total 5% match. Legacy members do not receive a match.
When can I withdraw from TSP?
You can withdraw from TSP after you separate from service, at age 59.5 (penalty-free), or at age 72 with required minimum distributions. Some financial hardships and in-service withdrawals are allowed under specific rules.
What are TSP withdrawal options?
At separation, you can take a lump sum, partial withdrawal, installment payments (fixed amount or duration), or annuitize through the TSP. Most financial planners recommend a partial withdrawal plus a rollover to an IRA for more flexibility.
What is the difference between Roth and Traditional TSP?
Traditional TSP contributions are pre-tax and taxed at withdrawal. Roth TSP contributions are after-tax and grow tax-free if you meet the 5-year rule. Many BRS members split contributions to hedge against future tax-rate uncertainty.
