BRS TSP Matching: What Happens to Government Contributions at Separation
Under the Blended Retirement System, the government matches TSP contributions after year 2. Here's how vesting works, what happens when you separate, and whether BRS helped or hurt you.
The Blended Retirement System (BRS), implemented for all new military entrants on January 1, 2018, includes a government TSP matching contribution that didn't exist under the legacy High-3 pension system. Understanding how this matching works at separation is essential for anyone who entered service after 2017.
How BRS TSP Matching Works
Under BRS, the government contributes to your TSP in two ways:
Automatic Contribution (1%): The government automatically contributes 1% of your base pay to your TSP starting in your second year of service, regardless of whether you contribute anything yourself. This happens automatically.
Matching Contributions: After two years of service, the government matches your TSP contributions dollar-for-dollar up to 3% of base pay, then 50 cents on the dollar for the next 2% of base pay.
The full benefit of the match requires you to contribute at least 5% of base pay:
- You contribute 5%
- Government contributes 1% automatic + 3% match + 1% (50% of your 4th and 5th percent) = 5% government contribution
- Total: 10% of base pay going to TSP (you contribute 5%, government 5%)
Vesting: When the Government Match Is Yours
Unlike your own contributions (which are always yours), government matching contributions vest on a schedule:
After 2 years: The automatic 1% contribution vests immediately at the 2-year mark (or upon death, disability, or retirement regardless of years served).
After 2 years: Matching contributions (not the automatic 1%) also vest after 2 years of service.
Practical result: If you complete two years of service under BRS, all government contributions are yours to keep when you separate.
If you separate before completing two years, government contributions that haven't vested are forfeited. You keep your own contributions plus earnings on all funds, but the unvested government match is returned to the government.
What Happens to the Match at Separation
When you separate, vested TSP matching contributions are already in your TSP account and belong to you. They are treated identically to your own contributions for all purposes:
- They remain in your TSP account
- They can be rolled over to an IRA or new employer's 401(k)
- They are subject to the same withdrawal rules and tax treatment as Traditional TSP funds
- They are subject to required minimum distribution rules

BRS vs Legacy: The Trade-Off
BRS replaced the legacy High-3 pension for post-2017 entrants. The trade-off:
Legacy High-3:
- No TSP matching
- 2.5% × years × average highest 3 years' base pay pension at 20 years
- Cliff vesting: nothing if you leave before 20 years
BRS:
- TSP matching (up to 5% with full participation)
- Reduced pension: 2.0% × years × average highest 3 years' base pay at 20 years
- Portable benefits for those who leave before 20 years
For service members who separate before 20 years: BRS is almost always financially superior because you leave with a TSP balance that includes government contributions. Under legacy, you left with nothing if you had fewer than 20 years.
For service members who serve 20+ years: BRS produces a smaller monthly pension than legacy (2.0% vs 2.5% multiplier), partially offset by the TSP balance built up over 20 years.
Not Contributing Enough to Get the Full Match
The most common BRS mistake: not contributing at least 5% of base pay to capture the full government match.
A service member contributing only 3% of base pay gets a 4% government contribution (1% automatic + 3% match). They're leaving 1% of base pay — free money — on the table every month.
At an E-5 pay grade with ~$3,000 base pay, that's $30/month in missed government match — $360/year, compounding over a career.
Check your current TSP contribution percentage at tsp.gov and verify you're at least at 5% if you're under BRS.
