Open LES Tool→Under the Blended Retirement System (BRS), the government puts money into your Thrift Savings Plan, and that includes drilling Guard and Reserve members. Contribute 5% of your drill pay and the government adds up to 5% on top. Leaving that on the table is leaving free money behind.
BRS gives you an automatic 1% government contribution plus up to 4% in matching, for a total of 5% when you contribute at least 5% yourself. For Guard and Reserve members, this rides on your inactive-duty (drill) pay and your active-duty pay alike.
How the match works
The fine print
Contribute at least 5% of your drill pay. The government 5% is a 100% return before your investments earn a dime.
Drill pay is irregular, so check your LES and TSP statements to confirm the match is flowing. Set your contribution as a percentage so it scales with each drill and active-duty period. If you opted into BRS or joined after 2018, confirm your matching clock and election in MyPay.
For most younger members, a low-cost, age-appropriate Lifecycle (L) fund is a simple, diversified default. The point is less about picking funds and more about capturing the full match and letting time and compounding work across a long Guard or Reserve career.
Smart moves
Combat-zone pay into a Roth TSP goes in tax-free and comes out tax-free, a rare and powerful combo.

Do reservists really get a TSP match?
Yes, under BRS. The 1% automatic and up to 4% matching apply to drill (inactive-duty) pay and active-duty pay.
When does matching start?
After two years of service for members who entered on or after January 1, 2018. Those who opted into BRS got matching upon opting in.
How much should I contribute?
At least 5% to capture the full government match. More if you can.
Roth or traditional?
Roth TSP is attractive in low-income or combat-zone years; traditional lowers your taxable income now. Many split the difference.
