How TSP matching works

BRS service members (after 2 years of service) and FERS employees get the same formula: an automatic 1% of basic pay, plus a match of 100% on the first 3% they contribute and 50% on the next 2%. Your own contributions are limited to $24,500 in 2026, plus catch-up of $8,000 at age 50 or older, or $11,250 at ages 60 to 63.
