Roth IRA vs TSP for Military: Where Should Your Money Go First?
Service members have access to two excellent retirement accounts — the TSP and a Roth IRA — and the order you fund them matters. For most members, the winning sequence is: TSP to the match, then a Roth IRA, then back to the TSP.
The priority order (for most members)
- TSP up to 5% — capture the full BRS match first. It's an instant 100% return; never skip it.
- Roth IRA up to the annual limit — broader investment choices and easier early access to contributions than the TSP.
- Back to the TSP — up to the elective limit ($24,500 in 2026), especially the ultra-low-cost index funds.
How they compare
| TSP | Roth IRA | |
|---|---|---|
| 2026 contribution limit | $24,500 (elective) | IRS IRA limit (separate) |
| Employer match | Up to 5% (BRS) | None |
| Investment choices | A handful of low-cost funds | Almost anything |
| Fees | Among the lowest anywhere | Varies by broker |
| Early access to contributions | Limited | Contributions withdrawable anytime |
The deployed-Roth superpower
In a combat zone, money you contribute to the Roth TSP goes in tax-free and comes out tax-free — and combat-zone months let you exceed the normal elective limit. Deploying is the single best time to max Roth contributions. See the combat-zone tax exclusion.
Junior members usually favor Roth (you're in a low tax bracket now); higher earners may split or lean Traditional. Either way, get the 5% TSP match first.

Should I use the TSP or a Roth IRA first?
Fund the TSP up to 5% first to capture the full BRS match, then a Roth IRA for broader choices, then return to the TSP up to the $24,500 elective limit.
Can I have both a TSP and a Roth IRA?
Yes — they have separate contribution limits, so you can fund both in the same year.
Why is Roth good for junior military members?
Junior members are usually in a low tax bracket, so paying tax now (Roth) and withdrawing tax-free later is often the better deal — especially with combat-zone Roth contributions.
