Should I max out my TSP before contributing to a Roth IRA?

Usually not. The right order is to contribute enough to the TSP to capture the full agency match (5 percent of pay), then fund a Roth IRA up to its limit, and only then go back and max out the TSP. The match is free money and comes first. But once you have it, a Roth IRA generally beats extra TSP dollars because it offers far more investment choice and, for many people, valuable tax diversification. Maxing the TSP first skips over the Roth IRA step and gives up that flexibility.

What is the full agency match on the TSP?

For FERS employees, the agency automatically contributes 1 percent of your basic pay whether or not you contribute anything. On top of that, it matches your own contributions dollar-for-dollar on the first 3 percent and 50 cents on the dollar for the next 2 percent. Contribute 5 percent of your pay and you receive the full 5 percent agency contribution, so 10 percent of pay flows into your TSP. That first 5 percent is the highest-return money you will ever invest.

What are the 2026 TSP and IRA contribution limits?

For 2026 the TSP elective-deferral limit is $24,500. Employees age 50 and older can add an $8,000 catch-up (a total of $32,500), and those age 60 to 63 can make a larger super catch-up of $11,250 (a total of $35,750). The IRA contribution limit for 2026 is $7,500, or $8,600 if you are 50 or older. Note that beginning in 2026, if your prior-year FICA wages exceeded $150,000, your TSP catch-up contributions must be made as Roth.

Why is a Roth IRA better than extra TSP contributions?

Two reasons. First, choice: the TSP offers a handful of low-cost funds, while a Roth IRA lets you invest in essentially any fund, stock, or ETF you want. Second, taxes and access: Roth IRA contributions can be withdrawn at any time without tax or penalty, and qualified growth comes out tax-free, giving you a flexible, tax-free bucket that complements the mostly traditional balances of a typical federal saver. The TSP's low fees are excellent, so you still max it after the Roth IRA — the Roth IRA just deserves priority for the flexibility it adds.

Does it matter when during the year I contribute to the TSP?

Yes. The agency match is calculated each pay period, not annually. If you front-load and hit the $24,500 limit before December, your contributions stop for the rest of the year and so does the match on those pay periods — you can lose free money. To capture the full match, spread your contributions so you are putting in at least 5 percent of pay in every pay period through the end of the year.

Why maxing the TSP first can be a mistake

“Max out the TSP” is the standard advice — and for the first 5% of your pay it’s exactly right. But pouring every extra dollar into the TSP before you fund a Roth IRA skips a better step. Here’s the order that captures every dollar of free money, then builds the flexibility a mostly-traditional federal saver needs.

The flexibility gap

1. The mistake hiding inside good advice

“Max out your TSP” is repeated so often it sounds like the whole answer. It isn’t. The TSP is a genuinely excellent plan — rock-bottom fees, a generous match — but treating “more TSP” as the automatic home for every spare dollar quietly skips a step that would leave you better off.

The issue isn’t that the TSP is bad. It’s that not all retirement dollars are equal. The first 5% you contribute is the best investment you’ll ever make. The dollars after the match, though, are competing with a Roth IRA — and for most federal savers, the Roth IRA wins that particular round. Maxing the TSP first jumps straight past it.

2. The right order, in one table

Here is the priority order for every dollar of retirement savings, best return first.

The order to fund a federal retirement
Priority	Where the dollar goes	Why
1st	TSP up to 5%	Captures the full agency match — an instant 100% return you can’t get anywhere else
2nd	High-interest debt	Paying off a 20% card is a guaranteed 20% return — better than any market bet
3rd	Roth IRA (to the max)	Full investment freedom and a flexible, tax-free bucket the TSP can’t match
4th	Max the TSP	Now fill it up — the low fees make it the best home for large balances
5th	HSA / taxable brokerage	An HSA (if eligible) is triple-tax-advantaged; a brokerage adds flexible, no-limit savings

Notice where “max the TSP” actually sits: fourth, not first. It’s a great step — just not the next step after the match.

3. Step 1: Capture the full match

Before anything else, contribute enough to grab every dollar of the agency match. For FERS employees the structure is:

How the FERS agency contribution works
Your contribution	Agency adds	Running total into your TSP
0%	1% (automatic)	1%
First 3%	+3% (dollar-for-dollar)	7%
Next 2%	+1% (50 cents on the dollar)	10%

Contribute 5% and 10% of your pay lands in your account. That first 5% earns an immediate 100% return before a single market gain — nothing else in personal finance comes close. Skipping it to do anything else is the one true mistake.

Don’t leave the match on the table

If high-interest debt is crushing you, still contribute the 5% to grab the match first — then attack the debt. Turning down a guaranteed 100% match to pay a 20% debt is math working against you.

4. Step 2: Then the Roth IRA — here’s why

Once the match is secured (and any high-interest debt is handled), the next dollar should usually go to a Roth IRA — up to $7,500 in 2026, or $8,600 if you’re 50 or older — before you go back to the TSP. Two reasons:

Investment freedom. The TSP gives you five core funds plus lifecycle options. That simplicity is a feature, but it’s also a ceiling. A Roth IRA at any brokerage lets you hold essentially any low-cost index fund, sector, or ETF you want.

Tax diversification and access. Most federal savers are heavy in traditional (pre-tax) balances, because the agency match always goes to traditional and many contribute traditional too. A Roth IRA builds a genuinely tax-free bucket for retirement — and your Roth IRA contributions can be pulled out any time, tax- and penalty-free, giving you an emergency backstop the TSP doesn’t offer.

The match is about return. The Roth IRA is about flexibility and tax mix. You want both — which is exactly why the Roth IRA belongs between the match and maxing the TSP, not skipped over.

5. Step 3: Now max the TSP

After the Roth IRA is full, come back and max the TSP toward the $24,500 2026 limit (plus the $8,000 catch-up at 50+, or the $11,250 super catch-up at 60–63). This is where the TSP shines: its expense ratios are among the lowest in the world, so it’s the ideal home for large, long-term balances. You’re not avoiding the TSP — you’re just funding it in the right sequence.

One 2026 wrinkle: if your prior-year FICA wages topped $150,000, your catch-up contributions now have to be made as Roth. That’s a SECURE 2.0 rule, and for most affected feds it’s a mild positive — more tax-free money.

6. The front-loading trap

One more mistake worth naming, because it costs real money: front-loading. The agency match is calculated each pay period. If you contribute so aggressively that you hit the $24,500 limit in, say, October, your contributions stop for the rest of the year — and so does the match on those final pay periods. You can lose hundreds or thousands in free money by finishing too early.

The fix

Spread contributions so you’re putting in at least 5% of pay every pay period through December. Divide the annual limit by your number of pay periods (usually 26) to find the per-period amount that finishes in the last paycheck — not before.

7. FAQ

Should I max out my TSP before a Roth IRA?

Usually not. Contribute 5% to the TSP to grab the full match, then max the Roth IRA, then go back and max the TSP. The match comes first because it’s free money; the Roth IRA comes next because it adds investment freedom and tax diversification that extra TSP dollars don’t.

What is the full agency match?

FERS employees get an automatic 1% plus a match: dollar-for-dollar on the first 3% and 50 cents on the next 2%. Contribute 5% and you get the full 5% agency contribution — 10% of pay total. The first 5% is a 100% return.

What are the 2026 limits?

TSP elective deferral: $24,500. Catch-up (50+): $8,000, for $32,500. Super catch-up (60–63): $11,250, for $35,750. Roth IRA: $7,500, or $8,600 at 50+. If prior-year FICA wages exceeded $150,000, TSP catch-up must be Roth in 2026.

Why is a Roth IRA better than extra TSP?

Choice and flexibility. The TSP has five funds; a Roth IRA can hold nearly anything. Roth IRA contributions can be withdrawn anytime tax- and penalty-free, and qualified growth is tax-free — a flexible bucket that balances a federal saver’s mostly-traditional balances. You still max the TSP afterward for its low fees.

Does contribution timing matter?

Yes. The match is per pay period. Front-load and hit the limit early, and the match stops on the remaining pay periods. Spread contributions so you hit the limit in the final paycheck, not before.
