Catch-up contributions in 2026

The 2026 catch-up limits by age, why the 60–63 super catch-up replaces rather than stacks, and the new rule forcing high earners' catch-up into Roth.

Catch-up contributions are the one part of the tax code that rewards you for being late. If you are 50 or older, the law lets you put more into a 401(k) and an IRA than a younger colleague can — and for a narrow four-year window in your early sixties, more still. This spoke sits under the Retirement hub.

Two things changed for 2026, and both are being reported badly. The larger catch-up for ages 60–63 does not stack on the ordinary one, and high earners no longer get to choose whether their catch-up is pre-tax. Below is what the numbers actually are and what they mean for a person, not for an HR department.

The 2026 limits, by age

Your age for this purpose is the age you reach at any point during the calendar year. Turn 50 in December 2026 and you are catch-up eligible for the whole of 2026.

These are employee limits. They apply to 401(k), 403(b), governmental 457(b) and the federal TSP, and they are a single shared limit across all of them — two jobs with two 401(k)s does not mean two deferral limits. Employer contributions are separate and sit on top. Source: IRS Notice 2025-67.

The super catch-up replaces the standard one. It does not stack.

This is the error to burn into memory, because a great many pages that rank for this query get it wrong, and the mistake is expensive in both directions.

At ages 60 through 63, the catch-up is $11,250 instead of $8,000. Not in addition to it. Your ceiling at 61 is $35,750 — the base deferral plus one catch-up, the larger one.

Add the two catch-ups together and you get a number that does not exist in law. Someone who believes it will set a payroll deferral their plan refuses, or over-contributes and has to unwind an excess deferral before the filing deadline. The real gain from turning 60 is the difference between the two catch-ups — a useful sum, but much smaller than the stacked figure implies.

And it ends at 64

The larger catch-up is written for ages 60, 61, 62 and 63. In the year you turn 64 you go back to $8,000.

Nothing else in retirement law gives you something and then quietly takes it back while you are still working, which is why 60–63 is a window rather than a new baseline. Four years is real money, and it lands in exactly the years a household is most likely to be done with mortgages and tuition. If your plan is "I will max the big catch-up once I get there", check your cash flow can actually do it for four years — there is no extension.

The catch-up planner will show you which tier you fall into and how much room you have left this year.

The new rule: high earners must make the catch-up Roth

From 2026, SECURE 2.0 section 603 removes the pre-tax option for the catch-up portion for higher earners. If your prior-year Social Security (FICA) wages from the employer that sponsors your plan exceeded $150,000, every catch-up dollar you make in 2026 must be a designated Roth contribution. Pre-tax is not an option.

Your base $24,500 deferral is untouched. It can still be pre-tax. The rule bites only on the catch-up layer.

The threshold is not $145,000

$145,000 is the number written into the statute, and it is indexed. Notice 2025-67 set the amount for 2026 at $150,000, measured against your 2025 wages. Plenty of otherwise reputable pages, and a fair number of payroll memos, still quote the base figure. If your 2025 wages sat between those two numbers, the difference decides whether the rule applies to you at all.

Which wages, exactly

Four details that decide who is caught, and that the summaries tend to skip:

• Prior-year, not current-year. The 2026 test looks at 2025. A raise that lifts you over the line this year does not affect this year's catch-up; it affects next year's.
• FICA wages, not total income. The test is section 3121(a) wages — broadly, the Social Security wages in box 3 of your W-2. Not your household income, not your investment income, not your spouse's earnings.
• From that employer only. Wages from an unrelated employer are not counted. Change jobs and your new employer generally tests only what it paid you last year — which for a mid-year hire may be nothing. The final regulations do allow a plan to aggregate wages across certain related common-law employers, so a controlled group can be treated as one.
• No FICA wages means no rule. The test is a wage test. A partner or self-employed owner whose income is self-employment earnings rather than FICA wages has no section 3121(a) wages from the sponsor, so the mandate does not reach them however much they earn.

If your plan does not offer Roth, you may lose the catch-up entirely

This is the outcome nobody warns individual savers about. Under the final regulations, if a plan has no designated Roth program, a participant subject to the Roth catch-up requirement cannot make catch-up contributions at all. The plan is not required to add a Roth feature.

So a high earner in a plan without Roth does not fall back to a pre-tax catch-up. They lose the catch-up. If that is you, the practical response is to ask your plan administrator, this year, whether a Roth feature is coming — and in the meantime to route the money to an IRA or a taxable account rather than assume the payroll deduction will simply keep working.

2026 is a transition year

The statutory requirement applies from January 1, 2026. The final regulations generally apply to taxable years beginning after December 31, 2026, and for 2026 a plan may instead follow a reasonable, good-faith interpretation of the statute. The law binds now; the detailed rulebook binds next year. In between, two employers can land on mildly different answers at the edges — so do not assume your plan reads the wage test the way your last one did.

Many plans handle it with a deemed Roth election: if you are over the threshold, the plan treats your catch-up as Roth unless you say otherwise. The regulations require a real opportunity to elect differently — which in practice means declining the catch-up, not electing pre-tax. Read the notice your plan sends.

Whether a forced Roth catch-up is bad news is a separate question, and often it is not — see Roth vs Traditional. It costs a deduction today, buys a tax-free withdrawal later, and shrinks the pre-tax balance that will eventually drive your RMDs. What it does do is raise your taxable income now, which matters if you are managing income against ACA subsidies before 65.

The IRA is a separate bucket

The IRA limit is its own allowance, on top of the 401(k):

• IRA contribution limit: $7,500
• IRA catch-up at 50+: $1,100
• Maximum IRA contribution at 50 or older: $8,600

There is no super catch-up for IRAs. The $1,100 is the same at 51 as at 61.

Two limits before you assume the money goes where you want it. Direct Roth IRA contributions phase out at modified AGI of $153,000–$168,000 (single) and $242,000–$252,000 (joint). And if you are covered by a workplace plan, the deductibility of a traditional IRA contribution phases out at much lower incomes — you can still contribute, but the deduction may be gone.

The ceiling above your ceiling

There is a second limit most savers never meet: the total that can go into your 401(k) account from all sources in a year — your deferrals, the employer match, profit sharing, and any after-tax contributions. For 2026 it is $72,000.

The part worth knowing: catch-up contributions are not counted against it. They are not treated as annual additions, so your catch-up sits on top of the $72,000 ceiling rather than inside it.

That matters if your plan permits after-tax contributions and in-plan Roth conversions — the "mega-backdoor Roth". Your headroom for after-tax dollars is $72,000 minus your deferral minus everything your employer puts in, and the catch-up does not eat into it. Most plans do not offer the feature at all, so check before you plan around it.

One trap here. If your plan reclassifies excess pre-tax deferrals as catch-up contributions in order to use the full $72,000 allocation, and you are subject to the Roth catch-up mandate, those reclassified dollars have to end up as Roth — which produces a tax bill you did not plan for, in the year of the correction.

The Saver's Match arrives in 2027

If your income is modest, the more valuable change is one nobody is writing about.

For tax years after 2026, SECURE 2.0 section 103 replaces the Saver's Credit with the Saver's Match. The federal government contributes 50% of the first $2,000 you save — up to $1,000 a year — and, crucially, it is paid into your retirement account rather than deducted from the tax on your return. The old credit was non-refundable, which meant the people it was aimed at frequently owed too little tax to receive it. The match does not have that problem.

The statutory phase-out ranges are $20,500–$35,500 of modified AGI for single filers, $30,750–$53,250 for heads of household, and $41,000–$71,000 for joint filers, indexed after 2027. The match cannot be deposited into a Roth account, and the old credit's exclusions — dependents, full-time students, and under-18s — carry over. (Figures from the Senate Finance Committee's section-by-section summary. The IRS is still working through implementation, so the mechanics of how the money reaches your account may change.)

If you are 50-something, earning below those ceilings, and have been told catch-up contributions are the answer, this is the more consequential number. A guaranteed $1,000 into the account beats anything a fund selection will do for you.

Key takeaways

• The 2026 employee deferral is $24,500; the catch-up is $8,000 from 50, and $11,250 at ages 60–63.
• The super catch-up replaces the standard one. It never stacks. Your maximum at 61 is $35,750, and at 64 you drop back to $32,500.
• If your 2025 FICA wages from the plan sponsor exceeded $150,000, your 2026 catch-up must be Roth — and if the plan has no Roth feature, you cannot make one at all.
• Catch-ups do not count against the $72,000 total limit, which is what leaves room for a mega-backdoor Roth where a plan allows it.
• From 2027 the Saver's Credit becomes the Saver's Match: up to $1,000 paid into the account, not off the tax bill.

Work out your own number with the catch-up planner, or see where you stand overall with the Retirement Checkup. If you are starting late, starting retirement savings at 45 covers the levers that matter more than the limits do.
