401(k) Catch-Up Contributions in 2026, by Age

A catch-up contribution is the extra amount an older worker is allowed to put into a workplace retirement plan on top of the normal limit. It exists because the standard limit assumes a full career of saving, and plenty of people arrive at 50 without one.

For 2026 the ordinary elective deferral limit is $24,500. That is the most you can send from your own pay into a 401(k), 403(b), most 457(b) plans or the federal Thrift Savings Plan in a year. The catch-up sits on top of it, and since 2025 it comes in two sizes rather than one.

How much is the 401(k) catch-up in 2026?

From the calendar year in which you turn 50, you may contribute an extra $8,000. In the calendar years in which you are 60, 61, 62 or 63, that rises to $11,250. The larger figure is often called the super catch-up, and it is the change most people have not noticed.

Two things about that table surprise people. The first is that the super catch-up is temporary: it applies for four years and then stops. Somebody who turns 64 in 2026 does not keep the larger allowance, they go back to $8,000. The second is that age is measured by the calendar year, not your birthday. If you turn 50 on 30 December you can use the full catch-up for that entire year, including contributions made in January.

What is the super catch-up worth?

The extra $3,250 a year, for four years, is $13,000 of additional sheltered contributions. Its value is not the deposit though, it is the tax and the compounding.

Somebody in the 24% federal bracket who uses the full super catch-up for all four years defers $3,120 of federal income tax they would otherwise have paid, before any state tax. The money then grows untaxed until it is withdrawn.

Whether that is worth doing depends on the rate you avoid now against the rate you expect to pay later, which is the same question every pre-tax contribution asks. What is different here is the window. Most retirement decisions can be made next year instead. This one expires.

The Roth rule high earners keep missing

This is the part that generates the most confused searches, and the part most likely to affect what lands in your paycheck.

Under the SECURE 2.0 Act, catch-up contributions made by higher earners must be made as Roth contributions rather than pre-tax. Roth means the money is taxed on the way in and comes out untaxed later, which is the opposite of the usual catch-up treatment.

The test is based on your prior-year wages from the employer sponsoring the plan, and the threshold is indexed each year. Check the current figure against the IRS guidance on SECURE 2.0 catch-up contributions before you plan around it, because an indexed threshold moves and a stale one is worse than none.

Three consequences worth knowing:

• If the rule catches you, the catch-up portion stops reducing your taxable income. Your take-home pay falls even though your contribution has not changed.
• The rule applies only to the catch-up. Your first $24,500 can still be pre-tax if you want it to be.
• If your plan does not offer a Roth option at all, it cannot accept catch-up contributions from anybody the rule covers. A plan without a Roth feature is worth asking about now rather than in December.

Self-employment income does not count for this test, because the test looks at wages from the employer that sponsors the plan. A consultant with no W-2 wages from that employer is outside it.

Does the employer match count against the limit?

No, and this is the most common mistake in the whole subject. The $24,500 and the catch-up on top of it are limits on your own deferrals. What your employer puts in is counted separately, against a much higher combined limit on everything going into the account from all sources.

So a match does not eat into your catch-up, and a catch-up does not cost you any match. If your plan matches a percentage of pay rather than a percentage of your contribution, contributing more can leave the match unchanged. That is worth checking in the plan document rather than assuming, because the two designs behave very differently at high contribution levels.

How to actually get the money in

Catch-up contributions come out of payroll like any other deferral, which means the constraint is not the annual limit but the number of pay periods left in the year.

Somebody paid twice a month who decides in October to use the full $35,750 has five pay periods left. That is $7,150 per period, which for most people is more than the paycheck. The limit is not the problem, the calendar is.

If you want the full amount, set the election early in the year and spread it. If you are starting late, work backwards from your remaining pay periods and your take-home floor rather than from the limit, and use the 401(k) growth calculator to see what the smaller figure still does over time.

One further trap: some plans stop contributions the moment you hit the standard limit unless you have separately elected a catch-up. If your deferrals stop in November and you are over 50, that is usually why.

Is a catch-up contribution actually worth it for you?

The catch-up is an allowance, not advice. Three situations make it clearly worth using, and one makes it worth pausing.

Use it if you have unsheltered savings. Money sitting in a taxable brokerage account is being taxed on its dividends every year. Moving the equivalent amount into a 401(k) through payroll, and living on the taxable savings, converts taxed growth into sheltered growth without changing your spending at all. This is the single most effective use of a catch-up and the least understood, because it feels like saving more when it is really relocating what you already have.

Use it if you are in a high bracket now and expect a lower one later. A pre-tax contribution at 32% that comes out at 22% is a 10 point arbitrage on every dollar, before any growth.

Use it if your plan has good, cheap funds. A 401(k) with low-cost index options is a better home than most taxable alternatives.

Pause if you carry high-interest debt. No sheltered return reliably beats the certain return of clearing a balance charging 20% or more. Retirement money is also hard to reach without penalty, so it is the wrong place for anything you might need before 59 and a half.

The rules differ by plan type

The figures above are for 401(k), 403(b), most 457(b) plans and the federal Thrift Savings Plan, which share one elective deferral limit between them.

Two exceptions catch people out:

• A SIMPLE IRA has its own, lower limits, including a lower catch-up. If your employer runs a SIMPLE rather than a 401(k), none of the figures in this article apply to you.
• A governmental 457(b) has a separate limit from a 401(k) or 403(b). Somebody with access to both can contribute the full elective deferral to each, which is one of the few genuine ways to double the annual shelter. Public sector employees with a 403(b) and a 457(b) should check this rather than assuming one limit covers both.

If you change jobs mid-year, the limit follows you rather than the plan. Both employers' deferrals count against the same personal limit, and neither payroll system can see the other. Tracking the combined total yourself is the only way to avoid an excess.

What happens if you contribute too much

An excess deferral has to be corrected, and the deadline is tight. If you take the excess out, along with the earnings on it, by the correction deadline that follows the tax year, the excess is taxed as income for the year it was contributed and the matter ends there.

Miss the deadline and the money is taxed twice: once in the year of contribution and again when it eventually comes out of the plan. That is a genuinely bad outcome for an administrative slip, and it is why the two-employer case above is worth watching.

What this does not change

The catch-up raises how much you may put in. It changes nothing else.

• It does not raise the IRA contribution limit, which has its own separate catch-up.
• It does not change the tax brackets your income falls into. See the 2026 federal tax brackets for those.
• It does not reduce Social Security or Medicare tax. Pre-tax retirement contributions reduce income tax only, which is the same asymmetry that catches people out with bonus withholding.

That last point is worth stating plainly because it is the one people plan around incorrectly. A pre-tax 401(k) contribution lowers the income tax on your pay. The 6.2% and 1.45% still come out of the full amount.
