Does Employer Match Count Toward Your 401(k) Limit? (2026)

There are two 401(k) limits and most people have only heard of one. Every page ranking for this question gives the reassurance in the first line and stops there, which leaves the reader never learning that a second ceiling exists or how much room sits under it.

Limit one: what comes out of your pay

$24,500 for 2026. That is the elective deferral limit under section 402(g), and it covers only money you defer yourself.

Pre-tax and Roth deferrals share it. Splitting your contributions between a Roth 401(k) and a traditional one does not give you two allowances, it divides one, and that misunderstanding is common enough to be worth stating plainly.

It is also a limit on you rather than on a plan. Two jobs in one year means two payroll systems, each tracking only its own deferrals, and the aggregate is your responsibility. More on that below, because it is the commonest way people breach a limit without meaning to.

One trap at the other end: if your plan matches per pay period and does not run a year-end true-up, hitting the deferral limit in September leaves nothing to match for the rest of the year. Front-loading can cost you match dollars. Whether your plan trues up is in the plan document.

Limit two: everything that lands in the account

$72,000 for 2026, under section 415(c). It covers your deferrals, the employer match, profit-sharing and any after-tax contributions, combined.

The gap is $47,500. Whether any of it gets used is decided by your employer's plan design rather than by you, which is why reading the overall ceiling as a personal target is the most common misreading of these numbers.

One more figure shapes it: the annual compensation limit is $360,000 for 2026, so a plan cannot count pay above that when working out contributions. A match expressed as a percentage of salary stops growing there however much you earn.

Which ceiling does each kind of dollar hit?

Six kinds of money can land in a 401(k) in a year. This is where each one counts, who decides whether it happens, and whose problem it is if a ceiling is breached.

Set membership from IRS Notice 2025-67 and the IRS 401(k) contribution limits guidance, read September 2026. No cell is a dollar amount, because this table sorts kinds of money rather than measuring them.

What the gap is actually for

Employer money fills most of it. What fills the rest, in the minority of plans that permit it, is after-tax contributions.

An after-tax contribution is not a Roth deferral. It goes in with no deduction and, left alone, only its growth is taxed on the way out. Converting it to Roth inside the plan is what people mean by the mega-backdoor Roth, and the name makes it sound like a strategy you can choose.

It is a plan feature, not a choice. Your plan has to permit after-tax contributions and it has to permit in-plan conversions or withdrawals, and most plans permit neither. Before you read another word about it anywhere, open your own plan document and look for both. If either is missing, the mechanism is not available to you and no amount of planning changes that.

Catch-up contributions sit outside both

From age 50 you can add $8,000 on top, and between 60 and 63 it is $11,250 instead.

Neither counts against the deferral limit or the overall ceiling, which is why the IRS states the practical total reaches $80,000 from 50 and $83,250 between 60 and 63. SECURE 2.0 also requires catch-up contributions to be made as Roth for employees whose prior-year wages from that employer exceeded an indexed threshold, so check the current figure with the IRS rather than assuming your catch-up is pre-tax.

The four-year window between 60 and 63 is worth planning around, and our guide to the 2026 limits works through what it is worth. This page owns what counts toward the ceilings; that one owns the numbers themselves.

Which limit is your problem?

The deferral limit is yours. The overall ceiling is the plan administrator's. That distinction is the most useful thing on this page.

Breaching the deferral limit is usually the reader's own doing, and changing jobs mid-year is how. Each employer's payroll tracks its own plan and neither sees the other, so two plans can each be within their own limits while your personal total is over. Nobody is adding them up but you.

If it happens, there is a deadline. Tell your plan administrator before April 15 of the following year and ask for the excess, adjusted for earnings, to be distributed to you. The IRS is blunt about missing it: an excess deferral left in the plan is taxed twice, once when contributed and again when distributed.

An excess annual addition, by contrast, is a plan qualification issue and the administrator corrects it. You do not need to do anything, and in practice you will rarely encounter one.

Roth 401(k), solo 401(k), two jobs

Three variants that change the answer, and one that does not.

• Roth 401(k). Same deferral limit, shared with pre-tax. Which to use is a different question, and the Roth versus traditional calculator works it through.
• Solo 401(k). You are both the employee and the employer, so you make a deferral and an employer contribution, and both ceilings apply as usual.
• Two jobs. The deferral limit is one ceiling across every plan you participate in. The overall ceiling generally applies per employer, which is why the two failures have different owners.

A pre-tax deferral also reduces state taxable income in most states, though a few treat retirement contributions differently from the federal rule, so it is worth checking your own state.

Work out your own room

Take the deferral limit, subtract what you have already deferred this year across every employer, and that is what you can still put in from pay. The employer side is not yours to plan. Project the balance forward once you know the number.
