Do employers match catch-up contributions? Usually not. Federal law lets them, but it doesn’t require them to, and most 401(k) plans are written so the employer match applies only to contributions within the standard deferral limit. Once you cross that limit and your catch-up dollars start going in, the matching formula typically stops. Whether your plan is one of the exceptions depends entirely on how the plan document is written.1Internal Revenue Service. 401(k) Resource Guide – Summary Plan Description
Why the Match Usually Stops at the Standard Limit
Federal law requires that if a plan offers catch-up contributions at all, every eligible participant age 50 or older must be allowed to make them. That’s the universal availability rule.2eCFR. 26 CFR 1.414(v)-1 – Catch-up Contributions The rule protects your right to defer the extra money. It says nothing about whether the employer has to add a matching contribution on top.
Most matching formulas are written around the standard deferral limit, which for 2026 is $24,500 for 401(k) plans.3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 A typical formula might match 50 cents on the dollar up to 6% of your salary. When you hit the $24,500 cap and your payroll system flips your remaining deferrals into the catch-up bucket, the match doesn’t follow. The employer’s obligation is already satisfied, and the catch-up money goes in unmatched. Workers over 50 often feel shortchanged by this, but the plan was never designed to match beyond the base limit in the first place.
If an employer does choose to match catch-up dollars, it has to apply the same rule to everyone. You can’t match catch-up for executives and skip it for rank-and-file employees without running into non-discrimination problems the IRS will flag.
The Three Ways a Plan Can Be Written
The plan document is the single authority. Verbal assurances from HR don’t override it. Your Summary Plan Description is required to explain how contributions are calculated and where the match stops.1Internal Revenue Service. 401(k) Resource Guide – Summary Plan Description Plans generally take one of three approaches:
- No match on catch-up. The employer match applies only to contributions within the standard $24,500 limit. Catch-up dollars go in entirely unmatched. This is the most common structure.
- Partial match. The formula extends into the catch-up range but caps at the same percentage or dollar amount used for regular deferrals.
- Full match. The employer keeps matching at the plan’s regular rate on catch-up contributions after the standard limit is exhausted. This is uncommon and significantly more expensive for the employer.
If your plan sits in the first category and you’d like that to change, the only path is through the plan sponsor amending the document. It’s a reasonable question to raise with HR, particularly at companies competing for experienced workers.
Safe Harbor Plans Follow the Same Rule
Safe harbor 401(k) plans commit to a specific matching formula in exchange for automatic pass on non-discrimination testing. A common safe harbor formula is dollar-for-dollar on the first 3% of salary and 50 cents on the dollar for the next 2%. Even in a safe harbor plan, matching catch-up contributions is still optional. The safe harbor commitment covers regular elective deferrals; extending it into catch-up territory is a separate decision in the plan document.
Employees in safe harbor plans sometimes assume the generous matching formula applies to everything they contribute. It doesn’t, unless the document says so explicitly. If you’re in a safe harbor plan and over 50, check the language before you build a savings strategy around continued matching.
Why Employers Avoid Matching Catch-Up
The main reason plans skip matching catch-up contributions has to do with annual non-discrimination testing. The Actual Contribution Percentage (ACP) test compares matching and after-tax contributions flowing to highly compensated employees against everyone else.4Internal Revenue Service. 401(k) Plan Fix-it Guide – The Plan Failed the 401(k) ADP and ACP Nondiscrimination Tests Catch-up deferrals themselves are carved out of the companion ADP test, but any employer match on those deferrals gets folded into the ACP calculation.5eCFR. 26 CFR 1.401(m)-2 – ACP Test
Highly compensated employees are the ones most likely to max out both regular and catch-up deferrals. Matching their catch-up pushes the highly compensated group’s average contribution rate higher. If the spread between the two groups gets too wide, the plan fails the test, and the employer has to either refund excess matching to highly paid employees or make additional contributions to bring the lower group’s average up. The added matching dollars are relatively small per person, but the compliance risk isn’t worth it for many plan sponsors.
The True-Up Wrinkle
Even when a plan does match catch-up, the way matching is calculated on each paycheck can shortchange you if you contribute unevenly. Say you front-load your deferrals and hit the annual maximum in September. From October through December you’re not deferring anything, which means no per-paycheck match either, even though your annual contributions would have entitled you to more matching dollars under the formula.
A true-up provision fixes this. Plans with a true-up compare your total annual contributions against the matching formula at year-end and deposit any shortfall, usually in the first quarter of the following year. Not every plan has one. If you routinely max out early and your plan does match catch-up, ask whether your plan trues up. The difference can run into hundreds or thousands of dollars a year.
How to Find Out What Your Plan Does
Start with the Summary Plan Description. Find the section describing employer matching contributions and read what it says about the deferral base the match applies to. If the language is ambiguous, call your plan’s recordkeeper — Fidelity, Vanguard, Empower, or whoever administers the account — and ask directly whether the employer match applies to catch-up contributions and whether the plan includes a true-up.
A few things won’t change the answer, even though they change how catch-up contributions work in 2026. The base catch-up limit rises to $8,000 for participants 50 and older, and workers ages 60 through 63 get a higher $11,250 limit under the SECURE 2.0 super catch-up.3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Employees earning more than $150,000 in FICA wages from the plan’s sponsoring employer in the prior year must make their catch-up contributions on a Roth basis starting in 2026.6eCFR. 26 CFR 1.414(v)-2 – Catch-up Contributions Required to Be Designated Roth Contributions None of that governs whether the employer matches. The Roth rule only changes how your catch-up deferrals are taxed. Any employer match on those deferrals, if the plan provides one, is always pre-tax regardless.
If it turns out your employer doesn’t match catch-up, making the contribution is almost always still worth it. You’re adding up to $8,000, or $11,250 in your early 60s, of tax-advantaged retirement savings each year. The match is a bonus when it exists. The tax treatment alone makes catch-up one of the strongest savings tools available to workers over 50.
