The short answer: it depends on your plan
The IRS does not require employers to match catch-up contributions. Whether your employer matches them is a plan design choice — some do, some don't. There's no rule that says they have to extend the match to catch-up contributions just because they match regular contributions.
How most plans handle it
In practice, most employer match formulas are based on a percentage of your compensation — not a fixed dollar amount. Because catch-up contributions are contributions of your own money, they technically fall into the same category as your regular contributions from the employer's math perspective.
Here's how it typically works:
- If your plan matches "50% of contributions up to 6% of salary," the match is calculated on your salary, capped at 6%
- Once you've contributed 6% of salary and received the full match, any additional contributions — including catch-up contributions — are yours alone, with no employer match
- In this case, your catch-up contributions beyond the 6% threshold get no employer match — not because you're over 50, but because you've already passed the match cap
Key insight: Most employees who make catch-up contributions have already exceeded the match threshold with their regular contributions. The catch-up contributions go beyond the match cap, so there's nothing to match — regardless of age.
When employers DO match catch-up contributions
Some plans — particularly very generous ones at large employers — match all contributions up to the IRS annual limit, including catch-up amounts. In these cases, an employee aged 50+ who contributes $31,000 might receive a match on the entire $31,000 rather than just the $23,500 regular limit. This is relatively uncommon but worth checking in your plan documents.
The 2026 rule change: Roth catch-up contributions
Starting in 2026 (delayed from 2024), employees earning more than $145,000 in the prior year are required to make catch-up contributions as Roth (after-tax) rather than pre-tax. This is a SECURE 2.0 requirement. Employer matching contributions, however, always go into the traditional (pre-tax) side of the account regardless of whether your catch-up contributions are Roth.
How to check your specific plan
The clearest answer is in your Summary Plan Description (SPD) under the section on employer contributions. Look for language like "matching contributions are calculated on eligible compensation" or "the match applies to elective deferrals up to X%." If the match formula is based on a percentage of compensation, catch-up contributions beyond the threshold won't be matched.
When in doubt, ask HR directly: "Does the employer match apply to catch-up contributions, or only to contributions up to the match threshold?"
| Scenario | Employer matches catch-up? |
|---|---|
| Match capped at 6% of salary; you contribute 10% (including catch-up) | No — match already capped at 6% |
| Match on all contributions up to IRS limit | Yes — catch-up gets matched too |
| Dollar-for-dollar match with no percentage cap | Rarely — most plans still have a cap |
