2026 401(k) Catch-Up Contribution Rule Changes for Highly Compensated Employees: What You Need to Know
If you're a high earner planning for retirement, you may need to update your 401(k) strategy soon. Beginning in 2026, a key change is set to impact how highly compensated employees (HCEs) make catch-up contributions to their 401(k) plans — and it's essential you’re prepared.
Here’s a breakdown of what’s changing, who’s affected, and how to adjust your savings plan accordingly.
Under the SECURE 2.0 Act, originally passed in December 2022, individuals aged 50 and older are allowed to make catch-up contributions beyond the standard 401(k) contribution limits. However, starting in 2026 (delayed from the original 2024 effective date due to IRS transition relief), high earners will face a significant new requirement:
If you earned more than $145,000 in the prior year (2025), all catch-up contributions to a 401(k), 403(b), or governmental 457(b) plan must be made on a Roth (after-tax) basis.
This means:
- No more pre-tax catch-up contributions for HCEs.
- All catch-up dollars will be taxed now but grow tax-free for retirement.
The rule targets individuals earning more than $145,000 in the previous calendar year (indexed for inflation, so this number may rise in 2026). This applies per employer, so compensation from other jobs won’t count unless it's the same company.
In short:
- Age 50 or older
- Earned over $145,000 in 2025 from your employer
- Planning to make catch-up contributions in 2026?
Then this rule applies to you.
If you were relying on the tax break from pre-tax catch-up contributions, this rule change could require a budgeting adjustment.
Here’s a quick checklist to prepare for 2026:
- Check your 2025 income. Will you earn more than $145,000 from your employer? If so, expect the Roth requirement.
- Review your plan’s Roth option. Not all 401(k)s currently allow Roth contributions — but they’ll need to by 2026 if catch-up contributions are offered.
- Talk to HR or your plan provider. Confirm your plan is updating for compliance.
- Adjust your tax planning. Consider how increased taxable income in 2026 could impact your tax bracket.
- Meet with a financial advisor. They can help optimize your strategy for Roth contributions and future withdrawals.
