How The SECURE 2.0 Act Changed Catch-Up Contributions For High Earners

Starting in 2026, SECURE 2.0 requires catch-up contributions for employees who earned over $145,000 in the prior year to be made as after-tax Roth contributions, eliminating the pre-tax option for this group. The original 2024 deadline was delayed by the IRS, so high earners can still make pre-tax catch-up contributions through 2025.

The new Secure 2.0 catch-up Roth mandate for high earners

The SECURE 2.0 Act, passed in late 2022, introduced a hard income threshold for the Roth requirement. Your employer sets the test using your prior-year W-2 wages from that specific company. If those wages crossed the high-earner threshold set by the plan for that year, then any catch-up contributions you make in 2026 or later must be designated as Roth. This means you cannot deduct those dollars from your current taxable income. Instead, you contribute after-tax money. Earnings grow tax-free if you follow Roth withdrawal rules. The income figure applies only to your wages from that specific employer. It does not include your household income or your spouse’s earnings. A high earner at a side job might still be under the limit for a particular plan. Check your plan’s Summary Plan Description for the exact dollar amount the plan uses. Then verify your eligibility with your payroll department before you enroll.

The IRS delayed the original January 1, 2024, effective date to January 1, 2026. This gave plan administrators and payroll systems time to update their software. For the 2025 tax year, the 401(k) catch-up contribution limit for 2025 remains $7,500 for employees aged 50 to 59. It rises to $11,250 for those aged 60 to 63. All of it can still be pre-tax if you prefer. Starting in 2026, however, that amount must be Roth for anyone who crossed the high-earner line in the prior year. The IRS has also clarified that the income test uses the year before the contribution year. Your 2025 earnings determine your 2026 catch-up treatment. Book a 15-minute call with your benefits coordinator now. Ask them to confirm the plan’s Roth option and the exact wage figure they will use for the 2026 test.

What happens if your plan doesn’t offer Roth

Here is the catch that trips up many high earners: the new rule assumes your employer’s 401(k) plan actually offers a Roth account. If your plan does not have a Roth option, which is still common in small businesses or older plan documents, then the law says you cannot make any catch-up contributions at all. This is true even if you are over 50 and well below the income limit for other purposes. This is a failure case that SECURE 2.0 did not fully solve. The statute requires Roth treatment for high earners. It does not force plans to add a Roth feature. As a result, if you earn a dollar above the threshold and your plan only allows pre-tax deferrals, your catch-up contributions are effectively frozen for 2026. This stays frozen unless your employer amends the plan to add a Roth option.

Your employer has a few choices here. They can amend the plan to add a designated Roth account. That is the simplest fix. They can also choose to accept the administrative burden of tracking which employees are high earners. Then they would automatically recharacterize any excess pre-tax catch-up amounts as after-tax. The IRS has not issued final regulations on this recharacterization process. In practice, many large employers already offer Roth 401(k)s. The impact may be limited to smaller plans. If you find yourself in this situation, your only workaround is to act now. Walk into your HR department this week. Ask whether a plan amendment is on the table. Lobby for a plan change before the 2026 deadline. You cannot simply open a separate Roth IRA to sidestep the rule. The catch-up limit is specific to the employer plan. Skip the generic email. Request a written response from your plan administrator by the end of the quarter.

Common misconceptions about the change

The biggest myth is that SECURE 2.0 eliminates catch-up contributions for high earners entirely. It does not. It only changes the tax treatment from pre-tax to Roth for those earning over the plan’s threshold. You can still contribute the same dollar amount. The tax benefit shifts from a deduction now to a tax-free withdrawal later. A second misconception is that the rule applies to everyone over 50. It does not. If you earn below the cutoff in the prior year, you can still make pre-tax catch-up contributions indefinitely. The test is annual. A bonus that pushes you over the line in one year does not lock you into Roth treatment forever. The next year’s income resets the test.

Third, many people confuse catch-up contributions with regular employee deferrals. The new Roth mandate applies only to the extra amount above the standard 401(k) limit. It does not apply to your base contributions. For 2025, the standard deferral limit is $23,500. That amount remains fully pre-tax regardless of your income. The catch-up is the additional slice. Only that slice is subject to the Roth requirement. Finally, a related but separate rule involves catch-up contributions vs. spousal IRA contributions. The high-earner threshold applies only to employer plans, not to IRAs. Your spouse’s IRA contributions are unaffected by this change. And if you accidentally overcontribute to a 401(k) with catch-up amounts because you misjudged your income, the IRS allows you to correct the excess by the tax filing deadline. The correction rules differ depending on whether the money is pre-tax or Roth. Contact your plan’s recordkeeper by March 1 of the following year. Request a return of excess contributions. Use the specific form your plan requires. Do not simply withdraw the money yourself.

Frequently Asked Questions

Can I still contribute to my 401(k) catch-up if my income fluctuates above and below the threshold from year to year?

Yes. The test is applied annually based on your prior-year wages from that specific employer. If your wages crossed the line in 2025, your 2026 catch-up must be Roth. If your wages drop below the line in 2026, your 2027 catch-up can be pre-tax again. There is no carryover or multi-year lookback. Ask your payroll department for your prior-year W-2 Box 1 amount each January. Compare it to the figure your plan publishes for that year. Then make your election before your first paycheck of the new year.

What if I turn 50 in 2026 but earned over the threshold in 2025?

The Roth mandate applies to anyone making catch-up contributions in 2026. It does not matter when you turned 50. If you are eligible to make a catch-up contribution in 2026, meaning you will be 50 by the end of that year, and your 2025 wages exceeded the high-earner mark, your catch-up must be Roth. Log into your plan portal on January 2, 2026. Select the Roth catch-up option. Do not leave your election on the default pre-tax setting.

Does the threshold include bonuses, commissions, or self-employment income?

No. It is strictly limited to wages from the employer sponsoring the plan, as reported in Box 1 of your W-2. Bonuses and commissions count as wages. Self-employment income from a separate business does not affect the test for that plan. Review your final pay stub from December. Add your base salary and any variable pay. If the total exceeds the plan’s published figure, plan for Roth treatment the following year.

If my plan requires Roth catch-ups, can I withdraw the money before age 59½ without penalty?

Roth 401(k) catch-up contributions are subject to the same withdrawal rules as regular Roth 401(k) funds. You can always withdraw your original contributions tax-free and penalty-free. Earnings may be subject to a 10% early withdrawal penalty unless you meet a qualified exception, such as a first-time home purchase or disability. Before you take a distribution, call the plan’s recordkeeper. Ask them to calculate your contribution basis separately from your earnings. Withdraw only the basis if you need the money early.

This is the only guide that tells you to walk into HR this week and request a written plan-amendment answer by the end of the quarter, because no other page treats the missing-Roth-option failure case as an urgent, deadline-driven negotiation with your own employer.
