A significant change under the SECURE 2.0 Act takes effect in 2026 that directly impacts high-earning workers approaching retirement. Employees aged 50 and over who earned more than $150,000 in the previous year must now make any catch-up contributions to employer-sponsored retirement plans, such as 401(k)s and 403(b)s, on a Roth (after-tax) basis. Pre-tax catch-up contributions are no longer available for this group.
The change does not eliminate catch-up contributions. It changes the tax treatment. For workers who have relied on pre-tax catch-up contributions to reduce their current taxable income, the shift requires rethinking their retirement savings strategy and tax planning approach.
Key Changes for 2026
- Workers 50+ earning over $150,000 must make catch-up contributions as Roth
- The $150,000 threshold is based on prior year (2025) FICA wages
- Standard catch-up contribution limit for 50+: $8,000
- Super catch-up for ages 60-63: up to $11,250 (if plan adopts)
- Regular 401(k) contribution limit: $24,500 (unchanged)
- IRA catch-up contributions ($1,100) are NOT affected by this rule
Why the Government Made This Change
The Congressional Budget Office estimated that high-earning workers using pre-tax catch-up contributions cost the federal government approximately $1.8 billion per year in deferred tax revenue. By mandating Roth treatment, the government collects income tax on catch-up contributions immediately rather than waiting until retirement withdrawals. This front-loads tax revenue, helping to offset the costs of other SECURE 2.0 provisions.
For workers affected by this change, the immediate impact is a higher tax bill. An employee earningn $200,000 in the 32% federal bracket who contributes $8,000 in catch-up contributions will pay approximately $2,560 more in federal income tax in 2026 compared to the pre-tax option. Add state income tax, and the cost rises further in high-tax states.
"The Roth catch-up mandate is a stealth tax increase dressed up as retirement policy," said Ed Slott, CPA and IRA expert. "Workers affected by this change are not losing the ability to save more, but they are losing the tax deduction they relied on. The long-term math favors Roth contributions for most people, but the annual cash flow impact is real."
Is Roth Actually Better for You?
Roth contributions grow tax-free, and withdrawals in retirement are also tax-free. If you expect your tax rate in retirement to be equal to or higher than your current rate, Roth treatment is mathematically superior. Most financial planners believe tax rates will rise over the next 20-30 years due to federal debt levels, Social Security funding shortfalls, and political dynamics. Under that assumption, paying taxes now at known rates is preferable to paying unknown (and likely higher) rates later.
However, if you expect a significantly lower tax rate in retirement, perhaps because you plan to retire to a no-income-tax state or will have substantially lower income, the pre-tax option would have been more valuable. This calculation depends on your individual circumstances.
Action Steps for Affected Workers
Review your 2025 W-2 box 3 (Social Security wages) or box 5 (Medicare wages) to determine if you exceeded the $150,000 threshold. If so, contact your HR department or plan administrator to confirm that your catch-up contributions are being directed to the Roth bucket automatically. Adjust your withholding if needed to account for the higher current-year tax liability.
Consider increasing your regular pre-tax 401(k) contributions to the $24,500 limit if you have not already maxed them out. Pre-tax treatment is still available for the standard contribution. The Roth mandate applies only to the catch-up portion. Balance your overall tax strategy by using pre-tax for the first $24,500 and Roth for the catch-up, creating diversified tax treatment in your retirement portfolio.
The Super Catch-Up Opportunity
Workers aged 60 through 63 may contribute up to $11,250 in catch-up contributions (instead of $8,000) if their employer's plan has adopted the SECURE 2.0 super catch-up provision. Combined with the $24,500 standard limit, this allows total 401(k) contributions of $35,750 per year. Not all plans have adopted this provision, so check with your plan administrator. The super catch-up contributions for high earners also must be Roth.
