If you are age 50 or older and your prior wages exceeded the high-earner threshold, your retirement savings strategy may have quietly shifted — whether you realized it or not.

What Changed in 2026?

Under the SECURE 2.0 Act, beginning January 1, 2026, certain retirement plan catch-up contributions must be made as Roth (after-tax) contributions for high-income participants.

While your base contribution limit can still be pre-tax, any catch-up amount above that limit must now be Roth for high earners. This change applies to individuals age 50+ whose prior-year wages exceed the high-earner threshold. For 2026 contributions, the threshold is $150,000 in 2025 wages. (IRS Notice). Affected plans include:

• 401(k) plans
• 403(b) plans
• Governmental 457(b) plans

Prior to 2026, participants could generally choose whether catch-up contributions were Traditional (pre-tax), or Roth (after-tax). Starting in 2026, high earners lose the ability to take the pre-tax deduction on catch-up contributions.

Important Details

The mandatory Roth requirement applies if prior-year FICA wages exceed $150,000 in 2025 (indexed for inflation), based on W-2 Box 3 (Federal Register).

If your employer’s plan does not offer Roth contributions, catch-up contributions cannot be made until the plan is updated.

Why This Matters

This change is not just technical — it affects both current taxes and long-term retirement strategy.

• Loss of Immediate Tax Deduction

• Previously, pre-tax catch-up contributions reduced taxable income.
• Beginning in 2026, affected participants will pay taxes on these contributions today rather than in retirement. This may increase current-year tax liability or reduce take-home pay.

• Higher Contribution Limits with New Tax Treatment

• SECURE 2.0 also created a higher “super catch-up” limit for ages 60–63. 

• 2026 Catch-Up Limits by age: 
• Ages 50–59: $8,000
• Ages 60–63: $11,250
• Ages 64+: $8,000

• For high earners above the income threshold, the entire catch-up amount must be Roth.

• Plan Design Considerations

• Employers must offer a Roth contribution option to allow eligible employees to make catch-up contributions.
• Plans that do not implement Roth capability will effectively eliminate catch-up eligibility for affected participants.

From Tax-Deferred to Tax-Free

While the loss of a current deduction may feel negative, Roth contributions offer long-term advantages:

• Tax-free growth
• Tax-free withdrawals in retirement (if qualified)
• Greater tax diversification
• Reduced exposure to future tax rate uncertainty

For many investors, the mandatory Roth shift effectively builds a tax-free bucket in retirement — a core pillar of modern retirement income planning.

Action Items

• Check Your W-2 (Box 3)

The mandatory Roth rule applies if your 2025 Social Security (FICA) wages exceeded $150,000. Do not rely on gross pay or Box 1 taxable wages. If Box 3 is above $150,000, any catch-up contributions you make in 2026 must be Roth. This amount may change annually as it is set to be indexed for inflation. 

• Verify Your "Super Catch-Up" Eligibility

If you turn age 60, 61, 62, or 63 in 2026, you may qualify for the larger catch-up contribution. If you exceed the $150k income threshold, your employer must treat this entire amount as Roth.

• Adjust Withholding or Estimated Payments

Because catch-up contributions (up to $11,250) no longer reduce taxable income, your take-home pay may be slightly lower due to increased tax withholding.

If you typically aim for a specific refund or break-even at tax time, consider updating your Form W-4 or estimated tax payments to account for the loss of this deduction.

Bottom Line

SECURE 2.0 quietly shifts retirement savings strategy for high-income professionals nearing retirement.

The move toward mandatory Roth catch-up contributions increases the importance of proactive planning, particularly for individuals balancing:

• High income
• Equity compensation
• Business ownership income
• Multiple retirement accounts

Like many tax law changes, the impact is manageable — but best addressed intentionally rather than reactively. Navigating these new catch-up rules can be tricky.
