1. The SECURE 2.0 Roth Catch-Up Contribution Rule Arrives in 2026

Many Americans are working longer than ever. According to Pew Research, roughly 20% of Americans age 65 and older are still in the workforce. If you fall into that group — or plan to — the new Roth catch-up rule under SECURE 2.0 could significantly change how your retirement contributions are taxed.

What changed?

Historically, workers age 50 and older could make catch-up contributions to employer-sponsored retirement plans like a 401(k), 403(b), or government 457(b). These catch-up contributions could typically be made on a pre-tax basis, reducing your taxable income.

Starting in 2026, however, high-earning workers will be required to make catch-up contributions as Roth contributions, meaning they are made with after-tax dollars.

This provision — often referred to as the “Roth mandate” — was delayed once already, but employers must begin complying January 1, 2026, even though full implementation doesn’t conclude until 2027.

Who is affected?

The Roth catch-up rule applies to:

• Workers (including working retirees) age 50 or older
• Participants in a 401(k), 403(b), or governmental 457(b) plan
• Individuals who earned $150,000 or more from their current employer in the prior year (indexed for inflation)

If you meet these criteria, your catch-up contributions can no longer reduce your taxable income.

Why this creates a tax trap

For many retirees and pre-retirees, losing a pre-tax deduction can create a chain reaction of higher taxes, including:

• Higher adjusted gross income (AGI)
• Increased taxation of Social Security benefits
• Potential Medicare IRMAA premium surcharges
• Phase-outs of other retirement-related tax deductions
