One of the most consequential provisions of the SECURE 2.0 Act took effect on January 1, 2026, and it changes the math for millions of workers approaching retirement. If your FICA wages from your employer exceeded $150,000 in 2025, you can no longer make pre-tax catch-up contributions to your 401(k), 403(b), or governmental 457 plan. Those dollars must now be designated as Roth contributions — funded with after-tax money.
For many high earners who built their retirement strategy around maximizing pre-tax deferrals in their peak earning years, this is a meaningful shift.
What the New Rule Says
The 2026 elective deferral limit climbed to $24,500, up $1,000 from 2025. Workers age 50 and older can add a standard catch-up contribution of $8,000, while those aged 60 through 63 qualify for a higher "super catch-up" of $11,250. In total, a 60-year-old can defer up to $35,750 in a single year.
But here is the catch: if the prior-year W-2 wages from the employer sponsoring the plan exceeded $150,000, the catch-up portion — and only the catch-up portion — must be routed to a designated Roth account. The base $24,500 deferral can still go in pre-tax. The threshold will be indexed for inflation annually.
Why It Matters for Retirement Strategy
The shift removes a planning tool many high earners have relied on: deferring income in peak years and pulling it out in retirement at presumably lower tax rates. Under the new rule, catch-up dollars come out of net pay, not gross pay. A worker in the 32% federal bracket making a full $8,000 catch-up contribution effectively loses roughly $2,560 in current-year tax savings compared to the pre-tax treatment available in 2025.
The flip side is real, however. Roth contributions grow tax-free, are never subject to required minimum distributions during the original owner's lifetime, and do not inflate the modified adjusted gross income figure that triggers Medicare Part B and Part D surcharges in retirement — surcharges that kick in at $109,000 for single filers and $218,000 for joint filers.
Who Is Exempt
Not every high earner is captured. The rule is keyed to FICA wages reported on a W-2 from the plan-sponsoring employer. Sole proprietors and partners receiving K-1 distributive shares from a partnership do not receive FICA wages on that income. A solo 401(k) participant who is self-employed can continue making pre-tax catch-up contributions regardless of income.
Workers who switched employers mid-year may also fall below the threshold at their new employer if their wages from that specific employer did not cross $150,000 in the prior year.
Practical Steps Before Year-End
Confirm your plan offers a Roth option. Plans without a Roth 401(k) feature cannot accept catch-up contributions from affected workers at all under the final regulations. If yours hasn't been updated, your catch-up may be blocked entirely until it is.
Rerun your retirement tax projections. A multi-year Roth conversion plan looks different when $8,000 to $11,250 of after-tax money is already flowing in annually.
Coordinate with IRA strategy. The 2026 IRA contribution limit is $7,500 with a $1,100 catch-up. Households at higher incomes may want to revisit whether traditional or Roth IRA contributions still make sense alongside the new forced Roth catch-up.
Watch the wage threshold each year. Because the $150,000 figure is now indexed, some workers will move in and out of the rule's reach as inflation adjustments apply.
The mandatory Roth catch-up is one of the clearest examples of Congress nudging retirement savers toward tax diversification. For workers in their 50s and early 60s, the right response is rarely to contribute less — it is to model the long-term math more carefully and use the forced Roth bucket as part of a deliberate tax strategy in retirement.
