Is Roth Right for You?

The decision whether Roth accounts suit an individual's retirement strategy has renewed attention in early 2026 after landmark tax legislation removed a major source of prior urgency.

In July 2025, Congress passed the One Big Beautiful Bill Act (OBBBA), which made permanent the lower individual income tax rates and brackets enacted under the 2017 Tax Cuts and Jobs Act. Those provisions had been set to expire after December 31, 2025, which would have raised top rates back toward 39.6% and narrowed brackets beginning in 2026. The permanence eliminates the once-pressing deadline to convert traditional IRA or 401(k) assets to Roth before higher rates took effect.

Even without an impending rate hike, the question persists for many households. Converting shifts assets to a vehicle offering tax-free qualified withdrawals and no lifetime required minimum distributions (RMDs) for the owner. This can reduce future taxable income that might otherwise push retirees into higher brackets, increase Social Security benefit taxation, or trigger higher Medicare Part B and D premiums via IRMAA surcharges.

The change also supports tax diversification: blending pre-tax, Roth, and taxable accounts allows more control over withdrawal sequencing to manage lifetime tax liability. For heirs, Roth assets remain more advantageous under post-SECURE Act rules that generally require non-spouse beneficiaries to deplete inherited IRAs within ten years.

In 2026, new rules add layers. Catch-up contributions (extra amounts for those 50+) in employer plans like 401(k)s or the federal TSP now must be Roth-only for high earners—those with prior-year compensation exceeding $145,000—rather than pre-tax. Direct Roth IRA contributions see inflation-adjusted limits of $7,500 ($8,600 catch-up), with phaseouts beginning at $153,000 modified adjusted gross income (MAGI) for singles and $242,000 for joint filers.

Market dynamics matter too. Converting during periods of lower asset values means paying taxes on a smaller base, with subsequent growth occurring tax-free. While the legislative shift eased one driver, evolving personal finances, longevity risk, and policy stability keep the Roth question relevant for anyone with meaningful pre-tax retirement savings.
