2026 Roth catch-up contributions: check payroll wages before using the IRA rules

An existing 2026 requirement, not a new announcement today

The IRS explains that, beginning in 2026, participants in covered plans with Roth features must make catch-up contributions on a Roth basis when their prior-year wages with the plan sponsor exceeded $150,000 for this 2026 test. The exact plan and compensation rules matter. This explanation was prepared October 21, 2026 to help readers inspect payroll elections; it does not report a newly enacted rule on that date.

Keep two Roth questions separate

A personal Roth IRA contribution uses an IRA eligibility calculation, including modified adjusted gross income and filing status. An employer-plan Roth catch-up rule looks at wages with the employer sponsoring the plan. A worker can be affected by one rule without reaching the same result under the other. Household income, investment income, and wages from a particular employer are not interchangeable figures.

Locate the catch-up portion

For 2026, the general employee deferral limit for a 401(k) is $24,500, while the general age-50 catch-up is $8,000 when permitted. An eligible 55-year-old deferring $30,000 might therefore have $5,500 above the general deferral ceiling. Whether that amount is treated as catch-up depends on applicable plan limits and rules. Do not apply a personal IRA cap to that payroll election.

Ages 60 through 63 need an additional check

Certain workers who turn 60, 61, 62 or 63 during 2026 can use an $11,250 catch-up instead of the general $8,000 amount. These amounts are alternatives, not amounts to stack together. A plan’s implementation and participant eligibility still need checking. Separately, the ordinary IRA age-50 catch-up for 2026 is $1,100; that number does not describe a workplace-plan catch-up.

Questions for payroll or the plan administrator

Ask which prior-year wages were used, whether the Roth catch-up requirement applies to your participation, how payroll distinguishes regular deferrals from catch-up contributions, and how an incorrect election would be corrected. Save the answer and year-end payroll records. If you changed employers, had unusual compensation, or participate in several arrangements, obtain an explanation for those actual facts rather than assuming a salary total settles the test.

Effective dates and applicability dates can differ

The final regulations include detailed effective and applicability provisions. An implementation date for regulations is not automatically a postponement of a statutory requirement. Read the applicable IRS explanation and ask the plan administrator which provisions govern the plan’s current operation. This article supplies a checklist, not a determination of any particular plan’s compliance.
