What changed

Compliance note
An employee whose 2026 Social Security wages (W-2, Box 3) from the employer sponsoring the plan were more than $155,000 must make 2027 catch-up contributions as Roth.
Who this affects
Employers that sponsor a 401(k), 403(b) or governmental 457 plan, and the employees who contribute to it through payroll.
Exceptions that matter:
- The ages 60 to 63 catch-up takes the place of the age 50 and over catch-up, and applies only if the plan offers it.
- The total with employer money does not count catch-up contributions.
- A plan can set a lower limit than the IRS maximum.
What to do
Confirm payroll has the 2027 limits before your first January pay date, and tell employees who want to contribute more to change their election.
