Contributed Too Much to Your 401(k)? How to Fix a 402(g) Excess Deferral Before April 15
For 2026 the section 402(g) elective deferral limit is $24,500 per person ($32,500 with the age-50 catch-up, $35,750 at ages 60 to 63), aggregated across every 401(k), 403(b), SIMPLE IRA and SARSEP you contribute to in the year. An excess not refunded with earnings by April 15 is taxed twice, once as wages in the contribution year and again on distribution. Steps include totaling W-2 Box 12 deferrals, notifying the plan in writing, reading 1099-R codes P and 8, and capping payroll after a mid-year job change.
