Episode notes
401k Overcontribution Causes Double Taxation
- Workplace plan over-contributions result in double taxation if not corrected by April 15 of the following year.
- You pay income tax on the excess in the contribution year and again when you withdraw it in retirement, plus you must remove any earnings.
Fix 401k Excesses By April 15
- Correct workplace plan excesses by April 15 to avoid penalties and the 10% early withdrawal charge on earnings.
- Contact your plan administrator to withdraw excess contributions plus earnings (or report losses) before the tax-filing deadline.
Know 2026 401k Limits And Employer Exception
- Check 2026 workplace contribution limits: $24,500 under 50, $32,500 for 50+, and $35,750 for ages 60–63.
- Employer contributions don’t count toward your elective deferral limit, so only your paycheck contributions can cause excesses.
