The IRS has now issued Notice 2025-67, setting forth section 415 and several other IRS limits for 2026. Maximum employee deferrals under a 401(k) plan went up from $23,500 to $24,500. Catch-ups for those over 50 went up from $7,500 to $8,000, while catch-ups for those ages 60-63 stayed the same at $11,250. However (new for this year), catch-ups for those with previous year’s Social Security wages of at least $150,000 must be made as Roth contributions.
The Social Security Administration had already issued a news release indicating that the Social Security wage base will rise from $176,100 to $184,500 for 2026.
