The hook
“If someone is still planning 2026 retirement contributions off last year's limits, the spreadsheet is already behind.”
The IRS announced a 2026 401(k) limit of $24,500 and an IRA limit of $7,500, with separate catch-up figures continuing to matter for older taxpayers. The COLA guidance matters because these are planning numbers, not trivia. Salary deferral decisions and owner-compensation models often get adjusted around them.
The takeaway
Retirement tax planning ages badly when the limits move and the model does not.
