Social Security wage base: the month your paycheck jumps
How the OASDI taxable maximum resets each January, why Social Security withholding disappears mid-year for high earners, and how Medicare differs.
OASDI taxable maximum (illustrative recent years)
Verify current-year base and rates on SSA.gov. Max employee OASDI = base × 6.2% for covered wages up to the base.
| Year | OASDI wage base | Max employee OASDI @ 6.2% |
|---|---|---|
| 2024 | $168,600 | $10,453 |
| 2025 | $176,100 | $10,918 |
| 2026 | $184,500 | $11,439 |
Why January feels heavier
Early in the year, each paycheck typically includes OASDI on covered wages until your year-to-date earnings cross the annual wage base. After that, OASDI stops for that employer for the rest of the year—so net pay can jump even if gross is flat.
This is not a secret “raise”—it is the natural shape of a capped payroll tax.
Medicare does not mirror Social Security
Medicare Hospital Insurance generally continues without an OASDI-style wage ceiling. High earners may also see Additional Medicare Tax above threshold amounts.
That is why “Social Security is done” does not mean “all payroll taxes are done.”
Multiple jobs and over-withholding
If you work two covered jobs and combined wages exceed the base, you may have too much OASDI withheld in total. Your Form 1040 can credit excess OASDI withheld when applicable—follow IRS instructions.

Use the jump in net pay for savings or debt goals—don’t inflate lifestyle on a timing effect.
