2027 Social Security Wage Base: How It Changes Your Paycheck
On October 14, 2026, the Social Security Administration announced its 2027 numbers. The one that matters for paychecks is the wage base, the maximum amount of earnings subject to Social Security tax. It rises from $184,500 in 2026 to $192,300 in 2027.
If you earn less than $184,500, nothing changes for you. If you earn more, you will pay a little more Social Security tax next year. Here is the math.
The key numbers
| 2026 | 2027 | |
|---|---|---|
| Social Security wage base | $184,500 | $192,300 |
| Social Security tax rate (employee) | 6.2% | 6.2% |
| Maximum employee Social Security tax | $11,439 | $11,922.60 |
| Medicare tax rate | 1.45% | 1.45% |
| Additional Medicare tax | 0.9% above $200,000 (single) | 0.9% above $200,000 (single) |
The maximum employee tax goes up by $483.60 a year. Your employer pays a matching amount.
Who is affected
Only earnings between the old and new cap are newly taxed. That means:
- Under $184,500: no change in Social Security tax. 6.2% of your pay is still 6.2% of your pay.
- Between $184,500 and $192,300: you pay 6.2% on the portion above the old cap.
- $192,300 or more: you pay the full $483.60 increase.
Examples, assuming the same salary in both years:
| Salary | 2026 Social Security tax | 2027 Social Security tax | Difference |
|---|---|---|---|
| $150,000 | $9,300 | $9,300 | $0 |
| $190,000 | $11,439 | $11,780 | +$341 |
| $200,000 | $11,439 | $11,922.60 | +$483.60 |
When the tax stops coming out of your paycheck
Social Security tax is withheld on each paycheck until your year-to-date earnings reach the cap. After that, your paychecks get larger because that deduction disappears.
Take a $200,000 salary paid biweekly (26 paychecks of about $7,692):
- In 2026: the cap is reached during paycheck 24, so the last two paychecks of the year have no Social Security tax.
- In 2027: the cap is reached during paycheck 25, so only the final paycheck is free of it.
Higher earners still get that year-end bump, but it comes later and covers fewer paychecks.
What does not change
- Medicare stays at 1.45% on all wages with no cap.
- The 0.9% Additional Medicare Tax still applies to earnings above $200,000 for single filers.
- Federal income tax is separate. The IRS usually publishes next year's brackets and standard deduction in late October or November, so we will update our guides when they are official.
If you are self-employed
You pay both halves, so the increase is double. The maximum Social Security portion of self-employment tax rises by about $967 (12.4% of the $7,800 increase). See our guide to self-employment tax.
The cost-of-living adjustment is separate
The same announcement set a 3.6% cost-of-living increase for Social Security benefits in 2027. That raises benefit payments, not paychecks, and it has no effect on what workers pay in payroll tax.
