The Social Security Administration will tax wages up to $192,300 in 2027, up from $184,500 this year. The new taxable maximum, announced alongside the 3.6% cost-of-living adjustment on Oct. 14, 2026, takes effect on Jan. 1, 2027 and mainly affects workers earning more than about $184,500 a year.
What the taxable maximum is
Social Security is funded by a 12.4% payroll tax, split evenly between employee and employer at 6.2% each. That tax only applies to earnings up to a yearly cap, called the taxable maximum or wage base. Earnings above the cap are not taxed for Social Security and do not count toward future benefits.
The cap rises most years in line with the national average wage index. For 2027 it climbs by $7,800, a 4.2% increase, which is larger than the 3.6% COLA because wages grew faster than consumer prices over the measurement period.
How much more high earners will pay
| Year | Taxable maximum | Max employee Social Security tax (6.2%) | Max self-employed tax (12.4%) |
|---|---|---|---|
| 2026 | $184,500 | $11,439.00 | $22,878.00 |
| 2027 | $192,300 | $11,922.60 | $23,845.20 |
An employee earning $192,300 or more will pay up to $483.60 more in Social Security tax in 2027 than in 2026, and the employer matches that amount. Self-employed workers, who pay both halves, will owe up to $967.20 more, although half of the self-employment tax remains deductible on their federal return.
If you earn less than $184,500, the change does not touch your paycheck. Your Social Security tax stays at 6.2% of everything you earn.
Medicare tax has no cap
The 1.45% Medicare portion of the payroll tax applies to all wages with no upper limit. Workers also pay an additional 0.9% Medicare tax on wages above $200,000 for single filers and $250,000 for married couples filing jointly. Those thresholds are set in law and are not indexed, so they do not change for 2027.
Other 2027 Social Security numbers that changed
- COLA: Benefits rise 3.6% starting with January 2027 payments. SSI recipients see the increase on Dec. 31, 2026.
- Earnings test, under full retirement age: $25,560 a year (up from $24,480). Above that, $1 in benefits is withheld for every $2 earned.
- Earnings test, year you reach full retirement age: $67,920 (up from $65,160), with $1 withheld for every $3 earned over the limit until the month you reach full retirement age.
- Work credit: One credit now requires $1,970 in earnings (up from $1,890). You still need 40 credits to qualify for retirement benefits.
What it means for you
For most workers, the only visible change in January is the 3.6% COLA if you already receive benefits, or nothing at all if you are still working and earn under the cap. High earners should expect the Social Security line on their pay stub to keep appearing a little longer into the year before it stops, because it now takes until $192,300 of wages to hit the ceiling.
If you are self-employed and make estimated tax payments, update your 2027 calculations now so the higher cap does not produce a surprise in April 2028.
