Social Security tax has a ceiling. In 2026 you pay 6.2% on the first $184,500 of wages and nothing on wages above that, so the most an employee can pay is $11,439. Medicare tax has no ceiling. Here is how the cap works for employees, the self-employed and people with more than one job.
What is the Social Security wage base?
It is the most earnings per year that Social Security tax applies to, also called the contribution and benefit base or the taxable maximum. The Social Security Administration sets it each year from the change in average wages.
| Year | Wage base | Max employee tax | Max self-employed tax |
|---|---|---|---|
| 2026 | $184,500 | $11,439 | $22,878 |
| 2025 | $176,100 | $10,918 | $21,836 |
How much is the maximum Social Security tax in 2026?
- Employees: 6.2% × $184,500 = $11,439. Your employer pays the same amount on top, which does not come out of your pay.
- Self-employed: 12.4% × $184,500 = $22,878, because you pay both halves. Self-employment tax applies to 92.35% of net profit, so you reach the cap at about $199,783 of profit.
- Wages and self-employment together: wages use up the cap first, and self-employment income only pays Social Security tax on the room left under $184,500.
The 1099 tax calculator applies the cap to self-employment tax, including when you also have a W-2 job.
When will my paycheck stop taking Social Security tax?
Once your wages for the year pass $184,500, your employer stops withholding Social Security tax until January, so your paychecks get bigger. For a salary paid every two weeks (26 paychecks a year):
| Salary | Cap reached in | Later paychecks | Social Security for the year |
|---|---|---|---|
| $200,000 | 24th paycheck | +$477 | $11,439 |
| $250,000 | 20th paycheck | +$596 | $11,439 |
| $300,000 | 16th paycheck | +$715 | $11,439 |
| $500,000 | 10th paycheck | +$1,192 | $11,439 |
Equal paychecks, no bonuses; pre-tax 401(k) contributions do not reduce wages for Social Security. "Later paychecks" is the extra take-home on each paycheck after the cap.
Bonuses count toward the cap too, so a large bonus can bring the date forward. The take-home pay calculator applies the wage base to your annual Social Security tax.
What if I have two jobs?
Each employer withholds Social Security tax on its own wages, up to $184,500, and does not know about your other job. If your combined wages pass the cap, you pay too much during the year and get the excess back when you file.
This only works across employers. If one employer withheld more than $11,439, the excess is not a tax credit: ask that employer to correct it (or file Form 843 if it will not). Married couples filing jointly figure any excess separately for each spouse.
Is there a cap on Medicare tax?
No. Medicare tax of 1.45% applies to every dollar of wages. On top of that, the Additional Medicare Tax of 0.9% applies to wages above $200,000 for single filers and $250,000 for married couples filing jointly. Employers start withholding it once your wages with them pass $200,000, whatever your filing status, so some couples owe more at tax time and some get part of it back.
