Social Security tax takes 6.2% of your gross wages out of each paycheck. That rate applies to every dollar you earn up to the annual wage base, which is $184,500 for 2026. So the most any employee will have withheld for Social Security this year is $11,439. Your employer pays another 6.2% on the same wages, but only your half shows up as a deduction. That is how much Social Security is taken out of a paycheck for a W-2 employee, and the figure holds whether the pay is salary, hourly, overtime, bonus, or commission.1Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax
How the 6.2% Is Calculated
The rate is flat. It does not change with filing status, pay frequency, or income level. Earn $1,000 in a pay period and $62 goes to Social Security. Earn $5,000 and it’s $310.1Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax
Social Security is only part of what most people call FICA. The other part is Medicare, withheld separately at 1.45% with no wage cap. Together they total 7.65% of gross wages, and that combined figure is what many pay stubs label “FICA.”2Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates If your stub shows a single FICA line larger than 6.2% of your pay, it is almost certainly combining the two.
When Withholding Stops for the Year
Once your year-to-date wages cross $184,500, Social Security withholding stops for the rest of the calendar year.3Social Security Administration. Contribution and Benefit Base If you earn $220,000 in 2026, you pay the 6.2% on the first $184,500 and nothing on the remaining $35,500. Medicare keeps coming out, since it has no cap.4Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security?
High earners often notice a bigger paycheck late in the year for that reason. Payroll software tracks the running total automatically. In January the counter resets and withholding starts again from dollar one.
What Counts as Social Security Wages
Only earned income is subject to the 6.2%. Wages, salaries, bonuses, commissions, and tips all count. Interest, dividends, capital gains, rental income, pensions, and annuity payments do not.5Social Security Administration. What Income Is Included in Your Social Security Record?
A common surprise involves 401(k) contributions. Money you put into a traditional 401(k) is deferred from federal income tax, but Social Security and Medicare tax still apply.6Internal Revenue Service.

Payroll deductions for health insurance premiums, flexible spending accounts, and health savings accounts made through a Section 125 plan are generally exempt from Social Security and Medicare tax.7Internal Revenue Service. FAQs for Government Entities Regarding Cafeteria Plans Those deductions lower your Social Security wages now, which trims your tax but can also slightly reduce your future benefit, since benefits are calculated from your taxable earnings history.

If You Are Self-Employed
When you work for yourself, there is no employer to split the bill. You owe the full 12.4% Social Security portion on your net self-employment income, plus 2.9% for Medicare, for a combined self-employment tax rate of 15.3%.11Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax The same $184,500 wage base caps the Social Security piece.

Checking the Withholding on Your Pay Stub
Social Security withholding is usually labeled “OASDI” or “FICA-SS,” with an amount for the pay period and a running year-to-date total. A stub that shows only “FICA” is likely combining Social Security and Medicare.
The definitive record is your W-2. Box 3 is your Social Security wages; Box 4 is the Social Security tax withheld. Box 4 divided by Box 3 should equal 0.062. If it doesn’t, either your wages crossed the $184,500 cap partway through the year, which is normal, or the employer made an error. For 2026, Box 4 should not exceed $11,439.18Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026) Self-employed workers won’t get a W-2; the calculation happens on Schedule SE when you file, and the Social Security Administration uses those figures to build your earnings record the same way it does for employees.
