Social Security takes 6.2% out of your paycheck. Your employer pays a matching 6.2% on top of your wages, so the total going into the system on your behalf is 12.4%. In 2026, the tax only applies to the first $184,500 you earn in the year; anything above that is not subject to Social Security withholding.1Social Security Administration. Contribution and Benefit Base If you earn $1,000 in a pay period, $62 comes out for Social Security.
What the 6.2% Applies To
Federal law sets the employee rate at 6.2% of wages.2Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax Your employer withholds it from your gross pay, meaning the total before deductions for health insurance, retirement contributions, or anything else. It applies to base pay, bonuses, and commissions alike.
Social Security is only part of what you’ll see labeled FICA on your pay stub. Medicare adds another 1.45%, bringing the combined employee rate to 7.65%.3Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet The two taxes behave differently past a certain income level: Social Security stops at the annual wage cap, while Medicare has no cap and actually adds a 0.9% surcharge on wages above $200,000 for single filers or $250,000 for joint filers.4Internal Revenue Service. Topic No. 560, Additional Medicare Tax
The $184,500 Wage Cap
Once your year-to-date wages hit $184,500 in 2026, the 6.2% withholding stops for the rest of the calendar year. Someone earning $220,000 pays Social Security tax only on the first $184,500, for a maximum contribution of $11,439.1Social Security Administration. Contribution and Benefit Base Your employer’s matching 6.2% stops at the same point. The cap adjusts each year based on national average wage changes.
Payroll systems track year-to-date earnings automatically, so a single employer will stop withholding at the right moment. Multiple employers in the same year are a different story, covered below.
What Self-Employed Workers Pay
If you work for yourself as an independent contractor, freelancer, or small business owner, you pay both halves: a combined 12.4% Social Security rate.5Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax You owe the tax once your net self-employment earnings reach $400 for the year.6Internal Revenue Service. Topic No. 554, Self-Employment Tax
The 12.4% does not apply to your full net profit. You first multiply your net self-employment income by 92.35% to get the taxable amount. This adjustment mirrors the tax break employees get because their employer’s share isn’t treated as their income.6Internal Revenue Service. Topic No. 554, Self-Employment Tax A freelancer with $50,000 in net profit would calculate the Social Security portion as $50,000 × 0.9235 × 12.4%, or roughly $5,726, not $6,200.
Payments are typically made through quarterly estimated taxes on Form 1040-ES, due in April, June, September, and the following January.7Internal Revenue Service. Form 1040-ES – 2026 – Estimated Tax for Individuals You can then deduct the employer-equivalent portion (half of your self-employment tax) when calculating your adjusted gross income.8Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The deduction lowers your income tax but does not reduce the self-employment tax itself. The $184,500 cap still applies, so the 12.4% rate stops applying to earnings above that (after the 92.35% adjustment).
When You Might Not Owe It
Almost every worker pays Social Security tax on every paycheck. Two narrow exceptions exist.
Students Working for Their School
If you’re enrolled at least half-time at a college or university and you work for that same school, your wages may be exempt from Social Security and Medicare tax. The work has to be tied to your course of study rather than a career position at the institution.9Internal Revenue Service. Student FICA Exception Professional employees don’t qualify, even if they’re also enrolled as students.
Members of Certain Religious Groups
Members of recognized religious groups conscientiously opposed to insurance benefits, including some Amish and Mennonite communities, can apply for an exemption.10Social Security Administration. Are Members of Religious Groups Exempt From Paying Social Security Taxes? The group must have continuously provided its own food, shelter, and medical care for members since at least December 31, 1950, and the individual must waive all rights to Social Security benefits. Applicants file Form 4029 with the IRS.
What If Too Much Was Withheld
If you worked more than one job in the same year, each employer withheld Social Security tax on its own without knowing what any other employer had already taken out. Your combined withholding can end up above the annual maximum.11Social Security Administration. Maximum Taxable Earnings You claim the excess as a credit on your federal income tax return, which either reduces the tax you owe or increases your refund.12Internal Revenue Service. Topic No. 608, Excess Social Security and RRTA Tax Withheld The Instructions for Form 1040 spell out where to report it.
