FICA is the largest non-income tax deduction on most paychecks, yet it's also one of the most misunderstood. Employees see the combined 7.65 percent come off every check and often mistake it for income tax. Employers pay the same 7.65 percent match, so the full payroll tax burden for Social Security and Medicare sits at 15.3 percent of wages, the highest of any U.S. employment tax. For 2026, the Social Security Administration raised the wage base to $184,500, up from $176,100 in 2025, which pushes more wages into Social Security tax and increases the per-employee cap for higher earners.
The Two Components of FICA Social Security (Old-Age, Survivors, and Disability Insurance) taxes at 6.2 percent on each side, on wages up to the annual wage base. In 2026, the wage base is $184,500. Wages above that ceiling are exempt from Social Security tax for the rest of the year.
Medicare taxes at 1.45 percent on each side, with no wage cap. High earners pay an additional 0.9 percent Medicare tax on wages over $200,000 (single) or $250,000 (married filing jointly). Employers withhold the Additional Medicare Tax but do not match it.
Who Is Covered Most U.S. workers. Federal employees hired after 1983, state and local employees in certain systems, most religious employees, and some agricultural workers have specific rules. Self-employed individuals pay Self-Employment Contributions Act (SECA) tax at the combined rate of 15.3 percent, essentially both halves of FICA.
Why Did the Social Security Wage Base Go Up So Much for 2026? The SSA adjusts the wage base each year based on the national average wage index. The 2025 wage growth was strong enough to raise the 2026 base by about 4.8 percent, significantly above the typical 3 to 3.5 percent year-over-year move.
How FICA Gets Reported Withheld FICA is reported quarterly on Form 941 and annually on Form W-3. Each employee's W-2 breaks out Social Security wages, Social Security tax withheld, Medicare wages, and Medicare tax withheld in separate boxes.
Employers also pay their match through EFTPS on the same deposit schedule as federal income tax withholding. Late deposits carry the same 2 to 15 percent penalty tiers as FIT deposits.
Managing FICA Compliance Without Overpaying Track Social Security taxable wages per employee so the system stops withholding once an employee hits the annual wage base. Employees with multiple employers may pay excess Social Security tax in a year, which they reconcile on their personal return.
Watch for reporting errors at year-end, especially on bonus runs and final paychecks. Reference the SSA Contribution and Benefit Base page each December for next year's wage base and the IRS Publication 15 for deposit rules. Link FICA records to broader payroll documentation and to W-2 form year-end filings for a clean reconciliation.
