Formula
Social Security = 6.2% of wages up to the $176,100 wage base (2025). Medicare = 1.45% of all wages. Additional Medicare = 0.9% on wages above $200,000 (single) or $250,000 (married).
How it works
Social Security stops once you hit the annual wage base, so very high earners pay it on only the first $176,100. Medicare has no cap, and an extra 0.9% kicks in above the threshold. Employers match the 6.2% and 1.45%, but not the additional 0.9%.
Frequently asked questions
What is FICA?⌄
FICA is the federal payroll tax that funds Social Security and Medicare. For most employees it is 7.65% of wages (6.2% + 1.45%), withheld automatically, with the employer paying a matching share.
Why does Social Security tax stop at a certain income?⌄
Social Security tax applies only up to an annual wage base — $176,100 in 2025. Wages above that are not subject to the 6.2% Social Security portion, though Medicare still applies.
Who pays the Additional Medicare tax?⌄
Employees pay an extra 0.9% Medicare tax on wages above $200,000 (single) or $250,000 (married filing jointly). Employers do not match this portion.
