How To Calculate FICA Tax

The FICA tax (Federal Insurance Contribution Act) tax is an employee payroll tax that funds Social Security benefits and Medicare health insurance. The tax is split between employers and employees. They both pay 7.65% (6.2% for Social Security and 1.45% for Medicare) of their income to FICA, the combined contribution totaling 15.3%. The maximum taxable earnings for employees as of 2020 is $137,700. There is no wage limit for Medicare.

FICA Tax Calculation

To calculate FICA tax contribution for an employee, multiply their gross pay by the Social Security and Medicare tax rates. For example, if an employee’s taxable wages are $700 for the week, their social security contribution would be: $700.00 x 6.2% = $43.40. Their Medicare contribution would be: $700.00 x 1.45%= $10.15. These are also the amounts the employer would pay.
