What are FICA Taxes?

FICA taxes are payroll taxes withheld from employee paychecks and paid by employees and employers for (1) Social Security (OASDI) and (2) Medicare.  This article gives you information about how to calculate FICA taxes, how to report and pay these taxes, what earnings are not part of FICA taxes, and more.

FICA taxes are the Social Security and Medicare taxes paid by individuals and employers.

The total FICA tax is 15.3%. That percentage is applied to the employee's gross pay.

Here is the breakdown of these taxes:

  • The employer and employee each pays 7.65%.
    Breaking these percentages down further:
  • The OASDI (Social Security) portion is 6.2%, up to the annual maximum wages subject to Social Security.
  • The Medicare portion is 1.45% for each employee, on all employee earnings.

The Social Security portion is capped each year at a set amount; the Medicare portion is not capped.

What Wages are Not Subject to FICA Taxes? 

Some pay items and payments to certain individuals are not subject to FICA taxes. Read this article for a definition of "social security wages" and a list of pay items that are exempt from Social Security tax. 

How are FICA Taxes Calculated? 

To calculate the FICA withholding for employees, you must take the employee's gross pay  (including overtime) and multiply by the employee rate of 7.65%.

 Two important points you must watch in your calculations: 

  • You must watch to see that the employee's total gross pay for the year does not exceed the Social Security maximum for the current year because you can't deduct more than the maximum Social Security amount each year. 
  • You must also watch to see that the additional Medicare tax is withheld on the earnings of higher paid employees, when their earnings reach $250,000 in a year. 

    Note that there is no maximum Social Security tax for employers and there is no maximum Medicare tax for employers or employees. 

    See this article for details on how to calculate FICA withholding and payments of FICA taxes to the IRS. 

    If You Withhold Too Much FICA Tax

    Did you deduct too much Social Security tax from an employee? Maybe it was because you kept on deducting above the Social Security maximum.  In any case, you must refund the money to the employee.

    Paying FICA Taxes to the IRS

    You must send FICA tax deposits, along with amounts withheld from employee pay for federal income tax, to the IRS periodically.  The deposits must be made using the Electronic Federal Tax Payment System (EFTPS) and they are made either semi-weekly or monthly, depending on the average size of deposits for the past year (new businesses deposit monthly).  Read more about how to determine when to make payments for FICA and federal income taxes.

    Reporting FICA Taxes to the IRS

    Employers must send a quarter payroll tax report to the IRS on Form 941.

    This report, due on the last day of the month after the end of each quarter, shows amounts deducted from employee paychecks, amounts due from employers, and amounts paid during the quarter.
