Federal Insurance Contributions Act (FICA)
A reference used to indicate the combination of the Social Security tax and the Medicare tax. 
For the year 2016, the employee's portion of the FICA tax is 7.65% (the Social Security tax of 6.2% plus the Medicare tax of 1.45%) on the first $118,500 of an employee's salary and wages. 
On an employee's salary and/or wages in excess of $118,500 the employee's portion of the FICA tax is 1.45% (consisting of only the Medicare tax). In addition, certain employees will be subject to a 0.9% Medicare surtax. The surtax will apply to wages, salaries, and a self-employed person's net income that are in excess of specified amounts. See IRS.gov for details on the Medicare surtax.
