How often do fica taxes change?

FICA taxes, which fund Social Security and Medicare, can change but are not adjusted on a regular basis. The Social Security tax rate has remained consistent at 6.2% for employees and 6.2% for employers, while the Medicare tax rate is 1.45% for both. Adjustments to the wage base limit for Social Security are made annually based on changes in national average wage levels. Therefore, while the rates themselves are stable, the wage base limit may change each year.
