The Federal Insurance Contributions Act (FICA) is a United States federal law that requires employers and employees to pay a certain percentage of their income into a trust fund that provides Social Security benefits and Medicare benefits.
FICA is important because it helps to ensure that all Americans have access to these vital programs. The benefits provided by Social Security and Medicare are essential for many Americans, and FICA helps to guarantee that these programs will be there for future generations. FICA has been in place since 1935, and it has played a major role in the development of the American social safety net.
