Which federal agency is responsible for administering social insurance programs?

The Social Security Administration (SSA) is the federal agency tasked with administering social insurance programs, most notably Social Security and Supplemental Security Income (SSI). This includes not only managing the distribution of benefits to retirees but also overseeing disability and survivor benefits for those who qualify. The agency plays a crucial role in providing financial support to millions of Americans, which is essential for their well-being, particularly during retirement or in times of disability.

The other options represent different agencies with distinct responsibilities. The Federal Insurance Corporation does not exist as a recognized federal agency, while the Department of Health and Human Services focuses on national health policies and public health programs, and the Internal Revenue Service is primarily responsible for tax collection and enforcement of tax laws. Each of these agencies contributes to different aspects of federal services, but only the Social Security Administration specifically handles social insurance programs.
