Social Security

Social Security is the largest federal program, paying benefits to retired workers and their dependents and survivors through the Old-Age and Survivors Insurance program and to disabled workers and their dependents through the Disability Insurance program. Those benefits are financed primarily by payroll taxes. CBO projects Social Security’s finances under current law and analyzes a wide variety of possible changes to the law. (A separate page on Disability Insurance provides additional information about CBO’s work on that part of Social Security.)
