What are the Trust Funds?

The Social Security trust funds are financial accounts in the U.S. Treasury. There are two separate Social Security trust funds, the Old-Age and Survivors Insurance (OASI) Trust Fund pays retirement and survivors benefits, and the Disability Insurance (DI) Trust Fund pays disability benefits.

Social Security taxes and other income are deposited in these accounts, and Social Security benefits are paid from them. The only purposes for which these trust funds can be used are to pay benefits and program administrative costs.
