Mandatory spending

Federal spending set by permanent law rather than annual appropriations, including Social Security, Medicare and Medicaid.

Also called: direct spending, entitlement spending

Mandatory spending, also called direct spending, is money the federal government pays under standing laws rather than through yearly appropriations. The amount depends on who qualifies and how many people apply, not on a fixed budget set annually.

The largest programs are Social Security, Medicare and Medicaid, together with others such as nutrition assistance, veterans' benefits and interest on the debt (which is often treated separately because the government must pay it). Congress changes these programs by passing new law, such as an authorization bill or reconciliation, not through the appropriations process. Some programs, like Social Security, are funded by dedicated payroll taxes.

Mandatory spending makes up a majority of the federal budget, and its share has grown as the population ages and health costs rise. Fiscal conservatives argue that this growth drives the long-run debt problem and that the annual budget fight over discretionary spending misses the larger piece. Others respond that these programs provide earned benefits and that cuts would harm retirees and the poor. Many budget plans propose changing eligibility or benefit formulas. See also entitlement.
