Social Security is always evolving to meet the needs of the American public. We’re optimistic about the future and the limitless possibilities for progress. Much of the progress we’ve made together, as a nation, is through the shared responsibility of paying Federal Insurance Contributions Act (FICA) tax. This federal payroll tax funds Social Security— programs that provide benefits for retirees, the disabled, and children of deceased workers. You help us keep millions of hard working Americans out of poverty.
