The act authorized Congress to appropriate funds to the reserve account and separately established a new payroll tax sufficient to provide those funds. The Social Security trust funds date back to the “Old-Age Reserve Account,” established under the 1935 Social Security Act. This article examines the cash flows and reserves from the perspective of not just the trust fund itself but also from that of the rest of the budget. In recent years, attention has focused on the cash flows' effects on the rest of the federal budget.
