The history of Social Security begins on August 14, 1935, when President Franklin D. Roosevelt signed the Social Security Act into law. That single statute, Public Law 74-271, replaced a patchwork of local charities and poorhouses with a federal system of old-age benefits, unemployment insurance, and welfare grants, and it set up the payroll-tax-funded retirement program Americans still pay into today.1U.S. Government Publishing Office. Social Security Act Everything since has been an amendment to that original design.
What the 1935 Act Actually Created
The Act bundled several programs together rather than launching a single benefit. Title I gave federal grants to states so they could immediately send cash to elderly people already in poverty, which was straightforward welfare for people too old to wait for a pension system to mature.2Social Security Administration. Old-Age Provisions of the Federal Social Security Act Title II created the contributory old-age insurance system, where workers paid in through payroll taxes and collected retirement benefits later. That is the program most people mean when they say “Social Security” today.
Title IV sent cash grants to states for Aid to Dependent Children, covering families where a child had lost parental support through death, desertion, or a parent’s inability to work.3U.S. Department of Health and Human Services. Aid to Families with Dependent Children (AFDC) and Temporary Assistance for Needy Families (TANF) – Overview Titles III and IX built the federal-state unemployment compensation framework that still governs jobless benefits, giving states wide latitude to design their own programs with federal tax incentives to participate.4Social Security Administration.

Two things people now think of as core Social Security were missing from the original law: survivor benefits for the families of workers who died, and disability insurance for workers who could no longer work. Both were added later.
Who Was Left Out
The new insurance system covered only about half the jobs in the American economy. Agricultural laborers and domestic servants were the two largest excluded groups, and government employees and nonprofit workers were left out as well.5Social Security Administration. The Decision to Exclude Agricultural and Domestic Workers from the 1935 Social Security Act
The exclusions fell hardest on Black Americans. At least 60 percent of the country’s Black workforce held agricultural or domestic jobs and therefore could not participate. The Social Security Administration’s own historical analysis acknowledges that both administrative difficulty (wage-tracking for farm and household work really was harder in the 1930s) and the racial politics of a Congress dominated by Southern Democrats shaped the decision.5Social Security Administration.

The First Taxes and the First Checks
Tax collection began in 1937 under what became the Federal Insurance Contributions Act. Employers and employees each paid 1 percent of wages, for a combined rate of 2 percent, and only the first $3,000 of annual earnings was taxable. The most any single worker could owe in a year was $30.6Social Security Administration. FICA and SECA Tax Rates7Social Security Administration. Contribution and Benefit Base That 1 percent rate held through 1949, and the $3,000 cap held until 1951.
Benefits did not flow immediately. Between 1937 and 1939, the only payments were small lump sums equal to 3.5 percent of a worker’s covered earnings. The average lump-sum death benefit in December 1939 came to $96.93.8Social Security Administration. Research Note 2: The History and Development of the Lump Sum Death Benefit
Monthly retirement checks began on January 31, 1940. The first one, for $22.54, went to Ida May Fuller of Ludlow, Vermont. Fuller had paid $24.75 in Social Security taxes over three years. She lived to 100 and collected far more than she paid in, which is how a social insurance pool is designed to work.9Social Security Administration.

Surviving the Supreme Court
The Act was challenged almost immediately, and two 1937 rulings decided its fate. In Steward Machine Co. v. Davis, the Court upheld the unemployment insurance provisions, holding that Congress could use its spending power for a problem “national in area and dimensions” and that offering states tax credits to participate was inducement, not coercion.10Justia Law. Steward Machine Co. v. Davis, 301 U.S. 548 (1937) In Helvering v. Davis, a 7-2 majority upheld the old-age benefits under Congress’s power to spend for the general welfare, treating old-age poverty as a national problem the states could not solve on their own.11Justia Law. Helvering v. Davis, 301 U.S. 619 (1937)
The 1939 Amendments: A Family Program
Before the first monthly check even went out, Congress rewrote the program’s character. The 1939 amendments added benefits for the spouse and minor children of a retired worker and, for the first time, ongoing survivor benefits for the families of workers who died before retirement.12Social Security Administration. Legislative History: 1939 Amendments A wife aged 65 or older received a supplement equal to 50 percent of her husband’s primary benefit; dependent children received similar supplements; widows and surviving children collected monthly checks in place of a one-time lump sum.13Social Security Administration. Legislative History: 1939 Amendments The agency’s own historians describe this as the moment Social Security shifted from a retirement program for workers into a family-based economic security program.
Postwar Expansion
The exclusions that had left half the workforce out in 1935 closed over the next three decades.
Coverage for Farm and Domestic Workers (1950)
The 1950 amendments, signed on August 28 of that year, brought roughly 10 million additional workers into the system. Regularly employed farm and domestic workers gained coverage, along with about 4.6 million self-employed people.14Social Security Administration. Coverage Under the 1950 Amendments
Disability Insurance (1956)
President Eisenhower signed the amendments that created Social Security Disability Insurance in 1956. To get the program passed, its supporters accepted compromises: initial benefits were limited to disabled workers between 50 and 65, and the definition of disability required an impairment that made any substantial gainful work “impossible” and was expected to last for life.15Social Security Administration. Disability Policy and History The age limit was later removed and the program grew considerably.
Medicare (1965)
President Lyndon Johnson signed the Social Security Amendments of 1965 on July 30, adding Title XVIII and creating Medicare. The law set up two programs for Americans 65 and older: hospital insurance funded by an additional payroll tax that started at 0.35 percent, and voluntary medical insurance funded partly by enrollee premiums and partly by the federal government.16Social Security Administration. Social Security Amendments of 1965
How Social Security Works Today
The 1 percent tax on the first $3,000 of wages has become something much larger. In 2026, employees and employers each pay 6.2 percent on earnings up to $184,500, plus 1.45 percent for Medicare on all earnings with no cap.17Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security? Self-employed workers pay both halves, a combined Social Security rate of 12.4 percent.6Social Security Administration.

To qualify for retirement benefits you need 40 work credits. In 2026, one credit is earned for every $1,890 in covered earnings, up to four credits a year, so the minimum is 10 years of work.18Social Security Administration. Social Security Credits and Benefit Eligibility For anyone born in 1960 or later, the full retirement age is 67. Claiming at 62 cuts your benefit by about 30 percent compared with waiting.19Social Security Administration. Retirement Benefits The average monthly retirement benefit as of January 2026 is $2,071.20Social Security Administration. What Is the Average Monthly Benefit for a Retired Worker?
Benefits were tax-free for nearly 50 years. Since 1984, a portion may be subject to federal income tax based on “combined income,” meaning adjusted gross income plus nontaxable interest plus half of Social Security benefits. Single filers with combined income between $25,000 and $34,000 can owe tax on up to 50 percent of their benefits; above $34,000, up to 85 percent becomes taxable. For joint filers, the thresholds are $32,000 and $44,000.21Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits Eight states also tax benefits, though several offer exemptions or deductions that reduce or eliminate the tax for lower-income retirees.
The Trust Fund Problem
The program’s finances are strained. The 2025 Trustees’ Report projects that the combined Old-Age and Survivors Insurance and Disability Insurance trust funds will run out of reserves in 2034. At that point, incoming payroll taxes would still cover about 81 percent of scheduled benefits; the remaining 19 percent would go unpaid unless Congress acts.22Social Security Administration. Social Security Board of Trustees: Projection for Combined Trust Fund Reserves The program does not disappear in 2034. Benefits would automatically drop to match available revenue. Every proposed fix combines some mix of higher taxes, a higher retirement age, benefit cuts, or a change to the wage cap, and Congress has so far not acted on any of them.
