The history of Social Security begins in the depths of the Great Depression, when mass unemployment and old-age poverty pushed the federal government to build a national safety net for the first time. President Franklin D. Roosevelt signed the Social Security Act on August 14, 1935, creating retirement benefits, unemployment insurance, and aid for vulnerable groups, all funded by payroll taxes on workers and employers.1Social Security Administration. Compilation of the Social Security Laws What began as a modest retirement program covering about half the workforce has grown over nine decades into the country’s largest social insurance system, now reaching nearly every American through retirement income, disability protection, survivors benefits, and Medicare.
Why Roosevelt Pushed For a Federal Program
The Depression exposed how little protection older Americans had against economic collapse. Roosevelt issued Executive Order 6757 on June 29, 1934, creating the Committee on Economic Security to study social insurance models already running in Europe and figure out what could fit the American system. Secretary of Labor Frances Perkins chaired the group and served as the program’s chief architect and political driving force.2Social Security Administration. Social Security History
A technical staff of economists and actuaries worked under the committee, analyzing census data, projecting how many workers would need old-age protection, and studying European unemployment systems. By late 1934 the committee had recommended a dual approach: some programs run entirely by the federal government, others sharing responsibility with the states.3Social Security Administration. Social Security in America Those recommendations went to Congress in early 1935. After months of debate, the bill passed the House 371–33 and the Senate 77–6.
What the 1935 Act Created
The Social Security Act wasn’t a single program. It set up a layered system that mixed purely federal programs with joint federal-state initiatives, each aimed at a different form of economic vulnerability.
Old-Age Insurance and Old-Age Assistance
The most important distinction was between Old-Age Insurance under Title II and Old-Age Assistance under Title I. Old-Age Insurance was an earned benefit: workers paid in through payroll taxes and later collected monthly retirement payments. The federal government ran it directly. To qualify, a worker needed at least $2,000 in covered wages spread across at least five calendar years after 1936, and monthly benefits were capped at $85.4National Archives. Social Security Act (1935)
Old-Age Assistance was a need-based welfare program for people who were already old and poor when the law passed. The federal government matched state spending for impoverished individuals aged 65 and over, covering half of each state’s payments up to $30 per month per person. That immediate relief mattered because Old-Age Insurance wouldn’t start paying monthly checks for years.5Social Security Administration. The Social Security Act of 1935
Unemployment Insurance
Title IX used a tax-offset design to bring states into an unemployment system without ordering them to act. It imposed a federal excise tax on employers of eight or more workers, but employers could credit up to 90% of that tax if their state ran an unemployment fund meeting federal standards. Any state that refused was effectively donating money to the federal treasury while its employers got nothing back. Every state eventually created a program.5Social Security Administration. The Social Security Act of 1935
Aid to Dependent Children
Title IV created grants helping states support children in families where a parent was dead, absent, or unable to work. It was later renamed Aid to Families with Dependent Children and, in 1996, replaced by the Temporary Assistance for Needy Families program under the Personal Responsibility and Work Opportunity Reconciliation Act.6U.S. Department of Health and Human Services.

Who the Original Law Excluded
Section 210 of the 1935 Act defined “employment” to exclude agricultural labor, domestic service in private homes, casual labor, maritime workers, government employees at every level, and workers at religious, charitable, and educational nonprofits.5Social Security Administration. The Social Security Act of 1935 The exclusions were partly administrative, since collecting payroll taxes from scattered farms and individual households was genuinely hard in the 1930s, and partly political, since Southern lawmakers whose votes were needed for passage resisted covering a predominantly Black agricultural and domestic workforce. Roughly half the working population fell outside the system at launch. Congress didn’t begin correcting this until the 1950 Amendments extended coverage to regularly employed domestic and farm workers along with about 10 million self-employed people.7Social Security Administration. 1950 Social Security Amendments
The Supreme Court Cases That Settled Its Legality
Critics argued that Congress had no authority to impose payroll taxes for social insurance and that the federal-state unemployment scheme coerced states into compliance. The Supreme Court answered both objections in 1937.
In Steward Machine Co. v. Davis, the Court upheld the unemployment tax provisions of Title IX. Justice Cardozo, writing for the majority, held that unemployment was a national problem and that the tax-offset system freed states to act rather than forcing their hand. Every tax credit conditioned on behavior involves some temptation, he wrote, but temptation is not coercion.8Legal Information Institute. Steward Machine Co. v. Davis, 301 U.S. 548 (1937)
The companion case, Helvering v. Davis, upheld the old-age benefits of Title II. The Court held that Congress has broad discretion to spend money in aid of the “general welfare” and that the old-age benefit system did not violate the Tenth Amendment.9Justia Law. Helvering v. Davis, 301 U.S. 619 (1937) Together the two rulings settled the constitutional question, and no serious challenge to Social Security’s basic taxing-and-spending framework has succeeded since.
How Money and Benefits Started Flowing
Revenue collection began in January 1937 under what would become the Federal Insurance Contributions Act. Both employees and employers paid 1% each on the first $3,000 of annual wages, a combined rate of 2% on a maximum taxable earnings base that stayed unchanged until 1951.10Social Security Administration. FICA and SECA Tax Rates11Social Security Administration. Contribution and Benefit Base The government began issuing Social Security numbers so it could track each worker’s earnings, building a national account system that had to run on 1930s filing technology.
Under the original Act, monthly retirement benefits weren’t scheduled to begin until January 1942. Workers who reached 65 without enough covered wages received a one-time lump-sum refund equal to 3.5% of their total covered earnings. The first of those payments went out in January 1937, the same month tax collection started.12Social Security Administration. Social Security History FAQs
The 1939 Amendments Made It a Family Program
The original Act treated Social Security as a savings-and-refund system tied to each individual worker. The 1939 Amendments turned it into something closer to family insurance. Congress added benefits for the spouse and minor children of a retired worker, and survivors benefits paid to the family when a covered worker died before reaching retirement.13Social Security Administration. Legislative History – 1939 Amendments
Wives aged 65 or older and dependent children under 16 could receive supplementary benefits equal to half the retired worker’s primary benefit. Widows with dependent children received ongoing monthly payments regardless of the widow’s age, and widows 65 and over without children also qualified.14Social Security Administration. The Revised Benefit Schedule Under Federal Old-Age Insurance The amendments also moved the start date for monthly benefit payments from 1942 forward to January 1940. Ida May Fuller of Ludlow, Vermont, received check number 00-000-001, dated January 31, 1940, for $22.54, making her the first person to collect a recurring monthly Social Security benefit.15Social Security Administration.

Disability, Medicare, and Automatic COLAs
For its first two decades, Social Security covered only retirement and survivors. That changed in 1956, when President Eisenhower signed amendments creating Social Security Disability Insurance. The new program provided monthly benefits to disabled workers between 50 and 65 who met insured-status requirements based on their work history. Over time the age restriction was removed, and SSDI became the primary federal safety net for workers who can no longer earn a living because of a severe medical condition.16Social Security Administration.

The next major expansion came on July 30, 1965, when President Johnson signed the amendments creating Medicare and Medicaid. Medicare added two new titles to the Social Security Act: Part A for hospital insurance and Part B for outpatient medical insurance. Medicaid, a separate joint federal-state program, extended health coverage to low-income individuals regardless of age.17Centers for Medicare & Medicaid Services. History
Benefit amounts themselves stayed frozen for the first 35 years unless Congress passed a specific increase, and retirees watched inflation eat away at their checks while waiting for lawmakers to act. Congress fixed that in 1972 by authorizing automatic cost-of-living adjustments tied to the Consumer Price Index. The first automatic COLA took effect in July 1975 at 8%, and the adjustments have happened annually since.
How Social Security Is Funded Today
The payroll tax mechanism created in 1937 still drives Social Security’s funding, though the numbers have grown considerably. In 2026, both employees and employers pay 6.2% on earnings up to a taxable maximum of $184,500, for a combined Social Security tax rate of 12.4%. Self-employed people pay the full 12.4% themselves. A worker earning at or above the cap contributes $11,439, with the employer matching that amount.11Social Security Administration. Contribution and Benefit Base
Medicare is funded separately through a 1.45% payroll tax on employees and employers with no earnings cap. Workers earning more than $200,000 ($250,000 for married couples filing jointly) pay an additional 0.9% Medicare surtax on earnings above those thresholds, though employers do not match the extra amount.18Internal Revenue Service. 2026 Publication 926 Combined, the total FICA rate for most workers in 2026 is 7.65%, up from the 1% that applied when the first payroll taxes were collected nearly 90 years ago.10Social Security Administration.
