How undocumented immigrants add billions to Social Security despite strict limits on collecting benefits later

Payroll taxes reach Social Security

Millions of undocumented immigrants work in the United States and have Social Security taxes withheld from paychecks, even though strict benefit rules often limit their access to payments later.

Those payments enter a retirement system facing long-term financing pressure, linking this workforce to payroll records, benefit rules, and immigration policy across federal programs that shape later claims.

Social Security began as insurance

President Franklin D. Roosevelt signed the Social Security Act in 1935, creating worker-funded insurance linked to covered wages and retirement income for older Americans after regular work ended.

The program relies mainly on payroll taxes from employees, employers, and self-employed workers, with revenue moving into trust funds that pay eligible beneficiaries each month across the country.

Payroll withholding comes first

Employers withhold Federal Insurance Contributions Act taxes from covered wages, including 6.2% for Social Security from workers and another 6.2% from employers, under payroll rules.

That withholding can occur when a worker lacks lawful employment status, because payroll systems process the number listed on employment and tax forms during each regular pay period.

Tax numbers have narrow limits

The Internal Revenue Service issues Individual Taxpayer Identification Numbers (ITINs) for federal tax purposes to individuals who do not qualify for Social Security numbers under federal identification rules.

An ITIN allows tax filing and refund claims, but it does not authorize work, change immigration status, or create eligibility for Social Security benefits under federal program rules.

Hiring checks changed after 1986

The Immigration Reform and Control Act of 1986 required employers to verify identity and employment authorization for people hired in the United States through standard Form I-9 records.

Form I-9 became the standard record, yet payroll taxes can still reach Social Security when names or numbers fail agency matching checks after employers report wages for workers.

Unmatched wages enter a file

When a worker’s name and Social Security number do not match agency records, the Social Security Administration records the wages in its Earnings Suspense File rather than assigning them.

The file includes many mismatch causes, but it shows how some taxes reach the system without clear benefit credit for future retirement claims under the law for affected workers.

Fun fact: Ernest Ackerman received Social Security‘s first benefit, a one-time payment of 17 cents, in January 1937, before monthly checks began.

Annual sums have grown

A federal actuarial estimate placed Social Security payroll taxes from undocumented immigrant workers and employers at $13 billion for 2010, before subsequent calculations reached higher totals for later years.

Another estimate found undocumented immigrants paid $25.7 billion in Social Security taxes during 2022, including worker and employer shares in the full payroll contribution calculation for that year.

Little-known fact: Ida M. Fuller received the first monthly Social Security benefit, and her first check was $22.54 on January 31, 1940.

Benefit access stays limited

Undocumented immigrants generally cannot collect Social Security retirement benefits based solely on unauthorized work because federal rules require lawful presence, eligibility, and earnings records that can be verified when benefits are claimed.

Some workers may later qualify if their legal status changes, past earnings can be credited correctly, and they meet regular requirements, such as earning enough covered work credits.

Families follow separate rules

Family members do not automatically share one worker’s benefit path because eligibility can depend on legal status, relationship, age, and the worker’s earnings record under federal claims rules.

That distinction matters because a worker’s tax payments and a relative’s eligibility can follow separate legal paths within the federal benefit system, even in the same family home.

Other taxes add context

Payroll contributions make up only one part of the fiscal picture, because undocumented immigrants also pay federal income taxes through filings and withholding in many households each year.

They also contribute through Medicare payroll payments, sales taxes, property costs passed through in rent, and other local charges tied to daily life in their communities.

Trust fund pressure frames the issue

Social Security trustees projected that combined program reserves would be depleted in 2034, with incoming revenue covering 83% of scheduled benefits under intermediate assumptions released publicly in June 2026.

Undocumented workers do not close that gap, but their payroll contributions add revenue without matching payments for many people in that group under the present federal benefit eligibility rules.

Policy choices carry tradeoffs

Immigration enforcement, work authorization rules, and Social Security financing do not operate separately, because payroll revenue depends partly on who works in covered jobs across industries and regions.

Reducing undocumented employment may lower some future tax inflows, while broader legal status may change who documents earnings, earns credits, and later qualifies under revised federal eligibility rules.

The bottom line remains complicated

The system collects money from many undocumented workers before federal rules determine whether those people can use the retirement program they helped finance through ordinary payroll systems while employed.

That gap shows a fiscal pattern: people outside regular legal status add billions to Social Security while collecting little from it under current rules over many years.
