Key Takeaways
• Undocumented immigrants paid $25.7 billion into Social Security via payroll taxes in 2022.
• They are largely ineligible to receive Social Security benefits under current U.S. law.
• Their contributions create a strong positive surplus for the Social Security trust funds.
Undocumented immigrants play a large role in the Social Security system in the United States 🇺🇸. Many people may not realize this because of the way immigration laws work and because these immigrants do not have the same access to public benefits as citizens or people with legal status. In recent years, their payments through payroll taxes have become a growing part of how Social Security trust funds stay financially healthy. At the same time, those making these payments hardly ever get money back in the form of Social Security benefits. This situation creates a positive balance for the system.
This analysis will explain how undocumented immigrants contribute to Social Security, why they cannot collect benefits, the size of their contributions, and what all of this means for the Social Security program and for broader discussions about taxes, work, and immigration in the United States 🇺🇸.

Key Findings at a Glance
- Undocumented immigrants paid about $25.7 billion into Social Security through payroll taxes in 2022 alone.
- Current U.S. 🇺🇸 law means that undocumented immigrants generally cannot draw Social Security benefits unless they later get legal status—a rare event.
- As a result, the balance between what undocumented immigrants pay in and what they receive is strongly positive for the Social Security trust funds.
- About one-third of all tax payments made by undocumented immigrants go to social insurance programs such as Social Security, even though they cannot access these programs.
- Their contributions help keep the Social Security system stronger for all Americans, at least under the current law.
Understanding Social Security Contributions by Undocumented Immigrants
Every worker in the United States 🇺🇸 who receives a paycheck generally sees part of their wages taken out for Social Security payroll taxes. For American citizens and many legal immigrants, these payments build up a work record that can later make them eligible for monthly benefits when they retire, become disabled, or after they die (for their families).
However, millions of undocumented immigrants also work for employers who withhold Social Security payroll taxes from their wages. These workers may use borrowed, made-up, or false Social Security numbers. Although the numbers are not valid for legal work, employers often use them so they can process the payroll, pay taxes, and follow business regulations. The Social Security Administration collects these taxes, even if the name and Social Security number do not match exactly.
According to research from the Institute on Taxation and Economic Policy, undocumented immigrants paid an estimated $25.7 billion into the Social Security system through payroll taxes during 2022. That figure is especially large considering that undocumented immigrants do not qualify for regular Social Security benefits. In most cases, the money simply stays in the Social Security trust funds.
Why Most Undocumented Immigrants Cannot Access Social Security Benefits
Social Security rules are clear about who can collect benefits. People must have worked “on the books” (meaning legally and officially with their own valid Social Security number) and must have lawful immigration status. Without legal immigration status or legal work authorization, a person cannot use work done under a borrowed or false number to build up the work record needed for Social Security.
This is not just a technical rule—the law strictly bars those without lawful presence from getting benefits, even if they paid in for many years. Only a very small group of undocumented immigrants ever manage to obtain legal status later, and only some of them can apply old earnings to claim Social Security. For everyone else, years of payroll taxes are paid in but never result in a monthly payment.
For example, the Bipartisan Policy Center explained that most undocumented immigrants never become eligible for Social Security benefits, unless laws change in the future or they join special programs granting legal status. Historically, amnesties or major legalizations have happened only rarely, and only for narrow groups.
The Net Impact: Unclaimed Funds and a Stronger Social Security Trust Fund
Because nearly all of the money paid by undocumented immigrants remains in the system and is never paid back out in benefits, these contributions create a large surplus for Social Security. In the words of several researchers, this situation means undocumented immigrants “strengthen the financial position of Social Security at least temporarily.”
Based on the data provided:
- Total unclaimed funds: More than a third of all tax dollars paid by undocumented immigrants go toward social insurance programs like Social Security. In California alone, undocumented immigrants contribute over $8.5 billion in state taxes each year, and a sizable portion is funneled into programs that they cannot access.
- Long-term balance: Using current numbers, the Social Security trust funds gain billions every year that will likely never be withdrawn as benefits by those who paid in. This positive effect is large enough to make a difference in estimates of when trust fund reserves might be depleted.
As the Institute on Taxation and Economic Policy points out, “More than a third… went toward funding social insurance programs that these individuals are barred from accessing because of their immigration status.”
Comparison Table: How Contributions and Benefits Differ by Group
To help explain how the system works for different groups, the following table compares who pays in, who can later get benefits, and the “net effect” on Social Security:
Group | Pays Into System | Eligible for Benefits? | Net Effect on Social Security |
---|---|---|---|
Native-born Americans | Yes | Yes | Balanced (most get what they paid in) |
Legal permanent residents | Yes | Yes | Slightly positive (often pay more than get due to shorter careers) |
Undocumented immigrants | Yes | No (rare exceptions) | Strongly positive surplus (funds stay in system) |
This means that undocumented immigrants, as a group, give much more to Social Security than they ever take out, unlike other groups who collect benefits that usually match or are a little less than what they contributed.
How Payroll Taxes Work and Why the System Is This Way
Payroll taxes fund Social Security and Medicare. Employers must deduct a percentage of each worker’s paycheck and send it directly to the Internal Revenue Service and Social Security Administration. For most Americans, this is a way to earn future benefits. For undocumented immigrants, these payments become a “silent tax”—they pay in year after year but rarely see any return.
The main reason the situation has grown so large is that millions of undocumented immigrants hold jobs and pay payroll taxes, mainly because employers need workers and are required by law to make these tax payments for everyone they hire. The Social Security trust fund receives the money, even if the worker cannot claim it.
Federal law does not allow the Social Security Administration to return money collected with unmatched or invalid Social Security numbers, so these payments stay in the trust fund, supporting payouts for those who are eligible.
A Closer Look at the Numbers: Billions Each Year
According to research and government reports:
- In 2022 alone, undocumented immigrants paid about $25.7 billion in Social Security payroll taxes.
- More than a third of all the tax dollars paid by undocumented immigrants—around $33.9 billion over several years—has gone directly to social insurance programs, including Social Security.
- In California, a state with the largest number of undocumented immigrants, these workers contribute $8.5 billion each year in state taxes.
These numbers come from the Institute on Taxation and Economic Policy as well as the California Budget Center.
Who Really Benefits from These Contributions?
Since most undocumented immigrants cannot get Social Security benefits, the extra money paid in through their payroll taxes stays in the system and helps pay for benefits for legal residents and citizens. This improves the program’s finances. In a time when experts worry about Social Security running short of money in future decades, these extra payments become even more important.
Some might wonder if there are hidden costs or if this money is used in other ways. The answer is clear—this surplus is currently used to help pay Social Security benefits each year, reducing the pressure on the trust funds.
Why Don’t Undocumented Immigrants Get Back What They Paid In?
The exclusion of undocumented immigrants from Social Security is based on existing federal law. To get retirement, disability, or family benefits, workers must prove they have legal status and have earned wages officially under a valid number. This rule is strict and tightly enforced.
Some undocumented immigrants might gain legal status in the future. In very rare cases, when people’s status changes and they can prove that their prior work was done under a valid number (assigned to them), they might claim credit for those years. However, most people working under false or borrowed numbers remain locked out forever.
For this reason, the system relies heavily on their payroll taxes but gives no direct return to these individuals or their families.
Possible Changes and What Could Shift the Balance
Changes in U.S. 🇺🇸 immigration laws—such as a broad legal immigration reform—could lead to more undocumented immigrants gaining lawful status. In that event, some workers might count old payroll taxes toward Social Security. Still, history shows that such large-scale changes are rare, and only a small number would likely benefit.
Unless and until laws change, undocumented immigrants will continue sending large sums to Social Security through payroll taxes, while receiving nothing directly in return. This situation effectively subsidizes the system for all other groups.
Challenges and Limitations in the Data
While the numbers reported here come from reliable sources, it’s important to note a few details:
- The exact amount paid by undocumented immigrants is hard to track because of the use of false or borrowed Social Security numbers.
- Estimates depend on surveys, payroll totals, and immigration statistics, not exact government counts.
- The share of undocumented immigrants’ payroll taxes going directly to Social Security is best measured over several years, not just one.
For more on data collection and how estimates are reached, readers can see the Social Security Administration’s official data page.
Why This Matters for Public Policy
The main question for Social Security and tax policy is: Should those who help pay for the system, but receive nothing back, continue to be left out? Some argue that their contributions deserve recognition. Others say that current law should stay the same.
What is clear is that the money undocumented immigrants pay in payroll taxes every year is a major plus for the system as it stands.
As reported by VisaVerge.com, this topic is important as lawmakers consider reforms to Social Security and immigration. Both systems are large and complex. Real facts about who pays, who collects, and who benefits should be part of every debate.
Key Points to Remember
- Undocumented immigrants paid about $25.7 billion into Social Security in a single year from payroll taxes.
- They are almost never eligible to claim Social Security benefits, unless their status changes—something that happens rarely.
- The surplus from their payroll taxes helps support the Social Security trust funds for everyone.
- About a third of all the taxes they pay go toward programs from which they are legally excluded.
- Policy discussions should take these facts into account when talking about social insurance and immigration.
The case of undocumented immigrants, payroll taxes, and Social Security makes it clear: many people who cannot get benefits still help keep the system strong. Their silent contributions are a key part of today’s Social Security landscape.

This Article in a Nutshell
Undocumented immigrants pay billions through payroll taxes into Social Security but cannot claim most benefits. In 2022, $25.7 billion was contributed, strengthening the trust funds for all Americans. This “silent tax” benefits the system’s finances while undocumented workers rarely see a return, highlighting substantive policy implications for lawmakers.
