Social Security is funded by workers and employers through payroll taxes, not from general tax revenue

Social Security does not come from a general government fund. Instead, it is funded by a specific tax called the Federal Insurance Contributions Act (FICA) tax, which is taken from paychecks. When you work, you and your employer each contribute a percentage of your wages to Social Security. Self-employed people pay both portions themselves. This money goes into a dedicated Social Security trust fund, separate from the rest of the federal budget.

The current FICA tax rate for Social Security is 12.4 percent of your wages — 6.2 percent comes from your paycheck, and your employer pays the other 6.2 percent. If you are self-employed, you pay the full 12.4 percent yourself, though you can deduct half of it on your taxes. This tax applies only to earnings up to a certain amount each year; that cap changes annually and is adjusted for inflation.

The money collected does not sit in an account with your name on it. Instead, it flows into the Social Security trust fund, which when ready pays out benefits to current retirees, disabled workers, and survivors. This is called a pay-as-you-go system — current workers fund current beneficiaries. When you retire, future workers' contributions will fund your benefits.

Key Takeaways

  • Social Security is funded by FICA payroll taxes: 6.2 percent from employees and 6.2 percent from employers, with self-employed people paying the full 12.4 percent.
  • The payroll tax applies only to earnings below an annual cap, which changes each year based on inflation.
  • Money collected from current workers when ready pays benefits to current retirees, disabled workers, and their survivors — not saved in individual accounts.
  • Social Security is a separate trust fund, not part of general federal income taxes or the broader government budget.
  • Your benefit amount is based on your lifetime earnings record, not on how much you personally paid in.

How much you and your employer contribute each year

Your Social Security contribution is calculated on your gross wages — the amount before taxes are taken out. If you earn $60,000 in a year, you pay 6.2 percent of that ($3,720), and your employer also pays 6.2 percent ($3,720). The total contribution is $7,440 per year for that income level.

However, there is a wage cap. In 2024, the cap is $168,600 — meaning you only pay Social Security tax on earnings up to that amount. If you earn $200,000, you pay the tax only on the first $168,600. This cap changes each year. High earners pay the same total amount as someone earning exactly at the cap, while lower-income workers pay a smaller dollar amount but the same percentage.

If you change jobs during the year, you may have multiple employers taking Social Security tax from your paychecks. You will not overpay — if your total contributions exceed the maximum for the year, you can claim the overage as a credit on your tax return.

What happens to the money you contribute

The Social Security Administration collects FICA taxes and deposits them into the Old-Age and Survivors Insurance (OASI) Trust Fund and the Disability Insurance (DI) Trust Fund. These are separate accounts, though they work the same way. Money flowing in is when ready used to pay benefits flowing out.

In recent years, the amount collected has been close to the amount paid out, with a small surplus building up in the trust funds. However, as more people retire and fewer workers contribute per retiree, the trustees project that the trust funds will eventually pay out more than they collect. When that happens — currently projected for 2033 for the OASI fund — the trust fund balance will begin to decline. At that point, incoming revenue alone would cover only about 80 percent of scheduled benefits unless Congress changes the law.

Your individual contributions do not sit in a personal account. The system is designed so that your taxes pay for current beneficiaries, and future workers' taxes will pay for you. This is why the program is sometimes called "social insurance" rather than a savings account.

How your benefit amount is determined

Your benefit is not based on how much you personally paid in. Instead, it is calculated using a formula that looks at your lifetime earnings record — the 35 highest-earning years of your work history. The Social Security Administration tracks your earnings each year through your employer's reports and your tax returns.

The formula is progressive, meaning lower-income workers receive a higher percentage of their average earnings as a benefit, while higher-income workers receive a lower percentage. This is intentional — Social Security is designed to replace a larger share of income for people who earned less during their working years.

You can view your earnings record and a benefit estimate by creating an account on ssa.gov. The estimate shows what you might receive at different ages — as early as 62, at your full retirement age (which depends on your birth year), or as late as 70. Waiting longer to claim generally means a larger monthly benefit.

Who else contributes to Social Security

Most workers in the United States pay into Social Security, but some groups are exempt. Federal employees hired before 1984 do not pay FICA taxes; instead, they contribute to a separate federal pension system called the Civil Service Retirement System (CSRS). Federal employees hired in 1984 or later do pay Social Security taxes.

Some state and local government employees are also exempt if they are covered by their own pension plans. However, many state and local workers do pay Social Security taxes in addition to their pension contributions.

Railroad workers pay into a separate system called the Railroad Retirement System, which is similar to Social Security but run independently. Certain religious groups can request exemption from self-employment taxes if they object on religious grounds, though this is rare.

Non-citizens who work in the United States with a valid work visa or green card must pay Social Security taxes just like citizens. Undocumented workers who work using an Individual Taxpayer Identification Number (ITIN) may also pay into the system, though they generally cannot claim benefits.

What happens if you do not work long enough to may have access to

To receive your own Social Security retirement benefit, you need at least 40 credits of earnings. A credit is earned for each quarter (three-month period) in which you earn at least a certain amount — in 2024, that amount is $1,730 per quarter. You can earn a maximum of four credits per year, so you need at least 10 years of work history to may have access to.

If you do not have 40 credits, you will not receive a retirement benefit based on your own work record. However, you may be able to receive a benefit as a spouse, ex-spouse, or survivor of someone who did work long enough. These benefits are also funded by FICA taxes but are calculated differently.

If you have some credits but not 40, those credits do not disappear. They remain on your record. If you return to work later, you can earn additional credits toward the 40 needed.

The trust fund and long-term solvency

Social Security's trust funds have a reserve balance built up over decades when more money came in than went out. This reserve allows the program to pay full benefits even when annual revenue falls short of annual costs. However, the reserve is not unlimited.

The Social Security trustees publish an annual report projecting when the trust funds will be depleted if no changes are made. As of the most recent reports, the OASI trust fund is projected to be depleted around 2033, and the DI trust fund has a longer horizon. When a trust fund is depleted, incoming revenue can still pay benefits, but only at the level that current tax revenue supports — which the trustees estimate would be roughly 80 percent of scheduled benefits.

Congress has the authority to change Social Security's funding through adjustments to the payroll tax rate, the wage cap, or the benefit formula. These are policy decisions, not automatic changes. Any changes would require new legislation.

Frequently Asked Questions

Does Social Security come from income taxes?

No. Social Security is funded by FICA payroll taxes, which are separate from federal income tax. Your FICA tax is taken from your paycheck and goes directly to the Social Security trust fund. Income tax goes to the general federal treasury and funds different government programs.

What if I work for multiple employers in one year?

Each employer will take Social Security tax from your paycheck. If your total earnings across all jobs exceed the annual wage cap, you may pay more Social Security tax than required. You can claim the overage as a credit on your federal tax return when you file.

Can I get back the money I paid into Social Security?

Social Security is not a savings account where you withdraw what you put in. It is insurance. Some people receive more in benefits than they paid in taxes, while others receive less — it depends on how long you live and your family situation. Spouses and survivors also receive benefits from your contributions.

Do self-employed people pay more into Social Security?

Self-employed people pay the full 12.4 percent Social Security tax themselves, rather than splitting it with an employer. However, they can deduct half of the self-employment tax on their income tax return, which provides some offset.

What happens to Social Security taxes if I do not work long enough to may have access to for benefits?

The money you paid goes into the trust fund and is used to pay current beneficiaries. You do not get a refund. However, if you have some credits, they remain on your record. You may also be able to receive benefits as a spouse or survivor based on someone else's work record.
