Social Security tax comes out of your paycheck automatically, and your employer matches it
Social Security tax is a federal payroll tax that funds the Social Security program. If you work as an employee, your employer deducts 6.2 percent of your gross pay and sends it to Social Security. Your employer also pays 6.2 percent on your behalf — that is 12.4 percent total. If you are self-employed, you pay both portions yourself, which comes to 15.3 percent of your net earnings.
The tax appears on your pay stub as "FICA" (Federal Insurance Contributions Act) or "Social Security tax". It is separate from Medicare tax, which is 1.45 percent from you and 1.45 percent from your employer. Together, FICA taxes fund both Social Security and Medicare.
There is a wage cap: in 2024, you pay Social Security tax only on earnings up to $168,600. Income above that amount is not taxed for Social Security. This cap changes each year based on national wage trends. Medicare tax, by contrast, has no cap — you pay it on all earnings.
Key Takeaways
- Social Security tax is 6.2 percent of your paycheck if you are an employee, with your employer paying an equal 6.2 percent.
- Self-employed workers pay 15.3 percent of net earnings because they cover both the employee and employer portions.
- The tax applies only to earnings below an annual cap, which was $168,600 in 2024 and increases yearly.
- Your Social Security taxes fund retirement, disability, and survivor benefits — the amount you pay determines your future benefit amount.
- You can view your lifetime earnings and estimated benefits on your Social Security statement at ssa.gov.
How much you pay depends on your income and employment status
If you earn $50,000 a year as an employee, you pay $3,100 in Social Security tax annually ($50,000 × 0.062). Your employer pays another $3,100. If you earn $200,000, you pay Social Security tax only on $168,600 (the 2024 cap), which is $10,453.20 — not on the full amount.
Self-employed workers calculate their tax on net profit after business expenses. If your net self-employment income is $50,000, you owe $7,650 in Social Security and Medicare combined (15.3 percent). You can deduct half of this amount from your income taxes, which slightly reduces the overall burden.
Certain groups do not pay Social Security tax. Federal employees hired before 1984, some state and local government workers, and nonresident aliens on student visas are typically exempt. If you work for a nonprofit or religious organization that has not elected to participate, you may also be exempt.
Where your Social Security taxes actually go
Social Security taxes do not go into a personal account with your name on it. Instead, the money goes into a general trust fund that pays current benefits to retirees, disabled workers, and survivors of deceased workers. In 2024, about 67 million people received Social Security benefits, and the program paid out roughly $1.3 trillion in benefits that year.
The Social Security Administration publishes annual reports showing how much money came in from taxes and how much went out in benefits. When tax revenue exceeds benefit payments, the surplus goes into reserves. When benefit payments exceed tax revenue — which has been the case since 2021 — the program draws from those reserves.
The program is designed so that current workers fund current retirees. This is sometimes called a "pay-as-you-go" system. Your taxes today pay for your parents' or grandparents' benefits, and future workers' taxes will pay for yours.
How your tax history affects your future benefits
Social Security calculates your benefit amount based on your highest 35 years of earnings. The more you earn and the longer you work, the higher your monthly benefit will be. If you work fewer than 35 years, zeros are counted for the missing years, which lowers your average.
You need 40 work credits to receive retirement benefits. You earn one credit for each $1,705 of earnings in 2024 (the amount changes yearly). Most people earn four credits per year, so you need about 10 years of work to may have access to. Disability and survivor benefits have different credit requirements — some can be earned in fewer years.
The Social Security Administration keeps a record of your earnings under your Social Security number. You can check your lifetime earnings history and see an estimate of your future benefits by creating an account at ssa.gov and viewing your Social Security statement. This statement shows what you have paid in and what you might receive at different retirement ages.
What happens if you work while receiving Social Security
If you claim Social Security before your full retirement age and continue working, your benefits may be reduced. In 2024, Social Security reduces your benefit by $1 for every $2 you earn above $23,400 per year. The year you reach full retirement age, the reduction is $1 for every $3 earned above $62,160, but only for earnings before the month you reach full retirement age.
Once you reach your full retirement age, you can earn as much as you want with no reduction to your benefits. You still pay Social Security tax on those earnings, and those additional earnings can increase your future benefit amount if they are among your highest 35 years.
Part-time work, self-employment income, and wages all count toward the earnings limit. Unearned income — such as interest, dividends, or rental income — does not count.
Understanding the difference between what you pay and what you receive
Social Security is not a savings account. You do not get back exactly what you paid in. Some people receive more than they contributed; others receive less. The amount you receive depends on when you claim, how long you live, and your family situation.
A person who claims at 62 receives smaller monthly payments but starts collecting sooner. A person who waits until 70 receives larger monthly payments but collects for fewer years. On average, the total lifetime benefit is similar, but the monthly amount differs significantly.
Married couples, widows, widowers, and children of deceased or disabled workers may also receive benefits based on someone else's work record. A spouse can receive up to 50 percent of the primary worker's benefit, and children can receive up to 75 percent. These family benefits do not reduce the primary worker's benefit.
How to check your Social Security tax record
Visit ssa.gov and create a my Social Security account to view your earnings record and benefit estimate. You will need your Social Security number, date of birth, email address, and a phone number. The account shows your year-by-year earnings history and flags any discrepancies.
If you find an error — such as earnings that were not credited to your account — you can report it to Social Security. You have a limited time to correct errors, so it is worth checking your record every few years, especially early in your career.
You can also request a paper statement by mail if you do not have internet access. Call the Social Security Administration at 1-800-772-1213 to request one.
Frequently Asked Questions
Can I get a refund of Social Security taxes I paid?
No. Social Security taxes are not refundable. Once you pay them, the money goes into the trust fund. You receive benefits later based on your earnings record and when you claim, not as a return of what you paid.
What happens to my Social Security taxes if I die before claiming benefits?
Your taxes do not go back to your family. However, your family members — spouse, children, or parents — may be may have access to to survivor benefits based on your work record. These benefits are separate from any refund and depend on your family's age and relationship to you.
Do I pay Social Security tax on tips or bonuses?
Yes. Tips and bonuses are considered wages and are subject to Social Security tax. Your employer should report them on your W-2 form, and the tax is deducted from your pay.
Why does the Social Security wage cap exist?
The cap was set by law and is adjusted yearly. It limits the maximum amount of earnings subject to the tax. High earners pay a smaller percentage of their total income in Social Security tax than lower earners do, which is why the cap is sometimes debated in policy discussions.
Can I opt out of paying Social Security tax?
No, with rare exceptions. Most workers are required to pay. The exceptions are certain federal employees hired before 1984, some state and local government workers, and nonresident aliens on specific visa types. If you think you may be exempt, contact the Social Security Administration.
