Social Security taxes fund retirement, disability, and survivor benefits

Social Security tax is a federal payroll tax that comes out of your paycheck. The money does not go into a personal account with your name on it. Instead, it goes into a single federal fund that pays benefits to people who are retired, disabled, or whose family members have died. You pay this tax on wages you earn from a job, and your employer pays a matching amount.

The tax rate is 12.4 percent of your wages — you pay half (6.2 percent) and your employer pays the other half. If you are self-employed, you pay both halves yourself. The tax applies only to wages up to a certain limit, which changes each year. In 2024, that limit is $168,600, meaning you stop paying Social Security tax once your annual wages reach that amount.

Social Security taxes are separate from income tax and Medicare tax, though all three come out of your paycheck. The Social Security Administration tracks how much you have paid over your lifetime, and that record determines how much you can receive in benefits later.

Key Takeaways

  • Social Security tax is 6.2 percent of your wages (your employer matches it), and it funds retirement, disability, and survivor benefits for millions of Americans.
  • The tax applies only to wages below an annual limit, which was $168,600 in 2024 and increases most years.
  • Your Social Security record is based on how much you paid in taxes over your working years, not on a personal savings account.
  • Self-employed workers pay both the employee and employer portions, totaling 12.4 percent of their net self-employment income.

How the money is used right now

Social Security taxes collected today pay benefits to current retirees, disabled workers, and surviving family members of workers who have died. The program does not save your taxes for your own retirement — it is a pay-as-you-go system. Money coming in from workers pays money going out to beneficiaries when ready.

In any given month, the Social Security Administration sends checks to roughly 67 million people. About 42 million are retired workers, 8 million are disabled workers, and the rest are family members receiving survivor benefits. The amount each person receives depends on how much they paid into the system during their working years and when they started taking benefits.

The Social Security Trust Fund holds a reserve to cover months when benefit payments exceed incoming tax revenue. This reserve has been shrinking for several years, but the program continues to pay full benefits to everyone who is may have access to to them.

What determines your future benefit amount

The Social Security Administration keeps a record of your earnings for every year you work and pay Social Security tax. When you reach retirement age or become disabled, your benefit is calculated based on your highest 35 years of earnings. The longer you work and the more you earn, the higher your benefit will be.

You can start receiving retirement benefits as early as age 62, but your monthly payment will be smaller than if you wait. If you wait until age 70, your monthly benefit will be larger. The age at which you are may have access to to full benefits (called your full retirement age) depends on the year you were born and ranges from 66 to 67 for people born in 1943 or later.

If you become unable to work due to a serious medical condition, you may be may have access to to disability benefits based on your work record, even if you have not yet reached retirement age. Family members of disabled workers, retirees, and deceased workers may also receive benefits based on that worker's record.

Self-employed workers and Social Security tax

If you are self-employed, you pay Social Security tax through self-employment tax on your net business income. You pay both the employee portion (6.2 percent) and the employer portion (6.2 percent), for a total of 12.4 percent. You report this on your federal tax return using Schedule SE.

Self-employed income counts toward your Social Security record the same way wages do. The Social Security Administration uses your self-employment tax payments to calculate your future benefit amount. You can deduct half of your self-employment tax as a business expense on your income tax return, which reduces your overall tax burden.

What happens if you do not pay Social Security tax

If you work without paying Social Security tax, those years do not count toward your benefit record. This can happen if you work for an employer who does not withhold taxes, work under the table, or work for certain government agencies that have their own retirement systems instead of Social Security.

Years with no reported earnings count as zero when your benefit is calculated. Since your benefit is based on your highest 35 years, missing years of earnings can lower your eventual benefit amount. If you have fewer than 10 years of work history with reported earnings, you will not be may have access to to retirement benefits based on your own record, though you may be may have access to to benefits as a spouse or family member.

How to check your Social Security record

You can create an account on ssa.gov to view your earnings record and see an estimate of your future benefits. The Social Security Administration sends this information in a statement that shows your reported earnings for each year you worked. Checking your record periodically helps you catch errors — if your employer reported your earnings incorrectly, you can request a correction.

You need to report any errors within three years, three months, and 15 days of the year the earnings were reported. If you find a mistake, contact the Social Security Administration with proof of your actual earnings, such as tax returns or W-2 forms. Correcting errors early ensures your benefit calculation is accurate.

Frequently Asked Questions

Do I pay Social Security tax on all my income?

No. Social Security tax applies only to wages from employment and net self-employment income, up to an annual limit. In 2024, that limit is $168,600. Income from investments, rental property, or other sources does not count toward Social Security tax.

Can I get back the Social Security taxes I paid?

Not directly. Social Security is insurance, not a savings account. You receive benefits based on your work record and age, not based on the exact amount you paid in. Some people receive more than they paid in; others receive less. Family members can also draw benefits on your record.

What if I worked in another country?

Work history in other countries generally does not count toward U.S. Social Security benefits unless you paid U.S. Social Security tax on those wages. Some countries have agreements with the United States that allow work in both countries to count, but the rules vary. Contact the Social Security Administration for details about your specific situation.

Do I have to pay Social Security tax if I am a student?

Yes, if you earn wages from a job. Student status does not exempt you from Social Security tax. However, certain work-study positions and on-campus employment may be exempt depending on your school and employer.

What happens to my Social Security taxes if I die before retirement?

Your family members may be may have access to to survivor benefits based on your work record. A spouse, children under 19 (or 23 if in school), and dependent parents may receive monthly benefits. Even if you never collected retirement benefits yourself, your taxes can still support your family.
