What Social Security is and who it covers

Social Security is a federal insurance program run by the Social Security Administration (SSA). It pays monthly benefits to workers who have reached retirement age, to workers who become disabled before retirement, to the surviving family members of workers who die, and to some spouses and children of beneficiaries. The program is funded through payroll taxes that workers and employers pay during working years.

You become covered by Social Security the moment you start working and your employer (or you, if self-employed) begins withholding Social Security tax from your pay. You do not have to do anything to be covered — it happens automatically. The SSA keeps a record of your earnings under your Social Security number, and those earnings determine how much you will receive later.

Social Security is not a savings account where your own taxes sit waiting for you. It is a pay-as-you-go system: taxes paid by today's workers fund benefits for today's retirees and disabled people. When you retire or become disabled, benefits paid to you come from taxes being collected now.

Key Takeaways

  • Social Security provides monthly income to retirees at age 62 or later, to workers who become disabled, and to their family members — the amount depends on your earnings record and when you start collecting.
  • You earn Social Security credits through work, and you need 40 credits (roughly 10 years of work) to be covered for retirement benefits.
  • Your benefit amount grows if you delay claiming past your full retirement age, which ranges from 66 to 67 depending on your birth year.
  • You can check your earnings record and estimate your future benefits by creating an account at ssa.gov.
  • The SSA processes claims through local offices and online, and the process typically takes several weeks to several months.

How you earn Social Security credits and coverage

Social Security measures your work history in credits. In 2024, you earn one credit for every $1,730 in wages or self-employment income, up to a maximum of four credits per year. The dollar amount that earns a credit changes each year — it was lower in past years and will be higher in future years.

To be covered for retirement benefits, you need 40 credits total. This usually means about 10 years of work, but the years do not have to be consecutive. If you worked five years, then took time off, then worked five more years, you would have 40 credits. The SSA counts credits from all your jobs combined.

To be covered for disability benefits, you need fewer credits — the exact number depends on your age when you become disabled. A worker who becomes disabled at 24 needs only 6 credits; a worker disabled at 31 needs 20 credits; a worker disabled at 42 or older needs 20 credits earned in the 10 years before disability. Surviving family members of a worker who dies are covered if the worker had earned at least 6 credits in the three years before death.

Retirement benefits and when you can start collecting

You can begin collecting Social Security retirement benefits as early as age 62, but your monthly payment will be permanently reduced — typically by 25 to 30 percent compared to what you would receive at full retirement age. Your full retirement age (also called normal retirement age) depends on your birth year: it ranges from 66 to 67 for people born between 1943 and 1960, and is 67 for people born in 1960 or later.

If you wait past your full retirement age to claim, your benefit grows by about 8 percent per year until age 70. This means a person born in 1960 with a full retirement age of 67 who waits until 70 will receive about 24 percent more per month than they would at 67. The choice between claiming early, at full retirement age, or delaying depends on your health, life expectancy, and financial needs — there is no single right answer for everyone.

Your benefit amount is based on your 35 highest-earning years. If you worked fewer than 35 years, the SSA counts zero-earning years, which lowers your average. If you worked more than 35 years, only your 35 best years count. The SSA calculates your Primary Insurance Amount (PIA) using a formula that replaces a higher percentage of lower earnings and a lower percentage of higher earnings, which means the system is designed to replace a larger share of income for lower-wage workers.

Disability and survivor benefits

If you become unable to work due to a medical condition that is expected to last at least 12 months or result in death, you may be covered for Social Security Disability Insurance (SSDI). You do not have to be retired — disability benefits are available to workers of any age who have earned enough credits. The SSA has a strict definition of disability: you must be unable to do any substantial work, not just your previous job.

The SSA also pays benefits to your family members if you are disabled, retired, or deceased. A spouse can receive benefits at age 62 (or at any age if caring for a child under 16), a former spouse can receive benefits if the marriage lasted at least 10 years, and unmarried children can receive benefits until age 19 (or 19 if still in high school, or indefinitely if disabled before age 22). Each family member's benefit is a percentage of your benefit amount, but the total paid to your whole family cannot exceed about 150 to 180 percent of your own benefit.

How to check your earnings record and estimate your benefits

The SSA maintains a record of all wages and self-employment income reported to it under your Social Security number. You can view this record and check for errors by creating a my Social Security account at ssa.gov. You will need your Social Security number, email address, and a way to verify your identity — usually a phone number or financial account.

Once you have an account, you can see your complete earnings history, a statement showing your estimated retirement benefit at different ages, your estimated disability benefit, and your estimated family benefits. The estimates assume you continue working and earning at your current rate until retirement age. If your earnings history is wrong — for example, if an employer reported your wages under the wrong name or number — you should contact the SSA to correct it. Corrections usually must be made within three years, three months, and 15 days of the year the wages were earned.

You can also request a printed Social Security Statement by mail through your my Social Security account, though the online version is faster and more current.

How to claim benefits

You can file for Social Security benefits online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. Online filing is usually the fastest option and allows you to track your claim status. You will need documents such as your birth certificate, proof of citizenship or legal residency, and tax returns or W-2 forms if the SSA needs to verify your earnings.

The SSA typically processes retirement claims within two to three weeks if you file online, though some claims take longer if the SSA needs to verify information or if there are complications. Disability claims take much longer — usually three to six months for an initial decision, and longer if you appeal a denial. You can file for benefits up to four months before you want them to start, which means you can file at 61 and a half if you plan to claim at 62.

If you are already receiving benefits and want to change your claim — for example, to suspend benefits and let them grow, or to claim spousal benefits — you will need to contact the SSA directly. Not all changes are available to all people; the rules depend on your age and when you originally filed.

Taxes on benefits and other income considerations

If your income is low, your Social Security benefits are not taxed. If your income is higher, up to 50 percent or 85 percent of your benefits may be subject to federal income tax, depending on your total income and filing status. The SSA sends you a form each year showing how much you received, which you use when filing your tax return.

If you claim benefits before your full retirement age and continue working, your benefits will be reduced by $1 for every $2 you earn above an annual limit (the limit changes each year and was $23,400 in 2024). Once you reach your full retirement age, there is no earnings limit — you can work and collect your full benefit. This rule applies only to earned income from work; it does not explore to investment income, pensions, or other sources.

Frequently Asked Questions

Can I change my mind after I start collecting Social Security?

If you filed for benefits within the last 12 months, you can withdraw your claim and repay all benefits received, which restarts your claim and allows you to file again later at a higher amount. After 12 months, you cannot withdraw. You may be able to suspend your benefits at full retirement age to let them grow, but the rules for suspension changed in 2015 and depend on your birth year.

What happens to my benefits if I move out of the United States?

If you are a U.S. citizen, you can receive benefits anywhere in the world. If you are not a U.S. citizen, the rules are more complex and depend on your country of residence and immigration status. Contact the SSA before moving to confirm your situation.

How much will I receive each month?

Your benefit amount depends on your earnings history, your age when you claim, and family circumstances. The average retirement benefit in 2024 was around $1,900 per month, but individual benefits range widely. Your my Social Security account shows your estimated benefit based on your actual earnings record.

What if I never worked or worked very little?

You need 40 credits to be covered for retirement benefits. If you have fewer than 40 credits, you are not covered for your own retirement benefit. However, you may be covered as a spouse or surviving family member of someone who is covered, depending on your age and relationship.

Can I receive Social Security and a pension from a government job at the same time?

If you earned a pension from work not covered by Social Security (such as some federal, state, or local government jobs), your Social Security benefit may be reduced by the Government Pension Offset or Windfall Elimination Provision, depending on your situation. The reduction is not automatic — it applies only if you meet specific conditions. The SSA can tell you whether it affects you.
