The Basic Rule: You Must Have Worked and Paid Into Social Security

Social Security Disability Insurance (SSDI) is only available to people who have worked and paid Social Security taxes. You cannot receive SSDI based on someone else's work history, and you cannot receive it if you have never worked. The program is fundamentally different from Supplemental Security Income (SSI), which does not require work history at all.

The amount you paid into the system through payroll taxes matters less than whether you paid at all. A person who worked for two years and a person who worked for thirty years both become insured if they meet the work credit requirement for their age. The specific number of credits you need depends on how old you are when you become disabled.

If you are currently working and earning income, you can still have SSDI. The program does not exclude people who work part-time or who are trying to return to work. What matters is whether you meet the work credit threshold and whether your medical condition meets the program's definition of disability.

Key Takeaways

  • You must have worked and paid Social Security taxes to receive SSDI; no work history means you do not meet the basic requirement, though you may be able to receive SSI instead.
  • The number of work credits you need depends on your age when you become disabled, ranging from 6 credits for people under 24 to 40 credits for people 62 and older.
  • You earn work credits by paying Social Security taxes on wages or self-employment income, and you can earn up to four credits per year regardless of how much you earn.
  • Spouses, ex-spouses, and children of a disabled worker can receive benefits based on that worker's record, even if they have never worked themselves.
  • If you do not have enough work credits, you may still receive SSI if your income and resources fall below the program's limits.

How Work Credits Connect to Your Age

The Social Security Administration uses a sliding scale based on your age when you become disabled. Younger workers need fewer credits because they have had less time to work. The system assumes that a person who becomes disabled at 24 has not had the same opportunity to build a work history as someone who becomes disabled at 50.

If you are under 24, you typically need only 6 work credits earned in the three years before you became disabled. If you are between 24 and 31, you need one credit for every year since you turned 21, with a minimum of 6 credits. At 31 and older, you need 20 credits earned in the ten years before you became disabled, plus additional credits based on your age.

The oldest threshold is 40 credits total, which applies to people 62 and older. Most people who have worked full-time for ten years will have 40 credits. You do not need to have earned all your credits recently—only that you have the total number required for your age group.

What Counts as a Work Credit

You earn work credits by paying Social Security taxes on wages from a job or on net income from self-employment. In 2024, you earn one credit for every $1,550 in wages or self-employment income, up to a maximum of four credits per year. This means that if you earn $6,200 in a year, you will receive four credits for that year, even though you earned more than the threshold.

The dollar amount that triggers a credit changes every year based on national wage averages. The Social Security Administration publishes the current year's amount on its website. If you worked part-time or had irregular income, you may still have earned credits in years when you earned less than the full threshold—you straightforward would have earned fewer than four credits that year.

Credits earned decades ago still count. There is no time limit on how old your credits can be. A person who worked steadily from age 22 to age 32, then stopped working entirely, still has all the credits from those ten years of work. Those credits do not expire if you later become disabled.

Family Members Who Can Receive Benefits on Your Record

If you are approved for SSDI, your spouse, ex-spouse, and children may also receive benefits based on your work record. They do not need to have worked themselves. Each family member receives a separate payment, though the total amount paid to your entire family cannot exceed a certain percentage of your benefit amount.

Your spouse can receive benefits at any age if they are caring for a child under 16 who is also receiving benefits on your record. If your spouse is not caring for a child, they can receive benefits starting at age 62, or at any age if they are disabled themselves. An ex-spouse can receive benefits on your record if you were married for at least ten years, you are at least 62 years old (or disabled), and you have been divorced for at least two years.

Your unmarried children can receive benefits until age 19 if they are in high school full-time, or until age 18 if they are not in school. Children who are disabled before age 22 can receive benefits for life, regardless of age. Grandchildren and step-children may also be may be able to access under specific circumstances, though the rules are more restrictive.

People Who Cannot Receive SSDI

You cannot receive SSDI if you have never worked and paid Social Security taxes. This includes people who have only received income from SSI, welfare, unemployment benefits, or family support. It also includes people who worked only in jobs that did not require Social Security tax contributions, such as certain government positions with their own retirement systems.

You cannot receive SSDI if your medical condition does not meet the Social Security Administration's definition of disability. The program defines disability narrowly: your condition must prevent you from doing any substantial work, and it must be expected to last at least twelve months or result in death. A condition that limits your ability to do your previous job, but not all work, does not meet this standard.

You cannot receive SSDI while you are incarcerated in a federal, state, or local prison or jail. Your benefits stop the first full month you are incarcerated and resume the month after your release. If you are on probation or parole, you can still receive benefits.

The Difference Between SSDI and SSI

SSDI is based on your work history; SSI is based on your current income and resources. If you do not have enough work credits for SSDI, you may still receive SSI if your monthly income is below a certain amount and your total resources (savings, property, vehicles) are below $2,000 for an individual or $3,000 for a couple. SSI has no work requirement at all.

SSI is also available to people who are blind or over 65, not just people who are disabled. The income and resource limits are the same across all three categories. SSI payments are typically smaller than SSDI payments because SSI is a needs-based program funded by general tax revenue, while SSDI is funded by Social Security taxes paid by workers.

You can receive both SSDI and SSI at the same time if your SSDI payment is very small. The Social Security Administration will pay your full SSDI amount, then add SSI to bring your total income up to the SSI payment level if you meet SSI's income and resource requirements. This is called concurrent benefits.

How to learn about You Have Enough Work Credits

The Social Security Administration maintains a record of your work history and the credits you have earned. You can view this record by creating an account on ssa.gov and accessing your Social Security Statement. The Statement shows your earnings history year by year and the number of credits you have earned.

You can also call the Social Security Administration at 1-800-772-1213 to ask about your work credits. Have your Social Security number ready. A representative can tell you how many credits you have and how many you need based on your age. If you believe there is an error in your record—for example, if you worked in a year that does not appear on your Statement—you can request a correction.

If you are explore for SSDI, the Social Security Administration will verify your work credits as part of the process process. You do not need to prove your credits yourself; the agency has access to your tax records and employer reports. However, checking your Statement before you explore can help you understand whether you meet the basic requirement.

Frequently Asked Questions

Can I receive SSDI if I worked under the table or for cash?

No. SSDI requires that you paid Social Security taxes on your income, which means your employer reported your wages to the Social Security Administration. Work paid in cash without tax reporting does not create work credits. Self-employment income counts only if you reported it on your tax return and paid self-employment tax.

What if I worked in another country before moving to the United States?

Work you did outside the United States generally does not count toward SSDI work credits, with limited exceptions for people who worked in countries that have a Social Security agreement with the United States. The Social Security Administration can tell you whether your country has such an agreement. Work you did in the United States counts regardless of your immigration status at the time.

Can my adult child receive benefits on my SSDI record?

Only if your child became disabled before age 22. Children who are disabled before that age can receive benefits for life based on a parent's SSDI record. Adult children who became disabled after age 22 cannot receive benefits on a parent's record, though they may be able to receive SSDI on their own work record if they have worked and paid Social Security taxes.

If I am denied SSDI for not having enough work credits, can I appeal?

You can appeal the decision, but the appeal will not change the work credit requirement—it is a fixed rule based on your age. However, you can appeal if you believe the Social Security Administration made an error in counting your credits. You can also ask about SSI, which has no work requirement and may help you if your income and resources are low enough.

Do military service credits count toward SSDI?

Military service credits are added to your Social Security record only if you served on active duty before 1968, or if you served after 1967 and paid Social Security taxes on your military pay. Most service members after 1967 paid these taxes automatically, so their service counts. You can check your Social Security Statement to see whether military credits appear on your record.
