Who Can File for SSDI

You can file for Social Security Disability Insurance if you have worked long enough under Social Security and have a medical condition that meets the Social Security Administration's definition of disability. The SSA does not care what your condition is called by your doctor or what diagnosis you carry — it only cares whether your condition prevents you from doing substantial work and is expected to last at least 12 months or result in death.

You do not have to be unable to work at all. You have to be unable to do "substantial gainful activity" — which means earning more than a set monthly amount. In 2024, that amount is $1,550 per month (or $2,590 if you are blind). If you earn less than that, you may still file. If you earn more, the SSA will likely deny your claim, regardless of your condition.

There is no age limit on who can file. You can file at 18, at 45, or at 64. However, you must have earned enough work credits in the years before you became disabled. The number of credits you need depends on your age when you became disabled — younger workers need fewer credits than older workers.

Key Takeaways

  • You must have worked under Social Security long enough to earn the required work credits for your age at the time you became disabled.
  • Your medical condition must prevent you from doing substantial work (earning more than $1,550 per month in 2024) and must be expected to last at least 12 months or result in death.
  • You can file at any age, but the SSA will verify your work history through your Social Security record, not through a resume or employer letter.
  • If you are filing based on someone else's work record (as a spouse, ex-spouse, or adult child), you must meet different rules tied to that person's record, not your own.
  • You can file online, by phone, or in person at your local Social Security office; the SSA does not charge a fee to file.

Work Credits and Age Requirements

Social Security tracks your work history in work credits, not years. You earn one credit for each $1,730 of wages you report to Social Security in 2024 (the amount changes each year). You can earn a maximum of four credits per year, regardless of how much you earn.

The number of credits you need to file for SSDI depends on how old you were when your disability began. If you became disabled at 24, you need 12 credits. If you became disabled at 31, you need 20 credits. If you became disabled at 42, you need 20 credits. If you became disabled at 62 or older, you need 30 credits. The SSA has a work credit calculator on its website that shows the exact requirement for your age.

You also must have earned at least 20 of your required credits in the 10 years before you became disabled. This rule is called the "recent work requirement." If you stopped working at 30 and became disabled at 50, you would not meet this rule, even if you had earned 30 credits total in your lifetime.

Filing Based on Your Own Work Record

If you file based on your own work record, the SSA will pull your earnings history directly from its database. You do not need to bring pay stubs, tax returns, or letters from employers. The SSA already has this information because your employer reported your wages to Social Security when you were working.

When you file, you will be asked to describe when your disability began. The SSA calls this your onset date. This date matters because it determines which work credits you need and which medical evidence the SSA will review. If you say your disability began in January 2023, the SSA will look at your work history through January 2023 and will ask for medical records from around that time.

If you have worked on and off, or if you have worked for cash and did not report it to Social Security, you may not have enough credits. You can check your work credit record by creating an account on ssa.gov and viewing your Social Security Statement. If your record is wrong, you can ask the SSA to correct it, but you will need documentation (old pay stubs, W-2 forms, or a letter from your employer).

Filing as a Spouse, Ex-Spouse, or Adult Child

You can file for SSDI based on someone else's work record if you are their spouse, ex-spouse, or adult child. You do not need your own work credits to file this way. Instead, the SSA will look at the primary earner's record to see if they have enough credits.

If you are filing as a spouse, you must be at least 62 years old, or you must be any age and caring for a child under 16 (or a disabled child of any age). If you are filing as an ex-spouse, you must have been married for at least 10 years, be at least 62, and be unmarried. If you are filing as an adult child, you must be between 18 and 19 (or up to 22 if you are a full-time high school student), or you must be disabled and have become disabled before age 22.

When you file as a dependent, your benefit amount is a percentage of the primary earner's benefit. The SSA will calculate what the primary earner would receive, then pay you a portion of that amount. If the primary earner is not yet receiving benefits, the SSA will calculate what they would receive if they filed.

Medical Conditions That Meet SSA Standards

The SSA maintains a list called the Blue Book that describes medical conditions it recognizes as disabling. The list includes conditions like cancer, heart disease, arthritis, mental illness, back injuries, and many others. However, having a condition on the list does not automatically mean you will be approved. The SSA still has to decide that your specific condition prevents you from working.

If your condition is not on the list, you can still file. The SSA will evaluate whether your condition, combined with your age, education, and work history, prevents you from doing any work. This is called a medical-vocational allowance. It is harder to win this way, but it is possible.

The SSA will ask for medical records from your doctors, hospitals, and mental health providers. You do not have to pay for these records — you can ask your providers to send them to the SSA for free. The SSA will review the records to see whether your condition is severe enough and whether it is expected to last at least 12 months.

Citizenship and Residency Requirements

You must be a U.S. citizen or a lawful permanent resident to file for SSDI. If you are a citizen, you can file from anywhere. If you are a lawful permanent resident, you can also file from anywhere in the United States.

If you are not a citizen or permanent resident, you cannot file for SSDI. Some non-citizens may be able to file for Supplemental Security Income (SSI), which is a different program with different rules. You can ask the SSA whether you are may be able to access for SSI when you contact them about SSDI.

How and Where to File

You can file for SSDI online at ssa.gov, by calling the SSA's national number at 1-800-772-1213, or by visiting your local Social Security office in person. There is no fee to file. The SSA does not charge for applications, and no private company needs to file for you.

If you file online, you will create an account and fill out the process on the SSA's website. The process usually takes 15 to 20 minutes. If you file by phone, a representative will ask you questions and fill out the process for you. If you file in person, you will bring documents to prove your identity and citizenship, and a representative will help you complete the form.

After you file, the SSA will send you a notice confirming that your process was received. The SSA will then ask you to send in medical records and other documents. You have about 10 days to respond, though you can ask for more time. The SSA will review your case and send you a decision letter, usually within 3 to 6 months.

Frequently Asked Questions

Can I file if I am still working?

Yes, you can file while working. However, if you are earning more than $1,550 per month (in 2024), the SSA will likely deny your claim based on substantial gainful activity. If you are earning less than that amount, you can file and the SSA will review your medical condition.

Do I need a lawyer to file?

No, you do not need a lawyer to file. You can file on your own for free. However, if your claim is denied and you appeal, some people hire a lawyer to help them. Lawyers who handle SSDI cases charge a fee only if you win, and the fee is limited by law to 25 percent of your back pay.

What happens if I file and I am denied?

If you are denied, you can appeal. You have 60 days from the date of the denial letter to file an appeal. Most people file a request for reconsideration, which means the SSA will review your case again with new medical evidence. If you are denied again, you can request a hearing before an administrative law judge.

Can I file if I am receiving unemployment benefits?

Yes, you can file for SSDI while receiving unemployment. However, if you are receiving unemployment, the SSA may question whether you are truly unable to work. You should explain to the SSA why you cannot work, even though you were receiving unemployment benefits.

What if my work history is incomplete because I worked under the table?

If you worked for cash and did not report it to Social Security, those years will not count toward your work credits. You can only use work that was reported to Social Security. If you have old pay stubs or a letter from your employer, you can ask the SSA to add those earnings to your record, but this is difficult and requires strong documentation.
