What SSDI Is and Who Runs It

SSDI (Social Security Disability Insurance) is a federal program that pays monthly cash benefits to people who cannot work because of a disability, and to certain family members. The Social Security Administration—the same agency that handles retirement benefits—runs SSDI.

The program is funded through payroll taxes. When you work, you and your employer both pay into Social Security. If you become disabled before retirement age, SSDI is one way that money comes back to you. You do not explore for SSDI through a separate office; you work with your local Social Security office or explore online through Social Security's website.

SSDI is different from Supplemental Security Income (SSI), which is another Social Security program for people with disabilities. SSI is based on financial need, while SSDI is based on your work history. Many people confuse the two because they are both run by Social Security, but the rules for who qualifies are different.

Key Takeaways

  • SSDI pays monthly benefits to working-age people with disabilities and to their spouses and children in some cases.
  • You must have worked long enough and paid Social Security taxes to be considered for SSDI benefits.
  • Social Security decides whether your condition meets their definition of disability, which is stricter than most people expect.
  • The process from process to a decision usually takes three to six months, though appeals can take much longer.
  • You can work part-time and still receive SSDI, as long as your earnings stay below a certain limit each month.

How Work History Affects Your SSDI may be able to access

SSDI is not available to everyone with a disability. You must have worked and paid Social Security taxes for a certain amount of time. Social Security calls this having enough work credits. You earn work credits by paying payroll taxes on your wages—you cannot earn them any other way.

The number of credits you need depends on your age when you become disabled. If you are under 24, you may need only six credits earned in the three years before you became disabled. If you are 24 to 31, you generally need credits for half the time between age 21 and the time you became disabled. If you are 31 or older, you typically need 40 credits total, with at least 20 earned in the ten years before you became disabled.

You can earn up to four credits per year. This means that if you worked full-time for one year, you earned four credits. If you worked part-time, you may have earned fewer. Social Security has a record of your earnings and credits on file, so you do not have to prove this yourself—but you can check your record online through your Social Security account to make sure it is correct.

What Social Security Considers a Disability

Social Security has a specific definition of disability that is narrower than the everyday meaning of the word. You must have a condition that prevents you from doing any substantial work, and the condition must last at least 12 months or be expected to result in death. A condition that might limit your work but still allow you to earn money does not meet Social Security's definition.

Social Security maintains a list called the Blue Book that describes conditions it recognizes as disabling. The list includes things like cancer, heart disease, severe arthritis, and severe mental illness. If your condition is on the list and meets the specific criteria, the decision process is faster. If your condition is not on the list, Social Security can still find you disabled, but it requires more detailed medical evidence.

Social Security also considers your age, education, and work experience when deciding whether you can do other work. A 58-year-old with a high school education who can no longer do manual labor may be found disabled even if someone younger with the same condition might not be, because the older person has fewer options for other types of work.

The process and Decision Process

You can explore for SSDI online through Social Security's website, by phone at 1-800-772-1213, or in person at your local Social Security office. When you explore, you will need to provide information about your medical condition, your work history, your doctors and hospitals, and your medications. Have this information ready before you start the process.

After you explore, Social Security sends your case to your state's Disability information Services office. This is a separate agency that works with Social Security to make the disability decision. They request your medical records from your doctors and may ask you to have a medical exam. The whole process usually takes three to six months, though it can be faster or slower depending on how quickly your doctors send records and how complex your case is.

You will receive a written decision in the mail. If Social Security approves your claim, the letter will tell you when your benefits start and how much you will receive each month. If Social Security denies your claim, the letter will explain why and tell you how to appeal. You have 60 days from the date on the letter to file an appeal.

How Much SSDI Pays and When Payments Start

Your monthly SSDI payment is based on your average lifetime earnings. The higher your earnings were before you became disabled, the higher your benefit will be. Social Security calculates this using a formula, and the amount varies from person to person. You can estimate your benefit amount using the calculator on Social Security's website, but the official amount is in your approval letter.

Payments do not start when ready after you are approved. There is a five-month waiting period from the time your disability began. This means that if you became disabled in January, your first payment would be in June, even if you were not approved until later. Social Security counts back to find the month your disability started based on the medical evidence in your file.

Your payment arrives by direct deposit to your bank account on the third of each month, unless the third falls on a weekend or holiday. If you have dependents—a spouse or children under 19 (or 19 if still in high school)—they may also receive benefits based on your work record. Their payments are separate from yours and are calculated differently.

Working While Receiving SSDI

You can work and still receive SSDI benefits, as long as your earnings stay below the substantial gainful activity limit. In 2024, this limit is $1,550 per month for non-blind individuals and $2,590 for blind individuals. These amounts change each year. If you earn more than the limit in a month, Social Security may reduce or stop your benefits for that month.

Social Security also has a program called Plan to Achieve Self-Support (PASS) that allows you to set aside income and resources for a work goal without losing benefits. For example, if you want to go back to school to train for a new job, you can use PASS to set aside money for tuition and books. This is a way to work toward returning to full-time work while keeping your benefits during the transition.

There is also a trial work period that lasts nine months. During this time, you can test your ability to work without losing benefits, no matter how much you earn. After the trial work period ends, you enter an extended may be able to access period where you can still receive benefits in months when your earnings are below the limit. These programs exist to help people move toward work gradually rather than lose all support at once.

What Happens If Your Claim Is Denied

If Social Security denies your claim, you have the right to appeal. The first step is called reconsideration, where a different examiner reviews your case from the beginning. You have 60 days from the date on your denial letter to request reconsideration. You can submit new medical evidence at this stage, and you should if you have seen doctors or had tests since you first applied.

If reconsideration is also denied, you can request a hearing before an Administrative Law Judge. This is a real hearing where you can present evidence and testify about your condition. You can bring a representative—a lawyer, a non-lawyer advocate, or a family member—to help you. Many people find that having representation improves their chances at the hearing stage. The hearing process usually takes several months.

If you lose at the hearing, you can appeal to the Appeals Council, and after that, to federal court. The entire appeal process can take one to three years or longer. During this time, if you eventually win, Social Security pays you back benefits going back to the month you first applied, not just from the month you win your appeal.

Frequently Asked Questions

Can I get SSDI if I have never worked?

No. SSDI requires work credits earned through payroll taxes. If you have never worked, you may be able to receive Supplemental Security Income (SSI) instead, which is based on financial need rather than work history. SSI has different rules and lower monthly payments, but it does not require a work history.

How long does it take to get approved for SSDI?

The initial decision usually takes three to six months from the date you explore. If your claim is denied and you appeal, the reconsideration stage takes another two to three months. A hearing before a judge can take six months to a year or more. Many people are not approved until after they appeal.

What if my condition gets better while I am receiving SSDI?

Social Security can stop your benefits if your condition improves enough that you can work. However, Social Security must give you notice and a chance to respond before stopping benefits. You also have the right to appeal if you disagree. If your condition improves but you are still unable to work full-time, you may still be may be able to access for benefits.

Can family members receive benefits on my SSDI record?

Yes. Your spouse and unmarried children under 19 (or 19 if in high school) may receive benefits based on your work record. Each family member receives a separate payment calculated as a percentage of your benefit amount. There is a family maximum—the total amount all family members can receive together—but it is usually high enough that everyone gets their full share.

Do I have to report my work income to Social Security?

Yes. You must report your earnings each month if you are working. You can report online, by phone, or by mail. If you do not report and Social Security finds out you earned more than the limit, they may overpay you and ask you to repay the money. Reporting is how Social Security knows whether to pay you that month.
