What Social Security Disability Insurance Is

Social Security Disability Insurance (SSDI) is a federal program that pays monthly benefits to people who cannot work because of a medical condition expected to last at least 12 months or result in death. You receive SSDI based on your own work history and the taxes you or a family member paid into Social Security — not based on how much money you have now.

SSDI is different from Supplemental Security Income (SSI), which is a needs-based program for people with disabilities who have little income or resources. Some people receive both, but they are separate programs run by the Social Security Administration.

The amount you receive each month depends on your age when you became disabled and how much you earned during your working years. There is no set dollar amount — your benefit is calculated from your individual earnings record.

Key Takeaways

  • SSDI pays monthly benefits based on your work history, not your current financial need, and requires a medical condition that prevents substantial work for at least 12 months.
  • You must have worked long enough and recently enough in jobs covered by Social Security to be found may be able to access for SSDI.
  • The Social Security Administration reviews your medical evidence and work history; the process typically takes three to six months for an initial decision.
  • If your initial request is denied, you can ask for reconsideration, request a hearing before an administrative law judge, or appeal further.
  • Once approved, you continue to receive benefits as long as your condition prevents you from working and you report changes to Social Security.

Who Can Receive SSDI

To receive SSDI, you must have a medical condition that meets Social Security's definition of disability. This means the condition prevents you from doing substantial work — currently defined as earning more than a certain monthly amount (this amount changes yearly). The condition must be expected to last at least 12 months or result in death.

You also must have worked long enough in jobs covered by Social Security. The number of work credits you need depends on your age when you became disabled. Generally, you need 40 credits total, with at least 20 earned in the 10 years before you became disabled. A credit is earned based on your annual income; in 2024, you earn one credit for each $1,730 of wages (the amount changes yearly).

Social Security maintains a list of conditions that automatically meet the disability standard, called the Compassionate Allowances list. These include certain cancers, severe heart conditions, and advanced Alzheimer's disease. If your condition is on this list and you meet the work requirements, your case may move faster.

How to Start the Process

You can begin the SSDI process online at ssa.gov, by phone at 1-800-772-1213 (TTY 1-800-325-0778), or in person at your local Social Security office. You will need to provide your Social Security number, birth certificate, proof of citizenship or legal residency, and your W-2 forms or tax returns from the past year.

You will also need to submit medical evidence. This includes records from doctors, hospitals, clinics, or therapists who have treated you. Social Security will request these records directly from your providers if you give permission, or you can gather them yourself. The stronger and more recent your medical documentation, the faster your case can be reviewed.

After you submit your request, Social Security sends it to your state's Disability information Services office. This office reviews your medical evidence and work history and makes the initial decision. You will receive a written notice in the mail explaining whether you were found may be able to access.

What Happens During the Review

The Disability information Services office compares your medical condition against Social Security's rules. They look at whether your condition prevents you from doing your past work and whether it prevents you from doing other work that exists in the national economy. They also consider your age, education, and work skills.

The review typically takes three to six months, though it can take longer if Social Security needs more medical evidence. You can check the status of your case online using your my Social Security account at ssa.gov, or by calling 1-800-772-1213.

If Social Security needs more information from you or your doctors, they will send you a letter asking for it. Responding quickly to these requests helps move your case forward. If you do not respond, Social Security may make a decision based on the information they already have.

If Your Request Is Denied

If Social Security denies your request, you have the right to appeal. You have 60 days from the date on the denial letter to ask for reconsideration. This means Social Security will review your case again, usually with a different examiner.

If reconsideration is also denied, you can request a hearing before an administrative law judge. This is a formal proceeding where you can present evidence and testimony. Many people hire a lawyer or representative at this stage; representatives are paid only if you win, and the fee is limited by law.

After the hearing, if you are still denied, you can appeal to the Appeals Council, and then to federal court. Each step has its own important date, which Social Security explains in the denial letter.

Your Monthly Benefit Amount

Your SSDI benefit is based on your Primary Insurance Amount (PIA), which is calculated from your average earnings over your working years. Social Security uses a formula that weights your earlier earnings more heavily. The formula changes yearly.

You can see an estimate of your benefit amount before you request SSDI by creating a my Social Security account at ssa.gov. The account shows your earnings record and an estimate based on your current age and work history.

If you have family members — a spouse, ex-spouse, or children under 19 (or 19 if still in high school) — they may also receive benefits based on your work record. These family benefits do not reduce your payment; each family member receives their own benefit.

Work Incentives and Continuing Benefits

Once you are approved for SSDI, you can work and still receive benefits during a trial work period. This allows you to test your ability to work without when ready losing your benefits. After the trial work period ends, Social Security continues to pay benefits for a grace period while you are still working, then stops payments if your earnings exceed the substantial work level.

Social Security also offers programs like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) that let you deduct certain costs from your earnings when Social Security calculates whether you are working at a substantial level. These programs are designed to help you return to work without losing benefits when ready.

You must report changes to Social Security, including changes in your medical condition, work activity, living situation, or marital status. You can report changes online, by phone, or in person. Failing to report changes can result in overpayments that you may have to repay.

Frequently Asked Questions

How long does it take to get approved for SSDI?

The initial decision typically takes three to six months. If you are denied and appeal, reconsideration takes another two to three months. A hearing before a judge can take one to two years, depending on how busy the judge's office is. Cases on the Compassionate Allowances list may move faster.

Can I work while receiving SSDI?

Yes. You have a nine-month trial work period during which you can earn any amount and still receive full benefits. After that, if your earnings stay below the substantial work level (currently around $1,550 per month in 2024), you continue to receive benefits. Above that level, benefits stop, though you may may have access to for extended benefits under work incentive programs.

What if my condition improves?

Social Security may schedule a medical review to check whether you still meet the disability standard. If your condition has improved enough that you can work at a substantial level, your benefits will stop. You have the right to appeal any decision that your condition has improved.

Do I have to pay taxes on SSDI benefits?

SSDI benefits may be taxable depending on your total income. If you have other income in addition to SSDI, part of your benefits may be subject to federal income tax. Social Security sends you a form each year showing how much you received, which you use when filing your tax return.

What happens to my SSDI if I reach full retirement age?

Your SSDI automatically converts to retirement benefits at your full retirement age, but the payment amount stays the same. You continue to receive the same monthly amount for the rest of your life. This is not a separate program; it is a change in the category under which you receive benefits.
