How to File for SSDI: The Basic Route

You file for SSDI through the Social Security Administration (SSA), not through your state or a private organization. You can start the process online at ssa.gov, by phone at 1-800-772-1213, or by visiting your local Social Security office in person. The online process takes about 15 to 20 minutes if you have your documents ready; the phone route takes longer but a representative walks you through it.

When you file, you are creating a record with SSA that you are claiming disability. This record is what triggers the medical review process. You do not need a lawyer to file — SSA will accept your process whether you have one or not — but many people hire a representative later if their claim is denied.

The process itself asks for your work history, your medical conditions, the doctors and hospitals that have treated you, and the dates of that treatment. You will need your Social Security number, birth certificate, and a list of medications and providers. Have those details ready before you start, because SSA cannot process an incomplete process.

Key Takeaways

  • You file directly with the Social Security Administration online, by phone, or in person; no state agency or intermediary is involved.
  • SSA will ask for your work history, medical records, and the names and dates of all doctors who have treated your condition.
  • After you file, SSA sends your case to a state Disability information Services office, which makes the medical decision within 30 to 90 days in most cases.
  • If you are denied, you have the right to appeal, and most people who appeal with new medical evidence or a representative are reconsidered.
  • You can work part-time while your claim is pending and still receive benefits if you are found disabled, as long as your earnings stay below the substantial gainful activity limit.

What Documents You Need Before You File

SSA will ask for proof of your identity, your work history, and your medical condition. Bring your Social Security card, birth certificate, and driver's license or passport. If you do not have a birth certificate, SSA can help you get one, but it will delay your process.

For your work history, have your last W-2 or tax return ready, or a list of employers and the dates you worked for each. SSA already has your earnings record on file, but they want you to confirm it is correct. If you were self-employed, bring tax returns for the last two years.

For your medical condition, write down the names and phone numbers of every doctor, hospital, and mental health provider who has treated you. Include the dates of your first visit and your most recent visit to each. SSA will request your medical records directly from these providers, so accuracy matters — if you misspell a name or get the phone number wrong, SSA may not be able to find your records.

You do not need to gather the actual medical records yourself. SSA will request them from your providers once your process is filed. However, if you have recent test results, imaging reports, or specialist letters that clearly show your condition, you can upload them to your online process or bring them to your local office. This can speed up the review.

The Medical Review Process After You File

Once SSA receives your process, they send your case to your state's Disability information Services (DDS) office. This is a state agency that works under contract with SSA to make the medical decision. DDS requests your medical records from all the providers you listed and reviews them to see whether your condition meets SSA's definition of disability.

The review usually takes 30 to 90 days, though it can take longer if your medical records are hard to obtain or if your condition is complex. You will not hear from DDS directly in most cases — SSA will contact you if they need more information, such as the name of a provider you forgot to list or clarification about when your condition started.

DDS looks at whether your condition prevents you from doing any work that exists in the national economy, not just your old job. They use SSA's medical guidelines, called the Blue Book, to evaluate your condition. If your medical records show that your condition meets or equals a listing in the Blue Book, you will be found disabled. If your records do not meet a listing, DDS will assess your remaining work capacity — what you can still do — and decide whether work exists that you could perform.

What Happens If Your Claim Is Denied

About 65 to 70 percent of initial applications are denied. This does not mean you cannot receive SSDI — it means SSA did not find enough medical evidence in your records to support a disability finding at that stage. The most common reason for denial is that your medical records do not show ongoing treatment or that the records do not describe your condition in enough detail.

If you are denied, you have the right to appeal. You have 60 days from the date on your denial letter to request reconsideration. At reconsideration, SSA sends your case back to DDS with any new medical evidence you have gathered since your first process. If you have seen a doctor, had new test results, or started a new treatment since you filed, include those records in your appeal.

Many people hire a representative at the appeal stage. A representative can be a lawyer, a non-lawyer advocate, or a disability advocate. They charge a fee only if you win, and the fee is capped at 25 percent of your back pay (the money SSA owes you from the date you filed). If you cannot afford a representative, you can appeal on your own, and SSA will still consider your case.

The Hearing Stage and Beyond

If you are denied again at reconsideration, you can request a hearing before an Administrative Law Judge (ALJ). This is a real hearing, held either in person or by video, where you can present evidence and answer questions about your condition and your ability to work. You can bring witnesses, such as a family member or a doctor, to testify about your condition.

The ALJ decision usually comes within 60 to 90 days after your hearing. If the ALJ denies you, you can appeal to the Appeals Council, which is the next level within SSA. If the Appeals Council denies you or does not change the ALJ's decision, you can file a lawsuit in federal court. Very few cases reach federal court, but it is an option if you believe SSA made a legal error.

The entire process from initial process to a final decision can take two to three years if you appeal all the way through. However, if you win at any stage — initial process, reconsideration, or hearing — SSA will pay you back to the date you filed, minus any representative fee.

Working While Your Claim Is Pending

You can work part-time while your SSDI claim is being reviewed. SSA does not stop your claim because you are earning money. However, if you earn more than the substantial gainful activity (SGA) limit, SSA may assume you are not disabled and deny your claim.

The SGA limit changes each year. In 2024, it is $1,550 per month for non-blind individuals and $2,590 for blind individuals. If you earn less than this amount, you can continue working without affecting your claim. If you earn more, SSA will look at whether your earnings are consistent and whether you are doing the work yourself or with significant help due to your condition.

If you are found disabled and begin receiving SSDI benefits, you can continue to work under SSA's work incentive programs. The Trial Work Period allows you to earn any amount for nine months without losing benefits. After that, you enter the Extended may be able to access Period, during which you can work and earn above the SGA limit for up to 36 months while still receiving benefits in months when your earnings fall below SGA. These programs are designed to help you test whether you can return to work without losing your safety net.

Timeline and What to Expect at Each Stage

The timeline varies depending on whether you appeal and how complex your medical condition is. Here is what a typical path looks like:

  • Filing to initial decision: 30 to 90 days. SSA sends your case to DDS, which reviews your medical records and makes a decision.
  • Denial to reconsideration decision: 30 to 90 days. You submit new medical evidence, and DDS reviews your case again with a different examiner.
  • Reconsideration denial to hearing request: You have 60 days to request a hearing. The hearing is usually scheduled 60 to 120 days after you request it.
  • Hearing to ALJ decision: 60 to 90 days after your hearing.
  • Appeals Council review: 60 to 120 days if you appeal the ALJ decision.

During this entire time, you are not receiving benefits. However, if you eventually win, SSA will pay you back to the date you filed, minus any representative fee. This back pay can be substantial — sometimes $10,000 to $30,000 or more, depending on how long the process took.

Frequently Asked Questions

Can I file for SSDI if I am still working?

Yes. You can file while working as long as your earnings are below the substantial gainful activity limit ($1,550 per month in 2024 for non-blind individuals). If you earn more than this, SSA may deny your claim, but you can still file and appeal if you believe you cannot sustain that level of work long-term.

Do I need a lawyer to file for SSDI?

No. You can file and appeal on your own. However, a representative can help you gather medical evidence, prepare for a hearing, and present your case to an ALJ. Representatives are paid only if you win, and their fee is capped at 25 percent of your back pay.

What if my doctor says I am disabled but SSA denies my claim?

SSA makes its own disability information based on medical evidence in your records, not on your doctor's opinion alone. If your doctor has written a detailed report explaining why you cannot work, include that in your appeal. If your doctor has not documented your condition thoroughly, ask them to write a report or provide recent test results and treatment notes for your reconsideration.

How much back pay will I receive if I win?

SSA pays you back to the date you filed your process, minus a five-month waiting period. If your claim takes two years to win, you will receive approximately 19 months of back pay. The amount depends on your Primary Insurance Amount (PIA), which is based on your lifetime earnings record.

Can I file for SSDI if I have never worked?

No. SSDI requires that you have worked and paid Social Security taxes. If you have never worked, you may be able to file for Supplemental Security Income (SSI) instead, which is a needs-based program. SSI has different rules and does not require a work history.
