The Basic Steps to Apply for SSDI

You can apply for Social Security Disability Insurance (SSDI) in three ways: 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. The online application takes about 15 to 20 minutes if you have your documents ready. The phone line has wait times that vary by time of day; calling early morning on a weekday is usually faster. If you go in person, bring everything listed below — staff will not hold your hand through the process, but they will answer specific questions about what you need.

You do not need a lawyer to start the application. Many people file on their own the first time. You only pay a lawyer if you appeal and win; they take a percentage of your back pay, capped at $6,000 by federal law.

Key Takeaways

  • You can apply online, by phone, or at your local Social Security office, and the online route is usually fastest if you have your documents ready.
  • You will need your birth certificate, proof of citizenship or legal residency, tax returns or W-2s from the past two years, and medical records showing your condition and treatment history.
  • Social Security will ask for permission to contact your doctors directly; they will request your medical records themselves rather than asking you to collect them.
  • The initial decision typically arrives within three to six months, though this varies by your local office's workload.
  • If Social Security denies your claim, you can request reconsideration at no cost, and most people who appeal eventually receive benefits.

Documents You Need Before You Start

Gather these before you apply, whether online or by phone. Having them ready cuts your application time in half and reduces the chance you will have to resubmit later.

Identity and citizenship: Your Social Security card (or a record of your number), birth certificate, and proof of U.S. citizenship or legal residency. A passport, naturalization certificate, or green card all work. If you were born outside the U.S., bring the document that proves you are here legally.

Work history: Tax returns or W-2s from the past two years. If you are self-employed, bring your tax returns for the past two years. Social Security uses these to confirm you paid into the system and to calculate how much you might receive.

Medical records: You do not have to collect these yourself. During your application, you will sign a form giving Social Security permission to request records directly from your doctors, hospitals, and therapists. List the names, addresses, and phone numbers of every provider who has treated your condition. Include dates you saw them if you remember them. Social Security will contact them and ask for documentation of your diagnosis, treatment, test results, and how your condition limits your daily activities.

Work limitations: A list of what you cannot do because of your condition — for example, "cannot stand for more than 30 minutes" or "cannot concentrate for longer than one hour." You do not need a doctor to write this; you can describe it yourself. But if your doctor has written a statement about your limitations, bring that too.

What Happens During the Online Application

The online form at ssa.gov/applyfordisability walks you through sections in order. You cannot save and return later on most browsers, so set aside 20 to 30 minutes without interruption. Use a desktop or laptop if possible; the mobile version is slower.

The form asks for your personal information, work history, medical conditions, and the date your condition began to prevent you from working. Be as specific as possible about dates. If you cannot remember the exact month, write your best estimate — Social Security will verify it against your medical records anyway.

When the form asks for your doctors' information, enter every provider who has treated your condition, even if you have not seen them in years. Social Security pulls records from all of them to build a complete picture. If you list a provider and Social Security cannot locate them, they will contact you to ask for a corrected address.

At the end of the form, you will be asked to sign electronically. This is a legal signature; it means you swear the information is true. After you submit, you will receive a confirmation number. Write it down. You can use it to check the status of your application online.

Applying by Phone or In Person

If you call 1-800-772-1213, a representative will ask you the same questions as the online form, in the same order. The call usually takes 30 to 45 minutes. They will ask you to confirm your mailing address and will send you a summary of what you reported. Review it carefully when it arrives and call back if anything is wrong.

If you go to your local Social Security office, bring all your documents and a photo ID. You will fill out the same application form, either on a computer terminal or on paper. Staff will not fill it out for you, but they can answer questions about what each field means. Bring a list of your doctors' names and addresses; you can hand-write it if you do not have it printed.

In-person appointments are faster than calling if your office takes walk-ins, but many now require you to book online first. Check ssa.gov/locator to find your office and see whether appointments are available.

What Social Security Does After You Submit

After you apply, Social Security sends your case to a Disability information Services (DDS) office in your state. This is a separate agency that reviews medical evidence and decides whether you meet the legal definition of disability. You do not interact with DDS directly; Social Security handles all communication.

DDS will request your medical records from every provider you listed. This process takes four to eight weeks. While they wait for records, they may contact you by phone to ask follow-up questions about your work history or symptoms. Answer honestly and specifically. Vague answers like "I hurt all over" are less useful than "I have sharp pain in my lower back that gets worse when I sit for more than 20 minutes."

Once DDS has your records, a medical consultant and a disability examiner review them together. They check whether your condition matches one of Social Security's Listing of Impairments — a detailed list of conditions that automatically may have access to for benefits if you meet specific medical criteria. If your condition does not match a listing, they assess whether you can do any kind of work, even part-time or sedentary work. This is called a Residual Functional Capacity (RFC) assessment.

The initial decision usually arrives within three to six months, though some offices take longer. You will receive a letter in the mail explaining whether you were approved or denied, and why.

If Your Application Is Denied

About 65 to 70 percent of first-time applicants are denied. This does not mean you do not may have access to; it often means Social Security needs more or clearer medical evidence. You have the right to request reconsideration at no cost.

To request reconsideration, call 1-800-772-1213 or visit your local office within 60 days of the denial letter. Ask for a Reconsideration — this is a second review by a different examiner. You can submit new medical records, a statement from your doctor about why you cannot work, or additional information about your condition. Many people who are denied the first time are approved on reconsideration because they provide stronger medical evidence the second time.

If reconsideration is also denied, you can request a hearing before an Administrative Law Judge (ALJ). This is a formal process where you can present evidence and testify about your condition. Many people hire a lawyer at this stage, though you can represent yourself. If you win at the hearing, you receive back pay from the date you applied, minus the lawyer's fee.

Timeline and What to Expect

The process from application to initial decision typically takes three to six months. If you are denied and request reconsideration, add another two to four months. If you appeal to a hearing, add six to twelve months more, depending on how busy the judge's office is.

While you wait, you can work part-time and earn up to a certain amount without affecting your application. This amount changes each year; for 2024, it is $1,550 per month. If you earn more than that, Social Security may conclude you are not disabled and deny your claim. If you are working, tell Social Security during your application.

If you are approved, your first payment arrives the month after you are found disabled. If you applied in January and were approved in April, your first check covers May. Back pay — the money from when you applied until you were approved — is paid in a lump sum or in installments, depending on the amount.

Frequently Asked Questions

Do I need a doctor's letter to apply?

No. You can apply based on your own description of your condition and limitations. However, Social Security will request medical records from your doctors to verify your condition. If you do not have a doctor, you can still apply, but it will take longer because Social Security may need to refer you for a medical exam at their expense.

What if I have not worked in years?

You still may be able to receive SSDI if you worked long enough in the past to build up work credits. Most people need 40 credits total, with at least 20 earned in the last 10 years. You earn one credit for every $1,730 you earn in a year (this amount changes annually). Call 1-800-772-1213 and ask whether you have enough credits; they can tell you in one call.

Can I apply if I am still working?

Yes. You can work part-time and still apply. However, if you earn more than the monthly limit (currently $1,550), Social Security may deny your claim on the grounds that you are not disabled. Report your current work and income during your application.

How much will I receive each month?

Your monthly payment is based on your lifetime earnings record. The average SSDI payment is around $1,200 to $1,400 per month, but it varies widely. Social Security can estimate your payment before you apply; call 1-800-772-1213 and ask for a benefit estimate.

What if I disagree with the decision?

You have 60 days from the date on the decision letter to request reconsideration. This is free and does not require a lawyer. If reconsideration is denied, you can request a hearing before a judge. Most people who appeal eventually receive benefits, especially if they provide stronger medical evidence the second time.
