The Basic Steps to File for SSDI

You file for Social Security Disability Insurance (SSDI) by submitting a claim to the Social Security Administration (SSA). You can start the process online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. The SSA will ask for medical records, work history, and details about your condition. After you submit, the SSA sends your case to your state's Disability information Services (DDS) office, which makes the decision about whether you meet the medical criteria for disability.

The entire process typically takes three to six months, though some cases take longer. You will receive a decision letter in the mail. If you are approved, your benefits begin the month after you have been disabled for five full calendar months — this is called the five-month waiting period. If you are denied, you have the right to appeal.

Key Takeaways

  • You can file online at ssa.gov, by phone at 1-800-772-1213, or at your local Social Security office; online is usually fastest.
  • The SSA will need your medical records, a list of doctors and hospitals you have seen, your work history, and details about your condition and how it limits you.
  • Your state's Disability information Services office, not the SSA, makes the medical decision on your claim.
  • Even if you are approved, benefits do not start until the month after your five-month waiting period ends.
  • If you are denied, you can appeal; most people who appeal with new medical evidence or a lawyer have better outcomes than those who do not.

Filing Online, by Phone, or In Person

The fastest way to file is online at ssa.gov/applyfordisability. You create an account, answer questions about your medical condition and work history, and upload documents. The online form takes 15 to 20 minutes if you have your information ready. The SSA will send you a confirmation number and tell you what happens next.

If you prefer to file by phone, call 1-800-772-1213 Monday through Friday, 7 a.m. to 7 p.m. your local time. A representative will walk you through the questions and may ask you to mail in documents afterward. If you file in person, go to your local Social Security office with your documents. You can find the nearest office at ssa.gov/locator. In-person filing can take longer because offices have limited hours and may have a wait, but some people prefer it if they need help understanding the questions.

What Documents and Information You Need

Before you file, gather the following: your Social Security number, birth certificate, proof of citizenship or legal residency (passport or green card), and a list of all doctors, hospitals, and mental health providers you have seen in the past year. Include their names, addresses, and phone numbers. The SSA will contact them directly to get your medical records.

You will also need your work history for the past 15 years, including the names of employers, dates you worked, and the type of work you did. If you are self-employed, bring tax returns. Have your bank account information ready if you are approved, because the SSA will deposit your benefits directly. If you do not have all of this information, you can still file — the SSA will help you gather it — but having it ready speeds up the process.

How the SSA Decides Your Case

After you file, the SSA sends your case to your state's Disability information Services office. This is a state agency that works with the SSA to review medical evidence. The DDS office does not make a quick decision; they order medical records from every doctor and hospital you listed, review them carefully, and sometimes order a consultative exam (a free medical exam paid for by the SSA) if they need more information.

The DDS uses a five-step process to decide whether you meet the definition of disability under Social Security law. They look at whether you are working and earning more than $1,550 per month (the current substantial gainful activity limit, which changes yearly), whether your condition is severe enough to significantly limit your ability to work, whether your condition matches or equals a condition on the SSA's list of impairments, whether you can do your past work, and whether you can do any other work that exists in the economy. If you fail any step, you are denied. If you pass all steps, you are approved.

The Five-Month Waiting Period

If you are approved, your benefits do not start when ready. SSDI has a five-month waiting period, which means you must have been disabled for five full calendar months before you receive any payment. For example, if the SSA decides you became disabled in January, your waiting period ends May 31, and your first check arrives in June.

This waiting period is built into the law and cannot be waived. During this time, you are approved and your case is closed, but you receive no money. After the five months end, you become may have access to to benefits, and the SSA begins paying you. If you have been working part-time or receiving other benefits during your waiting period, the SSA will let you know how that affects your payment amount.

What Happens If You Are Denied

About 65 to 70 percent of people are denied on their first process. A denial does not mean you cannot receive SSDI — it means the SSA decided you did not meet the medical criteria at the time they reviewed your case. You have the right to appeal, and you have 60 days from the date on your denial letter to request an appeal.

There are four levels of appeal: reconsideration (the SSA reviews your case again with new evidence), a hearing before an administrative law judge, the Appeals Council, and federal court. Most people who appeal with new medical evidence — such as recent test results, imaging, or a detailed letter from their doctor explaining how their condition has worsened — have better outcomes than those who do not. Many people also hire a disability lawyer at the hearing stage. Lawyers are paid only if you win, and they take a percentage of your back pay (usually 25 percent, capped at $7,200).

What to Do While Your Case Is Being Decided

While the SSA is reviewing your case, keep seeing your doctors and keep records of all appointments, test results, and treatments. This medical evidence is what the DDS uses to make their decision. If your condition changes or worsens, tell your doctors and ask them to document it in your medical records.

Do not stop working or quit your job while waiting for a decision, because the SSA looks at your work history and current earnings to decide whether you are disabled. If you are working, keep track of how much you earn each month. If you are approved and working, you may be able to continue working part-time under SSDI work incentives, which allow you to earn money without losing your benefits when ready. The SSA has rules about how much you can earn before your benefits are reduced or stopped.

Frequently Asked Questions

Can I file for SSDI if I have never worked?

No. SSDI is based on your own work history and the taxes you have paid into Social Security. If you have never worked or have very little work history, you may be able to file for Supplemental Security Income (SSI) instead, which is a different program for people with low income and resources. SSI has no work history requirement.

How much does it cost to file for SSDI?

Filing for SSDI is free. The SSA does not charge you to submit a claim or to appeal a denial. If you hire a lawyer to help with your appeal, the lawyer is paid from your back pay if you win, not from your pocket upfront.

What if I am still working when I file?

You can file while working. The SSA looks at your average earnings over time, not just your current job. If you earn more than $1,550 per month (the 2024 limit), the SSA may decide you are not disabled because you are doing substantial gainful activity. However, if your earnings are lower or if you can show that your condition prevents you from working consistently, you may still be approved.

How long does it take to get my first payment after I am approved?

Your first payment arrives the month after your five-month waiting period ends. If you are approved in March, your waiting period ends July 31, and you receive your first check in August. The SSA deposits payments directly into your bank account on the third of each month (or the closest business day).

Can I file for SSDI on behalf of someone else?

You can help someone file, but they must sign the process themselves or authorize you in writing. If the person is unable to sign (for example, if they are in a coma or have severe cognitive impairment), you may need to become their representative payee or legal guardian, which requires court approval or SSA paperwork.
