The Basic Steps to File for SSDI or SSI

You can file for Social Security disability benefits 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. Online filing is fastest — you can complete the process in one sitting and receive a confirmation number when ready. Phone filing takes longer because a representative must ask every question, but it works if you cannot use a computer or need language support. In-person filing at your local office is useful if you have documents to show or need help understanding what information to bring.

The Social Security Administration (SSA) will ask for your medical records, work history, and proof of citizenship or legal residency. You do not need to gather everything before you start — you can file first and send records later — but having them ready speeds up the review. The SSA has a checklist on its website showing exactly what documents help your case, organized by condition type.

After you file, the SSA sends your case to your state's Disability information Services (DDS) office, which is a separate government agency that makes the medical decision. DDS will request your medical records directly from your doctors and hospitals. This process usually takes three to six months, though it can take longer if your medical history is complex or if DDS needs more information from your doctors.

Key Takeaways

  • You can file online, by phone, or in person; online is fastest and you can start at ssa.gov without an appointment.
  • The SSA asks for medical records, work history, and proof of citizenship, but you can file first and send records later.
  • Your case goes to your state's Disability information Services office, which makes the medical decision separate from Social Security.
  • The review process usually takes three to six months, and you will receive a written decision by mail.
  • If you are denied, you have the right to appeal, and most people who appeal with new medical evidence are eventually approved.

What Documents You Need Before You Start

Bring or have ready your Social Security card, birth certificate, and proof of U.S. citizenship or legal residency (passport, green card, or visa). You will also need your driver's license or state ID, tax returns or W-2 forms from the past two years, and a list of all jobs you have held in the past 15 years with approximate start and end dates. If you are self-employed, bring tax returns showing your income.

For your medical case, gather the names and addresses of all doctors, hospitals, and mental health providers who have treated you for your condition. Write down the dates you saw each one and what they treated you for. If you have recent test results, imaging reports, or hospital discharge summaries, those help, but the SSA will request official records directly from your providers — you do not need to collect originals yourself.

If you have already been denied for disability by another program (such as a private insurance company or workers' compensation), bring that denial letter. It does not prevent you from filing with Social Security, but it can provide useful medical information to DDS.

Filing Online: The Fastest Route

Go to ssa.gov and click "explore for Disability." You will create a my Social Security account if you do not already have one. The online form takes 15 to 30 minutes and asks about your medical condition, when it started, how it affects your work, your work history, and your family situation. You can save your progress and return later if you need to look up information.

At the end, you will receive a confirmation number and a date when the SSA will contact you. Keep this number — you will need it if you call Social Security with questions about your case. The SSA will mail you a receipt within two weeks confirming that your process was received.

After you file online, the SSA will send you a list of medical records they need. You can upload documents through your my Social Security account, mail them, or ask your doctor's office to send them directly to the SSA. The address for mailing records is on the letter the SSA sends you.

Filing by Phone or In Person

To file by phone, call 1-800-772-1213 Monday through Friday, 7 a.m. to 7 p.m. your local time. Wait times are usually shorter early in the morning or late in the afternoon. A representative will ask you the same questions as the online form, which takes 30 to 45 minutes. Have your Social Security card, birth certificate, and a list of your doctors and employers nearby when you call.

To file in person, find your local Social Security office at ssa.gov/locator or call the main number above. You do not need an appointment for disability filing — walk in during business hours. Bring the same documents you would have ready for a phone call. In-person filing is useful if you need help reading or understanding questions, or if you have documents to show the representative.

Whether you file by phone or in person, you will receive a receipt showing the date you filed. This date is important because it determines when your benefits would start if you are approved.

What Happens After You File

Within one to two weeks, the SSA sends you a receipt letter confirming your process was received and listing the medical records they need. At the same time, your case is transferred to your state's Disability information Services office. DDS contacts your doctors and hospitals to request your medical records — you do not need to do this yourself, though you can ask your providers to send records faster if you want to.

DDS reviews your medical records and decides whether your condition meets Social Security's definition of disability: it must prevent you from working for at least 12 months or result in death. DDS does not look at your age, education, or how hard you have worked — only whether your medical condition is severe enough. This review usually takes two to four months, but can take longer if your medical history is complicated or if DDS needs clarification from your doctors.

You will receive a written decision by mail. If you are approved, the letter explains when your benefits start and how much you will receive. If you are denied, the letter explains why and tells you how to appeal.

Understanding the Medical Decision Process

Disability information Services uses a five-step process to review your case. First, they check whether you are working and earning more than $1,550 per month (this amount changes yearly). If you are, they usually deny the case because Social Security considers this "substantial work activity." Second, they look at whether your medical condition is severe — meaning it causes more than minor limitations. Third, they check whether your condition matches one of Social Security's medical listings, which are detailed descriptions of conditions that automatically may have access to for disability.

If your condition does not match a listing, DDS moves to step four: they assess your "residual functional capacity," which is a detailed description of what physical and mental work you can still do despite your condition. They use your medical records and sometimes order a consultative examination (a one-time appointment with a doctor chosen by DDS) to determine this. Finally, in step five, they decide whether you can do any other work that exists in the national economy given your age, education, work history, and functional capacity.

Most denials happen at step five, when DDS decides you could do other work even though you cannot do your previous job. This is where appeals with new medical evidence often succeed — if you can show your condition has worsened or that you cannot perform the work DDS says you can do, an appeals judge may reverse the decision.

What to Do If You Are Denied

You have 60 days from the date on your denial letter to file an appeal. Do not wait — if you miss this important date, you must file a new process and start over. The appeal process has three levels: reconsideration, hearing before an administrative law judge, and appeals council review.

At reconsideration, a different DDS examiner reviews your case and any new medical evidence you submit. This is your chance to send updated medical records, test results, or a new statement from your doctor explaining why you cannot work. Reconsideration takes two to three months. If you are denied again, you can request a hearing before an administrative law judge (ALJ), which is the most important step — most people who reach a hearing with strong medical evidence are approved.

To request a hearing, file form ssa-561-u2 within 60 days of your reconsideration denial. You can represent yourself or hire a disability lawyer. Lawyers are paid only if you win, and their fee is capped at 25 percent of your back pay (the money owed from when you first filed). The hearing usually happens four to six months after you request it, and the ALJ will ask you questions about your medical condition and work history.

Frequently Asked Questions

Can I file for disability while I am still working?

Yes, you can file while working, but if you earn more than $1,550 per month (2024 amount), Social Security will likely deny your case at the first step. However, filing while working establishes your process date, which matters for back pay if you are later approved. If your income drops below the limit before your decision, you may be approved.

How much back pay will I receive if I am approved?

Back pay is calculated from your process date minus five months (the waiting period). If you filed in January and were approved in September, you would receive back pay from August (January plus five months) through September. The exact amount depends on your Primary Insurance Amount, which is based on your work history and earnings record.

Do I need a lawyer to file for disability?

You do not need a lawyer to file your initial process or to request reconsideration. Many people file on their own and are approved. A lawyer becomes more useful if you are denied and need to appeal to a hearing, because the hearing process is more formal and having representation increases approval rates.

What if I cannot afford to wait for a decision?

If you have limited income and resources, you may be able to file for Supplemental Security Income (SSI) at the same time as SSDI. SSI provides emergency payments while your SSDI case is pending, though the amount is small. Ask the SSA representative when you file whether you might be may be able to access for SSI.

Can I work part-time while receiving disability benefits?

Yes, Social Security has work incentives that allow you to earn money without losing benefits. The Trial Work Period lets you work and earn any amount for nine months without affecting your benefits. After that, you enter the Extended may be able to access Period, where you can work and earn up to $1,550 per month without losing benefits. Earnings above that may reduce your payment.
