The basic steps to file for SSDI

You can file for Social Security Disability Insurance (SSDI) in three ways: online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. The online method is usually fastest—you can start your process whenever you want and save your progress. By phone, a representative will walk you through the questions. In person, staff can answer questions as you fill out the form together.

No matter which method you choose, you will need the same basic information: your Social Security number, birth certificate, proof of citizenship or legal residency, and medical records showing your condition and treatment. You will also need to list your work history for the past 15 years, including the names and addresses of employers.

After you submit your process, Social Security sends it to your state's Disability information Services (DDS) office. That office reviews your medical evidence and decides whether your condition meets Social Security's definition of disability. This process typically takes 3 to 6 months, though it can take longer if Social Security needs more medical records from your doctors.

Key Takeaways

  • You can file online at ssa.gov, by phone at 1-800-772-1213, or at your local Social Security office, and each method takes roughly the same amount of time to process.
  • You will need your Social Security number, birth certificate, proof of citizenship, medical records, and a 15-year work history before you start.
  • Social Security sends your process to your state's Disability information Services office, which makes the decision on your case.
  • The decision process usually takes 3 to 6 months, and you will receive a written notice in the mail telling you whether you were approved or denied.
  • If you are denied, you have the right to appeal, and most people who appeal with new medical evidence or a lawyer have better outcomes.

What documents you need before you start

Gather these documents before you begin your process. You will need your original birth certificate or a certified copy, a document proving U.S. citizenship or legal residency (passport, naturalization papers, or green card), and your Social Security card or a record of your number. If you do not have these, Social Security can sometimes help you get them, but it slows down your process.

Medical records are the most important part of your file. Bring records from every doctor, hospital, or mental health provider who has treated you for your condition in the past few years. Include test results, imaging reports, therapy notes, and medication lists. If your doctors have written statements about how your condition affects your ability to work, include those too. Social Security will request records directly from your providers, but having copies ready speeds things up.

You will also need a complete work history. Write down the names and addresses of every employer you have worked for in the past 15 years, the dates you worked there, and the type of work you did. If you are self-employed, gather tax returns and records of your income. If you cannot remember exact dates or addresses, do your best—Social Security can fill in gaps using Social Security records.

Filing online versus by phone versus in person

Online filing at ssa.gov/applyfordisability is available 24 hours a day. You create an account, answer questions about your medical condition and work history, and upload documents. You can save your progress and come back later. After you submit, you receive a confirmation number. This method works well if you prefer to take your time and do not have questions that need when ready answers.

Filing by phone at 1-800-772-1213 (TTY 1-800-325-0778) connects you to a Social Security representative who asks the same questions as the online form. The call usually takes 15 to 30 minutes. You can ask questions as you go, and the representative can clarify what information Social Security needs. Wait times vary by time of day and season; calling early in the morning or mid-week is usually faster.

Filing in person at your local Social Security office gives you face-to-face help. A staff member walks through the process with you, answers questions, and can sometimes scan documents on the spot. You can find your nearest office at ssa.gov/locator. In-person appointments are often booked weeks in advance, so call ahead or use the online appointment scheduler.

What happens after you submit your process

Once Social Security receives your process, they send it to your state's Disability information Services office. That office is separate from Social Security—it is run by your state but follows federal rules. A team there (usually a doctor and a disability examiner) reviews your medical records and decides whether your condition prevents you from working.

Social Security will likely contact your doctors to request more records. This can take weeks. If records are missing or unclear, Social Security may ask you to see a doctor for a consultative exam at no cost to you. You do not have to pay for this exam—Social Security pays the doctor.

You will receive a written decision in the mail. The letter will say whether you were approved, denied, or approved for a different program (like Supplemental Security Income, or SSI, if you have low income). If you are approved, the letter tells you when your benefits start and how much you will receive each month.

Understanding the medical standard for disability

Social Security has a specific definition of disability: your condition must prevent you from doing any substantial work for at least 12 months or result in death. This is stricter than many people expect. Having a diagnosis is not enough—Social Security looks at what your condition actually prevents you from doing.

Social Security uses a five-step process to decide. First, they check whether you are working and earning more than $1,550 per month (this amount changes each year). If you are, they usually deny the case. Second, they decide whether your condition is severe enough to affect your ability to work. Third, they check whether your condition is on Social Security's list of conditions that automatically may have access to. Fourth, they assess whether you can do the work you did before. Fifth, they decide whether you can do any other work that exists in the economy.

Most denials happen at step five—Social Security decides that even though you cannot do your old job, you could do lighter work. This is where medical evidence matters most. Detailed records from your doctors about your limitations, pain, fatigue, concentration problems, or other symptoms help Social Security understand why you cannot work at all.

Timeline and what to expect while you wait

The decision process usually takes 3 to 6 months from the date you submit your process. Some cases take longer if Social Security needs to request records from multiple providers or if your case is complex. A few cases are decided faster—usually within 1 to 2 months—if your medical evidence is clear and complete.

You will not hear anything for the first few weeks. Social Security is gathering records and sending your file to the state office. Around 4 to 8 weeks after you file, you may receive a letter asking for more information or requesting that you see a doctor for an exam. If you receive such a letter, respond quickly—delays in sending information can slow your decision.

Once the state office makes a decision, they mail you a letter. The letter explains the decision and, if you were denied, tells you how to appeal. Keep this letter—you will need it if you decide to appeal or if you need to prove you filed on a certain date.

What to do if you are denied

If Social Security denies your case, you have four levels of appeal. The first level is called "reconsideration"—a different examiner reviews your case, usually with new medical evidence. You have 60 days from the date on your denial letter to request reconsideration. Many people gather new medical records from their doctors during this time, which improves their chances.

If reconsideration is denied, you can request a hearing before an Administrative Law Judge (ALJ). This is a formal hearing where you can present evidence and testify. You can bring a lawyer or non-lawyer representative. Many people win at the hearing level, especially if they have a representative and new medical evidence. The wait for a hearing can be 6 months to over a year depending on your area.

If the ALJ denies your case, you can appeal to the Appeals Council, and then to federal court. Most people who win on appeal do so because they have gathered more medical evidence showing their condition is worse than the initial file showed, or because they have hired a lawyer who knows how to present the evidence effectively.

Frequently Asked Questions

Can I file for SSDI if I am still working?

Yes, you can file while working. However, if you earn more than $1,550 per month (in 2024), Social Security will likely deny your case based on work activity alone. If you earn less than that, you can file, and Social Security will review your medical condition. Many people file when they are about to stop working or have already reduced their hours.

Do I need a lawyer to file for SSDI?

No, you do not need a lawyer to file your initial process. Many people file on their own. However, if your case is denied and you appeal, a lawyer or representative who knows disability law can significantly improve your chances. Lawyers are paid only if you win, and they take a percentage of your back pay (usually up to 25%).

What if I do not have all my medical records?

Start your process anyway. Social Security will request records from your doctors and providers. If records are missing or incomplete, Social Security may order a consultative exam. Waiting to file until you have every record can delay your process by months. It is better to file now and let Social Security help gather what is needed.

How much will I receive if I am approved?

Your monthly benefit amount depends on your work history and earnings record. The average SSDI payment in 2024 is around $1,550 per month, but payments range from a few hundred dollars to over $3,800 depending on your situation. Social Security will tell you the exact amount in your approval letter.

Can I work while receiving SSDI?

Yes, but with limits. You can earn up to $1,550 per month (in 2024) without losing benefits. Above that amount, Social Security may reduce or stop your benefits. There is also a nine-month trial work period where you can earn any amount without losing benefits. After that, the $1,550 limit applies for 36 months. Ask Social Security about the rules before you start working.
