The Basic Steps to File for SSDI

To file for Social Security Disability Insurance, you submit a claim to the Social Security Administration (SSA) describing your medical condition and work history. You can file 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 how your condition prevents you from working. 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 definition of disability under Social Security rules.

The process typically takes three to six months, though some cases take longer. You will receive a written decision in the mail. If you are denied, you have the right to appeal within 60 days of the denial letter.

Key Takeaways

  • You can file online, by phone, or in person; online filing at ssa.gov is usually fastest and requires no appointment.
  • The SSA will need your medical records, so gathering these before you file speeds up the process.
  • Your state's Disability information Services office, not the SSA, makes the final decision on your claim.
  • The decision process takes three to six months on average, and you can appeal if you are denied.
  • You must have worked long enough and recently enough to have earned enough Social Security credits for SSDI; the SSA will tell you if you meet this requirement.

What Documents You Will Need

Before you file, gather your Social Security card, birth certificate, and proof of citizenship or legal residency (passport, driver's license, or state ID). You will also need a list of all doctors, hospitals, and mental health providers who have treated you for your condition, along with the dates of those visits.

Medical records are the most important part of your claim. The SSA will request these directly from your providers, but having them ready yourself speeds things up. Include records from the past 12 months if possible. If you have test results, imaging reports, or specialist evaluations, those carry more weight than general office notes. You should also have a list of all medications you take and any side effects they cause.

Bring your work history: the names and dates of your last jobs, what you did, and how much you earned. The SSA can look this up, but having it written down helps. If you are self-employed, bring tax returns from the past two years.

Filing Online versus Phone versus In Person

Filing online at ssa.gov/applyfordisability is the fastest route. You create an account, fill out the form, and submit it when ready. You do not need an appointment, and you can save your progress and come back later. The SSA will contact you by phone or mail if they need more information. Most people who file online hear back within a few weeks about whether their process was received correctly.

Filing by phone at 1-800-772-1213 takes about 30 minutes. You speak to an SSA representative who asks the same questions as the online form. This works well if you have questions while filling it out or if you are not comfortable using a computer. Wait times vary by time of day; calling early morning on a weekday is usually faster.

Filing in person at your local Social Security office means you can bring documents with you and have someone review them on the spot. Find your office at ssa.gov/locator. You may need to wait, and you should call ahead to ask whether you need an appointment. In-person filing is useful if you have complex work history or medical situations and want to explain them directly.

What Happens After You File

After you submit your claim, the SSA sends it to your state's Disability information Services office within one to two weeks. The DDS office is staffed by disability examiners and doctors who review your medical records and work history. They do not meet with you in person; they make their decision based on paperwork. If they need more information, they will request it from your doctors or ask you to have a medical exam.

The DDS office will contact you by mail if they need additional records or want you to see a doctor for an examination. Respond to these requests quickly — delays in sending records or scheduling exams can slow your case. If you cannot afford a medical exam, the SSA will pay for it.

Once the DDS office makes a decision, they send it to the SSA, which mails you a formal notice. This letter explains whether you were approved or denied and why. If you were approved, it tells you when your benefits start. If you were denied, it explains your right to appeal and the important date to do so.

Understanding the Definition of Disability for SSDI

Social Security has a specific definition of disability that is stricter than many people expect. You must have a medical condition that prevents you from doing any substantial work for at least 12 months or that is expected to result in death. "Substantial work" means earning more than a certain amount per month; in 2024, that amount is $1,550 for non-blind individuals and $2,590 for blind individuals, though these amounts change yearly.

Your condition must be severe enough that you cannot do the work you did before and cannot adjust to other work that exists in the national economy. The SSA looks at your age, education, and work skills. A 55-year-old with a high school diploma and a back injury has a better chance of approval than a 35-year-old with the same injury, because the SSA assumes it is harder for older workers to retrain.

The SSA uses a five-step process to decide: (1) Are you working and earning substantial income? If yes, you are denied. (2) Is your condition severe? If no, you are denied. (3) Does your condition match a condition on the SSA's list of severe impairments? If yes, you are likely approved. (4) Can you do your past work? If yes, you are denied. (5) Can you do any other work? If no, you are approved. Most denials happen at step 5.

What to Do If You Are Denied

If the SSA denies your claim, you have 60 days from the date on the denial letter to file an appeal. Do not wait — if you miss this important date, you must file a new claim and start over. The first appeal is called a reconsideration, and it goes to a different examiner at the DDS office who reviews your entire case from scratch.

For a reconsideration, submit any new medical records you have gathered since your first claim. If your condition has worsened or you have new test results, include those. A reconsideration takes another three to six months. If you are denied again, you can request a hearing before an Administrative Law Judge (ALJ), which is a federal judge who specializes in Social Security cases. Many people win at the hearing stage, especially if they have a lawyer or representative.

You do not need a lawyer to appeal, but having one increases your chances. A lawyer who handles Social Security cases can review your medical records, identify weaknesses in your case, and prepare you for a hearing. Lawyers are paid only if you win, and they take a percentage of your back pay (the money owed from when you first filed).

Work and Earnings While Your Claim Is Pending

You can work while your SSDI claim is being decided. However, if you earn more than the substantial gainful activity (SGA) limit — $1,550 per month in 2024 for non-blind individuals — the SSA may deny your claim on the grounds that you are capable of substantial work. Keep your earnings below this amount if possible while your case is pending.

If you are already receiving SSDI and return to work, different rules explore. You have a nine-month trial work period during which you can earn any amount without losing benefits. After that, benefits stop if you earn more than the SGA limit. However, you can use work incentives like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) to deduct certain costs from your earnings and keep benefits longer. These are complex rules, and it is worth talking to a benefits planner before you start working.

Frequently Asked Questions

Can I file for SSDI if I have never worked?

No. SSDI is based on your work history and the Social Security taxes you have paid. You must have earned enough Social Security credits through work to may have access to. If you have never worked, you may be able to file for Supplemental Security Income (SSI) instead, which is a needs-based program. The SSA will tell you during your process whether you may have access to for either program.

How long does it take to get a decision?

Initial claims usually take three to six months. Reconsiderations take another three to six months. Hearings before an Administrative Law Judge can take one to two years, depending on how busy the judge's office is. Some cases move faster; others take longer. You can check the status of your claim online at ssa.gov/myaccount or by calling 1-800-772-1213.

What if my doctor says I cannot work but the SSA denies me?

The SSA does not automatically approve claims based on a doctor's statement. The SSA uses its own definition of disability and looks at whether you can do any work in the national economy, not just your past job. If your doctor's records support your claim, make sure they are in your file. If the SSA denies you, you can appeal and request a hearing, where you can present your doctor's testimony or written statement.

Do I need a lawyer to file?

You do not need a lawyer to file your initial claim or reconsideration. Many people file on their own and are approved. However, if you are denied twice and go to a hearing, having a lawyer or representative increases your chances of winning. Lawyers work on contingency, meaning they are paid only if you win, and their fee comes from your back pay.

Can I file for SSDI while I am still working?

Yes, you can file while working. However, if you earn more than $1,550 per month (in 2024), the SSA may deny your claim because you are performing substantial work. If your earnings are below this amount, filing while working is fine. Once you are approved, different rules explore about how much you can earn.
