The basic steps to claim SSDI
To claim Social Security Disability Insurance (SSDI), you start by contacting Social Security directly — either by phone, in person, or online. You will need to provide medical evidence that you have a condition that prevents you from working, along with work history and personal information. Social Security then reviews your case, which typically takes three to five months, though some cases take longer. If approved, your benefits begin the month after you meet a five-month waiting period from when your disability started.
The process is free. Social Security does not charge you to file, and you do not need a lawyer to start. However, many people do hire a representative later if their case is denied and they appeal — and representatives can only charge you if you win.
The three ways to file are by phone (1-800-772-1213), online at ssa.gov, or by visiting your local Social Security office. Filing online is often fastest because you can do it on your own schedule and Social Security will contact you if they need more information.
Key Takeaways
- You file directly with Social Security, not with your state or your doctor — by phone, online, or at a local office.
- You must provide medical records showing your condition and how it stops you from working, plus documentation of your work history.
- The review process takes three to five months on average, and you should expect Social Security to request additional medical information during that time.
- Even if you are denied, you have the right to appeal, and many people win on appeal or at a hearing before an administrative law judge.
What documents and information you need to gather
Before you file, collect your Social Security card (or the number), birth certificate, and proof of citizenship or legal residency. You will also need your most recent tax return or W-2 forms to show your work history, and a list of all jobs you have held in the past 15 years.
The most important part of your claim is medical evidence. Gather records from every doctor, hospital, mental health provider, or specialist who has treated your condition. This includes test results, imaging reports, therapy notes, medication lists, and any diagnoses. If you have not seen a doctor recently, Social Security may refer you to one at no cost to you — but having your own records speeds the process considerably.
Write down the dates you stopped working or reduced your hours, and the reason. Social Security needs to know when your disability began, because benefits do not go back further than that date.
How to file online, by phone, or in person
Filing online at ssa.gov is usually the fastest route. Go to the Social Security website, find the "Disability" section, and look for "explore for Disability Benefits." You can save your progress and come back to it. The form asks about your medical condition, work history, and personal details. You upload or describe your medical records as part of the online form.
Filing by phone means calling 1-800-772-1213 (TTY 1-800-325-0778 for deaf and hard of hearing). A representative will walk you through the questions and take your information over the phone. This takes about 30 to 45 minutes. You will still need to send in your medical records and other documents afterward.
Filing in person at your local Social Security office means making an appointment (you can book one online or by phone). A representative will help you fill out the process and can answer questions on the spot. Bring all your documents with you. This is the slowest route because you have to travel and wait, but some people prefer it if they have questions or language barriers.
What happens after you file
After you submit your process, Social Security sends you a receipt notice with a case number. Keep this number — you will use it to check on your case status. You can check online at ssa.gov using your personal account, or call 1-800-772-1213 and give them your number.
Social Security will contact you if they need more information. This might be a phone call asking you to clarify something, or a request to have your doctor send additional records. Respond quickly when they ask for something — delays in sending information can slow down your case.
During the review, a Disability information Services (DDS) office in your state evaluates your medical evidence. They are not Social Security staff — they are a separate state agency that makes the medical decision. If your case is straightforward and you have strong medical evidence, you may hear back in three months. Complex cases or cases with missing records can take six months or longer.
Understanding the decision letter
Social Security will send you a decision letter by mail. It will say either "approved," "denied," or "approved for a different reason than you expected" (for example, approved for a different condition than the one you listed).
If you are approved, the letter tells you when your benefits start, how much you will receive each month, and when the first payment arrives. Your first check usually comes within one to two months after approval.
If you are denied, the letter explains why — for example, "your condition does not meet our criteria" or "you can still work." The letter also tells you that you have the right to appeal. You have 60 days from the date on the letter to file an appeal, though you can ask for more time if you need it.
What to do if your claim is denied
A denial does not mean you cannot receive SSDI. You have four levels of appeal: reconsideration, hearing before an administrative law judge, Appeals Council review, and federal court. Most people who appeal win at one of these stages.
For reconsideration, you file a new request and Social Security sends your case to a different DDS office. This is free and takes two to four months. Many people skip this step and go straight to requesting a hearing, which is faster and gives you a chance to speak to a judge in person or by video.
At a hearing, you can bring witnesses (like a doctor or family member who knows your condition) and explain your case to an administrative law judge. The judge is not a Social Security employee — they work for the Office of Disability Adjudication and Review. Hearings often result in approval, especially if you have strong medical evidence or a representative helping you.
You do not need a lawyer to appeal, but many people hire one at this stage. A representative can charge you only if you win, and only up to 25 percent of your back pay (the money owed from when you became disabled to when you were approved).
How long the whole process takes
Initial review takes three to five months on average. If you are approved, you receive your first payment within one to two months after that. If you are denied and appeal, reconsideration takes two to four months, and a hearing request can take six months to two years depending on how busy your local hearing office is.
During the entire process — from filing to approval — you do not receive any money. This is why many people explore for Supplemental Security Income (SSI) at the same time if they have low income and few resources. SSI can provide temporary payments while you wait for SSDI to be decided.
Some people also look into expedited reinstatement if they previously received SSDI, stopped working, and then had to stop working again within five years. This faster track can get you back on benefits in weeks instead of months.
Frequently Asked Questions
Can I work while my SSDI claim is being reviewed?
Yes. Working does not disqualify you from SSDI. However, if you earn more than $1,550 per month (in 2024), Social Security may decide you can work and deny your claim. The amount changes each year. Keep records of your earnings and tell Social Security about any work you do.
Do I need a lawyer to file for SSDI?
No. You can file on your own and many people do. A lawyer or representative is most useful if your claim is denied and you are appealing. They cannot help you get approved faster, but they can improve your chances at a hearing and only charge you if you win.
What if I do not have recent medical records?
Tell Social Security when you file. They can refer you to a doctor for a free examination, though this can add time to your case. If you have not seen a doctor because of cost, look for free or low-cost clinics in your area and get evaluated before you file — your own records are usually stronger than a Social Security-ordered exam.
Can I file for SSDI if I am still working?
Yes, but Social Security will look closely at how much you earn. If you work full-time and earn a substantial income, they are likely to deny your claim because they will say you can work. Part-time work or work that pays very little does not automatically disqualify you, but you must report all earnings.
What happens if I am approved but disagree with the amount I receive?
The amount is based on your work history and earnings record — Social Security calculates it automatically and you cannot change it. If you believe your earnings record is wrong, you can request a correction by contacting Social Security with proof of your actual earnings (W-2s or tax returns).
