What you need to do to file for SSDI

To file for Social Security Disability Insurance (SSDI), you submit a claim to the Social Security Administration (SSA) through one of three routes: online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. The SSA will ask you to document your medical condition, work history, and earnings record. You do not need a lawyer to file, though some people hire one to represent them later in the process if their claim is denied.

The filing itself takes about 15 to 30 minutes. You will answer questions about your condition, when it started, which doctors have treated you, and what work you have done in the past 15 years. The SSA uses this information to determine whether your condition meets their definition of disability — meaning you cannot work for at least 12 months or have a condition expected to result in death.

After you file, the SSA sends your case to your state's Disability information Services (DDS) office, which reviews your medical records and makes the initial decision. This step typically takes 3 to 6 months, though it can take longer if the DDS needs more medical evidence 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; online is usually fastest.
  • You must have worked long enough and recently enough to have earned enough Social Security credits; the SSA will tell you during the filing process whether you meet this requirement.
  • The SSA will request medical records directly from your doctors, so you do not need to gather and mail them yourself, though providing a list of your doctors speeds the process.
  • The initial decision typically arrives 3 to 6 months after you file; if denied, you can request reconsideration or a hearing before an administrative law judge.
  • You receive back pay to the month you became disabled (or the month you turned 62, whichever is later), not to the month you filed.

Documents and information to have ready

Before you file, gather your Social Security number, birth certificate, and a list of all doctors and hospitals that have treated you for your condition. You will also need to know the dates you saw each provider and what conditions they treated you for. If you have recent medical test results, imaging reports, or therapy notes, having those dates and provider names handy will help you answer the SSA's questions more accurately.

The SSA will request your complete medical records from your providers, so you do not need to obtain copies yourself. However, if you know your doctors have records that are especially important to your case — such as imaging showing your condition, or detailed notes about your functional limitations — you can mention those specifically when you file. This can speed up the review process.

You should also have a record of your work history for the past 15 years, including job titles, employers, and approximate dates. The SSA has your earnings record on file, so they can verify this information, but having it ready helps you answer questions more quickly during the filing call or appointment.

Work credits and recent work requirements

To receive SSDI, you must have earned enough Social Security work credits through payroll taxes. In 2024, you earn one credit for each $1,730 of wages (this amount changes yearly). You need 40 credits total, and at least 20 of those credits must have been earned in the 10 years before you became disabled. The SSA calculates this automatically when you file — you do not need to do the math yourself.

If you have not worked recently or did not work long enough, you will not meet the work credit requirement, and the SSA will deny your claim. Self-employed people, gig workers, and people who worked for cash without paying taxes do not have credits for that work. If this applies to you, the SSA will explain during the filing process whether you have enough credits to proceed.

There is no income limit for SSDI itself, though if you earn more than a certain amount per month while working, the SSA may determine you are not disabled. In 2024, that limit is $1,550 per month (or $2,590 if you are blind). If you earn more than this, your case will likely be denied or closed.

The medical review process

After you file, the SSA sends your case to your state's Disability information Services office. That office orders your medical records from the doctors and hospitals you listed. The DDS medical consultant and disability examiner review those records to see whether your condition meets or equals one of the SSA's listed impairments, or whether your condition is severe enough that you cannot do any work.

The SSA publishes a list called the Blue Book that describes medical conditions that automatically may have access to for disability. These include conditions like stage 3 or 4 chronic kidney disease, certain cancers, severe arthritis, and advanced Parkinson's disease. If your condition matches one of these listings exactly, approval is faster. If it does not match a listing, the DDS will assess your functional capacity — what you can and cannot do physically and mentally — to decide whether you can work.

The DDS may request additional medical evidence from your doctors if the records on file are incomplete or outdated. If your doctors do not respond within 30 days, the DDS may make a decision based on what they have. This is why providing your doctor's contact information during filing is important — it helps the SSA reach them quickly.

Timeline from filing to first decision

The SSA typically makes an initial decision within 3 to 6 months of receiving your complete file. In some states, this takes longer — up to 9 months — depending on how busy the DDS office is and how complex your medical records are. Cases involving multiple conditions or conflicting medical opinions take longer than straightforward cases.

You will receive a written decision in the mail. If approved, the letter will state your monthly benefit amount and the month your benefits begin. If denied, the letter will explain the reason and tell you how to request reconsideration or appeal. You have 60 days from the date on the letter to request the next step.

While you wait for a decision, you can continue working if you are able. However, if you earn more than the monthly limit ($1,550 in 2024), it may affect your case. You should report any work and earnings to the SSA, either by phone or through your online my Social Security account.

What happens if your claim is denied

If the SSA denies your claim, you have the right to request reconsideration, which means a different DDS examiner will review your case. You can submit new medical evidence at this stage — for example, test results or doctor's notes from after your initial filing. Reconsideration decisions typically arrive 3 to 6 months after you request it.

If reconsideration is also denied, you can request a hearing before an administrative law judge (ALJ). This is a formal proceeding where you can present evidence and testimony, and your doctor or a vocational expert may testify on your behalf. Many people hire a disability lawyer at this stage, though it is not required. Hearing decisions typically arrive 4 to 12 months after you request one, depending on the judge's caseload.

If the ALJ denies your claim, you can appeal to the Appeals Council, and then to federal court. These steps are rare — most cases are approved at the hearing stage if they reach that far. A disability lawyer can explain your options after each denial.

Back pay and when benefits start

If you are approved for SSDI, you receive back pay for the months between when you became disabled and when the SSA approves your claim. However, the SSA does not pay back pay for the first five months you are disabled — this is called the waiting period. So if you became disabled in January and were approved in September, you would receive back pay for April through August (five months), not for January through August.

Your ongoing monthly benefit is based on your average lifetime earnings. The SSA calculates this using your earnings record, which is why people who worked longer or earned more typically receive higher monthly payments. In 2024, the average SSDI payment is around $1,550 per month, but payments range from a few hundred dollars to over $3,800 depending on your work history.

Your first regular monthly payment arrives the month after your approval letter is dated. If you were approved in September, your first payment arrives in October. Back pay is usually sent as a lump sum in the first or second payment.

Frequently Asked Questions

Can I file for SSDI if I am still working?

Yes, you can file while working, but if you earn more than $1,550 per month (in 2024), the SSA may determine you are not disabled and deny your claim. If you earn less than this amount, you can file and continue working while your case is reviewed. Report all work and earnings to the SSA.

Do I need a doctor's statement saying I am disabled?

No. The SSA requests your medical records directly from your doctors and makes the disability information themselves. You do not need your doctor to write a letter saying you are disabled. However, detailed medical records showing your symptoms, test results, and functional limitations help your case.

What if I do not have a regular doctor?

You can still file, but the SSA will have fewer medical records to review. If you have seen any doctors, therapists, or specialists — even once — list them. If you have not seen any medical providers, consider seeing one before filing so there is medical evidence of your condition. The SSA cannot approve a claim based only on your own description of your condition.

How much will I receive per month?

Your monthly payment depends on your lifetime earnings record. The SSA calculates this automatically and tells you the amount in your approval letter. You can estimate your payment by creating an account at ssa.gov and viewing your earnings record, though the actual amount is not final until the SSA approves your claim.

Can I work after I am approved for SSDI?

Yes. SSDI has a trial work period that allows you to work and earn any amount for nine months without losing benefits. After that, if your earnings exceed $1,550 per month, your benefits will stop. However, you can return to benefits if your earnings drop below that amount again. Report all work to the SSA.
