What happens when you file for SSDI

When you file for SSDI, you are asking the Social Security Administration (SSA) to review your medical records and work history to decide whether your condition prevents you from working. The SSA does not make this decision quickly — most cases take three to six months to receive an initial decision, though some take longer. You will need to provide detailed information about your condition, the doctors who treat you, and your work history since age 21.

Filing does not cost money. You do not need a lawyer to file, though some people hire one to help with the process. If you are approved, you will receive monthly payments, but these do not start until five months after your condition began — this waiting period is built into how SSDI works.

Key Takeaways

  • 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 from every doctor who has treated you for your condition, so gather those names and dates before you start.
  • You must have worked and paid Social Security taxes for a certain number of years — usually at least five of the last ten years — to be found disabled.
  • Most initial decisions take three to six months, and many people are denied the first time and must request reconsideration or a hearing.
  • If you are approved, your first payment arrives six months after your condition began, not six months after you filed.

Where and how to file

You have three ways to file for SSDI. The fastest is usually online at ssa.gov — you can start an process there and return to it later if you need to gather information. You can also call the SSA at 1-800-772-1213 (TTY 1-800-325-0778) and complete the process over the phone with a representative. Hours are Monday through Friday, 7 a.m. to 7 p.m. your local time. The phone line is often busy, especially early in the week.

A third option is to walk into your local Social Security office and file in person. You can find the address at ssa.gov or by calling the number above. Filing in person takes longer that day but may be easier if you have questions or need help understanding what information to provide.

Whichever method you choose, you will need the same documents and information. Starting online and finishing by phone is common — the SSA will save your progress.

Documents and information you will need

Before you file, gather these items: your Social Security card, birth certificate, proof of citizenship or legal residency (passport, green card, or state ID), and your most recent tax return or W-2 form. You will also need the names, addresses, and phone numbers of every doctor, hospital, and mental health provider who has treated you for your condition, along with the dates you saw them.

The SSA will contact these providers directly to request your medical records, so accuracy matters. If you have seen many doctors, write down the complete list — do not leave anyone out, even if you saw them only once or years ago. The SSA uses all available records to make its decision.

You should also have a list of all jobs you have held since age 21, including the years you worked and the names of your employers. If you are self-employed or own a business, bring records showing your income for the past two years.

What the SSA will ask about your condition

The SSA will ask detailed questions about how your condition affects your ability to work. They want to know what tasks you cannot do, how long you can sit or stand, whether you can lift things, and how your condition changes day to day. They will also ask about your medications, side effects, and any treatment you are receiving.

Be specific and honest. Saying "I cannot work" is not enough — the SSA needs to understand exactly why. For example, instead of "I have back pain," explain: "I can sit for 20 minutes before pain forces me to stand. I cannot lift more than 10 pounds. On bad days, I cannot get out of bed." The more detail you provide, the clearer your case becomes.

The SSA will also ask about your daily activities: can you cook, clean, shop, or drive? Can you manage your own medications and appointments? These questions help the SSA understand whether your condition truly prevents work or whether you can still do some activities.

Work history and Social Security credits

To receive SSDI, you must have earned enough Social Security credits through work. Most people need 40 credits total, with at least 20 earned in the ten years before they became disabled. You earn one credit for every $1,730 of wages (in 2024 — this amount changes yearly), up to four credits per year. This means you need roughly five years of full-time work in the past ten years.

If you have not worked enough, you may not be found disabled under SSDI rules. However, you might be found disabled under Supplemental Security Income (SSI) instead, which has different rules and does not require work history. The SSA will check both programs when you file.

The SSA already has your work history on file from your tax returns and W-2 forms, so you do not need to prove this yourself. However, if you worked under a different name or Social Security number, tell the SSA so they can find those records.

What happens after you file

After you file, the SSA sends your case to your state's Disability information Services (DDS) office. This office reviews your medical records and decides whether your condition meets the SSA's definition of disability. The DDS is separate from Social Security — it is a state agency that works with the SSA.

The DDS will contact your doctors and may ask you to see a doctor they choose for an examination. This examination is free and does not mean they think you are lying — it is standard procedure. You should attend this appointment; missing it can result in a denial.

Most decisions arrive within three to six months. The SSA will mail you a letter explaining whether you were approved or denied. If you are approved, the letter will tell you when your payments begin. If you are denied, the letter will explain why and tell you how to request reconsideration.

If you are denied

Most people are denied on their first process. This does not mean you cannot receive SSDI — it means the SSA needs more information or a different approach. You have the right to request reconsideration, which means a different examiner reviews your case. You must request reconsideration within 60 days of the denial letter.

If reconsideration is also denied, you can request a hearing before an Administrative Law Judge (ALJ). This is a formal hearing where you can present your case in person or by phone, bring witnesses, and answer questions. Many people are approved at the hearing stage. You must request a hearing within 60 days of the reconsideration denial.

At any stage, you can hire a lawyer or representative to help you. They are paid only if you win, and their fee is limited by law — usually 25% of your back pay, up to $7,200. Many representatives work for disability advocacy organizations and charge nothing.

Frequently Asked Questions

Can I work while my SSDI case is being decided?

Yes. Working does not hurt your case, but if you earn more than $1,550 per month (in 2024), the SSA may question whether you are truly unable to work. Keep records of what you earn and what you do at work — this information helps your case if the SSA asks.

What if I do not have medical records from my doctors?

Tell the SSA which doctors you have seen and when. The SSA will contact them and request records. If a doctor no longer has records or has retired, the SSA will note this. Gaps in medical records can make approval harder, so if you are not currently seeing a doctor, consider scheduling an appointment before you file.

How much will I receive if I am approved?

SSDI payments are based on your lifetime earnings record, not on how disabled you are. The average payment in 2024 is around $1,550 per month, but yours could be higher or lower. The SSA will tell you the exact amount in your approval letter.

Can I file for SSDI if I am still working full-time?

Yes, you can file while working. However, if you are earning substantial income, the SSA may decide you are not disabled. The SSA looks at whether you can do any work, not just your current job. If your condition prevents you from working but you are pushing through it, explain this to the SSA.

What if my condition gets worse after I file?

Send new medical records to the SSA when ready. Write a letter explaining what has changed and include recent test results, doctor's notes, or hospital records. This new information can strengthen your case, especially if you are in the reconsideration or hearing stage.
