Where to start filing in Illinois

You file for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) through Social Security itself, not through the state of Illinois. The state does not run the disability program — Social Security does. You can file online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office.

Illinois has 42 Social Security field offices spread across the state. Finding your nearest office is useful if you prefer to file face-to-face or need help with documents, but it is not required. Many people file entirely online or by phone and never visit an office.

The online route (ssa.gov/applyfordisability) is fastest if you have your documents ready. You can save your progress and come back to it. The phone line has wait times but a representative can answer questions as you go. In-person filing at a field office takes longer but gives you a chance to ask about your specific situation.

Key Takeaways

  • Social Security, not Illinois, runs the disability program, and you file directly with them online, by phone, or at a local field office.
  • You need your Social Security number, birth certificate, proof of citizenship or legal residency, and medical records showing your condition and treatment history.
  • The online process at ssa.gov/applyfordisability is usually the fastest route if you have your documents ready.
  • Illinois has a state agency called the Disability information Services (DDS) that reviews your medical evidence, but you do not contact them directly — Social Security sends your case to them.
  • The decision process typically takes three to six months, and you will receive a written notice by mail explaining whether you were approved or denied.

Documents you need before you file

Gather these documents before you start the process, whether online or by phone. Having them ready speeds up the process and reduces the chance you will have to resubmit later.

You will need your Social Security number, birth certificate, and proof you are a U.S. citizen or have legal residency status (passport, green card, or visa). You also need proof of your medical condition — this is the most important part. Bring medical records from your doctors, hospital visits, or mental health providers that show your diagnosis, when treatment started, and what medications or therapy you receive. If you have test results (X-rays, lab work, imaging scans), include those too.

Bring proof of your work history: your most recent W-2 forms or tax returns if you are self-employed. If you have not worked in the past 15 years, you still need to list the jobs you held and when. You will also need your bank account information if you want your payments deposited directly, and the names and phone numbers of your doctors so Social Security can request your full medical file.

How the Illinois Disability information Services reviews your case

After you file, Social Security sends your case to the Disability information Services (DDS), which is the state agency that decides whether you meet the medical requirements for disability. DDS is part of the Illinois Department of Financial and Professional Regulation, but you do not contact them directly — Social Security handles all communication with you.

DDS will request your complete medical records from every doctor, hospital, and therapist you listed. They review these records to see whether your condition meets or equals one of the conditions on Social Security's list of disabling impairments. This review takes time because they have to wait for records to arrive from multiple providers.

If DDS needs more information about your condition, they may schedule you for a consultative examination (CE) with a doctor they choose. You do not pay for this exam. If DDS denies your case, you have the right to appeal, and the appeal goes back through DDS first before it can reach a judge.

Timeline: what to expect month by month

The decision process is not fast. Most cases take three to six months from the day you file to the day you receive a written decision. Some take longer if DDS is waiting for medical records or if they schedule a consultative exam.

In the first two weeks, Social Security will contact you to confirm information and may ask you to sign a form authorizing them to request your medical records. After that, you will likely hear nothing for several weeks while DDS gathers records from your providers. If DDS needs a consultative exam, they will mail you an appointment notice with the date, time, and location.

Once DDS has all the medical evidence, they write a decision. You will receive this decision by mail — not by phone or email. The letter will explain whether you were approved or denied, and if denied, it will explain why and tell you how to appeal.

What happens if you are denied

Denial is common on the first process. About 65 to 70 percent of initial applications are denied. If you receive a denial letter, you have 60 days from the date on the letter to file an appeal. Do not wait — the 60-day window is strict.

The first level of appeal is called reconsideration. You request this by contacting Social Security in writing or by phone. A different examiner at DDS will review your case from the start, and you can submit new medical evidence. This takes another two to three months.

If reconsideration is also denied, the next step is a hearing before an Administrative Law Judge (ALJ). You can represent yourself or hire a lawyer. Many people find that having a representative helps at this stage because the judge will ask detailed questions about your medical condition and your ability to work. The hearing wait time varies but is often six months to a year.

Illinois resources outside the Social Security process

While you wait for a decision, you may need income support or health coverage. Illinois has programs that can help while your case is pending.

Supplemental Security Income (SSI) is different from SSDI. If you have very little income and assets, you may be found disabled under SSI rules even if you do not have enough work history for SSDI. You can file for both at the same time. SSI includes a small monthly payment plus Medicaid coverage in Illinois.

If you are waiting for a decision and have no income, you can explore for SNAP (food information) and LIHEAP (utility information) through the Illinois Department of Human Services. You can also explore for Medicaid while your disability case is pending — approval for Medicaid does not require the same medical standard as disability approval.

The Illinois Assistive Technology Program offers free equipment loans and training if your disability affects your ability to work or live independently. Contact them at 217-522-7985 or visit iltech.org.

Frequently Asked Questions

Can I file for disability in Illinois if I have not worked much?

You may still be able to file under SSI, which does not require work history. SSI is for people with very low income and assets. SSDI requires you to have worked and paid Social Security taxes, but the amount of work history needed depends on your age. A Social Security representative can tell you whether you may have access to for either program.

Do I need a lawyer to file for disability in Illinois?

No, you can file on your own. Many people do. A lawyer or representative is most useful if your case is denied and you are preparing for a hearing before a judge. If you hire a representative, they can only charge you if you win, and the fee is capped at 25 percent of your back pay, up to $7,200.

What if I move out of Illinois while my case is pending?

Your case stays with Social Security and DDS. You do not have to restart it. Tell Social Security your new address so they can mail your decision to the right place. If you move to another state, the appeal process works the same way.

Can I work while I wait for a disability decision?

Yes. Working does not hurt your case, but if you earn over a certain amount ($1,550 per month in 2024, though this changes yearly), it may affect SSI payments if you are found disabled. SSDI has a higher earnings limit. Report any work to Social Security so they can calculate your benefits correctly.

How do I check the status of my disability process in Illinois?

Call Social Security at 1-800-772-1213 with your Social Security number and the date you filed. They can tell you whether your case is still being reviewed or whether a decision has been mailed. You can also create an account at ssa.gov/myaccount to check your process status online.
