The basic path to disability in Illinois
To get disability benefits in Illinois, you file with Social Security, not with the state. The Social Security Administration (SSA) runs the two main disability programs: Social Security Disability Insurance (SSDI), which is based on your work history, and Supplemental Security Income (SSI), which is based on financial need. Illinois has no separate state disability program that replaces these federal ones, though the state does administer Medicaid for people approved through SSI.
You start by contacting Social Security directly. You can file online at ssa.gov, call 1-800-772-1213 (TTY 1-800-325-0778), or visit a local Social Security office in person. The office nearest you is listed on the SSA website by zip code. Filing online takes about 15 minutes and you can save your progress and come back to it.
After you file, Social Security sends your case to the Disability information Services (DDS) office in Illinois. This is the state agency that actually reviews medical evidence and decides whether you meet Social Security's definition of disability. You do not interact with DDS directly—Social Security handles all communication with you—but understanding that DDS exists helps explain why the process takes time.
Key Takeaways
- You file for disability with Social Security (not Illinois), either online at ssa.gov, by phone at 1-800-772-1213, or at your local Social Security office.
- SSDI requires a work history and is based on your own earnings record; SSI requires low income and assets and is available to anyone who meets the financial limits.
- The Illinois Disability information Services office reviews your medical records and decides your case, a process that typically takes three to five months.
- You will need medical records from your doctors, a list of your medications, work history, and school records if you are under 22 explore for SSI.
SSDI versus SSI: which program you might use
The two programs have different rules about who can receive them. SSDI is for people who have worked and paid Social Security taxes. You need a certain number of work credits—usually 40 total, with 20 earned in the last 10 years—though the exact requirement depends on your age. If you are under 31, you may need fewer credits. SSDI does not care how much money you have in the bank or what your income is now; it only looks at your work history.
SSI is for people with low income and limited assets, regardless of work history. You can have no more than $2,000 in countable resources (as of 2024; this amount changes yearly). SSI is available to anyone—including people who never worked, people under 18, and people over 65. If you are under 22 and still in school, you may be able to have more resources and still receive SSI.
Some people are approved for both programs at the same time. If you have a work history but also have very low income, Social Security will evaluate you for both and pay whichever gives you more money. If you are unsure which program fits your situation, Social Security staff can help you figure it out during your initial call or visit.
What medical evidence you need to gather
Social Security's decision rests almost entirely on medical evidence. Before you file, gather records from every doctor, mental health provider, hospital, or clinic that has treated you for your condition. This includes primary care doctors, specialists, therapists, and emergency room visits. You do not need to submit these records when you file—Social Security will request them from your providers—but having a list of names, addresses, and dates of treatment ready speeds up the process.
Write down all medications you currently take, including the dose and how often you take them. Include over-the-counter medications and supplements. Also list any surgeries, hospitalizations, or major medical events and the approximate dates. If you have test results—imaging, lab work, EKGs—note those too, though Social Security will request the official records from your doctors.
If you are explore for SSI and you are under 22, gather your school records and any evaluations from teachers or school counselors about your functioning in the classroom. If you have a work history, write down the jobs you have held in the past 15 years, including job titles, what you did, how long you worked there, and why you left. This helps Social Security understand what kind of work you could potentially do.
The timeline from filing to decision
After you file, Social Security sends your case to the Illinois DDS office within a few days. DDS then requests medical records from your doctors and reviews everything you submitted. This stage typically takes two to three months. You may receive a letter asking you to go to a consultative exam—a medical appointment paid for by Social Security with a doctor they choose—if your records do not contain enough recent information about your condition.
Once DDS has all the medical evidence, a disability examiner and a medical or psychological consultant review your case and make a decision. The whole process from filing to an initial decision usually takes three to five months, though some cases take longer if records are hard to obtain or if you need a consultative exam. You will receive a written decision in the mail explaining whether you were approved or denied.
If you are denied, you have the right to appeal. You can request reconsideration (a second review by a different examiner), and if that is also denied, you can request a hearing before an Administrative Law Judge. Each appeal stage has its own timeline—reconsideration takes about three to four months, and a hearing can take six months to over a year depending on the judge's schedule. Many people are approved at the hearing stage even if they were denied initially.
What happens after you are approved
If you are approved for SSDI, your benefits begin the month after you have been disabled for five full months. This is called the waiting period. Your first payment arrives the following month. The amount you receive is based on your earnings record—the higher your average earnings during your working years, the higher your benefit. In 2024, the average SSDI payment is around $1,550 per month, but this varies widely.
If you are approved for SSI, your benefits can begin the month you file, with no waiting period. SSI payments are lower than SSDI—the federal maximum is $943 per month in 2024—but you may also become may be able to access for Medicaid through Illinois. Illinois Medicaid covers medical care, prescriptions, and mental health services at no cost to you.
Once you receive benefits, you must report certain changes to Social Security: if you start working, if your income changes, if you move, or if your medical condition improves significantly. Failing to report changes can result in overpayments that you may have to repay. Social Security sends you a form each year asking you to confirm your information; answer it promptly and honestly.
Working while on disability
You can work while receiving SSDI or SSI, but there are limits and rules. SSDI has a trial work period that lets you test your ability to work for nine months without losing benefits. After the trial work period ends, you enter the extended may be able to access period, where you keep benefits for three more years as long as your earnings stay below a certain amount. In 2024, that amount is $1,550 per month for SSDI and $1,000 per month for SSI, but these figures change yearly.
If you earn more than the limit, your benefits reduce or stop. However, you can use work incentives to keep more of your earnings. The Plan to Achieve Self-Support (PASS) lets you set aside income and resources for a work goal without losing SSI. Impairment Related Work Expenses (IRWE) lets you deduct costs related to your disability—like transportation to a job, medication, or medical equipment—from your earnings before Social Security counts them.
Talk to Social Security about work incentives before you start working. They can explain how your specific situation would be affected and help you understand what you need to report. Many people benefit from working with a benefits planning information service, which Illinois offers through vocational rehabilitation agencies and some nonprofits.
Illinois-specific resources and support
While Social Security runs the disability programs, Illinois offers services that can help you through the process. The Illinois Department of Human Services administers Medicaid for SSI recipients and can answer questions about health coverage. The Illinois Vocational Rehabilitation Agency helps people with disabilities prepare for work and can provide job training, assistive technology, and other supports.
If you need help understanding the process or filling out forms, contact your local Area Agency on Aging and Disability (AAAD). These agencies, funded by the state, offer free information and referral services. You can find your local AAAD on the Illinois Department on Aging website. Some nonprofits in Illinois also offer free benefits counseling and help with appeals.
If you are denied and want to appeal, you can represent yourself or hire a lawyer. Many disability lawyers work on contingency, meaning they take a percentage of your back pay (usually 25 percent, capped at $6,000) only if you win. You can also use a non-lawyer representative, such as someone from a disability advocacy organization, though they charge lower fees or none at all.
Frequently Asked Questions
Can I file for disability in Illinois if I have not worked much?
If you have not worked, you cannot use SSDI because it requires a work history. You can file for SSI instead, which has no work requirement—only income and asset limits. SSI is available to anyone under 65 with a disability, regardless of whether they ever worked.
How do I know if my condition meets Social Security's definition of disability?
Social Security's definition is strict: your condition must prevent you from doing any substantial work for at least 12 months or result in death. You do not have to be unable to do your old job; you have to be unable to do any job that exists in the economy. Social Security compares your condition to a list of medical conditions (called the Blue Book) but will also consider your age, education, and work history.
What if I disagree with the decision Social Security sends me?
You have 60 days from the date on the decision letter to appeal. You can request reconsideration (a new review), and if that is denied, you can request a hearing before a judge. Many people are approved at the hearing stage. You do not need a lawyer to appeal, but having one can improve your chances.
Do I have to use a doctor Social Security chooses for the consultative exam?
Yes, if Social Security requests a consultative exam, you must attend the appointment with the doctor they select. The exam is free to you. If you have a legitimate reason you cannot attend (such as being hospitalized), contact Social Security to reschedule. Missing the exam without contacting Social Security can result in a denial.
Will I lose my benefits if I move out of Illinois?
No. SSDI and SSI are federal programs, so your benefits continue if you move to another state. However, if you receive SSI, your Medicaid coverage may change because each state runs its own Medicaid program. Contact Illinois Medicaid before you move to understand how your coverage will transfer or change.
