Filing for Disability in Illinois: Social Security and SSI

The State of Illinois adds money to the federal SSI disability payment; the amount depends on the recipient's maintenance costs.

How old are you?

While Social Security disability (SSDI) and Supplemental Security Income (SSI) are federal benefit programs that provide cash payments to those who are unable to work, there is some specific information that you should know if you intend to file for disability in Illinois.

How to File for Disability in Illinois

There are a few different ways to file for Social Security disability benefits in Illinois. You can:

  • visit your local Social Security Administration (SSA) office. The SSA's office locator can help you find the location nearest to you.
  • telephone the SSA at (800)772-1213. A customer service representative can make an appointment for you to apply in person or via telephone.
  • visit and apply for disability benefits online. (Note: you can only apply for SSDI, not SSI, online.)

Appealing a Disability Decision in Illinois

If you apply for Social Security or SSI disability in Illinois, you will receive a written decision on your claim in approximately 3-4 months. Approximately 36% of those who apply for disability in Illinois are approved for disability benefits without having to appeal. If your application for Social Security disability benefits is denied, you can still be approved for benefits through the SSA's appeals process.

To appeal a Social Security disability denial in Illinois, you need to complete a "Request for Reconsideration" form and submit this to the SSA within 65 days of the date on your denial letter.

If your reconsideration is denied, the next step in the Social Security appeals process is to appear for a disability hearing in front of an administrative law judge (ALJ). While more than half (approximately 51%) of Illinois disability hearings result in the claimant being awarded benefits, the wait for an ALJ hearing can be long. The average wait for a disability ALJ hearing in Illinois is 14 months, slightly shorter than the national average.

While an ALJ may occasionally announce their opinion at a disability hearing, in the majority of cases, you'll receive a written decision in the mail approximately 30 days after your hearing.

Illinois SSI Supplemental Payment

Illinois residents who are awarded SSI may be eligible for an additional payment from the state of Illinois, called the state supplemental payment (SSP) or AABD Cash Assistance. The amount of this Illinois SSI supplement is determined by subtracting the disabled individual's "monthly maintenance costs" from the amount of his or her SSI payment (plus any other income.) If these maintenance costs are higher than this combined amount, Illinois will pay the SSI recipient additional amounts for food, clothing, shelter, utilities, and more. The SSP is administered by the Illinois Department of Human Services (DHS). For more information, see AABD Cash Assistance allowances on the DHS website.
