Illinois Temporary Disability Insurance Is a State Program, Not Federal SSDI

Illinois has its own temporary disability insurance program, separate from Social Security Disability Insurance (SSDI). The program is called Temporary Disability Insurance (TDI), and it pays a portion of your wages if you cannot work due to a non-work-related illness or injury. You do not file through Social Security; you file through the Illinois Department of Financial and Professional Regulation (IDFPR).

TDI covers conditions like surgery recovery, pregnancy-related disability, or a serious illness that keeps you off work for at least 8 consecutive days. The program replaces roughly 60% of your average weekly wage, up to a state-set maximum. Benefits typically last up to 30 weeks in a 52-week period, though some situations extend longer.

Unlike SSDI, which requires proof of permanent or long-term disability, TDI is designed for temporary absences from work. If your condition is expected to last longer than a few months, you may eventually need to file for SSDI as well, but TDI is the first step for short-term income replacement in Illinois.

Key Takeaways

  • Illinois Temporary Disability Insurance (TDI) is a state program that replaces part of your wages when you cannot work due to illness or injury unrelated to your job.
  • You must have been unable to work for at least 8 consecutive days, and your employer must have had at least one employee during the week you became disabled.
  • File through the Illinois Department of Financial and Professional Regulation (IDFPR), not through Social Security, using Form IL 444 or by mail to the TDI division.
  • Your employer may file on your behalf, and many do automatically when they receive notice of your absence.
  • Processing typically takes 2 to 4 weeks after the IDFPR receives your complete claim.

Who Can File for Illinois TDI

You must meet several conditions to be covered under Illinois TDI. First, your employer must have had at least one employee on the payroll during the week you became disabled. Self-employed people and employees of very small operations may not be covered, so check with your employer's payroll or HR department.

Second, you must have been unable to work for at least 8 consecutive calendar days due to a condition unrelated to your job. Work-related injuries are covered by workers' compensation instead. The disability must be medically documented—your doctor must confirm you cannot perform your job duties.

Third, you must have been employed and earning wages in Illinois at the time you became disabled. If you were laid off or quit before the disability began, you do not meet the requirement. The program does not cover unemployment; it covers lost wages during a temporary medical absence.

Documents You Will Need to File

Gather these documents before you start your claim. You will need your Social Security number, your date of birth, and your employer's name and address. Have your most recent pay stub handy so you can provide your average weekly wage.

You will also need a medical certification from your doctor. The IDFPR provides Form IL 444-B for this purpose—your physician fills it out and confirms the dates you were unable to work and the expected duration of the disability. Some doctors' offices charge a small fee to complete this form, so ask when you call to request it.

If you are filing by mail, you will need to complete Form IL 444 (the Claim for Temporary Disability Insurance Benefits). If your employer files on your behalf, they handle the form, but you still need to provide the medical certification to your employer so they can submit it with their filing.

How to File Your Claim

You have two main routes: file online through the IDFPR website, or file by mail. The online route is faster. Go to the Illinois Department of Financial and Professional Regulation website, locate the TDI section, and look for the online claim portal. You will enter your personal information, employer details, and upload or reference your medical certification.

If you prefer to mail your claim, read Form IL 444 from the IDFPR website, complete it, and mail it along with your medical certification (Form IL 444-B) to the address listed on the form. Keep a copy for your records.

Many employers file claims on behalf of their employees automatically when they are notified of an absence. Ask your HR or payroll department whether they will file for you. If they do, you still need to provide the medical certification to them so they can include it with their filing. Do not assume your employer will file—confirm with them directly.

File as soon as possible after you have been unable to work for 8 days. The IDFPR can backdate benefits to the first day of your disability, but only if you file within a reasonable timeframe. Waiting months to file may result in lost benefits for the early weeks.

What Happens After You File

Once the IDFPR receives your complete claim—form, medical certification, and all required information—they typically process it within 2 to 4 weeks. During this time, a claims examiner reviews your medical documentation and verifies your employment and wage history with your employer.

If your claim is approved, the IDFPR will issue a information letter and begin sending benefit payments. Payments are usually made by check or direct deposit, depending on what you set up during filing. Your first payment may take an additional 1 to 2 weeks after approval.

If the IDFPR needs more information, they will contact you by mail or phone. Respond promptly—delays in providing medical records or clarification can slow your claim. If your claim is denied, the letter will explain the reason. You have the right to request reconsideration or appeal the decision.

How Much You Will Receive and for How Long

Illinois TDI replaces approximately 60% of your average weekly wage. The state sets a maximum weekly benefit amount that changes each year; check the IDFPR website for the current maximum. If your average weekly wage is below the maximum, you receive 60% of that wage. If it exceeds the maximum, you receive the maximum amount.

Benefits are available for up to 30 weeks within any 52-week period. Some situations—such as pregnancy-related disability or certain medical conditions—may extend benefits beyond 30 weeks, but this requires additional documentation and approval. Your claims examiner will advise you if your situation qualifies for an extension.

The benefit period runs from the first day you were unable to work, not from the day you filed. If you were disabled for 8 days before filing, those 8 days count toward your 30-week total, even if you did not receive payment for them yet.

How TDI Interacts with Other Benefits

If you are receiving unemployment benefits, you cannot receive TDI at the same time. TDI is for people who are temporarily unable to work due to medical reasons; unemployment is for people who are able and willing to work but cannot find a job. If you are on TDI, you are not required to search for work during your disability period.

If you are receiving workers' compensation for a work-related injury, you cannot receive TDI for the same period. Workers' compensation is the exclusive remedy for job-related disabilities in Illinois.

If your temporary disability extends beyond what TDI covers, or if your condition becomes permanent, you may be able to file for SSDI. TDI and SSDI can overlap during the transition period, but SSDI requires a separate process to Social Security and proof that your condition will last at least 12 months or result in death. Consult with a Social Security representative or disability advocate if you think your condition may may have access to for SSDI.

Frequently Asked Questions

Can my employer file the claim for me?

Yes, many employers file TDI claims on behalf of their employees. Contact your HR or payroll department and ask if they will file. If they agree, provide them with your completed medical certification form. If they decline or do not respond, you can file the claim yourself online or by mail.

What if my doctor will not fill out the medical certification form?

Contact your doctor's office and explain that the form is required for your disability benefits. Most offices complete these forms routinely, though some charge a small fee. If your regular doctor is unavailable, any licensed physician who treated you during your disability can complete the form.

How long does it take to get my first payment?

Processing typically takes 2 to 4 weeks after the IDFPR receives your complete claim. Once approved, your first payment may take an additional 1 to 2 weeks. In total, expect 3 to 6 weeks from filing to receiving your first benefit payment.

Can I work part-time while receiving TDI?

TDI is designed for people unable to work. If you return to work, even part-time, your benefits may be reduced or stopped. Report any work activity to the IDFPR when ready. Some partial-work situations may allow reduced benefits, but this depends on your specific circumstances and must be approved by the IDFPR.

What if my claim is denied?

The denial letter will explain the reason—for example, your employer may not be covered, your disability may not meet the 8-day requirement, or your medical certification may be incomplete. You have the right to request reconsideration by submitting additional information or documentation. Contact the IDFPR to ask about the appeal process for your specific situation.
