Call the Illinois Department of Revenue at 217-782-3336 to check your state refund status
The Illinois Department of Revenue runs the state refund system and answers phone questions about where your money is. The main line is 217-782-3336. You can also reach them at 1-800-732-8866 if you are calling from outside the Springfield area. Have your Social Security number and the tax year you filed for ready when you call.
The phone lines are open Monday through Friday, 8 a.m. to 4:30 p.m. Central Time. Wait times are usually shortest early in the morning or late in the afternoon. If you reach a busy signal, the system will not hold you in a queue — you will need to call back.
The department also has a refund status tool on its website at www2.illinois.gov/rev, where you can enter your information without waiting on hold. The online tool updates at the same time the phone representatives access the same data, so both methods show the current status.

What information you need before calling
The representative will ask for your Social Security number to pull up your account. They will also need to know which tax year you are asking about — for example, the 2023 tax year (filed in 2024) or the 2024 tax year (filed in 2025). If you filed jointly with a spouse, either Social Security number will work.
Have your tax return in front of you if possible. The representative may ask which form you filed (Form IL-1040 for residents, Form IL-1040-NR for nonresidents) or details about your filing status, though usually just the Social Security number is enough to locate your account.
What the refund status will tell you
When you call, the representative will tell you one of several things: whether your return has been received and is being processed, whether it has been approved and is waiting to be sent out, or whether it has already been issued and the payment method (check or direct deposit).
If your refund has been issued by direct deposit, you will receive a date when it should hit your bank account. Direct deposits typically arrive within 3 to 5 business days after the state sends them. If your refund is being mailed as a check, the representative will give you an expected mailing date, and you should receive it within 7 to 10 business days after that.
If the representative tells you your return is still being processed, they can explain what stage it is in — for example, whether it is waiting for verification of income or whether there is a hold because of a data mismatch with federal records.
Why your refund might be delayed
Illinois refunds are held up most often because of a discrepancy between what you reported and what the IRS reported to the state. This happens when your federal return shows different income, deductions, or credits than your state return. The state has to verify the information with the IRS before releasing your money.
Refunds are also delayed if you claimed the Earned Income Tax Credit (EITC) or the Child and Dependent Care Credit. Illinois holds these returns longer for fraud prevention. The state also processes paper returns more slowly than electronic ones — if you mailed in your return, expect an extra 2 to 4 weeks compared to an e-filed return.
If you owe money to the state — for example, back child support, student loan debt, or a prior-year tax bill — the state may hold your refund to offset what you owe. The representative can tell you if this is happening and what debt is being collected.
Using the online refund tracker instead of calling
The Illinois Department of Revenue website has a refund status tool that works 24 hours a day. Go to www2.illinois.gov/rev and look for the "Check Your Refund Status" link. Enter your Social Security number and tax year, and the system will show you the same information a phone representative would give you.
The online tool is faster if you just need a quick status check and do not have questions. It updates throughout the day as returns move through the system. If you need to speak with someone — for example, to understand why your refund is delayed or to report a missing refund — the phone line is your better option.
What to do if your refund is missing or very late
If the state says your refund was issued but you have not received it after the expected timeframe, call back and ask the representative to file a trace. A trace is a formal request to locate a lost check or investigate a failed direct deposit. The department will research where your payment went and contact you with findings.
If your refund was supposed to arrive by direct deposit and did not show up, make sure you gave the state the correct bank account and routing number on your return. A common mistake is transposing a digit. The representative can confirm what account number the state has on file.
If a check was lost in the mail, the state can issue a replacement. This usually takes 4 to 6 weeks. You will need to sign a form confirming you did not receive the original check, and the state will send a new one to your address on file.
Other ways to reach Illinois Department of Revenue
If you prefer not to call, you can mail a written question to the Illinois Department of Revenue, P.O. Box 19044, Springfield, IL 62794-9044. Include your name, Social Security number, tax year, and a description of what you need. Responses by mail take 4 to 6 weeks.
The department also has a contact form on its website where you can submit questions online. Responses typically come within 5 to 7 business days, which is faster than mail but slower than a phone call.
Frequently Asked Questions
How long does Illinois usually take to send out a refund?
Illinois aims to process and issue refunds within 30 days of receiving your return, but the timeline depends on how you filed. E-filed returns are processed faster than paper returns. If you claimed certain credits or if there is a discrepancy with your federal return, processing takes longer — sometimes 6 to 8 weeks or more.
Can I check my refund status without calling?
Yes. The online refund tracker at www2.illinois.gov/rev shows your status 24 hours a day. You enter your Social Security number and tax year, and the system displays the same information a phone representative would give you. The online tool is often faster if you just need a quick status check.
What if the department says my refund was sent but I never got it?
Call back and ask the representative to file a trace. This is a formal search for a lost check or failed direct deposit. The department will investigate and contact you with what they find. If a check was lost in the mail, they can issue a replacement, though this takes 4 to 6 weeks.
Why is my refund taking so long?
Common reasons include a mismatch between your state and federal returns, claiming the EITC or child care credits (which trigger extra review), filing by paper instead of electronically, or a hold because you owe money to the state. Call 217-782-3336 and the representative can tell you specifically what is holding up your refund.
Do I need to file anything else or take any action to get my refund?
No. Once you have filed your return, the state processes it automatically. You do not need to do anything except wait. If there is a problem — like a missing piece of information — the department will contact you by mail. Do not respond to unsolicited calls or emails claiming to be from the state asking for payment or personal information.
