Where to check your Illinois refund status
The Illinois Department of Revenue runs a refund tracker on their website at tax.illinois.gov. Go to the homepage, look for "Where's My Refund?" or "Refund Status," and enter your Social Security number and the refund amount you expect. The tool tells you whether your return is still being processed, approved, or sent to your bank.
You can also call the Illinois Department of Revenue at 217-782-3336 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time). Have your Social Security number and expected refund amount ready. Wait times are usually shorter early in the week and early in the day.
The online tool is faster if you know your expected refund amount. The phone line is useful if you have questions about why a refund is delayed or if the online tool shows no record of your return.

How long Illinois takes to process refunds
Illinois aims to process returns within 30 days of receipt, but the actual timeline depends on how you filed and how you want your refund. Returns filed electronically move through the system faster than paper returns. A return filed in early February might be processed by early March, while one filed in late April could take longer because the department receives more returns as the important date approaches.
If you chose direct deposit on your return, the refund reaches your bank account within a few business days of approval. If you requested a check, the state mails it, which adds another 7 to 10 business days depending on postal service. A refund approved on March 15 might not arrive by mail until late March or early April.
The "Where's My Refund?" tool shows you which stage your return is in: received, under review, approved, or sent. If it shows "approved" but you have not received the money, check whether you chose direct deposit or a check, and count forward from the approval date.
What to do if your refund is delayed
If your return has been in the system for more than 30 days and the online tool shows no status, or if it shows "under review" after six weeks, call the Department of Revenue at 217-782-3336. Have your Social Security number, filing status, and the date you filed ready. The representative can see whether there is a hold on your return or whether the system has not yet recorded it.
Common reasons for delays include math errors on the return, a mismatch between the name and Social Security number you reported, or a missing signature. The department will contact you by mail if they need more information, so check your mailbox regularly during tax season.
If you filed a paper return and it has been more than 45 days, the return may not have been entered into the system yet. Ask the representative whether they can see a record of it. If not, you may need to file again electronically or by mail with a note explaining that you are resubmitting.
Direct deposit versus check refunds
When you file your Illinois return, you choose how to receive your refund. Direct deposit means the state sends the money straight to your bank account. This is faster — usually 3 to 5 business days after approval — and there is no risk of a check getting lost in the mail. You need to provide your bank account number and routing number on your return.
A check refund means the state mails you a physical check. This takes longer because the check has to be printed, mailed, and then deposited or cashed by you. The entire process from approval to money in your account typically takes 10 to 14 business days. If the check is lost or delayed in the mail, you have to contact the Department of Revenue to request a replacement.
If you are unsure which method you chose, the "Where's My Refund?" tool sometimes shows it, or you can call the department to ask. If your refund was approved weeks ago and you still have not received it, and you chose direct deposit, contact your bank to confirm they received the transfer. If you chose a check and it has been more than two weeks since approval, call the department to request a replacement check or ask them to reissue it as a direct deposit.
What information you need to check your status
To use the "Where's My Refund?" tool, you need two pieces of information: your Social Security number (or Individual Taxpayer Identification Number if you do not have an SSN) and the refund amount you expect. The refund amount is the number shown on your return — the total you are owed after taxes paid and credits claimed.
If you do not remember the exact amount, you can estimate it, but the tool works best with the precise figure. If you filed jointly with a spouse, use the total household refund amount, not half of it. If you are not sure what amount you entered on your return, look for your filing confirmation email (if you filed electronically) or the copy of the return you kept.
When you call the Department of Revenue, have the same information ready, plus the date you filed if you remember it. If you filed by mail, knowing the date you mailed it helps the representative narrow down when it likely arrived.
If your return was rejected or not received
Sometimes a return does not make it into the system at all. This happens most often with paper returns that are lost in the mail or arrive damaged. If you filed by mail more than 45 days ago and the "Where's My Refund?" tool shows no record, call 217-782-3336 and ask whether they have received it.
If they have no record, you have two options: file again electronically through a tax software provider or the IRS Free File program, or file another paper return by mail. If you file again, note on the new return that you are resubmitting because the original did not arrive. Keep a copy of the original return for your records.
If you filed electronically and the tool shows no status after a week, the return may not have been accepted by the state system. Check your email for a rejection notice from the tax software you used. The notice will explain what was wrong — usually a formatting error or a mismatch in personal information. You can then correct it and resubmit.
Frequently Asked Questions
Can I check my refund status on my phone?
Yes. The Illinois Department of Revenue's website at tax.illinois.gov works on mobile browsers. You enter the same information — Social Security number and expected refund amount — and get the same status information. There is no separate app; use the website through your phone's browser.
What does "under review" mean for my refund?
It means the Department of Revenue has received your return and is checking it for errors or verifying the information you reported. This stage usually lasts a few days to a week. If it stays "under review" for more than two weeks, call the department to ask whether there is a specific issue holding up processing.
How do I know if my refund was sent by direct deposit or check?
The "Where's My Refund?" tool sometimes shows the payment method. If it does not, call 217-782-3336 and provide your Social Security number. The representative can tell you which method you chose on your return and, if it was approved, when the payment was sent.
What if I moved after I filed and the check was mailed to my old address?
Contact the Department of Revenue at 217-782-3336 and tell them your refund was mailed to an old address. They can issue a replacement check to your current address or reissue the refund as a direct deposit if you provide your bank information. Bring a piece of mail showing your new address when you call.
Can I track my refund check through the mail?
No. Once the state mails the check, you cannot track it the way you would a package. If the check does not arrive within 14 business days of the approval date shown in "Where's My Refund?", call the Department of Revenue to request a replacement or to have them reissue it as a direct deposit instead.
