Yes, you can track your Illinois state tax refund online or by phone
The Illinois Department of Revenue runs a refund tracking tool that shows you the status of your state tax return and when your refund will arrive. You can check the status yourself without calling, and the tool updates regularly as your return moves through processing. The department also accepts phone calls if you prefer to speak with someone.
The tracking tool works whether you filed electronically or by mail, and whether you chose direct deposit or a paper check. You will need your Social Security number and the exact refund amount from your tax return to look up your status.
Key Takeaways
- The Illinois Department of Revenue's online refund tracker shows your return status and expected delivery date without requiring you to call.
- You need your Social Security number and the exact refund amount to use the tracker — the amount must match what you claimed on your return.
- Direct deposit refunds typically arrive within 10 to 21 days of approval, while paper checks take longer depending on mail delivery.
- If your refund is delayed beyond the expected timeframe, contact the department directly with your return information and filing date.
- The tracker updates during business hours, so checking on weekends or after 5 p.m. may show outdated information.
How to use the Illinois refund tracker
Go to the Illinois Department of Revenue website and locate the "Where's My Refund?" tool. Enter your Social Security number, the tax year you filed for, and the exact refund amount shown on your return. The tool will display your return's current status — whether it is still being processed, approved, or sent out.
The tracker shows different statuses depending on where your return is in the pipeline. "Return received" means the department has it but has not started processing. "Return approved" means the return passed review and your refund has been authorized. "Refund issued" means the money has been sent to you by direct deposit or check. The tool also displays the date your refund was issued and, for direct deposits, the expected arrival date.
Check the tracker during business hours — the system updates Monday through Friday between 8 a.m. and 5 p.m. Central Time. Checking outside these hours may show information from the previous business day.
Direct deposit versus paper check delivery times
If you chose direct deposit on your return, your refund typically arrives in your bank account within 10 to 21 days after the department marks it as issued. The exact timing depends on your bank's processing speed — some banks deposit funds the same day they receive the transfer, while others take one or two business days.
Paper checks take longer. Once the department issues your check, it enters the mail system. Delivery depends on where you live and how quickly the postal service processes it. Most checks arrive within two to three weeks of being issued, but mail delivery can vary. If you live far from Springfield or in a rural area, allow extra time.
The refund tracker will show you the date the refund was issued. If you chose direct deposit, add 10 to 21 days to that date for a reasonable arrival window. For checks, add two to three weeks and account for mail delivery delays in your area.
What to do if your refund is delayed
If the tracker shows your refund was issued but you have not received it after the expected timeframe, contact the Illinois Department of Revenue directly. Have your Social Security number, the tax year, and your filing date ready. The department can tell you whether the refund is still in transit or if there was a problem with the delivery address or bank account information.
For direct deposit delays, ask the department to confirm the bank account number on file. If the account number is wrong, the refund may have been rejected by your bank and sent back to the department. The department can reissue the refund to the correct account or send a check instead.
For check delays, the department can file a trace with the postal service if the check has been missing for more than three weeks after issuance. This process takes time, but it creates an official record. If the check is confirmed lost, the department can issue a replacement check or direct deposit.
Reasons your refund might take longer than expected
Some returns require additional review before approval. The department may need to verify information on your return, match it against other records, or request supporting documents. If your return is flagged for review, the tracker will show "Return under review" or similar language. This can add two to four weeks to your timeline.
Returns with errors — such as a mismatched Social Security number, incorrect income figures, or missing information — also take longer. The department will contact you by mail if they need you to correct something. You must respond within the timeframe they provide, or your refund will be delayed further.
If you claimed certain credits or deductions, the department may hold your return for verification. This is routine and does not mean you did anything wrong — it just means the department wants to confirm the numbers before releasing your refund.
How to contact the Illinois Department of Revenue about your refund
Call the department's refund line at 217-782-3336. Have your Social Security number, filing date, and the refund amount ready. The line is open Monday through Friday, 8 a.m. to 5 p.m. Central Time. Wait times can be long during tax season, especially in March and April.
You can also mail a written inquiry to the Illinois Department of Revenue, PO Box 19044, Springfield, IL 62794-9044. Include your name, Social Security number, tax year, and a description of your question. Written inquiries take longer to process — typically two to three weeks — so use this method only if you cannot reach the phone line or prefer written communication.
The department does not respond to email inquiries about individual refunds. Use the online tracker or phone line for the fastest response.
What information you need before you start tracking
Gather your Social Security number and the exact refund amount from your tax return before you use the tracker. The amount must be precise — if you enter $1,200 but your return shows $1,199.50, the tracker will not find your return. Check your filed return or the confirmation notice you received when you filed.
If you filed electronically, you should have received an email confirmation with your filing date and refund amount. If you filed by mail, the confirmation notice came in the mail or you can request one from the department. If you cannot find the exact amount, call the department and they can tell you what to enter.
You will also need to know the tax year you filed for — usually the year before the current year. For example, if you are tracking a 2023 tax refund, you filed in early 2024.
Frequently Asked Questions
Can I track my refund if I filed a joint return with my spouse?
Yes, but you can only use one Social Security number at a time in the tracker. Use either your number or your spouse's number — the tracker will show the status of the entire joint return. The refund amount will be the total for both of you, not split by person.
What does "return under review" mean and how long will it take?
It means the department is verifying information on your return before approving your refund. This can happen for many reasons — mismatched income, claimed credits that need verification, or routine audits. Most reviews take two to four weeks, but complex cases can take longer. The department will contact you if they need additional information from you.
My refund was issued but I still haven't received it after three weeks. What should I do?
Contact the Illinois Department of Revenue at 217-782-3336 with your Social Security number and filing date. They can confirm whether the refund is still in transit, check if there was a delivery problem, or file a trace with the postal service if your check is lost. Have them verify your bank account or mailing address is correct on file.
Can I change my refund to direct deposit if I originally chose a paper check?
No, you cannot change the delivery method after you file. If your return was already processed and issued as a check, the refund will arrive by mail. For future years, you can choose direct deposit when you file your next return.
Why does the tracker say my refund was issued but my bank shows no deposit?
Direct deposits can take 10 to 21 days to appear in your account after the department issues them. If it has been less than three weeks, wait a few more business days. If it has been longer, contact the department to confirm your bank account number is correct — if it is wrong, the deposit was rejected and the department needs to reissue it.
