Check your refund status through the Illinois Department of Revenue website
The Illinois Department of Revenue operates a refund tracker on its website where you can see the status of your state income tax refund. Go to tax.illinois.gov, find the "Where's My Refund?" tool, and enter your Social Security number and the refund amount you expect. The tool will tell you whether your refund is still being processed, has been approved, or has already been issued.
The tracker updates once per day, usually overnight. If you filed electronically, your refund typically processes faster than a paper return. The Department of Revenue processes returns in the order they are received, not by filing date.
If the tool shows your refund as issued but you have not received it, check the payment method you selected when you filed. Refunds are sent by direct deposit to your bank account or by paper check mailed to your address on file.

- Electronic returns typically process faster than paper returns, and the Department of Revenue processes returns in the order received.
- Refunds are issued by direct deposit or paper check depending on the method you selected when filing.
- If your refund shows as issued but has not arrived, contact your bank or check your mailing address on file with the Department of Revenue.
- Processing times vary depending on return complexity, but most refunds are issued within 30 to 60 days of filing.
How long Illinois refunds typically take to arrive
Processing time depends on whether you filed electronically or by mail and whether your return required additional review. Electronic returns without errors usually process within 30 days. Paper returns take longer because they must be scanned and entered into the system manually, often 60 days or more.
Some returns trigger additional verification steps. If the Department of Revenue needs to confirm information on your return — such as income reported by your employer or claimed dependents — processing can take several additional weeks. You will receive a letter if your return requires this review.
Returns filed close to the April 18 deadline take longer to process because the Department of Revenue receives a high volume all at once. Filing earlier in the tax season generally results in faster processing.
What to do if your refund is delayed beyond the expected timeframe
If your refund has not arrived within 60 days of filing electronically or 90 days of filing by mail, contact the Illinois Department of Revenue directly. Call their taxpayer assistance line at 217-782-3336 during business hours, Monday through Friday, 8 a.m. to 4:30 p.m. Central Time. Have your Social Security number, filing status, and expected refund amount ready.
The Department of Revenue can tell you whether your return is still in the queue, has been flagged for review, or has been issued but not yet received. If your refund was issued by check, they can confirm the mailing date and help you determine whether it was lost in the mail. If it was issued by direct deposit, they can verify the bank account information on file.
If you filed by mail and your return has not been received, ask whether it arrived at the Department of Revenue office. Paper returns can be delayed in transit or lost. The Department of Revenue can advise you on whether to file an amended return or take other steps.
Direct deposit versus paper check refunds
When you filed your return, you chose how to receive your refund. Direct deposit sends the money to your bank account and is the fastest method — refunds typically arrive within 5 to 10 business days after the Department of Revenue issues them. Paper checks are mailed to your address on file and take 7 to 14 business days to arrive after being issued, depending on postal service speed.
If you selected direct deposit but entered an incorrect bank account number or routing number, your refund will be rejected by your bank and returned to the Department of Revenue. This adds 2 to 3 weeks to the process. The Department of Revenue will then issue a paper check to your mailing address.
If you moved after filing, make sure your current address is on file with the Department of Revenue. Paper checks are mailed to the address listed on your return. If the address is outdated, the check may be returned as undeliverable. Contact the Department of Revenue to update your address if you have moved.
If your refund was lost or never received
If the "Where's My Refund?" tool shows your refund as issued but you have not received it after the expected timeframe, the check may have been lost in the mail or your direct deposit may have failed. Contact the Department of Revenue at 217-782-3336 with your Social Security number and the date shown as the issue date.
For direct deposit refunds that did not arrive, the Department of Revenue will verify the bank account information on your return. If the account number or routing number was incorrect, ask them to issue a paper check instead. For paper checks that did not arrive, ask whether the check can be reissued or whether you need to file a claim.
Keep any documentation you have — your filed return, the confirmation number if you filed electronically, or the "Where's My Refund?" screenshot showing the issue date. This information helps the Department of Revenue locate your refund and resolve the issue.
Amended returns and refund delays
If you filed an amended return after your original return, your refund will be delayed. Amended returns are processed separately and take longer than original returns. The Department of Revenue processes amended returns in the order received, which can add 8 to 12 weeks to the timeline.
The "Where's My Refund?" tool will show the status of your most recent return — either your original or amended return, whichever was filed last. If you filed an amended return, the tool may show your original refund as issued while your amended refund is still processing. You will receive only one refund, which reflects the changes on your amended return.
If you need to amend your return, file it as soon as possible. The longer you wait, the longer the Department of Revenue takes to process it after it arrives.
Frequently Asked Questions
Why does the refund tracker say my refund was issued but I haven't received it?
If your refund was issued by direct deposit, it may still be in transit to your bank — this usually takes 5 to 10 business days after the issue date. If it was issued by check, the mail can take 7 to 14 business days. Check the issue date shown in the tracker and count forward. If more time has passed, contact the Department of Revenue to confirm the payment method and account information.
Can I get my refund faster if I file electronically?
Yes. Electronic returns process much faster than paper returns because they go directly into the Department of Revenue's system. Most electronic returns without errors are processed within 30 days. Paper returns can take 60 to 90 days because they must be scanned and manually entered first.
What happens if I made a mistake on my return?
If you made an error that affects your refund, file an amended return using Form IL-1040-X. Amended returns are processed separately and take longer — usually 8 to 12 weeks. The Department of Revenue will issue one refund that reflects all changes from both your original and amended returns combined.
How do I know if my return is being reviewed?
The Department of Revenue sends a letter if your return requires additional verification or review. Check your mail for any correspondence from the Department of Revenue. You can also call 217-782-3336 to ask whether your return is under review. If it is, ask what information they need and when you can expect a decision.
What if I filed by mail and my return never arrived?
Call the Department of Revenue at 217-782-3336 and provide your Social Security number. They can check whether your return was received. If it was not, they can advise you on whether to file again or take other steps. Keep a copy of your return for your records.
