How to find your Illinois tax refund
The Illinois Department of Revenue runs a tool called Where's My Refund? that shows the status of your state income tax refund. You can check it on the department's website without logging in — you only need your Social Security number and the exact refund amount from your tax return.
The tool updates once per day, usually overnight. If you filed electronically, your refund typically processes within 21 days. If you filed on paper, it can take up to 60 days. The status page will tell you whether your return is still being processed, approved, or already sent to your bank or mailed as a check.
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) and speak with someone who can look up your refund status by phone.
Key Takeaways
- The Illinois Department of Revenue's Where's My Refund? tool is free and requires only your Social Security number and refund amount.
- Electronic returns typically show a refund within 21 days; paper returns take up to 60 days.
- The status page updates once daily and will show whether your return is processing, approved, or already sent.
- If the online tool does not show your refund after the expected timeframe, contact the department by phone or check whether you owe back taxes or child support.
What information you need to check your status
Before you use Where's My Refund?, gather two pieces of information from your tax return: your Social Security number and the exact refund amount you claimed. The refund amount must match what you entered on your return — if you entered $1,250 but type $1,251, the tool will not find your return.
If you filed jointly with a spouse, you can use either spouse's Social Security number. If you cannot remember the exact refund amount, check your copy of the return you filed, your email confirmation if you filed electronically, or the paper copy if you filed by mail.
When to expect your refund
Illinois processes refunds on different timelines depending on how you filed. If you filed your return electronically and chose direct deposit to your bank account, the refund typically arrives within 21 days of the Illinois Department of Revenue receiving your return. If you chose a paper check by mail, add another 7 to 10 business days for postal delivery after the refund is approved.
Paper returns filed by mail take longer because the department must receive the physical form, scan it, and enter the information into their system before processing begins. These returns usually take up to 60 days from the date received. If you filed on paper and it has been more than 60 days, contact the department to confirm they received your return.
The Where's My Refund? tool will show you the current step: whether the return is still being processed, has been approved and is waiting to be sent, or has already been sent to your bank or the mail.
Why your refund might be delayed
The Illinois Department of Revenue may hold or delay your refund if you owe back taxes to the state, owe child support, or have other debts that the state can offset against your refund. This is called a refund offset. If this applies to you, the Where's My Refund? tool will show a message explaining the delay.
Your refund can also be delayed if there is a mismatch between your return and your W-2 forms or other income documents. The department will contact you by mail if they need more information or if they found an error on your return. Check your mailbox for any letters from the Illinois Department of Revenue.
If your return was filed on paper and you have not heard anything after 60 days, it is possible the department did not receive it. Contact them by phone to confirm receipt and ask whether they need you to file again or provide a copy.
Direct deposit versus check by mail
If you chose direct deposit on your return, your refund goes straight to your bank account once approved. This is the fastest method and usually takes 21 days total from when the department receives your return. You will see the money appear in your account; there is no separate step you need to take.
If you chose a paper check, the department mails it to the address on your return. Once approved, the check is printed and mailed, which adds 7 to 10 business days. The Where's My Refund? tool will show when the check has been mailed, but it will not give you a tracking number — you can only watch for it to arrive in your mailbox.
If you filed electronically but did not provide banking information, the department will mail a check by default. If you are still waiting for a check that should have arrived, contact the department to confirm the mailing address and ask whether they can reissue it.
What to do if your refund is missing or never arrives
If the Where's My Refund? tool shows your refund was sent but you never received it, first check that you are looking at the correct address. The refund was mailed to the address you listed on your return, not necessarily your current address. If you moved after filing, the check may have gone to your old address.
If the check was sent to the correct address and you still have not received it after 10 business days, contact the Illinois Department of Revenue at 217-782-3336. They can check whether the check was cashed and, if not, can stop payment and issue a replacement. If the check was cashed but you did not receive it, you will need to report it as fraud.
If the Where's My Refund? tool shows your refund was approved but has not been sent yet, and it has been longer than the expected timeframe, call the department to ask why. They can tell you if there is a hold on your account or if there is a processing delay.
Frequently Asked Questions
Can I check my refund status if I filed jointly with my spouse?
Yes. You can use either spouse's Social Security number and the refund amount from your joint return. The status will be the same regardless of which Social Security number you enter, since the refund is tied to the return itself, not to one person.
What if the Where's My Refund? tool says it cannot find my return?
Double-check that you entered your Social Security number and refund amount exactly as they appear on your return. If both are correct and the tool still does not find it, your return may not have been received yet, or it may not have been processed into the system. Call 217-782-3336 to confirm the department received your return and ask when it should appear in the tool.
How long does it take to get a refund if I owe child support?
If you owe child support, the Illinois Department of Revenue will offset your refund to pay what you owe. This delay is separate from normal processing time. The department will send you a notice explaining the offset. Contact the Illinois Department of Financial and Professional Regulation or your local child support enforcement office to find out how much is being offset and when the remaining refund, if any, will be sent.
Can I cancel my refund and get my money back as a payment instead?
No. Once you file your return and claim a refund, you cannot cancel it. If you overpaid your taxes, the refund is the only way to get that money back. You can choose how to receive it — direct deposit or check — but you cannot change it to a payment or keep it with the state.
What if I filed my return but never got a confirmation?
If you filed electronically, you should have received an email confirmation with a confirmation number. Check your spam folder. If you filed on paper, the department does not send a confirmation — you only know your return was received when it appears in the Where's My Refund? tool or when you receive a letter from the department. Call 217-782-3336 with your Social Security number to confirm receipt.
