Where to check your Illinois tax refund
The Illinois Department of Revenue runs a free online tool called Where's My Refund? that shows you the status of your state tax refund. You can access it on the department's website without logging in — you only need your Social Security number, filing status (single, married filing jointly, etc.), and the exact refund amount from your tax return.
The tool updates every business day and tells you whether your refund is still being processed, has been approved, or has already been sent. If your refund was mailed as a paper check, the tool will show you the date it was sent. If it was deposited directly to your bank account, you'll see the deposit date.
You can also call the Illinois Department of Revenue at 1-800-732-8866 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time) and speak to someone who can look up your refund status over the phone. Have your Social Security number and the refund amount ready when you call.

How long Illinois tax refunds typically take
A straightforward Illinois state tax return usually takes 30 days or less from the date the department receives it to process and approve your refund. If you filed electronically, the department receives it almost immediately. If you mailed a paper return, allow 1 to 2 weeks for postal delivery before processing begins.
Once the department approves your refund, the delivery method determines how long you wait. Direct deposit refunds hit your bank account within 1 to 3 business days after approval. Paper checks take 7 to 10 business days to arrive by mail after the department sends them.
Amended returns, returns with errors, and returns that trigger additional review take longer — sometimes 60 days or more. The Where's My Refund? tool will show you if your return is under review, but it won't always tell you why. If the tool shows your return is still processing after 60 days, call the department to find out what's holding it up.
What to do if your refund is delayed
If the Where's My Refund? tool shows no record of your return at all, the department may not have received it yet. If you filed electronically, wait at least 24 hours and check again. If you mailed a paper return, wait 2 to 3 weeks for postal delivery, then check again. If the tool still shows nothing after that timeframe, call 1-800-732-8866 to confirm the department received your return.
If the tool shows your return is processing but more than 60 days have passed since you filed, call the department. Delays this long usually mean your return was flagged for review — the department may need additional documents from you, or there may be an error on the return itself. The department will tell you what's needed and how to send it.
If the tool shows your refund was sent but you haven't received it after the expected timeframe, the check may have been lost in the mail or your bank may have rejected a direct deposit. Call the department with the refund date shown in the tool. They can issue a replacement check or investigate why the direct deposit failed.
Direct deposit versus paper check refunds
Illinois offers both direct deposit and paper check refunds. Direct deposit is faster — your money arrives 1 to 3 business days after approval. Paper checks take 7 to 10 business days to arrive by mail after the department sends them, and you have to be home to receive them.
When you file your return, you choose which method you want. If you chose direct deposit, make sure the bank account and routing number on your return are correct — if they're wrong, the deposit will fail and the department will have to mail you a check instead, which adds another 7 to 10 days.
If you filed your return but didn't choose a refund method, the department will mail you a paper check by default. You cannot change your refund method after you file, so if you want direct deposit next year, remember to select it when you prepare your return.
What information you need to check your refund
To use the Where's My Refund? tool, have these three things ready: your Social Security number, your filing status (single, married filing jointly, married filing separately, or head of household), and the exact refund amount from your tax return. The amount must match exactly — if you enter $1,500 but your refund is $1,499, the tool won't find your return.
If you don't remember the exact refund amount, look at your tax return itself or the confirmation email or letter you received from the department. If you filed electronically, your tax software should have a copy of your return. If you mailed a paper return and don't have a copy, you can order a transcript from the Illinois Department of Revenue that will show the refund amount.
When you call the department at 1-800-732-8866, have the same information ready. The representative will ask for your Social Security number and filing status to pull up your account, then they can tell you the refund status without needing the exact amount.
Refunds for amended or corrected returns
If you filed an amended Illinois return (Form IL-1040-X) to correct an error or add missing information, your refund will take longer than a standard return. Amended returns are processed manually and typically take 60 to 90 days from the date the department receives them.
The Where's My Refund? tool may not show an amended return right away. If you filed an amended return and the tool shows no record of it after 2 weeks, call the department to confirm they received it. Once they have it, the tool should update within a few days to show it's under review.
If the department owes you money on an amended return and also has a debt against you (such as unpaid child support or a prior-year tax debt), they may hold your refund to offset that debt. The department will send you a notice explaining the offset. If you believe the offset was wrong, you can contact the department to dispute it.
Frequently Asked Questions
Can I check my refund status if I filed jointly with my spouse?
Yes. Use either spouse's Social Security number in the Where's My Refund? tool — the tool will show the same refund status either way. When you call the department, you can use either Social Security number as well. The refund is issued once, not split between two accounts, so you only need to track one status.
What if the Where's My Refund? tool says my refund was sent but I never got it?
If direct deposit was rejected, the department will mail a paper check instead, which adds 7 to 10 days. If a paper check was lost in the mail, call 1-800-732-8866 with the refund date shown in the tool and request a replacement. The department can issue a new check or investigate further if needed.
Do I need to create an account to use Where's My Refund?
No. The tool is free and does not require you to log in or create an account. You only need your Social Security number, filing status, and the refund amount from your return. The tool is available on the Illinois Department of Revenue website.
How far back can I check refund status for old tax years?
The Where's My Refund? tool typically shows refunds from the current and prior tax year. For refunds older than that, call the Illinois Department of Revenue at 1-800-732-8866 and they can look up the status or confirm whether the refund was issued.
What if I moved after I filed my return?
If you chose direct deposit, your refund will go to the bank account you listed on your return regardless of where you live. If you chose a paper check and moved, the check may be delayed or returned to the department. Update your address with the post office so mail is forwarded, or call the department to provide your new address before your refund is sent.
