Check your refund status through the Illinois Department of Revenue website

The Illinois Department of Revenue runs a refund tracker on its website where you can see where your state tax refund stands. Go to tax.illinois.gov, find the "Where's My Refund?" tool, and enter your Social Security number and the exact refund amount from your return. The tool tells you whether your refund is still being processed, has been approved, or has already been sent.

The tracker updates once per day, usually overnight. If you filed electronically, you can check status as soon as the department receives your return. If you mailed a paper return, allow at least two weeks before checking — the department needs time to scan and enter the information into their system.

You will need the refund amount as it appears on your tax return, not an estimate. If you are unsure of the exact figure, pull up your filed return or the confirmation email you received when you filed electronically.

What the tracker tells you at each stage

When you enter your information, the tracker displays one of several statuses. "Return received" means the department has your return but has not yet reviewed it. "Return approved" means the department has processed your return and your refund has been calculated. "Refund sent" means the money has left the department and is on its way to you.

The tracker also shows the refund amount and the method of delivery — direct deposit or check. If you chose direct deposit, the tracker may show an expected deposit date. If you chose a check, the tracker will tell you when the check was mailed, but delivery time depends on the postal service after that.

Some returns require additional review. If the tracker says "under review" or "pending verification," the department is checking information on your return — often income reported by employers, dependents claimed, or credits you took. This step can add one to three weeks to your timeline.

Timeline for Illinois state refunds

Illinois state refunds typically arrive within 30 days of approval if you filed electronically and chose direct deposit. Paper returns take longer because the department must first scan and manually enter the data, which adds two to four weeks before processing even begins.

If your return requires verification — for instance, if you claimed the Earned Income Tax Credit or if income reported on your return does not match what employers reported to the state — add another one to three weeks. Returns filed close to the April deadline move more slowly because the department processes a much higher volume in March and early April.

Direct deposit is faster than a mailed check. A check can take an additional one to two weeks after the department mails it, depending on postal service delays. If you have not received your refund within 45 days of the tracker showing "refund sent," contact the department.

What to do if the tracker shows an error or missing information

If the tracker says your return is "under review" or "pending verification" and you believe the information on your return is correct, you can contact 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, filing status, and the refund amount ready.

If the tracker shows a refund amount that does not match what you calculated, review your filed return first. The tracker shows what the department calculated based on the information you provided. If there is a discrepancy, it may mean the department adjusted your return based on information from employers or other sources.

Do not assume an error has occurred if the refund is smaller than expected. The department may have applied your refund to unpaid state income tax from a prior year, child support arrears, or other debts owed to the state. The tracker does not always explain these offsets, so a phone call to the department can clarify what happened.

If your refund does not arrive after the expected date

If the tracker shows "refund sent" but you have not received the money within the timeframe shown, first confirm that the delivery method and address are correct. If you chose direct deposit, verify that the account number and routing number on your return are accurate — a single wrong digit will cause the deposit to fail or go to the wrong account.

If the account information is correct and the deposit still has not arrived, contact your bank to ask whether the deposit was rejected or returned. The Illinois Department of Revenue can resend a direct deposit if the first attempt failed, but you will need to provide the bank's explanation of what went wrong.

If you chose a mailed check and it has not arrived within two weeks of the tracker showing "refund sent," contact the department. They can issue a replacement check or, in some cases, convert the refund to direct deposit if you provide banking information.

Refunds offset by state debts or child support

Illinois can intercept your state tax refund to pay back child support, unpaid state income tax from prior years, or certain other debts owed to the state. If this happens, the tracker may not clearly explain the offset — it may simply show a smaller refund amount than you expected, or the refund may not appear at all.

If you believe your refund was offset and you want to know why, call the Illinois Department of Revenue at 217-782-3336. They can tell you which debt the offset was applied to and provide information about the original debt. If the debt was child support, you may need to contact the Illinois Department of Human Services instead.

You cannot prevent an offset through the refund tracker. If you owe back child support or prior-year taxes, the offset will happen automatically. Your only option is to resolve the underlying debt with the appropriate agency.

Frequently Asked Questions

How often does the refund tracker update?

The Illinois Department of Revenue updates the "Where's My Refund?" tracker once per day, usually overnight. Check it the same time each day if you are monitoring your refund closely. Real-time updates are not available.

Can I check my refund status by phone?

Yes. 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 refund amount ready. Phone lines are busiest in March and April.

What if I filed a joint return — whose Social Security number do I use?

Use either spouse's Social Security number. The tracker will pull up the same refund information regardless of which number you enter, as long as you use the correct refund amount.

Why does the tracker say my refund was sent but I have not received it?

If you chose direct deposit, verify the account and routing numbers on your return are correct — a single wrong digit will cause the deposit to fail. If you chose a check, allow up to two additional weeks for postal delivery. If more than two weeks have passed since the tracker showed "refund sent," contact the department to request a replacement.

Can I change my refund to direct deposit after I file?

No. The delivery method is locked once you file. If you chose a check and want direct deposit instead, you must wait for the check to arrive, deposit it yourself, or contact the department to ask about alternatives — though they cannot may provide a change is possible.
