How to find your Illinois tax refund
The Illinois Department of Revenue runs a tool called Where's My Refund? that shows you the status of your state income tax refund. You enter your Social Security number, filing status, and the exact refund amount from your tax return, and the system tells you whether your refund has been processed, is still being reviewed, or has been sent.
The tool is free and available on the Illinois Department of Revenue website. You can check it as soon as you file your return, though the system will only show information once the department has received and begun processing your return. Most refunds are issued within 30 days of filing, but some take longer if the return needs review.
Key Takeaways
- The Illinois Department of Revenue's Where's My Refund tool requires your Social Security number, filing status, and the exact refund amount you claimed on your return.
- You can check your refund status anytime after filing, but the system will not show information until the department has received your return.
- Most refunds are issued within 30 days, though returns selected for review or containing errors may take longer.
- If your refund is delayed beyond 60 days, contact the Illinois Department of Revenue directly by phone or through their website.
What information you need to check your refund
Before you use Where's My Refund, gather three pieces of information from your tax return: your Social Security number, your filing status (single, married filing jointly, married filing separately, or head of household), and the exact dollar amount of the refund you claimed. The system will not accept approximate amounts — it needs the number exactly as it appears on your return.
If you filed electronically, you should have received a confirmation email with these details. If you filed on paper, look at the copy of the return you kept. Do not guess at the refund amount; an incorrect entry will cause the search to fail.
How long refunds typically take
The Illinois Department of Revenue aims to issue refunds within 30 days of receiving your return. If you filed electronically, the department usually receives it within a few days. If you mailed a paper return, allow extra time for postal delivery before the 30-day clock starts.
Some returns take longer. The department may select your return for review if certain items look unusual or if your income or deductions fall outside typical ranges. Returns with math errors, missing information, or inconsistencies with other documents (like W-2s or 1099s) also take longer to process. The Where's My Refund tool will show you if your return is under review.
What to do if your refund is delayed
If more than 60 days have passed since you filed and Where's My Refund shows no progress, or if the tool says your return is under review but you have not heard anything in several weeks, contact the Illinois Department of Revenue. You can call their individual income tax line during business hours or submit a question through their website.
When you contact them, have your Social Security number, filing status, and the refund amount ready. Be prepared to describe what the Where's My Refund tool showed when you last checked. If the department is reviewing your return, they may ask you to send additional documents or clarification by mail.
What happens if your refund was issued but you did not receive it
If Where's My Refund shows your refund was issued but the money has not arrived, the delay is usually in the mail or banking system, not with the state. Direct deposit refunds typically arrive within one to three business days after the department issues them. Paper checks can take one to two weeks depending on postal service.
If you chose direct deposit and the refund was issued more than a week ago, check with your bank to confirm the deposit has not already arrived and cleared. If you chose a paper check and it has been more than two weeks, contact the Illinois Department of Revenue with the date the refund was issued (shown in Where's My Refund) and ask them to investigate whether the check was lost in the mail.
Why your refund might be smaller than expected
Sometimes the refund amount shown in Where's My Refund is smaller than the amount you calculated when you filed. This usually happens because the state applied part of your refund to unpaid taxes, child support, student loans, or other debts owed to the state or federal government. The Illinois Department of Revenue is required by law to do this before sending you the remaining balance.
If you believe an offset was made in error, or if you want to know what debt caused the reduction, contact the Illinois Department of Revenue. They can explain which debt was offset and provide information about how to address it.
Frequently Asked Questions
Can I check my refund status on my phone?
Yes. The Illinois Department of Revenue's Where's My Refund tool works on any device with a web browser. You do not need to read an app — just visit the department's website and use the tool there.
What if I filed jointly with my spouse but only have one Social Security number?
Use the Social Security number of the person whose name appears first on the return. The system will ask for your filing status (married filing jointly) and will show the joint refund amount.
Do I need to create an account to use Where's My Refund?
No. The tool does not require you to create an account or log in. You enter your information each time you check, and the system shows you the status without storing your data.
What if I cannot remember the exact refund amount I claimed?
Look at the copy of your return or your filing confirmation email — both show the refund amount. If you filed through a tax preparer or software, you can log back into that account to find the amount. The system will not accept approximate figures.
Can I change my refund to direct deposit if I chose a paper check?
Once your return is filed, you cannot change the refund method. If you chose a paper check, the refund will be mailed. For future years, you can choose direct deposit when you file.
