Illinois tax refunds typically arrive within 2 to 8 weeks after you file, depending on how you file and how the state processes your return
The timeline depends on three things: whether you file electronically or by mail, whether you choose direct deposit or a check, and whether the Illinois Department of Revenue needs to review your return for accuracy. Direct deposit is faster than a mailed check. E-filed returns are processed faster than paper returns. If your return is straightforward with no errors, you will be at the shorter end of the range.
The Illinois Department of Revenue publishes processing times on its website, but those times assume your return has no issues. If the department flags something for review—a mismatch between your W-2s and your reported income, for example—your refund will be delayed while they investigate. You can check the status of your specific return using the Where's My Refund tool on the Illinois Department of Revenue website.
Key Takeaways
- E-filed returns with direct deposit typically arrive within 2 to 4 weeks; paper returns take 6 to 8 weeks or longer.
- The Illinois Department of Revenue's Where's My Refund tool shows your return status and estimated delivery date once processing begins.
- If your return is flagged for review—usually because of mismatched income or missing documentation—your refund will be delayed by several weeks.
- Direct deposit deposits money into your bank account; a mailed check takes an additional 5 to 7 business days after the state issues it.
- You need your Social Security number and the exact refund amount from your return to check status online.
E-filed returns arrive faster than paper returns
If you file electronically through tax software or a tax professional, the Illinois Department of Revenue begins processing your return within 24 hours. Most e-filed returns are processed and approved within 2 to 4 weeks if you choose direct deposit. If you request a mailed check instead, add 5 to 7 business days after the state issues the check for it to arrive at your address.
Paper returns filed by mail take much longer. The state must receive your return, open it, scan it, and enter the information into its system before processing begins. This alone can take 2 to 3 weeks. After that, processing takes another 4 to 6 weeks. Total time for a paper return is typically 6 to 8 weeks, and sometimes longer if mail is slow or the return is incomplete.
Direct deposit is faster than a mailed check
When you choose direct deposit, the Illinois Department of Revenue deposits your refund directly into your bank account once your return is approved. This usually happens within 2 to 4 weeks for e-filed returns. Your bank may hold the deposit for 1 to 2 business days before it shows in your account, but the money is yours once the state initiates the transfer.
A mailed check takes longer. After the state approves your return, it prints and mails the check to the address on your return. The check then travels through the postal system, which typically takes 5 to 7 business days. If you move or the address on your return is incorrect, the check may be returned to the state, and you will need to contact them to request a reissue.
Returns flagged for review are delayed by several weeks
The Illinois Department of Revenue reviews some returns before issuing a refund. Common reasons include a mismatch between your W-2s and your reported income, missing or incomplete documentation, or a discrepancy with a prior year's return. If your return is flagged, the state will send you a notice by mail explaining what information is needed.
You must respond to the notice within the timeframe stated—usually 30 days. If you provide the requested information quickly, the review may be completed within 2 to 4 weeks. If you miss the deadline or the state needs additional follow-up, the delay can stretch to 8 weeks or longer. Check your mail regularly after filing, and respond to any notice from the Illinois Department of Revenue as soon as possible.
How to check your refund status online
The Illinois Department of Revenue's Where's My Refund tool lets you check the status of your return at any time. Go to the Illinois Department of Revenue website and select the Where's My Refund option. You will need your Social Security number and the exact refund amount from your tax return.
The tool shows whether your return has been received, is being processed, has been approved, or has been issued. If your return is approved, the tool displays the expected delivery date. If there is a delay or your return is flagged for review, the tool will show that status as well. Check the tool every few days if you are waiting for your refund, especially if you filed early in the tax season when processing times are longer.
What to do if your refund is late
If your refund does not arrive by the date shown in the Where's My Refund tool, or if the tool shows no status after 4 weeks, contact the Illinois Department of Revenue. You can call their refund hotline or submit a question through their website. Have your Social Security number, filing status, and refund amount ready.
If you filed by mail and your return has not been received after 4 weeks, the state may not have received it yet. Ask the Department of Revenue to confirm receipt. If the return was lost in the mail, you may need to file again or provide a copy of your original return. If you filed electronically and your refund is more than 8 weeks overdue, the state can investigate whether the refund was issued but not received by your bank or postal address.
Refunds issued as checks that are lost or not received
If the Illinois Department of Revenue issued your refund as a check but you never received it, contact the state immediately. The Department of Revenue can verify whether the check was mailed and to what address. If the check was mailed to an old address, you may be able to request a reissue to your current address.
If the check was lost in the mail, the state can issue a replacement check or, in some cases, a direct deposit to your bank account if you provide banking information. Uncashed checks from the Illinois Department of Revenue do not expire, so if you find the original check months later, you can still deposit it. However, if you have already received a replacement, you must return or destroy the original to avoid depositing it twice.
Frequently Asked Questions
Can I get my Illinois refund faster by paying a tax preparation fee?
No. The Illinois Department of Revenue processes all returns at the same speed regardless of whether you used a tax professional or software. Paying for expedited preparation does not speed up state processing. The fastest way to receive your refund is to file electronically and choose direct deposit, which you can do for free through many tax software providers.
What if I filed my Illinois return but the Where's My Refund tool shows no status?
If you filed electronically, the tool may not show your return for 24 to 48 hours after filing. If it has been more than 2 days and the tool still shows nothing, your return may not have been received. Check your filing confirmation email to confirm the return was accepted. If you filed by mail, the state may not have received it yet; wait 3 to 4 weeks before contacting the Department of Revenue.
Do I need to do anything to receive my Illinois refund, or does it come automatically?
Your refund comes automatically once your return is processed and approved. You do not need to take any action unless the state sends you a notice requesting additional information. If you chose direct deposit, the money will be deposited into your bank account. If you chose a mailed check, it will be sent to the address on your return.
What happens to my Illinois refund if I move before it arrives?
If you move after filing but before your refund arrives, contact the Illinois Department of Revenue with your new address. If your refund was already issued as a check to your old address, the post office may forward it to your new address if you filed a change of address form. If the check is returned to the state, you will need to request a reissue to your new address.
Can I split my Illinois refund between multiple bank accounts?
No. The Illinois Department of Revenue allows direct deposit to only one bank account per return. If you want to split your refund, you can receive it in one account and transfer money to another account yourself after it arrives, or you can request a mailed check and deposit it manually into multiple accounts.
