Illinois tax refunds typically arrive within 30 to 60 days from the date the Illinois Department of Revenue receives your return
The timeline depends on how you file and whether the Department of Revenue needs to review your return. If you file electronically and request direct deposit, you are most likely to receive your refund within 30 days. If you file by mail or request a paper check, the process takes longer — usually 60 days or more from the date your return arrives at the Department of Revenue office in Springfield.
The Department of Revenue does not begin processing returns until they are received and scanned into their system. Mail takes several days to reach Springfield, which means your 60-day clock does not start on the day you mail the return — it starts when the Department opens and processes it. If your return requires manual review because of errors, missing information, or a mismatch between your filing and your W-2s or 1099s, the refund will take longer.
Key Takeaways
- Electronic filing with direct deposit is the fastest method, typically resulting in a refund within 30 days of the Department of Revenue receiving your return.
- Paper returns filed by mail take 60 days or longer because mail delivery time is not included in the processing window.
- The Department of Revenue's processing clock starts when your return is received and scanned, not when you mail it or file it electronically.
- Returns that contain errors, missing information, or discrepancies with W-2s and 1099s will be delayed while the Department reviews them.
- You can track your refund status through the Illinois Department of Revenue website using your Social Security number and refund amount.
How to track your Illinois refund status
The Illinois Department of Revenue offers a refund tracking tool on its website at tax.illinois.gov. Go to the "Where's My Refund?" section and enter your Social Security number, filing status, and the exact refund amount from your return. The tool will show you whether your return has been received, is being processed, or has been approved for payment.
The tracking tool updates once per day, usually overnight. If you filed electronically, you can begin checking the day after you receive your e-file confirmation. If you filed by mail, wait at least two weeks before checking, since mail delivery and initial scanning take time. The tool will tell you the expected payment date once your return has been approved.
If the tracking tool shows no record of your return after three weeks (for electronic filers) or four weeks (for mail filers), contact the Illinois Department of Revenue at 217-782-3336 to confirm they received it. Have your Social Security number, filing status, and the date you filed ready.
Why some refunds take longer than 60 days
The Department of Revenue flags returns for manual review when they spot inconsistencies or missing information. Common reasons include a mismatch between the income you reported and the W-2s or 1099s your employer or financial institution sent to the state, missing schedules or forms, math errors, or claims for credits the Department needs to verify.
If your return requires review, the Department will mail you a letter explaining what they need. You must respond within 30 days of the letter's date. Once the Department receives your response and verifies the information, they will process your refund. This can add 30 to 90 days to the total timeline, depending on how quickly you respond and how long verification takes.
Returns filed close to the April 15 deadline also experience delays because the Department receives a high volume all at once. Filing early — in February or early March — reduces your wait time because the Department processes returns in the order they are received.
Direct deposit versus paper check delivery
Direct deposit is faster and more reliable than a paper check. If you request direct deposit on your return, the Department of Revenue will deposit your refund directly into your bank account once it is approved. This usually takes 30 days from the date your return is received. The deposit appears in your account within one to two business days after the Department initiates the transfer.
A paper check takes longer because the Department must print it, mail it, and it must travel through the postal system to reach you. Even after the Department approves your refund, you are waiting for printing and mail delivery — typically an additional 7 to 14 days. If the check is lost or delayed in the mail, you will need to contact the Department to request a replacement, which adds more time.
If you did not provide banking information on your return and did not request direct deposit, the Department will mail a check. You can update your banking information by calling the Department at 217-782-3336 before your refund is approved, and they may be able to switch your refund to direct deposit.
What to do if your refund is late
If your refund has not arrived within the expected timeframe, first check the "Where's My Refund?" tool again to see if the status has changed. If the tool shows your refund was approved and sent, but you have not received it after the expected delivery date, contact the Illinois Department of Revenue at 217-782-3336.
Have your Social Security number, filing status, refund amount, and the date the tool showed your refund was approved. The Department can tell you whether the refund was sent by direct deposit or check, and if it was sent by check, they can investigate whether it was lost in the mail. If the check was lost, the Department can issue a replacement.
If the tracking tool shows your return is still being processed after 90 days, or if you received a letter from the Department requesting additional information and you have already responded, call 217-782-3336 to speak with a representative. Bring documentation of your response to the Department's letter.
Amended returns and refund delays
If you filed an amended return (Form IL-1040-X) to correct an error on your original return, the refund timeline resets. The Department processes amended returns separately from original returns, and they typically take 60 to 90 days to process. You cannot track an amended return through the "Where's My Refund?" tool — you must call the Department at 217-782-3336 to check the status.
Do not file an amended return unless you made an error on your original return. Filing an amended return when your original return was correct will only delay your refund. If you realize you made a mistake after filing, wait until the Department contacts you about it rather than filing an amended return on your own.
Frequently Asked Questions
Can I get my Illinois refund faster if I pay a fee?
No. The Illinois Department of Revenue does not offer expedited processing for any fee. The timeline is the same for all filers — 30 days for direct deposit or 60 days for paper checks, assuming no issues with your return. Any service claiming to speed up your refund for a fee is not affiliated with the state.
What if I filed my return electronically but the tracking tool shows nothing?
Wait at least one business day after you receive your e-file confirmation before checking the tool. The Department's system updates once per day. If the tool still shows no record after three days, contact the Department at 217-782-3336 to confirm they received your return and have your e-file confirmation number ready.
Will my refund be delayed if I owe back taxes or child support?
Yes. If you owe back taxes to Illinois or federal taxes, or if you owe child support, the Department of Revenue will offset your refund to pay those debts before sending you the remainder. This process adds 30 to 60 days. You will receive a notice explaining the offset.
Can I request my refund as a check instead of direct deposit after I file?
No. Once you file your return, you cannot change the refund method. If you requested direct deposit, your refund will be deposited. If you did not provide banking information, a check will be mailed. You can only change the method before you file by updating your banking information on the return itself.
What happens if the Department of Revenue finds an error on my return?
The Department will mail you a letter explaining the error and what they found. You have 30 days to respond with documentation or corrections. Once they receive your response, they will review it and either approve your refund or request more information. This process typically adds 30 to 60 days to your refund timeline.
