Check your return status through the Illinois Department of Revenue website

The Illinois Department of Revenue runs a tool called Where's My Return? that shows you exactly where your state tax return stands. You can access it on the department's website without logging in — you only need your Social Security number and the amount you expect to receive or owe.

The tool tells you whether your return has been received, is being processed, has been approved, or has been sent to the state comptroller's office for payment. If there's a problem — missing documents, math errors, or a mismatch between what you reported and what employers reported — the tool will flag it and tell you what to do next.

Processing times vary depending on the time of year and how complex your return is. straightforward returns filed early in the season typically process in two to three weeks. Returns filed closer to the April important date or those requiring additional review can take longer.

Key Takeaways

  • The Illinois Department of Revenue's Where's My Return? tool is the official source for your return status and requires only your Social Security number.
  • If your return shows a problem, the tool explains what documents or information the department needs from you and how to send it.
  • Direct deposit refunds typically arrive within one to two weeks after approval; paper checks take longer.
  • If you filed electronically and your return was accepted, you can track it from the moment it arrives at the department.

What the status messages mean

Return received means the department has your return but hasn't started reviewing it yet. This is normal and doesn't mean anything is wrong. Returns sit in this status for a few days to a few weeks depending on volume.

Return approved means the department has reviewed your return, found no problems, and calculated your refund or balance due. If you chose direct deposit, your refund will be transferred to your bank account within one to two weeks. If you requested a paper check, allow three to four weeks from the approval date.

Return under review or additional information needed means the department found something that doesn't match — perhaps a discrepancy between what you reported and what your employer reported on a W-2, or a missing form. The tool will specify what's needed. You'll also receive a letter in the mail with the same information.

How to respond if the department needs more information

When the Where's My Return? tool shows that additional information is needed, you have two options: mail the documents to the address shown in the letter you receive, or upload them through the department's website if that option is available for your specific issue.

Keep copies of everything you send. Include a cover letter with your name, Social Security number, and the tax year in question. Mail documents to the Illinois Department of Revenue at the address listed on the letter — do not send them to a local office, as they will be rerouted and processing will be delayed.

Once the department receives your documents, processing typically takes another two to four weeks. You can check the Where's My Return? tool again after a week to see if your documents have been received and processed.

If your return shows an error or rejection

If the Where's My Return? tool shows that your return was rejected — meaning it was not accepted for processing at all — the tool will explain why. Common reasons include a missing signature, a math error, or a mismatch in your Social Security number or filing status.

You'll need to file an amended return or a corrected return, depending on what went wrong. The letter you receive will specify which form to use. For most errors, you'll file Form IL-1040-X (Amended Illinois Individual Income Tax Return) or resubmit Form IL-1040 with corrections.

If you filed electronically and your return was rejected, you can correct it and refile electronically. If you filed on paper, you can either file a corrected paper return or switch to electronic filing for the correction.

Tracking a refund after approval

Once your return is approved, the Where's My Return? tool will show the refund amount and the expected payment date. If you chose direct deposit, your bank will receive the funds on or shortly after that date. Your bank may take an additional day or two to post the deposit to your account.

If you requested a paper check, the comptroller's office (which handles all state payments) will mail it to the address on your return. Paper checks typically arrive within three to four weeks of the approval date, though mail delivery times vary.

If your refund doesn't arrive by the date shown in the tool, wait a few more days — delays happen. If it's more than a week late, contact the Illinois Department of Revenue to confirm the payment was sent.

What to do if you can't find your return in the system

If you filed your return but the Where's My Return? tool shows no record of it, the return may not have been received yet. If you filed electronically, check your email for a confirmation message from the tax software or the department — this confirms the return was transmitted. If you filed on paper, allow at least two weeks for it to arrive and be entered into the system.

If more than two weeks have passed since you filed electronically and the tool still shows nothing, contact the Illinois Department of Revenue directly. Have your Social Security number, filing status, and the date you filed ready. If you filed on paper and more than three weeks have passed, the department can search for your return by mail date and amount.

If your return was lost in the mail, you'll need to file again. Keep a copy of the original return you filed so you can verify the information if the department finds the first one later.

Contact information and next steps

The Illinois Department of Revenue's main phone line is 217-782-3336. You can also reach them through their website, which has a contact form for specific questions. Response times for email inquiries vary, so calling is faster if you need an when ready answer.

If you're working with a tax professional or accountant, they can also contact the department on your behalf — you'll need to authorize them in writing first. Many tax professionals have direct lines to the department and can get answers faster than individual callers.

Keep all letters from the Illinois Department of Revenue, as they contain important information about what's needed and important date for responding. If the department requests documents by a certain date, meet that important date — missing it can delay your refund or result in penalties.

Frequently Asked Questions

How long does it take to get a refund after my return is approved?

Direct deposit refunds arrive within one to two weeks of approval. Paper checks take three to four weeks from approval. The Where's My Return? tool shows the expected payment date once your return is approved.

What if the Where's My Return? tool says my return is still being processed after 6 weeks?

Returns that require additional review or have discrepancies can take longer. Check the tool to see if additional information is needed. If the tool shows no message and it's been more than six weeks, contact the Illinois Department of Revenue to ask about the delay.

Can I amend my return after I've filed it?

Yes. File Form IL-1040-X (Amended Illinois Individual Income Tax Return) to correct errors or report income you missed. You can file an amended return at any time, but filing sooner is better — the department can process it faster if your original return hasn't been approved yet.

What happens if I filed electronically but didn't get a confirmation email?

Check your spam folder first. If you still can't find it, log into the tax software you used and look for a confirmation number or receipt. You can also use the Where's My Return? tool — if your return appears there, it was received successfully.

Do I need to call the department if my return shows "under review"?

Not when ready. Wait for the letter from the department, which will explain what information is needed and how to send it. If you don't receive a letter within two weeks of seeing "under review" in the tool, then call to confirm what's needed.
