A refund ID is a unique number the Idaho Department of Revenue gives you when you file your tax return, and it's the main tool to track where your refund is

When you file a tax return with Idaho, the department assigns a refund ID — a number that belongs only to that return and that refund. You'll see it on your filing confirmation, and you'll need it to check the status of your money at any point after you file. Without it, you can't look up your refund online or by phone.

The refund ID is different from your Social Security number or tax ID. It's specific to this year's return and this particular refund. If you file again next year, you'll get a new refund ID for that return.

Key Takeaways

  • Your refund ID appears on your filing confirmation and is the only way to track your Idaho refund status online or by phone.
  • The ID is unique to each return you file — a new return means a new refund ID.
  • You can check your refund status at any time using the Idaho Department of Revenue's online tool or by calling their refund line.
  • Keep your refund ID in a safe place for the entire tax season, because you'll need it if your refund is delayed or if you have questions.

Where to find your refund ID

If you filed electronically, your refund ID appears on the confirmation screen or email you received immediately after filing. Look for a section labeled "Confirmation Number" or "Refund ID" — it's usually a string of numbers, sometimes with letters.

If you filed a paper return by mail, the Idaho Department of Revenue will send you a notice in the mail that includes your refund ID once they process your return. This can take two to three weeks after they receive it. If you haven't received that notice yet and you filed by mail, wait until you get it before trying to track your refund online.

If you filed through a tax software or a tax preparer, ask them for your confirmation number or refund ID. They should have it on file or be able to pull it from your return.

How to use your refund ID to check status

The Idaho Department of Revenue runs an online refund tracker at tax.idaho.gov. Go to the "Where's My Refund?" tool, enter your refund ID and your Social Security number, and the system will show you the current status of your refund — whether it's been received, is being processed, has been approved, or has been sent out.

You can also call the Idaho Department of Revenue refund hotline at 208-334-7660. Have your refund ID ready when you call. The phone line is open during business hours, and staff can look up your refund status and answer questions about delays or problems.

Check your status as often as you want — there's no limit to how many times you can look it up. Most refunds are processed within 21 days of filing if you filed electronically, or within four to six weeks if you filed by mail.

What the refund status messages mean

When you look up your refund ID, you'll see one of several status messages. "Return received" means Idaho has your return but hasn't started processing it yet. "Return approved" means they've reviewed it, found no problems, and your refund has been authorized. "Refund sent" means the money has left the state's account and is on its way to you.

If you see "Return under review," it means Idaho needs more information or has found something that needs clarification. The notice will tell you what they need. If you see "Return rejected," your return was not accepted and you'll need to file again or contact the department to find out why.

Some refunds show "Refund issued" but the money hasn't arrived yet. This is normal — there's a gap between when the state sends the refund and when your bank receives and deposits it. Direct deposit refunds usually arrive within one to three business days after the status changes to "Refund sent." Paper checks take seven to ten business days.

What to do if you can't find your refund ID

If you filed electronically and didn't save your confirmation email, check your email inbox and spam folder for a message from the tax software you used or from the Idaho Department of Revenue. The subject line usually includes "confirmation" or "refund."

If you filed by mail and haven't received a notice from Idaho yet, wait until you do before contacting the department. Processing paper returns takes longer, and the notice with your refund ID will arrive in the mail.

If you've waited the normal processing time and still don't have your refund ID or a status notice, call the Idaho Department of Revenue at 208-334-7660. Have your Social Security number and the date you filed ready. Staff can look up your return using those details and provide your refund ID or explain why your return hasn't been processed yet.

Refund ID vs. other numbers on your return

Your refund ID is not the same as your confirmation number from your tax software, though they may look similar. Your confirmation number proves you filed; your refund ID is what Idaho assigns to track the refund itself. Some software uses the terms interchangeably, so if you're unsure, use the number from your filing confirmation — it should work with Idaho's tracking tool.

Your refund ID is also different from your Social Security number, your Idaho tax ID, or any other identifier. It exists only for this return and this refund. When you file next year, you'll get a completely different refund ID.

Keep your refund ID safe through tax season

Save your refund ID in a place you can find it quickly — a note in your phone, a file on your computer, or a printed copy with your tax documents. You may need it if your refund is delayed, if you have questions about your return, or if you need to contact Idaho's tax department.

If someone else filed your return for you — a tax preparer, an accountant, or a family member — ask them to give you the refund ID in writing. Don't rely on memory or a verbal promise to look it up later.

Frequently Asked Questions

Can I track my refund without a refund ID?

No. Idaho's online tracker requires your refund ID and Social Security number. If you call the refund line, staff can look up your return using your Social Security number and filing date, but having your refund ID makes it faster.

What if I filed jointly with a spouse — do we get one refund ID or two?

You get one refund ID for the joint return. Both spouses can use that same ID to check the status. The refund itself will go to whichever account or address is listed on the return.

Does my refund ID change if Idaho asks me for more information?

No. Your refund ID stays the same throughout the entire process, even if your return goes under review or needs corrections. Use the same ID to check status and to respond to any notices from Idaho.

How long do I need to keep my refund ID?

Keep it until your refund arrives and you've confirmed the deposit or check cleared. After that, you can discard it, though there's no harm in keeping it with your tax records for the year.

What if the refund ID on my confirmation doesn't match the one on Idaho's notice?

Contact the Idaho Department of Revenue at 208-334-7660. This is unusual, but staff can verify which number is correct and help you track your refund using the right ID.
