Your Idaho refund ID is a nine-digit number the Idaho State Tax Commission assigns when you file your return

When you file an Idaho tax return, the Tax Commission gives your return a unique identifier called a refund ID. This number appears on your filing confirmation or notice of assessment. You need this ID to track where your refund is in the system and to contact the Tax Commission if something goes wrong.

The refund ID is different from your Social Security number or your case number. It's specific to that tax year and that return. If you filed electronically, you should have received it in a confirmation email. If you filed on paper, it will appear on the notice the Tax Commission sends you after they process your return.

Key Takeaways

  • Your Idaho refund ID is a nine-digit number sent to you by email after e-filing or printed on your notice of assessment after paper filing.
  • You can track your refund status on the Idaho State Tax Commission website using your refund ID, Social Security number, and filing status.
  • Refunds typically take two to four weeks after the Tax Commission receives your return, though this varies by filing method and time of year.
  • If you cannot find your refund ID, you can contact the Tax Commission directly by phone or mail with your Social Security number and tax year.

Where to find your refund ID if you filed electronically

When you file your Idaho return through an e-file provider or the Tax Commission's own online system, you receive a confirmation email immediately after submission. This email contains your refund ID in the subject line or body. Check your email inbox and spam folder for a message from the Idaho State Tax Commission or your tax software provider.

If you cannot find the confirmation email, log back into the website or software where you filed. Most tax software and the Tax Commission's system let you view your filing history and retrieve the confirmation details, including your refund ID. Look for a section labeled "My Returns," "Filing History," or "Confirmation Details."

Where to find your refund ID if you filed by mail

Paper returns take longer to process than electronic returns. After the Tax Commission receives and processes your return—usually four to six weeks after mailing—they send you a notice of assessment. This document shows your refund ID, the amount of your refund, and the expected payment date. The refund ID appears near the top of the notice.

If you filed by mail and have not yet received your notice of assessment, your return may still be in the processing queue. You can contact the Tax Commission to confirm they received it and ask for your refund ID over the phone.

How to track your refund status using your refund ID

Go to the Idaho State Tax Commission website and look for the "Where's My Refund?" tool. This tool is usually located on the homepage under a section for taxpayers or refund information. Click on it and enter three pieces of information: your refund ID, your Social Security number, and your filing status (single, married filing jointly, etc.).

The system will show you the current status of your refund. Common statuses include "Return Received," "Return Being Processed," "Refund Approved," and "Refund Paid." The tool also displays the expected payment date or the date the refund was issued. If your refund was paid by direct deposit, the date shown is when the money left the state's account; it may take one to three business days to appear in your bank account.

What to do if you cannot find your refund ID

Call the Idaho State Tax Commission at 208-334-7660 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Mountain Time). Have your Social Security number, the tax year you're asking about, and your filing method (electronic or paper) ready. The staff can look up your return and provide your refund ID over the phone.

You can also write to the Idaho State Tax Commission, P.O. Box 36, Boise, ID 83722, and include your name, Social Security number, and tax year. Include a self-addressed stamped envelope if you want them to mail the information back to you. Mail responses typically take two to three weeks.

How long Idaho refunds take to arrive

Electronic returns processed without errors typically result in refunds within two to four weeks of filing. Paper returns take longer because they must be manually entered into the system first. A paper return filed in early April may not be processed until late April or early May, and the refund may not arrive until late May or June.

Refunds are issued by direct deposit or check, depending on what you selected when you filed. Direct deposit refunds reach your bank account within one to three business days of the payment date shown in the tracking system. Check refunds are mailed and typically arrive within five to seven business days of the payment date, though mail delivery times vary.

During tax season (February through May), the Tax Commission processes returns more slowly because of volume. If you file in March or April, expect the longer end of the timeline. Returns filed in June or later are usually processed faster.

What to do if your refund is delayed or missing

If the tracking system shows your refund was paid but you have not received it after the expected timeframe, contact your bank first. Ask whether the deposit was received and posted to your account. Sometimes a deposit appears under a different name or account number than expected.

If your bank confirms no deposit was received, or if the tracking system shows no payment date at all, call the Tax Commission. Delays can happen for several reasons: the return is still being processed, there is a discrepancy between your return and IRS records, or the address on file is incorrect. The Tax Commission can tell you which issue applies and what step to take next.

Frequently Asked Questions

Is my refund ID the same as my case number?

No. Your refund ID is assigned to your specific tax return and refund. A case number is used only if the Tax Commission contacts you about a problem with your return. You need your refund ID to track your refund; you only need a case number if the Tax Commission has opened an inquiry.

Can I use the "Where's My Refund?" tool on my phone?

Yes. The Idaho State Tax Commission website is mobile-friendly, and you can use the tracking tool from any device with internet access. You will need your refund ID, Social Security number, and filing status.

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

You have one refund ID for the joint return. Both spouses can use the same ID to track the refund. If you need to contact the Tax Commission, you can provide either spouse's Social Security number along with the refund ID.

How do I know if my refund was sent by direct deposit or check?

Check your original tax return or filing confirmation. You selected the payment method when you filed. The "Where's My Refund?" tool also shows the payment method and the date the refund was issued.

Can I change my refund to direct deposit if I filed by mail and selected a check?

No. Once you file, you cannot change the payment method. If you filed by mail and selected a check, your refund will be mailed. For future years, you can select direct deposit when you file.
