Identity Verification

Why this is necessary

In order to prevent identity theft and cybercrime, we have implemented an identity protection verification process to reduce the chances of someone fraudulently filing a tax return using your name and stealing your refund.

Why you were chosen

Our system is designed to notice the possibility of identity fraud. When this happens, we require the taxpayer to prove their identity before processing the refund.

How the process works

If your return is chosen, we will send you an Identity Protection Verification letter that asks you to complete a verification process. Depending on the situation, this letter may ask you to take a short online quiz or to provide documents to verify your identity.

Important: You will not receive your refund until you have successfully completed the Identity Verification process.

Who can complete this process

  • Only those taxpayers who are sent an ID Protection Verification letter can complete the process.
  • The taxpayer who received the letter must complete the process themselves or have a legal guardian or Power of Attorney assist.

What to do if you have a physical or language barrier

Call the Taxpayer Services Division at 801-297-2200 or 800-662-4335, Monday through Friday from 8:00 a.m. to 5:00 p.m.

Identity Verification Quiz

If you are selected for the identity verification process, your notification letter may provide you the option of verifying your identity by taking an online quiz. You must correctly answer five multiple choice questions with answers that help us verify your identity. The letter will direct you to take the quiz on our secure website at

Identity verification questions are based on information from your driver’s license or state ID card, and your Utah income tax returns for the previous one or two years (if you had Utah tax returns for those years). Have these documents on hand before beginning the quiz. You will know immediately if the process was successful, and if so, we will process your refund.

If you are unable to complete the quiz online by the due date, or if you are not successful in passing the quiz, you must send documents to us that prove your identity. Instructions for sending the documents to us are provided in the letter.

Sending Identity Verification Documents

If you are selected for the identity verification process, you can complete the process by sending the requested documents to the Tax Commission. The documents may be uploaded or mailed.

If you receive a letter that requires you to send identity verification documents to a website or address that does not match those listed below, it’s possible that letter is fraudulent. Please send a copy of that letter and the documents required to the website or address below rather than the one listed on that letter.
