The Montana Department of Revenue may send a taxpayer a letter by U.S. Mail to confirm that person’s identity. This letter will ask the taxpayer to send copies of identifying documents to the department to confirm the identity of the person filing a tax return.

Many taxpayers are concerned that these letters are scams, trying to steal personally identifying information from taxpayers.

While it is important that Montanans stay vigilant against scams and frauds, they should be also aware that this Identity Verification letter is a legitimate request from the Montana Department of Revenue. Taxpayers receiving this letter should respond as soon as possible with the requested materials to avoid any delay in receiving their refund.
