Idaho Code § 63-3077F
In the case of suspected identity theft involving the use of a social security number or other tax identification number, the state tax commission may disclose to the true owner of a social security number or other tax identification number any tax return or tax return information that identifies the individual using the true owner's stolen social security number or other tax identification number.
A disclosure shall be made only after receipt of a valid written information request from the victim of identity theft and would include only information to allow the victim to identify the individual using the stolen social security number or other tax identification number. Any disclosure to the true owner shall not include financial information on the tax returns or other tax information.
