Montana Form AB-30T is the state’s application a tribe uses to request a temporary property tax exemption for the current year on qualifying fee land that the tribe is working to place into federal trust title. The key idea is timing and proof: the state requires the tribe to apply by the annual deadline and to include specific documents showing the trust process is underway (for example, confirmation that the tribe’s trust request package is complete, a tribal resolution identifying the land by legal description, and ownership/transfer documentation). This application starts a formal review by the Montana Department of Revenue, which then issues a written decision (approved or denied) and notifies local offices. If approved, it does not “run forever” without action—there is an annual certification requirement, and there are recapture rules if the trust request is denied or the property does not enter trust within the temporary exemption timeframe. In short, AB-30T is the paperwork pathway for tribes seeking a temporary Montana property tax exemption while a Bureau of Indian Affairs trust application is still being considered.
