Reminder of personal property reporting requirement

MTDOR recently notified business owners with a personal property reporting requirement that it is time to report for Tax Year 2026 through the department’s TransAction Portal (TAP) at https://tap.dor.mt.gov. Online reporting forms are pre-populated with the business equipment reported in 2025. Owners will review the previously reported equipment and make any needed additions and deletions. An immediate confirmation receipt will be sent after the report is submitted.

Individuals and businesses that own business equipment with a statewide aggregate market value of $1 million or more as of January 1, 2026, must report by February 15, 2026, to avoid a 20 percent penalty.  Entities and individuals new to reporting personal property in Montana can contact the department at DORPPReporting@mt.gov for assistance.

Businesses whose statewide market value of equipment is $1 million or less are exempt from the business equipment tax. These businesses are not required to file a report unless: (1) they have acquired new personal property that may increase their aggregate market value above the exemption threshold; or (2) there are related entities that own personal property in Montana and the combined personal property value is near to or exceeds the exemption threshold; or (3) the department requests a personal property reporting  be completed.
