Provide property tax rebate on principal residence based on taxes paid

SB 434 provides a property tax rebate of up to $400 for Montana homeowners who lived in their principal residence for at least 7 months during tax year 2024. It directly affects individual homeowners (not businesses or multiple properties) who paid Montana property taxes on their primary residence, with the rebate amount capped at $400 or the actual taxes paid, whichever is lower. To claim the rebate, homeowners must submit an application electronically (August 15-October 1, 2025) or by mail (postmarked by October 1), including proof of residency and property ownership. The rebate is not subject to Montana income tax, and false claims may result in penalties of 300% of the rebate plus 12% annual interest.
