MODERATE
The bill was renumbered from SB0542.3 to SB 542 and its title was updated to clarify that it provides a property tax rebate specifically for principal residences based on taxes paid in 2024. The core policy changes include defining 'Montana property taxes' to include fees on single-family dwellings, establishing a $400 rebate cap for eligible homeowners, and setting a strict electronic filing window between August 15 and October 1, 2025. The bill also introduces severe penalties, including criminal prosecution and a 300% fine, for filing false or fraudulent rebate claims.
Scope change
The bill's scope remains focused on Montana property tax relief for 2024, but the definition of eligible property was narrowed to exclude entities owning land exceeding one acre, and the rebate is now explicitly limited to owner-occupied principal residences.
