Revise government entity limitations on property tax increases

This bill amends Montana's property tax laws to revise how government entities can increase property tax levies. It directly affects state and local taxing units such as school districts, counties, and municipalities that impose property taxes. The key provision allows entities to increase taxes by the prior year's assessed amount plus half of the average inflation rate over the previous three years, capped at 4% total growth. The bill also clarifies how newly taxable property is treated in calculations and establishes specific rules for tax increment financing districts.
