Bill Overview

Analyzed Economic Effects

3 provisions identified: 1 benefits, 0 costs, 2 mixed.

Property values updated every two years

The Department of Revenue reappraises homes, farms, and other class 3, 4, and 10 property every 2 years. Other property is revalued each year. Centrally assessed property, and any real property valued with it, follows the centrally assessed timeline. By rule, each county’s class 3, 4, and 10 property is revalued by January 1 of the second year, with values effective on January 1 of the next year. The department reviews permits and sales, checks electronic data, and does enough field inspections, using new technology to spot changes.

More tax history in appraisal notices

Each reappraisal notice you get must show the consumer price index adjusted for population and Montana’s average personal income growth. It must also show estimated annualized changes in property taxes over the past 10 years by the state, county, cities or towns, and local school mills. In even-numbered years, the department publishes this in a county newspaper by the second Monday in October. In the second year of each cycle, the department also gives lawmakers a report showing tax-rate changes needed to keep taxable value neutral for each property class.

Changes apply starting 2025 tax year

The law takes effect on passage and approval. It applies to property tax years beginning after December 31, 2024.
