On November 22, 2023, the Montana Supreme Court ruled that all county governments must collect the 95-mill state school equalization levy for Tax Year 2023 property tax collections, rather than the 77.9 mils previously billed by 49 of the state's 56 counties.
Your county may be sending you a revised property tax bill that complies with Montana law. Please note that it is the function of the county treasurers to collect property taxes, not the state government.
For additional questions on the supplemental tax bills, please contact your county treasurer’s office or your county commissioners.
Understanding Your Property Appraisal Notice
Property classification and appraisal notices for tax years 2023-2024 were mailed to property owners in June 2023.
Property owners had until June 1, 2024 to submit a Request for Informal Classification and Appraisal Review (Form AB-26) on the property values provided in their 2023 appraisal notice.
If you missed the June 1, 2024 deadline, your next opportunity to submit a request for informal review will be in 2025 after you receive your appraisal notice for the 2025-2026 valuation cycle.
Some property owners will receive a new property classification and appraisal notice in the spring of 2024 if one or more of the following changes pertaining to their property occurred within the past year:
- an ownership change
- a classification change
- a valuation change
- an addition or subtraction of personal property affixed to the land
For property where none of the changes referenced above occurred, the property taxable value included in the notice mailed in 2023 will be used by local county governments to determine property taxes owed for tax year 2024.
Property owners receiving a notice in 2024 have 30 days from the date on their notice to submit a Request for Informal Classification and Appraisal Review (Form AB-26). If the department determines valuation adjustments are warranted for the property, the adjustments will apply only to Tax Year 2024. If you miss the 30-day deadline, your next opportunity to submit a request for informal review will be in 2025 after you receive your appraisal notice for the 2025-2026 valuation cycle.
