STATEWIDE TAXPAYER FAQ
MONTANA PROPERTY TAX & EQUALIZATION FAQ
What is the statutory deadline to appeal property taxes in Montana?
The resolved statutory filing deadline for Montana is July 1, 2027 (Form AB-26). Initial local reviews are filed with the County Tax Appeal Board (CTAB), with administrative escalation to the Montana Tax Appeal Board (MTAB).
How is residential property assessed in Montana?
Under Montana law, residential real property is assessed at 1% of fair market value (and commercial property at 1%). Equal and uniform taxation across properties is protected under Mont. Const. art. VIII, § 3 ("The state shall appraise, assess, and equalize the valuation of all property which is to be taxed in the manner provided by law").
How does Truth-in-Taxation work during Montana county reappraisals?
Under Mont. Code Ann. § 15-10-420 (Statutory mill levy calculation formula and cap), when a county completes a reappraisal cycle (Biennial reappraisal cycle for residential property under DOR), the taxing authority must calculate a certified revenue-neutral tax rate so the reappraisal itself does not automatically create an unadvertised windfall tax increase.
