Provide two-year reappraisal cycle for all real property
HB 90 changes Montana's property tax assessment process by requiring all real property to be reappraised every two years instead of annually, effective immediately and applying retroactively to tax years beginning after December 31, 2024. This applies to every property owner across Montana, as the bill modifies the state code to mandate biennial reappraisals for all real property, not just specific classes. The law does not alter tax rates or calculation methods but adjusts the timing for reassessing property values. Property owners will receive updated reappraisal notices with comparative data on local tax trends, as required by the bill. The change streamlines the assessment schedule while ensuring tax neutrality through departmental reporting.

MINOR
The bill text shows minor formatting adjustments and the removal of a duplicate closing marker, but no substantive policy changes were made to the legislation itself. The core provisions regarding the two-year property reappraisal cycle and the specific tax years affected remain exactly the same.
TECHNICAL
Removed a duplicate '- END -' closing marker that appeared twice in the document.
Adjusted the spacing and alignment of the bill title and sponsor information for consistency.
