Residential property-acquisition value.

SF 161 would change how Wyoming taxes residential property by establishing a default rule that a property’s tax assessment should match its purchase price (acquisition value) when it was last bought. This applies directly to residential property owners, as their tax bills would typically be based on the original sale price unless challenged. The bill requires county assessors to use the acquisition date as the starting point for determining fair market value, with a "rebuttable presumption" allowing adjustments only if evidence shows the purchase price was inaccurate. It also clarifies confidentiality rules for sworn statements used in the valuation process. The bill died in committee in March 2025 and was never enacted.
