Property tax: Headlee; calculation of Headlee rollback; modify. Amends sec. 34d of 1893 PA 206 (MCL 211.34d). TIE BAR WITH: HB 5996'26

This bill modifies how Michigan calculates property tax increases under the Headlee Amendment for taxes levied after 2026. It clarifies that increases in taxable value resulting from a transfer of ownership must be included when determining the millage reduction fraction, which limits how much a local government's tax rate can rise. The change directly affects property owners and local tax authorities by altering the formula used to compute allowable tax rate increases. This amendment ensures that property value jumps due to sales are factored into the state's property tax cap calculations.
