Relating to the calculation of the unused increment rate of a taxing unit.

SB 2541 amends Texas property tax code to change how local taxing units (like cities and counties) calculate their "unused increment rate," which affects how they determine property tax revenue limits. The bill updates the calculation formula to include three years of historical revenue data instead of two, using the previous three tax years' "foregone revenue" amounts divided by current property values. This change applies only to tax years beginning on or after January 1, 2027, with prior years governed by the old rules. The bill directly affects local governments' property tax calculations but does not create new taxes or revenue.
