SB 2415 amends the Texas Tax Code to require that additional property tax information related to school district funding be made available on county websites and included on tax bills or separate statements. For school districts receiving "excess revenue," or more than their entitlement as specified by the Texas Education Code, the county website must show the percentage of local maintenance and operations (M&O) taxes used to purchase attendance credits and the percentage retained by the district. For other districts, the county must post the percentage of M&O revenue derived from local taxes versus state funds for the current and previous years. These details must also be referenced in the tax bill.
