Establishes a sunset date for county sales taxes imposed for county revenue purposes

HB 2870 requires most county sales taxes used for general revenue to expire 10 years after renewal or adoption, mandating counties to add expiration dates to tax documents and ballot questions. It exempts taxes specifically for jail construction projects, allowing them to last up to 20 years or until related bonds are paid off. The bill applies to all counties (and cities outside counties) imposing such taxes, directly affecting local government revenue planning. The state Department of Revenue will enforce compliance and provide implementation guidance.
