Relating to the repeal of ad valorem taxes and certain state and local taxes, the enactment of a uniform state sales tax, and related school and local government finance reform; increasing the rate of a tax.

HB 4648 prohibits most ad valorem (property) taxes in Texas after specific dates: general taxes after January 1, 2026, and school district maintenance/operations taxes after January 1, 2026, while allowing debt service taxes until 2033. It replaces local sales taxes with a uniform state sales tax, amending Chapter 151 of the Tax Code to define "taxable services" like repairs and entertainment. School districts must submit financial reports to the Texas Education Agency and face potential bankruptcy proceedings if they fail to comply with the tax repeal deadlines. This bill directly affects school districts, local governments, and taxpayers by shifting revenue sources from property taxes to a statewide sales tax system.
