Relating to the repeal of or limitations on certain state and local taxes, including school district maintenance and operations ad valorem taxes, the enactment of state and local value added taxes, and related school finance reform; imposing taxes.

HB 77 creates a statewide 6.72% value-added tax (VAT) on business transactions in Texas, replacing certain existing local property taxes for school districts. It directly affects businesses (including small businesses, which are exempt), school districts (through the repeal of some local property taxes), and taxpayers who supply goods or services. The bill calculates tax as the difference between "output tax" (tax on sales) and "input tax" (tax paid on business purchases), with exemptions for governments, nonprofits, and specific services like financial transactions. This tax would fund school finance reforms while modifying how local and state taxes are collected.
