Relating to the repeal of provisions providing for the calculation of an unused increment rate and the use of that rate in calculating certain other ad valorem tax rates.

HB 176 repeals specific provisions in Texas tax law related to property tax calculations. It removes the "unused increment rate" from formulas used to determine voter-approval tax rates for most local taxing units (excluding special taxing units). This change simplifies how local governments calculate the tax rate needed for voter approval when property values change or new taxes are imposed. The bill directly affects county and city governments that levy property taxes and must follow these tax rate calculation rules. The key change is eliminating a specific calculation component ("unused increment rate") from the existing formulas.
