Taxation must be equal and uniform. This means that appraisers must value similar properties in the same way, and taxing units must tax in a uniform manner. No single property or type of property should pay more than its fair share of taxes. The next three principles also assure equal and uniform taxation. Property must be taxed on the basis of its market value unless the property qualifies for special-use appraisal.
All property is taxable unless federal law or the state constitution provides an exemption for it.
Appraisers may not appraise property above its market value. All property within a county must receive a single appraisal for property tax purposes. There must be a single Appraisal Review Board for each appraisal district. In order to understand how the Texas property tax system functions, you need to be able to identify the political subdivisions, public officials, and governmental agencies that administer the system. We will describe specific roles and responsibilities of these entities throughout the text.
