How do property taxes work in Texas?
Texas property taxes are assessed annually by local appraisal districts and are calculated as a percentage of your home's fair market value. Because Texas does not collect a state income tax, these property taxes are essential for maintaining the high quality of our local school districts, infrastructure, and public safety departments. Understanding your specific tax rate is a critical component of calculating your monthly mortgage payment.
Components of a Texas Tax Bill
- School Districts (ISD): Usually the largest portion of your bill, funding local education.
- County & City: Covers local government services, parks, and road maintenance.
- MUDs & PIDs: Municipal Utility Districts or Public Improvement Districts often found in newer developments to fund water and sewer infrastructure.
