Homestead exemption, assessment caps, MUD taxes, and the appeal process.
Texas has one of the highest average property tax rates in the United States at approximately 1.69% of home value. However, Texas also offers one of the most generous homestead exemption programs — $40,000 for school district taxes (2026) — and strict caps on annual assessment increases for homestead properties. Understanding how Texas property tax works can help you budget accurately and identify opportunities to lower your bill.
Texas has no state income tax, which means local governments (school districts, counties, cities, and special districts) rely heavily on property tax to fund public services. Unlike most states, where state income tax provides a large portion of education funding, Texas schools are primarily funded through local property taxes. This structural difference explains why Texas property tax rates are among the highest in the nation.
Texas offers a $40,000 school district homestead exemption for 2026. This means the first $40,000 of your home's assessed value is not taxed by your local school district. Many Texas school districts and counties also offer optional additional exemptions for seniors (age 65+), disabled individuals, and disabled veterans (including 100% disabled veteran exemption from all school taxes).
To qualify, you must:
Once approved, you do NOT need to reapply annually — the exemption automatically renews each year.
For homestead properties in Texas, the assessed value cannot increase by more than 10% per year. This cap applies to the school district portion of your tax bill. However, if you make significant improvements (room addition, major remodel), the improved value can exceed the cap.
This 10% cap is a significant protection for long-time homeowners in rapidly appreciating markets like Austin, Dallas, and Houston. Without the cap, many long-time residents would face tax bills thousands of dollars higher than what they pay today.
The Texas Legislature has considered multiple property tax relief measures in recent sessions, including increasing the homestead exemption (from $25,000 to $40,000 for school taxes), compressing tax rates, and limiting appraisal increases for non-homestead properties. Check the Texas Comptroller's website for the latest enacted changes affecting your 2026 tax bill.
Many Texas residential communities are located within Municipal Utility Districts (MUDs) or other special districts. These districts provide water, sewer, drainage, and road infrastructure — and they levy their own property tax on top of county, city, and school district taxes.
MUD taxes can add 0.2%–0.6% to your effective property tax rate. When buying a home in Texas, always ask whether the property is within a MUD or special district, and request the district's tax rate information.
Texas has a well-defined property tax appeal process. You can protest your assessed value if you believe it exceeds market value or if the appraisal is unequal compared to similar properties. The process:
Many Texas homeowners successfully reduce their assessed value through the protest process. The key is providing strong evidence (recent comparable sales, photos of property defects, etc.). Some Texas homeowners hire professional property tax protest companies that work on a contingency fee basis (you pay nothing unless they lower your assessment).
