The Texas property tax estimator projects your annual property tax bill from a home’s appraised value, your local combined rate, and the homestead exemption. Texas has no state property tax — every dollar is levied by overlapping local taxing units — and effective rates are among the highest in the country, so an accurate estimate matters for budgeting and home shopping.
How it works
Texas appraises property at 100% of market value. The taxable value is
market value − homestead exemption, and the tax is taxable value × combined local rate. With a $350,000 home, the $100,000 school-district homestead exemption
leaves $250,000 taxable; at a combined rate of 1.80% that is
$250,000 × 0.018 = $4,500 per year, or about $375 per month in escrow. The tool
also reports your effective rate — tax as a percentage of full market value — which
falls below the nominal rate once the exemption is applied.
Tips and notes
The single combined rate blends your county, city, school district, and special districts, and the school portion is usually the largest. For the closest result, enter the exact combined rate printed on your appraisal district notice rather than the statewide average. Homeowners who are 65 or older or disabled qualify for additional exemptions and a school-tax ceiling, and a homestead’s taxable value increase is capped at 10% per year. Confirm current exemptions and rates at comptroller.texas.gov and your county appraisal district.
