How it works
Property in Houston is appraised at market value by the county appraisal district. In general, property is valued at 100% of market value. Local taxing units, including the city, county, school district, and other districts, each adopt their own tax rate. The estimated property tax is calculated by applying a combined local property tax rate to the taxable value. Exemptions may reduce taxable value if the owner qualifies and applies.
Examples
For example, if a property has a market value of 300,000 and the combined local property tax rate is entered as a single percentage, the estimated property tax is calculated by multiplying the taxable value by that combined rate. The actual combined rate depends on the specific taxing jurisdictions that apply to the property.
Limitations and important notes
This calculator provides an estimated property tax only. Houston property tax rates vary by taxing jurisdiction and property location. Exemptions depend on eligibility and timely application. The actual tax bill may differ based on district-specific rates and official calculations by the relevant authorities.
