How it works
Property in Dallas County is taxed based on its taxable assessed value, which generally equals the appraised market value after any applicable exemptions. Multiple local taxing units levy property taxes, including the county, cities, school districts, and special districts. Each entity adopts its own maintenance and operations and interest and sinking rates, which together form a combined local property tax rate applied to the taxable value.
Examples
If a home has a taxable value of 425,000 and the combined local property tax rate is 0.0215, the estimated annual property tax would be 9,137.50. Increasing the rate to 0.023 would raise the estimate accordingly, reflecting the higher overall levy applied to the same taxable value.
Limitations and important notes
The figures shown here represent a non-official estimate derived from user-entered data. Actual property tax bills depend on the specific city, school district, and special districts applicable to a parcel, as well as voter-approved bond rates and any qualifying exemptions or tax ceilings. Official tax bills are issued by the county tax office and may differ from this estimate. Parcel-specific assessments, exemptions, and taxing districts applied by the local assessor in Dallas County, Texas may affect the final property tax amount and are not fully reflected in this estimate.
