How it works
Property taxes in Galveston County are estimated using the assessed value determined by the county appraisal district under Texas law. A combined local property tax rate is then applied, representing the total of all taxing units that apply to the property’s location.
Examples
Properties located in different taxing districts within the county may produce different estimated tax amounts even if their assessed values are identical. This is due to variation in overlapping local levies.
Limitations and important notes
This estimator provides a simplified calculation based on the value and rate entered. Actual property tax bills can differ due to exemptions, homestead value limits, voter-approved rate changes, boundary differences between taxing units, or reassessments by the appraisal district.
