How Union County compares
Think your bill is too high?
Divide your yearly tax by your home's market value. If your result is well above what neighbors with similar homes pay, your assessed value may be too high or an exemption may be missing.
- Check the market value on your notice against recent sales nearby.
- Make sure every exemption you qualify for is listed, starting with the homestead exemption.
- File an appeal before the deadline. Filing is usually free or costs little.

Your Union County tax offices
Two local offices handle property tax. The assessor (or appraisal district) sets your home's taxable value and handles exemptions and appeals. The treasurer or tax collector sends the bill and takes payment. Both are usually listed under the county's departments.
Before paying online, check that you are on the county's own site. Private sites sometimes charge extra fees for the same payment.
