Property Tax Calculator: Reappraisal vs. County Budget
See why your tax bill is not just about your property value. Reappraisal changes how the tax burden is distributed. The county budget determines how much total revenue must be collected.
Plain-language takeaway
Many people think a 50% increase in appraised value means a 50% increase in taxes. That is not necessarily true. If the whole county’s assessed value rises, the tax rate should generally adjust downward under a revenue-neutral certified tax rate. Your bill goes up mainly when the county’s required property tax revenue goes up, or when your property value rises faster than the county average.
“Reappraisal changes the size of the pie slices. The county budget decides how big the pie is.”
Visual example: when countywide assessed values rise, the tax rate needed to fund the budget can still move down.

Appraised value is an estimate of market value; taxable amount uses the assessment ratio below.
Assessment ratio: Residential/Farm 25%; Commercial/Industrial 40%; Personal property 30%; Public utility 55%.
Countywide tax base & budget

Where does the property tax rate go?
Your tax bill is not one mysterious number. The total rate is built from separate public funds. This calculator shows how much of your estimated bill goes to general county government, roads/public works, schools, and debt service.
