Property taxes fund local government. The bill is the product of an assessed value and a tax rate, and each part can be examined.
The formula
Assessed value (often market value times an assessment ratio) minus exemptions, times the tax rate (mill rate or percentage), equals the tax.
Who sets what
Assessors set values; taxing bodies (counties, cities, schools, districts) set rates by dividing their budgets by the total taxable value.
Assessment vs rate
Owners can challenge their assessed value; rates are set through budgets and politics, not appeals.
Common mistake
Appealing because taxes rose. If the rate rose and the value is fair, an appeal on value will fail.
