The standard formula is:

Property Tax=Assessed Value×Tax Rate\text{Property Tax} = \text{Assessed Value} \times \text{Tax Rate}Property Tax=Assessed Value×Tax Rate

Some counties use mill rates:

Property Tax=Assessed Value×Mill Rate1000\text{Property Tax} = \frac{\text{Assessed Value} \times \text{Mill Rate}}{1000}Property Tax=1000Assessed Value×Mill Rate​
