Property Tax Calculator

The formula to calculate real property tax is: Assessment x millage = tax (face amount). The County Tax for a property with an assessed value of $100,000 and a rate of 4.163 mills would be calculated as follows:

100,000 X .004163 = $416.30 (face amount)

Note: 4.163 mills is equivalent to a millage of .004163. This is comparable to expressing percentage as whole number (5%) and as a decimal (.05). In the case of millage, the decimal is moved three places to left instead of two.
