How the tax is worked out
The bill is built in stages. First the assessor puts a market value on the property. Exemptions — a homestead exemption above all — then reduce the taxable amount. Finally the combined local rate is applied. To see the scale: at the county's derived rate of 0.77%, each $100,000 of value corresponds to about $765 of tax a year, and a $400,000 home to roughly $3,060. Real bills use the official assessment and district rates, not this derived figure, so treat the example as a sense of scale only.
