Each year in late September or early October, the county assessor places the taxes certified by the taxing districts on the tax roll. Property taxes are placed on the tax roll in the form of a rate per $1,000 of assessed value. Just to inform you, the assessed value and the market value of a property are not the same. Assessed value is assigned by the tax assessor for the purpose of taxation. Market value is assessed by the buying public. When a district certifies a dollar amount tax levy, the assessor will then calculate the tax rate. So then,
to calculate a property tax rate in a specific location you'll need to know the following:
tax levy amount and the taxable assessed value.
Here is the equation tax levy amount/taxable assessed value = tax rate
