Tax Rate
Late each year county commissioners, city councils, school boards, governing boards of special districts, and other taxing authorities determine the revenue needed and allowed under the law to provide services for the following year.
Each taxing authority calculates a tax rate based on the revenue needed from property tax and the total assessed value of real and personal property located within their boundaries. The tax rate is often expressed as a mill levy.
The tax rates of the various taxing authorities, except schools, providing services in your tax area are added together to form the total local government tax rate.
