Millage Rates: In simplest terms, most people would refer to this as a tax rate for ad valorem tax purposes. Mils are taxes imposed by each taxing body for a specific purpose. They can be implemented by a vote of the people, allowed legislatively or constitutionally.

For more information regarding millage, you should view the Louisiana Legislative Auditors website.

The Millage Rate is the amount per $1,000 of assessed value used to calculate taxes on property. The Millage Rate is multiplied by the total taxable value of the property to arrive at the property taxes due. For Example: Taxable value 10,000 x .06751 mills = $675.10 of taxes due.
