Mill Rate (Millage Rate)

The property tax rate expressed as dollars per $1,000 of assessed property value. One mill equals $1 of tax per $1,000 of assessed value.

How It Works

For example, a mill rate of 20 means a property assessed at $200,000 would owe $4,000 in property taxes (20 × $200,000 / $1,000). Mill rates vary enormously across cities — from under 5 mills in some Sun Belt cities to over 50 mills in older Northeastern cities. The total mill rate applied to a property may include levies from multiple taxing jurisdictions: city, county, school district, and special districts.
