Millage Rate (Mill Rate)
The tax rate used to calculate property taxes, expressed in mills (one-tenth of a cent). One mill equals $1 of tax for every $1,000 of assessed property value. The total millage rate combines rates from all taxing jurisdictions.
Understanding Millage Rate (Mill Rate)
The millage rate is the fundamental mechanism for calculating property taxes. It is set annually by each taxing authority—county, city, school district, special districts—and the rates are combined to determine the total tax burden on a property.
For example, if a property has an assessed value of $200,000 and the combined millage rate is 25 mills, the annual property tax would be $5,000 ($200,000 x 0.025). Different properties in the same area may have different total millage rates depending on which taxing jurisdictions they fall within.
Millage rates are set through a budget process where each taxing authority determines its revenue needs and divides that by the total assessed value of all taxable property in its jurisdiction. This process occurs annually, though most jurisdictions have limits on how much rates can increase year over year.
For tax sale investors, understanding millage rates helps predict future tax obligations and assess the ongoing cost of holding a property. High millage areas mean higher carrying costs but may also indicate more services and potentially higher property values. Low millage areas reduce carrying costs but may reflect fewer services or rural locations.
Millage rates also help investors estimate when currently compliant properties might become delinquent. A sharp millage increase in an area with many fixed-income homeowners could lead to increased delinquencies and more tax sale inventory.
Real-World Example
An investor is evaluating properties in two different counties. County A has a millage rate of 18 mills on a $150,000 assessed value, producing $2,700 in annual taxes. County B has a rate of 32 mills on a $100,000 assessed value, producing $3,200 in annual taxes. The investor factors these carrying costs into their acquisition analysis for each county.
Texas-Specific Information
Texas does not use the term 'millage rate' but the concept is identical. Texas property tax rates are expressed as a rate per $100 of assessed value. For example, a tax rate of $2.50 per $100 equals 25 mills. Texas has some of the highest effective property tax rates in the nation (averaging around 1.6-1.8% of market value) because Texas has no state income tax. The high tax rates contribute to Texas having a relatively large inventory of tax-delinquent properties.
