What Is a Mil in Taxes and How Is It Calculated?

What is a Mil?

A “mil” is a foundational unit in property taxation, primarily used by local governments to calculate property tax liabilities. The term originates from the Latin word “millesimum,” meaning a thousandth, directly reflecting its value. One mil represents one dollar of tax for every one thousand dollars of a property’s assessed value.

How Millage is Calculated

Calculating property tax using a millage rate involves a direct conversion of the property’s assessed value into a tax amount. To determine the tax owed, the property’s assessed value is divided by 1,000, and then this result is multiplied by the established millage rate. For example, a property with an assessed value of $200,000 in a jurisdiction with a 10-mil rate would incur a tax of $2,000 ($200,000 / 1,000 10).

Property taxes are based on an assessed value, which may differ from the property’s market value. Assessed value is often a percentage of the market value, determined by the local tax assessor’s office. This assessed valuation provides the basis for applying the millage rate. The assessed value is periodically updated through revaluations to reflect changes in property values.

How Local Governments Use Mills

Millage rates are established and levied at the local level by various governmental entities to fund public services. Municipalities and counties commonly set millage rates to support general operations, public safety, and infrastructure projects. School districts frequently rely on millage rates as a primary source of funding for educational programs and facilities. Each of these entities can impose its own distinct millage rate.

Special taxing districts also utilize millage rates. These districts fund specific services like fire protection, water management, parks, or libraries. A single property may be subject to multiple millage rates from different local entities, resulting in a cumulative property tax bill. These rates vary from one jurisdiction to another, reflecting differing local needs and service levels.

What Influences Millage Rates

The setting and adjustment of millage rates are primarily driven by the budgetary needs of local governments and special districts. When a local entity requires more revenue to fund schools, public services, or new infrastructure projects, it may consider increasing its millage rate. This ensures that sufficient funds are generated to cover the cost of providing essential community services.

Changes in the total assessed property value within a jurisdiction also significantly influence millage rates. If the overall assessed value of properties within a taxing district increases, the government might be able to collect the same amount of revenue with a lower millage rate. Conversely, a decrease in total assessed value could necessitate a higher millage rate to maintain consistent revenue levels. These two factors work in conjunction to determine the necessary rate to meet financial targets.
