Understanding Mill Levy: Definition and Importance
A mill levy is a property tax rate expressed in mills, where one mill equals one dollar per $1,000 of assessed property value. Local governments and taxing authorities use mill levies to generate revenue for essential public services like schools, parks, and infrastructure.
What Exactly Is a Mill Levy?
The mill levy represents the tax rate applied to the assessed value of your property. It’s calculated by dividing the total revenue required by all taxing jurisdictions within an area by the total assessed value of all taxable properties. The combined rates from entities such as school districts, counties, and cities form the overall mill levy for the region.
Key Points to Remember
- The mill levy is a property tax based on assessed property values.
- One mill corresponds to $1 in tax per $1,000 of assessed value.
- Local authorities use mill levies to fund public services and cover budget needs.
How Mill Levies Operate
Various local taxing bodies independently set their mill rates depending on their budget requirements for the upcoming fiscal year. The final mill levy is the sum of these rates, reflecting the total property tax obligation.
Assessment Ratio and Property Valuation
Most jurisdictions apply an assessment ratio — a percentage used to determine the assessed value of property relative to its market value. This assessed value is the basis for calculating the mill levy. Tax assessors annually set this value, which may sometimes be a fraction of the market price.
Quick Fact
The assessed value used in mill levy calculations is typically set by a tax assessor and may differ from the market value, depending on local rules.
Mill Levy Calculation Example
Imagine the total property value in a region is $1 billion. If the school district requires $100 million, the county $10 million, and the city $50 million, the individual tax levies would be:
- School district: 100 million ÷ 1 billion = 0.10
- County: 10 million ÷ 1 billion = 0.01
- City: 50 million ÷ 1 billion = 0.05
Adding these gives a total mill levy of 0.16, or 160 mills (where 1 mill = 0.001).
Mill levies typically apply to real estate, including land and buildings, as well as significant personal property like vehicles and boats.
How Is the Mill Levy Computed?
The mill levy is calculated by dividing the total revenue needs of all taxing authorities by the total assessed value of taxable properties. The individual rates from each jurisdiction are summed to form the overall mill levy rate.
Application of Mill Levies on Personal Property
Besides real estate, mill levies often apply to personal property such as cars, boats, and other valuable assets, depending on local tax regulations.
Frequency of Mill Levy Adjustments
Mill levy rates can be revised annually or as required to meet budget demands. Adjustments typically undergo public hearings or require approval by local governing bodies before implementation.
Conclusion
The mill levy is a critical component of property tax systems, directly affecting how much homeowners pay for local services. Understanding its calculation and impact helps property owners anticipate tax expenses and navigate local tax policies effectively.
If you have questions about your mill levy or property taxes, consulting a local tax professional or government office is recommended for personalized guidance.
