What's included in the Operating Referendum?
The proposed operating referendum would provide approximately $500,000 per year in additional funding to help the School District continue offering essential services. This includes maintaining transportation routes, supporting classroom instruction, and retaining qualified staff. The funding would help the District manage rising costs without reducing services.

How is my estimated tax impact calculated?
The calculator uses your property’s Referendum Market Value (RMV) – which is the portion of your property value subject to the operating referendum – along with the proposed levy amount to estimate your potential tax increase.
Your RMV depends on your property type:
- Residential and commercial properties are taxed on their full RMV.
- Agricultural Homestead properties are taxed only on the value of the house, garage, and one acre.
- Seasonal recreational properties (like cabins) are not taxed under the operating referendums.
The calculator applies the estimated tax rate to your RMV to show how much your annual taxes might increase if the referendum is approved.
Does this estimate include other changes to my taxes?
No, this calculator only shows the estimated impact of the proposed levy. Other factors (like changes in your property’s value) may also affect your final tax bill.
Is this what I’ll actually pay?
This is an estimate based on current information and assumptions. The actual amount you owe is calculated each year using your property’s estimated market value for that specific tax assessment year.
When would these tax impacts take effect?
If approved, the levy would affect property tax bills starting in Pay 2026.
Would I pay for the operating referendum on my agricultural property?
For owners of Agricultural – Homestead property, you will be taxed on the RMV of your house, garage, and one (1) acre of land (commonly referred to as HGA). The Ag2School property tax credit does not apply to this proposed impact.
For owners of Agricultural – Non-Homestead property, your property will not be subject to the proposed increase.
