How Property Tax Works in Dunn County

In Dunn County, Wisconsin, property taxes are calculated based on the assessed value of your property and the combined millage rates (tax rates) set by local governments. Here's how the process works:

• Assessment: The Dunn County Assessor's Office evaluates your property's market value annually. Assessments aim to reflect fair market value as of January 1 each year.
• Millage Rates: Tax rates are determined by multiplying the assessed value by the mill rate (per $1,000 of value). Rates vary based on jurisdictions, including school districts, municipalities, and the county.
• Tax Calculation: Your tax bill = (Assessed Value × Equalized Value Ratio) × Total Mill Rate. The equalized value ensures fairness across municipalities.

Available Exemptions

Wisconsin offers several property tax exemptions that may reduce your bill. Dunn County residents should check eligibility for the following:

• Homestead Credit: For low-income homeowners, this refundable credit offsets property taxes or rent.
• Senior Citizen Exemption: Residents aged 65+ may qualify for a tax credit if income falls below state thresholds.
• Disability Exemption: Homeowners with disabilities may receive reductions based on income and disability status.
• Veteran Exemptions: Veterans with service-connected disabilities or wartime service may qualify for partial exemptions. Surviving spouses may also be eligible.

Applications for exemptions must be filed with the Dunn County Treasurer’s Office by specified deadlines.

Payment Schedule & Deadlines

Dunn County property taxes are typically due in two installments:

• First Installment: Due January 31 to your local municipality. This payment is an estimate (usually 50% of the prior year’s tax).
• Second Installment: Due July 31 to Dunn County, adjusted for the final tax amount.

Late payments incur penalties:

• 1% monthly interest on unpaid balances after the deadline.
• Potential tax lien or foreclosure for prolonged non-payment.

Payment options include mail, online, or in-person at the Treasurer’s Office.

Appealing Your Assessment

If you believe your property is overassessed, follow Dunn County’s appeal process:

• Step 1: Contact the Dunn County Assessor’s Office to discuss your valuation. Errors may be corrected without formal appeal.
• Step 2: File a written objection with the Board of Review by the deadline (typically mid-April). Provide evidence (e.g., recent sales of comparable properties).
• Step 3: Attend the Board of Review hearing to present your case. If unsatisfied, you may appeal to the Wisconsin Department of Revenue or circuit court.

Deadlines and forms are available on the Dunn County website. Acting promptly is critical, as appeals are time-sensitive.
