Rate Breakdown

Property taxes in Kewaunee County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Kewaunee County

Property taxes in Kewaunee County are based on the assessed value of your property and the combined millage (tax) rates set by local governments, including the county, municipalities, school districts, and technical colleges. Here’s how the process works:

• Assessment: The Kewaunee County Assessor’s Office evaluates properties annually to determine their fair market value. Assessments are typically based on recent sales of comparable properties.
• Millage Rates: Tax rates are expressed in mills (1 mill = $1 per $1,000 of assessed value). Each taxing authority sets its own rate, which is then combined to form your total property tax bill.
• Tax Calculation: Your tax bill is calculated by multiplying the assessed value (after exemptions) by the total millage rate.

Available Exemptions

Wisconsin offers several property tax exemptions that may reduce your tax burden:

• Homestead Credit: Low-income homeowners may qualify for a refundable credit based on property taxes or rent paid.
• Senior Citizen Exemption: Residents aged 65+ with limited income may qualify for a reduction in property taxes under the Wisconsin Lottery and Gaming Credit.
• Disability Exemption: Homeowners with disabilities may be eligible for exemptions or deferrals, depending on income and disability status.
• Veteran Exemptions: Veterans with service-connected disabilities or their surviving spouses may qualify for property tax credits or exemptions.

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

Payment Schedule & Deadlines

Kewaunee County property taxes are typically due in two installments:

• First Installment: Due by January 31 to the local municipal treasurer.
• Second Installment: Due by July 31 to the Kewaunee County Treasurer.

Late payments incur penalties of 1.5% per month (or 18% annually). If taxes remain unpaid for an extended period, the county may initiate a tax lien or foreclosure process. Payment plans or deferrals may be available for eligible taxpayers.

Appealing Your Assessment

If you believe your property is over-assessed, you can appeal the valuation:

• Informal Review: Contact the Kewaunee County Assessor’s Office to discuss discrepancies before filing a formal appeal.
• Formal Appeal: File a written objection with the Board of Review by the deadline (typically in May). Provide evidence such as recent appraisals or comparable sales.
• Further Appeals: If unsatisfied with the Board’s decision, you may appeal to the Wisconsin Department of Revenue or circuit court.

Deadlines and procedures are strict, so act promptly. Consult the Kewaunee County Clerk’s Office for current appeal forms and timelines.
