Rate Breakdown

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

How Property Tax Works in Fond Du Lac County

Property taxes in Fond Du Lac County are calculated based on the assessed value of your property and the combined millage rates (tax rates) set by local taxing authorities. Here's how the process works:

• Assessment: The County Assessor's Office determines the fair market value of your property as of January 1 each year. This assessment is used to calculate your tax liability.
• Millage Rates: Tax rates are set by school districts, municipalities, and the county. These rates are applied per $1,000 of assessed value. For example, if your home is valued at $200,000 and the combined mill rate is 20, your annual tax would be $4,000.
• Tax Bills: Bills are typically mailed in December and are due by January 31 of the following year.

Available Exemptions

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

• Homestead Credit: A refundable credit for low-income homeowners, renters, and qualifying seniors.
• Senior Citizen Exemption: Residents aged 65+ may qualify for reduced property taxes based on income limits.
• Disability Exemption: Homeowners with disabilities may be eligible for tax relief under certain conditions.
• Veteran Exemptions: Veterans with service-connected disabilities or surviving spouses may qualify for partial or full exemptions.

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

Payment Schedule & Deadlines

Fond Du Lac County property taxes follow a strict payment schedule:

• Full Payment Deadline: Taxes are due in full by January 31. Payments made after this date incur a 1.5% monthly penalty.
• Installment Option: Eligible taxpayers may pay in two installments—50% by January 31 and the remaining 50% by July 31.
• Late Payments: Delinquent taxes may result in a tax lien or eventual foreclosure if unpaid for an extended period.

Payments can be made online, by mail, or in person at the County Treasurer’s Office.

Appealing Your Assessment

If you believe your property assessment is inaccurate, you have the right to appeal:

• Informal Review: Contact the 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 property assessments.
• Further Appeals: If unsatisfied with the Board’s decision, you may appeal to the Wisconsin Department of Revenue or circuit court.
