Rate Breakdown

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

How Property Tax Works in Marathon County

In Marathon County, property taxes 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 Marathon County Assessor's Office evaluates properties annually to determine their fair market value. Assessments are based on factors like property size, location, condition, and comparable sales.
• Millage Rates: Tax rates are expressed in mills (1 mill = $1 per $1,000 of assessed value). Rates vary depending on the municipality, school district, and other local entities like the county and technical college district.
• Tax Calculation: Your tax bill is calculated by multiplying the assessed value (minus exemptions) by the total mill rate. For example, a $200,000 home with a 20-mill rate would owe $4,000 annually.

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 their income and property taxes paid.
• Senior Citizen Exemption: Residents aged 65+ may qualify for a tax credit if their household income falls below state thresholds.
• Disability Exemption: Individuals with disabilities may be eligible for exemptions or credits, depending on income and disability status.
• Veteran Exemptions: Veterans with service-connected disabilities or unremarried surviving spouses may qualify for property tax reductions.

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

Payment Schedule & Deadlines

Marathon County property taxes are typically due in two installments:

• First Installment: Due by January 31st, this payment is an estimated 50% of the prior year's tax bill.
• Second Installment: Due by July 31st, this payment covers the remaining balance based on the finalized tax rate.

Late payments incur a 1.5% monthly interest penalty. If taxes remain unpaid for an extended period, the county may initiate a tax lien or foreclosure process. Payment options include mail, online, or in-person at the Treasurer's Office.

Appealing Your Assessment

If you believe your property assessment is inaccurate, you can appeal through the following steps:

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

Deadlines and requirements are strict, so act promptly if you intend to appeal.
