Rate Breakdown

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

How Property Tax Works in Dane County

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

• Assessment: The Dane County Assessor’s Office evaluates properties annually to determine their fair market value. Assessments are based on recent sales of comparable properties, improvements, and market trends.
• Millage Rates: Tax rates are set by local taxing authorities and applied per $1,000 of assessed value. For example, if your home is valued at $300,000 and the combined mill rate is 20, your annual tax would be $6,000 ($300,000 ÷ 1,000 × 20).
• Tax Bills: Bills are mailed in December and reflect the prior year’s assessment. Payments are due the following January 31.

Available Exemptions

Wisconsin offers several property tax exemptions that may reduce your tax burden. Key exemptions in Dane County include:

• Homestead Credit: Low-income homeowners may qualify for a refundable credit on their income tax return.
• Senior Citizen Exemption: Residents aged 65+ with limited income may qualify for a reduction in property taxes.
• Disability Exemption: Homeowners with disabilities may be eligible for exemptions based on income and disability status.
• Veteran Exemptions: Veterans with service-connected disabilities or unremarried surviving spouses may qualify for partial or full exemptions.

Applications for exemptions must be filed with the Dane County Treasurer’s Office by the specified deadlines, typically in early May.

Payment Schedule & Deadlines

Dane County property taxes are due in full by January 31 of each year. However, payment options are available:

• Installment Plan: Taxpayers may pay in two installments—50% by January 31 and the remaining 50% by July 31—but must enroll by January 31.
• Late Payments: Payments received after the deadline incur a 1.5% monthly interest penalty. Unpaid taxes may result in a tax lien or foreclosure.
• Online Payments: Dane County accepts payments via credit/debit card (with a fee) or e-check through its online portal.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, you can appeal through the following steps:

• Informal Review: Contact the Dane County Assessor’s Office to discuss your assessment. Errors can often be corrected without a formal appeal.
• Formal Appeal: File a written objection with the Board of Review by the deadline (usually in May). Provide evidence such as recent sales data or an independent appraisal.
• Further Appeals: If unsatisfied with the Board’s decision, you may appeal to the Wisconsin Department of Revenue or circuit court.

Deadlines and requirements vary, so check the Dane County website or consult the Assessor’s Office for details.
