Rate Breakdown

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

How Property Tax Works in Sauk County

Property taxes in Sauk County, Wisconsin, are based on the assessed value of your property and the millage rates (tax rates) set by local taxing authorities. Here’s how the process works:

• Assessment: The Sauk 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 calculated per $1,000 of assessed value. Rates vary by municipality and account for levies from school districts, counties, and other local entities.
• Tax Calculation: Multiply your assessed value by the combined mill rate (divided by 1,000) to estimate your annual tax bill. 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 bill:

• 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 apply for the Wisconsin School Property Tax Credit.
• Disability Exemption: Disabled homeowners may qualify for additional relief under state or county programs.
• Veteran Exemptions: Veterans with service-connected disabilities or unremarried surviving spouses may be eligible for property tax credits.

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

Payment Schedule & Deadlines

Sauk County property taxes are typically due in two installments:

• First Installment: Due January 31 to your local municipal treasurer. This payment is an estimate, often 50% of the prior year’s total tax.
• Second Installment: Due July 31 to the Sauk County Treasurer, reflecting the finalized tax amount after adjustments.

Late Payments: Penalties apply for missed deadlines—typically 1.5% monthly interest. Delinquent taxes may result in a tax lien or foreclosure.

Appealing Your Assessment

If you believe your assessment is inaccurate, follow these steps:

• Review Your Assessment Notice: Check for errors in property details (e.g., square footage, condition).
• Contact the Assessor: Discuss discrepancies informally with the Sauk County Assessor’s Office.
• File a Formal Appeal: Submit a written objection to the Board of Review by the deadline (usually in May). Provide evidence like recent appraisals or comparable sales.

Appeals must be filed within the designated timeframe, and decisions may be further appealed to the Wisconsin Department of Revenue or circuit court.
