Rate Breakdown

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

How Property Tax Works in Vernon County

Property taxes in Vernon County are 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 Vernon County Assessor's Office evaluates properties annually to determine their fair market value as of January 1. Assessments must reflect 100% of the property's value under Wisconsin law.
• 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 assessed at $200,000 and the combined mill rate is 20, your annual tax would be $4,000.
• Tax Calculation: Taxes = (Assessed Value × Mill Rate) / 1,000. Adjustments may apply for exemptions or credits.

Available Exemptions

Vernon County offers several exemptions that can reduce your property tax burden:

• Homestead Exemption: Available to Wisconsin residents who own and occupy their primary home as of January 1. This may lower the taxable value of your property.
• Senior Citizen Exemption: Residents aged 65+ with income below $24,680 (2023 limit) may qualify for a tax credit under the Wisconsin Lottery and Gaming Credit program.
• Disability Exemption: Disabled homeowners may be eligible for additional deductions or credits, depending on income and disability status.
• Veteran Exemptions: Veterans with service-connected disabilities or unremarried surviving spouses may qualify for property tax relief under state programs.

Applications for exemptions must be filed with the Vernon County Treasurer's Office by the deadline, typically in early May.

Payment Schedule & Deadlines

Vernon County property taxes are due annually, with the following key dates:

• Tax Bills Mailed: By mid-December each year.
• Full Payment Deadline: January 31. Payments postmarked after this date incur penalties.
• Installment Option: Taxpayers may pay in two installments (January 31 and July 31) if the total tax exceeds $100.
• Late Payments: A 1.5% monthly penalty (up to 18% annually) applies to overdue taxes. Delinquent accounts may face tax lien or foreclosure proceedings.

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

Appealing Your Assessment

If you believe your property is overassessed, you can appeal the valuation:

• Step 1: Informal Review – Contact the Vernon County Assessor's Office to discuss your assessment. Errors can often be corrected without a formal appeal.
• Step 2: Formal Appeal – File a written objection with the Board of Review by the deadline (usually in May). Provide evidence such as recent sales of comparable properties or an independent appraisal.
• Step 3: Further Appeals – If unsatisfied, you may appeal to the Wisconsin Department of Revenue or circuit court within 90 days of the Board of Review's decision.

Deadlines are strict, so act promptly after receiving your assessment notice.
