Rate Breakdown

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

How Property Tax Works in Portage County

Property taxes in Portage 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 Portage County Assessor's Office evaluates your property's market value annually. This assessed value is used to calculate your tax liability.
• Millage Rates: Tax rates are expressed in mills (1 mill = $1 per $1,000 of assessed value). Rates are set by school districts, municipalities, and the county. For example, if your home is assessed at $200,000 and the total mill rate is 20 mills, your annual tax would be $4,000.
• Tax Calculation: Taxes are calculated by multiplying the assessed value (minus exemptions) by the total mill rate.

Available Exemptions

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

• Homestead Credit: Available to low-income homeowners or renters, this credit reduces tax liability based on income and housing costs.
• Senior Citizen Exemption: Homeowners aged 65+ may qualify for a tax credit if their household income falls below state limits.
• 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 their surviving spouses may qualify for property tax reductions.

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

Payment Schedule & Deadlines

Portage 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 current year's assessed value.

Late payments incur penalties of 1.5% per month, and unpaid taxes may result in a tax lien or foreclosure. Payment options include mail, online, or in-person at the Treasurer's Office.

Appealing Your Assessment

If you believe your property's assessed value is inaccurate, you can appeal the assessment in Portage County:

• Step 1: Contact the Assessor's Office to discuss your concerns. Errors may be corrected without a formal appeal.
• Step 2: File a written appeal with the Board of Review by the deadline (typically in May or June). Provide evidence such as recent appraisals or comparable property values.
• Step 3: Attend the Board of Review hearing to present your case. The board may adjust your assessment if justified.

For complex cases, consider consulting a property tax professional or attorney.
