How Property Tax Works

Washburn County, Wisconsin operates under the state's property tax system, which serves as the primary funding mechanism for local government services, schools, and special districts. The county's property tax levy for 2025 is projected at $12,613,000, representing an estimated 4.3% increase compared to 2024. Wisconsin's base property tax rate averages around 1% of assessed value, though actual rates in Washburn County vary significantly depending on your specific location within the county.

Property tax rates differ across Washburn County due to various taxing jurisdictions including school districts, municipalities, technical colleges, and special districts such as lake management or fire protection districts. Each property owner's total tax rate represents the combined levy from all applicable taxing authorities that serve their specific location. The county treasurer administers property tax collection through a two-installment payment system, with most current tax roll items transferred to the County Treasurer for collection beginning in February.

Supplemental Tax Bills

Supplemental taxes in Washburn County are additional property tax assessments that occur when there are changes to property ownership, new construction, or improvements completed after the annual assessment date. These taxes are calculated based on the difference between the old and new assessed values, prorated for the portion of the tax year remaining after the change occurs.

Common triggers for supplemental taxes include purchasing property that was previously exempt, completing new construction or major renovations, and changes in property use that affect its taxable status. For example, if you complete a $50,000 home addition in June and your total tax rate is 2.0%, you would owe approximately $500 in supplemental taxes ([$50,000 × 2.0%] × 50% for half the tax year remaining). Supplemental tax bills are issued separately from regular property tax bills and have their own payment deadlines.

Escrow & Property Taxes

Most mortgage lenders in Washburn County require property tax escrow accounts for borrowers with less than 20% down payment or those who choose this option for convenience. Your lender collects approximately 1/12 of your annual property tax bill with each monthly mortgage payment, holding these funds in escrow until tax payments are due. Lenders typically pay your property taxes directly to the Washburn County Treasurer during the scheduled payment periods.

The County Treasurer handles property tax collection through two installment payments annually, with specific due dates varying by municipality within the county. Your mortgage servicer will receive tax bills and payment notices directly from the county. It's important to verify that your lender has the correct mailing address for tax bills, as any changes in your mortgage servicer must be communicated to the County Treasurer's office. You can verify that your taxes have been paid by checking with the Washburn County Treasurer's office or through their online payment portal if available.
