How Property Tax Works

Florence County, Wisconsin operates under the state's property tax system, which serves as the primary funding mechanism for local government services including schools, county operations, municipal services, and various special districts. Property owners in Florence County experienced significant assessment changes in 2025, with the county showing the largest equalized value increase statewide at 17.84%, reflecting strong market appreciation and new construction activity.

The effective property tax rate in Florence County varies by location within the county due to overlapping taxing jurisdictions including school districts, municipal governments, technical college districts, and special purpose districts such as fire protection or library districts. Wisconsin's base property tax rate averages around 1% statewide, but actual rates in Florence County may differ based on your specific property location and the combination of local taxing authorities that serve your area. Property owners should expect rate variations depending on which municipality, school district, and special taxing districts apply to their specific property location.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Florence County are additional property tax assessments that occur when there are changes to property ownership, value, or use outside the regular assessment cycle. Common triggers include new construction completion, property ownership transfers, or corrections to assessments discovered after the regular tax roll is finalized.

When supplemental taxes apply, they are calculated based on the difference between the previous assessment and the new assessed value, prorated for the portion of the tax year remaining. For example, if a new home construction is completed and occupied in January with a $400,000 assessed value on previously unimproved land assessed at $50,000, the supplemental tax would be calculated on the $350,000 increase in assessed value, multiplied by the applicable tax rate and prorated for the remaining months in the tax year. Property owners receive separate supplemental tax bills with their own due dates, typically 30-60 days from the bill date.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Florence County require property tax escrow accounts for borrowers with less than 20% down payment, though some lenders may require escrow regardless of down payment amount. Your lender collects monthly escrow payments along with your mortgage payment, typically calculating 1/12th of your annual property tax bill plus a small cushion for potential tax increases.

Florence County property taxes are generally paid in two installments (April and December), and your lender will make these payments on your behalf from your escrow account. Lenders must provide annual escrow analysis statements showing projected taxes, actual payments made, and any account surplus or shortage. If your property taxes increase significantly due to reassessment or rate changes, your lender may require higher monthly escrow payments or collection of a shortage amount. Property owners should verify that their lender is making timely tax payments and maintain records of escrow transactions to ensure proper payment to Florence County.
