How Property Tax Works

Marquette County, Wisconsin operates on a property tax system that funds essential local services including schools, county operations, municipal services, and special districts. Property taxes are the primary funding source for local government operations, with tax bills sent out twice yearly in July and December. The effective tax rate for 2025 is estimated at approximately 28.28 mills (or $28.28 per $1,000 of assessed value) for principal residences with taxable values around $50,000, though this represents just one component of the total tax burden.

Actual property tax rates vary significantly throughout Marquette County depending on your specific location and the special taxing districts that serve your property. These districts may include school districts, technical college districts, municipal services, and other local assessment districts. Each property owner's total tax rate reflects the combined levies of all applicable taxing jurisdictions, making it essential to understand your specific district assignments when calculating your property tax obligation.

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 Wisconsin typically occur when there are significant changes to a property's assessed value during the tax year, such as new construction, major improvements, or ownership transfers that trigger reassessment. In Marquette County, supplemental taxes would be calculated based on the difference between the original assessed value and the new assessed value, multiplied by your applicable tax rate, prorated for the portion of the tax year remaining.

For example, if you complete a $100,000 home addition in September and your total tax rate is 28.28 mills, the supplemental tax would be approximately $1,414 ($100,000 × 0.02828 × 50% for half the tax year). Supplemental taxes follow the same payment schedule as regular property taxes and become part of your overall tax obligation for that levy year.

Escrow & Property Taxes

Most mortgage lenders in Marquette County require property tax escrow accounts for properties with loans exceeding 80% loan-to-value ratio. Your lender collects monthly property tax payments along with your mortgage payment and maintains these funds in an escrow account. Since Marquette County issues tax bills in July and December with payments due by March 1 of the following year, lenders typically pay your taxes directly to the appropriate township or city treasurer before the March 1 deadline.

It's important to review your annual escrow analysis statement and verify that your lender has current tax information, especially after reassessments or successful appeals. If you pay taxes directly without escrow, remember that payments are accepted by township and city treasurers until March 1, after which delinquent taxes are transferred to the County Treasurer with additional penalties and fees applied.
