How Property Tax Works

Pierce County, Wisconsin operates under a property tax system that funds essential local services including schools, law enforcement, road maintenance, and county operations. Property taxes are calculated using an assessment ratio of 0.620305754 for the 2025 tax year, which helps determine the estimated fair market value shown on tax bills. The actual tax burden varies significantly depending on your location within Pierce County due to overlapping special taxing districts such as school districts, municipal services, and special assessment areas.

Property owners can expect effective tax rates that generally align with Wisconsin's statewide average of approximately 1% of assessed value, though individual rates may be higher or lower based on local levies and special district assessments. The county reassesses properties periodically, and property owners have appeal rights if they believe their assessment is incorrect. Most tax relief programs require annual applications and are not automatically applied to your tax bill.

When Are Property Taxes Due?

For the 2025/2026 tax year in Pierce County, property taxes are due in two installments:

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 Pierce County are additional property tax bills issued when there are changes to property ownership, new construction, or property 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 remaining portion of the tax year.

For example, if you complete a $50,000 home addition in June and the annual assessment was completed in January, you would receive a supplemental tax bill covering July through December for the increased assessed value. The supplemental tax amount would be calculated using the same tax rate as your regular property tax bill, applied only to the improvement value and only for the remaining months of the tax year.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Pierce County require borrowers to maintain an escrow account for property tax payments. Your lender collects monthly payments equal to 1/12 of your estimated annual property tax bill, plus a small cushion as allowed by federal law. The lender receives your tax bills directly and pays them on your behalf by the April 30 and October 31 deadlines.

Each year, your lender will provide an escrow analysis showing whether you have a shortage or surplus based on actual tax bills versus collected amounts. If taxes increase, your monthly payment will adjust accordingly. Property owners should verify that their lender receives current tax bills and makes timely payments, as you remain ultimately responsible for ensuring taxes are paid even when using escrow services.
