Part 1: A basic guide to taxes and assessments
As ag vehicles travel along rural roads and the fall harvest draws closer in Waupaca County, property owners here may have seen assessment notices arrive in the mail. For farmers, homeowners, and business owners, property taxes are one of the larger bills that come due each year. Still, the way those bills are calculated can be confusing, especially when a community has gone through a revaluation.
Knowing how assessments connect to tax bills helps residents better understand what they are paying for, how local budgets are funded, and why a new assessment does not always mean a higher tax bill.
The basics of assessments and taxes
A property tax is a tax placed on real estate value. In Wisconsin, the state constitution requires uniform property taxation, meaning properties within the same municipality must be taxed fairly relative to their market value.
State law groups real estate into several categories. In rural communities such as Iola and Scandinavia, those categories are easy to recognize: Residential: Single-family homes, cottages, and similar dwellings. Commercial: Downtown storefronts, restaurants, and other local businesses. Agricultural: Active farmland, which is assessed under a special use-value system. Ag-forest and undeveloped land: Woodlots, wetlands and acreage that is not currently being farmed.
Why municipalities reassess property
Towns and villages hire assessors to complete periodic revaluations for two main reasons: to keep the property tax burden fairly distributed and to bring assessed values back in line with the local real estate market, according to the Wisconsin Department of Revenue.
Property values do not all change at the same pace. A house near Silver Lake or Lake Iola may rise in value faster than a farmhouse on a ridge, while another parcel may see little change at all. When assessments fall behind the market, some property owners can end up carrying more than their share of the tax burden while others pay less. A revaluation resets the comparison, so properties are measured against current values rather than outdated ones.
How municipalities set tax rates
One common misunderstanding is that a local board simply sets the tax rate directly. In practice, towns, villages, counties and school districts set a tax levy. The levy is the total amount of money a taxing body needs to collect from property owners to pay for services such as road maintenance, public safety, and schools, as explained by the Wisconsin Taxpayers Alliance.
The basic formula is:
Property tax rate = total tax levy ÷ total assessed value of the municipality.
For example, a town’s base rate might look like this before individual property values are applied:
Wisconsin law also limits how quickly local property tax levies can grow. In general, a municipality’s levy increase is tied largely to new construction.
School districts don’t fall under this new-construction-based levy limit. School district revenue is instead governed by a separate state formula tied to enrollment: districts calculate their allowable revenue using a three-year rolling average of pupil counts, plus a per-pupil adjustment set by the state each budget cycle. That means a growing tax base from new construction doesn’t by itself give a school district more room to levy.
A school district with flat or declining enrollment, like many in rural Wisconsin, can see its revenue limit hold steady or shrink even as local property values rise. A district can exceed that limit only through a voter-approved referendum or a few narrow statutory exceptions. So, when a revaluation reshuffles who pays what, it changes how the existing school levy is divided among taxpayers. It doesn’t change how much the district can collect in the first place.
What a revaluation means for your tax bill
A higher assessment by itself does not automatically lead to a higher tax bill. What matters is how much a property’s value changes compared with the rest of the municipality.
It may help to picture the total tax levy as a pie. Each property owner pays a slice of that pie based on the property’s share of the municipality’s total assessed value. If a property represented 1% of the total value before revaluation and still represented 1% afterward, that owner would still pay about 1% of the total tax levy.
When values rise across an entire community, the tax rate per $1,000 of assessed value often drops because the same levy is spread across a larger total value. The effect on an individual bill depends on how that property compares with the local average: Above-average increase: If a property’s value rises more than the municipal average, the tax bill will likely increase. Average increase: If a property’s value rises at roughly the same rate as the municipality overall, the tax bill should remain about the same, assuming the levy does not change. Below-average increase: If a property’s value rises less than the municipal average, the tax bill may decrease.
Context for Iola and Scandinavia
Tax burdens differ from one community to another because each municipality has its own mix of homes, farms, businesses, and public-service needs. County financial records show that the Village of Iola has a more concentrated residential and commercial center, with local budgets supported heavily by neighborhood homes and Main Street properties.
The Village of Scandinavia and the surrounding township include a larger share of agricultural and ag-forest land. Because Wisconsin values agricultural land by its use rather than its potential development value, the tax burden in farming areas can fall more heavily on farmhouses, residential structures, and other non-agricultural property.
