Assessment Process
Assessment Process
Wisconsin has an annual assessment. This means that each year’s assessment is a new assessment. The assessor is not obligated to keep the same assessment each year. The assessor may change your assessment because of building permits or sales activity even if he or she did not inspect your property.
The law requires that property be valued from actual view or from the best information that can be practicably obtained. An interior inspection results in a higher quality assessment due to more comprehensive information in reference to building layout, design, quality, and condition. It is not always possible to conduct interior inspections. If a property owner denies entry to view the property, the assessor may send a certified letter requesting entrance to the property to view it.
If the property owner still refuses admittance, the assessor values the property using the best evidence available.
The municipal assessor is responsible for the assessment process:
• Discover – all real property is subject to tax unless exempted by law
• List – property characteristics determine value
• Value – determine the value subject to property tax
Frequently Asked Questions About Property Tax Revaluations in Rural Wisconsin
Understanding Property Assessments and Revaluations
​
Q: What is a property tax assessment?
A: A property tax assessment is the assessor's estimate of your property's market value as of January 1 of a given year. Wisconsin law requires that property assessments reflect market value as accurately as possible. This assessed value is used to distribute the local property tax burden fairly among property owners.
​
Q: What is a revaluation?
A: A revaluation is a systematic review and update of property assessments within a municipality. During a revaluation, the assessor analyzes recent sales, property characteristics, construction costs, market trends, and the Wisconsin Department of Revenue's Equalized Values to bring assessments closer to current market values.
A revaluation may involve:
-
Exterior property inspections
-
Property data verification
-
Analysis of recent real estate sales
-
Updates to property records
-
Adjustments to assessed values based on market conditions
-
​
Q: Why are revaluations necessary?
A: Revaluations are necessary because real estate markets change over time. If assessments are not updated periodically, they become less accurate and unequal.
Reasons for revaluation include:
-
Changes in the real estate market. Property values may increase or decrease due to market conditions.
-
Fairness among taxpayers. Some properties may appreciate faster than others. Regular revaluations help ensure each property owner pays their fair share.
-
Compliance with Wisconsin law. Municipalities are expected to maintain assessments that reasonably reflect market value.
-
Correction of assessment inequities. Over time, similar properties can become assessed at significantly different percentages of market value.
-
​
Q: Does a revaluation mean my taxes will automatically increase?
A: No. This is one of the most common misconceptions about revaluations.
A revaluation changes the way the tax burden is distributed among property owners. It does not automatically generate additional tax revenue for the municipality.
Your actual tax bill depends on:
-
Your property's assessed value
-
The total value of all taxable property in the municipality
-
The tax levy established by local governments, schools, counties, and special districts
-
​
Q: What is the typical result for most property owners after a revaluation?
A: In many rural Wisconsin communities, the typical result is that assessed values increase because assessments have not kept pace with rising market values.
However, when most properties in a community increase by roughly the same percentage:
-
Property values go up.
-
The total tax base goes up.
-
Tax rates generally decrease.
-
The average property owner's tax bill may remain relatively similar, changing only due to normal levy increases or shifts in property values relative to neighboring properties.
For example:
Before Revaluation After Revaluation
Home assessed at $150,000 Home assessed at $225,000
Tax rate: $20 per $1,000 Tax rate: $13.33 per $1,000
Tax bill: $3,000 Tax bill: $3,000
In this example, the assessment increased significantly, but the tax bill remained the same because the tax rate decreased proportionally.
​
Q: When would a property owner's taxes increase after a revaluation?
A: Taxes may increase if:
-
Your property's value increased more than the average property in the municipality.
-
Major improvements were made to the property.
-
Market demand for your type of property grew faster than other properties.
-
Local governments increased their tax levies.
-
​
Q: When might a property owner's taxes decrease after a revaluation?
A: Taxes may decrease if:
-
Your property's value increased less than the community average.
-
Your property's market value declined.
-
Other classes of property experienced greater appreciation.
-
Assessment inequities were corrected in your favor.
-
​
Q: Why do rural properties sometimes see larger assessment changes?
A: Rural areas often experience periods where assessments remain unchanged for many years while market values continue to rise. When a revaluation is finally completed, assessment increases can appear dramatic even though they simply reflect market changes that have accumulated over time.
Additionally, rural properties with:
-
Significant acreage
-
Recreational land
-
Waterfront frontage
-
Hunting or timber land
may experience market trends that differ from residential properties in town.
​
Q: What should I do if I disagree with my new assessment?
A: Property owners should first review the assessment notice and verify that the property's characteristics are correct, including:
-
Square footage
-
Acreage
-
Buildings and improvements
-
Number of bedrooms and bathrooms
-
Other property features
If concerns remain, contact the assessor to discuss the valuation. Property owners also have the right to attend the Board of Review and appeal the assessment through the procedures provided under Wisconsin law.
​
Q: What is the key takeaway about revaluations?
A: A revaluation is primarily a fairness tool, not a tax increase. The goal is to ensure that all properties are assessed consistently and that the local tax burden is distributed equitably. While assessed values often rise after a revaluation, the typical property owner does not experience a proportional increase in property taxes simply because the assessment increased. The most important factor is how a property's value changes relative to other properties in the community.
​
Summary
My assessment went up. Does that mean my taxes will go up by the same percentage?
Usually, no. In a typical rural Wisconsin revaluation, most property values increase together. When that happens, tax rates generally adjust downward. The result is that many property owners see little change in their tax bill unless their property's value changed significantly more or less than the average property in the municipality.

Assessment classifications
Assessment classifications
State law requires the assessor to classify land on the basis of use. Classification affects the assessed value.
Eight statutory classifications for real property:
Residential (Class 1) – sec. 70.32(2)(c)3., Wis. Stats.
» Any parcel (or part of a parcel) of untilled land not suitable for the production of row crops, on which a dwelling or other form of human abode is located
» Vacant land where the most likely use is residential development
» Mobile homes assessed as real property are classified as residential
» Apartment buildings of up to three units are also classified as residential
Commercial (Class 2)
» Land and improvements primarily devoted to buying and reselling goods
» Includes the providing of services in support of residential, agricultural, manufacturing and forest uses • Manufacturing (Class 3)
» State law (sec. 70.995, Wis. Stats.), provides for the state assessment of manufacturing property
» Contact the Manufacturing Bureau District Office for information on qualifying uses
Agricultural (Class 4)
» State law (sec. 70.32(2)(c)1g., Wis. Stats.), describes this as "land, exclusive of buildings and improvements, which is devoted primarily to agricultural use"
» Land devoted primarily to the production of crops (excluding forestry operations) or the keeping, grazing, or feeding of livestock for the sale of livestock or livestock products
» Buildings and dwellings associated with growing, production and associated services are classified as "Other" (Class 7)
» Agricultural Assessment Guide for Wisconsin Property Owners provides classification examples
Undeveloped (Class 5) – sec. 70.32(2)(c)4., Wis. Stats.
» Areas commonly called marshes, swamps, thickets, bogs or wet meadows
» Fallow tillable land (assuming agricultural use is the land’s highest and best use)
» Road right-of-way, ponds and depleted gravel pits
» Land because of soil or site conditions is not producing or capable of producing commercial forest product
Agricultural forest (Class 5m)
» Under state law (sec. 70.32(2)(c)1d, Wis. Stats.), defines agricultural forest as land producing or is capable of producing commercial forest products, if the land satisfies any of the following:
- Forest land is contiguous to a parcel that is classified in whole as agricultural land. The forest land and the contiguous agricultural parcel must have the same owner. Contiguous includes separated only by a road.
- Forest land is located on a parcel containing agricultural land for the January 1, 2004 assessment and on January 1 of the current assessment year
- Forest land is located on a parcel where at least 50 percent of the acreage was converted to agricultural land for the January 1, 2005 assessment year or thereafter
» Agricultural Assessment Guide for Wisconsin Property Owners provides classification examples
Productive forest land (Class 6) – sec. 70.32(2)(c)2., Wis. Stats.
» Land producing or capable of producing commercial forest products.
» Forested areas that are managed or set aside to grow tree crops for "industrial wood" or to obtain tree products (ex: sap, bark, seeds)
» Forested areas with no commercial use made of the trees, including cutover
» Cherry orchards, apple orchards and Christmas tree plantations are classified as agricultural property
» Lands designated Forest Crop Land and Managed Forest Land by the Department of Natural Resources are entered separately in the assessment roll »
» Forested areas primarily held for hunting, trapping or in the operation of game preserves, must be classified as forest, unless clearly operated as a commercial enterprise or exempt
Other (Class 7) – sec. 70.32(2)(c)1m., Wis. Stats.
Buildings and improvements on a farm (ex: houses, barns and silos along with the land necessary for their location and convenience)
