Appeals Process

In order to provide property owners with more flexibility in being able to speak with the assessor, beginning in 2022 Accurate Appraisal will offer an extended period of Open Book via phone. The assessor will be available for calls to discuss property values from the time assessment notices are received until 48 hours before the Board of Review convenes.  For those property owners who prefer to have an appointment, there will be a daily schedule available on the Accurate Appraisal website here to sign up for a scheduled time to call. 

The assessor will explain how your assessment was prepared, review the property record for your property and explain what factors were considered in determining a value for your property. 

There will also be a 2-hour roll viewing open book period meant for community members to view the roll per state law requirements.

Frequently Asked Questions

What is assessed value?

Assessed Value is the value the city assessor places on each real property parcel and on each individual’s taxable personal property. Under state law, all non-agricultural assessments must be based on the property’s market value as of January 1 of the assessment year. State law recognizes that every municipality cannot be assessed exactly at market value each year. The law requires that each municipality is within ten percent of market value once every five years. Assessed values are used to distribute the City’s taxes among the individual property owners.

What do tax assessors do?

City tax assessors are state certified individuals whose duties are to discover, list, and value all taxable real property in the municipality in a uniform and equitable manner. In performing these duties, assessors are required to follow state law, case law, and the Wisconsin Property Assessment Manual. The property values determined by the assessor are then used to calculate the amount of property taxes to be paid. The assessor is not involved in the collection of property taxes. 

Category: Assessor
How is assessed value determined?

The law requires that property be valued from actual view or from the best information that can be practicably obtained. This information may include the sale of the property, review of new construction, review of improvements, or physical inspection of the property.

How will I know the amount of my assessment?

Whenever an assessor changes the total assessment of any real property the owner must be notified. (Failure to receive a notice does not affect the validity of the changed assessment.) The notice must be in writing and mailed at least 15 days (30 days in revaluation years) prior to the Board of Review meeting. 

You can also review your assessed value by visiting the assessor website here: http://accurateassessor.com/municipalities/

Select "Platteville, CIty of" from the list and enter your parcel number or street number and street name.

What if, after the informal Open Book process, I still disagree with the assessment?

You must file an Objection Form with the municipal clerk at least 48 hours prior to the meeting of the Board of Review. You will then appear before the Board of Review for a hearing where you will present your case regarding the assessed value of your property.

Category: Assessor
What evidence do I need to present to the Board of Review?

The best evidence of value is the recent sales price of your property. The next best evidence is the arm's-length sales of reasonably comparable properties.  These are properties similar to yours in location, age, style, condition, and other features that affect market value, such as the number of bathrooms, bedrooms, and size of the garage. More information can be found in the 2022 Guide for Property Owners located at the bottom of this page.

When will the new property assessment go into effect?

The new assessments are effective January 1 of the following year and will appear on the tax bill you receive in December of the current year.

What is a property assessment revaluation?

A revaluation is performed by the city assessor when the property records are outdated or inaccurate, assessment uniformity is poor, a full revaluation hasn’t been performed for ten years, or reassessment is required under state law (sec. 70.75, Wis. Stats.).

Revaluation types:

•  Full revaluation –  implies that present records are outdated or confidence in their accuracy is lost. It will entail on-site interior and exterior inspections, measuring, listing and photographing of all buildings.

•  Exterior revaluation –   is sometimes sought when there is not total confidence in the property record cards, but questions can be verified without interior inspection

•  Interim market update –  implies that there is confidence in the property record system and all that is needed is professionally performed valuation updating

The City is required by the State to undergo a revaluation whenever the equalized value of a class of property (residential or commercial) falls below 90% for several consecutive years. The City of Platteville underwent a Full Revaluation in 2018 and an Interim Market Update in 2022. Due to the significant changes in property values regionally and state-wide, the City Assessor will need to undertake an Interim Market Update in 2024. When the City undergoes a revaluation, it does not mean the City will collect more taxes because of the revaluation, but the distribution of those taxes may change based on the valuation of individual properties.
