Assessments, Assessor & Taxes


Property assessment is regulated by State Statutes through the State Department of Revenue. The Town is required to assess all taxable real and personal property within the limits of the Town of Dekorra at it full and true value (the fair market value that would be obtained at private sale). Agricultural property is treated differently and is assessed based on the land’s use rather than fair market value.

Residents may compare their property value with other property at the Open Book informational meeting with the assessor and may appeal an assessment at the Board of Review hearings.

Tax bills are sent out as early as possible in December (often received in the last 2 weeks).

The preferred method of payment is to mail payment to: Town of Dekorra Treasurer, W8495 County Rd. JV, Poynette, WI 53955, payable to Town of Dekorra. Payment in full or at least the first payment is due January 31 and the second payment if there is one is due July 31 The second payment must be sent to and payable to the Columbia County Treasurer, PO Box 198, Portage, WI 53901.

If a Lottery Credit does not appear on your tax bill and you were a resident of the Town of Dekorra, please notify the Town of Dekorra Treasurer. A Late claim form can be obtained and the Lottery Credit will then be applied to your tax bill upon receipt of the signed form.

Every taxable parcel that has real property qualifies for the credit. (Mobile Homes or improvements on leased land do not qualify). The Credit is calculated by multiplying the lower of the Calculated Equalized Value or the Maximum Credit Value (determined by the Wisconsin Department of Revenue) times the Equalized Value School Tax Rate. The credit will be located above the Lottery Credit line of your tax bill if you are eligible for the credit. The County Treasurer will determine if you are eligible, so there is no need to apply for the credit.

The amount of property tax collected that goes to the Town is a relatively small percent of the total (about 10%). Much larger percentages go to the County and School District.

2021 Property Revaluation

The Town of Dekorra will be performing a market revaluation in 2021. The last time Dekorra performed a revaluation of all property was in 2007, 14 years ago. Since then, the market has changed and assessed values no longer reflect the current market.

The state of Wisconsin is a Market Value state. This means property values are required to mirror the fair market value of comparable properties to ensure property owners are paying their fair share of taxes.

The fair market value of all property is calculated by reviewing arm’s length sales between a willing seller and a willing buyer on the open market. Assessors consider information from many sources to determine your assessment.

Assessors will be reviewing market sales up to January 1, 2021. Sales after the new year will not be used to determine your new value. The property tax bill you receive in December of 2021 will be based on the new assessment value of your property.

Assessors don’t set tax rates. There are no additional taxes collected by the town during a revaluation. The revaluation does not change the amount of tax collected by the town, county, school district or technical college.

To learn more about what assessors do, please watch the video: Assessor Video 2020


Timeline of Revaluation:

  • Jan – Feb: Assessors review previous year’s sales and market data
  • Jan – March: Trespass letter will be sent to properties assessors need to visit
  • Feb – March: Permits and sales are verified
  • Feb – March: Comparable market data used to revalue all property
  • April – May: Notice of new value will be mailed to you
Open Book

The Town Assessor, upon completion of the review of assessments, and prior to completion of assessment rolls, will hold Open Book conferences. The purpose is to provide property owners and their agents the opportunity to review and compare assessed values. The assessor will send notice to each property owner whose assessment has changed at least 15 days prior to the first open book conference.

Monday, June 21st from 12-7 pm

Open book is a conference, either face-to-face or over the phone, with an assessor to discuss the value of your property. You have until 48 hours before Board of Review to contact the assessor about your new value. When available you can set an appointment with an assessor here:

Board of Review

Saturday, July 31st starting at 9:00 am

The Board of Review functions like court and is required to evaluate evidence-based on facts. You or your representative must provide factual evidence that your property is inequitably assessed. The burden of proof is solely on the taxpayer. The assessor’s value is presumed correct by State Law until proven otherwise.
