Real Property and Tax Data

Tax BillS

The County prints the tax bills and hands them off to the municipalities to mail out.  The County serves only as a collection agent for the taxing authority (municipality).  Please check Novus (tax bill tab) to view your tax bill, and to see the mill rate for your municipality. 

Our most common Tax Bill FAQs:

  • Question: I split or merged my parcel this year, but the tax bill I received is for the parent parcel (before the split or merge) - why is that?
    • Answer: Whenever parcel boundaries change in any way, the new parcels won't receive their tax bills until the following year.  This is because they get sent to the assessor to add on new codes and values.
  • Question: I recently sold my parcel, but I still received a tax bill.  Why didn't it go to the new owner? (Also a buyer didn't receive a tax bill on newly purchased property)
    • Answer: If the transfer occurred just before we printed the tax bills, ownership was not quite yet updated.  You can give the tax bill to the new owner to pay, or work with the title company on any pro-rating questions.  We or your municipality can send the tax bill to the new owner as needed.

The Real Property Lister is responsible for the county’s real property listing and associated assessment functions, supplying parcel-based land information to both land information professionals and to the general public.

Property listing & Tax Information (NOVUS)

NOVUS is the county’s online tax, property, and assessment information database. Use NOVUS to view property listings and tax information.


Tax ID numbers and PIN numbers are two different ID numbers placed on each parcel in the county. Your PIN is a 23 digit number, while tax ID numbers are between 1 and 5 digits. Get a detailed explanation of how these PIN numbers are derived.

Assessment Information

  • No county in Wisconsin currently operates a County Assessor Office. Property valuation is handled at the local level by municipality.  Find your assessor.
  • For information on appealing your assessment, tax process, and more, see the Guide for Property Owners from the Wisconsin Department of Revenue.
  • is an external website that hosts some basic assessment information.


After a deed is recorded in the Register of Deeds office, it will move to the office of the Real Property Lister where the ownership and documentation will be updated in NOVUS.


When a parcel is either split or combined with another parcel, the Real Property Lister assigns new Tax ID and PIN number(s), adds in all appropriate ownership, documents, and basic listing information, and then sends to the assessor to add on assessment values. GIS mapping is also updated; please note that updates to the GIS Web Map after NOVUS is updated are not immediate. Please see our guides on each, plus supplementary FAQ and electronic real estate transfer return (eRETR) guides from our Register of Deeds office:

Unsure of property lines?

In addition to reading your deed, a survey is the best way to know your property boundaries. Please note that our GIS Web Map only shows approximate parcel lines and can be up to 200 feet off in some cases. First check if your land has a survey on it - recorded Certified Survey Maps (CSMs) are in the Register of Deeds office, while maps of survey (not recorded) are in the Land Records Department and seen online in our GIS Web Map.  To contact a land surveyor, see the list on our Land Surveying page.
