City Assessor Information

NEW for 2021!
Aside from the normal publication and notices which will still be used, the City of Delafield has created a Notify Me for people who only want to know when the BOR date has been chosen and what it is. Sign up through Notify Me in the upper right of the homepage today! 

The Board of Review meets annually anytime between anytime during the 30-day period beginning on the second Monday in May. 

All Boards of Review must be in session at least 2 hours. After this first meeting, the Board may then adjourn at its own discretion from time to time, until its business is completed. However, whenever the Board adjourns for more than one day the Clerk must post a written notice on the meeting place door, stating the date and time that the Board will resume meeting.

Assessed vs. Equalized Value:

Assessed Value :   This is the dollar value placed on a parcel of property by the City Assessor.   It is computed by analyzing thousands of individual sale transactions, thousands of inspections and a thorough study of all Delafield neighborhoods.   It is the assessor’s estimate of market value.   It is important for maintaining equity between and among all taxpayers in the city.

Equalized Value :   Is calculated by dividing the property’s total assessed valued by the average assessment ratio. This ratio is applied to all property, including personal property, regardless of type or location of the property.   In theory, this should approximate the current market value of the property.   This value estimate is determined by the Department of Revenue (DOR).   It is used to apportion tax levies among municipalities and is used in the distribution of shared revenues.  

History : Back in the early 1980’s, when the legislature passed the law that this be included on all tax bills, was a time across Wisconsin when assessors for the over 1800 municipalities were not required to assess property at market value during any time interval. As a "truth in taxation" measure, the legislature thought it was important for their constituents to know what in terms of value their assessment actually meant.  Because the DOR already prepared municipal "equalized values," the legislature thought that these estimates made at the municipal level should be provided at the property level.   This was an easy answer to their problem.   Remember, the intent was to show whether the assessment on a property was at all accurate.   It was never meant to actually be your individual property estimate.   But, at least from the taxpayer’s standpoint, it meant more than the assessment at that time.  For instance, if the assessor was assessing property in your municipality at 10% of fair market value (and you had no idea of that fact) and your tax bill showed an assessment of $10,000 you might think "boy am I getting a good deal--I know my house is worth at least $60,000."   However, if you realized that the $10,000 actually equated to approximately $100,000; you might not be so happy.   (Since 1986, after this was enacted, the legislature tightened the law and we now are required to assess within 10% of market value at least once in every four year period.)

The reason DOR equates all municipalities to an estimate of fair market value (equalized value) each year is to ensure the uniform distribution of shared taxes across municipalities.   The assessor, on the other hand, assesses each property to make sure that each property pays their fair share of tax on an individual level.

The equalized value on the tax bill is a less reliable estimate than that prepared by the assessor.   The DOR has never inspected any property in the City of Delafield.   It is only to be used as a tool to check your assessment.  

The important thing to point out is that ALL property in Delafield had that same factor applied to it to determine its estimated fair market value (the "assessment ratio").   Also, it is important that you know that it is the assessed value, in all cases, used to calculate your property taxes.   If we used the "equalized value" the taxes would not change.  

State law requires assessors be within 10% (higher or lower) of the state’s equalized value ratio at least once in every four year period.  Delafield is not, nor ever has been, out of compliance with this requirement.   The Department of Revenue allows this leeway because appraisal is not an exact science, and to allow for the different standards used by them versus a municipality.  Remember, the "equalized value" is an "estimate" and is only "approximate".
