State law (Section 70.32 of the WI Statutes) requires the assessment of taxable property (except agricultural, agricultural forest, and undeveloped) at full value as of January 1 each year. Assessments at a percentage of full value are acceptable when applied uniformly. To determine if your assessment is fair, you must analyze it in relation to full value. This is done by dividing your assessment by the general level of assessment for your municipality, which is estimated to be 100.00%.
Under Wisconsin law, generally, the assessor may not change the assessment of property based solely on the recent arm's length sale of the property without adjusting the assessed value of comparable properties in the same market area. For information on the assessment of properties that have recently sold, visit the Internet site of the Department of Revenue at https://www.revenue.wi.gov/Pages/ERETR/data-home.aspx .
To Appeal Your Assessment
First, discuss with your local assessor. Questions can be asked at any time, cvogel [at] cityofmequonwi.gov (email )or phone is best. Questions can often be answered by the assessor and not require an appeal to Board of Review (BOR).
To file a formal appeal, give notice of your intent to appeal by contacting the BOR clerk at least 48 hours before the BOR begins. Complete and file your appeal form with the BOR clerk no later than the first two hours of the BOR's first meeting. Make sure you file a completed form or the BOR may not review your appeal.
For more information on the appeal process, contact the municipal clerk listed above. Review the "Guide for Property Owners" from the Department of Revenue page.
