The Notice of Assessment of Land and Improvements (Form 11) is an assessment notice that is sent to taxpayers by the county or township assessor. The assessed value on the Form 11 is the starting point for calculating annual property tax payments. Assessed values may change when there is new construction, additions, remodeling, or changes in land use. A taxpayer has the right to file an appeal with the county assessor, should they disagree with the assessment.
A county has the option to use the tax bill as the Notice of Assessment. The notes section will provide additional information from the counties regarding the notices. Questions should be directed to the phone number and/or email address provided in the contact box for the county where the property is located.
The following information is provided by the county or township assessor and is a courtesy to taxpayers.
