There are two major components of the tax system: taxation and valuation. Our office establishes the assessed value of parcels of property in the township. Taxing authorities such as school districts and municipalities are responsible for the second major component of the tax system: Taxation. They levy (impose) taxes against the property values established by the assessor. Our staff will be happy to discuss concerns or questions you may have about the tax system.

Property owners may appeal the assessed value of their property. An appeal is not a complaint about higher taxes. Rather, it is an attempt to prove that a property’s estimated market value is unfair or inaccurate.
Determining Assessed Value
The purpose of assessed value is to proportion the tax burden over all taxable property in a fair and equitable manner. The assessed value of a parcel of property is set at 1/3 of its market value. Every year, our office determines the market value of each taxable parcel of property in the township. Characteristics of your property (size of lot, type of home, number of bathrooms, garage, swimming pool, etc.) and characteristics of the neighborhood are taken into consideration when determining market value.
As noted, the Assessor’s office is not responsible for the second major component of the tax system: taxation. However, we are including a few facts about taxation and would be happy to discuss this component of the tax system in more detail with you.
