Assessor

Assessors Office Building with Assessor Charlie Mullin standing in frontThere 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.
