Office of the Assessor

 The Vernon Township Assessor is your liaison to the Chief County Assessment Office. The Township Assessor is an elected position (4-year terms). The assessor must be certified by the State and meet continuing education requirements. 

The job of the assessor is to value all taxable parcels of property within the township in a uniform manner, so all properties are valued at the same approximate assessment level. This creates a fair share spread of the real estate tax burden. The assessor has no say or control of the tax monies requested of any given taxing district.
