Assessors Function
The Township Assessor is required by law to uniformly assess properties at a median level of 33 1/3% (one third) of market value. Equitable assessments ensure a fair distribution of the property tax burden among all property owners. Local property taxes pay for such services as schools, villages, libraries, park districts, and fire protection districts.
