The Equalization Department advises and assists the Board of Commissioners in equalizing property tax
assessments on a county-wide basis. In conformance with state directives the Department conducts
annual sales and appraisal studies. These studies are used to equalize assessed values for each class
of property in each of the twenty-one local units of government within Ingham County. The Department
assists local assessing officers in the discovery, listing and valuation of properties for tax purposes,
and in the development and use of valuation standards and techniques for the assessment of property.
