Welcome to the St. Clair County Department of Equalization Website.
What we do
The Equalization Department annually advises and assists the Board of Commissioners in determining the true cash value of the county and equalizing the property tax assessments on a county-wide basis. To achieve this monumental task, the department conducts annual sales and appraisal studies for each class of property. These studies are used to equalize assessed values for all classes of property in all thirty-one local units of government within St. Clair County.
The process of County Equalization is mandated by Section 211.34 of the General Property Tax Act of the State of Michigan, which states in part that the County Board of Commissioners shall examine the assessment rolls of the townships or cities each year for uniformity and equity.
The General Property Tax Act goes on to state that the County Board of Commissioners of a County shall establish and maintain a department to survey assessments and assist the Board of Commissioners in the matter of equalization of assessments.
The Equalization Department's main purpose is to correct the inequities that may occur between local units of government as a result of under or over assessment of a property class.
The Equalization Department does not determine an individual assessment, that is the sole responsibility of the local assessor.
The Equalization Department updates real property tax rolls so all records have current names, addresses and land descriptions. Our services extend County-wide except for the city of Port Huron.
The GIS Department creates tax maps and reviews land division requests for compliance with the Land Division Act. All land division requests must include a scale drawing of the proposed divisions, showing lot lines, dimensions, acreages, section numbers, township etc. Please contact your Assessor for instructional packet.
Before any of the changes can take effect, approval from the local unit of government must be attained by the person(s) requesting the change on special forms available at our office or from your local assessor.
