The assessor is charged with several administrative and statutory duties; however, the primary duty and responsibility is to cause to be assessed all real property within his/her jurisdiction except that which is otherwise provided by law. This would include residential, commercial, industrial, and agricultural classes of property.

Real property is revalued every two years. The effective date of the assessment is January 1st of the current year. The assessor determines a full or partial value of new construction, or improvements depending upon the state of completion as of January 1st.

The Assessor  does not:

• collect taxes.
• calculate taxes.
• determine tax rate.
• set policy for the Board of Review.

The Assessor is concerned with value, not taxes.  Taxing jurisdictions such as schools, cities, and townships, adopt budgets after public hearings.  This determines the tax levy, which is the rate of taxation required to raise the money budgeted.  The taxes you pay are proportionate to the value of your property compared to the total value of the taxing district in which your property is located.
