Jordan Neve
Deputy Assessor


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 provided by law.  This would include residential, multi-residential, commercial, industrial, and agricultural classes of property.  Real property is revalued every two years, on odd-numbered years.  The effective date of the assessment is January 1st of the current year.  The assessor determines a full or partial value of the new construction or improvements depending upon the state of completion as of January 1st.

About the Assessor


*calculate taxes*

*determine tax rate*

*collect taxes*

*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.

Assessors are appointed to their positions by a Conference Board consisting of the members of the Board of Supervisors, the Mayors of all incorporated cities, and a member from each school district within the jurisdiction. A city with a population of ten thousand or more may elect to have their own assessor.

Assessors are required, by statute, to pass a state examination and complete a Continuing Education Program consisting of 150 hours of formal classroom instruction with 90 hours tested and a passing grade of 70% attained. The latter requirement must be met in order for the assessor to be reappointed to the position every six years. The Deputy Assessor also must pass a state examination as well as successfully complete 90 hours of classroom instruction of which at least 60 hours are tested.

The Conference Board approves the Assessor's budget, and after a public hearing, acts on adoption of the budget as presented.  The Assessor is limited, by statute, depending upon the value of the jurisdiction, to a levy limitation within the county budget.
