It is the mission of the Greene County Assessor’s Office to provide fair, accurate and equitable assessments to all property owners in Greene County, Iowa.


Duties of the 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 otherwise provided by law.  This would include residential, multi-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.

General Misconceptions About the Assessor's Duties

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 county, 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 property in your taxing district.

Dates to Remember

  • January 1 - Effective date of current assessment.
  • April 1 through April 25 - Taxpayer may inquire about their assessment and may also request an informal review of the assessment by the assessor under one or more grounds for protest.

  • May 1 through Adjournment - Board of Review meets each year.
  • July 1 - Signup deadline Homestead Tax Credit and Military Exemption 
  • January to November 1 - Signup period for Family Farm Tax Credit
  • October 9 through October 31 - Protest period for filing with Board of Review on properties affected by changes in value as a result of the Director of Revenue and Finance Equalization Orders (odd numbered years only).
