Protesting Your Property Taxes
If you feel your Property assessment was made in error you may file a written protest with the five member Dickinson County Board of Review. The Board operates independently of the assessor's office, and has the power to confirm or to adjust either upward or downward any assessment. Normally your written protest must be filed between April 2nd and April 30th of the year.
Iowa law about how protests are handled is Section 441.37
