  • Note: This year (2019), because of the disaster declaration for Dickinson County (and other counties), the dates have been extended. The dates for written appeals are now April 2nd to June 5th. The Board of Review is in extended session, May 1st to June 15th.. The extended protest date is not due to damages caused by the disaster, but due to the taxpayer’s possible limited access to their mail, their property etc. This year’s disaster protest form with instructions can be found on the Internet at  https://dickinsoncountyiowa.org/assessor-board-of-review .
