The state Department of Revenue (DOR) values all homes, not the county. It works through local field offices; each county is served by one. Appeals go first to the County Tax Appeal Board (CTAB), a local board appointed by the county commissioners that is not part of the DOR. Find your county for contact details, local tax figures and a step-by-step guide.
