Counties in North Carolina are required to revalue real property every eight years; however, some counties chose to do so in shorter intervals. According to the North Carolina Department of Revenue, thirteen counties are set to revalue in 2012, including Bertie, Cabarrus, Cherokee, Franklin, Guilford, Madison, Montgomery, New Hanover, Pamlico, Pitt, Rutherford, Surry and Watauga. In these counties, taxpayers will receive revaluation notices based on the value of their real property as of January 1, 2012. These notices are typically mailed in late January or February and provide taxpayers an opportunity to appeal. In revaluation years, counties typically encourage taxpayers to go through an informal review process prior to filing a formal appeal.
