Revaluation and taxation are separate. Revaluation determines the market value. The Mecklenburg Board of County Commissioners and Town of Cornelius determine tax rates during the annual budget process in late spring. Budgets will be adopted by June 30, 2019. The value of your property combined with the tax rate determines your property tax bill, which is mailed in late July. The County makes up the majority portion of the taxes you pay (76.4%), and the Town of Cornelius is the balance (23.6%).
