The city of Statesboro will hold two property tax increase hearings Thursday, at noon and 6 p.m., in the council chambers at City Hall. These, and a third public hearing scheduled for 9 a.m. Sept. 5, are required because city officials propose an increase of up to 1 mill in the tax rate. A one-mill increase would add $40 to the annual tax on a home with an appraised fair market value of $100,000.
