The value of property exempt from Hall County school taxes has increased 259 percent in the past decade while the overall value of property in the tax digest prepared for the school system has increased by only 11 percent in the same time. Nath Morris, chairman of the Hall County Board of Education, said the combination of the increasing exemptions and the plummet in property values during the recession create funding problems for the school district. Full school tax exemptions are granted on property belonging to residents age 70 or older.
