The Bulloch County Board of Education is rolling back its millage rate 1 percent to avoid what would have to be announced as an increase in property taxes. Even so, total revenue and local revenue to the schools still will increase compared to last year’s. Under a 1999 law called the Georgia Taxpayers Bill of Rights, local governments must announce a tax increase and hold three public hearings if millage rates remain the same but property revaluations result in increased revenue.
