Hall County taxpayers got good news from their school district this week, but it comes with a big asterisk moving forward: Don’t count on your taxes staying low if things don’t change. Hall schools’ next fiscal year general fund budget of $263 million includes no tax hikes for county residents, and a small drop in the millage rate. But the increased cost for teachers and other personnel taking greater share of school budgets each year makes that tax rate “unsustainable” in the future, according to Superintendent Will Schofield.
