When Hall County officials announced last week they were considering a tax increase to balance the 2015 fiscal year budget, it raised more questions than answers. Because of growth in the tax digest, or taxable property, primarily due to reassessments of lakefront homes, the county would have to roll back the tax rate to 5.98 mills to remain revenue neutral in the next fiscal year. But with the prospect of generating an additional $1.4 million, a proposal is now on the table to keep the rate in place at 6.25, which amounts to a tax increase.
