Commission Chairman Mike Berg is calling for a full millage rate rollback that, if approved, would be the county's first tax reduction in 12 years. "It's my hope that you will approve a 7.8 millage rate so that the taxpayers can get a reduction on property tax and having sales tax kind of take up that difference, much like the fair tax that's called for by Republicans today," he told his fellow commissioners last week. Berg said estimated sales tax revenue from the two new major retail developments on Ga. 400 and Dawson Forest Road has paved the way for his proposal to lower the county's portion of the millage rate.
