Senate Bill 746 would allow Cabarrus County to adopt a local option sales tax of one-quarter of a cent to support schools. Proceeds can be used for capital projects and the county cannot divide proceeds to districts. The author of the bill is Sen. Paul Newton, a former Duke Power Co. president who supports charter schools. A similar bill reportedly is on the drawing board for Mecklenburg County where two municipalities want to establish charter schools independent of the CMS system. The bill requires county commissioners to call for a public referendum. The tax would not be levied on prepared food in restaurants etc.
