Georgia state representatives passed a bill this week that would ban tax collection from airport vendors, a move that some Clayton County officials say would cost the county an estimated $13 million in revenues. House Bill 399, which passed in the House 111-56, now goes to the state senate. If it becomes law, the bill would prevent Clayton from collecting taxes from businesses that have leases at Atlanta Hartsfield-Jackson International Airport. The bill’s passage barely beat the General Assembly’s “Crossover Day” deadline to get legislation passed in at least one chamber. Several members of the Clayton County Legislative Delegation, along with the county NAACP, have opposed the bill.
