Sales tax exemptions for the airplane industry would be grounded under legislation filed by Rep. Cory Atkins (D-Concord). “To take a whole industry and exempt a sales tax is preposterous,” said Atkins, who said she had not seen any “numbers” that indicate there would be any job loss by subjecting airplanes to the state’s sales tax. The bill (H 2490) before the Joint Committee on Revenue drew remonstrations from the airplane industry. “Expense is the principal motive for business and owners alike,” said Westport resident and pilot Sean Collins, of the Aircraft Owners and Pilots Association. He said application of the sales tax would “drive aircraft to other states.” Dean Saucier, of the National Business Aviation Association, said carbon emissions “would double” as airplanes housed out-of-state flew into Massachusetts to pick up passengers. “Aviation is very, very mobile,” Saucier said.
