 The distinction between CBAs and IBAs is important when determining state tax exemption. All GSA SmartPay CBAs should be exempt from state taxes. In addition, with a CBA, the federal government accepts liability for charges made by an authorized card/account holder, but is not liable for any unauthorized use. Unauthorized use means the use of an account by a person, other than the card/account holder, who does not have actual, implied or apparent authority for such use and from which the card/account holder receives no benefit. When the CBA has been used by an authorized card/account holder to make an unauthorized purchase, the Government is liable for the charge and the agency is responsible for taking appropriate action against the card/account holder.
