  personal property provide to customers. Sales tax vendors that sell tangible personal property in a locality that imposes the paper

  personal property or a service to the customer. Vendors must report and remit the fee on Form ST-100.13, Quarterly Schedule E. 
  For a current listing of the localities that enacted the fee, see Publication 718-B, Paper Carryout Bag Reduction Fee.
