The New York Application for Registration as a Chain Store is a form that must be completed and submitted to the New York State Department of Taxation and Finance by businesses that operate as chain stores. The form requires applicants to provide information related to the chain store’s business, including its legal name, type of business, and contact information. The form must also be signed by a designated representative of the chain store. There are three types of New York Applications for Registration as a Chain Store: Form AU-11, for changes to previously-filed chain store information; Form AU-11A, for chain stores with five or fewer locations; and Form AU-11B, for chain stores with more than five locations.
