Register as a sales tax vendor
Every person who sells taxable tangible personal property or taxable services (even if you make sales from your home) must register with the Tax Department though New York Business Express before beginning business. If you aren't sure whether you need to register for sales tax purposes, see Tax Bulletins Do I Need to Register for Sales Tax? (TB-ST-175) and Sales from Your Home (TB-ST-807).
