About

Taxation and Finance, Department of State
If you sell taxable tangible personal property or taxable services in New York State (even if you make sales from your home), you must register with the NYS Department of Taxation and Finance in order to obtain a Certificate of Authority before opening your business. The Certificate of Authority gives you the right to collect sales tax on your taxable sales and to issue and accept most New York State sales tax exemption certificates.

"Tangible personal property" means any kind of physical personal property that has a material existence and is perceptible to the human senses (something you can see and touch). Sales of tangible personal property and certain services are subject to sales tax when delivered in New York State. Taxable goods and services include:

  • tangible personal property (unless specifically exempt);
  • gas, electricity, refrigeration and steam, and telephone service;
  • selected services;
  • food and beverages sold by restaurants, taverns, and caterers;
  • hotel occupancy; and
  • certain admission charges and dues
For more detailed information about what sales are subject to tax, see Tax Bulletin Quick Reference Guide for Taxable and Exempt Property and Services (TB-ST-740).
