2. Registering For a Certificate of Authority
If you sell tangible personal property or taxable services in New York you must obtain a Certificate of Authority from the Department of Taxation and Finance.
This certificate authorizes your Business To collect sales tax from customers and is required for physical and certain remote sellers.
Who Needs a Certificate of Authority
Any Business with a physical presence such as a store, office, or warehouse in New York that sells taxable goods or services must register.
Remote sellers without a physical presence must register if their sales into New York exceed $500,000 in the prior four sales tax quarters and they made more than 100 sales of tangible personal property delivered to the state.
How To Create a NY.gov Business Account
Begin by visiting the New York Business Express website and creating a NY.gov Business account.
An Individual NY.gov account is not sufficient; Business Owners must create the separate Business account to access the online Certificate of Authority application.
How To Apply For the Certificate of Authority (Form DTF-17)
Log in to your NY.gov Business account and complete Form DTF-17 with your EIN, business details, NAICS code, and planned start date for taxable sales.
Apply at least 20 days before beginning operations in New York to allow time for processing and receipt of your Certificate.
Processing Time and Receiving Your Certificate
After electronic submission you will receive a confirmation page; print and keep it for your records.
The Department typically mails the Certificate of Authority within about five business days to the business address you provide and you must display it at your place of business.
