An NYS certificate of authority is the document that companies must apply for to conduct operations in New York state. This typically applies to companies that are already incorporated in a different state. The certificate of authority eliminates the need to incorporate a new business entity, instead establishing the company as a foreign entity in New York state. Doing business in New York without having this certificate can result in fines or other penalties. You may also need the certificate of authority to register for other business licenses and to register with banks and vendors.

When Is a Sales Tax Certificate of Authority Required?

Most businesses that register in New York will also need a sales tax permit. You'll need a certificate of authority to collect sales tax from customers, and you must also register with the New York Department of Taxation and Finance. If you sell tangible property or provide taxable services, such as the maintenance and repair of property, you are considered a vendor and must collect sales tax. This also applies to the following:

  • Those who have a store, warehouse, office, or another place of business in New York and sell tangible, taxable personal property or services to customers in New York.
  • Those who have employees, agents, representatives, or independent contractors who sell tangible, taxable personal property on behalf of your business to customers in New York.
  • Those who use advertising material, such as catalogs in the state, to sell tangible, taxable personal property or services.
  • Those who regularly deliver taxable products to customers in New York state.
  • Those who have a home-based e-commerce business.

Occasional yard sales are not taxable. Tax on sales of cars and homes is paid by the buyer when the title is received.

Does My Online Business Need an NYS Certificate of Authority?

Online businesses may need an NYS Certificate of Authority if they have:

  • A physical presence in New York, such as an office or warehouse.
  • Employees or contractors located in New York.
  • Sales exceeding the state’s economic nexus threshold (over $500,000 in annual sales and 100+ transactions).
  • Regular shipments into New York, making them subject to tax collection laws.

If your online business meets any of these conditions, you must register for a Certificate of Authority to collect and remit sales tax.

How Can Businesses Apply for an NYS Certificate of Authority?

When you register for the certificate of authority, you'll receive a sales tax ID number from the NYS Department of Taxation and Finance.

Renewal and Compliance for an NYS Certificate of Authority

The Certificate of Authority is not a one-time registration. Businesses must ensure they remain compliant by:

  • Renewing the Certificate: Standard certificates expire every three years and require renewal.
  • Filing Timely Sales Tax Returns: Businesses must file monthly, quarterly, or annual returns based on their tax liability.
  • Maintaining Accurate Records: NYS tax authorities may audit businesses, so keeping sales records and tax filings updated is essential.

Businesses that fail to renew their certificate or submit required tax filings may face penalties, including revocation of the Certificate of Authority.
