A New York Business Certificate is a document that is required to form a business in the state of New York. It is also known as a Certificate of Authority. This certificate is issued by the Department of State after businesses have met certain requirements such as registering with the New York Department of Taxation and Finance and paying the applicable filing fees. Depending on the type of business, different types of New York Business Certificate may be required. These include a Certificate of Incorporation, a Certificate of Limited Partnership, a Certificate of Assumed Name, a Certificate of Limited Liability Company, and a Certificate of Doing Business As (DBA). The New York Business Certificate serves as proof that the business is legally registered in the state and can be used for a variety of purposes, such as opening a business bank account, entering into contracts, and applying for business licenses.
