If you are a business using a name other than your personal name or the business name registered with the Maryland secretary of state, you are making use of a "fictitious" or "trade name." Under Maryland law, any business using a trade name must register it with the Department of Assessment and Taxation.
Select a trade name and check if it is available for use. The secretary of state maintains a business name database that you can access to search for your proposed trade name. A trade name must be original, unique and accurate. If your business is a sole proprietorship, your trade name cannot imply that it is a corporation. Furthermore, if the name is already in use as a business name or trade name, you will not be able to use it.
Obtain a "trade name application" for the Maryland State Department of Assessment and Taxation (SDAT). The application is available online or you can pick up a hard copy at the SDAT office.
