A trade name, also known as a trading name, business name, or operating name, is a pseudonym used by companies and other organizations that do not operate under their registered legal name. Registering the trade name with a relevant government body is often required. In a number of countries, the phrase “trading as” (abbreviated to t/a) is used to designate a trade name. In the United States, the phrase “doing business as” (abbreviated to DBA) is used, among others, such as assumed business name or fictitious business name. In Canada, “operating as” (abbreviated to o/a) and “trading as” are used, although “doing business as” is also sometimes used. A company typically uses a trade name to conduct business using a simpler name rather than its formal and often lengthier name. Trade names are also used when a preferred name cannot be registered, often because it may already be in use.
Branding and Operational Flexibility
- Branding: Enables a sole proprietor (e.g., Jane Smith) to market services under a business name (e.g., Jane’s Designs).
- Banking: Required by most financial institutions to open a business bank account or to cash checks made out to a company name.
- Operational Scale: Allows a single LLC or Corporation to operate multiple sub-brands without the cost of forming new legal entities for each.
Legal and Tax Considerations
- No Liability Protection: Filing a DBA does not shield personal assets from business lawsuits or debts; it is an identity tool, not a legal shield.
- No Tax Impact: It does not change your tax status; you use the same Tax ID (SSN or EIN) as your underlying entity.
- No Name Ownership: A DBA generally provides no trademark protection; it merely satisfies the legal requirement to disclose the identity behind a business name.
