What is a DBA?

A DBA, also known as “Doing Business As,” Trade Name, Assumed Name, or Fictitious Name, is a name used by a business that is different from the legal name of the business.   This name is often referred to as a Trade Name in Maryland.

When a business wants to operate under a name other than their legal name, the state of Maryland, like most states, requires the business to register their business name.  The registration requirement was designed to protect consumers from business owners hiding anonymously behind the name of a business.

What is a DBA good for?

A DBA is required for many businesses in order to legally operate and provides information on the people operating a business.  In addition to the legal requirement, a DBA offers other benefits such as proving the existence of a business, opening a bank account under a business name, registering a merchant account to accept credit cards, and others.

Who needs to register for a Maryland DBA?

The requirements and need to register for a Trade Name vary, depending on the type of business entity. 

Sole proprietorships and general partnerships are the most common entities to register for a DBA. 

The legal name of a sole proprietor or partnership can be the owner’s full first and last name, which can be used without registering.  For example, if Mike Smith starts a business cleaning houses but doesn’t use a business name, he doesn’t have to register.  If Mike decides to name his business Mike’s Home Cleaners, then he will need to register. 

Corporations and Limited Liability Companies won’t typically register a fictitious name since a unique entity name is created during the formation process.  Some will file for a DBA if they have another business they want to operate under their corporate/LLC umbrella to keep the liability protection without forming another entity.

Name Restrictions

DBAs can’t be registered using words that are related to banking or insurance with words such as bank, banker, savings, trust, credit union, and insurance unless the business is licensed to provide those services.  

Trade Names can’t use entity designators, which are words that designate a business entity such as Corporation, Inc., Corp, LLC, Limited Liability Company, etc.

Last businesses performing home improvement services must contact the Maryland Home Improvement Commission to ensure a specific name is available

Can someone steal my business name?

While registering your Trade Name will keep someone else from registering the exact same name in Maryland, it does very little from someone else operating a business under that name in other states. If stopping others from using your business name is important, you can protect it through a trademark.

Does a DBA need an EIN?

An EIN or Employer Identification Number is a unique nine-digit number that some businesses will register for through the Internal Revenue Department (IRS). An EIN is required for partnerships, corporations, multi-member LLCs, or any business that has employees.

Sole proprietorships and single-member LLCs without employees can use the owner’s social security number to identify the business.

There is no cost to get an EIN when registering directly from the IRS.
