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.

When a business wants to operate under a name other than their legal name, the state of Maine, 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 Maine 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 John Smith starts a business repairing computers but doesn’t use a business name, he doesn’t have to register.  If John decides to name his business John’s Computer Repair, 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.

Maine DBA Registration Form

Sole proprietorships and partnerships will obtain a form from the Municipal or Town Clerk. Most have the form on their website, while others are available at the Clerks office.

Corporations file Form MBCA-5, and LLCs file Form MLLC-5A

How much does a DBA cost in Maine?

The fee to register an Assumed Name for sole proprietorships and partnerships varies by town and county, but expect $10-$20.  This is a one-time fee.

The filing fee to register an Assumed Name for domestic corporations and LLCs is $125.  On the same form, there is the option to register a Fictitious Name.  Fictitious Names are only for foreign entities, which refer to entities formed in another state.  Names must be renewed every 10 years.

Can someone steal my business name?

While registering your Trade Name will keep someone else from registering the exact same name in Maine, 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.
