Who needs to register for a Maine Assumed Business Name?

The requirements and need to register for a DBA are found in Maine State Statute 31 MRSA§21 and vary depending on the type of business entity.

Sole proprietorships and general partnerships are the most common business structures to register for a Maine DBA. By default, the name of a sole proprietorship and general partnership is the owner(s) legal name, but if the small business owner wants to operate under a specific name, they will need to complete the Assumed Name registration. 

For example, if Amy Smith starts a house cleaning business but doesn’t operate with a specific business name, she doesn’t have to register.  If Amy decides to name her business Amy’s House Cleaning Service, she will need to register.

A corporation and Limited Liability Company won’t typically register for a Maine DBA since a unique entity name is created during the entity formation process. However, some will want to register for a DBA if they have another business or brand name they want to operate in addition to the legal name of the business. This can allow multiple businesses to operate with the liability protection of a Maine corporation or Limited Liability Company without having to form another entity.

Maine DBA FAQs

How much does a DBA cost in Maine?

The fee to register an Assumed Name for a sole proprietor and general partnership varies by town and county, but expect the filing fee to be between $10 and $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.

Are there any naming restrictions when filing a Maine DBA?

In addition to names being unique, DBAs can’t be registered using words related to banking, trust companies, or credit unions unless the business is licensed to provide those services. Names also can’t refer to unlawful activity or contain obscene language.

A DBA can’t use a business entity suffix that is different from the type of entity. For example, a sole proprietorship can’t use LLC or corporation in its name.

Last, words that potentially refer to your business as a government agency (FBI, Treasury, State Department) can’t be used.

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.
