Entity Name

Having a creative and smart business name is important but not as important as having a legally correct name.


When you choose a name for your business, you have to make sure the name:

  • meets Maine naming guidelines. 
  • is not already in use by another business in Maine. 


Follow the Maine Naming Guidelines:

  • Your name must include the phrase “limited liability company” or “limited company” or one of their abbreviations (LLC, L.L.C., L.C., LC).
  • Your name cannot include obscene language. 
  • Your name cannot promote abusive or unlawful activity.
  • Your name cannot falsely suggests an association with public institutions.
  • You must get approval from the Maine Bureau of Financial Institutions to include any of the following words in your name: savings, savings bank, bank, banker, banking, trust, trust company, trust and banking company, and credit union (or any plurals or variations).
  • Your name must be distinguishable from any existing business in the state. This includes Maine reserved names. We will help with this step in the search for your business name section below.
  • Low-profit LLC names must include "Low-profit Limited Liability Company, "L3C," or "13c." 


Check Name Availability:

Entity Type

If applicable, you must state if your LLC will be designated as a low-income or professional LLC.

Register Your Domain Name:

We recommend checking to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL to prevent others from acquiring it.

Steps After Your Maine LLC Is Officially Formed

Once you’ve filed your Certificate of Formation, you should take the following steps:

Create an Operating Agreement

Maine LLC Operating Agreement is a legal document that outlines the ownership structure and member roles of your LLC.

In Maine, you aren’t required to have an Operating Agreement to officially form an LLC, but it's still a good idea to have one. You can start your operating agreement before, during, or after you file your Articles of Organization.

Your operating agreement will be kept in your LLC’s private business records; you do not file it with the state.

Use our free Operating Agreement Tool to draft a customized operating agreement for your LLC.

Get an EIN

An Employer Identification Number (EIN) is like a social security number for your LLC. You will need an EIN if you want to hire employees or open business bank accounts.

You can get your EIN for free through the IRS website, via fax, or by mail. If you would like to learn more about EINs and how they can benefit your LLC, read our What is an EIN article.

Open a Business Bank Account

Using dedicated business banking and credit accounts is essential to protect your business' corporate veil. When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued.

Get Licenses and Permits

When you are registering an LLC, you need to determine if your business needs any licenses or permits in order to remain compliant. On the federal level, there are a handful of business activities that require licenses and/or permits.

Brand Your Business

The strongest and most memorable businesses are built on a solid brand. When developing your brand, think about what your business stands for. Customers and clients are looking for companies that have a compelling brand, as much as they are shopping for high-quality products and services.

Creating a logo for your business is vital for increasing brand awareness. You can design your own unique logo using our Free Logo Generator. Our free tool can help you design your own unique logo for your new business idea.
