Step 1: Name Your Maine LLC

Choosing a company name is the first and most important step of forming an LLC in Maine. Be sure to choose a name that complies with Maine naming requirements and is easily searchable by potential clients.

1. Follow the naming guidelines:

  • Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your professional LLC.
  • Your name must be distinguishable from any other Maine, limited liability company, corporation, limited liability partnership or limited partnership.

For a complete list of naming rules in Maine, check out Maine's Naming Guidelines.

2. Is the name available in Maine? Make sure the name you want isn't already taken by doing a Business Entity Search on the Maine Secretary of State website.

To learn more about searching for a Maine LLC name, read our full guide.

3. Is the URL available? We recommend that you check 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 in order to prevent others from acquiring it.

Step 2: Choose a Registered Agent in Maine

You are required to nominate a Maine registered agent for your Maine LLC.

What is a registered agent? A registered agent is an individual or business entity responsible for receiving important legal documents on behalf of your business. Think of your registered agent as your business's point of contact with the state.

Who can be a registered agent? A registered agent must be a resident of Maine or a corporation, such as a registered agent service, authorized to transact business in Maine. You may elect an individual within the company, including yourself.

If you’re expanding your existing LLC to the state of Maine, you will need to form a foreign LLC.

Step 4: Create a Maine LLC Operating Agreement

In Maine, LLCs are required to have an operating agreement per Revised Statutes Section 1531.1.B of the state's legal code. Maine refers to the operating agreement as the limited liability company agreement.    

What is an operating agreement? An operating agreement is a legal document outlining the ownership and operating procedures of an LLC.

Why are operating agreements important? A comprehensive operating agreement ensures that all business owners are on the same page and reduces the risk of future conflict.

For more information on operating agreements, read our Maine LLC operating agreement guide.

Step 5: Get a Maine LLC EIN

You can get an Employer Identification Number (EIN) from the IRS for free. It is used to identify a business entity and keep track of a business’s tax reporting. It is essentially a Social Security number (SSN) for the company.

Why do I need an EIN? An EIN number is required for the following:

  • To open a business bank account for the company
  • For federal and state tax purposes
  • To hire employees for the company

Where do I get an EIN? An EIN is obtained from the IRS (free of charge) by the business owner after forming the company. This can be done online or by mail.
