How to Form an LLC: Step-by-Step
- 1
Choose Your Maine LLC Name
Select a unique name that includes 'LLC' or 'Limited Liability Company' and isn't already taken in Maine. Search the Maine Secretary of State's business name database to verify availability. Your name can't be misleading about your business activities or imply government affiliation.
How to search Maine's business entity records →
Pro tip: Reserve your name for 120 days by filing a Name Reservation Application with the Maine Secretary of State for $20 if you're not ready to file immediately. - 2
Appoint a Maine Registered Agent
Designate a registered agent with a Maine address who can receive legal documents during business hours. This can be yourself, another person, or a professional service. The agent must have a physical Maine address (not a P.O. Box) and be available during normal business hours.

Pro tip: A professional registered agent service puts its address, not yours, on the registered agent line of the public filing, and accepts legal papers during business hours. - 3
File Certificate of Formation
Submit your Certificate of Formation to the Maine Secretary of State with the $175 filing fee. It is filed on paper, by mail or in person at the Secretary of State's office.
What You File in Maine
In Maine, the formation document is the Certificate of Formation (Form MLLC-6), filed with the Maine Secretary of State, Division of Corporations, UCC and Commissions. The state filing fee is $175. Maine does not take the Certificate of Formation online; it is filed on paper. The state's published processing time: 40 to 55 business days. The form itself requires the LLC's name, the registered agent's name, the organizer's name and the registered agent's consent. Every line of the Certificate of Formation, field by field →
Processing Times
- Online: Corporate filings processing time is 40 - 55 business days. The state doesn't split this by filing channel
- Mail: Not published, Maine Secretary of State states no standard turnaround for mailed filings, and every state that comments says mail is slower than online
- Expedited: $50 for 24-hour expedited filing (next business day), and $100 for Immediate expedited filing (same business day)
Pro tip: Maine does not take the Certificate of Formation online, so print Form MLLC-6 and mail or hand-deliver it with payment to the Corporations Division in Augusta. - 4
Create an Operating Agreement
Draft an operating agreement that outlines ownership percentages, management structure, and operating procedures. This page has not confirmed whether Maine law requires an LLC to have an operating agreement. A written agreement signed by every member is worth having either way: it records who owns what share, who makes decisions and how profits are divided.

Pro tip: An operating agreement prevents disputes between members and can help maintain your LLC's limited liability protection in court. - 5
Obtain Federal EIN Number
Apply for an Employer Identification Number (EIN) from the IRS, which serves as your LLC's tax ID number. Most banks ask for this federal tax ID to open a business bank account, and the IRS requires one if the LLC hires employees, owes certain employment or excise taxes, or is taxed as a partnership or corporation. You can apply online for free directly through the IRS website.

Pro tip: Get your EIN immediately after your Articles are approved - you'll need it for banking and many other business activities. - 6
Open a Business Bank Account
Separate your personal and business finances by opening a dedicated LLC bank account. Bring your Certificate of Formation, EIN letter, and operating agreement to the bank. Maintaining separate accounts matters for preserving your limited liability protection.

Pro tip: Maine's Business Licensing Information Center provides a comprehensive database to help identify exactly which licenses your specific business needs.
This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each Secretary of State publishes for forming an LLC, with the sources this page cites. It cannot tell you what your own filing needs: fees and forms change between our reviews, several occupations cannot use an ordinary LLC at all and must use a professional entity, and your city or county may require a registration of its own. Confirm the current fee and form with the filing office named on this page before you send anything.
