6-Step Checklist to Register Your Maine LLC (2026)
Choose a Unique Name for Your Maine LLC
Your entity name must include 'Limited Liability Company', 'LLC', or 'L.L.C.' and cannot conflict with existing active corporations in the Maine Secretary of State database.
Appoint a Registered Agent (US Street Address)
You must designate a registered agent with a physical street address in Maine to receive service of process and official legal correspondence during standard business hours. Non-resident and international founders can use a commercial registered agent service for ~$49/year.
File the Maine Articles of Organization
Submit the Articles of Organization (or Certificate of Formation) online to the Secretary of State along with the statutory $81 state filing fee.
Draft an Operating Agreement
An internal legal document establishing ownership percentages, member voting rights, profit distributions, and liability provisions. While not filed with the state, banks require this to open accounts.
Obtain a Federal EIN from the IRS (Even Without SSN)
An Employer Identification Number (EIN) is required for federal tax reporting, hiring, and opening a US business bank account. US residents can apply online in 15 minutes; non-US/UK residents can obtain an EIN via Form SS-4 fax submission without an SSN or ITIN.
Open a US Business Bank Account & File FinCEN BOI
Set up a dedicated US business bank account (e.g. Mercury Bank, Relay, or Chase) and submit your mandatory Beneficial Ownership Information (BOI) report to FinCEN within statutory deadlines.
