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 cannot be misleading about your business activities or imply government affiliation.
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: Using a professional registered agent service protects your privacy and ensures you never miss important legal documents, even when traveling. - 3
File Articles of Organization
Submit your Articles of Organization to the Maine Secretary of State with the $175 filing fee. Include your LLC name, registered agent information, organizer details, and management structure. You can file online, by mail, or in person at the Secretary of State's office.
Pro tip: Filing online is fastest and allows you to track your application status in real-time through the Maine Secretary of State portal. - 4
Create an Operating Agreement
Draft an operating agreement that outlines ownership percentages, management structure, and operating procedures. While Maine doesn't require this document, it's essential for multi-member LLCs and provides important legal protections even for single-member LLCs.
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. This is required for opening business bank accounts, filing taxes, and hiring employees. 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 Articles of Organization, EIN letter, and operating agreement to the bank. Maintaining separate accounts is crucial for preserving your limited liability protection.
Pro tip: Shop around for business banking options - many Maine credit unions and community banks offer competitive rates and lower fees than national banks. - 7
Obtain Required Business Licenses
Research and obtain any licenses or permits required for your specific business type in Maine. Requirements vary by industry and location. Check with both state agencies and your local city or town government for applicable licenses.
Pro tip: Maine's Business Licensing Information Center provides a comprehensive database to help identify exactly which licenses your specific business needs.
