Forming an LLC in Maine takes 5 steps: choose and check your business name, appoint a Registered Agent with a physical Maine address, file a Certificate of Formation by mail (Maine has no online formation filing), draft an operating agreement, and get an Employer Identification Number (EIN) from the IRS. The state filing fee is $175.
If your business operates in Maine, a Maine LLC gives you personal liability protection and pass-through taxation without the corporate formalities of a corporation — and the state keeps entity-level costs simple: no franchise tax, no annual LLC tax, just an $85 annual report. Maine’s 5.5% sales tax is uniform statewide with no local add-ons, and its formation filing is unusually private: the Certificate of Formation doesn’t list members or managers at all.
The trade-off is speed and paperwork: Maine is one of the last states with no online LLC formation — the Certificate of Formation goes in by mail or hand delivery, and the standard queue currently runs 40-55 business days. Most filers pay the $50 expedite for next-business-day processing (or $100 for same-day), which turns one of the slowest states into one of the fastest for a modest fee.
Unlike some states, Maine doesn’t require you to reserve your name before filing — you simply claim it when you file your Certificate of Formation. If you’re not ready to file yet, you can optionally reserve a name (Form MLLC-1, by mail). The fee is $20, and the reservation holds your name for 120 days; it can’t be renewed, so time it against Maine’s processing queue.
Your LLC name must be distinguishable from every entity, reserved name, and registered mark on record with the Maine Secretary of State, and must include a designator like “Limited Liability Company,” “Limited Company,” “LLC,” “L.L.C.,” “LC,” or “L.C.” With a 40-55 day standard queue, a name rejection costs months — check the state’s corporate name search carefully before you file.
Every Maine LLC must have a registered agent — a person or entity designated to receive legal notices and government documents on behalf of the business. The agent must have a physical street address in Maine (a P.O. box doesn’t count) and be available during regular business hours. Maine formally distinguishes commercial registered agents (listed with the state under a CRA number) from noncommercial agents (listed by name and address).
You can serve as your own registered agent if you have a physical Maine address and can be there during business hours. Many business owners use a professional registered agent service instead — it keeps your personal address off public records and ensures someone is always available to receive documents.
The Certificate of Formation (Form MLLC-6) is the document that legally creates your Maine LLC. You file it with the Secretary of State’s Bureau of Corporations in Augusta — by mail or hand delivery only, since Maine has no online formation filing. Standard processing is currently 40-55 business days, so most filers add expedited service: $50 extra for 24-hour processing or $100 for same-day.
The Certificate is unusually minimal: your LLC’s name, its designation as a low-profit LLC or professional LLC if applicable, the filing’s effective date, and your registered agent — a commercial agent’s CRA number, or a noncommercial agent’s name and Maine street address. Members and managers aren’t listed, so ownership stays off the public record at formation. The state filing fee is $175.
Maine doesn’t require you to file an operating agreement with the state, but you should have one — and in Maine it carries extra weight, since the Certificate of Formation names no members or managers, making the agreement the primary written proof of who owns the company. It defines how your LLC is managed: who owns what, how profits are distributed, and how decisions get made. Without one, Maine’s default LLC statutes fill in the gaps.
Your operating agreement should specify whether the LLC is member-managed or manager-managed. In a member-managed LLC, all owners share day-to-day authority. In a manager-managed LLC, a designated manager handles operations while other members retain economic rights. A written agreement is the version that holds up when disputes arise.
An Employer Identification Number (EIN) is a 9-digit federal tax ID issued by the IRS. Your Maine LLC needs one to open a business bank account, hire employees, and file federal taxes. Applying online at irs.gov is free and issues your EIN immediately after you complete the application.
To use the IRS online application, the responsible party must have a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), and the business must have its principal place of business in the United States. The IRS does not charge a fee for issuing an EIN.
Maine LLCs file one report with the Secretary of State: an annual report due June 1 each year, starting the June after formation — so an LLC formed late in the year owes its first report within months. It costs $85 and, in a reversal of the formation process, is filed online. There’s no initial report, no franchise tax, and no annual LLC tax.
Maine has no general state business license, but if you sell taxable goods or services you’ll need to register (free) with Maine Revenue Services through the Maine Tax Portal to collect the 5.5% sales tax. The annual report deadline has real teeth: a $50 late fee lands automatically on June 2, and continued non-filing leads to administrative dissolution 60 days after the state’s notice — reinstatement then costs $150 plus every missed report and its late fees.
The required Maine state fee is $175 to file the Certificate of Formation with the Secretary of State. Most filers also add expedited processing — $50 for 24-hour or $100 for same-day service — because the standard queue currently runs 40-55 business days. The annual report is $85, and reserving your name before filing is optional at $20. There’s no additional state fee to get your EIN; the IRS issues EINs for free.
Yes. Maine allows a single person to form and own an LLC – this is called a single-member LLC. You can complete Form MLLC-6 yourself without an attorney — just note it must be filed by mail or in person, since Maine has no online formation filing. You’ll still need a registered agent with a physical Maine address, but that can be yourself if you qualify.
No. Maine charges a $175 Certificate of Formation fee – that’s a required state fee you can’t avoid. What you can avoid is paying extra for formation help. We handle your Maine LLC filing for $1; you only pay the required state fees.
Yes. Every Maine LLC files an $85 annual report by June 1 each year, starting the calendar year after formation, and it’s filed online — the one part of Maine’s process that is. Miss the deadline and a $50 late fee applies automatically from June 2; keep not filing and the state can administratively dissolve your LLC 60 days after sending notice. Reinstatement costs $150 plus all missed reports and accrued late fees.
Yes, every Maine LLC is required to have a registered agent. A registered agent is a person or entity that receives legal notices and official government documents on behalf of your LLC. The agent must have a physical street address in Maine — not a P.O. box — and be available during regular business hours. You can serve as your own registered agent or use a professional (commercial) registered agent service.
The mistakes that come up most often are hunting for an online formation portal that doesn’t exist — Maine formation is mail or in-person only — and budgeting for the outdated 2-week processing time many guides still quote when the posted queue is 40-55 business days; if timing matters, the $50-$100 expedite is nearly mandatory. Others include missing the June 1 annual report (the $50 late fee is automatic, and the first report can come due just months after forming), using a P.O. box for the registered agent, and skipping the free Maine Revenue Services registration before collecting the 5.5% sales tax.
Standard processing is currently 40-55 business days — Maine files on paper and the queue is long. The fix is cheap: add $50 for 24-hour processing or $100 for same-day service when you file. With expedite, Maine turns around formations as fast as almost any state; without it, plan on roughly two to three months.
