Maine LLC filing fee & timeline
To form an LLC in Maine you file your Certificate of Formation with the state and pay the state filing fee of $175. Incofile adds a flat, one-time service fee on top — no monthly charges — and your total is always shown before you pay.
Most Maine LLC filings are prepared and submitted within one business day. State approval time depends on Maine's current processing queue, typically ranging from a few business days to a few weeks, with expedited options available in many states.
Why form an LLC in Maine
Maine is unusual in that LLC formation is filed by mail, not online, and standard processing takes about 10–15 business days plus mail time — so many founders pay for 24-hour or same-day service. The $175 filing fee and $85 annual report are on the higher side, and there is no general state business licence.

How to start an LLC in Maine: step by step
Here is exactly what forming a Maine LLC involves, whether you file it yourself or let Incofile handle the paperwork.
Choose and check your LLC name
Pick a name that includes “LLC” or “Limited Liability Company” and is distinguishable from existing Maine businesses. Check it with our free business name search.
Appoint a registered agent
Name a registered agent with a physical street address in Maine (not a PO box) who can accept legal papers during business hours. The Certificate of Formation confirms that the agent has consented to serve. If you live outside Maine or want privacy, Incofile can act as your agent.
File the Certificate of Formation
Complete Form MLLC-6 and file it with the Secretary of State by mail with the $175 fee. Standard processing is about 10–15 business days plus mail time; 24-hour service costs $50 more and same-day service $100 more.
Create an operating agreement
Maine does not require you to file an operating agreement, but it records who owns the LLC, how profits are shared and how decisions are made. Banks commonly ask for it, and it helps protect your limited liability.
Get an EIN
Apply to the IRS for your Employer Identification Number (EIN). You need it to open a business bank account, hire staff and file federal taxes. The IRS issues it free; non-US owners without an SSN apply by phone, fax or mail, and our Gold package handles it for you.
Register for taxes and local licences
Register with Maine Revenue Services through the Maine Tax Portal for sales tax and withholding if needed. Maine has no state business licence; general licences are handled by your town or city.
File your annual report each year
File the $85 annual report online between 1 January and 1 June every year, starting the year after formation. A late report costs $50 more, and an LLC that does not pay is dissolved after a 60-day notice.
What you need to form an LLC in Maine
- A business name that is available and meets Maine's naming rules (it must include “LLC” or “Limited Liability Company”).
- A registered agent with a physical address in Maine — Incofile can be your agent.
- Certificate of Formation filed with the Maine state office — we prepare and submit these for you.
- An operating agreement and EIN to open a business bank account (included in our Gold and Platinum packages).
- Ongoing compliance — Maine's reports, taxes and registered agent rules (see below). We track the deadlines and remind you.
Operating agreement
An operating agreement sets out who owns the LLC, how profits are split, how decisions are made and what happens if a member leaves. Maine does not ask you to file it with the state, but banks usually want to see it, and without one the state's default rules apply. Incofile includes a customised operating agreement in the Gold and Platinum packages.
EIN (Employer Identification Number)
Your EIN is the federal tax ID for your LLC. You need it to open a business bank account, hire staff and file taxes. The IRS issues it free — online in minutes if you have a Social Security number, or by fax or mail (one to eight weeks) if you don't. Our Gold and Platinum packages include it, and it is also available as a separate service.
This is general information, not legal advice. If you're unsure which structure is right, compare LLC vs S-Corp vs C-Corp.
Maine LLC naming rules
The name must contain “Limited Liability Company” or an abbreviation such as “LLC” or “L.L.C.” and must be distinguishable from every other entity on the Maine register. Check availability with our free business name search.
Keeping your Maine LLC compliant
Annual report
File between 1 January and 1 June every year, starting the year after formation, online for $85. A late report adds a $50 penalty; if the penalty is not paid the Secretary of State issues a notice and dissolves the LLC 60 days later. Reinstatement costs $150 per delinquent year, up to a maximum of $600.
Registered agent
Maine requires either a commercial registered agent listed with the Secretary of State or a noncommercial agent with a physical Maine street address. Incofile can act as your Maine registered agent.
Taxes
Owners pay Maine income tax on their share of profit at 5.8%, 6.75% or 7.15%, with a new 2% surcharge on taxable income above $1 million (single) from tax year 2026. There is no entity-level tax on a pass-through LLC.
Licences
Maine has no state business licence; general licences are issued by towns and cities. Register with Maine Revenue Services for a sales tax account if you sell taxable goods.
Incofile clients get every Maine deadline tracked in their dashboard with email reminders — see registered agent service.
