Register a Foreign LLC or Corporation in Maine: $250 Qualification, $150 Annual Report and $90 Withdrawal

If your LLC or corporation was formed in another state and you want to do business in Maine, you need to register with the Maine Secretary of State before you start that work. This guide walks through maine foreign llc registration step by step: what each filing costs, what you need to attach, how the annual report works, and how to withdraw when you are finished.

This article is informational content, not legal or tax advice. Whether you must register, and how Maine taxes your entity, depends on your facts. Talk to a qualified attorney or CPA before you file, especially if you have Maine employees, property, or regular sales here.

Who Must Register in Maine

A foreign entity is an LLC or corporation organized under the laws of another state or country. Under Maine law, a foreign LLC must file its statement of foreign qualification with the Secretary of State before it conducts activities in Maine (31 MRSA 1622). Foreign corporations file an application for authority under 13-C MRSA 123, and foreign nonprofits file under 13-B MRSA 1401.

Maine does not require registration for every out-of-state contact. The statutes (31 MRSA 1623 and 13-C MRSA 1501(2)) list activities that do not count as doing business in Maine, including:

Holding meetings of members, managers, or directors
Maintaining bank accounts
Hiring independent contractors
Accepting orders that are finalized outside Maine
Completing isolated transactions within 30 days

These exceptions are narrow and fact-specific. A business with a Maine office, Maine employees, or recurring Maine customers should assume it needs to register. If you are on the line, ask an attorney before you start work in the state.

Maine Foreign Registration Fees at a Glance

Filing	Who files it	Fee
Statement of foreign qualification (31 MRSA 1622)	Foreign LLC	$250
Application for authority (13-C MRSA 123)	Foreign business corporation	$250
Application for authority (13-B MRSA 1401)	Foreign nonprofit corporation	$45
Annual report (Form MLLC-13 or MBCA-13 style filing)	Foreign LLC or foreign corporation	$150
Annual report	Domestic or foreign nonprofit corporation	$35
Statement of change (31 MRSA 1680)	Foreign LLC	$90, or $35 if only the principal office address changes
Amended application	Foreign business corporation	$70, or $35 for an address-only change
Withdrawal or cancellation	Foreign LLC or foreign corporation	$90
Registered agent change (Form CLKRA-3)	Any LLC or corporation	$35
Assumed name (Form ASUM-5)	Any registered entity	$125
Name reservation (Form MLLC-1, 120 days)	Any LLC name	$20
Maine certificate of existence	Maine record request	$30

Note the annual report figure. A foreign LLC pays $150, not the $85 fee that applies to Maine domestic LLCs. Expedited service is available for an added fee: $50 for 24-hour service and $100 for immediate service, per request. Availability depends on staffing at the time you ask, and the Bureau reports delays when expedited volume is high.

Step 1: Get a Home-State Certificate of Existence

Your Maine application must attach a certificate of good standing, called a certificate of existence, from your home state. Maine requires that certificate to be issued within 90 days of your filing (31 MRSA 1622(2)(H) for LLCs and 13-C MRSA 1503(2) for corporations). Order it from your home state's Secretary of State or equivalent office, and confirm that office's fee and turnaround before you order.

Do not confuse this with Maine's own $30 certificate of existence. That certificate documents a Maine record. It does not replace the home-state certificate you need for your foreign filing.

Step 2: Appoint a Maine Registered Agent

Every Maine LLC and corporation must appoint and continuously maintain a registered agent (called a clerk for business corporations) under the Model Registered Agents Act, Title 5, chapter 6-A. Your agent must consent to serve, and the agent must be one of two types:

Commercial registered agent: a company listed with the Secretary of State and identified by its CRA public number.
Noncommercial registered agent: an individual or business at a physical street address in Maine. A P.O. box does not qualify (5 MRSA 104). Give a separate mailing address if it differs.

Agent changes are filed on Form CLKRA-3 for $35. Many out-of-state owners use a commercial agent because it supplies the required Maine street address and a physical presence for service of process. Compare costs carefully, since commercial agent fees are set by each provider, not by the state.

Step 3: Choose a Compliant Name

Maine LLC names must include "limited liability company," "limited company," "L.L.C.," "LLC," "L.C.," or "LC" (or "L3C" for a low-profit LLC), per 31 MRSA 1508. Check with the Division of Corporations whether your home-state name can be used as is. Search the Secretary of State database at apps3.web.maine.gov/nei-sos-icrs/ICRS before you file. If you need time to prepare the application, you can reserve a name on Form MLLC-1 for $20. The reservation lasts 120 days.

If your home-state name is already in use in Maine, confirm with the Division of Corporations how it handles the conflict before you file. Do not assume the filing will be accepted under the same name.

Step 4: Prepare and File the Application

Maine does not offer online filing of formation documents. Foreign qualification forms are fillable PDFs that you print and either mail or deliver with payment. Find the current forms on the Secretary of State's LLC and corporation forms pages at maine.gov/sos/corporations-commissions. Confirm the payment method on the form instructions before you send anything.

The Secretary of State's corporations and LLC pages state a processing time of 2 to 7 business days for corporate filings (read October 28, 2026; earlier snapshots were far longer), and the figure varies. Treat that range as an estimate and check the current page before you plan around it. If you need faster handling, you can request expedited service as described above.

Before you mail the packet, confirm that you have:

The completed foreign qualification or application for authority
A home-state certificate of existence dated within the last 90 days
The Maine registered agent information, with the agent's consent
The correct filing fee and any expedite fee

Step 5: Check Licenses by Activity, Not by Entity

Maine has no general statewide business license and no general town license. Registering an entity or an assumed name is a filing, not a license. Licensing depends on what your business does:

Municipal ordinances: Cities and towns license named activities under their own ordinances, and fees vary widely by town. Contact the municipal office where you operate.
Health Inspection Program: Licenses eating places. Confirm requirements with the state before you open.
Department of Agriculture, Conservation and Forestry: Licenses food processors.
Department of Professional and Financial Regulation boards: License certain trades. Maine has no HVAC license and no general contractor license, so check the board for your specific trade.

Maine has 16 counties, but they do not license ordinary businesses. The state has 482 organized municipalities: 23 cities, 430 towns, and 29 plantations. To identify the permits that apply to your activity, use the free Business Answers assistant at maine.gov/businessanswers. Confirm any municipal fee with that town directly, since the state does not publish those figures.

Step 6: Register an Assumed Name if You Need One

If your Maine business will operate under a name other than your registered entity name, file a Statement of Intention to do Business under an Assumed Name (Form ASUM-5) with the Secretary of State. The fee is $125. Find the form on the Secretary of State's LLC forms page.

Sole proprietors and general partnerships follow a different path. They file a sworn assumed-name certificate with the clerk of the city or town where the business is carried on (31 MRSA 1). Municipal fees are set locally, so confirm the amount with the clerk.

Step 7: Understand the Tax Picture

Maine has no LLC franchise tax and no separate LLC annual tax. The only recurring state filing charge for a domestic LLC is the $85 annual report. Foreign entities pay the $150 annual report discussed below. Tax treatment depends on how the entity is classified and what it does in Maine:

Sales tax: The general rate is 5.5%. Prepared food and on-premises liquor are taxed at 8%, lodging at 9%, and short-term car rentals at 10%. The list of taxable services is closed, and lawn care, towing, handyman work, and junk removal are not on it. Get a sales tax permit through Maine Revenue Services.
Remote sellers: If your gross sales into Maine exceeded $100,000 in the prior or current year, you must register separately with Maine Revenue Services (36 MRSA 1754-B).
Pass-through LLCs: An LLC is taxed by default as a pass-through, and members report income on Maine individual returns at graduated rates of 5.8% to 7.15%. For tax years beginning on or after January 1, 2026, a 2% surcharge applies to Maine taxable income above $1,000,000 (single), $750,000 (married filing separately), or $1,500,000 (married filing jointly or head of household).
Corporate tax: A corporation, or an LLC that elects corporate treatment, pays Maine corporate income tax at graduated rates from 3.5% to 8.93% (Form 1120ME).

Whether your foreign entity owes Maine income tax depends on its Maine activity and its federal classification. Confirm your obligations with Maine Revenue Services and a CPA, and do not rely on a general rate table to answer that question.

Annual Reports and Deadlines

Annual reports are due June 1 each year. The first report is due between January 1 and June 1 of the year following your registration. Confirm your exact due date in your Secretary of State record. File online through Annual Report Online (InforME) at apps1.web.maine.gov/cgi-bin/online/aro/index.pl.

Foreign LLC: $150
Foreign business corporation: $150
Domestic or foreign nonprofit corporation: $35

Ask the Secretary of State about late-filing consequences before you miss a deadline. Calendar June 1 every year as soon as your registration is complete.

Changing Your Information After Registration

Keep your Maine record current. Update the record when:

Your principal office address changes. A foreign LLC files a statement of change for $90, or $35 if only the principal office address changes.
Your foreign corporation changes its name, purpose, or other authority information. An amended application costs $70, or $35 for an address-only change.
You change your registered agent. File Form CLKRA-3 for $35.

Withdrawing From Maine

If you stop doing business in Maine, file a withdrawal or cancellation with the Secretary of State. The fee is $90 for both foreign LLCs and foreign corporations. Before you file, confirm with the Secretary of State and Maine Revenue Services whether you must also file a final annual report, clear any sales or income tax accounts, or meet other conditions. Keep your records in case Maine asks about the withdrawal later.

Common Mistakes to Avoid

Paying the $85 fee. That is the domestic LLC annual report fee. Foreign LLCs pay $150.
Sending Maine's $30 certificate instead of the home-state certificate. Your filing needs the home-state certificate, dated within 90 days.
Using a P.O. box for the registered agent. Maine requires a physical street address (5 MRSA 104).
Assuming Maine has a general business license. Check licensing by activity and by town.
Waiting too long to register. File before you conduct activities in Maine that go beyond the exceptions listed above.
