Maine LP
The Basics of a Maine LP
What is a limited partnership?
A limited partnership is a business owned by two kinds of partner. General partners run the operation and are personally liable for its debts. Limited partners contribute capital, share in profits, and stay out of management, risking only what they put in. A Maine LP must always have at least one of each.
What law governs Maine LPs?
Maine limited partnerships operate under the Maine Revised Uniform Limited Partnership Act, in Title 31 of the Maine Revised Statutes. That Act defines how an LP is formed, the rights of each class of partner, and the default rules that apply when the partnership agreement is silent.
How is an LP different from an LLC or an LLP?
An LLC gives all its members liability protection and flexible management — it's the general-purpose small business entity. An LLP is a general partnership where all partners get a liability shield, common among professional firms. An LP is different: it deliberately splits owners into managing, personally-liable general partners and passive, protected limited partners. Choose an LP when management and money are meant to sit in different hands.
Who should use a limited partnership?
LPs fit investment vehicles, real estate ventures, funds, and family estate planning — situations where a sponsor or family principal wants control while raising capital from investors who want returns without responsibility. If everyone intends to work in the business and wants protection, an LLC or LLP is usually the better fit.
Forming Your Maine LP
What document forms a Maine LP?
The Certificate of Limited Partnership, filed with the Maine Secretary of State, Bureau of Corporations, Elections and Commissions. The partnership legally exists only once the state accepts and files it.
Can I file online?
No. Maine formation filings are mail-only. You prepare and sign the certificate and mail it to the Bureau in Augusta. Maine's online systems handle the name search and the annual report, but not formation.
Are my limited partners named in the public filing?
No. The Certificate of Limited Partnership lists the general partner(s) and basic partnership information, but not the limited partners, their contributions, or the economic terms. Those stay private in the partnership agreement.
Do I need to live in Maine?
No. There's no residency requirement for general or limited partners. The only in-state requirement is a registered agent with a physical Maine street address.
Partners, Liability, and Governance
Are limited partners really protected from liability?
Yes, as long as they stay passive. A limited partner risks only their contribution — unless they take on management and control of the business, which can strip the protection and expose them like a general partner. Maine's Act lists safe-harbor activities (voting on major matters, consulting, serving as an employee or contractor) that don't cross that line.
Can the general partner be a company?
Yes, and it's a common move. Making an LLC or corporation the general partner keeps the unlimited liability from reaching any individual person. It's worth structuring with an attorney before you file.
Do I need a limited partnership agreement?
Maine doesn't require you to file one, but you shouldn't operate without it. The agreement defines who's a general versus limited partner, how profits and losses are allocated, what authority the general partner has, and what rights limited partners hold. Without it, Maine's statutory defaults govern — and they often don't match the partners' intent.
Who can bind the partnership in contracts?
Generally the general partner, acting within the authority the agreement grants. Limited partners typically can't bind the partnership, and if they try to act like managers they risk their liability shield.
Taxes, Fees, and Compliance
How is a Maine LP taxed?
As a pass-through by default. The partnership files a federal informational return (Form 1065) and issues a Schedule K-1 to each partner, who reports their share on their own return. Maine follows pass-through treatment at the state level, so there's no entity-level income tax under the default rules.
Does an LP need an EIN?
Yes. Because an LP always has multiple partners and files a partnership return, it needs an EIN. You get one free directly from the IRS, and the online application issues it immediately.
When is the annual report due?
June 1 each year, filed through Maine's online annual report system. It keeps the partnership in good standing and updates registered agent and address information. Miss it and the state can administratively dissolve the LP after the grace period.
What are the state fees to expect?
There's a state fee to file the Certificate of Limited Partnership and a separate annual report fee each year. Maine offers expedited processing for an added fee if you're on a deadline. Our receipt card shows the exact amounts we collect before you pay — what's displayed is what's charged.
Changes, Foreign LPs, and Ending the Partnership
How do I change my registered agent?
File a change of registered agent with the Secretary of State, listing the new agent's name, physical Maine address, and consent. Keep the record continuous — get the new agent on file before the old one lapses.
My LP was formed elsewhere. Can it operate in Maine?
Yes, but you must register it as a foreign LP if you'll transact business in Maine. You file an application for authority, appoint a Maine registered agent, and usually provide a certificate of good standing from your home state. Operating without registering can bar you from Maine courts and trigger penalties.
How do I dissolve a Maine LP?
Wind up the business — settle debts, distribute remaining assets to partners per the agreement — and file the appropriate certificate of cancellation or dissolution with the Secretary of State so the LP is formally closed on the record. Filing the closure also stops future annual report obligations.
What if I just stop filing annual reports?
Don't. Letting reports lapse leads to administrative dissolution, which leaves the entity in a messy limbo, can expose the general partner, and requires reinstatement or cleanup to resolve. Formally dissolving is the clean way to end an LP you no longer need.
Frequently asked questions
Is a Maine LP the same as a general partnership?
No. A general partnership has only general partners, all personally liable, and needs no state formation filing. A limited partnership is a formal entity created by filing a Certificate of Limited Partnership, and it has both general partners (liable) and limited partners (protected, passive).
Can a single person own a Maine LP?
Not really — an LP requires at least one general partner and at least one limited partner, so you need at least two distinct roles. One person can't be both the sole general and sole limited partner of the same LP. If you want a single-owner entity, a single-member LLC is the usual choice.
How long does formation take in Maine?
Because Maine formation is mail-only, plan for standard mail processing in each direction. Expedited handling is available for an added state fee. The LP exists only once the Secretary of State files the accepted certificate.
Do limited partners get a say in decisions?
Within limits. Limited partners can vote on major, defined matters — like amending the agreement or admitting a new partner — without losing their protection, but they can't run day-to-day operations. The agreement spells out exactly which decisions require their consent.
Does Mainstay Filing give legal or tax advice?
No. We're a filing and compliance service. We prepare and file your state paperwork and act as your registered agent, but we don't draft partnership agreements or advise on structure and taxes. For those, work with an attorney and a CPA.
