Choosing and forming the right entity is the first legal decision most Massachusetts businesses make, and it shapes everything that follows: who is personally liable, how profits are taxed, what has to be filed with the Secretary of the Commonwealth every year, and how easily the owners can bring in investors or exit later. A Massachusetts entity formation attorney helps founders compare a limited liability company, a business corporation and the partnership forms against the specific statutes that govern each one, and then complete the filings correctly the first time. Holmes Law is the practice of Michael Holmes, an attorney admitted in Massachusetts and five other states, and it helps owners of small and closely held businesses form and organize Massachusetts entities remotely.
This page walks through the Massachusetts statutes that govern each entity type, the filings and fees the Corporations Division charges, the resident agent requirement, professional entities, registering an out-of-state company to do business in Massachusetts, and the state tax rules that often decide the choice. It sits under the Massachusetts business law practice page. It is general information rather than advice for a particular business, and tax treatment should always be confirmed with the company’s accountant.
The Massachusetts Entity Statutes
Massachusetts has a separate chapter of the General Laws for each major form of business organization. Knowing which chapter governs is more than a technicality, because each statute supplies default rules that apply whenever the owners’ own documents are silent.
- Limited liability companies are governed by the Massachusetts Limited Liability Company Act, G.L. c. 156C.
- Business corporations are governed by the Massachusetts Business Corporation Act, G.L. c. 156D, which took effect in 2004 and is based largely on the Model Business Corporation Act.
- Professional corporations are governed by G.L. c. 156A, which layers licensing requirements on top of the corporation statute.
- General partnerships and limited liability partnerships are governed by G.L. c. 108A, Massachusetts’s version of the original Uniform Partnership Act.
- Limited partnerships are governed by G.L. c. 109.
- Business trusts, sometimes called Massachusetts business trusts or voluntary associations, are governed by G.L. c. 182.
Each of these has a place, but for most new closely held businesses the real choice is between an LLC and a corporation, with the partnership forms reserved for specific situations such as professional firms or investment funds.
Massachusetts Entity Formation Attorney: LLC or Corporation?
The Limited Liability Company
An LLC formed under c. 156C gives its members limited liability for company debts, flexible management and, by default, partnership tax treatment under federal law when it has two or more members, or disregarded-entity treatment when it has one. The Massachusetts act is highly deferential to the operating agreement. Section 24 provides that management is vested in the members unless the operating agreement designates one or more managers, and section 29 allocates profits and losses by the agreed value of each member’s contributions unless the operating agreement says otherwise. Section 63(b) allows the operating agreement to expand or restrict the duties of members and managers. That flexibility is the main reason owners choose an LLC, and it is also why an LLC without a written operating agreement is a missed opportunity.
The Business Corporation
A corporation formed under c. 156D has a more fixed structure: shareholders elect directors, directors appoint officers, and the statute prescribes procedures for meetings, votes and distributions. Massachusetts is unusual in one respect. Section 8.40 requires every Massachusetts corporation to have a president, a treasurer and a secretary, although one person may hold more than one office. Corporations remain the natural choice for companies expecting to raise venture capital, issue stock options, or eventually go public, and they are the default structure for businesses planning an S election. A corporation can also be tailored through a shareholder agreement under c. 156D, § 7.32, which is discussed on the page about Massachusetts operating and shareholder agreements.
Partnerships and Business Trusts
A general partnership needs no filing at all; two or more people carrying on a business for profit as co-owners form one under c. 108A whether they intend to or not, and each partner is personally liable for partnership obligations. A limited liability partnership registers with the Secretary and shields partners from many partnership liabilities, which is why it is used by some professional firms. Limited partnerships, which require at least one general partner with unlimited liability, are now used mostly for investment vehicles and family holding structures. The Massachusetts business trust under c. 182 has a long history in the Commonwealth, particularly for real estate and investment funds, but for an operating business it has largely been displaced by the LLC.
Does Massachusetts Allow Series LLCs?
No. Chapter 156C contains no provision for series LLCs, the structure some states use to create internally segregated series of assets and liabilities under one company. Massachusetts owners who want to separate risk, for example by holding several rental properties apart from one another, generally form a separate LLC for each asset, sometimes under a common holding company. A series LLC formed in another state and doing business in Massachusetts raises unsettled questions about whether a Massachusetts court would honor the internal liability shields, which is a reason for caution.
Forming a Massachusetts LLC
A Massachusetts LLC is formed by filing a certificate of organization with the Corporations Division of the Secretary of the Commonwealth under c. 156C, § 12. The certificate must state the company’s name, the address of its office in the Commonwealth, the name and address of its resident agent, the general character of its business, the names of any managers, and the names of persons authorized to execute documents filed with the Corporations Division. It may also name the persons authorized to execute, acknowledge and deliver recordable instruments affecting real property, which is a practical detail worth getting right if the LLC will buy or sell real estate, because title examiners and closing attorneys will look for it.
The Corporations Division’s fee schedule lists a filing fee of $500 for an LLC certificate of organization. The name must include “limited liability company,” “limited company,” or an accepted abbreviation, and must be distinguishable from names already on the Secretary’s records. The company exists when the certificate is filed, or on a later date stated in it.
The $500 Annual Report
The cost that surprises many Massachusetts LLC owners is the annual report. Section 12 requires every domestic LLC to file an annual report, and the fee is $500 each year, the same as the formation fee. That is considerably higher than the annual report fee for a business corporation, which the Corporations Division lists at $125, or $100 if filed electronically. For a small business with modest income, the difference is a real, recurring cost that belongs in the entity-choice analysis, alongside the tax factors discussed below. An LLC that fails to file annual reports can be administratively dissolved under c. 156C, § 70, which can create problems with contracts, bank accounts, litigation and real estate titles until the company is reinstated.
Forming a Massachusetts Corporation
A Massachusetts business corporation is formed by filing articles of organization under c. 156D, § 2.02. The articles state the corporate name, the classes and number of authorized shares and, if there is more than one class, their preferences, limitations and relative rights. They may also include optional provisions, and one worth considering is a clause under § 2.02(b)(4) limiting or eliminating directors’ personal liability for monetary damages for breach of fiduciary duty, within the limits the statute allows. The Corporations Division lists a minimum fee of $275 for articles authorizing up to 275,000 shares, with higher fees for larger authorizations.
After filing, the corporation should adopt bylaws, elect directors, appoint the required officers, issue shares with appropriate legends, and obtain an EIN. Corporations must file an annual report with the Secretary, and the fee structure noted above makes that ongoing cost modest. Organizational minutes and a clean stock ledger matter more than they seem at formation: they are the first documents a buyer, lender or investor asks for, and gaps in them are a common source of delay in later transactions.
Resident Agent and Registered Office
Every Massachusetts LLC must designate a resident agent under c. 156C, § 5, and every corporation must maintain a registered agent and office. The agent can be an individual who lives in Massachusetts or an entity authorized to act as an agent, and the agent’s written consent is filed with the certificate. The resident agent receives service of process, so the practical requirement is someone reliable who will forward lawsuit papers and state notices promptly. Owners who move out of state or who want to keep a home address off the public record often use a commercial resident agent. When the agent or its address changes, the company files a certificate of change under § 5A so the Secretary’s records stay current.
Professional Entities
Licensed professionals such as physicians, dentists, accountants, engineers and attorneys cannot simply form an ordinary corporation to deliver their services. Massachusetts permits professional corporations under c. 156A, which limits share ownership to licensed individuals and ties the corporation to the rules of the relevant licensing board. Chapter 156C also allows LLCs to render professional services, with requirements that the members and managers providing those services be properly licensed and that the licensing board’s standards be satisfied. Neither form protects a professional from liability for his or her own malpractice; the liability shield covers business debts and the acts of other owners, not the individual’s own professional conduct. Some professions also have their own ownership rules, so the licensing board’s regulations should be checked before choosing between a professional corporation and a professional LLC.
Registering an Out-of-State Company in Massachusetts
A company formed in another state that transacts business in Massachusetts must register with the Secretary. A foreign LLC registers under c. 156C, § 48, and the Corporations Division lists a $500 fee, with the same $500 annual report obligation as a domestic LLC. A foreign corporation registers under c. 156D, § 15.01, for which the listed fee is $400. Failing to register when required exposes the company to penalties under c. 156C, § 54 or the corresponding corporation provisions and can prevent the company from bringing suit in Massachusetts courts until it registers.
A common question is whether to form in Delaware and register in Massachusetts or simply form in Massachusetts. For a company that operates only in Massachusetts and does not expect outside institutional investment, forming a Delaware entity usually means paying fees and maintaining filings in two states for little practical benefit. For a company planning a venture capital raise, investors often prefer Delaware. The decision depends on the business plan rather than on any general rule.
Massachusetts Taxes on Entities
State taxes are often the deciding factor between an LLC and a corporation in Massachusetts, and the Department of Revenue treats the forms quite differently.
Corporate Excise
A Massachusetts C corporation pays the corporate excise under G.L. c. 63, which has two measures: an income measure, which the Commonwealth’s tax expenditure budget describes as 8.00 percent of net income apportioned to Massachusetts, and a non-income measure based on tangible property or net worth, at $2.60 per $1,000. The minimum excise is $456 per year, so even a corporation with no income owes something.
S Corporations and the Entity-Level Tax
Massachusetts generally follows the federal S election, so an S corporation’s income passes through to the shareholders’ Massachusetts returns. But Massachusetts also imposes an entity-level tax on larger S corporations. According to the Commonwealth’s published tax expenditure budget, S corporations with total receipts of $6 million or more but less than $9 million pay an income-measure rate of 2.00 percent, and those with total receipts of $9 million or more pay 3.00 percent, in addition to the non-income measure and the minimum excise that apply to all S corporations. Smaller S corporations still owe the minimum excise. An LLC taxed as a partnership is not subject to the corporate excise at all, which is one reason many small Massachusetts businesses choose the LLC, while others choose an LLC and then elect S corporation treatment to manage self-employment taxes. That election brings the S corporation excise rules into play.
Pass-Through Income and the Surtax
Income from an LLC or S corporation flows to the owners’ personal Massachusetts returns, where it is taxed at the flat personal income tax rate. Since 2023, Massachusetts has also imposed an additional 4 percent surtax on taxable income above an annually indexed threshold of roughly $1 million, adopted by constitutional amendment. Business owners who expect a large sale or an unusually profitable year should plan with that surtax in mind, because a single liquidity event can push income above the threshold. The interplay between these taxes and an entity choice is fact-specific and should be modeled with a CPA before filing.
Common Formation Mistakes
- Operating without a written operating agreement or bylaws and relying entirely on the statutory defaults.
- Forgetting the $500 LLC annual report until the company is administratively dissolved.
- Titling assets, leases or bank accounts in an owner’s personal name rather than the entity’s name.
- Omitting the persons authorized to sign real estate instruments from an LLC certificate that will hold property.
- Issuing shares or membership interests to cofounders without vesting or transfer restrictions.
- Transacting business in Massachusetts through an out-of-state entity that was never registered.
- Making an S election without considering the Massachusetts entity-level tax once receipts grow.
Many of these are simple to prevent at formation and expensive to fix later, particularly once a dispute or a sale is underway.
How Formation Fits With Estate and Succession Planning
An entity is also an estate planning tool. Membership interests or shares can be held by a revocable trust so they pass without probate, and transfer restrictions can be drafted to permit transfers to family trusts while blocking transfers to outsiders. For owners whose estates may exceed the Massachusetts estate tax threshold, closely held entities can support lifetime gifting strategies. Those issues are coordinated with the owners’ plans through the Massachusetts estate planning practice, and the question of what happens to an owner’s interest at death or departure is addressed on the page about Massachusetts buy-sell agreements.
Frequently Asked Questions
How much does it cost to form an LLC in Massachusetts?
The Corporations Division lists a $500 filing fee for a certificate of organization and a $500 fee for each annual report. There may also be costs for a commercial resident agent, an EIN is free from the IRS, and professional fees vary with the complexity of the operating agreement.
Is an LLC or a corporation cheaper to maintain in Massachusetts?
The annual report fee is lower for corporations, but a C corporation pays at least the $456 minimum corporate excise and taxes on its income, while an LLC taxed as a partnership does not pay the corporate excise. The overall answer depends on income, the owners’ tax situations and whether an S election is planned.
Can I form a series LLC in Massachusetts?
No. The Massachusetts LLC Act does not provide for series. Owners who want to segregate assets usually form separate LLCs, sometimes owned by a single holding company.
Do I need a Massachusetts resident agent?
Yes. Every Massachusetts LLC and corporation, and every registered foreign entity, must maintain a resident or registered agent in the Commonwealth to receive service of process and official notices.
Should I form my company in Delaware instead?
For a business operating only in Massachusetts, a Delaware entity usually adds fees and filings in two states. Companies expecting institutional venture investment often choose Delaware because investors expect it. The right answer depends on the growth and financing plan.
Can a professional practice form an LLC in Massachusetts?
Yes, licensed professionals may use a professional corporation under c. 156A or an LLC that renders professional services under c. 156C, subject to licensing board requirements. Neither shields a professional from liability for his or her own professional conduct.
