To start an LLC in Massachusetts, you file a Certificate of Organization with the Secretary of the Commonwealth for a $500 fee, after picking a compliant name and lining up a resident agent. Online filings go through in a few business days. Then you get a federal EIN, register with the Massachusetts Department of Revenue, and plan on paying another $500 every year to keep the LLC in good standing.
Pick a Name That Meets the Rules
Your LLC’s name must include “Limited Liability Company,” “Limited Company,” or an abbreviation like “LLC,” “L.L.C.,” “LC,” or “L.C.” It also can’t be identical or deceptively similar to any existing corporation, limited partnership, or LLC already on file, unless that entity gives you written consent.1General Court of Massachusetts. Massachusetts General Laws Part I, Title XXII, Chapter 156C, Section 3
Search the business entity database on the Secretary of the Commonwealth’s website to see whether your name is available.2Mass.gov. Starting a Limited Liability Company in Massachusetts If you’re not ready to file, you can reserve the name for 60 days for $30, with one 60-day extension for another $30.3Secretary of the Commonwealth of Massachusetts.

Appoint a Resident Agent
Every Massachusetts LLC needs a resident agent to accept legal documents on its behalf. The agent must be either an individual with a residential and business address in Massachusetts, or a corporation authorized to do business in the state.4Legal Information Institute. Massachusetts Code 950 CMR 111.08 – Registered Agent The agent’s written consent has to be included with or attached to the Certificate of Organization when you file.5General Court of Massachusetts. Massachusetts General Laws Chapter 156C, Section 12
You can be your own agent if you have a Massachusetts address and will reliably be there during business hours. Commercial agent services run about $35 to $350 a year and keep your home address off the public record.
File the Certificate of Organization
The Certificate of Organization is what actually creates your LLC. The filing fee is $500, and the LLC exists once the Secretary’s office accepts and files the document.5General Court of Massachusetts. Massachusetts General Laws Chapter 156C, Section 12
The certificate requires:5General Court of Massachusetts. Massachusetts General Laws Chapter 156C, Section 12
- The LLC’s name, meeting the naming rules above.
- A physical Massachusetts office address.
- The resident agent’s name and address, with written consent attached.
- If the LLC has managers, their names and addresses; otherwise, at least one person authorized to sign documents on the LLC’s behalf.
- A brief description of the general character of the business.
- A dissolution date, only if you want the LLC to end on a set date.

If You’re a Licensed Professional
Doctors, lawyers, accountants, and other licensed professionals may need to form a Professional LLC (PLLC) rather than a standard LLC. The fee is still $500, but the certificate also requires the specific professional service, the name and address of each member or manager who will practice in Massachusetts, and a certificate from the relevant licensing board confirming everyone is properly licensed.6Secretary of the Commonwealth of Massachusetts. Professional Limited Liability Company Certificate of Organization A PLLC shields members from the business’s general debts but does not shield them from their own malpractice.
Get an EIN
Once the state has formed your LLC, apply for an Employer Identification Number from the IRS. The IRS asks that your entity exist with the state before you apply, so don’t do this out of order.7Internal Revenue Service. Get an Employer Identification Number You need one if you have employees, pay certain excise taxes, or withhold on payments to nonresident aliens, and you’ll typically need one for banking and state tax registration anyway.8Internal Revenue Service. Employer Identification Number The online application is free and takes about 15 minutes, with the EIN issued at the end.
Register with the Massachusetts Department of Revenue
With your EIN in hand, register your LLC through MassTaxConnect.9Mass.gov. Register Your Business with MassTaxConnect You’ll enter your EIN, business start date, and contact information including Social Security numbers for owners and officers, and then sign up for the specific taxes that apply, such as sales tax, employee withholding, or corporate excise. Owners who skip this step tend to find out about it through penalties.
Decide How Your LLC Will Be Taxed
The IRS gives you a default classification based on membership. A single-member LLC is a disregarded entity by default, with business income reported on the owner’s personal return. A multi-member LLC is treated as a partnership by default, filing an informational return while income flows through to each member.10Internal Revenue Service. Single Member Limited Liability Companies
If the default doesn’t suit you, file Form 8832 to elect C corporation treatment,11Internal Revenue Service. About Form 8832, Entity Classification Election or Form 2553 for S corporation treatment. S-corp status can reduce self-employment taxes for owners who pay themselves a reasonable salary, at the cost of stricter administrative requirements. Switching classifications later is messy, so it’s worth running the numbers with a tax professional before you elect.
Massachusetts follows your federal choice. A disregarded entity federally is a disregarded entity for state purposes; a corporate election triggers Massachusetts corporate excise tax and the matching registration on MassTaxConnect.12Mass.gov.

Write an Operating Agreement
Massachusetts doesn’t explicitly require an operating agreement, but the LLC statute leans on it constantly. Section 24 of Chapter 156C repeatedly uses “unless otherwise provided in the operating agreement” to govern management, authority to sign, and other core questions.13General Court of Massachusetts. Massachusetts General Laws Part I, Title XXII, Chapter 156C, Section 24 Without one, you get the statute’s defaults, which may not match what you and any co-owners actually intended.
A workable agreement covers ownership percentages, how profits and losses are split, each member’s role, voting procedures, and what happens if a member leaves or the LLC dissolves. Even single-member LLCs benefit from one, because a written agreement helps show the LLC is a real entity rather than an extension of your personal finances if your liability protection is ever challenged.
File an Annual Report Every Year
Every Massachusetts LLC has to file an annual report with the Secretary of the Commonwealth, updating basic information like office address, resident agent, and managers. It’s due on the anniversary of your LLC’s formation, and the fee is $500.5General Court of Massachusetts. Massachusetts General Laws Chapter 156C, Section 12
Miss it, and the state can administratively dissolve your LLC, meaning its legal existence is revoked. Reinstatement costs an additional $100 on top of any overdue report fees.14Secretary of the Commonwealth of Massachusetts. Filing Fees A calendar reminder a month before your anniversary is the easiest fix.
Your city or town may require a local business certificate, and some industries need professional permits. Check with your municipal clerk and any applicable state licensing boards for your specific business.15Mass.gov. Starting a Business in Massachusetts
Keep the Liability Shield Intact
Forming the LLC is the easy part. If a court decides you treated the LLC as an extension of your own wallet, it can pierce the veil and hold you personally liable for business debts.
The most common mistake is mixing personal and business money. Open a dedicated business bank account and business credit card, and use them only for business. Pay yourself through documented distributions or a salary rather than dipping in for personal purchases. Sign contracts, invoices, and leases in the LLC’s name, not your own. Keep records of major decisions, file your annual reports on time, carry adequate insurance, and leave enough capital in the business to meet its foreseeable obligations. None of this is hard in any given month; it’s letting those habits lapse over years that costs owners the protection they formed the LLC to get.
