Start a Massachusetts LLC: Step-by-Step Guide

Under Chapter 156C, Section 3, your LLC name can't be the same as, or deceptively similar to, the name of any corporation, limited partnership, or LLC already on the Commonwealth's records, unless that business gives written consent. Two names that differ only by punctuation, spacing, or a filler word like "the" may be treated as the same, and the Corporations Division can reject your Certificate if your name is too close to one already in use.

Start with the Commonwealth's business entity search. Search your exact proposed name and a few near variations. Read the results for anything that sounds or spells similarly. That is what a state examiner will do.

Massachusetts naming rules

• The name must include "limited liability company," "limited company," "L.L.C.," "L.C.," "LLC," or "LC"
• It can't be the same as, or deceptively similar to, a corporation, limited partnership, or LLC on record
• The exception is written consent from the business whose name is similar

Reserving a name (optional)

If you have settled on a name but are not ready to file, Massachusetts lets you reserve it through the Corporations Division for $30. A reservation lasts 60 days, and the Secretary can extend it once for another 60 days on written request. Reservations can't be filed by fax. Reservation holds the name; it does not create the LLC. Most people who are ready to file simply file, because filing itself locks the name.

Operating under a different name (DBA)

If you intend to trade under a name other than your LLC's legal name, Massachusetts handles that at the local level. You file a business certificate (a "doing business as" filing) with the clerk of each city or town where you do business, not with the Secretary of the Commonwealth. Rules, fees, and terms vary by municipality, and many require the form to be notarized. It is a separate process from forming the LLC.

Before you file, you need a resident agent (Massachusetts's term for a registered agent) chosen and willing to serve, because the agent is named directly on the Certificate of Organization and signs a consent on it: "I, resident agent of the above limited liability company, consent to my appointment as resident agent." The resident agent is the person or company that receives lawsuits, subpoenas, and official state mail on behalf of your LLC, and Massachusetts requires you to keep one at all times.

Under 950 CMR 112.13, the resident agent's office address must be a street address; a post office address is not sufficient.

Who can serve

Chapter 156C, Section 5 lists an individual resident of Massachusetts, a domestic corporation, or a foreign corporation authorized to do business in the Commonwealth. The Division's regulation also accepts other domestic business entities authorized by law and qualified foreign ones.

• You: if you live in Massachusetts. Your address will appear in the public record.
• Another resident: a co-owner, an employee, an attorney, or another trusted person willing to accept documents.
• A commercial resident agent service: a corporation or other qualified entity that acts as an agent. It keeps its own professional address on the public record instead of yours and forwards documents promptly when they arrive.

Why it matters which one you pick

Whatever address you list becomes searchable on the Commonwealth's public database. If you use your home, anyone looking up the LLC finds where you live. That is the main reason many owners choose a commercial service. It keeps the home address private. It also means legal process has a dependable place to land even when you are on the road.

The Certificate of Organization is the filing that legally creates your LLC in Massachusetts; the state does not use "Articles of Organization" for LLCs. You file it through the Corporations Division's online filing system or by mail or hand to the Division at One Ashburton Place, Room 1717, Boston.

The filing fee is $500. The fee schedule adds a $20 expedite fee to every fax and electronic filing at that amount, so filing online costs $520 and a mailed certificate costs $500. The Division doesn't publish a standard processing time, so if a date matters, file early.

What the Certificate asks for

• LLC name: your full legal name with an approved designator
• Office address: the street address of the office in Massachusetts where the LLC's records will be kept
• General character of the business: a short description of what the company does
• Latest date of dissolution, if any
• Resident agent: name and Massachusetts street address, plus the agent's signed consent
• Managers, if any, and the people authorized to sign documents filed with the Division
• Real estate signatories: the people authorized to sign recordable instruments affecting real property
• Signature: at least one authorized signatory signs

What you do not have to disclose

You do not have to list every member or reveal ownership percentages, and you do not disclose revenue or any financial figures. The internal details (who owns what, how profits are split) live in your operating agreement, which stays private and never reaches the state.

The operating agreement is your LLC's internal rulebook. Massachusetts does not require you to file it, and it never enters any public database, but you should have one signed before you take on partners, open accounts, or start doing real business.

What a solid operating agreement covers

• Ownership: each member's name and percentage interest
• Capital contributions: what each member put in at the start and any future contribution obligations
• Profit and loss allocation: how gains and losses are divided; it usually tracks ownership but does not have to
• Distributions: when and how cash actually gets paid out, and in what order
• Management: whether the LLC is member-managed or manager-managed, who has day-to-day authority, and which decisions need a full member vote
• Voting: whether votes are weighted by ownership or counted per member
• Transfers: what happens when a member wants to sell or leave, including rights of first refusal and approval requirements
• Dissolution: the circumstances under which the LLC winds down and how assets are distributed

For a single-member LLC, the agreement documents that the company is a real, separate entity; courts weigh that when someone challenges the liability shield, and banks often ask for it. For a multi-member LLC, it is essential: without it, Chapter 156C's default rules decide these questions for you, and the defaults rarely match what the members actually intended.

An Employer Identification Number is a no-charge, nine-digit federal tax ID handed out by the IRS. It functions as the business version of a Social Security number. You use it on tax filings, to open bank accounts, and to hire employees.

When you need one

• Your LLC has more than one member (a multi-member LLC files a partnership return and must have an EIN)
• You plan to hire employees
• You want a business bank account (most banks require the EIN)
• You have elected S-corporation or C-corporation tax treatment

A single-member LLC with no employees can technically use the owner's Social Security number for federal purposes, but most advisors get an EIN anyway. It keeps your SSN off business paperwork and streamlines opening accounts.

How to apply

Apply free through the IRS EIN Assistant at IRS.gov. The online application takes about ten minutes and issues the number immediately. You can print the confirmation and use it the same day. The online tool requires a U.S. Social Security number or ITIN; applicants without one apply by fax or mail on Form SS-4. The Certificate only asks for an EIN "if available," so forming first and applying second works fine. When Mainstay forms your LLC, we apply for the EIN for you.

A separate bank account is not optional if you want the liability shield to hold. Paying personal expenses from the business account, or funneling business income through your personal checking, gives a court grounds to disregard the LLC and hold you personally responsible.

What banks typically want

• Your filed Certificate of Organization from the Corporations Division
• Your IRS EIN confirmation
• Your operating agreement, which many banks ask for, so have it ready regardless
• Government-issued ID for every authorized signer

Community banks and credit unions in Massachusetts are often more flexible with brand-new LLCs than the big national chains, and several online business banks can open an account without a branch visit. Weigh the monthly fees, transaction caps, and minimum-balance rules side by side before making a choice.

Most of the work is front-loaded into formation. After that, the recurring burden is one significant annual filing plus attention to any change in your agent or address.

Annual report

Massachusetts requires an annual report for every LLC, due each year on or before the anniversary of the date your original Certificate of Organization was filed, not a fixed statewide date. The fee is $500, or $520 when filed through the Corporations Division's online system. The report carries the same information as your Certificate, with any changes. If an LLC misses its annual reports for two consecutive years, the Division can start a dissolution proceeding, and the LLC is administratively dissolved if it doesn't fix the problem within 90 days of the notice. A dissolved LLC can apply for reinstatement, but filing on time is far simpler.

Resident agent upkeep

If your agent moves, resigns, or you switch agents, file a Statement of Change of Resident Agent/Resident Office promptly. It's free when filed electronically and $25 on paper. A stale agent address leaves the LLC out of compliance even when everything else is current.

Taxes

Federal treatment depends on your classification: a single-member LLC files Schedule C, a multi-member LLC files Form 1065, and an S-corp election files Form 1120-S. Massachusetts taxes personal income, so pass-through income reaches members' state returns. If you have employees, register for withholding, and if you sell taxable goods or services, register for sales tax, both through the Massachusetts Department of Revenue.

Licenses and local permits

Massachusetts has no single statewide business license. Many professions are licensed by state boards, and your city or town may require local permits or a local business certificate. These run on their own schedules and are separate from your Corporations Division filings.
