How to Form a PLLC in Massachusetts: Name, Filing, and Agent

To form a PLLC in Massachusetts, every member or manager who will deliver professional services must be licensed by the relevant state board, and you file a Certificate of Organization with the Secretary of the Commonwealth under General Laws Chapter 156C, Section 12, with a board-issued licensure certificate attached for each of those professionals. The filing fee is $500.¹ The rest is sequencing: confirm you qualify, clear a name, collect the board certificates, file, appoint a resident agent, get an EIN, and put an operating agreement in place.

Confirm You Qualify

A PLLC is only for people who need a state license to practice their occupation. Physicians, attorneys, architects, accountants, and engineers are the common examples, and other licensed professions qualify as well. Every member or manager who will render professional services in Massachusetts must be “duly licensed” by the board that regulates the field.²

If your work does not require a state license, you form a regular LLC instead. The PLLC also limits the entity to rendering the specific professional service named in the certificate, so it is not a general-purpose business vehicle.

Choose and Clear a Name

The name must include a limited liability company designator: “Limited Liability Company,” “LLC,” or another abbreviation recognized under Chapter 156C, Section 3.³ It cannot be the same as, or deceptively similar to, any corporation, limited partnership, or LLC already on file with the state, unless you obtain written consent from that entity. Search the Secretary of the Commonwealth’s business entity database before you commit to a name or order signage.

Get Certificates From Your Licensing Board

This is the step that gates the whole filing. Contact the board that regulates your profession and request a certificate confirming that each member or manager who will practice through the PLLC holds an active license. The Certificate of Organization requires you to attach a certificate from the applicable regulating board for every person who will render professional services in the Commonwealth, and the Secretary of the Commonwealth will not process the filing without them.²

Processing times vary by board, so start this early. If you are forming with partners, one missing certificate holds up everyone.

File the Certificate of Organization

The formation document is the Certificate of Organization, filed with the Secretary of the Commonwealth under Chapter 156C, Section 12. The fee is $500.¹

The certificate must include:

The PLLC’s full legal name with a qualifying designator.
The specific professional service the PLLC will provide.
Names and addresses of each member or manager who will deliver professional services, with their licensing board certificates attached.
The name and Massachusetts street address of a resident agent, plus that agent’s written consent to serve.
The address of the PLLC’s office in the Commonwealth.
A brief description of the general character of the business.

The PLLC comes into existence when the Secretary of the Commonwealth accepts the filing, or on a later effective date you specify in the certificate itself.¹

Appoint a Resident Agent

Every Massachusetts PLLC must designate a resident agent to accept legal documents, state notices, and tax correspondence for the company. The agent must be either an individual with a residence and business address in Massachusetts, or a business entity authorized to operate in the state. A P.O. box does not qualify.

The agent has to be physically available at the listed street address during normal business hours. A member can serve as the agent, but if you travel or work from multiple locations, missing a served lawsuit at that address is a real risk, and many PLLCs use a commercial registered agent service for that reason.

Draft an Operating Agreement

Massachusetts does not require an operating agreement to form a PLLC, but skipping one is a mistake. Without a written agreement, management defaults to all members having equal say, which may not match a practice where partners have different roles, seniority, or capital contributions. Courts look to operating agreements to resolve member disputes, and having nothing in writing leaves you with the default statutory provisions, which rarely reflect what the members actually intended.

At minimum, the agreement should address:

How profits and losses are allocated among members.
Voting rights and management authority.
How new members are admitted.
What happens if a member’s license is suspended, revoked, or allowed to lapse.
Buyout procedures when a member leaves, retires, or dies.

Because a PLLC is restricted to licensed professionals, the license-loss provision is not optional housekeeping. It is the mechanism that lets the practice continue if one member can no longer legally serve clients.

Get a Federal EIN

Once the state has accepted your Certificate of Organization, apply for a federal Employer Identification Number from the IRS. You need an EIN to open a business bank account, hire employees, and file federal tax returns. The online application on IRS.gov is free and issues the EIN immediately.⁴

Wait for state approval before applying. Submitting an EIN request before the PLLC is on file with Massachusetts can create name and entity mismatches that take real time to unwind. The application asks for the PLLC’s exact legal name as it appears on the certificate, the responsible party’s Social Security number, and the entity’s business address. Finish the application in one sitting, because the IRS system times out after 15 minutes of inactivity and does not save progress.

After Formation: Staying in Good Standing

Formation is the start of a recurring compliance cycle rather than a one-time task.

Annual Report

Every Massachusetts PLLC must file an annual report with the Secretary of the Commonwealth by the anniversary of its formation date, with a $500 fee each year.⁵⁶ The report confirms the PLLC’s current name, office address, resident agent, managers, and the members or managers rendering professional services. Missing two consecutive annual reports is grounds for administrative dissolution.

Active Licensure for Every Practicing Member

Each member or manager who delivers professional services must keep their license current for as long as they practice through the PLLC. Renewal cycles differ by profession, so track them separately for every member. A lapse affects both the individual and the PLLC’s standing.

Taxes

By default, Massachusetts follows the federal check-the-box rules: a single-member PLLC is a disregarded entity and a multi-member PLLC is taxed as a partnership, with income flowing through to the members.⁷ Because there is no employer withholding on that income, members generally make quarterly estimated tax payments to the Massachusetts Department of Revenue and the IRS. A PLLC can also elect corporate tax treatment with the IRS, in which case Massachusetts treats it as a corporation and requires it to register for the corporate excise. That election adds complexity and is worth running past a tax advisor before making.

Records

Keep organized internal records: member names and addresses, meeting minutes or written consents, and financial statements. These records back up the PLLC’s separate identity if the state or a court ever questions it, and they are the first thing a judge will ask for in a member dispute.
