Massachusetts LLC Operating Agreement: Oral vs. Written Rules (2026)

A Massachusetts LLC operating agreement defines how your limited liability company operates, from ownership splits to exit rules. Massachusetts is one of the few states that still recognizes oral operating agreements under M.G.L. c. 156C, but only a written version triggers the statute’s strongest protections.

Under M.G.L. c. 156C, § 2(9), the Massachusetts Limited Liability Company Act defines an operating agreement as “any written or oral agreement of the members.” That statutory language matters. Massachusetts doesn’t limit the agreement to a formal printed document the way most states do.

Here’s the thing: oral recognition doesn’t mean oral is smart. Section 11 of Chapter 156C protects members and managers who rely in good faith on a written operating agreement. That protection vanishes if the agreement exists only as a verbal understanding. Section 9 reinforces the point by requiring every LLC to keep copies of any written operating agreement at its principal office.

The operating agreement works alongside the Certificate of Organization, the formation document filed with the Secretary of the Commonwealth’s Corporations Division. The certificate handles public-facing details (LLC name, resident agent, management structure). The operating agreement handles internal governance: who owns what, how decisions get made, and what happens when a member leaves.

Before filing that certificate, confirm your LLC name isn’t already taken using the Massachusetts business entity search tool on Mass.gov.

Does Massachusetts Law Require an Operating Agreement?

No. Massachusetts doesn’t require LLCs to adopt an operating agreement, and the Corporations Division won’t ask for one during formation. The only document you’ll file is the Certificate of Organization, which costs $500.

That said, skipping an operating agreement doesn’t create a governance vacuum. Chapter 156C fills every gap with default rules that may not match how you run your business. According to Aaron Kra, JD, Boost Suite’s legal editor, the defaults catch first-time LLC owners off guard more often than any other compliance issue in the Commonwealth.

Massachusetts Default Rules When No Operating Agreement Exists

Every LLC that operates without a written agreement is governed by the following Chapter 156C defaults:

Worth flagging: the profit allocation default under § 29 doesn’t split profits equally. It allocates based on the agreed value of each member’s contributions. If one member invested $100,000 and another invested $10,000, each distribution follows those amounts. That catches owners who assume equal membership means equal payouts.

What to Include in a Massachusetts LLC Operating Agreement

A written operating agreement should cover topics where Chapter 156C defaults won’t match your intent. Boost Suite recommends these four areas first.

Ownership Percentages and Capital Contributions

Spell out each member’s ownership percentage and initial capital contribution in dollar terms. If the agreement doesn’t address future contributions, no member can be forced to invest more. Section 29’s default ties profit allocation directly to contribution value, so a vague ownership clause creates ambiguity at tax time.

For LLCs with two or more members, include a valuation method for non-cash contributions (equipment, intellectual property, real estate). The IRS expects consistency between your operating agreement and your Form 8832 or Form 2553 election if you’ve chosen a specific tax classification.

Voting Rights and Day-to-Day Decision-Making

Section 21(d) defaults to a vote by members holding more than 50% of unreturned contributions. For a two-member LLC with equal investment, that means deadlock on every contested decision. A well-drafted voting rights clause sets different thresholds: simple majority for ordinary business, supermajority for extraordinary actions like admitting a new member or selling major assets.

Day-to-day operations don’t need a formal vote for every invoice. Clarify which decisions require member approval and which fall within a designated manager’s authority.

Transfer Restrictions and Member Exit Rules

Under § 41, assigning an LLC interest doesn’t automatically make the buyer a full member. The assignee receives economic rights (distributions, profit share) but not governance rights. Full admission requires unanimous approval from remaining members or written procedures spelled out in the operating agreement.

The exit side is equally important. Section 36 guarantees any member the right to resign on six months’ prior written notice. The operating agreement can’t override this. Section 32 adds that a resigning member without a written payout clause is entitled to the fair value of their LLC interest within a reasonable time. Without a buyout formula, “fair value” becomes a dispute waiting to happen.

Dissolution Triggers and Winding Up

Section 43 lists the default dissolution triggers: a time or event specified in the agreement, unanimous written consent of all members, or judicial decree under § 44. Administrative dissolution under § 70 rounds out the list.

Administrative dissolution kicks in when the LLC fails to file annual reports for two consecutive years. The Corporations Division sends a 90-day cure notice first. Reinstatement costs $100 plus all overdue annual report fees, and that adds up fast at $500 per missed year. For processing timelines, see Boost Suite’s guide on Massachusetts LLC processing times.

Member-Managed vs. Manager-Managed: How Massachusetts Treats Each Structure

Under § 24, every Massachusetts LLC is member-managed by default unless the operating agreement assigns control to one or more managers. Section 25 adds a detail most states share but few owners know: a manager doesn’t need to be a member.

The filing consequences are where Massachusetts gets stricter. If the LLC has managers at formation, their names and addresses must appear in the Certificate of Organization. No managers? The certificate must identify at least one authorized person who can execute filings.

Changing the management structure later requires a Certificate of Amendment filed with the Corporations Division. That costs $100.

The liability shield under § 22 protects both members and managers from personal liability for LLC debts solely because of their status. The structure choice changes who has signing authority and who controls daily operations, not the strength of that shield.

Single-Member vs. Multi-Member Massachusetts Operating Agreements

Massachusetts expressly allows LLCs to have one or more members. The statute doesn’t impose different rules for single-member LLCs, but the practical stakes differ.

For a sole owner, the operating agreement proves the LLC is a separate entity (critical in veil-piercing challenges), satisfies bank requirements, and documents succession plans. Single-member companies without this document risk having a court treat personal and business finances as one. The separateness evidence matters when financial records are reviewed during litigation.

A multi-member LLC without an operating agreement is a dispute waiting to happen. The leading Massachusetts case, Allison v. Eriksson, 479 Mass. 626 (2018), reinforced that courts treat the agreement as a binding contract. The Supreme Judicial Court held that merger remedies aren’t limited to the statutory payout when fiduciary duties are breached. Minority protections in the operating agreement changed the outcome entirely.

Based on Boost Suite’s analysis of Chapter 156C, every multi-member LLC should address voting, distributions, transfers, and fiduciary duties in writing before accepting capital contributions.

Three Massachusetts Clauses Most LLC Owners Miss

Competitor guides cover the basics: ownership, voting, profits. These three provisions are Massachusetts-specific and absent from nearly every template.

The Six-Month Resignation Override (§ 36)

Even if the operating agreement prohibits resignation, § 36 gives every member the right to resign on six months’ prior written notice. The operating agreement can set conditions around the payout, but it can’t eliminate the right to leave. For multi-member LLCs, buyout planning isn’t optional.

Expanding or Restricting Fiduciary Duties (§ 63(b))

Massachusetts allows the operating agreement to expand or restrict fiduciary duties owed between members and managers. The Allison v. Eriksson decision confirmed this. It’s a powerful drafting lever for LLCs where one member is passive and another runs daily operations. Without a clause addressing fiduciary standards, the defaults apply.

The Real-Property Signing Authority Trap (§ 66)

If the Certificate of Organization names a manager or authorized person as the real-estate signer, a recordable instrument signed by that person can bind the LLC. Good-faith third parties are protected under § 66, even if the operating agreement restricts that person’s authority internally. A restrictive OA clause won’t help if the certificate says something different.

Massachusetts LLC Costs That Affect Your Operating Agreement Budget

Massachusetts ranks among the most expensive states for LLC maintenance. Here’s the fee breakdown as of 2026:

That’s $1,000 in year one before you count legal help, a resident agent, or an EIN application. For a complete breakdown, see Boost Suite’s Massachusetts LLC fee guide.

Massachusetts doesn’t impose a standalone annual franchise tax on LLCs. Tax treatment depends on the LLC’s federal classification: disregarded entity, partnership, C-corp, or S-corp. LLCs that elect corporate treatment face the state’s Corporate Excise. Eligible pass-through entities may opt into the elective PTE excise through MassTaxConnect.

The catch: a disregarded entity doesn’t qualify for the Massachusetts PTE election. If your single-member LLC wants that option, you’d need to add a member or elect corporate treatment first.

How to Sign and Store Your Massachusetts LLC Operating Agreement

All members should sign the operating agreement on the same day if possible. Massachusetts doesn’t require notarization or witnesses. Signatures alone establish the document’s validity.

Section 9 of Chapter 156C requires every LLC to maintain copies of any written operating agreement at its principal office. The agreement doesn’t get filed with the Secretary of the Commonwealth. It stays internal.

One Massachusetts-specific term to know: the statute uses resident agent, not “registered agent.” Every LLC must appoint a resident agent with a physical address in the Commonwealth. Boost Suite’s review of Massachusetts resident agent providers compares pricing across a dozen services.

After the operating agreement is signed, the next step is starting your Massachusetts LLC by filing the Certificate of Organization and applying for an EIN through IRS Form SS-4. If you plan to operate under a name different from your LLC’s legal name, a separate DBA filing is also required.
