Connecticut LLC Operating Agreement Guide: What the Law Allows and What to Include

A Hartford bank asks for your LLC's operating agreement before opening a business checking account. You search your files and find nothing, because Connecticut never required you to file one anywhere. Gaps like it catch new LLC owners off guard every year.

Connecticut law does not force an LLC to write an operating agreement. The Secretary of the State never asks to see one. A bank, investor, buyer, lender, or accountant will ask for it, though. Without a written document, the LLC runs on the state's default rules instead of the members' decisions. Default rules work fine for some businesses and badly for others. The sections below cover what Connecticut's LLC statute requires. They also cover what a solid operating agreement includes, and which provisions no agreement can override.

Key Takeaways

·        Connecticut does not require LLCs to file an operating agreement with the state.

·        CGS Section 34-243a defines the agreement broadly, and it can cover a single member.

·        Without a written agreement, Connecticut's statutory default rules govern the LLC instead.

·        Certain provisions, like registered-agent and filing duties, cannot be waived by any agreement.

·        Banks, investors, and lenders commonly request a copy before doing business with the LLC.

Direct Answer: Is It Required, and Why Write One Anyway

Connecticut does not list an operating agreement among the filing requirements for forming an LLC. Nothing in Chapter 613a of the Connecticut General Statutes forces a member to draft one. No provision requires a member to sign one or send one to the state. A missing agreement still carries a real cost, though.

Without a written agreement, the LLC operates under Connecticut's statutory default rules. Default rules cover profit splits, voting, management authority, and what happens when a member leaves. Default rules assume every member holds equal standing, which rarely matches how a real business runs. A two-member LLC illustrates the point. One partner put in $80,000 and the other put in $5,000, and neither wants equal profit splits by default. A written agreement avoids the mismatch.

A written agreement also solves a practical problem. Banks ask for it before opening a business account. Investors ask for it before writing a check. Buyers ask for it before purchasing a stake. Accountants ask for it before filing a return based on the members' actual arrangement. An LLC without a written agreement can answer none of the requests with a document, only with a verbal explanation.

What Connecticut Law Means by "Operating Agreement"

CGS Section 34-243a defines the operating agreement in broad terms. The section sits inside Connecticut's Uniform Limited Liability Company Act, Chapter 613a. The definition covers the agreement of all members of an LLC, including amendments. It specifically includes the agreement of a sole member. A one-person LLC in Connecticut still has an operating agreement under the statute. It exists even if the sole owner never wrote anything down.

The statute treats the operating agreement as the governing document for internal matters. Under CGS Section 34-243d, the agreement governs member relations, manager duties, company activities, and amendment procedures. The chapter sets limits on how far the agreement can go. Put simply, the members set most of the internal rules for the business themselves. The rules just can't conflict with a handful of protected statutory provisions.

Written vs. Oral vs. Implied Agreements

Connecticut's definition of an operating agreement does not require a signature or even a written page. CGS Section 34-243a allows the agreement to be written, oral, implied from conduct, or a combination of the three. Consider a group of members who never wrote anything down. They split profits 60/40 for three years, which counts as an oral or implied agreement to the split.

A verbal or implied agreement holds up in theory. It usually fails once a dispute lands in front of a judge or an accountant. Memory alone rarely proves what three people agreed to two years ago. A signed written agreement removes the guesswork. It gives the members, and anyone reviewing the LLC's finances, a single reference point instead of competing memories.

What Statutory Default Rules Do

Connecticut's LLC statute fills gaps automatically. Members sometimes leave an issue out of the written agreement, by choice or oversight. The statutory default rules then step in and control the outcome. The defaults touch voting thresholds, distribution timing, a member's right to information, and dissolution triggers, among other topics.

Default rules are not bad rules. They work as a reasonable baseline for a simple, single-member consulting company with no partners and no outside investors. The same defaults create friction for a multi-member LLC with unequal contributions or a passive investor. A family succession plan adds another layer. The more complex the ownership structure, the more the written agreement matters.

Single-Member LLC Provisions

A single-member LLC in Connecticut still counts as an LLC with an operating agreement under CGS Section 34-243a. The statute treats it so, even without a partner to negotiate with. A sole owner might ask why the paperwork matters at all.

A written agreement still separates the owner's personal assets from the business. A bank, a court, or an accountant sees the separation clearly. A Connecticut consulting business run by one person benefits from a written agreement. The agreement can name the business's manager and state how profits get withdrawn. It can also confirm the LLC continues if the sole member becomes incapacitated or dies. Without the language, a family member or a court has to guess what the sole owner intended for the business.

Multi-Member Ownership and Voting

A two-member Connecticut LLC with ownership split 50/50 needs a plan for what happens when the two members disagree. Connecticut's default rules require majority consent for most ordinary decisions, but a 50/50 LLC has no majority. Without a tie-breaking provision, a genuine disagreement can freeze the business.

Ownership percentage and voting power are not always the same thing, and the agreement should say so directly. A passive investor might contribute capital without running daily operations. The investor could still hold a smaller vote than an active manager who built the business day to day. Confusion between profit share and voting rights causes real disputes among Connecticut LLC members. The agreement should spell out each one separately.

Member-Managed vs. Manager-Managed Operation

Connecticut LLCs choose between two management structures, and the operating agreement should state the choice plainly. A member-managed LLC gives every member authority to act on the company's behalf. A manager-managed LLC narrows the authority to one or more named managers, while the other members stay passive.

A family-owned Connecticut LLC planning succession commonly mixes the two structures. The founding generation might serve as managers while adult children hold membership interests without daily authority. The arrangement can last until a transition date named in the agreement. The structure should reflect how decisions get made in practice, more than how the ownership is split.

Capital Contributions and Distributions

The agreement should record what each member contributed to the LLC, whether cash, equipment, property, or services. It should also record the value assigned to each contribution. Consider a Connecticut LLC where one partner contributed $80,000 and the second contributed $5,000 plus sweat equity. The agreement needs to record each contribution precisely, along with how it affects profit share and voting.

Distribution rules deserve equal attention. The agreement should state when the LLC distributes profits. It should also cover how the LLC handles a year with no profit to distribute. Distributions can match ownership percentage or follow a different formula the members agreed on.

Transfers, Departures, Death, Disability, and Buyouts

Members leave LLCs for ordinary reasons: retirement, disagreement, death, or a move out of state. A Connecticut operating agreement should set the terms before any of it happens, not after.

A family-owned LLC planning succession benefits from a buyout formula. The formula values a departing member's interest without a public appraisal fight. The agreement should name who can buy a departing member's interest, in what order, and at what price or formula. It should also state what happens if a member dies or becomes disabled. Connecticut's default rules don't automatically hand daily authority to an heir with no interest in running the business.

Tax Elections and Accounting Authority

An LLC's operating agreement can name who holds authority to make tax elections and hire an accountant. It can also name who chooses the LLC's tax classification with the IRS. For a full walkthrough of Connecticut's tax obligations, see Connecticut Business Taxes Explained.

Members sometimes want to write tax promises into the agreement, guaranteeing a certain deduction or a specific treatment. A signed agreement cannot guarantee a tax outcome, since tax law changes and every LLC's situation differs. A Connecticut CPA or tax attorney should review any tax-related clause before it goes into a final agreement.

Fiduciary Duties and Nonwaivable Provisions

Connecticut law lets members customize most of the operating agreement. CGS Section 34-243d and related sections in Chapter 613a set limits on what the agreement can waive. A member-drafted agreement cannot eliminate the duty of good faith and fair dealing. It cannot authorize intentional misconduct or a knowing violation of law. It also cannot waive a member's right to bring legal claims against a manager who acts in bad faith.

The agreement also cannot override Connecticut's registered agent requirement or the requirement to file with the Secretary of the State. The filing and agent duties exist independent of what the members write. A Connecticut LLC still needs a registered agent, regardless of what the operating agreement says. See Connecticut Registered Agent Guide for the specifics.

Amendments and Recordkeeping

An operating agreement is not a static document. CGS Section 34-243d lets members amend the agreement over time. The agreement itself should state the vote or consent needed to approve a change. A Connecticut LLC might add a new member, bring on an investor, or shift from member-managed to manager-managed. Any of the changes calls for an updated agreement, right away and not months later.

Keep the signed agreement, and every amendment, with the LLC's other records. A bank or a buyer conducting due diligence will want the full history, along with the current version.

DIY Template vs. Attorney Drafting

A basic template works for some Connecticut LLCs. A single-member consulting business with no partners or outside investors is a good example. A downloaded template still gives the LLC a written record instead of nothing.

A template works fine at the start. It stops being enough once the LLC adds a second member, a passive investor, or a succession plan. Unequal contributions between partners raise the stakes even further. An attorney costs money upfront. The cost is still small compared to a dispute over voting power or a buyout formula written poorly. A Connecticut attorney who works with LLCs can help too. The attorney can confirm the agreement doesn't conflict with the nonwaivable provisions in Chapter 613a.

FAQ

Is an operating agreement required in Connecticut?

No. Connecticut's LLC statute does not require a member to draft or file an operating agreement. A written agreement remains strongly recommended. It replaces the state's default rules with terms the members chose themselves. It also gives banks, investors, and accountants a document to review.

Does a single-member LLC need one?

A single-member LLC still counts as having an operating agreement under CGS Section 34-243a, even if nothing is written down. A written version still helps a sole owner. It separates business and personal finances clearly. It also states what happens to the business if the owner becomes incapacitated or dies.

Do I file it with the state?

No. The operating agreement stays with the LLC's internal records and never goes to the Connecticut Secretary of the State. Filing requirements cover different documents, like the certificate of organization. See How to Form an LLC in Connecticut for the separate process.

Can it be oral?

Connecticut law allows an oral or implied operating agreement, and CGS Section 34-243a recognizes it as valid. An oral agreement holds up poorly once a dispute reaches a bank, a court, or an accountant. No signed record exists to prove the actual terms.

What happens without one?

Connecticut's statutory default rules take over any issue the members never addressed in writing. Default rules cover voting, distributions, and dissolution. They assume equal standing among members, regardless of what each person contributed or negotiated informally.

Can I write my own?

A basic template can work for a simple, single-member Connecticut LLC with no partners and no outside investors. Once the LLC adds a second member, unequal contributions, or a succession plan, an attorney should review the document. A poorly written clause can create real problems later.

What is member-managed vs. manager-managed?

A member-managed Connecticut LLC gives every member authority to act for the company. A manager-managed LLC limits the authority to one or more named managers. The remaining members hold an interest without daily control. The agreement should state which structure the LLC uses.

Can the agreement override Connecticut law?

An agreement can override many statutory default rules, but not all of them. Chapter 613a protects certain provisions, including the duty of good faith, registered agent requirements, and state filing obligations. No operating agreement can waive them, regardless of what the members sign.

The Takeaway

A Connecticut LLC can operate for years without a written operating agreement, and plenty do. The gap surfaces once a bank, an investor, or a family dispute forces the question. Chapter 613a gives members wide latitude to set their internal rules. The agreement just needs to respect the handful of protected provisions the statute doesn't allow anyone to waive.

Get the agreement in writing before a disagreement, a new member, or a succession plan forces the issue. A signed document costs far less than a dispute settled by default rules nobody chose on purpose. See Best Business Structure in Connecticut for the decision made before this stage.
