Partnership Agreement vs LLC Operating Agreement: Which Do You Need?

What is the difference between a partnership agreement and an operating agreement?

A partnership agreement is the contract among the partners of a general partnership, a limited partnership or a limited liability partnership. An operating agreement is the contract among the members of an LLC. Both are mostly private contracts that override the default rules in the relevant state statute, and both can be short or very detailed.

The differences that matter come from the entity, not the paperwork. An LLC gives its owners a liability shield by statute. A general partnership does not. An LLC exists because someone filed articles of organization (a certificate of formation in some states). A general partnership can exist simply because two people started doing business together for profit. Signing a partnership agreement does not create an LLC, and calling your co-owners "partners" in an LLC operating agreement does not turn the LLC into a partnership.

Can you have a partnership without a partnership agreement?

Yes, and many people do without realizing it. Texas law is a typical example: under Tex. Bus. Orgs. Code §152.051(b), an association of two or more persons to carry on a business for profit as owners creates a partnership regardless of whether they intend to create one or what they call it. Most states follow the same idea through their versions of the Uniform Partnership Act.

That means two friends who start selling products together and split the profits may already be general partners, with no written agreement and no filing. The state's default partnership rules then govern who can bind the business, how profits are shared and what happens when one wants out. Those defaults often treat partners as equal regardless of how much each contributed, which is rarely what people intend.

How does personal liability differ?

This is the main reason most small businesses choose an LLC. In a general partnership, partners are personally liable for the partnership's debts. Texas, for example, makes partners jointly and severally liable for partnership obligations under Tex. Bus. Orgs. Code §152.304, although a creditor usually has to pursue the partnership first. Joint and several means a creditor can collect the full amount from any one partner, who is then left to recover shares from the others.

In an LLC, the statute provides the shield. Delaware's version, 6 Del. C. §18-303(a), says no member or manager is personally obligated for the company's debts solely because they are a member or manager. The shield has limits: members can still be liable for their own wrongful acts, for personal guarantees they sign, and in some cases where a court disregards the company. But the starting point is the opposite of a general partnership.

A limited liability partnership or limited partnership sits in between. An LLP generally protects partners from the partnership's obligations, and a limited partnership protects its limited partners, but at least one general partner in a limited partnership is still exposed. Each of these has its own filing and its own agreement.

Is a partnership taxed differently from an LLC?

Often not. Under Treas. Reg. §301.7701-3, an LLC with two or more members is taxed as a partnership by default, so it files a partnership return and passes profit and loss through to the owners, just like a general partnership. A single-member LLC is disregarded by default. Either kind of LLC can elect to be taxed as a corporation, including as an S corporation if it qualifies.

Because the default tax treatment is usually the same, the choice between the two documents is mainly a liability and governance decision. Both agreements should still cover the tax items that cause real disputes, such as how profits and losses are allocated, whether the business must make tax distributions so owners can pay tax on allocated income, and who handles tax filings and audits.

Partnership agreement vs operating agreement: side by side

The table shows defaults. An agreement can change many of them, but it cannot give general partners a liability shield the statute does not provide.

Two practical differences are easy to miss. First, an LLC has ongoing state paperwork, such as annual or periodic reports and fees in many states, and falling behind can cost the company its good standing. A general partnership usually has fewer filings, though it may still need a business name registration and local licenses. Second, lenders and landlords often treat the two differently. They may ask LLC owners for personal guarantees precisely because the members are otherwise shielded, which narrows the practical gap between the two structures for the debts that matter most to a small business.

Can an LLC have a partnership agreement too?

Owners sometimes end up with both documents: a "partnership agreement" they signed when they first started working together, and an operating agreement they adopted after forming the LLC. That overlap causes trouble. If the two documents say different things about the profit split or what happens when someone leaves, each side will point to the version it prefers.

The fix is to make the operating agreement the single source of truth. When you form the LLC, the operating agreement should say that it is the entire agreement among the members and supersedes earlier agreements about the business, and it should carry over any earlier promises you want to keep, such as credit for money already invested or sweat equity already earned. If you want to keep a side agreement, such as a co-founder agreement about intellectual property, the operating agreement should refer to it expressly so the two documents work together instead of competing.

The same applies in reverse. A partnership that later forms an LLC to hold one asset, such as a building, may have an operating agreement for the LLC and a partnership agreement for the operating business. That can be a sensible structure, but each document should say which entity and which assets it covers.

What should both agreements cover?

Whichever document you sign, the commercial terms are almost identical. A good partnership agreement or operating agreement should answer these questions in writing.

• Who the owners are, what each contributed, and their percentage or units.
• Whether anyone can be required to contribute more money, and what happens if they cannot.
• How profits, losses and cash distributions are split, including tax distributions.
• Who manages day to day, which decisions need a vote, and what vote is needed.
• Whether owners can work on competing businesses, and the duties they owe each other.
• How the agreement can be amended, and whose consent is required.
• What happens when an owner dies, becomes disabled, divorces, leaves or wants to sell, including the buyout price and payment terms.
• How deadlocks and disputes are resolved, and how the business is wound up.

Which do you need for a two-person business?

If you have already filed articles of organization, you have an LLC and you need an operating agreement, even if you and your co-owner call each other partners. If you have not filed anything but are already running a business together for profit, you may have a general partnership, and you should either sign a partnership agreement or form an LLC and move the business into it.

For most small businesses with two or three owners, an LLC with a written operating agreement is the more common choice, because it pairs the same flexible deal terms with a liability shield. A partnership structure can still make sense for specific situations, such as professional firms that use an LLP or investment vehicles that use a limited partnership, but those choices usually involve an accountant and a lawyer.

If you do use a partnership, start from a solid form such as our free partnership agreement template and make sure it covers exits and buyouts, not only profit splits.

What if you are converting a partnership into an LLC?

Many states allow a partnership to convert into an LLC, or the partners can form a new LLC and transfer the business into it. Either way, the old partnership agreement does not automatically carry over as the operating agreement. Rewrite the terms for the LLC, using the LLC statute's vocabulary, and check that ownership percentages, capital accounts and any promises to departing partners carry across correctly.

Converting does not erase liabilities the partners already had as general partners for debts incurred before the change. Contracts, leases, bank accounts and licenses may also need to be assigned or updated to the LLC's name. A converted business is a good moment to have the new operating agreement reviewed, because terms copied from an old partnership form often leave gaps.
