A partnership LLC operating agreement is the written contract among the owners of a multi-member LLC that sets ownership percentages, management authority, voting rules, how money flows in and out, what happens when a member leaves, and how disputes get resolved. It replaces the generic rules in your state’s LLC act with the terms the members actually negotiated. Most states do not require you to have one, but running a multi-member LLC without a written agreement means living with default statutory rules that rarely match what the owners intended — equal profit splits regardless of investment, any member able to bind the company, and majority admission of new owners over a minority’s objection.
Banks typically ask for the agreement before opening a business account, since it identifies who can sign on the LLC’s behalf. Lenders look for the same information when reviewing loan applications. The document itself is internal. It is not filed with the state. The signed original stays with the company’s records, and every member should hold a copy.1U.S. Small Business Administration. Basic Information About Operating Agreements
Ownership, Contributions, and Capital Accounts
Start with the members. The agreement needs each member’s full legal name and address, the exact dollar amount of any cash contribution, the appraised value of any property contributed, and the ownership percentage each contribution buys. Services can count as a contribution, but only with careful drafting. Vague descriptions like “equipment valued at fair market” invite disputes later; pin the number down at contribution and record it in that member’s capital account.
Capital accounts matter for three reasons. They fix each member’s equity stake, they feed tax reporting, and they determine what each person receives if the LLC liquidates.
Property Contributions
When a member contributes property instead of cash, the transfer to the LLC generally produces no taxable gain or loss for either side.2Office of the Law Revision Counsel. 26 USC 721 – Nonrecognition of Gain or Loss on Contribution The LLC takes the contributor’s original tax basis rather than a stepped-up fair market value, and when the LLC later sells the property, the built-in gain gets allocated back to the contributing member. Contributing appreciated property defers a tax bill. It does not erase one.
Capital Calls
Decide now whether the LLC can require additional funding later. A capital call provision should state the amount or the formula, the deadline for payment, and the consequence if a member does not pay. Dilution of the non-paying member’s percentage is the most common penalty. Some agreements add interest charges or suspend voting rights until the shortfall is cured. Without a capital call clause, the LLC has few options when it needs cash and a member refuses to put more in.
Management Structure and Voting
A multi-member LLC is either member-managed or manager-managed. In a member-managed setup, every owner can participate in running the business and bind the LLC to contracts. A manager-managed structure delegates that authority to one or more designated managers, who may or may not be members. The choice affects internal workflow and how banks, vendors, and lenders deal with the company, since outsiders need to know who can commit the LLC.
The agreement can also create officer roles such as president, secretary, or treasurer, each with defined authority. That approach works for larger LLCs where members want named individuals handling day-to-day operations without extending signing authority to everyone.
Voting Power and Thresholds
Voting power usually tracks ownership percentages. A 60% owner controls 60% of the vote. Some agreements give each member one vote regardless of stake, which protects minority owners who would otherwise have no practical influence. Either approach is legitimate; the members just need to pick one and write it down.
Spell out which decisions take a simple majority and which require a supermajority or unanimous consent. Routine spending and ordinary hiring usually need only a majority. Changes that reshape the business — amending the agreement, admitting new members, selling major assets, or taking on significant debt — generally call for higher thresholds. Clear lines prevent deadlock and keep any single member from unilaterally changing the company’s direction.
Profit and Loss Allocations
The agreement defines how profits and losses flow to each member. Most partnership LLCs allocate in proportion to ownership percentages, but the members can negotiate any split, including disproportionate allocations that reward extra labor, expertise, or risk.
The IRS will respect the allocation only if it has “substantial economic effect.” If it does not, the IRS reallocates income based on the partners’ actual economic interests.3Office of the Law Revision Counsel. 26 USC 704 – Partners Distributive Share The allocation must reflect genuine economic risk. You cannot assign 90% of losses to a 10% member just to generate deductions for that person. The capital accounts must track allocations consistently, and a member allocated losses must actually bear the economic downside.
Allocations and distributions are not the same thing. A member can be allocated $50,000 of profit for tax purposes and receive no cash if the company retains earnings. The agreement should address distribution timing, any minimum distribution to cover members’ tax liabilities on allocated income, and the order of distributions.
Tax Classification and Self-Employment Tax
By default, a multi-member LLC is treated as a partnership for federal tax purposes. The LLC itself owes no income tax. Instead, income, deductions, and credits pass through to the members on their personal returns.4Internal Revenue Service. Instructions for Form 1065 The LLC files an informational Form 1065, due March 15 for calendar-year partnerships, and issues each member a Schedule K-1 showing their share of every item.5Internal Revenue Service. Partners Instructions for Schedule K-1 Form 1065
Members can elect to be taxed as a C corporation by filing Form 8832, and with an additional S election, as an S corporation. The election requires every member’s signature and cannot be changed again for 60 months.6Internal Revenue Service. Overview of Entity Classification Regulations The operating agreement should state which classification the members have chosen and the process for changing it, since a switch affects everyone’s taxes.
Self-Employment Tax and Guaranteed Payments
A member’s share of ordinary business income is generally subject to self-employment tax, which funds Social Security and Medicare. The code excludes a limited partner’s distributive share from self-employment tax, but guaranteed payments for services — fixed payments a member receives whether or not the LLC turns a profit — remain subject to self-employment tax even for limited partners.7Office of the Law Revision Counsel. 26 USC 1402 – Definitions Describe any guaranteed payments clearly in the agreement. They are deductible by the LLC as a business expense and reported separately on the member’s K-1.8Office of the Law Revision Counsel. 26 USC 707 – Transactions Between Partner and Partnership
Fiduciary Duties
Members and managers who help run the LLC owe fiduciary duties to the company and to one another. These duties exist under state law whether or not the agreement mentions them, and most states allow the agreement to modify, though not entirely eliminate, their scope.
The duty of loyalty requires putting the LLC’s interests ahead of personal ones: no self-dealing, no taking business opportunities that belong to the company, no undisclosed competing ventures. The duty of care requires informed, reasonably prudent decisions. A well-drafted agreement handles these directly. It might waive specific conflicts of interest in advance (common when members have outside businesses in related industries), require disclosure before a vote, or set up a process for disinterested members to approve transactions that would otherwise violate the duty of loyalty. Silence leaves you with whatever your state’s default standard imposes, which may be stricter than the members actually want.
Dispute Resolution
Member disputes are where operating agreements earn their keep. Without a predetermined process, any disagreement can land in open court. A multi-step clause typically starts with mediation, which is private and cheap, and escalates to binding arbitration if mediation fails. Arbitration offers faster timelines, confidentiality, and a neutral with real business experience, but arbitration awards are very difficult to appeal.
Scope matters. A broad clause covers nearly any dispute between members, including breach of fiduciary duty, valuation fights, and deadlock. A narrow clause only reaches specified disagreements and leaves the rest to the courts. Most partnership LLCs are better served by broad language.
Buy-Sell Provisions and New Members
Buy-sell terms work as a pre-negotiated exit strategy. They cover voluntary departures, involuntary events like death or bankruptcy, and situations where members simply cannot work together anymore. A right of first refusal is the most common mechanism: before a departing member sells their interest to an outsider, the remaining members get the chance to buy at the same price and terms. That keeps strangers out of the middle of your business.
Valuation
Price is the hardest issue in any buyout. Lock in a valuation method before anyone has a reason to game the number. Options include book value (simple but often understates worth), a formula based on revenue or earnings multiples, or a professional appraisal by an independent appraiser. Many agreements make the appraiser’s determination final and binding to shut down endless re-litigation.
Admitting New Members
Adding members changes the economics for everyone. Specify the vote threshold for admission (supermajority is typical), the buy-in amount, how the new member’s capital account gets set, and whether existing percentages are diluted or adjusted. Sloppy admission terms produce arguments over what the new person paid, what they were promised, and what the existing members gave up.
Dissolution and Final Filings
When the LLC reaches the end of its life — whether by member vote, expiration of a term fixed in the agreement, or insolvency — a formal winding-up begins. The LLC stops taking new business and focuses on converting assets to cash, paying debts, and distributing what remains.
Creditors come first. State LLC statutes require it, and members cannot divide assets while the company still owes money. After debts and liquidation expenses are paid, remaining assets go to the members in proportion to their final capital account balances. A member who contributed more and took fewer distributions over the life of the business will have a larger capital account and a larger share of the remainder.
Dissolution triggers specific IRS filings. The LLC files a final Form 1065 for the closing year and checks the “final return” box; each member’s final K-1 gets marked as a final K-1.9Internal Revenue Service. Closing a Business If business property is sold during the wind-up, the LLC may need to file Form 4797. If the business itself is sold as a going concern, Form 8594 (Asset Acquisition Statement) applies. Budget for the time and professional fees these filings require.
Signing and Keeping It Current
Every member must sign the final document for it to function as a binding contract. Most states do not require notarization, but notarized signatures make it harder for anyone to later deny signing. The signed original stays with the company’s records alongside tax returns and formation documents.
This is not a set-it-and-forget-it document. Ownership changes, new capital contributions, shifts in management structure, and changes to profit splits all require formal amendments signed by whatever percentage of members the agreement itself requires. Review the agreement annually, even in quiet years, to catch small inconsistencies before they turn into real disputes.
