A partnership agreement is the written contract that two or more people running a business together use to define their contributions, ownership shares, authority, profit splits, and exit terms. Without one, your state’s default partnership statute writes those terms for you, and the defaults often ignore who put in more money, who does more work, and what each partner would have wanted when things change. A well-drafted agreement replaces those defaults with terms the partners actually negotiated.
Why Skipping the Agreement Is Expensive
When partners don’t put anything in writing, their state’s version of the Uniform Partnership Act fills in. Almost every state has adopted some form of it, and the defaults catch business owners off guard.
The biggest surprise: profits and losses split equally among all partners regardless of contribution. A partner who put in $200,000 of startup capital gets the same share as one who put in $10,000, unless a written agreement says otherwise. Hours worked don’t change the math either.
The defaults also make every partner an agent of the business. Any single partner can sign contracts, borrow money, and create obligations that bind everyone else without asking first. If your partner signs a five-year office lease you never agreed to, the partnership and potentially you personally are on the hook.
Dissolution defaults are the third landmine. Under some state versions, a partner’s death or withdrawal automatically dissolves the whole business. Revised versions are more flexible, but the statutory buyout formula rarely matches what the partners would have chosen. A written agreement rewrites all of this.
How the Partnership Type Shapes the Agreement
The structure you choose sets each partner’s baseline liability, and the agreement should reflect it.
- General partnership. Every partner faces unlimited personal liability for the business’s debts and lawsuits. Liability is joint and several, so a creditor can collect the full amount from any one partner.
- Limited partnership (LP). At least one general partner takes on full liability and manages the business. Limited partners contribute capital and share profits but are shielded from liability beyond their investment. Limited partners who get too involved in management can lose that protection, so the agreement needs to spell out what they can and cannot do.
- Limited liability partnership (LLP). All partners can participate in management, and no partner is personally liable for another partner’s negligence or misconduct. Each partner still answers for their own actions. LLPs are common in professional fields like law and accounting.
Name the structure in the agreement and spell out the rights and restrictions tied to each role.
What a Partnership Agreement Should Cover
A partnership agreement can address almost anything about the business relationship. The provisions below are the ones that matter most, and the ones where missing terms cause the most expensive disputes.
Contributions and Ownership
Document exactly what each partner is putting in: cash, equipment, real estate, client relationships, or specialized expertise. Non-cash contributions need an agreed dollar value, and significant assets justify a professional appraisal so no one argues later about what something was worth.
Clarify whether each contribution is a capital investment establishing an ownership percentage or a loan the partnership will repay with interest. That distinction affects profit allocation, tax treatment, and buyout math. If a partner brings intellectual property into the business, the agreement should say whether ownership transfers to the partnership or the partner keeps it and licenses it to the partnership. Getting this wrong turns a departure into a fight over who owns what.
Profit and Loss Allocation
Partners need to decide how profits and losses are divided. An equal split is simplest. Most partnerships tie allocation to ownership percentages or use a formula that accounts for capital contributions and active involvement.
The agreement can also set guaranteed payments, which the IRS defines as payments made to a partner “determined without regard to the partnership’s income.”1Internal Revenue Service. Publication 541 – Partnerships These function like a salary for a partner running daily operations and are paid before remaining profits are split. Guaranteed payments are taxable income to the recipient and deductible by the partnership, so they shift tax exposure in ways that matter during planning.
Specify timing. Some partnerships distribute quarterly. Others reinvest for a set period and distribute annually. Silence on timing produces fights about whether to take money out or leave it in.
Management Roles and Authority
This section prevents the daily friction that sinks partnerships. Name who handles what: one partner might run finances and vendor relationships while another oversees operations and hiring. If you’re designating a managing partner, define that role’s scope.
Give each partner a dollar limit or subject-matter boundary on binding the partnership. A common approach lets any partner sign contracts or make purchases below a threshold, say $5,000, without approval, while anything above requires a vote. Without those guardrails, you’re back to the default rule that lets any partner commit the business to anything in the ordinary course of operations.
Decision-Making Rules
Routine decisions and major strategic moves should follow different voting rules. The agreement might allow a simple majority for everyday operational choices and require unanimous consent or a supermajority of two-thirds or three-quarters for actions that fundamentally change the business: taking on significant debt, admitting a new partner, selling major assets, or changing the core business.
Deadlock provisions deserve attention. When partners split 50-50 on a critical decision, the agreement should provide a tiebreaker. Options include deferring to a designated managing partner, bringing in a neutral mediator, or triggering a buyout. Without a deadlock mechanism, a single disagreement can freeze the business.
Adding, Removing, and Buying Out Partners
For admitting new partners, specify the vote required (unanimous is common), any minimum capital contribution, and how a new partner’s arrival affects existing ownership percentages.
For voluntary withdrawals, set a required notice period, typically 60 to 180 days, so the business can arrange financing for a buyout. For involuntary removal, list specific grounds such as breach of the agreement, criminal conviction, or prolonged inability to perform duties, and define the process, including the vote threshold and the departing partner’s right to be heard.
The buyout mechanism is the most technically important piece. The agreement needs a valuation method, whether that’s book value, a multiple of earnings, an independent appraisal, or some combination. It also needs payment terms: lump sum, installments over a set period, or a structured payout tied to business performance. Vague buyout language is probably the single most litigated provision in partnership disputes, because when real money is on the table, “we’ll figure it out” stops working.
Dispute Resolution
Build a tiered clause. Require direct negotiation first, then formal mediation with a neutral mediator, and only then binding arbitration or litigation. Arbitration is faster and more private than court, but appeal rights are limited. If you pick arbitration, name the governing rules, the number of arbitrators, and who pays the costs. Mediation costs less and tends to preserve the business relationship, but it only works when both sides engage in good faith. Requiring mediation before arbitration gives partners a structured off-ramp before the process turns adversarial.
Restrictive Covenants After Departure
A departing partner who takes clients, employees, or trade secrets to a competitor can gut the business overnight. Non-compete and non-solicitation clauses address that risk, but they need careful drafting to hold up in court.
Non-compete clauses restrict a departing partner from working in the same industry within a defined geographic area for a set period. Courts evaluate them for reasonableness in three dimensions: duration, geographic reach, and how broadly the clause defines competing activity. A two-year restriction within 50 miles for a specific niche is more likely to be enforced than a five-year nationwide ban. Non-solicitation clauses are narrower and generally more enforceable: they prohibit the departing partner from poaching clients or employees without preventing them from working in the field. For many partnerships, non-solicitation alone offers enough protection without the enforceability risk that comes with a full non-compete.
Dissolution Terms
List the events that can end the partnership: mutual agreement, completion of the venture’s purpose, a vote by a specified majority, bankruptcy, or a court order. Lay out the winding-up process: who manages it, the order in which debts and obligations are paid, and how remaining assets are distributed. Clarity here prevents the partnership’s final chapter from becoming its most contentious.
Fiduciary Duties the Agreement Can’t Erase
Whether or not the agreement mentions them, partners owe each other fiduciary duties by law. These set the floor for how partners must behave.
The duty of loyalty requires each partner to put the partnership’s interests ahead of their own in business matters. No secret side deals, no siphoning partnership opportunities for personal gain, and no competing with the partnership while still a part of it. A partner who quietly diverts a client to a separate business they own is breaching this duty regardless of what’s in writing.
The duty of care requires partners to avoid grossly negligent, reckless, or intentionally harmful conduct when managing partnership affairs. The standard is not perfection. Honest mistakes and bad business judgment don’t typically create liability. A partner who signs a major contract without reading it, or ignores obvious red flags, may cross the line.
A well-drafted agreement can modify these duties to some extent, such as pre-approving specific outside business activities that would otherwise raise loyalty concerns. Most states don’t allow partners to eliminate fiduciary duties entirely. Address them explicitly so every partner understands both the baseline obligations and any agreed exceptions.
Tax Responsibilities to Assign in the Agreement
Partnerships don’t pay federal income tax themselves. The partnership’s income, deductions, credits, and losses pass through to each partner’s individual return. The partnership reports this on Form 1065 and gives each partner a Schedule K-1 showing their share.2Internal Revenue Service. Instructions for Form 1065
Form 1065 is due on the 15th day of the third month after the partnership’s tax year ends.3Internal Revenue Service. Publication 509 – Tax Calendars For calendar-year partnerships, that’s March 15. An automatic six-month extension is available by filing Form 7004, pushing the deadline to September 15. Missing the deadline triggers a penalty of $255 per partner for each month the return is late, up to 12 months.2Internal Revenue Service. Instructions for Form 1065 A four-partner partnership that files three months late owes $3,060 before anyone looks at the underlying taxes.
Each partner’s share of partnership income is subject to self-employment tax, which covers Social Security and Medicare at a combined 15.3 percent. General partners owe self-employment tax on their entire distributive share. Guaranteed payments are also subject to self-employment tax for the partner who receives them.4Internal Revenue Service. Entities 1 Limited partners generally owe self-employment tax only on guaranteed payments for services, not on their distributive share of income.
Every partnership needs its own Employer Identification Number for tax filing, opening bank accounts, and hiring employees.5Internal Revenue Service. Get an Employer Identification Number Designate in the agreement which partner is responsible for tax filings and record-keeping. When the penalty notice arrives, the IRS doesn’t care about internal disagreements over who was supposed to file.
Drafting, Signing, and Amending the Agreement
For a straightforward two-person partnership with equal contributions, a well-researched template can work as a starting point. Anything more complex, such as unequal ownership, multiple partnership types, or significant assets, warrants an attorney. Partnership attorneys typically charge between $450 and $2,500 or more for drafting or reviewing an agreement, depending on complexity and local rates. That fee looks small next to the cost of litigating a dispute a clear agreement would have prevented.
Every partner should review the draft carefully before signing, paying particular attention to buyout and dissolution provisions. Those sections feel abstract when the business is new, but they control what happens during the moments with the highest financial stakes. After signing, each partner keeps a copy. The partnership agreement is an internal document and is not filed with any government agency, though some states require separate filings like a Statement of Partnership Authority or a fictitious business name registration.
Include a process for amending the agreement. Business circumstances change, and terms that worked at launch may need updating when revenue grows, new partners join, or the business shifts direction. Requiring a unanimous or supermajority vote for amendments protects against one-sided changes while keeping the document flexible enough to evolve with the partnership.
