Being a partner means you co-own a business: you have the right to help run it, vote on its decisions, share in its profits, and inspect its records, and in exchange you owe fiduciary duties to the firm and your co-partners, carry personal responsibility for the firm’s debts, and pay tax on your share of its income whether or not any cash reaches you. The rights and duties of a partner come partly from the written partnership agreement, if there is one, and partly from the Revised Uniform Partnership Act, which supplies default rules in most states when the partners haven’t agreed otherwise. The explanation below describes a general partnership, which is the baseline. Limited partnerships and limited liability partnerships keep many of the same rules around profits, duties, and taxes, but their liability rules work differently.
Your Right to Manage and Vote
Every general partner has an equal right to take part in running the business. Under the default rules, each partner gets one vote on ordinary business decisions regardless of how much capital they put in. Someone who invested $10,000 has the same voting power as someone who contributed $200,000. A majority vote controls routine matters, such as hiring a vendor or changing business hours. Actions outside the ordinary course of business typically require unanimous consent.
Your management rights come with a corollary that cuts both ways: mutual agency. Any partner can bind the entire firm by signing a contract, leasing office space, or ordering supplies, so long as the activity looks like partnership business. A vendor dealing with one partner is generally entitled to assume that partner can act for the firm. One partner’s handshake deal becomes everyone’s obligation.
Partners who want to limit who can commit the firm to major transactions can require dual signatures above a dollar threshold or restrict individual partners to specific operational areas. Some states allow the partnership to file a public statement of authority putting third parties on notice about which partners can and cannot bind the firm, particularly for real estate transfers. Without written restrictions, the default is broad authority for everyone.
Your Right to Inspect the Books
Every partner, including former partners for the period they served, has the right to inspect and copy the partnership’s books and records during ordinary business hours. The partnership can charge a reasonable fee for copies, but it cannot deny access. This right lets you independently verify the firm’s financial health, confirm your profit distributions are accurate, and monitor how decisions are being carried out. A partnership that stonewalls information requests is usually signaling deeper trouble.
Your Share of Profits, Losses, and Guaranteed Payments
The default rule is straightforward and surprises people: partners split profits equally, and they absorb losses in the same proportion as profits. A three-person partnership where one partner put up 80% of the startup capital still splits profits three ways unless the partners agreed to a different arrangement in writing.
Partners don’t receive wages or salaries in the traditional sense. Your income comes from your distributive share of net earnings. Even if the partnership retains cash for future growth and distributes nothing, you still owe tax on your allocated share. The IRS doesn’t care whether you actually received the money.
Some partners also receive guaranteed payments, which are fixed amounts paid for services rendered or capital contributed, regardless of whether the partnership earned a profit that year. A managing partner who runs daily operations might receive $8,000 per month as a guaranteed payment on top of their profit share. The partnership deducts the payment as a business expense. The receiving partner reports it as ordinary income on Schedule E of their personal return.1Internal Revenue Service. Publication 541, Partnerships Guaranteed payments are not subject to withholding, so the partner covers the tax through quarterly estimated payments.2Office of the Law Revision Counsel. 26 U.S. Code 707 – Transactions Between Partner and Partnership
If you pay ordinary business expenses out of pocket and the partnership agreement requires you to do so, you can deduct them on Schedule E as unreimbursed partnership expenses, noted “UPE” on a separate line.3Internal Revenue Service. Instructions for Schedule E (Form 1040) The agreement must obligate you to pay. Voluntary spending on the firm’s behalf without that contractual hook doesn’t qualify.
Fiduciary Duties You Owe to the Firm and Other Partners
Partners owe each other two specific fiduciary duties, and these are legally enforceable, not just ethical expectations.
The duty of loyalty has three components. First, you must account to the firm for any profit or benefit you derive from partnership business or partnership property, including opportunities that belong to the firm. If a client offers you a side deal that grew out of your partnership work, that opportunity belongs to the partnership. Second, you cannot deal with the partnership on behalf of someone whose interests conflict with the firm’s. Third, you cannot compete with the partnership before it dissolves. A partner who secretly launches a rival business while still drawing from the firm’s profits is violating all three prongs at once.
The duty of care is a lower bar than most people assume. It does not require perfection or even good judgment. The standard prohibits grossly negligent or reckless conduct, intentional wrongdoing, and knowing violations of law. An honest but costly business decision is protected. Signing contracts without reading them, or ignoring obvious red flags, is not.
Underlying both duties is an obligation of good faith and fair dealing in every interaction related to the partnership. A written partnership agreement can define reasonable expectations around these duties and even narrow them somewhat. It cannot eliminate the duty of loyalty, cannot unreasonably reduce the duty of care, and cannot strip out the good faith obligation entirely. Those floors are non-negotiable.
Personal Liability for the Firm’s Debts
In a general partnership, every partner is jointly and severally liable for the firm’s obligations. A creditor who wins a judgment against the partnership can collect the full amount from any single partner, not just that partner’s proportional share. If the firm owes $100,000 and two of three partners are broke, the creditor can pursue the third for the entire sum. That partner can try to recover contributions from the others, but if they can’t pay, the full burden stays put.
This liability extends beyond contracts the firm signs. If one partner causes property damage or injures someone while conducting partnership business, every partner is on the hook for the resulting damages. The law treats the partner’s act as the firm’s act, and every co-owner shares the consequences.
One protection does apply. Creditors generally must exhaust the partnership’s own assets before going after individual partners’ personal property. Courts apply a doctrine called marshaling of assets, giving partnership creditors first priority on firm assets and individual creditors first priority on each partner’s personal assets. A creditor cannot skip past a partnership with a healthy bank account and seize a partner’s home. This protection breaks down when the partnership is insolvent, when the partnership is in bankruptcy, or when the partner has contractually waived the requirement.
Your Tax Obligations as a Partner
A partnership does not pay federal income tax. It files Form 1065 as an informational return, reporting total income, deductions, gains, and losses so the IRS can verify that partners are reporting their shares correctly.4Internal Revenue Service. Tax Information for Partnerships Form 1065 is due by March 15 for calendar-year partnerships, with an automatic six-month extension available on Form 7004.5Internal Revenue Service. Publication 509 (2026), Tax Calendars
Each partner receives a Schedule K-1 showing their individual share of income, deductions, and credits, which flows onto their Form 1040.4Internal Revenue Service. Tax Information for Partnerships This pass-through structure avoids the double taxation that hits corporations.
Self-Employment Tax
Your distributive share of partnership income is subject to self-employment tax, which covers Social Security and Medicare. For 2026, the combined rate is 15.3%: 12.4% for Social Security on the first $184,500 of net self-employment income, plus 2.9% for Medicare on all net self-employment income with no cap.6Internal Revenue Service. Publication 15-A (2026), Employer’s Supplemental Tax Guide If total Medicare wages and self-employment income exceed $200,000 as a single filer or $250,000 if married filing jointly, an additional 0.9% Medicare surtax applies to the amount above that threshold.7Internal Revenue Service. Questions and Answers for the Additional Medicare Tax An employee’s employer covers half of Social Security and Medicare. A partner covers the full amount, though you can deduct the employer-equivalent portion on your personal return.
Quarterly Estimated Payments
Because no one withholds income tax or self-employment tax from your partnership distributions, you make quarterly estimated tax payments to the IRS. You’re required to pay estimated taxes if you expect to owe $1,000 or more when you file.8Internal Revenue Service. Estimated Taxes The year is divided into four payment periods with separate deadlines. Missing a payment or underpaying triggers a penalty calculated on each missed period individually. Partners in their first profitable year often underestimate this and face a surprise bill the following April.
Your Right to Leave the Partnership
A partner can leave a partnership, voluntarily or involuntarily, through a process the law calls dissociation. Dissociation happens when a partner gives notice of intent to withdraw, is expelled by unanimous vote of the other partners for cause, files for personal bankruptcy, dies, or triggers any other event listed in the partnership agreement. The departure of one partner does not necessarily end the business.
If the remaining partners choose to continue, the firm must buy out the departing partner’s interest. The buyout price is based on the amount that would have been distributed to that partner if the partnership’s assets had been sold at fair market value on the date of dissociation. A departing partner loses all management rights immediately but may remain liable for partnership obligations incurred before the departure, plus obligations incurred afterward if third parties didn’t know the partner had left.
In a partnership at will, where no fixed term was set, one partner’s dissociation can trigger dissolution of the entire business. Dissolution begins a winding-up phase. The firm continues operating long enough to complete existing contracts, sell assets, collect debts owed to it, and settle liabilities. Partners can bind the firm for transactions reasonably necessary to wrap things up, but not for new ventures. On liquidation, outside creditors get paid first from partnership assets, partners then recover their capital contributions, and anything left is divided according to the profit-sharing arrangement.9Internal Revenue Service. Liquidating Distributions – Partner If assets fall short of outside debts, the partners are personally liable for the difference under the joint-and-several-liability rules that applied while the firm was operating.
Why the Written Agreement Controls
Nearly every rule above is a default that a written partnership agreement can change. Equal profit splits, one-vote-per-partner, broad authority to bind the firm, the specific triggers for dissociation: all can be rewritten to fit how the partners actually intend to operate. The limits are narrow. An agreement cannot eliminate the duty of loyalty, cannot strip out the obligation of good faith and fair dealing, and cannot reduce the duty of care below a reasonable floor. Everything else is open. Partners who rely on the defaults instead of negotiating are leaving their rights and obligations to a statute that wasn’t written with their business in mind.
