A partnership is a business owned and run by two or more parties who agree to share its profits and losses. Each partner contributes something (money, property, labor or expertise), and in return holds an ownership stake governed by the partnership agreement or, where no agreement exists, by state law. In the U.S., a partnership does not pay federal income tax itself. Its profits and losses pass through to the partners, who report them on their own returns.

What Is a Partnership?

The term can describe any joint venture, but in business and law it means an association of two or more persons carrying on a business for profit as co-owners.

That narrow definition has a practical consequence. In the U.S., a general partnership can exist without any filing. If two people start selling products together and split the profits as co-owners, state law may treat them as partners even if they never signed anything or called themselves partners. Limited partnerships and LLPs are different: they exist only once the partners file the required documents with the state.

Not every partner has to run the business. A silent partner contributes capital and shares in profits but stays out of day-to-day operations. The choice of form depends on how the owners want to manage the business, who will carry personal liability for its debts and how they want to be taxed.

How a Partnership Works

Most of a partnership’s mechanics are set in the partnership agreement, a contract among the partners. It typically covers:

1. Capital contributions: what each partner puts in, and whether more can be demanded later.
2. Profit and loss allocation: how results are divided. This can be equal or follow any ratio the partners agree on.
3. Management and voting: who can sign contracts, borrow money or hire staff, and which decisions require unanimous consent.
4. Compensation: whether partners who work in the business receive guaranteed payments on top of their profit share.
5. Admission, withdrawal and expulsion: how new partners join, how a departing partner is bought out, and what events justify expelling a partner.
6. Dissolution: how assets are sold and distributed if the business winds down.

If the agreement is silent on a point, the state’s partnership statute fills the gap. Under the default rules for general partnerships, profits are shared equally regardless of how much capital each partner contributed, and every partner has an equal say in management. Partners with unequal contributions therefore usually put their split in writing.

Each general partner can also act as an agent of the partnership. A contract one partner signs in the ordinary course of business generally binds the partnership, and through it, every general partner.

Types of Partnerships

General Partnership

In a general partnership, all partners share management and liability. Each partner is personally responsible for the partnership’s debts and obligations, so a creditor who cannot be paid from business assets can pursue the partners’ personal assets.

Limited Partnership (LP)

A limited partnership combines two classes of owner. At least one general partner runs the business and carries full personal liability for its debts. At least one limited partner invests capital, generally stays out of management and risks only the amount invested. LPs are widely used for investment vehicles such as private equity and real estate funds, where a sponsor acts as general partner and outside investors join as limited partners.

Limited Liability Partnership (LLP)

An LLP is a common structure for professional firms such as accounting, law and architecture practices. Its main feature is that it limits a partner’s personal liability for the misconduct of other partners. If one partner is sued for malpractice, the personal assets of the other partners are not exposed to that claim. The partner who committed the malpractice remains liable for their own actions. Some states restrict LLP status to licensed professions.

Within larger professional firms, titles add another layer. An equity partner owns a stake and shares in profits. A salaried partner (sometimes called a non-equity partner) ranks above associates but has no ownership stake and is usually paid a salary plus bonuses tied to the firm’s profits.

Limited Liability Limited Partnership (LLLP)

An LLLP is a limited partnership that also shields its general partners from personal liability for the partnership’s obligations. It combines features of LPs and LLPs. Not every state recognizes the form, and it is used far less often than the other three.

How Partnerships Are Taxed

A partnership is a pass-through entity. It files an annual information return (Form 1065) that reports its income, deductions and credits, but it pays no federal income tax itself. Each partner receives a Schedule K-1 showing their share of those items and reports that share on their own return.

Two features of this system often surprise new partners:

• Partners are taxed on their allocated share, not on cash received. If the partnership earns a profit but reinvests it instead of distributing it, partners still owe tax on their share of that profit.
• Partners are not employees. The partnership does not withhold income tax from them. General partners typically owe self-employment tax on their share of business earnings and generally need to make estimated tax payments.

The advantage over a C corporation is avoiding double taxation. A corporation pays tax on its profits, and shareholders pay tax again on the dividends they receive.

Example of a Partnership

Hypothetical example for illustration. Three people form a general partnership to run a design studio. Ana contributes $60,000, Ben contributes $30,000 and Cara contributes no cash but will work full time. Their written agreement allocates profits and losses 40% to Ana, 30% to Ben and 30% to Cara.

In its first year, the studio earns $150,000 in taxable profit. The partners distribute $60,000 in cash and keep $90,000 in the business for equipment.

Each partner reports the full taxable share on their own return, even though only part of it arrived as cash. Assumption: no guaranteed payments and no other partnership tax items.

Now suppose the studio signs a $100,000 equipment lease, the business fails and only $20,000 of assets remain. Because this is a general partnership, the lessor can generally pursue any of the three partners personally for the $80,000 shortfall, regardless of their profit split. Had the studio been organized as an LP with Ben as a limited partner, Ben’s loss would have been capped at his $30,000 investment.

Advantages and Limitations of a Partnership

Advantages

• Pooled capital and skills. Partners combine money and divide work, which matters most in the demanding startup phase.
• Shared management. Responsibility for operations is spread across people with different experience and perspective.
• Simple formation. A general partnership needs no incorporation, and partnerships avoid many corporate formalities.
• Single layer of tax. Profits are taxed only at the partner level.
• Flexible economics. Profit splits need not match capital contributions, so a partner who brings expertise instead of cash can still hold a meaningful share.

Limitations

• Personal liability. General partners can lose personal assets to business debts, including debts created by another partner acting for the business.
• Disagreement and mismanagement. More owners mean more potential for conflict, and one partner’s poor decision binds everyone.
• Difficult exits. Selling an interest requires agreement among the partners. A departing partner may not find a buyer, and remaining partners may be unable to fund a buyout.
• Tax on undistributed profits. Partners can owe tax on income they never received in cash.
• Limited access to outside capital. A partnership cannot sell shares to the public the way a corporation can.

Partnership vs. Other Business Structures

Sole proprietorship. A sole proprietorship has one owner who carries all profits and all liability. A partnership spreads both across two or more owners. Both are pass-through for tax purposes.

Limited liability company. An LLC gives all of its owners limited liability, whether or not they manage the business, while still allowing pass-through taxation. A multi-member LLC is taxed as a partnership by default. The difference is legal protection: LLC members are generally not personally liable for the company’s debts, while general partners are.

Corporation. A corporation is a separate legal entity owned by shareholders, with limited liability for its owners, a board of directors and stricter formal requirements. A C corporation pays its own income tax. Shares are generally easier to transfer than partnership interests.

LP vs. LLP. These two are frequently confused. In an LP, the split is between roles: general partners manage and carry full liability, while limited partners invest and have limited liability. In an LLP, all partners can take part in management, and the protection is mainly against liability for other partners’ actions rather than full limited liability for every obligation.

Partnership Law by Country

The basic partnership forms appear across common law jurisdictions, but the rules differ. In the U.S., partnership law is state law. Every state except Louisiana has adopted a version of the Uniform Partnership Act, which covers general partnerships and LLPs, while limited partnerships are governed by a separate uniform act. The revised act treats a partnership as a legal entity separate from its partners. In England, by contrast, a general partnership is not a separate legal entity.

FAQs

The Bottom Line

Anyone starting a business with others should decide early on a form and put the terms in writing. General partners face personal liability for business debts, including those another partner creates, so owners wanting protection can look at an LP, LLP or LLC. Partners should also plan for self-employment tax, estimated payments and tax on profits they never receive in cash.
