A general partnership is an unincorporated business that two or more people own and run together for profit, and it forms the moment they start doing so, whether or not they ever sign a document or file anything with the state. The default rules that govern it come from the Revised Uniform Partnership Act (RUPA), adopted in some form by most states. One feature defines the whole structure: every partner is personally liable for every debt the business takes on.
How the Partnership Forms
No paperwork creates a general partnership. It exists as soon as two or more people begin operating a business together for profit. A verbal deal will do it. So will conduct that looks like a shared venture, such as splitting revenue, jointly managing operations, or co-signing a lease for business space. Courts regularly find that a partnership exists even when the people involved never intended to form a legal entity.
That informality is the structure’s greatest convenience and its greatest danger. Because nothing triggers the relationship on paper, people sometimes discover they’re in a partnership only when a creditor or the IRS treats them as one. If you and a friend split the revenue from a side business, you likely have a partnership in the eyes of the law, with all the liability exposure that comes with it.
Personal Liability Is the Defining Feature
This is where general partnerships diverge most sharply from LLCs and corporations. Under RUPA’s default rules, every partner is personally liable for all partnership debts and obligations, jointly and severally. A creditor can pursue any single partner for the full amount owed, not just that partner’s proportional share. Your home, savings, car, and other personal assets are all potentially reachable if the business cannot cover what it owes.
RUPA does provide a partial safeguard called the exhaustion rule. A creditor holding a judgment against the partnership generally must try to collect from partnership assets first before going after an individual partner’s personal property. The protection has limits. A creditor can skip to personal assets if the partnership is in bankruptcy, if partnership assets are clearly insufficient, or if a court finds that requiring exhaustion of business assets would be excessively burdensome.
The practical implication is stark. If your partner commits the business to a large obligation through a bad deal or negligent conduct, creditors can come after you personally for the entire amount. The liability is not capped at your investment. Two things follow from that reality: choose partners you trust completely, and carry adequate commercial liability insurance. A general liability policy will not eliminate the legal exposure, but it absorbs the financial hit for covered claims and keeps many disputes from ever reaching personal assets.
Every Partner Can Bind the Business
Each partner is a legal agent of the partnership. When one partner acts in a way that appears to be ordinary business for the partnership, the deal binds every partner, even if the others did not know about it and would not have approved. A partner who signs a supply contract, takes out a loan, or commits the business to a service agreement can create an obligation that everyone else has to honor.
The exception is narrow: the partnership is not bound only if the partner had no actual authority to act and the third party knew that or had been notified of the restriction. In practice, outsiders almost never know about internal authority limits, so the deal usually sticks. For actions outside the partnership’s ordinary business, the other partners must authorize the deal. Where “ordinary” ends and “extraordinary” begins is decided by what businesses of the same type normally do, not what any individual partner intended.
Default Rules You Get Without an Agreement
If the partners never sign an agreement, RUPA fills every gap, and some of the defaults surprise people.
Every partner has an equal vote in managing the business, regardless of how much capital they contributed. A partner who invested $500,000 gets the same say as one who invested $5,000. Day-to-day decisions pass on a simple majority vote. Extraordinary decisions that change the fundamental nature of the business, or amend the partnership agreement itself, require unanimous consent. If three friends start a business and one funds 80% of it, that majority investor can still be outvoted 2-to-1 on routine matters unless the agreement says otherwise.
Profits are split equally among all partners, regardless of who contributed more money. Losses follow the same ratio as profits. So if three partners share profits equally, they also share losses equally, even if one partner funded the entire startup. That means the person who put in 10% of the capital would absorb a third of the losses.
What a Partnership Agreement Should Cover
A written partnership agreement is the single most valuable document the business will ever produce. It is not legally required, but it overrides nearly all of RUPA’s defaults, giving partners control over the terms that would otherwise be decided by statute. A solid agreement typically addresses:
- Capital contributions: how much each partner puts in at the start, and whether future contributions are expected.
- Profit and loss allocation: the percentage each partner receives, which can differ from ownership percentages if the partners agree.
- Management authority: who can make which decisions, and whether any partner has veto power over major actions.
- Withdrawal and buyout terms: what happens when a partner wants out, including how the departing partner’s interest is valued.
- Dispute resolution: whether disagreements go to mediation, arbitration, or court.
- Dissolution triggers: specific events that will end the partnership entirely.
Partners can also file a Statement of Partnership Authority with their state’s Secretary of State to publicly clarify who has the power to sign contracts, transfer real property, or otherwise bind the business. The filing is not mandatory in most states, but it puts third parties on notice about authority limits, which can prevent unauthorized deals from sticking.
Fiduciary Duties Partners Owe Each Other
Partners owe each other two fiduciary duties under RUPA, and courts take both seriously.
The duty of loyalty requires each partner to put the partnership’s interests ahead of personal gain in business matters. A partner cannot secretly profit from partnership transactions, compete with the partnership, or deal with the partnership while representing an adverse interest. If a partner discovers a business opportunity that falls within what the partnership does, that opportunity belongs to the partnership first.
The duty of care is a lower bar. A partner violates it only through gross negligence, reckless behavior, intentional misconduct, or knowingly breaking the law. Honest mistakes and poor business judgment, standing alone, do not breach it. Partners also owe each other a general obligation of good faith and fair dealing.
The partnership agreement can modify the scope of these duties to some extent, but most states following RUPA do not allow the agreement to eliminate them entirely. Partners can define specific categories of activities that will not violate the duty of loyalty, for instance, but they cannot strip the duty of all meaning.
How the Partnership Is Taxed
A general partnership is a pass-through entity for federal tax purposes, so the business itself does not pay income tax. Each partner’s share of profits flows through to their personal tax return, whether or not the money was actually distributed.1Internal Revenue Service. Partners Instructions for Schedule K-1 (Form 1065) You can owe tax on partnership income you never received in cash, which makes the distribution schedule a real financial planning issue.
The partnership itself files Form 1065 each year, reporting income, deductions, gains, and losses without calculating a tax bill for the business. The deadline is March 15 for calendar-year partnerships.2Internal Revenue Service. Instructions for Form 1065 Missing the deadline triggers a penalty of $255 per partner for each month the return is late, up to 12 months.3Internal Revenue Service. Failure to File Penalty The partnership issues a Schedule K-1 to each partner reporting that partner’s share of income, deductions, and credits.
General partners also owe self-employment tax on their share of partnership earnings at a combined rate of 15.3%, covering both Social Security (12.4%) and Medicare (2.9%).4Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Because the partnership does not withhold taxes from distributions the way an employer withholds from a paycheck, each partner makes quarterly estimated tax payments using Form 1040-ES.5Internal Revenue Service. Estimated Tax – Businesses Falling behind on estimated payments triggers underpayment penalties. New partners are often caught off guard by this during the first year, when they have not budgeted for tax payments on income the business retained.
Registrations That Still Apply
Forming a general partnership requires no state filing, but operating one usually involves several practical registrations.
- Employer Identification Number: the IRS requires partnerships to obtain an EIN, which functions as the business’s tax ID for filing Form 1065 and other federal returns. You will also need one to open a business bank account.6Internal Revenue Service. Get an Employer Identification Number
- Fictitious name registration: if the business operates under a name other than the partners’ legal surnames, most jurisdictions require a “Doing Business As” filing with a county clerk or state agency. These registrations typically expire after a set period and must be renewed.
- Statement of Partnership Authority: an optional filing with the Secretary of State that publicly identifies which partners can bind the business. It is particularly useful for real estate transactions, where title companies look for evidence of signing authority.
- Local licenses and permits: depending on the industry and location, the partnership may need business licenses, zoning permits, or professional certifications before it can legally operate.
One registration that general partnerships usually do not need is a Beneficial Ownership Information report with FinCEN. As of March 2025, FinCEN issued an interim rule exempting all domestic entities from BOI reporting requirements under the Corporate Transparency Act.7Financial Crimes Enforcement Network. Beneficial Ownership Information Reporting Even before that rule, most general partnerships were already exempt, because they are not created by filing a document with a secretary of state.
Leaving or Ending the Partnership
A partner leaving the business does not necessarily kill the partnership. RUPA distinguishes between dissociation (one partner departing) and dissolution (the entire business winding down). A partner can dissociate by giving notice, by dying, by going bankrupt, or through expulsion under terms set in the partnership agreement. The remaining partners can then choose to continue operating or to dissolve.
When a partner dissociates and the business continues, the partnership owes the departing partner a buyout. RUPA’s default formula values the departing partner’s interest at the amount they would have received if the firm’s assets were sold at the higher of liquidation value or going-concern value on the date of dissociation. If the departure was wrongful, the business can deduct damages from the buyout price. Most partnership agreements replace this default with a specific valuation method, such as a formula based on book value, a multiple of revenue, or an independent appraisal.
Full dissolution triggers a winding-up process. The partnership stops taking on new business and focuses on finishing existing obligations, collecting debts owed to it, and paying off creditors. Outside creditors get paid first, then partners who loaned money to the business on top of their capital contributions, and finally partners receive distributions based on their capital account balances. If assets are not enough to cover debts, partners must contribute personal funds to make up the shortfall, in proportion to their share of losses. That obligation to contribute is one more reason unlimited personal liability makes this structure riskier than an LLC or corporation.
