Two owners choosing between a general partnership and an LLC are not choosing a federal tax treatment; both file the same Form 1065 by default, and the IRS taxes both identically unless either affirmatively elects otherwise. What they are actually choosing is liability, state cost, and paperwork, and the gap between those three is the entire decision. A $250,000 judgment against the business shows exactly where a general partnership and an LLC diverge, and for some two-owner businesses the honest answer is that an LLC buys very little.

Same tax, different liability

A domestic LLC with two or more members is, by default, taxed as a partnership exactly like a general partnership: both file Form 1065, both pass profit and loss through to the owners' personal returns on a Schedule K-1, and both owners pay self-employment tax on their share the same way (an LLC does not change that by itself; only an S-corp election, available to either entity type with eligibility conditions, does). The tax code does not reward forming an LLC over a general partnership.

Liability is where they split. Section 306(a) of the Uniform Partnership Act (1997) makes every general partner personally liable, jointly and severally, for all obligations of the partnership, meaning a creditor can pursue any partner's personal assets, car, house, personal savings, for the full debt, regardless of which partner caused it. An LLC member's personal assets are not exposed to the LLC's debts by default; the member's loss is generally limited to what they invested, unless they personally guaranteed a loan, personally committed the wrongful act, or a court pierces the LLC's shield for not respecting its formalities.

A $250,000 judgment against the business, two owners, no insurance covering it

Say the business loses a lawsuit (a customer injury, a breached contract, a vendor's unpaid invoice that becomes a judgment) for $250,000, and the business itself has $40,000 in assets. Compare what each owner is exposed to personally under a general partnership versus an LLC with no personal guarantees signed.

Business assets applied to the judgment$40,000, in both structures
Remaining judgment after business assets$210,000, in both structures
General partnership: who owes the remaining $210,000Both partners, jointly and severally; the creditor can collect the whole $210,000 from either one's personal assets
LLC with no personal guarantee: who owes the remaining $210,000Neither member personally, assuming the LLC was properly maintained and neither member personally committed the underlying wrong

The $210,000 gap is the entire value of the LLC's liability shield in this scenario. It disappears the moment either owner signs a personal guarantee on a loan or lease, which many landlords and lenders require of a small LLC regardless of the entity's own shield, and it never existed for the general partnership in the first place.

What an LLC costs that a general partnership usually does not

Forming and maintaining an LLC is a state filing with its own ongoing cost; a general partnership, in most states, is not. California charges every LLC an annual tax of $800 regardless of income, on top of the LLC's own income-based fee at higher revenue levels, while a California general partnership generally pays nothing to the state simply for existing. Other states charge far less or nothing at all for an LLC's annual report. The exact fee and filing requirement is different in every state; llc-and-llp-filing-fees-by-state has the figures state by state rather than repeating a handful here as if they generalized.

An LLC also means more paperwork from the start: articles of organization filed with the state, an operating agreement (not always legally required, but the document that actually controls how the LLC runs), and in some states a separate annual report on top of the tax. A general partnership can exist the moment two people start sharing profits, with nothing filed anywhere, per section 202(a) of the Uniform Partnership Act, for better and for worse: nothing filed also means nothing on the public record establishing who the partners are or what they agreed to.

When an LLC is close to pointless

Where the LLC shield matters less than it looks

Situation Why the shield does less work
The business has few assets and little lawsuit exposure (a two-person consulting practice with no inventory, no physical location open to the public) There is less for a judgment to reach either way, and less for a plaintiff to sue over in the first place
Every meaningful contract requires a personal guarantee anyway (a new business's first lease, its first bank loan, often its first equipment financing) The guarantee reaches the owner's personal assets regardless of the entity type signing the contract
The owners do not maintain the LLC's formalities (separate bank accounts, separate books, actually calling it an LLC in contracts) A court asked to pierce the LLC's veil looks at exactly this, and a poorly maintained LLC can lose its shield in the one lawsuit where it mattered
The risk is professional malpractice by a licensed owner Most states' LLC statutes do not shield a professional from liability for their own malpractice regardless of the entity wrapped around the practice

None of this means an LLC is never worth it for two owners; a business with real assets, employees, customers on-site, or products that could cause harm has exactly the exposure the shield is built for, and the state fee is cheap insurance against it. It means the decision should be made on what the business actually risks, not on a general sense that an LLC is the more serious choice. How to start a business partnership covers the formation steps either way; are you liable for your business partner's debts goes further into what joint and several liability actually means for a general partner in practice.

This is general information on federal tax defaults and the uniform partnership act, not legal or tax advice for a specific business. State LLC fees, franchise taxes and filing requirements vary and change; a lawyer or accountant in the owners' state should confirm the current figures and whether an S-corp election or other structure changes the analysis.
