For a business with two or more owners, the choice between a multi-member LLC and a partnership comes down to one hard fact: the LLC protects your personal assets from business debts, and a general partnership does not. By default, the IRS taxes both structures the same way, so most co-owned businesses that have anything to lose end up choosing the LLC. The partnership route survives mainly where the owners want minimal paperwork and either have very little personal exposure or accept the risk knowingly.
The differences beyond liability are real but narrower. They cover how the entity comes into existence, how flexible its tax treatment can be, what happens when an owner leaves, and how much the state charges you every year for the privilege of operating.
The Liability Difference That Drives the Decision
Members of an LLC are not personally liable for the company’s debts or obligations. If the business gets sued or can’t pay a vendor, creditors can go after the LLC’s assets but generally cannot reach a member’s house, personal savings, or property held outside the business.1Internal Revenue Service. Limited Liability Company (LLC)
In a general partnership, every partner is personally on the hook for every partnership debt. The legal term is joint and several liability, meaning a creditor owed money by the partnership can pursue any one partner for the entire amount. If your partner signs a bad contract, or causes an accident while running a business errand, your personal savings are exposed. There is no built-in shield.
The LLC’s protection is powerful but not absolute. Courts can set it aside through a doctrine called piercing the veil when owners treat the LLC as their personal piggy bank. The usual triggers are commingling personal and business funds, failing to keep the LLC adequately capitalized, and using the entity to commit fraud. A separate business bank account and honest recordkeeping are the minimum for keeping the shield intact.
Two partnership variations exist to address the liability gap, and it’s worth knowing they don’t fully close it. A Limited Partnership has at least one general partner with full personal liability plus one or more limited partners whose exposure stops at their investment, as long as those limited partners stay out of management. A Limited Liability Partnership protects each partner from liability caused by other partners’ negligence, though the specifics vary by state. Neither gives every owner the automatic, across-the-board protection an LLC provides.
Charging Order Protection
Liability also runs in the other direction: what happens when a member’s personal creditor tries to reach into the business? If an LLC member is sued personally and loses, the creditor’s remedy in most states is limited to a charging order. That gives the creditor the right to receive distributions the debtor-member would otherwise get, but the creditor does not become a member, cannot vote, cannot see LLC records, and cannot force distributions. Under the Revised Uniform Limited Liability Company Act, the charging order is the exclusive remedy available to a judgment creditor pursuing a member’s interest.
In a general partnership, a personal creditor of one partner may have broader remedies depending on state law, including the possibility of foreclosing on the partner’s interest or forcing a liquidation. The LLC’s charging order rules make it harder for one owner’s personal troubles to blow up the whole business.
How Each One Is Formed
An LLC exists only after someone files Articles of Organization with the state’s business office and pays the filing fee. Until that filing is accepted, the LLC does not legally exist and the members have no liability protection. One-time state filing fees generally run $75 to $300.1Internal Revenue Service. Limited Liability Company (LLC)
A general partnership can form without anyone filing anything. Two or more people carrying on a business for profit are legally partners whether they set out to be or not. An informal handshake can create full partnership obligations, personal liability included, before either party realizes what happened.
A written agreement isn’t legally required for a general partnership to exist, but skipping one is reckless. Whatever the agreement doesn’t cover, state default rules will, and those defaults rarely match what the partners actually wanted. The same warning applies to an LLC’s operating agreement. Either way, the internal document is the single most important piece of paper the business will have.
How They’re Taxed
By default, the IRS treats a multi-member LLC exactly like a partnership.2Internal Revenue Service. LLC Filing as a Corporation or Partnership Both are pass-through entities, meaning the business pays no federal income tax itself. Each owner receives a Schedule K-1 reporting their share of profits, losses, deductions, and credits, and reports those amounts on a personal return. Both entities file Form 1065 as an informational return.3Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income
Active owners in either structure owe self-employment tax on their share of business income. The rate is 15.3%, split into 12.4% for Social Security and 2.9% for Medicare.4Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The Social Security portion applies only to the first $184,500 of combined earnings in 2026; the Medicare portion has no cap.5Social Security Administration. Contribution and Benefit Base Earners above $200,000 (single) or $250,000 (married filing jointly) also owe an additional 0.9% Medicare tax on the excess.6Internal Revenue Service.

Where the LLC Wins on Taxes: the S-Corp Election
An LLC can elect to be taxed as a corporation by filing Form 8832, and then elect S-corporation status by filing Form 2553.7Internal Revenue Service. About Form 8832, Entity Classification Election8Internal Revenue Service. About Form 2553, Election by a Small Business Corporation The entity keeps its LLC legal shell for liability purposes, but the IRS taxes it differently.
The election saves money by splitting business income into two buckets. Owner-employees must pay themselves a reasonable salary, which is subject to the full 15.3% in payroll taxes. Profit distributed beyond that salary is not subject to self-employment or payroll tax.9Internal Revenue Service. FS-2008-25 – Wage Compensation for S Corporation Officers For a business earning well above what the owners need as salary, the savings add up quickly.
A general partnership technically has access to the same check-the-box election rules, but this is almost never done in practice. For working purposes, treat the S-Corp election as an LLC advantage the partnership doesn’t share.
There is a cost. An LLC taxed as an S-Corp must run payroll, file quarterly payroll tax returns, and pay the owner a salary that will hold up under IRS scrutiny. If the IRS decides the salary is unreasonably low, it can reclassify distributions as wages and assess back taxes plus penalties. A partnership or default-taxed LLC skips that compliance burden entirely.
The Section 199A Deduction in 2026
Through 2025, owners of both pass-through structures could deduct up to 20% of their qualified business income under Section 199A. That deduction expired at the end of 2025 under current law.10Internal Revenue Service. Qualified Business Income Deduction11Library of Congress. Expiring Provisions of P.L. 115-97 (the Tax Cuts and Jobs Act) Congress may restore or extend it, but pass-through owners planning for 2026 should not count on it. Since both structures lose the deduction equally, the S-Corp payroll tax savings become relatively more valuable.
Where the Partnership Sometimes Wins: Debt and Basis
An owner’s tax basis controls how much loss they can deduct in a given year. In a general partnership, partners are jointly and severally liable for partnership debts, which the tax rules treat as recourse debt. That debt increases the at-risk partners’ bases and can let them write off larger losses.
In an LLC taxed as a partnership, members generally do not have personal liability for entity debts. The IRS treats that debt as nonrecourse and allocates it among all members based on profit-sharing ratios rather than who actually bears the economic risk.12eCFR. 26 CFR 1.752-2 – Partners Share of Recourse Liabilities An LLC member who hasn’t personally guaranteed any entity debt may have a lower basis than a general partner in the same economic position, which can cap how much of a loss they claim in a given year. For profitable businesses this rarely matters. For startups expecting early losses, it’s worth discussing with a tax advisor before deciding.
Management, Governance, and Bringing In Investors
An LLC’s operating agreement is essentially a blank canvas. Members can choose between member-managed (all owners participate in running the business) and manager-managed (designated managers run daily operations while other members are passive). The agreement can assign different voting weights, create classes of membership with distinct rights, allocate profits and losses in ways that don’t match ownership percentages, and set custom rules for almost every operational question.2Internal Revenue Service. LLC Filing as a Corporation or Partnership
A general partnership’s defaults under the Uniform Partnership Act are more rigid. Unless the partnership agreement says otherwise, every partner has an equal vote regardless of capital contribution, and profits and losses split equally. Major decisions like admitting a new partner often require unanimous consent. A well-drafted partnership agreement can override all of this, but partners who skip the paperwork end up with rules that treat a 90% investor the same as a 10% investor.
On the investor side, the LLC’s ability to issue different classes of membership with varying profit rights, voting rights, and liquidation preferences is common when bringing in outside money. One class might get a preferred return before other members see anything. Another might carry voting control without a proportional profit share. A partnership can accomplish some of this by careful drafting, but the framework is less intuitive and less commonly used for sophisticated investor arrangements.
Fiduciary Duties
Owners in both structures owe each other fiduciary duties, primarily the duty of loyalty (no self-dealing, no competing with the business, no siphoning opportunities) and the duty of care (no grossly negligent or reckless conduct). The difference is how much these duties can be modified. In many states, an LLC’s operating agreement can significantly narrow or even eliminate certain fiduciary duties, as long as the implied obligation of good faith and fair dealing stays in place. Partnership law tends to be less flexible: a partnership agreement can identify specific activities that don’t violate the duty of loyalty but generally cannot eliminate the core duties. If members expect to run outside ventures or have potential conflicts, the LLC’s broader flexibility here matters.
What Happens When an Owner Leaves
The default answers here diverge sharply, and they’re the reason many long-lived businesses convert away from partnership form.
Under traditional partnership law, a partner’s dissociation, voluntary or not, can trigger dissolution and winding up. In a partnership at will (no fixed term), a single partner’s notice of withdrawal can force the whole thing to dissolve. Even in a term partnership, a partner’s death or bankruptcy gives the others the right to vote on dissolution. A carefully drafted partnership agreement can override these defaults with buyout provisions, but the starting position is fragile.
Modern LLC statutes generally default to perpetual existence. A member’s departure, death, or bankruptcy does not dissolve the LLC unless the operating agreement specifically says so. The operating agreement typically includes buy-sell provisions spelling out how a departing member’s interest gets valued and purchased, letting the business continue without interruption. For businesses that rely on long-term client relationships or hold illiquid assets, that built-in continuity matters.
Ongoing Costs and Compliance
Liability protection has a price tag. Most states require LLCs to maintain a registered agent, file an annual or biennial report, and pay an annual fee or franchise tax. Annual report fees run from small amounts to several hundred dollars, and some states impose minimum franchise taxes regardless of revenue. Not enormous for a functioning business, but not zero either.
A general partnership typically faces less red tape. In many states, a general partnership that hasn’t registered as an LLP doesn’t file an annual report or pay a franchise tax. The only recurring requirement may be the informational tax return at the state level. The trade is straightforward: lower administrative costs in exchange for zero personal liability protection. For most businesses with real assets or real risk, that trade favors the LLC.
Converting an Existing Partnership to an LLC
Already operating as a general partnership and want the protection? Conversion is usually straightforward. Most states let a partnership convert directly into an LLC by filing the formation documents. The IRS generally treats the conversion as a non-event for federal tax purposes: the entity was taxed as a partnership before, the LLC defaults to partnership tax treatment, so no new election is required and no gain or loss is triggered by the conversion itself.2Internal Revenue Service. LLC Filing as a Corporation or Partnership
The practical work includes drafting an operating agreement to replace the partnership agreement, updating contracts and bank accounts to reflect the new entity name, and notifying clients, vendors, and any lenders. If the partnership holds real estate or professional licenses, check whether the state requires additional filings to transfer those into the LLC. The one-time effort is almost always worth it for the liability protection alone.
