An LLC is neither a partnership nor a corporation. It’s a separate legal entity recognized under state law that borrows the limited liability of a corporation and the management flexibility and pass-through taxation of a partnership. So the question “is an LLC a partnership or a corporation” has a technical answer (neither) and a practical one (it can be taxed like either, and you choose). How it’s run day to day looks partnership-like; the liability shield around your personal assets is corporation-like; and the IRS, which has no tax box labeled “LLC,” slots your business into one of four existing tax categories based on your membership and any election you file.
What an LLC Actually Is
Every state treats the LLC as its own legal person, separate from the people who own it. The LLC signs its own contracts, holds its own property, and is named in its own lawsuits. Owners are called members, and they can be individuals, corporations, trusts, or other LLCs. There’s no cap on the number of members, and no requirement that members be U.S. citizens or residents.
You form one by filing Articles of Organization (or a Certificate of Organization) with your state and getting an Employer Identification Number from the IRS to use as the business’s tax ID.1Internal Revenue Service. Get an Employer Identification Number The internal rulebook is the Operating Agreement, which lets members customize how profits are split, who has authority, what happens when someone leaves, and how disputes get resolved.2U.S. Small Business Administration. Basic Information About Operating Agreements Skip the Operating Agreement and your state’s default LLC rules fill the gaps, which may not match what you actually want.
A member’s ownership stake is personal property, not a direct claim on the LLC’s assets. If a member faces personal creditors or walks away, the LLC’s property stays with the LLC.
Where an LLC Looks Like a Partnership
Running an LLC feels a lot like running a partnership. Most LLCs are member-managed by default, meaning every member has authority to make decisions and sign contracts for the business, the way general partners share equal control. There’s no board of directors, no required officer titles, and no formal chain of command unless members build one into the Operating Agreement.
The paperwork is lighter than a corporation’s. States don’t require LLCs to hold annual meetings or keep formal minutes. A two-member LLC can decide things over a phone call rather than scheduling a board meeting and drafting resolutions afterward. Documenting major decisions in writing is still smart practice for protecting your liability shield, but the law doesn’t force it.
Profits and losses flow through to members the same way partnership income flows to partners. By default there’s no entity-level income tax. Each member reports their share on a personal return, and the LLC files only an informational return.
Where an LLC Looks Like a Corporation
The feature that pulls an LLC away from a general partnership is limited liability. If the business is sued or defaults on a debt, creditors can reach the LLC’s assets but generally cannot reach the members’ personal bank accounts, homes, or other property. General partners get no such protection; they’re personally on the hook for everything the partnership owes. The liability shield around LLC members is the same basic concept that protects corporate shareholders, and it’s the main reason people form LLCs instead of operating as partnerships.
An LLC can also mimic corporate structure by electing to be manager-managed. The members appoint one or more managers to handle operations, and the rest take a passive investor role. The managers function like corporate officers, running the company without needing sign-off from every member on routine calls. This suits LLCs with outside investors who put in capital but don’t want to be involved day to day.
How the IRS Classifies an LLC
The IRS has no tax classification called “LLC.” It drops every LLC into an existing category. The default depends on how many members you have, and you can override the default by filing an election.
Single-Member LLC: Disregarded Entity
A single-member LLC is a “disregarded entity” for federal income tax. The IRS pretends the LLC isn’t there and you report business income and expenses on Schedule C of your personal Form 1040, exactly like a sole proprietor.3Internal Revenue Service. Single Member Limited Liability Companies You still keep your state-law liability protection. “Disregarded” only describes the tax filing; the LLC remains a separate legal entity.
Multi-Member LLC: Partnership by Default
An LLC with two or more members defaults to partnership taxation. The LLC files Form 1065 as an informational return and pays no income tax itself. Each member gets a Schedule K-1 showing their share of profits, losses, and deductions, and reports those amounts on a personal return.4Internal Revenue Service. LLC Filing as a Corporation or Partnership How profits are split follows the Operating Agreement. Without one, most states divide profits equally among members regardless of what each person put in.
S-Corporation Election
An LLC can elect S-Corp tax treatment by filing Form 2553. The LLC stays an LLC under state law; the IRS just taxes it like an S-Corp. The appeal is cutting self-employment tax.5Internal Revenue Service. S Corporations
You split the LLC’s income in two. The first bucket is a reasonable salary paid to you as an employee, subject to payroll taxes (the same 15.3%, split between employer and employee portions). The second bucket is the remaining profit, distributed to you as a shareholder, subject to income tax but not self-employment or payroll tax. If the LLC earns $200,000 and a reasonable salary for your role is $90,000, you pay payroll tax on $90,000 but not on the $110,000 in distributions.
The IRS watches this closely. Courts have consistently required shareholder-employees to take reasonable compensation for the work they actually do, and artificially low salaries get struck down.6Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers “Reasonable” generally means what someone in a similar role at a similar company would earn. Set the salary too low and the IRS can reclassify distributions as wages, with back taxes, penalties, and interest.
To qualify, the LLC must have no more than 100 shareholders, all U.S. citizens or residents (or certain qualifying trusts and estates). Partnerships, corporations, and nonresident aliens can’t be shareholders, and the LLC can have only one class of ownership interest.5Internal Revenue Service. S Corporations If any of your members are other businesses or foreign nationals, S-Corp status is off the table.
C-Corporation Election
An LLC can elect C-Corp taxation by filing Form 8832. The election can take effect up to 75 days before the filing date or up to 12 months after.7Internal Revenue Service. About Form 8832, Entity Classification Election
Under C-Corp taxation, the LLC pays a flat 21% federal tax on profits at the entity level.8Office of the Law Revision Counsel. 26 USC 11 – Tax Imposed If after-tax profits are distributed to members as dividends, members pay tax again on the dividends at their personal rate. That’s double taxation, and it’s the defining downside.
Why pick it anyway? If the business plans to reinvest most of its profits rather than distribute them, the 21% flat rate can be lower than the combined income and self-employment tax members would pay under pass-through treatment. C-Corp status also drops the S-Corp shareholder restrictions, so foreign investors and other business entities can be members. Some fringe benefits, including employer-paid health insurance and certain retirement plan contributions, can be more tax-advantageous as well. For businesses that pay out most earnings to owners each year, though, C-Corp taxation almost always costs more.
The Self-Employment Tax Catch
Pass-through taxation has a cost that catches new LLC members off guard. Because members aren’t employees of the business, their share of profits is generally subject to self-employment tax, which covers the Social Security and Medicare contributions an employer would otherwise split with you.
The combined rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.9Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The Social Security portion applies only to the first $184,500 of net earnings in 2026.10Social Security Administration. Contribution and Benefit Base Medicare has no cap, and if your self-employment income tops $200,000 ($250,000 for married filing jointly), an additional 0.9% Medicare surtax applies above that threshold.
You can deduct the employer-equivalent half of self-employment tax (7.65%) when calculating adjusted gross income. That deduction lowers your income tax, not the self-employment tax itself. For a profitable LLC, self-employment tax often runs higher than income tax each year, which is why the S-Corp election exists.
Keeping the Liability Shield Intact
Limited liability isn’t automatic just because your state approved your Articles of Organization. Courts can “pierce the veil” and hold members personally responsible for the LLC’s debts when the business isn’t treated as a genuinely separate entity.11LII / Legal Information Institute. Piercing the Corporate Veil The behaviors that trigger veil-piercing are consistent across most states:
- Commingling funds. Using the LLC’s bank account for personal expenses, or paying business costs from a personal card, is the fastest way to lose protection. When a court sees money moving freely between personal and business accounts, it treats the LLC as an extension of the owner.
- Undercapitalization. Starting the LLC with too little money or assets to realistically cover its obligations. If the business was never funded enough to operate on its own, courts may conclude it was just a shell.
- Fraud or misrepresentation. Using the LLC to deceive creditors or dodge existing obligations. Courts uniformly refuse to let the LLC form serve as a tool for fraud.
The practical steps are simple: keep a separate business bank account, keep personal spending out of it, document major decisions in writing, file annual state reports on time, and fund the LLC adequately for what it takes on. None of it is hard, but skipping any of it creates the opening a creditor needs to reach your personal assets, and that’s the one thing the LLC form was built to prevent.
