An LLC is neither a corporation nor a partnership. It is its own type of legal entity, created under state law, that borrows features from both. The confusion comes from how the IRS handles taxes: for federal tax purposes, an LLC is treated as a partnership or a corporation, depending on how many owners it has and whether it files an election. But legally, it remains an LLC.
How the IRS Classifies an LLC by Default
The IRS does not have a specific tax category called “LLC.” Instead, it assigns every LLC a default classification based on the number of owners (called members).
A multi-member LLC (two or more owners) is automatically classified as a partnership for federal income tax purposes. That means the LLC itself does not pay income tax. Instead, profits and losses pass through to each member’s personal tax return. The LLC files an informational return (Form 1065), and each member receives a Schedule K-1 showing their share of the income.
A single-member LLC is treated as a “disregarded entity,” meaning the IRS essentially ignores it as a separate taxpayer. The owner reports all business income and expenses directly on their personal tax return, typically on Schedule C. For tax purposes, it works the same way a sole proprietorship does.
Neither of these defaults makes the LLC legally become a partnership or a sole proprietorship. The LLC still provides its owners with limited liability protection, which is the main reason people form one in the first place. The tax classification only determines which tax forms you file and how income flows to the owners.
An LLC Can Elect to Be Taxed as a Corporation
Any LLC can override its default classification by filing Form 8832, Entity Classification Election, with the IRS. This lets the LLC choose to be taxed as a C corporation instead. Once that election is in place, normal corporate tax rules apply: the LLC files Form 1120 (the standard corporate income tax return), the business pays corporate income tax on its profits, and any distributions to owners are taxed again on the owners’ personal returns. This is the “double taxation” structure that traditional C corporations face.
An LLC can also elect S corporation status by filing Form 2553. With this election, the LLC files Form 1120-S, and each owner reports their share of corporate income, deductions, and credits on a Schedule K-1. Like a partnership, an S corp is a pass-through entity, so the business itself generally does not pay federal income tax. The key difference from default partnership treatment is how owners who work in the business handle self-employment taxes.
Why the Tax Classification Matters
Under default partnership (or disregarded entity) treatment, all of the LLC’s net income is typically subject to self-employment tax, which covers Social Security and Medicare. For owners who actively work in the business, that can add up to a significant tax bill on top of regular income tax.
When an LLC elects S corporation treatment, owners who work in the business pay themselves a reasonable salary, and only that salary is subject to payroll taxes. Any remaining profit distributed to the owners as dividends is not subject to self-employment or payroll tax. For LLCs earning well above what a reasonable owner salary would be, this can reduce the overall tax burden.
Electing C corporation status makes less sense for most small businesses because of double taxation. However, it can be useful in specific situations, such as when the business wants to retain significant earnings at the corporate tax rate or attract certain types of investors.
Legal Structure vs. Tax Treatment
The core distinction to keep in mind is that legal formation and tax classification are two separate things. You form an LLC by filing paperwork with your state. That gives you the LLC’s legal protections: limited liability for owners, flexible management structure, and fewer formalities than a corporation. None of that changes based on how the IRS taxes you.
A partnership, by contrast, is a separate legal structure where partners are personally liable for business debts (in a general partnership). A corporation is also a separate legal structure with its own formation requirements, including a board of directors, officers, shareholder meetings, and formal bylaws. An LLC avoids most of those requirements while still letting you pick the tax treatment that works best.
So when someone says an LLC is “taxed as a partnership” or “taxed as a corporation,” they are describing the tax filing method, not the legal nature of the business. Your LLC stays an LLC regardless of which box you check on your tax forms.
How to Choose the Right Tax Election
Most LLCs stick with the default. Partnership treatment (for multi-member LLCs) or disregarded entity treatment (for single-member LLCs) is simple, avoids double taxation, and requires less paperwork. If your LLC is relatively small or you are reinvesting most of the profits back into the business, the default is usually the easiest path.
An S corporation election starts to make financial sense when the LLC’s profits are high enough that the self-employment tax savings on distributions outweigh the added costs of running payroll, filing a separate corporate return, and meeting the IRS’s “reasonable compensation” requirement for owner salaries. There is no universal income threshold where this flips, but many owners begin evaluating the switch once net profits consistently exceed $40,000 to $50,000 above what a fair salary would be.
Changing your election is not permanent. You can revoke an S corp election or change your classification again, though the IRS generally requires you to wait 60 months before switching back after a change. Filing Form 8832 or Form 2553 does not require you to dissolve your LLC or re-register with your state. You simply notify the IRS of your preferred classification, and your state-level LLC stays exactly as it was.
