An LLC and a corporation both shield their owners from the business's debts, but they are built differently and taxed differently by default. An LLC has members and an operating agreement, no limit on the number or type of owners, and pass-through taxation: one member files Schedule C, two or more file a partnership return. A corporation has shareholders, stock, directors and officers, and is a C corporation taxed at 21 % unless it elects S status. The line between them is not fixed for tax purposes: an LLC can elect to be taxed as a C corp on Form 8832 or as an S corp on Form 2553. For a single owner with $140,000 of profit, a salary at 45% of profit where one applies and no state tax, federal tax is $34,559 as a default LLC, $29,055 as an S corp with $2,000 of costs and $38,376 as a C corp paying out all its profit.
"Limited liability corporation" is a common slip: the LLC is a limited liability company, a separate kind of entity from a corporation, created by its own state statute. Both protect personal assets from the debts of the business in the ordinary case, and both are registered with the state, but the similarities stop there. The tax default is the biggest gap, and the quick check below shows what the 21 % corporate rate followed by a dividend means on a given profit.

How the two entities are built
An LLC is formed by filing articles of organization. Its owners are members, and the IRS page on LLCs notes that most states do not restrict who they can be: individuals, corporations, other LLCs and foreign entities are allowed, and there is no maximum number. A single owner is enough. Management is set by an operating agreement, which can split profits in almost any way the members agree on. A few kinds of business, such as banks and insurance companies, generally cannot be LLCs.
A corporation is formed by filing articles of incorporation. Its owners are shareholders who exchange money or property for stock, as the IRS page on forming a corporation describes. State law then expects a structure: directors elected by the shareholders, officers appointed by the directors, bylaws, and usually meetings and minutes. Ownership is easy to transfer and divide through shares, which is why outside investors are used to corporations.
What each one costs to keep
Both pay a state filing fee to form and, in most states, a yearly or biennial report fee; some states add a franchise or minimum tax that can differ between LLCs and corporations. The state pages list the figures that were verified on the agency's site, and the LLC cost calculator adds them up over several years.
How the IRS taxes each one by default
- LLC with one member: disregarded. The profit goes on the owner's Schedule C and carries self-employment tax, as for a sole proprietor.
- LLC with two or more members: a partnership. It files Form 1065 and sends each member a K-1; members pay tax on their share.
- Corporation: a C corporation. It files Form 1120 and pays 21 %, and dividends are taxed again on the shareholders' returns.
Each default can be changed. An LLC can file Form 8832 to be classified as a corporation, or Form 2553 to be taxed as an S corporation without filing Form 8832 first. A corporation can file Form 2553 to become an S corporation if it meets the tests: 100 shareholders at most, one class of stock, only eligible owners (Instructions for Form 2553). A corporation cannot become an LLC for tax purposes; that would take a change of legal form under state law.
Four tax outcomes on the same profit
Because an LLC can choose its tax status, comparing "LLC vs corporation" really means comparing four tax treatments. The table uses a single owner, no state tax, a salary at 45% of profit for both kinds of corporation, and $2,000 of yearly payroll and filing costs for the S corp only.
| Profit | Default LLC | S corp | C corp, all paid out | C corp, all kept |
|---|---|---|---|---|
| $80,000 | $16,647 | $13,540 | $16,793 | $16,343 |
| $140,000 | $34,559 | $29,055 | $38,376 | $30,210 |
| $250,000 | $66,360 | $59,344 | $76,045 | $60,233 |
At $80,000, the lowest bill among the three that pay out their profit belongs to the LLC or corporation taxed as an S corp; at $140,000 and $250,000, to the LLC or corporation taxed as an S corp and the LLC or corporation taxed as an S corp. The C corp that keeps its profit looks competitive in the last column, but that tax is postponed rather than saved, as the C corporation guide explains. Payroll costs for the C corp and state taxes for every option are left out here; the calculator above adds your state.

Which differences matter in practice
For a freelancer or a small business owned by the people who work in it, the LLC is usually the simpler starting point: fewer formalities, pass-through taxation, and the option to elect S status later when profit justifies payroll. The LLC vs S corp calculator shows when that point comes. A corporation makes more sense from the start when the business will issue shares to investors, give stock to employees, or keep most of its profit to grow, and when the founders want the governance and share structure that buyers and funds expect.
Liability does not decide the question in most cases, since both forms offer it on the same terms in ordinary business debts. Its limits come from state law and from how the business is actually run, and they are the same kind of question for both forms; a lawyer in your state is the right person for that part.
