LLC vs. S Corporation

LLC and S Corporation Are Not the Same Kind of Thing

This comparison trips people up because it compares two different categories. An LLC is a legal business entity you form with your state, like a corporation or a partnership. S corporation status is a federal tax election under the Internal Revenue Code, available to an eligible LLC or an eligible corporation, that changes how the IRS taxes the business. You don't form an "S corporation" with a state; you elect S corporation tax treatment for an entity you already formed, whether that's an LLC or a corporation.

Ownership Rules Differ Sharply

A default LLC has essentially no restrictions on ownership: it can have one member or many, and members can be individuals, other LLCs, corporations, trusts, or foreign persons, with ownership percentages and classes set however the operating agreement describes. An S corporation, by contrast, is restricted by the IRS to no more than 100 shareholders, who must be individuals, certain trusts, or estates, not partnerships, corporations, or nonresident aliens, and it can have only one class of stock. If your LLC's membership doesn't fit these restrictions, it can't elect S corporation status at all.

Self-Employment Tax Is the Main Reason Owners Compare Them

Under an LLC's default tax classification, disregarded entity or partnership, an active owner's full share of the business's profit is generally subject to self-employment tax, covering Social Security and Medicare. Under an S corporation election, the owner who works in the business is paid a reasonable salary through payroll, subject to payroll tax, while profit distributed beyond that salary generally isn't subject to self-employment tax. This potential savings is the main reason many profitable LLC owners consider the S corporation election.

Management and Formalities

An LLC's management is set by its operating agreement and can be as informal or as structured as the members choose; most states don't require an LLC to hold formal meetings or keep corporate-style minutes. Electing S corporation tax status doesn't change this: your LLC still operates under its own operating agreement and state LLC rules. It does add payroll obligations, since the working owner must now be paid a documented, reasonable salary rather than simply taking profit distributions whenever convenient.

An LLC Can Elect S Corporation Status and Stay an LLC

An LLC that meets the S corporation ownership requirements can file Form 2553 to elect that tax treatment while remaining an LLC under state law in every other respect: same Articles of Organization, same registered agent, same annual report obligations, same operating agreement governing management and ownership. Only the federal tax treatment of its income changes.

A Side-by-Side Comparison

S Corp Status Isn't Automatically Better

The potential self-employment tax savings come with real costs: running payroll, paying a reasonable salary (which the IRS can challenge if it's set too low), and additional tax filings. For a lower-profit LLC, the administrative cost of S corporation status can outweigh the tax savings; it tends to make more sense once profits reach a level where the savings clearly exceed the added complexity.

Check the Shareholder Restrictions Before Assuming You Qualify

If any of your LLC's members are themselves a corporation, a partnership, another LLC, or a nonresident alien, your LLC doesn't meet the S corporation ownership requirements and can't make the election, regardless of how profitable it is. Confirm every member's status against the IRS's rules before planning around an S corporation election.

State Tax Treatment of S Corporations Varies

Most states recognize the federal S corporation election for state income tax purposes, but a few states tax S corporations differently or impose an added entity-level tax. Check your specific state's treatment rather than assuming it mirrors the federal rules exactly.

Talk to a Tax Professional Before Electing

Whether S corporation status benefits your LLC depends on your profit level, how much of it you'd pay yourself as salary, and your state's specific rules. This isn't tax advice; talk to a tax professional before filing Form 2553, and before setting a salary once the election is in place, since an unreasonably low salary can draw IRS scrutiny.
