LLC vs S Corporation: Which Business Structure Should You Choose?
For small business owners in the United States, the choice between operating as a Limited Liability Company and electing S Corporation tax status is one of the most consequential early decisions. Both offer personal liability protection, but they differ sharply in how they handle taxation, ownership, and administrative requirements.
How Taxation Differs
An LLC is, by default, a pass-through entity. Profits flow directly to the owners' personal tax returns and are subject to self-employment tax — currently 15.3% — on the full amount. An S Corporation is also a pass-through entity, but it introduces a distinction: owners who actively work in the business must pay themselves a reasonable salary, and only that salary is subject to employment taxes. Profits distributed beyond the salary are not hit with self-employment tax.
This payroll-salary mechanism is the S Corp's primary appeal. But it comes with strings. The IRS scrutinizes what counts as "reasonable" compensation, and underpaying salary to avoid taxes invites audits and penalties. Setting up and maintaining payroll also adds accounting costs that may not be worth it for low-revenue businesses.
Ownership Rules and Administrative Burden
LLCs are far more flexible on ownership. They can have unlimited members, including foreign individuals, corporations, and trusts. S Corporations cap shareholders at 100, all of whom must be U.S. citizens or residents, and they can issue only one class of stock. These restrictions limit the S Corp's usefulness for businesses planning to raise venture capital or grant equity to international co-founders.
On the compliance side, LLCs generally have fewer formalities — no requirement for annual meetings or detailed minutes in most states. S Corporations must follow corporate formalities even if they are structured as an LLC electing S Corp status, which means board meetings, minutes, and stricter record-keeping.
Making the Choice
The deciding factor is usually math. An LLC without the S Corp election is simpler and cheaper to run. An S Corp makes sense when the business generates consistent profits well above what a reasonable salary for the owner would be — because the tax savings on distributions offset the added administrative costs. A useful rule of thumb is to model both scenarios with a tax professional before the election deadline passes.
