LLC and S Corp are often compared, but they're not the same kind of thing. Here's a plain-language breakdown of how they relate, how the taxes work, and what to consider before choosing.
In This Guide
An LLC is a business structure — a legal entity formed at the state level. An S Corp is a tax classification — a way the IRS taxes your business. You can form an LLC and then elect to be taxed as an S Corp. They're not mutually exclusive, and that's the part that confuses a lot of people.
In other words, the question usually isn't "LLC or S Corp?" — it's "should my LLC keep its default tax treatment, or elect to be taxed as an S Corp?"
By default, a single-member LLC is taxed like a sole proprietorship, and a multi-member LLC is taxed like a partnership. Profits pass through to the owners' personal tax returns, and owners pay self-employment tax (Medicare and Social Security) on their share of the profits.
If an LLC elects S Corp taxation, owners who actively work in the business are treated as employees. They receive a reasonable salary (subject to payroll taxes) and take remaining profits as distributions — which are not subject to self-employment tax. This split can reduce the overall tax burden for profitable businesses.
If you decide S Corp taxation is right for you, the election is made by filing Form 2553 with the IRS. There are specific deadlines — generally early in the tax year — and rules about ownership and entity type. Because the timing and details matter, this is a step where working with a CPA or tax professional is strongly recommended.

No. An LLC is a legal business structure formed at the state level, while an S Corp is a federal tax classification. You can form an LLC and then elect S Corp taxation, but they serve different purposes — one is about legal structure, the other about how you're taxed.
Not every LLC qualifies. S Corp status has IRS rules: for example, it generally can't have more than 100 shareholders, can't have non-resident alien owners, and can't have certain entity types as owners. A tax professional can confirm whether your LLC is eligible.
There's no single number, because it depends on your salary, profits, and the cost of running payroll. Generally, the savings start to outweigh the added costs once your business is consistently profitable well beyond a reasonable salary. A CPA can run the numbers for your specific situation.
No. Your liability protection comes from being an LLC (or corporation) at the state level. Electing S Corp taxation only changes how the IRS taxes your profits — it doesn't add or remove legal protection.
It's possible to revoke an S Corp election, but there are rules and timing considerations, and it can have tax consequences. Before making or changing an election, talk to a licensed tax professional who can look at your full picture.
Yes. Your LLC already needs an EIN to open a business bank account and file taxes, and that doesn't change when you elect S Corp status. The EIN stays with your business either way.
This is general educational guidance, not legal or tax advice. S Corp elections involve specific IRS rules and deadlines — consult a licensed tax professional before making a decision.
