Introduction
It depends on where your business is headed. An LLC and an S Corp both protect your personal assets and let profits pass through to your personal tax return. The difference comes down to ownership rules, how you pay yourself, and whether the tax savings from S Corp status are worth the added requirements.
What is an LLC?
An LLC, or Limited Liability Company, is a legal business structure that separates your personal assets from your business debts. If your business gets sued or can't pay its bills, your personal finances — your savings, your car, your home — aren't on the hook. That separation is the core reason most small business owners choose an LLC.
By default, the IRS taxes a single-member LLC as a sole proprietorship and a multi-member LLC as a partnership. That means profits and losses pass through to your personal tax return — no separate corporate tax. LLCs also have fewer ongoing requirements than corporations, which makes them easier to run year to year.
Most first-time business owners find an LLC is the right starting point. It's flexible, the ownership rules are simple, and you can always elect S Corp tax treatment later if your income grows to a point where it makes sense.
What is an S Corp?
An S Corporation is a tax classification, not a separate business entity. A business — either an LLC or a corporation — can elect S Corp status with the IRS by filing Form 2553. Once approved, profits and losses pass through to shareholders' personal returns, and the business avoids corporate-level income tax.
The main tax advantage of S Corp status is self-employment tax savings. As an LLC owner, you pay self-employment tax on all net profits. With S Corp status, you pay yourself a reasonable salary as a W-2 employee and pay self-employment taxes only on that salary. Profits above your salary are distributed to you without that additional tax. For business owners earning well above their salary, the savings can be meaningful.
The trade-off is more structure. S Corps have strict IRS eligibility rules: no more than 100 shareholders, only one class of stock, and all shareholders must be U.S. citizens or permanent residents. You'll also need to run payroll, file additional tax forms, and hold corporate formalities. That overhead is worth it at a certain income level — but not for every business.
How an LLC and S Corp compare
An LLC and an S Corp share two important features: both protect your personal assets from business liabilities, and both use pass-through taxation so the business itself doesn't pay federal income tax. Beyond that, they diverge in meaningful ways.
What they share
Limited liability protection — personal assets stay separate from business debts
Pass-through taxation — profits and losses flow to your personal tax return
No federal corporate income tax at the entity level
Credibility with banks, vendors, and clients compared to operating as a sole proprietor
Where they differ
Ownership: LLCs can have unlimited members, including other businesses and foreign nationals. S Corps are limited to 100 shareholders, all of whom must be U.S. citizens or permanent residents.
How you pay yourself: LLC owners take draws from profits. S Corp owners must pay themselves a reasonable W-2 salary before taking distributions.
Self-employment taxes: LLC owners pay self-employment tax on all net profits. S Corp owners pay it only on their salary, not on distributions above that salary.
Paperwork and formalities: LLCs have minimal ongoing requirements. S Corps require payroll, corporate minutes, and additional IRS filings.
Formation: An LLC is formed at the state level. S Corp status is a federal tax election filed with the IRS using Form 2553 — it doesn't change your state-level entity type.
Which structure is right for you?
For most people starting out, an LLC is the better first move. It's simpler to form, easier to run, and flexible enough to grow with you. If your business becomes profitable enough that the self-employment tax savings from S Corp status outweigh the added payroll and compliance costs, you can elect S Corp treatment later — you don't have to choose at formation.
A common rule of thumb: S Corp status starts making financial sense when your net profit is consistently above $40,000–$50,000 per year. Below that threshold, the cost of running payroll and filing additional forms often cancels out the tax savings. A tax professional can run the numbers for your specific situation.
If you have investors, plan to bring on foreign shareholders, or need more than one class of stock, an LLC without S Corp status gives you more flexibility. S Corp restrictions can complicate those arrangements.
FAQ
Generally, yes — but only above a certain income level. An S Corp owner pays self-employment taxes only on their W-2 salary, not on distributions above that salary. An LLC owner pays self-employment tax on all net profits. The savings are real, but they only outweigh the added payroll and compliance costs once your net profit is consistently high enough — often cited around $40,000–$50,000 per year. A tax professional can figure out the exact breakeven for your situation.
The main differences are ownership rules, how you pay yourself, and ongoing requirements. An LLC can have unlimited members, including foreign nationals and other businesses. An S Corp is limited to 100 shareholders who must all be U.S. citizens or permanent residents. LLC owners take draws; S Corp owners must pay themselves a reasonable W-2 salary. S Corps also require payroll and more IRS filings. Both offer liability protection and pass-through taxation.
It depends on your net profit. S Corp status makes the most financial sense when your business is consistently profitable enough that the self-employment tax savings exceed the cost of running payroll and meeting additional IRS requirements. Many tax professionals point to $40,000–$50,000 in annual net profit as a rough starting point. You don't need to convert your LLC — you can keep your LLC and file Form 2553 with the IRS to elect S Corp tax treatment.
It depends on your income and how much structure you want to manage. For most small businesses starting out, an LLC is the better choice — it's simpler to form, has fewer ongoing requirements, and gives you flexibility on ownership. S Corp status adds tax advantages at higher income levels, but it also adds payroll obligations and IRS compliance requirements. Many business owners start as an LLC and elect S Corp treatment once their profits make it worthwhile.
Not every business qualifies. To elect S Corp status, your business must be a domestic corporation or LLC, have no more than 100 shareholders, issue only one class of stock, and have shareholders who are all U.S. citizens or permanent residents. Certain types of businesses — including some financial institutions and insurance companies — are also ineligible. If you meet the requirements, you file Form 2553 with the IRS to make the election.
Yes. If you're an S Corp owner who works in the business, the IRS requires you to pay yourself a reasonable salary as a W-2 employee before taking distributions. The IRS watches this closely — paying yourself an artificially low salary to avoid payroll taxes is one of the most common ways S Corp owners get flagged for audit. What counts as "reasonable" depends on your industry and role. A tax professional can help you figure out the right number.
