LLC vs. S-Corp: Which Structure Actually Saves You More?

It's the question we field more than almost any other: "Should my business be an LLC or an S-Corp?" The honest answer is that they're not even the same kind of thing — and once you understand that, the right choice gets a lot clearer.

First, the big misunderstanding

An LLC (Limited Liability Company) is a legal structure created at the state level. It separates your personal assets from your business. An S-Corp is not a legal structure at all — it's a tax election you make with the IRS. In fact, an LLC can choose to be taxed as an S-Corp. So the real question usually isn't "LLC or S-Corp," it's "should my LLC elect S-Corp tax treatment?"

How each is taxed by default

• Single-member LLC: taxed like a sole proprietorship. All profit flows to your personal return and is subject to self-employment tax (Social Security + Medicare, about 15.3%) on top of income tax.
• Multi-member LLC: taxed like a partnership — similar self-employment exposure on active income.
• LLC with S-Corp election: you become an employee of your own company. You pay yourself a reasonable salary (subject to payroll taxes), and remaining profit can be taken as distributions that are not subject to self-employment tax.

The number that usually decides it

That self-employment tax difference is where S-Corp savings come from. Here's the simplified idea: if your business nets, say, $100,000 and a reasonable salary for your role is $55,000, only that salary gets hit with payroll taxes — the remaining distribution may avoid the ~15.3% self-employment bite. That can be real money.

The costs and catches

An S-Corp election isn't free money — it comes with responsibilities:

• Reasonable compensation. The IRS requires your salary to be reasonable for the work you do. Pay yourself too little to dodge taxes and you're inviting an audit.
• Payroll. You now have to run formal payroll, file payroll tax returns, and issue yourself a W-2.
• More paperwork. A separate business return (Form 1120-S), tighter bookkeeping, and a few more compliance steps.
• Deadlines. The election (Form 2553) has timing rules, and the 1120-S is due March 15, earlier than your personal return.

So which should you choose?

If you're just starting out or your profits are modest, a simple LLC keeps life easy and cheap. As your profit grows and becomes consistent, an S-Corp election can save thousands a year — as long as the payroll and admin are handled correctly. The math is specific to your numbers, your role, and your goals.
