LLC vs. S-Corp: Which Should Your Business Choose?

First, Clear Up the Confusion

"LLC vs. S-corp" is a confusing comparison because they aren't the same kind of thing. An LLC is a legal structure — how your business is organized and protected. An S-corp is a tax election — how your business is taxed. You can have an LLC that's taxed as an S-corp; in fact, that's a very common and very smart setup. So the real question usually isn't "LLC or S-corp," it's "should my LLC elect S-corp taxation?"

This is general information, not tax advice. The right answer depends on your income, state, and situation — confirm with your accountant.

How a Default LLC Is Taxed

By default, a single-member LLC is taxed as a sole proprietorship and a multi-member LLC as a partnership. The business itself usually pays no income tax; profits "pass through" to the owners' personal returns. The catch: all of that profit is subject to self-employment tax — 15.3% for Social Security and Medicare — on top of income tax.

How the S-Corp Election Changes the Math

When your LLC elects to be taxed as an S-corp, you become both an owner and an employee. You pay yourself a reasonable salary (subject to payroll taxes), and the remaining profit is distributed to you free of self-employment tax.

That split is the whole point. On the salary, you pay the 15.3%. On the distributions, you don't. For a profitable business, that can save thousands a year.

A Simple Example

Say your LLC nets $120,000:

• As a default LLC: roughly the full $120,000 is exposed to self-employment tax.
• As an S-corp: you might pay yourself a $70,000 reasonable salary (payroll-taxed) and take $50,000 as a distribution — sheltering that $50,000 from the 15.3%.

The savings are real, but so are the requirements.

The Catch: S-Corps Aren't Free

An S-corp election adds obligations:

• Reasonable compensation — the IRS requires your salary to be reasonable for the work you do. Pay yourself too little to dodge payroll tax and you're inviting trouble.
• Payroll — you now have to run real payroll, file payroll returns, and issue yourself a W-2.
• A separate business return — Form 1120-S, plus a K-1 to you.
• More bookkeeping — distributions, basis, and payroll all have to be tracked correctly.

Those costs and the added complexity are why the election doesn't pay off until your profit is high enough.

When Does an S-Corp Make Sense?

There's no magic number, but a common rule of thumb is that the election starts to pay once your business is consistently netting a solid five figures of profit beyond a reasonable salary — enough that the SE-tax savings on distributions outweigh the added payroll and filing costs. Below that, the simplicity of a default LLC often wins.

Don't Forget Your State

Some states tax S-corps differently, impose franchise taxes, or don't recognize the federal election the same way. The federal savings can be reduced — occasionally erased — by state rules, so the analysis has to include where you operate.

The Bottom Line

An LLC gives you legal protection; an S-corp election can cut your self-employment tax — but only when your profit is high enough to justify the payroll, filings, and bookkeeping it requires. It's one of the highest-leverage tax decisions you'll make, so it's worth running the actual numbers instead of guessing. A quick S-corp election analysis tells you whether it's worth it for your numbers.
