LLC vs. S-Corp in Tennessee: Which Saves You More on Taxes?

One of the most common questions we hear from Middle Tennessee business owners is simple: "Should I be an LLC or an S-corp?" It's a great question, because the answer can change your tax bill by thousands of dollars a year. The catch is that "LLC" and "S-corp" aren't actually the same kind of thing — and understanding why is the key to making the right call.

LLC vs. S-corp: what's the actual difference?

An LLC (Limited Liability Company) is a legal structure created at the state level. It protects your personal assets from business liabilities. An S-corporation is not a legal structure at all — it's a tax election you make with the IRS. That means an LLC can choose to be taxed as an S-corp. You're not picking one instead of the other; you're deciding how your LLC (or corporation) is taxed.

By default, a single-member LLC is taxed as a sole proprietorship and a multi-member LLC is taxed as a partnership. In both cases, all of the profit is subject to self-employment tax — 15.3% for Social Security and Medicare — on top of income tax. That self-employment tax is where the S-corp election can help.

How an S-corp can lower your self-employment tax

When your LLC elects S-corp status, you become an employee-owner. You pay yourself a reasonable salary (subject to payroll taxes), and the remaining profit is taken as a distribution that is not subject to the 15.3% self-employment tax. That difference is the whole reason business owners make the election.

A simplified example: say your business nets $120,000. As a default LLC, roughly all $120,000 is hit with self-employment tax. As an S-corp, you might pay yourself a $70,000 salary and take $50,000 as a distribution — and that $50,000 avoids the 15.3% tax. That's potential savings of several thousand dollars a year.

The catch: reasonable compensation and added cost

The IRS requires that your salary be "reasonable" for the work you do — you can't pay yourself $10,000 and take $110,000 in distributions to dodge payroll tax. Set the salary too low and you invite an audit; too high and you lose the benefit. Getting this number right is exactly where a CPA earns their fee.

An S-corp also adds cost and paperwork: you must run payroll, file a separate business tax return (Form 1120-S), and issue yourself a W-2 and K-1. Those costs are why the S-corp election usually makes sense only after your net profit is high enough — often somewhere around $40,000–$60,000 in net profit, though the right threshold depends on your situation.

What about Tennessee state taxes?

Tennessee has no state income tax on wages, which is great news for owners. But the state does levy a franchise and excise (F&E) tax on many entities, including LLCs and corporations. How your business is structured and taxed affects whether and how F&E applies — another reason to run the numbers with a professional before you elect.

So which should you choose?

• Stay a default LLC if your net profit is modest, you want the simplest filing, or you're just getting started.
• Consider an S-corp election once your net profit is consistently high enough that the self-employment tax savings outweigh the added payroll and filing costs.
• Always run the numbers first. The break-even point depends on your profit, your reasonable salary, and your overall tax picture.

This is not a one-size-fits-all decision, and the wrong choice leaves money on the table. If you're weighing it for your own business, we're happy to model both scenarios for you and give you a straight answer.
