S-Corp vs LLC: Which is Better for Your Small Business?

Contact Us

If you own a small business, you have probably heard that forming an LLC or electing S-Corp status can save you money on taxes. But which one is actually better? The answer depends on how much your business earns, how you pay yourself, and what your long-term goals are. In this article, we are going to break down the key differences between an LLC and an S-Corp so you can make an informed decision about the best structure for your business.

So when people say LLC vs S-Corp, what they usually mean is: should my LLC be taxed as a disregarded entity/partnership, or should it elect S-Corp taxation? Let us walk through both options.

How LLCs Are Taxed by Default

When you form a single-member LLC, the IRS treats it as a disregarded entity by default. This means the business itself does not file a separate tax return — all of the income and expenses flow through to your personal tax return on Schedule C. If you have a multi-member LLC, it is taxed as a partnership by default, filing Form 1065 with each member receiving a K-1.

The key thing to understand about default LLC taxation is that all of your business profit is subject to self-employment tax (Social Security and Medicare), which is currently 15.3% on the first $176,100 of net earnings (for 2025), and 2.9% on anything above that. So if your LLC earns $200,000 in profit, you are paying self-employment tax on the entire amount — that is roughly $29,000 in self-employment tax alone, before income tax even enters the picture.

How S-Corps Are Taxed

When your LLC elects S-Corp status (by filing Form 2553 with the IRS), the tax treatment changes significantly. Your business now files its own tax return (Form 1120-S), and you, as the owner, become an employee of your own company. You pay yourself a reasonable salary through payroll, and the remaining profit can be taken as distributions.

Here is where the tax savings come in: only your salary is subject to payroll taxes (Social Security and Medicare), while your distributions are not. So using the same $200,000 example, if you pay yourself a reasonable salary of $100,000 and take the remaining $100,000 as a distribution, you have just cut your payroll/self-employment tax burden roughly in half.

Of course, the IRS requires that your salary be reasonable for the work you do — you cannot pay yourself $20,000 as the CEO of a company generating $500,000 in revenue. But with proper planning, the savings can be substantial. For a deeper look at how to determine your salary, check out our article on How Much Should My S-Corp Pay Me?

When Does the S-Corp Election Make Sense?

The S-Corp election is not right for every business. There is a general rule of thumb that it starts to make sense when your business is consistently earning more than you need to pay yourself in salary — typically when net profit exceeds roughly $60,000 to $80,000 per year. Below that threshold, the additional costs and complexity of S-Corp taxation (payroll, separate tax return, bookkeeping) may outweigh the tax savings.

Here are some signs the S-Corp election might be right for you:

• Your business consistently generates more profit than what you would pay yourself as a salary
• You are currently paying a significant amount in self-employment tax
• You are comfortable with (or willing to outsource) the added bookkeeping and payroll requirements
• You plan to stay in business for the foreseeable future — this is not a short-term side project

The Tradeoffs: What You Gain and What It Costs

The S-Corp election comes with real benefits, but also real additional responsibilities. Let us look at both sides.

Benefits of S-Corp Taxation

• Self-employment tax savings: This is the big one. By splitting your income between salary and distributions, you reduce the amount subject to payroll taxes.
• Retirement plan contributions: As a W-2 employee of your S-Corp, you can set up retirement plans like a SEP IRA or Solo 401k and make significant tax-deferred contributions. Check out our Retirement Plan Options for S-Corps article for more detail.
• Health insurance deduction: S-Corp owners can deduct health insurance premiums as an above-the-line deduction. We cover this in depth in How Do Health Insurance Benefits Work for an S Corporation?
• Credibility and structure: Running payroll and maintaining proper books adds professionalism and can make your business more attractive to lenders, partners, and potential buyers.

Additional Costs and Complexity

• Payroll: You must run payroll for yourself (and any employees), which means payroll processing, quarterly payroll tax filings, and W-2s at year end.
• Separate tax return: Your S-Corp files Form 1120-S, which is a more complex return than a Schedule C. This typically means higher tax preparation fees.
• Bookkeeping: The IRS holds S-Corps to a higher standard of recordkeeping. You need to maintain a clean balance sheet, track shareholder basis, and properly categorize salary vs. distributions.
• State-level considerations: Some states impose additional taxes or fees on S-Corps. For example, California charges a minimum $800 franchise tax plus a 1.5% S-Corp tax on net income.

A Quick Comparison

The Bottom Line

For most small business owners earning over $60,000 in profit, electing S-Corp taxation for your LLC is one of the most impactful tax strategies available. The self-employment tax savings alone can be worth thousands of dollars per year, and when combined with retirement plan contributions and health insurance deductions, the total benefit is often significant.

That said, the S-Corp election is not a set-it-and-forget-it decision. It requires ongoing compliance — payroll, bookkeeping, and a separate tax return — and the reasonable salary determination needs to be done properly to stay on the right side of the IRS. This is exactly the kind of thing a CPA who specializes in S-Corps can help you navigate.
