Choosing the Right Entity Structure: LLC, S-Corp, or C-Corp?

One of the first — and most consequential — decisions a new business owner makes is how to structure their business. LLC? S-Corp? C-Corp? Sole proprietor? The options can feel overwhelming, and the stakes are real: your entity structure affects how you're taxed, how you're protected from liability, how you can raise capital, and how complex your compliance burden will be.

There's no single right answer for everyone, but there are clear patterns that make certain structures better fits depending on your situation. Here's a practical overview.

The LLC: Flexible and Simple

A Limited Liability Company (LLC) is the most common structure for small businesses — and for good reason. It's straightforward to set up, provides personal liability protection, and offers a lot of flexibility in how it's taxed. By default, a single-member LLC is taxed as a sole proprietor (income flows through to your personal return), while a multi-member LLC is taxed as a partnership. But an LLC can also elect to be taxed as an S-Corp or C-Corp if that makes more sense.

For early-stage businesses, freelancers, and consultants, an LLC offers the simplicity you need without locking you into a rigid structure. As your business grows, you have options to change how it's taxed — without reorganizing the legal entity itself.

The S-Corp: The Tax-Saver for Profitable Small Businesses

An S-Corporation is a pass-through entity — meaning the business itself doesn't pay federal income tax. Instead, profits and losses flow through to the owners' personal returns. So far, that sounds a lot like an LLC. The key difference is how self-employment taxes are handled.

When you're self-employed (or an LLC taxed as a sole proprietor), all of your net business income is subject to self-employment tax — which is 15.3% on the first roughly $160,000 and 2.9% beyond that. As an S-Corp, you're required to pay yourself a reasonable salary, which is subject to payroll taxes — but any remaining profit distributed to you as an owner is not subject to those taxes.

For a business generating $150,000 or more in net profit, the S-Corp election can save anywhere from $5,000 to $15,000+ annually in self-employment taxes, depending on the situation.

The trade-off? More compliance. An S-Corp requires running payroll, filing separate business returns, adhering to strict ownership rules (no more than 100 shareholders, all must be US citizens or residents), and maintaining corporate formalities. It also carries IRS scrutiny around what constitutes a "reasonable salary." These costs are real, but for the right business at the right income level, the savings far outweigh them.

The C-Corp: For Venture-Backed or High-Growth Businesses

A C-Corporation is its own taxpaying entity — it pays corporate income tax on its profits, and any dividends paid to shareholders are taxed again on their personal returns. This double taxation makes C-Corps less attractive for most small businesses. However, C-Corps have two significant advantages that make them the structure of choice for certain businesses.

First, they're the preferred structure for venture-backed startups. Most institutional investors require C-Corp structure because it allows for multiple classes of stock and unlimited shareholders. Second, C-Corps can retain earnings at the corporate level — rather than distributing them — which can be advantageous if the business reinvests profits heavily and the individual tax rate would be higher than the corporate rate.

For the typical small business owner, a C-Corp is unlikely to be the right starting point. But if you're building something designed to attract outside investment, it's worth understanding.

So, Which One Is Right for You?

Here's a rough framework: If you're just starting out or running a simple service business, an LLC is usually the right starting point. If your business is generating $80,000 or more in net profit and you're paying significant self-employment taxes, it's worth modeling whether an S-Corp election makes financial sense. If you're building a company you plan to take through fundraising rounds, a C-Corp is worth exploring from the start.

Entity selection isn't permanent — you can change structures as your business evolves. But the earlier you make the right choice, the more you'll save over time. If you're unsure where you stand, this is exactly the kind of conversation we have with clients every day.
