Daperis CPAHow to Choose the Right Business Entity Structure
Most people pick a business structure the way they pick a phone plan: they ask a friend what they did, or they Google it at 11pm and go with whatever comes up first. There's a better way to think about it, and it really comes down to four questions, asked in this order: how much liability protection do you actually need, how do you want to be taxed, how much complexity are you willing to take on, and what does growth actually look like for you.
Start with Liability, Not Taxes
Everyone wants to jump straight to taxes. Don't. Start with liability instead, because it's the harder thing to fix after the fact.
A sole proprietorship gives you zero separation between you and the business. Sued, or can't pay a debt? Your personal assets, your car, your savings, your home, are all exposed. There's no paperwork to file, no fee, no formality, which is exactly why it's the default for anyone who hasn't filed anything else. That's fine for a genuinely low-risk situation: a side project with no employees, no contracts, nothing physical that could hurt someone. It stops being fine the moment you're signing contracts, hiring people, or handling anything with real liability exposure, food, alcohol, equipment, you name it.
An LLC puts a legal wall between you and the business. Sue the business, and in most cases only the business's assets are at risk, not yours, as long as you've actually kept the business's finances separate from your own. That separation isn't automatic, by the way. It's something you maintain, with a real business bank account and real bookkeeping, no mixing funds, no matter how tempting it is on a slow month. You should always consult a lawyer regarding any liability regarding your personal situation. It's true, lawyers are expensive, ok... they're very expensive. But good things cost money, and a good lawyer is worth every penny.
Now, How Do You Actually Want to Be Taxed?
Here's where people get tripped up: an LLC is a legal structure, not a tax structure. By default, a single-member LLC is taxed exactly like a sole proprietorship, and a multi-member LLC is taxed like a partnership. All the profit flows straight to your personal return and gets hit with self-employment tax, currently 15.3%, on top of regular income tax.
An LLC can elect to be taxed as an S-Corp instead, without changing anything about its legal structure. That's what lets you split income into salary and distributions, so only the salary portion pays self-employment tax. It's not automatic, and it's not free, you'll be running real payroll, so it usually doesn't make sense until your profit is consistently well above what a reasonable salary alone would cover, generally somewhere north of $60,000 to $80,000 for most solo operators, though your real number depends on your specific numbers.
A C-Corp is taxed as its own entity entirely, which is where the "double taxation" warnings come from: once at the corporate level, again when profits get distributed to shareholders. Almost no small business owner actually needs this structure unless they're planning to raise venture capital or bring on a large number of outside investors.
What About Complexity and Cost?
A sole proprietorship requires nothing to set up and almost nothing to maintain. LLCs require state filing, an EIN, a registered agent, and in states like Arizona, Nebraska or New York, that publication requirement (see: the world's most bureaucratic classified ad). Layer an S-Corp election on top and you're adding payroll, a separate business tax return, and a reasonable-salary number you need to be able to defend if anyone asks.
Each layer buys you something, either liability protection or tax efficiency, but it also costs you time, money, and administrative upkeep. The right structure is the one where what you're buying is actually worth what you're paying for it, given where your business is right now, not where you're hoping it'll be in three years.
And What Does Growth Change?
If you're planning to bring on partners, raise outside money, or eventually sell, that shapes the decision too. An LLC can bring on new members relatively easily. A sole proprietorship can't bring on partners at all without becoming something else entirely. Thinking about outside investors down the line? That's a conversation worth having with a CPA and an attorney before you file anything, not after.
A Simple Way to Think About It
If you're testing an idea but real income is already coming in, form the LLC now, not after your first year of "seeing how it goes." Liability exposure exists from day one, income or not. And if you're already running a profitable LLC and self-employment tax is eating a real chunk of your income every year, that's the signal to run the numbers on an S-Corp election, not some arbitrary date on the calendar.
Keep It Simple / Key Takeaway 🍕
Liability protection and tax treatment are two separate decisions that keep getting bundled into one conversation. An LLC answers the liability question. An S-Corp election, layered on top of that LLC, answers the tax question. You don't have to solve both on day one, but you should know which problem you're actually solving before you file anything.
