Key Takeaways

  • Your business entity determines how you are taxed. Choosing the right structure can save you thousands of dollars in self-employment or double taxation.
     
  • While Sole Proprietorships are the simplest to set up, LLCs and Corporations provide a corporate veil that protects your personal assets from business debts and lawsuits.
     
  • An S Corporation allows owners to split income between a reasonable salary and distributions, potentially reducing the total amount paid in social security and Medicare taxes.
     
  • C Corporations are ideal for businesses seeking venture capital or reinvesting profits, though they face double taxation on dividends paid to shareholders.
     
  • Partnerships offer shared responsibility and pass-through taxation, but they require careful structuring to avoid joint liability for a partner’s financial mistakes.

Running a business means making decisions. Some are easy. Others, not so much. Choosing how to structure your business falls into that second category.

Another term for this is selecting your business’s entity type. I want to emphasize this today because choosing the right one can change your tax life.

Sometimes, how your business is structured can mean thousands of dollars saved… or lost.

How do you choose? Well, let me tell you about the most common business entity types and what you need to know about each:

1. Sole Proprietorship

Running solo? This is the simplest setup. Just you. All the profits are yours, but so are the risks. Your business income flows directly onto your personal tax return. Easy, right? Sure—until self-employment taxes hit. 

Skip a quarterly payment, and you’ll hear from the IRS. While the simplicity is appealing, it can expose you to more risk than you might expect. Need to take out a loan? Sole proprietorships can find it harder to secure financing.

2. Limited Liability Company (LLC)

LLCs remain a popular choice, and for good reason. They offer liability protection, shielding your personal assets (your house, savings, car) if the business faces lawsuits or debt. 

By default, single-member LLCs are taxed like sole proprietorships, while multi-member ones resemble partnerships. But you can elect to be taxed as an S or C corporation, which might lower your tax bill depending on your profits. 

3. S Corporation

Want to avoid double taxation but still have liability protection? An S corp might be your answer. You pay yourself a salary (subject to employment taxes), and the remaining profits pass through as distributions, which aren’t subject to those taxes. 

It sounds like a win, but there’s a catch: you need to pay yourself a “reasonable” salary. The IRS is keeping a close eye on this, and underpaying yourself to maximize distributions can backfire. Not all businesses qualify for S corp status, and some states have their own rules and taxes, so make sure you check the specifics before making the switch.

4. C Corporation

Thinking big—venture capital, large-scale expansion? A C corp might be the ticket. Corporate tax rates are stable for now, but double taxation is still an issue: once on the business’s profits and again when dividends are paid out. 

That said, some shareholders can qualify for capital gains exclusions when selling certain stock, which can be a significant advantage for long-term planning. 

Just be careful. Many small businesses end up paying more overall due to the double tax hit. If you’re planning to reinvest profits, a C corp could work in your favor. But if you need those profits for personal use, the tax consequences can pile up fast.

5. Partnership

Going into business with someone else? A partnership might make sense. You’ll file Form 1065 and distribute K-1s to partners, with profits and losses passing through to individual tax returns. 

Sounds simple enough, until a partner racks up expenses or makes decisions that affect you financially. Partnerships also come with joint liability unless structured otherwise, which means one partner’s mistake can cost you both.

 

Final thoughts

You should never let the tax tail wag the dog of your business, and there’s a lot more to know about choosing your entity type. If you want to learn more, make some time to chat.

FAQs

“Which business structure is best for saving on taxes?”

The S Corporation is often considered the best for tax savings for profitable small businesses. By splitting business income between a reasonable salary and shareholder distributions, owners can avoid paying self-employment taxes (Social Security and Medicare) on the distribution portion of their earnings.

“What is the main difference between an LLC and a Sole Proprietorship?”

The primary difference is liability protection. A Sole Proprietorship offers no legal separation between the owner and the business, meaning personal assets are at risk. A Limited Liability Company (LLC) creates a separate legal entity that shields your personal assets from business-related lawsuits or debts.

“Do I need a C Corporation to raise venture capital?”

Yes, most venture capitalists and institutional investors prefer or require a C Corporation structure. This is because C Corps allow for multiple classes of stock, have no limit on the number of shareholders, and offer a more familiar legal framework for large-scale investment and international expansion.

“How does double taxation work for a C Corp?”

Double taxation occurs when a C Corporation pays corporate income tax on its annual profits, and then the shareholders pay personal income tax again on any dividends they receive from those remaining profits. This is a key disadvantage compared to pass-through entities like LLCs or S Corps.

“What does the IRS consider a reasonable salary for S Corp owners?”

A reasonable salary is what you would have to pay an unrelated third party to perform the same services. The IRS looks at industry standards, your duties, and the time spent on the business. Underpaying yourself just to maximize tax-free distributions is a high-risk trigger for an IRS audit.
