If you’re a small business owner, you’ve likely heard the terms C Corporation and S Corporation. But what do they really mean?
Many business owners are stuck choosing between a C corporation and an S corporation, wondering which saves more on taxes, offers better protection, and suits their plans. The wrong choice can lead to double taxation, legal headaches, or missed financial opportunities.
In this blog, we break down the key differences between a C corporation and an S corporation so you can make the smart choice that fits your business goals. By the end, you’ll know which type of corporation is best for your goals.
What Is a C Corporation?
A C corporation is a type of corporation that’s legally separate from its owners. This structure is great for businesses planning to expand significantly or raise capital from investors. A C Corp can have unlimited shareholders, offer multiple stock types, and even go public.
Here’s how it works:
- The business pays taxes on its profits.
- If profits are shared with shareholders as dividends, they are taxed again. This is called double taxation.
- Owners are protected from personal liability, meaning their personal assets are safe if the business is sued.
C Corporations are best for businesses that want serious growth, plan to attract venture capital, or go global. They’re also favored because they allow foreign shareholders and flexible ownership structures.
What Is an S Corporation?
An S corporation is also a type of corporation, but it’s set up to avoid double taxation. Instead of the business paying tax, the profits “pass through” to the owners’ personal tax returns. It’s a popular choice for small and mid-sized business owners who want to save on self-employment taxes.
Key features:
- The gains and losses are channeled to shareholders.
- Owners must pay themselves a reasonable salary and report the remaining profit separately.
- No corporate tax is paid, just personal tax on income.
However, S Corps come with rules:
- Only U.S. citizens or residents can be owners.
- They can have up to 100 shareholders.
- Only one class of stock is allowed.
Many owners choose S Corps for the benefits of taxation.

Tax Implications: C Corp vs S Corp Taxes
The distinguishing feature between a C corporation and an S corporation is in the way they are taxed.
- C corporations are taxed at a flat 21% of profits levied by the federal government. Then, when dividends are paid, they are taxed again on what they are passed on to shareholders, generally at a rate of 15% or more.
- S corporations avoid this by passing their income to shareholders who are taxed at individual tax rates.
If your business earns consistent profits and you don’t need to reinvest them all, an S Corp can offer big tax savings.
Example Tax Comparison
Let’s say your business makes $200,000 in profit:
- C Corporation:
Pays $42,000 in federal income tax (21%).
If $158,000 is paid out in dividends, shareholders pay 15%, or $23,700.
Total tax = $65,700. - S Corporation:
No tax at the company level.
Owners report $200,000 on personal returns.
If taxed at 25%, that’s $50,000.
No double taxation.
C-corp vs S-corp taxes can make a huge difference depending on how much profit you plan to take home vs reinvest.

Ownership & Stock Structure
The ownership rules are very different.
- C corporations can have any number of shareholders, even from other countries. They can also offer different types of stock, like preferred and common.
- S corporations are limited to 100 U.S. owners. And they can only offer one class of stock. This limits the company’s flexibility.
This is a big reason why startups often choose C Corps; they want to raise money from many investors.
