C Corporation
A C corporation is a legal business structure that exists separately from the people who own it. It counts as the default corporate structure under U.S. tax law, and most startups planning to raise outside funding choose it early on.
The name comes from Subchapter C of the Internal Revenue Code, which sets the rules for how the government taxes these businesses. That tax treatment shapes almost every other decision a company makes once it adopts this structure.
What Makes a C Corp a Separate Entity
Once a business is incorporated as a C corp, it becomes its own legal entity, distinct from its founders and shareholders. The corporation can sign contracts, own property, borrow money, and face lawsuits, all independently of the people who run it.
This separation protects the owners personally. If the company runs into debt trouble or gets sued, shareholders generally do not carry personal responsibility beyond what they already invested. Their homes, savings, and other personal assets typically stay protected.
Ownership works through shares of stock. A C corp can create multiple classes of stock, sell shares to an unlimited number of investors, and accept money from other businesses, including venture capital firms. This flexibility explains why so many startups pick this structure before their first funding round.
How the IRS Taxes a C Corporation
Taxation sets a C corp apart from nearly every other business structure, and it is the detail most business owners want to understand before choosing this path.
A C corp pays corporate income tax on its profits first. If the company later distributes some of that money to shareholders as dividends, each shareholder then pays personal income tax on the same money again.
People commonly call this double taxation. The IRS taxes the profit once at the company level and again once it reaches an individual’s tax return.
Here is how that plays out in practice. Suppose a company earns $150,000 in profit for the year. The business pays corporate tax on that full amount. If it then distributes $40,000 to shareholders as dividends, each shareholder reports that $40,000 as personal income and pays tax on it a second time.
Many startups sidestep much of this by reinvesting profits into the business instead of paying dividends. Since the company keeps that money rather than distributing it, the second layer of tax does not apply right away.
C Corp Compared to Other Business Structures
Founders often weigh a C corporation against an S corporation or an LLC before settling on a structure. Ownership goals and funding plans usually decide which one fits best.
| Feature | C Corporation | S Corporation | LLC |
|---|---|---|---|
| Taxation | Corporate tax, then shareholder tax on dividends | Pass-through to shareholders | Pass-through to members |
| Shareholder limit | Unlimited | 100 maximum | No cap, structured as members |
| Stock classes | Multiple allowed | One class only | Not applicable |
| Foreign ownership | Allowed | Not allowed | Generally allowed |
| Best suited for | Startups raising venture capital | Small businesses avoiding double tax | Businesses wanting flexibility |
Unlike S corps and LLCs, a C corp keeps its tax bill separate from its owners. The business pays corporate tax on profits no matter how it eventually distributes them.
Why Investors Lean Toward This Structure
Venture capital firms and larger institutional investors almost always expect to invest in a C corporation, often specifically one incorporated in Delaware. This preference comes down to structure and legal predictability, not tax advantages.
A handful of practical reasons drive this preference:
- C corps can issue multiple classes of stock, so investors can hold preferred shares with different rights than common shareholders get.
- The business faces no cap on shareholder count, which matters once a company raises several funding rounds.
- Foreign investors and other companies, including VC funds themselves, can hold shares directly.
- Lawyers and investors already understand the structure well, since courts and regulators have used it consistently for decades, which speeds up due diligence during fundraising.
Because of this, most startups planning to raise significant outside capital choose a C corp from day one, even knowing they accept the double taxation trade-off in exchange.
When This Structure Makes the Most Sense
A C corporation tends to fit certain businesses better than others.
- The company plans to raise venture capital or bring on institutional investors
- Ownership will likely grow past 100 shareholders over time
- The business wants to offer multiple classes of stock
- Long-term plans include going public
- The company will reinvest most profits rather than paying them out early
Businesses that do not expect outside investment, or that plan to distribute most profits to a small group of owners, often end up with a lower overall tax bill under an S corp or LLC instead.
