What Is a C Corporation?

A C Corporation is a separate legal entity owned by shareholders that offers the strongest personal liability protection of any business structure. It has a formal management structure with a board of directors and officers. C Corps are subject to corporate income tax (double taxation), but offer unlimited growth potential through stock issuance — making them the preferred structure for venture capital funding and IPOs.

Not Ideal For: Solo entrepreneurs or small local businesses with minimal funding needs.

C Corporation Tax Structure

C Corporations face double taxation: the corporation pays tax on its profits at the corporate tax rate (currently 21% federal), and shareholders pay tax again on dividends received. However, C Corps can retain earnings at potentially lower corporate rates and offer deductible benefits like health insurance for employees.

Default Tax Summaries & Frameworks

Corporate income is taxed at the entity level (21% federal). Dividends paid to shareholders are taxed again as personal income. Capital gains treatment available for stock appreciation.
