C Corp

C corp is the default corporate structure in the United States and the most common form used by businesses that plan to raise outside capital, issue multiple classes of stock, or eventually go public.

A C corp is formed by filing articles of incorporation with the state. Once incorporated, the business becomes a distinct legal entity, separate from its shareholders, capable of entering into contracts, owning property, and incurring liabilities in its own name.

The "C" designation is a tax classification, not a separate legal structure. Any corporation that has not elected S corporation status with the IRS is treated as a C corp by default.

How a C corp works

A C corp is created at the state level by filing articles of incorporation with the Secretary of State or equivalent agency. The corporation then issues stock to its shareholders, who become the owners of the business.

Governance follows a defined structure: shareholders elect a board of directors, which oversees major decisions and appoints officers to manage day-to-day operations. The corporate structure follows a clear hierarchy of shareholders, directors, and officers, which distinguishes it from other business entities.

For tax purposes, a C corp files its own federal income tax return (Form 1120) and pays corporate income tax at a flat 21% rate on its net income.

When profits are distributed to shareholders as dividends, shareholders may owe personal income tax on those distributions in addition to any corporate income tax already paid by the corporation. This two-level taxation is commonly referred to as double taxation.

C corps are also required to maintain ongoing compliance obligations, including adopting bylaws, holding annual shareholder meetings, issuing corporate resolutions for significant decisions, and filing annual reports with the state.

Why a C corp matters

The C corp structure is the preferred entity type for businesses seeking venture capital or planning an initial public offering (IPO). Institutional investors and venture capital firms typically require C corp status before investing, largely because of the flexibility it offers in ownership structure and stock issuance, as well as eligibility for qualified small business stock (QSBS) tax exclusions available to investors in qualifying C corporations.

Unlike other business entities, a C corp can issue multiple classes of stock, including both common and preferred, and has no limit on the number or types of shareholders. Foreign nationals, other corporations, and institutional investors can all hold shares in a C corp.

For businesses with long-term growth ambitions, the C corp structure provides a legal and financial framework that scales. It also lends credibility with lenders, partners, and enterprise clients who may view the corporate form as a signal of stability and permanence.

Common uses and examples of a C corp

C corps appear across a wide range of industries and business stages. Common scenarios include:

• Startups seeking venture funding. A technology startup that plans to raise multiple rounds of investment typically incorporates as a C corp in Delaware, where more than two-thirds of Fortune 500 companies are incorporated, to satisfy investor requirements and allow for preferred stock issuance.
• Businesses planning to go public. Any company pursuing an IPO must be structured as a C corp, as S corps and LLCs cannot list shares on public stock exchanges.
• Businesses with international or institutional shareholders. A C corp can accept investment from foreign nationals and other corporations; restrictions that apply to S corps do not apply here.
• Companies offering equity compensation. A C corp can grant stock options and restricted stock units to employees, making it a common choice for businesses competing for talent with equity-based compensation packages.

Key characteristics of a C corp

Several features distinguish a C corp from other business entities.

• Unlimited shareholders: There is no cap on the number of shareholders, and shareholders can be individuals, other corporations, or foreign nationals.
• Multiple stock classes: C corps can issue both common stock (typically with voting rights) and preferred stock (typically with dividend priority but no voting rights).
• Limited liability: Shareholders are generally not personally responsible for the corporation's debts or legal obligations.
• Perpetual existence: A C corp continues to exist regardless of changes in ownership or the death of a shareholder.
• Double taxation: Corporate income is taxed at the entity level, and the largest C corporations may also face a 15% corporate alternative minimum tax, while dividends distributed to shareholders are taxed again at the individual level.

The double taxation characteristic is the most significant trade-off of the C corp structure. However, businesses that reinvest profits rather than distributing dividends may find the impact of double taxation limited in practice, as the 21% corporate rate established by the TCJA is permanent law and applies only to net income after deductions.

C corp vs. S corp

The most common point of confusion is the distinction between a C corp and an S corp. Both are corporations formed at the state level through the same incorporation process. The difference lies in how each is taxed at the federal level.

An S corp elects pass-through taxation: income and losses flow directly to shareholders' personal tax returns, avoiding the double taxation that applies to C corps. However, S corps face significant restrictions. They are limited to 100 shareholders, all of whom must be U.S. citizens or permanent residents, and they may issue only one class of stock. A C corp carries none of these restrictions, making it the more flexible structure for businesses with complex ownership or growth plans.

Considerations and limitations

The compliance requirements of a C corp are more demanding than those of an LLC or sole proprietorship. Corporations must maintain formal records, hold regular meetings, and file annual reports. Failure to do so can jeopardize the liability protection the structure provides.

Double taxation is a real cost for C corps that distribute profits to shareholders, especially since 44 states also levy a corporate income tax in addition to the federal rate. Businesses that expect to pay out significant dividends should weigh this carefully against the structural advantages of the C corp form.

Delaware is the most common state of incorporation for C corps, with approximately 30% more corporations forming there in 2025 than in 2024, particularly for startups and investor-backed companies, due to its well-developed corporate law and Court of Chancery. However, a corporation incorporated in one state that operates in another may need to register as a foreign corporation in the states where it conducts business.

C corps are also subject to the Corporate Transparency Act, though a 2025 interim final rule removed BOI reporting requirements for U.S. companies while FinCEN finalizes updated regulations. Understanding what the Corporate Transparency Act requires is an important compliance consideration for newly formed corporations.

Related terms and next steps

Understanding the C corp structure is a starting point for making informed decisions about business formation. Several related concepts are worth exploring.

• Business entity status: Refers to the standing of a corporation with the state, including whether it is in good standing and authorized to conduct business.
• Foreign corporation: A corporation operating in a state other than the one in which it was incorporated; C corps that expand across state lines often need to register in each new state.
• Corporate Transparency Act: Federal legislation requiring many corporations to report beneficial ownership information to FinCEN.
• Indirect ownership in business: Relevant to C corps with complex ownership structures, including holding companies or tiered corporate arrangements.

Entrepreneurs deciding between a C corp, S corp, or LLC benefit from understanding how each structure affects taxation, ownership flexibility, and long-term growth options.

FAQs about C corps

Is a C corp or LLC better for a small business?

Neither structure is universally better. The right choice depends on how the business plans to grow and how profits will be used. An LLC offers simpler compliance and pass-through taxation, which benefits owners who plan to distribute profits regularly, while a C corp is the stronger choice for businesses that intend to raise outside capital, bring on institutional investors, or eventually pursue an IPO.

How does a C corp owner pay themselves?

An owner who works in the business is paid as a W-2 employee, with a salary that is deductible as a business expense at the corporate level, thereby reducing the corporation's taxable income. Profits distributed beyond that salary take the form of dividends, which are not deductible by the corporation and are taxed again on the owner's personal return, making the salary-versus-dividend balance a meaningful tax planning decision.

Can an LLC be taxed as a C corp?

An LLC is not a C corp and cannot become one without converting its legal structure, but an LLC can elect to be taxed as a corporation by filing Form 8832 with the IRS. That election changes how the entity is taxed at the federal level without altering the underlying LLC structure. The business remains an LLC under state law, with all the governance flexibility that entails, while being treated as a corporation for tax purposes.

Why do venture capital firms require C corp status?

Venture capital funds are typically structured as partnerships, and partnership tax rules create significant complications when a pass-through entity like an S corp or LLC holds equity in another pass-through entity, a problem that does not arise with C corps. Beyond the tax mechanics, C corps can issue preferred stock with the liquidation preferences, anti-dilution provisions, and other terms that institutional investors require as a condition of investment.

What happens to a C corp if a shareholder dies or leaves?

Because a C corp is a distinct legal entity, its existence is not tied to any individual shareholder. The corporation continues to operate, and the departing shareholder's stock passes to their estate or is transferred in accordance with any applicable shareholder agreement. This perpetual existence is one of the structural advantages of the corporate form over partnerships or sole proprietorships, where the departure of an owner can trigger dissolution under state law.

Does a C corp have to pay taxes if it has no profit?

A C corp with no net income owes no federal corporate income tax, since the 21% rate applies to taxable income after deductions. A corporation operating at a loss has no taxable income to assess. However, the corporation is still required to file Form 1120 with the IRS for the tax year, and it may still owe state minimum taxes or franchise fees depending on the state of incorporation, regardless of whether it turned a profit.
