A corporation is a business that has been formally registered with a state government and, as a result, exists as its own legal entity, separate from the people who own or run it. That separation is the defining feature of the corporate form: the business can own property, sign contracts, borrow money, sue, and be sued entirely in its own name. Its owners’ personal assets sit outside the business and are generally protected from its debts and legal liabilities.
A Separate Legal Person Under State Law
A corporation comes into existence the moment its founding document is filed with the state. In Delaware, filing a certificate of incorporation with the Division of Corporations transforms the people behind the business into a “body corporate” under the law.1Delaware Code Online. Delaware Code 8 – General Corporation Law – Section 106 Other states use the term “articles of incorporation,” but the effect is the same. From that filing forward, the corporation owns its own assets, carries its own debts, and answers for its own actions.
This separation is often called the corporate veil. If the business is sued or cannot pay its creditors, those creditors can generally reach only the corporation’s assets. The founders’ homes, savings, and other personal property sit behind the veil. That protection is a major reason the corporate form became dominant once businesses started needing large pools of capital from investors who had no role in daily operations.
Corporations also have perpetual existence by default. Unlike a partnership that may dissolve when a partner dies or leaves, a corporation continues indefinitely unless its founding document specifies a limited duration or the owners decide to wind it down.2Delaware Code Online. Delaware Code 8 – General Corporation Law – Section 122 Shares change hands without interrupting the entity, which makes the corporate form well suited to businesses that need to outlast their founders.
Because it is a legal person, a corporation can execute binding contracts, hold real estate, issue bonds, and file lawsuits in its own name. It also bears its own legal obligations, including paying taxes and complying with regulations. When a corporation breaks the law, courts can impose fines and civil judgments against the entity itself.
Who Owns and Runs a Corporation
Three roles define how a corporation is owned, governed, and operated, and the separation between them is what makes the corporate form different from a partnership or sole proprietorship.
Shareholders are the owners. They contribute capital in exchange for stock and hold the right to vote on major corporate matters, including electing the board of directors.3Investor.gov. Shareholder Voting Shareholders generally do not manage the business. Their power is exercised through the ballot, and their financial risk is limited to what they invested.
Directors are the governing body. State corporation laws place responsibility for managing the business and its affairs on the board.4Delaware Code Online. Delaware Code 8 – General Corporation Law – Section 141 Directors set strategy, approve major transactions, and oversee compliance. They owe the corporation two core duties: a duty of loyalty, which means putting the corporation’s interests ahead of their own and disclosing conflicts, and a duty of care, which means making informed decisions after reviewing the relevant information. Directors who breach these duties can face personal liability even though the corporation itself is a separate entity.
Officers are the executives. The CEO, CFO, secretary, and other appointed leaders act as agents of the corporation, executing the board’s directives and running daily operations. This three-tier structure is what allows a corporation to have thousands of passive investors while a small board provides oversight and a handful of officers keeps the business running.
Types of Corporations
The word “corporation” covers several distinct legal structures, each with different tax treatment and operational rules.
C-Corporations
A C-corporation is the default corporate structure. It pays federal income tax on its own profits at a flat rate of 21 percent.5Office of the Law Revision Counsel. 26 U.S. Code 11 – Tax Imposed The catch is what is commonly called double taxation: after the corporation pays tax on its earnings, any profits distributed to shareholders as dividends are taxed again on each shareholder’s personal return.6Office of the Law Revision Counsel. 26 USC 301 – Distributions of Property Depending on the shareholder’s income, qualified dividends face a rate of up to 23.8 percent including the net investment income tax. For a dollar of corporate profit, the combined effective rate can approach 40 percent after both layers of tax. Despite this cost, C-corporations remain the structure of choice for companies that plan to go public or raise venture capital, because there are no restrictions on the number or type of shareholders and multiple classes of stock can be issued.
S-Corporations
An S-corporation avoids double taxation by passing income, losses, deductions, and credits directly through to shareholders, who report them on their personal tax returns.7Internal Revenue Service. S Corporations The corporation itself generally pays no federal income tax. The trade-off is strict eligibility. The business must be a domestic corporation with no more than 100 shareholders, and every shareholder must be a U.S. citizen or resident individual, an estate, or certain trusts. Non-resident aliens, other corporations, and partnerships cannot hold shares. The company can issue only one class of stock, though differences in voting rights among common shares are permitted.8Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined Any violation of these requirements can cause the S-election to be revoked, retroactively subjecting the corporation to C-corp taxation.
Nonprofit Corporations
A nonprofit corporation organizes around a charitable, religious, educational, scientific, literary, or similar exempt purpose rather than generating profit for owners.9Internal Revenue Service. Exempt Purposes – Internal Revenue Code Section 501(c)(3) If the IRS grants tax-exempt status under Section 501(c)(3), the organization pays no federal income tax on revenue related to its mission. The critical restriction is that no part of the corporation’s net earnings may benefit any private shareholder or individual.10Internal Revenue Service. Inurement/Private Benefit – Charitable Organizations Employees can receive reasonable compensation, but surplus revenue must be reinvested in the exempt purpose. Violating the private inurement prohibition can result in loss of tax-exempt status.
Benefit Corporations
A benefit corporation is a relatively new for-profit structure, now available in over 40 states, that legally requires directors to weigh the impact of their decisions on workers, the community, and the environment alongside shareholder profits. Traditional corporate law focuses director duty on shareholder value. Benefit corporation statutes expand that duty to broader stakeholders and typically require an annual benefit report measured against a third-party standard. Founders choose this structure when they want social or environmental goals embedded in the corporate charter rather than treated as optional.
Articles of Incorporation and Bylaws
Two documents form the foundation of every corporation. The articles (or certificate) of incorporation is the public filing. It contains the corporation’s name, the name and address of its registered agent, the types of stock the corporation is authorized to issue, and the incorporator’s name.11Delaware Code Online. Delaware Code 8 – General Corporation Law – Section 102 State law imposes specific naming requirements, such as including a word like “Corporation,” “Incorporated,” or an abbreviation like “Inc.” in the entity name.
Bylaws are the internal rulebook. They are not filed with the state and are generally not public, but they govern day-to-day operations: how many directors serve on the board, how they are elected and removed, how meetings are called and conducted, what constitutes a quorum, how officers are appointed, and how the bylaws themselves can be amended. Well-drafted bylaws prevent disputes by spelling out decision-making procedures before disagreements arise.
Keeping a Corporation in Good Standing
Forming a corporation is only the first step. Keeping it in good standing and preserving the liability shield requires ongoing compliance.
- Every corporation needs an Employer Identification Number from the IRS, obtained by filing Form SS-4. The EIN is required for tax returns, bank accounts, and payroll.12Internal Revenue Service. Application for Employer Identification Number (Form SS-4)
- Most states require annual or biennial reports updating basic information such as directors and the principal office. Fees vary by state.
- Every state requires a registered agent, a designated person or company authorized to receive legal documents on behalf of the business. Letting this lapse can mean the corporation misses a lawsuit filing and faces a default judgment.
- Corporations are expected to hold annual shareholder meetings and regular board meetings and to keep written minutes of the decisions made.
- The corporation must maintain its own bank accounts. Corporate funds should never be mixed with personal money.
A corporation that fails to file required reports or maintain a registered agent risks administrative dissolution. Once dissolved, the entity can no longer conduct business, and officers or directors who keep operating it can face personal liability for debts incurred afterward. Most states allow reinstatement, but the process involves filing overdue reports and paying back fees and penalties.
The liability shield that makes corporations attractive is not bulletproof. Courts can pierce the corporate veil and hold shareholders personally responsible for corporate debts when the entity has been misused. The factors courts weigh include mixing personal and corporate funds, ignoring corporate formalities such as meetings and minutes, starting the business with far too little capital relative to its foreseeable risks, letting a single individual dominate the entity so completely that it has no independent existence, and using the corporation to commit fraud or evade an existing legal obligation. Commingling funds is the red flag that comes up in nearly every successful veil-piercing case, because it directly contradicts the premise that the corporation is separate from its owners.
How a Corporation Differs From an LLC
Limited liability companies share the corporation’s most appealing feature: owners are shielded from personal liability for business debts. The two structures differ in ways that matter depending on the business’s goals.
Corporations have a rigid governance structure. They must adopt bylaws, issue stock, hold annual meetings, and keep formal minutes. LLCs are more flexible. They are governed by an operating agreement the members can draft to suit their needs, and most states impose fewer recordkeeping requirements. That flexibility makes LLCs popular with small businesses, while the formality of a corporation suits companies that need outside investment or plan to go public.
Ownership transfer is another key difference. Corporate stock is freely transferable so long as any applicable restrictions, such as S-corporation shareholder limits, are met. LLC membership interests usually require approval from other members before they can be transferred, which makes it harder to bring in new investors or exit quickly. Corporations can also issue multiple classes of stock with different rights, giving them tools for complex capital-raising that LLCs lack.
On taxes, a standard C-corporation faces double taxation, while an LLC is taxed as a pass-through by default, with profits flowing to the owners’ personal returns. An LLC can elect to be taxed as an S-corporation or even a C-corporation if its owners prefer. The trade-off is that investors, venture capital firms, and public markets overwhelmingly prefer the corporate form, so businesses with ambitions beyond a small ownership group almost always choose to incorporate.
