A corporation is a business that the law treats as its own person, legally separate from the people who own it. It can own property, sign contracts, borrow money, sue, and be sued in its own name. That separateness is the whole point: the corporation’s debts and legal problems belong to the corporation, not to you. The U.S. Supreme Court described the idea in 1819 as “an artificial being, invisible, intangible, and existing only in contemplation of law.”1Legal Information Institute. Trustees of Dartmouth College v Woodward
A Separate Legal Person
When you form a corporation, you bring a new legal entity into existence. It has its own tax identification number, its own bank accounts, and its own obligations. If the corporation borrows money, the corporation owes the debt. If someone sues the business, the lawsuit names the corporation as the defendant, not the owners.
This separateness also gives a corporation something a sole proprietorship or partnership cannot have: perpetual existence. The Dartmouth College opinion pointed to “immortality” and “individuality” as among a corporation’s most important properties, allowing “a perpetual succession of many persons” to “act as a single individual.”1Legal Information Institute. Trustees of Dartmouth College v Woodward A shareholder can die, retire, or sell out, and the corporation keeps operating. It ends only when its owners formally shut it down or a court orders dissolution.
Who Owns a Corporation
Ownership is divided into units called shares of stock. Buy shares and you become a shareholder, with the right to vote on major decisions like electing directors and approving mergers. Voting power is normally proportional to how many shares you hold.
Corporations can issue different classes of stock with different rights. The two most common are common and preferred. Common shareholders vote and may receive dividends, but if the company is liquidated they get paid last, after creditors and preferred shareholders. Preferred shareholders get priority on dividends and on assets in a wind-down, but usually give up voting rights in exchange.
Shares are also what make ownership transferable. A sole proprietorship has no clean way to sell a slice of the business. A corporation does: you sell your shares, and the corporation itself continues operating regardless of who now holds the stock.
Who Runs a Corporation
Corporations are managed through a two-tier system. Shareholders elect a board of directors. The board sets strategy, approves budgets, and hires the officers—CEO, CFO, and others—who run day-to-day operations.
Directors owe two core duties. The duty of care requires informed, thoughtful decisions, measured against what a reasonably careful person would do in the same role. The duty of loyalty requires directors to put the corporation’s interests ahead of their own, disclose conflicts of interest, and step aside from decisions where they have a personal financial stake. A director who breaches either duty can be personally liable for the harm.
Most states allow one person to be the sole director, sole officer, and sole shareholder. You don’t need a large team to have a corporation.
Limited Liability, and How It Can Be Lost
Limited liability is the reason most people incorporate in the first place. Because the corporation is its own legal person, its debts belong to the entity. If the business fails owing creditors $500,000, those creditors can go after the corporation’s assets, but your house, savings, and personal property are off the table. The most you can lose is what you paid for your shares.2U.S. Small Business Administration. Choose a Business Structure
Compare that to a sole proprietorship, where there’s no legal separation. Your business debts are your personal debts, and a creditor can come after everything you own.2U.S. Small Business Administration. Choose a Business Structure
The shield isn’t bulletproof. Courts can “pierce the corporate veil” and hold shareholders personally responsible when the corporate structure has been abused. The most common trigger is commingling funds: using the corporation’s bank account for personal expenses, or running business income through a personal account. When your money and the corporation’s money flow through the same channels, a court may decide there was never any real separation to protect.
Other factors that put the veil at risk include starting the business with far too little capital relative to its debts, skipping board meetings and corporate records, and running the corporation as a shell with no real purpose except to shield its owner. No single factor decides the question; courts look at the whole picture, and the party trying to pierce the veil carries the burden of proof. The practical lesson is simple. Treat the corporation as a real, separate entity. Keep its money separate. Hold your meetings. Document your decisions. Make sure it has enough resources to cover its foreseeable obligations.
How Corporations Are Taxed
C Corporation and Double Taxation
By default, a corporation is taxed as a C corporation. The federal corporate income tax is a flat 21% on taxable income.3Office of the Law Revision Counsel. 26 USC 11 – Tax Imposed Most states add a corporate tax on top.
The tradeoff is double taxation. The corporation pays income tax on its profits first. Then, if it distributes any of those after-tax profits to shareholders as dividends, the shareholders pay tax again on their individual returns. Qualified dividends are taxed at a capital gains rate of up to 20%, and higher earners may owe an additional 3.8% net investment income tax. The combined bite is real, which is why smaller corporations often try to minimize distributions or avoid C corporation status altogether.
S Corporation Election
To sidestep double taxation, eligible corporations can elect S corporation status by filing Form 2553 with the IRS. An S corporation pays no federal income tax at the corporate level. Profits and losses flow through to the shareholders’ personal returns and are taxed once at individual rates.4Internal Revenue Service. S Corporations
Not every corporation qualifies. The business must be a domestic corporation with no more than 100 shareholders, and all shareholders must be individuals, certain trusts, or estates, not other corporations or partnerships. Nonresident aliens cannot be shareholders, and the corporation can have only one class of stock.5Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined S status fits smaller, closely held businesses; it isn’t available to larger companies with complex ownership.
Public vs. Private Corporations
A private corporation’s shares are held by a limited group of founders, employees, and early investors, and can’t be bought by the general public. A public corporation has issued shares to the public through an initial public offering and trades on an exchange like the NYSE or Nasdaq.
The main practical difference is regulatory weight. Public corporations must file annual reports (Form 10-K), quarterly reports (Form 10-Q), and current reports (Form 8-K) with the Securities and Exchange Commission, with the CEO and CFO personally certifying the financial information. All of it becomes publicly available through the SEC’s EDGAR system.6U.S. Securities and Exchange Commission. Exchange Act Reporting and Registration Private corporations don’t publish financial statements and don’t report ownership changes to a federal agency. What they give up is access to capital: a public company can raise enormous sums from millions of investors; a private company negotiates directly with individuals, venture capital firms, or private equity funds.
How a Corporation Compares to an LLC and Other Structures
Whether a corporation is the right choice depends on how much liability protection you need, how you want to be taxed, and how much administrative overhead you’re willing to carry.
- Sole proprietorship. The simplest structure. No formation paperwork, no separate entity, no liability protection. You and the business are legally the same person, and income is reported on your personal tax return.2U.S. Small Business Administration. Choose a Business Structure
- Partnership. Two or more owners. General partners have unlimited personal liability. Limited partnerships give some protection to silent investors, and limited liability partnerships shield each partner from the others’ actions. Income passes through to the partners’ individual returns.2U.S. Small Business Administration. Choose a Business Structure
- LLC. A hybrid that combines a corporation’s liability protection with a partnership’s tax flexibility. Members are generally shielded from business debts, and income passes through to individual returns by default. LLCs have fewer ongoing formalities: no mandatory board meetings, no required officer titles, less paperwork. For small businesses that don’t plan to seek outside investors or go public, an LLC is often more practical.
- Corporation. The most formal structure. The strongest liability protection and the clearest path to raising capital by issuing stock, at the cost of mandatory governance requirements, higher formation costs, and, for C corporations, double taxation.2U.S. Small Business Administration. Choose a Business Structure
A corporation makes the most sense when a business expects to raise money from outside investors, plans to go public, or wants the credibility and structure of a formal corporate framework. When none of those apply, a simpler structure often saves time and money without giving up much of the protection that matters.
