Corporate law, explained in practical terms, is the body of state and federal rules that lets a business exist as a legal entity separate from its owners: it can sign contracts, hold property, sue and be sued, pay its own taxes, and continue after ownership changes. Every state has its own corporate statute, but most follow the Model Business Corporation Act or a close variation, so the core rules look similar across the country. What follows walks through the life of a corporation from the day it is formed to the day it is closed.
Forming a Corporation
A corporation comes into existence when articles of incorporation (also called a certificate of incorporation or corporate charter) are filed with the state’s filing office, usually the Secretary of State. The document is short, but every element carries legal weight.
The corporate name has to be distinguishable from other entities already registered in the state. Under the Model Business Corporation Act, the name must include a word like “Corporation,” “Incorporated,” “Company,” or “Limited,” or an abbreviation like “Corp.,” “Inc.,” “Co.,” or “Ltd.”1LexisNexis.

The articles must also name a registered agent with a physical address in the state of formation. That agent receives lawsuits, tax notices, and other official correspondence. If the company is ever sued and nobody accepts the papers, the case can go sideways quickly.
The articles state the number of shares the corporation is authorized to issue. If the company plans different classes of stock with different voting rights or dividend preferences, that structure has to be spelled out. A statement of corporate purpose is required, though most incorporators use broad, all-purpose language. Some states also require the names of the initial directors.
Filing Fees and Processing
Fees vary widely between states. Some charge under $100; others charge several hundred dollars, and a few add fees tied to the number of authorized shares. Processing runs from same-day approval on efficient online portals to several weeks where paper filings still dominate. Once approved, the state returns a stamped copy or certificate. That document is the corporation’s proof of existence and is needed to open a business bank account, apply for licenses, and establish credit in the company’s name.
Getting an EIN
Almost every corporation needs a Federal Employer Identification Number from the IRS. It functions as a tax identification number for the business. Applications are free on the IRS website and the number is issued immediately. You will need the entity type, the Social Security number of the responsible party, and basic identifying information.2Internal Revenue Service. Get an Employer Identification Number The IRS limits applications to one EIN per responsible party per day, and the online tool has session timeouts, so have your information ready before starting.
The Organizational Meeting and Bylaws
After the state accepts the filing, the corporation holds an organizational meeting. If the articles named initial directors, they call the meeting; if not, the incorporators meet first to elect directors. At this meeting, the board adopts bylaws, appoints officers, and authorizes the issuance of the first shares of stock.1LexisNexis. Model Business Corporation Act 3rd Edition Official Text
Bylaws are the corporation’s internal operating rules. They cover how meetings are called, how many directors serve, what officers the company will have, and how shares can be transferred. Bylaws are not filed with the state, but they carry real legal weight if disputes arise.
Securities Compliance When Issuing Stock
Issuing shares at the organizational meeting feels routine, but it triggers federal securities law. Every stock sale is technically a securities transaction, and unless an exemption applies it must be registered with the SEC. Most small corporations rely on private placement exemptions under Regulation D. Rule 506(b) lets a company raise an unlimited amount from accredited investors without general advertising, though sales to more than 35 non-accredited investors require additional disclosures. Form D must be filed with the SEC within 15 days of the first sale.3U.S. Securities and Exchange Commission. Private Placements – Rule 506(b) Skipping this step is one of the fastest ways to create legal exposure for a new company.
Who Runs a Corporation
A corporation operates through three layers of authority. Getting the boundaries right is what separates a well-run company from one that invites lawsuits.
Shareholders are the owners. They do not run the business day to day, but they hold powerful rights: electing and removing directors, approving major structural changes like mergers or amendments to the charter, and voting on dissolution.4Investor.gov. Shareholder Voting The default rule in most states is one vote per share, though companies can create shares with different voting power.
The board of directors sets strategic direction. Directors approve major transactions, declare dividends, and authorize the issuance of new stock. They do not handle daily operations; they hire officers and hold them accountable.
Officers run the business. The CEO, CFO, secretary, and other officers carry out the board’s directives, manage employees, and make operational decisions. Officers answer to the board, and the board answers to the shareholders.
What Directors and Officers Owe the Company
Directors and officers owe the corporation fiduciary duties, meaning they must put the company’s interests ahead of their own. Two duties do most of the work.
The duty of care requires directors to make informed decisions. Before approving a major transaction, the board needs to review the relevant materials, ask questions, and deliberate. In Smith v. Van Gorkom, the Delaware Supreme Court held directors personally liable because they approved a buyout based on a 20-minute presentation without reading the merger agreement or obtaining an independent valuation.5Justia. Smith v. Van Gorkom The case remains the standard reference for what an “informed decision” actually looks like.
The duty of loyalty prevents directors and officers from using their positions for personal gain. A director’s financial interest in a board transaction must be disclosed. Taking a business opportunity that belongs to the corporation, approving a deal that benefits you at the company’s expense, or competing with the company while serving on its board all violate this duty.
To keep boards from being paralyzed by second-guessing, courts apply the business judgment rule. Judges presume directors acted in good faith, with adequate information, and with an honest belief that the decision served the company. A shareholder challenging a board decision has to show fraud, self-dealing, or a failure to inform themselves before a court will look behind the decision itself.
When Shareholders Sue on the Company’s Behalf
When a shareholder believes the board itself has harmed the corporation, the shareholder can bring a derivative lawsuit on the company’s behalf. The injury runs to the corporation, not the individual shareholder. Before filing, the shareholder must formally demand that the board investigate the claim. If the board refuses, that refusal is reviewed under the business judgment rule. If the shareholder can show the board is too conflicted to evaluate the demand fairly, courts may excuse the demand requirement and let the lawsuit proceed.
How Corporations Are Taxed
One of the most consequential early decisions is how the corporation will be taxed. The default is C corporation status, but many smaller companies elect S corporation treatment.
C Corporation Taxation
A C corporation pays federal income tax on its profits at a flat rate of 21 percent.6Office of the Law Revision Counsel. 26 U.S. Code 11 – Tax Imposed When those after-tax profits are distributed as dividends, shareholders pay tax again at individual rates that can reach 23.8 percent when the net investment income tax applies. This two-layer structure is commonly called double taxation. In exchange, the C corporation offers flexibility: no limits on the number or type of shareholders, multiple classes of stock, and the ability to retain and reinvest earnings.
S Corporation Election
An S corporation avoids the entity-level tax. Profits and losses pass through to shareholders, who report them on their personal returns. To qualify, the corporation must have no more than 100 shareholders, all of whom must be U.S. citizens or resident aliens. Only one class of stock is permitted, though differences in voting rights alone do not create a second class.7Office of the Law Revision Counsel. 26 U.S. Code 1361 – S Corporation Defined Partnerships, other corporations, and nonresident aliens cannot hold shares.
To make the election, the corporation files IRS Form 2553 no later than two months and 15 days after the start of the tax year the election should take effect, or at any time during the prior tax year.8Internal Revenue Service. Instructions for Form 2553 Missing the window means waiting until the following year. It is a tight deadline that catches many new businesses off guard, especially those formed late in the calendar year.
Staying Compliant After Formation
Incorporation is not a one-time event. Maintaining corporate status requires ongoing filings and internal records, and falling behind has real consequences.
The corporation must keep minutes of all board and shareholder meetings. Minutes document who voted, what was approved, and why. If the corporation’s legal status is ever challenged, minutes are the first thing a court examines.
Most states require an annual or biennial report updating the state on the registered agent, principal office, and current officers or directors. Fees vary, but failing to file can cause the corporation to lose its good standing and eventually be administratively dissolved. Many states also charge annual franchise taxes simply for the privilege of existing as a corporation there. Failure to pay on time can cost the corporation the right to do business.
Shareholders are entitled to inspect certain corporate books and records when they have a legitimate reason tied to their ownership interest. This inspection right is a standard feature of corporate law, and the corporation cannot refuse a request that meets the legal requirements.
Shareholders must receive notice of annual meetings at least 10 to 60 days in advance. Bylaws usually specify the exact notice period within that range, and inadequate notice can invalidate actions taken at the meeting.
Keeping Your Limited Liability Protection
The point of incorporating is separating personal assets from company debts. That protection is not automatic, and it is not permanent. Courts can pierce the corporate veil and hold shareholders personally liable if the corporation is really just an alter ego of its owners.
The most common factor is commingling of funds. Paying personal expenses from the corporate bank account, depositing personal income into it, or treating the company’s money as your own blurs the line between owner and entity. When that line disappears, so does liability protection. A separate business bank account, with every business transaction running through it, is the bare minimum.
Other factors that invite veil-piercing include failing to hold required meetings, not keeping corporate minutes, undercapitalizing the company, and not maintaining the corporation as a distinct legal identity in dealings with third parties. None of these alone is usually enough, but courts look at the totality. The pattern that gets people in trouble is treating the corporation as a formality on paper while ignoring it in practice.
The protective habits are cheap. Hold annual meetings even when they feel pointless, record minutes, keep personal and business finances fully separate, and make sure the company has enough capital to cover foreseeable obligations.
Closing a Corporation
Ending a corporation’s existence is a formal, multi-step process. Skipping steps can leave shareholders exposed to lingering debts and tax liabilities years after they thought the business was closed.
State Dissolution
Voluntary dissolution starts with the board adopting a resolution recommending dissolution. That resolution goes to the shareholders for a vote, and most states require approval by a majority of outstanding shares. Once approved, the corporation files articles of dissolution with the Secretary of State.
Filing triggers the winding-up phase. During this period, the corporation must notify all known creditors and give them a reasonable window to submit claims. Under the Model Business Corporation Act framework most states follow, that window is at least 120 days from the date of the written notice. The corporation must settle all outstanding debts, including tax obligations, before distributing any remaining assets to shareholders. Distributions follow ownership percentages unless the articles or a shareholder agreement provide otherwise.
Federal Tax Filings at Dissolution
Closing with the state is not enough. The corporation must file IRS Form 966 within 30 days after the board adopts the plan of dissolution or liquidation.9Internal Revenue Service. Form 966 – Corporate Dissolution or Liquidation A final income tax return (Form 1120 for C corporations or Form 1120-S for S corporations) must be filed for the year the company closes, with the “final return” box checked near the top.10Internal Revenue Service. Closing a Business Capital gains and losses from selling off assets during winding up are reported on that return. Forgetting these federal obligations is how dissolved companies end up with IRS notices arriving at addresses where nobody is left to open them.
