How to Form a Corporation: A Step-by-Step Guide
Forming a corporation creates a separate legal entity owned by shareholders and managed by a board of directors. Corporations have more formal requirements than LLCs but offer advantages for businesses that plan to raise capital, issue stock to employees, or eventually go public. This guide covers the formation process, the difference between C-corps and S-corps, and the formalities every corporation must observe.

C-Corp vs. S-Corp: Choosing the Right Structure
Every corporation is created as a C-corp by default. The C-corp is a separate taxable entity — it pays federal income tax on its profits, and shareholders pay tax again on dividends (the "double tax"). An S-corp is a tax election, not a separate type of entity — it is created by filing IRS Form 2553, and the corporation's profits and losses pass through to shareholders' personal tax returns, avoiding the double tax.
S-corp limits: S-corps are limited to 100 shareholders, one class of stock, and U.S. citizens/residents only. They cannot be owned by corporations, LLCs, or partnerships. These limits make S-corps unsuitable for businesses that plan to raise venture capital or that want multiple classes of equity. Most VC-backed startups are C-corps for this reason.
Step-by-Step: How to Form a Corporation
- Choose a state of incorporation Most small businesses incorporate in their home state. Delaware is the most popular state for larger companies and VC-backed startups because of its well-developed corporate case law and Court of Chancery. Forming out-of-state requires foreign qualification in your home state.
- Choose a unique corporate name The name must be distinguishable from other entities on file with the state and must include a corporate designation ("Inc.", "Corp.", "Corporation", "Company"). Reserve the name with the state if you are not ready to file immediately.
- Appoint directors and officers Corporations require a board of directors (typically 1 to 5 for small businesses) and officers (president, secretary, treasurer — the same person can hold multiple roles). Directors are elected by shareholders; officers are appointed by the board.
- File articles of incorporation The articles of incorporation (sometimes called a charter) is the document that creates the corporation. Includes the corporate name, registered agent, principal office, authorized shares, and incorporator's name. Filing fees range from $50 to $300.
- Adopt bylaws Bylaws are the internal governance document for the corporation. They define the rights and responsibilities of directors, officers, and shareholders, and the rules for meetings and decisions. Required by every state.
- Hold an organizational meeting The board holds its first meeting to adopt bylaws, appoint officers, authorize share issuances, and approve initial corporate actions. Minutes must be kept.
- Obtain an EIN and open a bank account Required for tax filing, banking, and payroll. Free from the IRS, issued instantly.
- Issue stock and file an S-corp election if applicable Issue stock to the founders (often in exchange for cash or assets contributed to the corporation). If you want S-corp tax treatment, file IRS Form 2553 within 75 days of formation.
- Comply with ongoing formalities Corporations must hold annual shareholder meetings, elect directors, file annual reports, and maintain separate books and records. Failure to observe corporate formalities can pierce the corporate veil.
Corporation vs. LLC: When to Choose Each
- Choose a corporation when — you plan to raise venture capital, you want to issue stock options to employees, you plan to go public, or you want a well-established governance framework
- Choose an LLC when — you want pass-through taxation by default, fewer formalities, more flexible management structure, or a simpler ongoing compliance burden
- Both structures — provide limited liability protection, require separate bank accounts, require state filings, and offer similar asset protection benefits
- Tax note — both LLCs and corporations can elect to be taxed as the other; an LLC can elect corporate taxation, and a corporation (with limitations) can elect S-corp pass-through taxation
Frequently Asked Questions
Is forming a corporation worth the extra formalities?
It depends on your plans. For businesses that intend to raise venture capital, issue equity to employees, or eventually go public, a C-corp is essentially required (VCs require it; employee stock options are easier to grant; IPOs require it). For lifestyle businesses, consulting practices, real estate holdings, and most small businesses, an LLC is simpler and equally protective.
What is the difference between articles of incorporation and bylaws?
Articles of incorporation are filed with the state and create the corporation. They include basic information (name, registered agent, authorized shares). Bylaws are the internal governance document and are not filed with the state. They include detailed rules for directors, officers, meetings, and shareholder rights. Both are required; they serve different purposes.
Can a corporation have only one shareholder?
Yes. A corporation can have a single shareholder and a single director (in most states). Many small business owners form single-shareholder corporations for the formal structure. S-corp status is generally available to single-shareholder corporations as long as the other S-corp requirements (one class of stock, U.S. citizen, etc.) are met.
