To form a corporation as a U.S. citizen, you file articles of incorporation with a state, appoint a registered agent, name directors, adopt bylaws, and obtain an Employer Identification Number from the IRS. The corporation is a separate legal entity from you. You don’t become the corporation; you create it and then hold roles in it as shareholder, director, or officer.
The Roles You Hold in Your Own Corporation
A corporation is its own legal person. It owns property, signs contracts, pays taxes, and can sue or be sued in its own name. You interact with it through defined roles:
- Incorporator, the person who signs and files the formation documents. The role ends once the corporation exists.
- Shareholder, an owner of stock who votes to elect directors and weighs in on major decisions like mergers or dissolution.1Investor.gov. Shareholder Voting
- Director, a board member who oversees strategy and appoints officers.
- Officer, the CEO, CFO, secretary, or other executive who runs daily operations.
In a small corporation, one person often fills every role. You can be the sole shareholder, the only director, and the CEO at the same time. Every state allows this. The catch is that wearing all the hats makes it easier to blur the line between you and the corporation, which is exactly what you need to avoid if you want the liability protection to hold.
The Filing Steps
Incorporation happens at the state level. You pick one state to form in, even if you operate in several. The state you choose supplies the corporate law that governs your entity, which is why Delaware and Nevada draw many filings from businesses that operate elsewhere.
Choose and Reserve a Name
Your corporate name must be distinguishable from other entities already on file with the state’s filing office, usually the Secretary of State. Most states let you reserve a name for a short period while you prepare the rest of your paperwork.
Appoint a Registered Agent
Every corporation needs a registered agent in its state of incorporation. The agent is the person or service that accepts legal papers and official correspondence for the corporation. You can act as your own agent in many states, or hire a commercial service.2U.S. Small Business Administration. Register Your Business
File Articles of Incorporation
Articles of incorporation (sometimes called a certificate of incorporation) are the core formation document. They typically include the corporate name, registered agent information, the corporation’s stated purpose, and the number of shares the corporation is authorized to issue. State filing fees generally run from about $75 to $300, with a handful of states charging more.
Adopt Bylaws and Hold an Organizational Meeting
Once the state approves your filing, the incorporator or initial directors hold an organizational meeting to adopt bylaws (the internal operating rules), elect directors, appoint officers, and authorize the issuance of stock. Keep minutes. These documents are what you point to later if anyone questions whether the corporation is a real, functioning entity.
Get an EIN
Apply to the IRS for an Employer Identification Number. You need it to open a business bank account, hire employees, and file corporate tax returns. The IRS issues EINs online at no charge.3Internal Revenue Service. Get an Employer Identification Number
Local Licenses and Permits
Beyond the state filing, your city or county may require a general business license, and specific industries have their own permit requirements. Check with the local clerk’s office before you begin transacting business.
Pick Your Tax Treatment: C-Corp or S-Corp
Every corporation begins as a C corporation by default. The federal corporate tax rate is a flat 21% on taxable income.4GovInfo. 26 USC 11 – Tax Imposed After the corporation pays that tax, dividends paid out to shareholders are taxed again on the shareholders’ personal returns. That is the “double taxation” people associate with C corps.5Internal Revenue Service. Forming a Corporation
S-corporation status eliminates the corporate-level tax. Profits and losses pass through to shareholders’ personal returns, similar to a partnership. To elect S-corp treatment, file IRS Form 2553 within two months and 15 days of the start of the tax year you want the election to take effect, or within the same window after formation for a new corporation.
S-Corp Eligibility
S corporations are capped at 100 shareholders, all of whom must be U.S. citizens or resident aliens. Partnerships, other corporations, and nonresident aliens cannot hold shares. Certain trusts and tax-exempt organizations qualify under narrow rules.6Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined An S corporation can also have only a single class of stock.7Internal Revenue Service. S Corporations C corporations have no such restrictions and can take foreign investors, multiple stock classes, and corporate shareholders.
One tax trap worth knowing before you elect S status: if you work in the business, the corporation must pay you a reasonable salary before you take distributions. The IRS treats S-corp officers performing more than minor services as employees subject to employment taxes regardless of how the payments are labeled.8Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers Paying yourself $20,000 for a job the market pays $80,000 for is the kind of thing that invites an audit.
Keep Your Limited Liability Intact
Shareholders are generally not personally responsible for the corporation’s debts beyond what they invested. If the corporation is sued or goes bankrupt, creditors reach the corporation’s assets, not your home or savings. That protection has limits. Courts can “pierce the corporate veil” and hold you personally liable when you treat the corporation as an extension of yourself. In small, single-owner corporations, this happens more than owners expect.
The specific test varies by state, but the recurring red flags are consistent:
- Commingling funds, meaning paying personal bills from the corporate account or running business revenue through your personal account. This is the fastest way to lose liability protection.
- Undercapitalization, meaning starting the corporation with so little money that it could never realistically meet its obligations.
- Ignoring corporate formalities, such as never holding board meetings, failing to keep minutes, or not documenting major decisions.
- Using corporate assets for personal purposes, like charging personal vacations or home expenses to the corporation.
- Fraud, meaning using the corporate form specifically to deceive creditors or avoid legal obligations.
Not every factor has to be present. A court may pierce the veil on extreme commingling alone or on a combination of smaller lapses. The practical defenses are a separate bank account, documented decisions, and enough capital in the corporation to meet foreseeable obligations.
Staying in Good Standing After You File
Forming the corporation is the first filing, not the last.
Annual Reports and Franchise Taxes
Most states require corporations to file an annual or biennial report updating basic information: the corporate name, principal office address, registered agent, and names of directors and officers. Many states also impose a franchise tax or minimum annual fee for the privilege of existing as a corporation there. Amounts vary widely. Miss these filings and the state charges late fees, then knocks the corporation out of good standing, and eventually dissolves it administratively. An administratively dissolved corporation can’t file lawsuits, close mergers, or prove to a bank that it legally exists. Reinstatement is usually possible but costs back fees and penalties.
Federal Tax Filings
A C corporation files Form 1120 and pays tax at the corporate level. An S corporation files an informational Form 1120-S and issues each shareholder a Schedule K-1 showing their share of income, deductions, and credits. Either way, the corporation has filing obligations separate from your personal return.
Beneficial Ownership Reporting
One rule to be aware of so you don’t go looking for a filing that no longer applies to you: the Corporate Transparency Act originally required most domestic corporations to report beneficial owners to the Financial Crimes Enforcement Network. As of March 2025, FinCEN issued an interim final rule exempting all U.S.-formed entities and their U.S. beneficial owners from that requirement. Only foreign entities registered to do business in the United States must file beneficial ownership reports now.9FinCEN. Beneficial Ownership Information Reporting A domestic corporation formed by a U.S. citizen has no current BOI reporting obligation, though a future final rule could change that.
