To form a corporation, you choose a state, pick a corporate name, appoint a registered agent, and file articles of incorporation with that state’s Secretary of State along with the filing fee. Everything else — bylaws, an EIN, an organizational meeting, stock issuance, tax elections, and ongoing reports — happens either right after the state approves your filing or on a recurring schedule for the life of the company. The steps below walk through how to form a corporation from the decisions you make before filing to the compliance work that keeps the entity in good standing.
What You Decide Before Filing
A handful of choices need to be settled before you touch a form, because they go directly onto the articles of incorporation and are harder to change later.
Corporate Name
Your name must be distinguishable from every other entity already registered in the state where you’re incorporating. Most states require a corporate designator in the name itself, such as “Corporation,” “Incorporated,” “Corp.,” or “Inc.,” so anyone dealing with the company knows what it is. Your state’s business registry usually has an online search tool for checking availability before you commit.
Registered Agent
Every corporation needs a registered agent with a physical street address in the state of incorporation. The agent accepts legal documents on the company’s behalf, including lawsuits and government notices, and must be available during normal business hours. That availability requirement is why many businesses hire a professional registered agent service rather than assigning the role to an owner who might not always be at a desk.
Authorized Shares
The articles have to state the maximum number of shares the corporation can issue. You don’t have to issue all of them right away, but the ceiling is set at filing. Authorize too few and you’ll pay another filing fee to amend the articles when you bring in investors. Authorize too many and some states will charge you more, because they base fees on share count. A common starting point for small corporations is somewhere between 1,000 and 10,000 shares, but the right number depends on your capitalization plans.
You can also authorize more than one class of stock. Common stock carries voting rights and represents baseline ownership. Preferred stock typically gives up voting rights in exchange for priority when dividends are paid and if the company liquidates. Many startups issue preferred shares to investors while founders hold common stock.
Filing the Articles of Incorporation
The articles of incorporation are the document that legally creates the corporation. Most states provide a standardized form, and the required information is fairly consistent: the corporate name, the registered agent’s name and address, the business purpose, and the number of authorized shares.
You file with the Secretary of State (or equivalent agency) in the state you’ve chosen. Most states offer online filing with near-instant processing; paper filing by mail is still available. Administrative fees vary widely, generally ranging from around $50 to several hundred dollars, with a few states charging more, especially those that calculate fees based on authorized share count or par value. Expedited processing is usually available for an extra charge.
Once the state approves the filing, you receive a certificate of incorporation or a stamped copy of your articles. That document is the corporation’s birth certificate. You’ll need it to open bank accounts, apply for licenses, and enter contracts.
Doing Business in Other States
If the corporation plans to operate in states beyond where it was formed, it generally needs to register as a “foreign corporation” in each of those states. That means filing an application for authority (sometimes called a certificate of authority), paying an additional fee, and appointing a registered agent in that state. Operating in another state without registering can result in fines and may bar the corporation from enforcing contracts in that state’s courts.
Writing the Bylaws
Bylaws are the corporation’s internal rulebook. They spell out how meetings are called, how votes work, what powers officers have, and how the board operates. Bylaws are not filed with the state. They stay in the corporate records and can be amended by the board or shareholders as the business evolves.
Treating bylaws as an afterthought is a common early mistake. Poorly drafted bylaws create confusion during disputes, which is exactly when you need clear rules.
What to Do Right After the State Approves You
The certificate of incorporation gets the entity into existence. Several tasks need to happen right away before the corporation starts doing business.
Get an Employer Identification Number
The corporation needs an Employer Identification Number from the IRS. This nine-digit number identifies the business for tax filings, and you’ll need it to open a corporate bank account or hire employees. Applying online through the IRS website is free and produces the EIN immediately.1Internal Revenue Service. Get an Employer Identification Number The IRS never charges a fee for an EIN, so be cautious of third-party websites that do.
Hold the Organizational Meeting
The initial board of directors (or the incorporators, if no directors are named in the articles) holds an organizational meeting. During this meeting, the board formally adopts the bylaws, authorizes the issuance of stock to the initial shareholders, elects officers, and ratifies any actions taken during the formation process. Every decision should be recorded in written minutes and kept in a corporate minute book.
Sloppy or nonexistent records are one of the fastest ways to lose liability protection later.
Handle Securities Compliance When Issuing Stock
This is where new corporations most often stumble. Every sale of stock, even to your co-founder sitting across the kitchen table, must either be registered with the SEC or qualify for an exemption from registration.2U.S. Securities and Exchange Commission. Exempt Offerings Full registration is expensive and complex, so most small corporations rely on an exemption.
The most commonly used exemptions include:
- Rule 506(b), which allows unlimited fundraising from accredited investors and up to 35 non-accredited investors but prohibits general advertising of the offering.3U.S. Securities and Exchange Commission. Private Placements – Rule 506(b)
- Rule 506(c), which permits general solicitation but requires all purchasers to be verified accredited investors.
- Rule 504, which covers offerings up to $10 million in a 12-month period.
- Regulation Crowdfunding, which allows offerings up to $5 million through a registered online platform.
A company relying on Rule 506 must file a Form D with the SEC within 15 days of the first sale.3U.S. Securities and Exchange Commission. Private Placements – Rule 506(b) States can also require their own notice filings and fees. Investors who purchased stock in an unregistered, non-exempt offering may have the right to demand their money back, which can unravel a company’s entire capitalization.
Choosing How the Corporation Is Taxed
Every corporation starts as a C-corp for federal tax purposes. Whether to keep that default or elect S-corp status is one of the most consequential decisions after incorporating.
C-Corporation Taxation
A C-corp pays federal income tax at a flat rate of 21% on its taxable income.4Office of the Law Revision Counsel. 26 USC 11 – Tax Imposed When the corporation distributes profits to shareholders as dividends, shareholders pay tax again on that income at their individual rates. This is the “double taxation” the C-corp structure is known for.
Salaries paid to shareholder-employees are deductible business expenses, so money paid as compensation is taxed only once. The corporation can also retain earnings rather than distributing them, deferring the second layer of tax until dividends are eventually paid or shareholders sell their stock. Interest payments on loans are tax-deductible; dividend payments are not.
Electing S-Corporation Status
An S-corp passes profits and losses through to shareholders, who report them on their personal tax returns. The corporation itself generally owes no federal income tax.
To elect S-corp status, the corporation files Form 2553 with the IRS, and every shareholder must consent to the election.5Office of the Law Revision Counsel. 26 USC 1362 – Election; Revocation; Termination The deadline is no later than two months and 15 days into the tax year for the election to apply to that year. File after that window and it takes effect the following year.
Not every corporation qualifies. The requirements are specific:6Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined
- The company must be a domestic corporation organized in the United States.
- It can have no more than 100 shareholders; spouses count as one, and all members of one family can be treated as one shareholder.
- Shareholders must be individuals, certain trusts, or estates. Other corporations, partnerships, and most non-U.S. residents cannot hold shares.
- The corporation can have only one class of stock. All shares must carry identical rights to distributions and liquidation proceeds; differences in voting rights alone are permitted.
- Banks using the reserve method for bad debts, insurance companies taxed under subchapter L, and DISCs or former DISCs cannot elect S-corp status.
Through 2025, S-corp shareholders could deduct up to 20% of their qualified business income under Section 199A, which significantly reduced the effective tax rate on pass-through income.7Internal Revenue Service. Qualified Business Income Deduction That deduction expired at the end of 2025 for tax years beginning in 2026. If Congress has not extended it by the time you file, S-corp income will be taxed at ordinary individual rates without that 20% cushion. Check current IRS guidance before locking in the decision.
Governance the Law Requires
Corporate governance follows a three-tier hierarchy. This structure is not optional. State corporation statutes require it, and failing to maintain it can undermine the liability protections the corporate form provides.
Shareholders own the corporation but don’t run its daily operations. Their main powers are electing and removing board members, voting on major structural changes like mergers or dissolution, and approving amendments to the articles of incorporation. They exercise these powers at annual meetings and, when urgent matters arise, at special meetings called under procedures in the bylaws.
The board of directors sets strategic direction. Directors authorize major transactions, declare dividends, approve the issuance of additional shares, and hire the officers who handle daily management. Directors owe fiduciary duties to the corporation and its shareholders, including a duty of care (making informed decisions) and a duty of loyalty (putting the corporation’s interests ahead of their own). When a conflict of interest arises, the director must disclose it and step back from the vote.
Officers execute the board’s decisions. Typical titles include Chief Executive Officer, Secretary, and Treasurer, though a small corporation can assign multiple roles to the same person. Officers manage employees, sign contracts, handle finances, and answer to the board.
Keeping the Liability Shield Intact
Limited liability is the main reason most people incorporate, and the protection is not automatic. Courts can “pierce the corporate veil” and hold shareholders personally responsible for the corporation’s debts if the company is being used as a personal alter ego rather than a genuine separate entity. When that happens, creditors can reach personal assets like homes and savings accounts.
Courts look at several factors. No single failure is usually fatal, but they pile up fast:
- Commingling funds. Paying personal expenses from the corporate account, or running business charges through a personal credit card, is the biggest red flag.
- Undercapitalization. Forming a corporation without putting enough money in to cover reasonably foreseeable obligations suggests the entity was set up to shift risk rather than to operate a real business.
- Ignoring corporate formalities. Skipping board meetings, failing to keep minutes, never issuing stock certificates, and operating without bylaws all tell a court that the owners don’t take the corporation’s separate existence seriously.
- Lack of separation. Using corporate assets for personal errands, failing to sign contracts in the corporation’s name, and not maintaining separate letterhead and business cards blur the line between the entity and the individual.
Keep a dedicated corporate bank account and never run personal expenses through it. Hold and document annual meetings even if you’re the sole shareholder. Maintain your corporate minute book. Sign contracts as an officer of the corporation, not in your personal capacity. These habits feel like busywork when things are going well, and they become the entire ballgame when a creditor comes after you personally.
Annual Reports and Franchise Taxes
Incorporating is a one-time event. Staying in compliance is permanent. Most states require corporations to file an annual or biennial report with updated information about the company’s officers, directors, registered agent, and principal address. The filing fee varies by state, and some states impose additional franchise taxes or minimum entity taxes that apply regardless of whether the corporation earned any profit that year. These obligations begin the year after formation and continue until the corporation formally dissolves or withdraws from a state.
Missing an annual report deadline triggers late fees and can cause the corporation to fall out of good standing. Lose good standing status and the state may refuse to issue compliance certificates, which lenders and contracting partners routinely require. Continued noncompliance can result in the state administratively dissolving the corporation entirely, stripping its liability protections and its authority to do business. Even if you stop operating in a state where you previously registered as a foreign corporation, the filing obligation continues until you formally withdraw.
