How to Form a C Corporation: Filing, Bylaws, and Stock Issuance

To form a C corporation, you file articles of incorporation with your state, adopt bylaws, hold an organizational board meeting, issue stock to the initial shareholders, and obtain a federal Employer Identification Number from the IRS. State filing fees run from roughly $35 to $800, and if you file online the corporation can legally exist within a few business days. Once formed, it is a separate legal entity that owns property, signs contracts, sues and is sued in its own name, and pays its own federal income tax at a flat 21 percent rate.¹

Choose and Clear a Corporate Name

Your corporation’s name must be distinguishable from every other name already on file with the state’s business registry. Almost every secretary of state runs a free preliminary name search on its website, so check availability before you spend time on anything else. If the name you want is taken, you either pick something new or change it enough to be distinguishable under state rules. Many states will let you reserve an available name for 60 to 120 days while you finish your paperwork.²

The name generally has to end with a designator like “Corporation,” “Incorporated,” “Limited,” or an abbreviation of one of those. That signals limited liability to anyone doing business with you. States each maintain their own list of restricted words, so read the specific rules on your secretary of state’s site.

Appoint a Registered Agent

Every state requires the corporation to have a registered agent: a person or company designated to accept lawsuits and official government notices for the business. The agent needs a physical street address in the state of incorporation and has to be available during normal business hours. A P.O. box does not qualify.

You can serve as your own agent, use another individual who lives in the state, or hire a commercial registered agent service (typically $100 to $300 per year). The main reason people pay for a service is reliability. A missed service of process can produce a default judgment against the company. Whoever you name, that person’s name and address go into the articles of incorporation and onto the public record.

File the Articles of Incorporation

The articles of incorporation, sometimes called the certificate of incorporation or corporate charter, are the document that legally creates the corporation. You file them with the secretary of state or equivalent agency, usually through an online portal. Most states ask for the same short list of details:

The corporate name, including its required designator.
The registered agent’s name and physical address.
The incorporator, meaning the person filing the document, who need not be a future shareholder or director.
The number of authorized shares, and their par value if applicable.
A statement of business purpose; most states accept something as broad as “any lawful business activity.”

Par value is the minimum price a share can be sold for. Modern incorporations often set par value at $0.001 or $0.00, because a higher par value can push up franchise taxes in some states. A few states have eliminated par value entirely.

Online filings are commonly processed in a few business days, sometimes within 24 hours; paper filings can take weeks. Filing fees range from about $35 in the cheapest states to $800 at the top end, with most between $50 and $300. Some states also collect a franchise tax or initial report fee at filing. Keep the certificate of incorporation, or the date-stamped copy the state returns, in your permanent records. Your bank and the IRS will ask to see it.

Adopt Corporate Bylaws

Bylaws are the internal rules that govern how the corporation makes decisions. They are not filed with the state. They live in your corporate records and can be amended by the board or shareholders later. At a minimum, bylaws should cover:

The board of directors: how many serve, how they are elected, term length, and how vacancies are filled.
Meetings: how often the board and shareholders meet, what makes a quorum, and whether meetings can happen by phone or video.
Officers: which positions exist (President, Secretary, Treasurer) and what each is authorized to do.
Voting thresholds for major decisions such as amending the bylaws, approving a merger, or removing a director.
Any restrictions on how shareholders can transfer their shares.

Vague voting rules or unclear officer authority can freeze a company during a dispute. If there are co-founders or outside investors, spend real time on what happens when the board is deadlocked.

Hold the Organizational Board Meeting

The first board meeting formalizes what you have built on paper. The board typically adopts the bylaws, appoints officers, authorizes the corporation to open a bank account, approves the issuance of the initial shares, and picks a fiscal year. If you plan to elect S corporation status, the board should authorize filing Form 2553 at this meeting as well.

Take written minutes of every decision and have the Secretary sign them. Courts look at whether the corporation actually operates as a separate entity when deciding whether to pierce the corporate veil and reach the shareholders personally. Consistent minutes are among the strongest pieces of evidence that the entity is real. Store the signed minutes in the corporate record book alongside the articles and bylaws.

The organizational meeting is also a natural moment to adopt a conflict of interest policy. It does not have to be elaborate: define what counts as a conflict, require directors and officers to disclose any personal interest in a transaction, and set out how the board handles it, usually by having the conflicted person recuse themselves from the vote.

Issue Stock and Open a Stock Ledger

Issuing shares creates the ownership link between the corporation and its shareholders. The board authorizes the issuance at the organizational meeting, and the corporation then delivers stock certificates, physical or electronic, in exchange for each shareholder’s contribution of cash, property, or services (whatever the articles and board resolution allow).

Total shares issued can never exceed the number authorized in the articles. To go higher, you have to amend the articles and pay the associated fee.

Keep a stock ledger that records every issuance, transfer, and cancellation. A useful entry includes the certificate number, shareholder name, number of shares, date, and whether the transaction is an original issuance or a transfer. This is your definitive record of who owns the company, and sloppy entries here cause serious problems during an acquisition, audit, or shareholder fight.

Section 1244 Stock

If the corporation qualifies as a “small business corporation” when it issues stock, meaning the total capital received for all stock issued does not exceed $1 million, shareholders may be able to treat losses on that stock as ordinary losses rather than capital losses. Ordinary losses offset regular income dollar for dollar, while capital losses are capped at $3,000 per year against ordinary income. The ordinary loss limit under Section 1244 is $50,000 per individual, or $100,000 on a joint return.³

To qualify, the stock must be issued directly to an individual (or a partnership) for money or property, not for other stock or securities. The corporation must also draw more than half of its gross receipts from active business operations rather than passive sources like rent, royalties, or investment income during the five years before the loss. No special election is required; you just have to meet the criteria and keep records that prove it.³

Get an Employer Identification Number

An EIN is the nine-digit tax ID the IRS assigns to your corporation. You need one to file tax returns, hire employees, and open a business bank account. Every corporation must have one, employees or not.⁴

The fastest route is the IRS online application, which issues the number the moment it approves you. The online tool runs Monday through Friday from 6:00 a.m. to 1:00 a.m. Eastern, Saturdays until 9:00 p.m., and Sundays from 6:00 p.m. to midnight. You have to complete it in one session; it times out after 15 minutes of inactivity. Expect to give the corporation’s legal name, address, formation date, and the name of a “responsible party,” typically a principal officer or director.⁵

You can also mail or fax Form SS-4, but those channels take days to weeks.⁶

Handle Securities Compliance for the Stock You Issue

Issuing stock is a securities transaction, and federal law requires either SEC registration or an exemption. For most new corporations selling shares to founders and a small group of investors, Rule 506(b) of Regulation D is the go-to exemption.⁷

Under Rule 506(b), you can raise an unlimited amount from an unlimited number of accredited investors, plus up to 35 non-accredited investors who are financially sophisticated enough to evaluate the deal. You cannot use general advertising or solicitation to find buyers, and any non-accredited investors must receive detailed disclosure documents similar to what a registered offering would provide.⁷

After the first sale, you must file a Form D notice with the SEC within 15 days.⁸ Most states require their own “blue sky” notice filing, generally a copy of the Form D and a fee. Check your state securities regulator for what applies.

Understand How the C Corp Will Be Taxed

The defining tax feature of a C corporation is double taxation. The corporation pays federal income tax on its profits at 21 percent.¹ When after-tax profits go out as dividends, shareholders pay tax again on their personal returns. Qualified dividends are taxed at 0, 15, or 20 percent depending on the shareholder’s bracket, but the combined tax load is still typically higher than a pass-through entity pays on the same income.

C corps carry advantages that can outweigh that cost: no cap on the number or type of shareholders, the ability to issue multiple classes of stock (something venture investors usually require), and deductibility of certain fringe benefits. If you plan to raise institutional capital or eventually go public, the C corporation is often the only workable structure.

Electing S Corporation Status Instead

If the double layer doesn’t fit your situation, you can elect S corporation tax treatment by filing Form 2553 with the IRS. Income then passes through to shareholders’ individual returns, and the corporate-level tax disappears. To qualify, the corporation can have no more than 100 shareholders and only one class of stock, and all shareholders must be U.S. citizens or residents (with limited exceptions for certain trusts and estates).

The election must be filed no later than two months and 15 days after the beginning of the tax year in which it is to take effect. For a newly formed corporation, that means within 75 days of the incorporation date if you want the election to cover the first year. Miss it and the corporation is taxed as a C corp for the entire first year.

Keep the Corporation in Good Standing

Nearly every state requires corporations to file a periodic report, annually or biennially, updating the corporation’s address, officers, directors, and registered agent. Fees typically run from $10 to a few hundred dollars. Miss the deadline and you face late fees and, eventually, administrative dissolution.

A dissolved corporation loses the right to do business. It cannot bring lawsuits, its transactions may be void, and people acting on its behalf during the dissolution can be personally liable for debts incurred in that window. Most states allow reinstatement once you file the overdue reports and pay back fees, but any gap in legal protection can be expensive if a problem surfaces during it.

Many states also impose a franchise tax, calculated in different ways: flat fee, authorized shares, net worth, or gross receipts. If you authorized a large number of shares, check whether your state’s franchise tax scales with share count before the first bill lands.

Registering in Other States

Your corporation is “domestic” only in the state where you filed the articles. If you do business in other states, meaning you have employees, offices, or significant sales activity there, you generally have to register as a “foreign” corporation in each of them. Foreign qualification means filing an application for a certificate of authority, paying a fee (generally $25 to $750), and appointing a registered agent in that state. Operating without qualifying can bring fines, inability to enforce contracts in that state’s courts, and back taxes.

Beneficial Ownership Information Reporting

The Corporate Transparency Act originally required most new corporations to file a Beneficial Ownership Information report with FinCEN. In March 2025, FinCEN issued an interim rule exempting all domestic companies from the requirement. As of early 2026, U.S.-formed corporations do not need to file BOI reports.⁹ FinCEN indicated it would finalize the rule, but the regulatory picture could shift. A foreign entity registering to do business in the U.S. is still subject to the 30-day BOI filing requirement.¹⁰
