To incorporate a business, you file a document called articles of incorporation with the Secretary of State in the state where you want the corporation formed, pay the filing fee, and then handle the internal setup that makes the entity actually functional: bylaws, an organizational meeting, stock issuance, and a federal tax ID. Learning how to incorporate a business is mostly a matter of doing these steps in the right order and keeping the paperwork clean afterward, because a corporation that isn’t maintained can lose the liability protection that made incorporating worthwhile in the first place.
Here is what each step actually involves.
Pick a Name the State Will Accept
Your corporate name has to be distinguishable from every other entity already on file with the Secretary of State. Nearly every state runs a free online business name database, so search it before you get attached to a name. If the name is available and you’re not ready to file yet, most states let you reserve it for a small fee for somewhere between 60 and 120 days.
The name also needs a corporate designator: “Incorporated,” “Corporation,” “Company,” or an abbreviation like “Inc.” or “Corp.” That signals to anyone dealing with the business that it’s a limited-liability entity. Certain words are restricted. “Bank,” “Insurance,” “Trust,” and “University” typically require sign-off from another regulator before the Secretary of State will accept your filing, and “Federal” or “National” may trigger additional review.
Appoint a Registered Agent
Every state requires the corporation to name a registered agent (sometimes called a statutory agent or agent for service of process). This is the person or company that receives lawsuits, government notices, and tax mail on the corporation’s behalf. The agent needs a physical street address in the state of formation, not a P.O. box, and has to be available during normal business hours year-round.
You can serve as your own agent, name an officer or employee, or hire a commercial service. Commercial registered agents generally charge $50 to $300 per year. That’s often worth it if you don’t keep a physical office in the state or if you’d rather not have your home address on the public record. Whoever you pick, their name and address end up in the articles of incorporation.
Prepare the Articles of Incorporation
The articles are the founding document that brings the corporation into legal existence. Requirements vary by state, but the core fields are consistent:
- The full corporate name with its designator.
- The registered agent’s name and physical address.
- The number of authorized shares (the maximum the corporation can issue). Many startups authorize a large block, such as 10 million shares, so future investors can be brought in without amending the articles.
- Par value, if any. This is a nominal floor price per share, often $0.001 or $0.01. Some states allow no-par-value stock. Par value can affect franchise tax calculations, so the choice isn’t purely cosmetic.
- The incorporator, meaning the person who signs and files. Their role is temporary; once the board is seated, the incorporator steps aside.
- Initial directors, in states that require them listed. Others let the incorporator appoint the board after filing.
- A purpose statement. Most states accept something general like “any lawful business activity.”
- Duration. Unless you specify a term, the corporation exists perpetually.
One common mistake worth flagging: authorizing a huge number of shares in a state where the annual franchise tax is based on authorized share count. Check how your state calculates that tax before you settle on a number.
File With the State and Pay the Fee
Most Secretary of State offices accept filings through an online portal, and paper filings by mail are still accepted everywhere. Online is faster and usually generates an instant confirmation. Base filing fees for a domestic for-profit corporation generally run from about $35 to $300. A few states tack on additional fees based on authorized shares or stated capital.
Processing times vary. Some states approve online filings within 24 hours; others take several weeks during busy stretches. Expedited processing is usually available for an extra fee. Once approved, you’ll get either a file-stamped copy of the articles or a formal certificate of incorporation. That document is your proof of legal existence, and you’ll need it to open a business bank account, apply for licenses, and sign contracts under the corporate name.
Get a Federal EIN
A new corporation needs an Employer Identification Number from the IRS before it can hire employees, open a bank account, or file a tax return. Think of the EIN as a Social Security number for the business. If you previously ran the same operation as a sole proprietorship, you can’t reuse the old EIN; the corporation is a new taxpayer.
The fastest route is the IRS online EIN application, which issues the number immediately during business hours. You can also apply by fax or mail with Form SS-4. There’s no fee either way.
Handle the Internal Setup
Filing the articles creates the corporation on paper. Making it operational takes a handful of internal steps, and skipping them is one of the more common early mistakes.
Adopt Bylaws
Bylaws are the corporation’s internal rulebook. They cover how directors are elected and removed, what officers the corporation will have and what each one does, how meetings are called and conducted, and how many votes are needed to approve major decisions. Bylaws aren’t filed with the state, but they bind the corporation, its directors, and its shareholders. Most state statutes require them, and their absence is one of the factors courts look at when deciding whether to hold owners personally liable for corporate debts.
Hold the Organizational Meeting
The initial board (or the incorporator, if the articles didn’t name directors) holds an organizational meeting. At this meeting, the board formally adopts the bylaws, appoints officers such as a president, secretary, and treasurer, authorizes stock issuance, approves the form of stock certificate, selects a bank, and sets the fiscal year.
Write the minutes carefully. Courts treat detailed, contemporaneous minutes as strong evidence that the corporation is genuinely separate from its owners. Every resolution, who voted, and the outcome should be recorded.
Issue Stock
Once the board authorizes it, the corporation issues shares to the initial shareholders in exchange for their capital contributions, whether cash, property, or in some cases services. Each shareholder should get a stock certificate, or a written notice if the corporation uses uncertificated shares. Record every issuance, transfer, and cancellation in a stock ledger. That ledger is the definitive record of who owns what and matters enormously in any future sale, audit, or ownership dispute.
Keep a Minute Book
The articles, bylaws, minutes, stock certificates, and stock ledger all belong in one place: a corporate minute book, physical or digital. Investors, lenders, and buyers will ask to see it during due diligence. A disorganized or incomplete minute book suggests the corporation hasn’t been properly maintained, which can undermine the liability shield and cool off deals.
Decide How the Corporation Will Be Taxed
By default, a new corporation is a C corporation for tax purposes: the company pays corporate income tax, and shareholders pay tax again on dividends. Many small businesses prefer S corporation status, which passes income through to shareholders’ personal returns and avoids the double layer.
To qualify as an S corporation, the corporation can have no more than 100 shareholders, only one class of stock, and all shareholders must be U.S. citizens or residents (no partnerships, other corporations, or nonresident aliens).1Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined Married couples and family members can be treated as a single shareholder for the count, so the practical limit can extend past 100 people.
The election is made on IRS Form 2553, and the deadline is strict: no more than two months and 15 days after the beginning of the tax year you want the election to take effect. For a brand-new corporation, that clock starts on the earliest of the date the corporation first had shareholders, first had assets, or began doing business. Miss the deadline and you’ll either wait until the next tax year or apply for late-election relief by showing reasonable cause. An authorized officer has to sign the form; an unsigned Form 2553 isn’t treated as timely even if it arrives on time.2Internal Revenue Service. Instructions for Form 2553
Stay in Good Standing
Incorporation isn’t a one-and-done event. Most states require periodic reports, usually annual, though a few use biennial or longer cycles. These reports update the state on current officers, directors, registered agent, and principal address. Filing fees are typically modest. The consequences of missing them are not.
A corporation that skips its periodic report can lose good standing, which can block it from enforcing contracts, borrowing, or filing lawsuits in state court. Let the delinquency drag on and the state can administratively dissolve the corporation. Reinstatement is usually possible, but it means back fees, penalties, and paperwork, plus the awkward fact that the business may have had no legal authority to operate during the gap.
Many states also charge a separate annual franchise tax. Depending on the state, it’s calculated on authorized shares, net worth, revenue, or as a flat amount, and it’s owed whether or not the corporation made any money. Look up your state’s specifics right after incorporating so you know the amounts and due dates.
Register in Other States Where You Operate
If your corporation is formed in one state but operates in another, you’ll usually need to register as a “foreign corporation” in each state where you do business. “Foreign” here means incorporated elsewhere, not international. The process is called foreign qualification and generally involves filing an application for a certificate of authority, appointing a registered agent in that state, and paying an additional fee.
Not every out-of-state activity triggers this. Occasional transactions, attending trade shows, and maintaining a bank account generally don’t. Having an office, employees, or a warehouse in another state almost certainly does. A corporation that should have qualified and didn’t can be barred from using that state’s courts and can owe back taxes and penalties.
Protect the Liability Shield
The reason to incorporate is limited liability: shareholders generally aren’t personally responsible for the corporation’s debts. Courts can strip that protection, though, through what’s called piercing the corporate veil, if the corporation looks like the owner’s alter ego rather than a real, separate entity.
The behaviors that get owners into trouble are consistent across jurisdictions. Commingling funds, meaning paying personal expenses from the corporate account or depositing corporate income into a personal account, is the fastest way to lose the shield. Ignoring formalities, such as skipping annual meetings, minutes, or bylaws, makes it easier to argue the corporation was never really separate. Undercapitalizing the business, so it never had the money to meet its obligations, can lead courts to conclude the entity was a sham from the start. Misleading creditors about the corporation’s finances is the fourth recurring factor.
The fix is to treat the corporation like a separate person, consistently. Keep a dedicated bank account. Hold and document meetings. Keep the minute book current. Put in enough capital for the business to realistically operate. Courts have little patience for owners who followed the rules for a year and then let things slide.
Beneficial Ownership Reporting
One thing worth clearing up because the rules changed recently: the Corporate Transparency Act originally required most small corporations to file beneficial ownership information reports with the Financial Crimes Enforcement Network. In March 2025, FinCEN issued an interim final rule exempting all domestic reporting companies, meaning entities created by filing with a Secretary of State or similar office under U.S. law.3Financial Crimes Enforcement Network. FinCEN Removes Beneficial Ownership Reporting Requirements for US Companies and US Persons A corporation formed in any U.S. state is not required to file a BOI report with FinCEN.
The reporting obligation still applies to foreign reporting companies, meaning entities formed under the law of another country that register to do business in a U.S. state. Those must file a BOI report within 30 calendar days of registering.4Federal Register.
