What it means
Think of the articles as the birth certificate of a corporation. They are short, public and deliberately high level, usually covering the corporate name, the registered agent who accepts legal papers, the stated business purpose, and the number and class of shares the company may issue.
Anyone can look them up on the registry's website, which is exactly why sensitive commercial detail is kept out of them. For a founder, the filing date is the moment personal liability separates from business liability.
Before that date, debts and lawsuits land on the owners personally; afterwards they generally land on the corporation, provided the company is genuinely run as a separate entity with its own bank account and records. Banks, investors, landlords and payment processors nearly always ask for a copy of the articles before opening an account or signing an agreement, because it is the cleanest proof the entity exists.
Lawyers read the share provisions closely, since the number of authorised shares caps how much stock can be issued to employees and investors without an amendment. Amending later is possible but needs a board and shareholder vote plus a fresh filing fee, so it is worth getting the share count roughly right at the start.
Some jurisdictions call the identical document a Certificate of Incorporation or a corporate charter, and the required contents vary a little from place to place. None of these should be confused with the bylaws, which are the internal rulebook covering meetings, officer roles and voting procedures and are not normally filed publicly.
Founders often ask how many shares to authorise. A common approach is to authorise a large round number, such as ten million, so there is room for an employee option pool and later funding rounds, while actually issuing only a fraction of them on day one.
In several states the annual franchise tax is calculated from authorised shares and par value, so the number chosen carries a small ongoing cost.
In practice
Real-world examples
Example 1
A two-person software startup files articles in Delaware authorising 10,000,000 shares of common stock. Eighteen months later a venture investor wants preferred shares, so the company must amend the articles to create a new share class before the money can be wired.
Example 2
A family bakery converts from a sole trader to a corporation and files articles naming the owner's accountant as registered agent. The bank then reopens the trading account in the corporation's name, and the owner's home stops being exposed to supplier credit.
Example 3
A regional logistics firm is acquired, and the buyer's lawyers pull the seller's articles from the public registry during due diligence. They find the authorised share count was never increased after two option grants, which means some employee options were issued over the limit and need a corrective amendment before closing.
Think of it
The articles of incorporation are like the architectural blueprint for a house. They set the foundational walls, define the address, and establish the main rooms before anyone moves in or decorates.
Formula
Calculation
The articles themselves are a legal document, but two numbers inside them drive the opening equity entries:
Aggregate par value = Authorised shares x Par value per share
Additional paid-in capital = Cash received for shares - (Shares issued x Par value per share)
Suppose a founding team authorises 10,000,000 shares with a par value of $0.0001 each. Aggregate par value of the authorised block is 10,000,000 x $0.0001 = $1,000, which is the figure some franchise tax formulas start from. The founders then issue 8,000,000 of those shares to themselves for $0.001 per share, raising 8,000,000 x $0.001 = $8,000 in cash. Of that, 8,000,000 x $0.0001 = $800 is recorded as common stock at par, and the remaining $8,000 - $800 = $7,200 is recorded as additional paid-in capital. The other 2,000,000 authorised shares stay unissued and available for a future option pool.Case study
Seen in the real world
Harbour Lane Robotics is a fictional company used here purely as an illustrative example. Two engineers spent a year selling prototype inspection drones as a partnership, invoicing customers personally and splitting the proceeds. When a warehouse client asked for $2m of liability cover and a corporate counterparty, they filed Articles of Incorporation authorising 10,000,000 shares at $0.0001 par and issued 8,000,000 between them for $8,000 in cash.
The filing changed more than the letterhead. The bank issued a corporate account, the insurer wrote the policy in the company's name, and the two founders stopped signing customer contracts as individuals. Their accountant recorded $800 as common stock and $7,200 as additional paid-in capital, and the 2,000,000 unissued shares later became the option pool for their first four hires.
Eighteen months on, an investor asked for a preferred share class that the original articles did not contemplate. Because the founders had kept board minutes and a clean share register, the amendment took three weeks rather than three months, and this illustrative story ends with the round closing on schedule.
Watch out
Common mistakes
- Treating the articles as the whole legal set-up. They create the entity, but bylaws, a share register, board minutes and an operating bank account are what actually keep liability separate.
- Authorising only the shares needed today. Increasing the authorised count later requires a formal amendment and fee, and it usually surfaces at the worst possible moment, mid-fundraise.
- Putting confidential business detail into the purpose clause. The document is public, so a narrow, specific purpose can also restrict what the company is permitted to do later.
Questions
People also ask
Are the articles the same as a business licence?
No, they create the legal entity, while licences and permits give permission to carry out particular activities and are issued separately.
Who can see our Articles of Incorporation?
Anyone, because they sit on a public registry, which is why commercially sensitive terms belong in private documents such as bylaws or shareholder agreements.
What happens if we move the company to another state?
You either register as a foreign entity in the new state or formally redomicile, and both routes involve a new filing rather than an edit to the original articles.
