A corporation’s share structure has two moving parts that the articles of incorporation must spell out: the total number of authorized shares and the par value assigned to each one. Get both right at formation and you have room to raise money, grant equity, and keep annual franchise taxes reasonable. Get them wrong and you pay for the mistake through higher taxes, awkward equity math, or a charter amendment every time you want to do something new.
What Authorized Shares Are
Authorized shares are the maximum number of equity units the corporation is legally permitted to issue. The number lives in the articles of incorporation (called a certificate of incorporation in some states) and becomes part of the public record when the state accepts the filing. It functions as a hard ceiling. The company can issue fewer shares than the authorized number, but never more, unless the founders amend the charter.
Every state’s incorporation statute requires this figure. If the company will have more than one class of stock, the charter also has to break the authorized total down by class. The point of the requirement is transparency: investors, regulators, and creditors can always see the outer limit of how much equity the company can put into circulation.
Authorizing a number does not mean issuing that number. Most corporations authorize far more shares than they distribute at formation and hold the surplus in reserve for future fundraising rounds, employee equity grants, and acquisitions. That reserve is what keeps you from filing a charter amendment every time a new investor comes in or a key hire wants stock options.
What Par Value Is
Par value is the minimum price printed on each share of stock in the corporate charter. Historically it worked as a creditor protection floor: a corporation could not sell shares below par, and the total par value of issued shares became “stated capital” that could not be paid out as dividends. Creditors treated that cushion as a baseline guarantee that some assets would stay in the business.
As a measure of what a share is actually worth, par value has become almost meaningless. Most corporations set it at a fraction of a penny, commonly $0.001 or $0.0001, purely to satisfy the statutory filing requirement while preserving pricing flexibility. A share with a $0.0001 par value can still be sold to an investor for $5, $50, or $500. The difference between what the investor pays and the par value goes on the books as additional paid-in capital.
Most states also allow no-par-value stock, which eliminates the floor entirely. When shares have no par, the board sets the issuance price based on negotiation, market conditions, or a fair-value assessment. No-par stock simplifies some accounting but can change how franchise tax is calculated depending on the state of incorporation.
How Many Shares to Authorize
For startups, 10 million authorized shares has become the industry standard, and the reason is arithmetic. That number is large enough that small ownership stakes still produce clean vesting schedules. If you authorize only 1,000 shares and want to grant an employee 0.1% of the company, that is a single share vesting over four years, with awkward monthly rounding. With 10 million shares, the same 0.1% is 10,000 shares vesting roughly 208 shares per month.
Option pool math pushes in the same direction. Most venture-backed startups reserve roughly 10% to 20% of authorized shares for employee equity grants. Those shares need to exist in the authorized-but-unissued pool before the board can promise them. If you did not authorize enough shares upfront, you have to amend the charter before you can expand the pool, which means legal fees, board resolutions, and a shareholder vote.
What Par Value to Set
For a typical startup the answer is: as low as your state allows, usually $0.0001. A very low par value keeps every share priced flexibly, keeps stated capital from becoming a distribution constraint later, and, in most states, keeps franchise tax formulas working in your favor.
No-par stock is a defensible alternative in states where it does not disadvantage you on tax. The tradeoff is that the board has to affirmatively fix a price for each issuance, and some accounting treatments become slightly less clean. Neither choice is universally correct; it depends on the state of incorporation.
Franchise Tax Consequences
This is where the two decisions above stop being paperwork and start showing up on a bill. Several states, Delaware most prominently, calculate annual franchise tax based partly on authorized shares. Authorizing 10 million shares can produce a meaningfully higher tax bill than authorizing 5,000 under one method.
The saving grace is that these states usually offer an alternative calculation that factors in issued shares, par value, and total assets rather than just the authorized count. A low par value can drop the alternative-method tax substantially, which is one more reason most startups choose $0.0001 rather than $1.00. Run both calculations during the formation process. The interplay between authorized shares, par value, and your state’s specific franchise tax formula is one of the first things worth getting right, because it recurs every year.
Tracking Shares After You Issue Them
Once shares leave the authorized pool, they fall into categories that matter for voting, dividends, and compliance.
- Issued shares are any shares that have been formally distributed to a shareholder in exchange for cash, property, or services. Once issued, a share stays “issued” on the books even if the company later buys it back.
- Outstanding shares are the subset of issued shares currently held by shareholders. These carry voting rights and dividend eligibility.
- Treasury shares are shares the corporation once issued but reacquired through a buyback or forfeiture. They remain classified as issued but lose voting rights and dividend eligibility until the company reissues or retires them.
The arithmetic: outstanding shares plus treasury shares equals issued shares, and issued shares can never exceed authorized shares. A corporation with 10 million authorized that has issued 4 million and bought back 500,000 has 3.5 million outstanding, 500,000 in treasury, and 6 million authorized but unissued.
State statutes generally let a corporation accept cash, property (including intellectual property), and services already performed as payment for shares. Promissory notes and future services are more restricted, and some states prohibit them outright. The board is responsible for determining that the consideration is adequate, and that determination is usually treated as conclusive absent fraud.
Overissuance
Issuing more shares than the charter authorizes is not a technical foot fault. Overissued shares are void from the moment they are created. A person holding them has no voting rights, no dividend rights, and no legitimate ownership, even if they paid full price. Directors who approve an issuance beyond the authorized ceiling face personal liability for breach of duty, and shareholders can seek an injunction before shares change hands or hold directors accountable after the fact. Some states have adopted statutory procedures for ratifying defective acts including overissuances, but ratification requires board and shareholder approval and is not guaranteed to work, especially over shareholder objection. The cleaner path is to track the ceiling and amend before you promise shares you do not have.
Classes of Stock and the Rights That Go With Them
Most corporations divide equity into at least two classes, each aimed at a different type of holder.
Common stock is the default ownership interest. Common shareholders vote on board elections and major corporate decisions and benefit most when the company’s value grows. The tradeoff is that they stand last in line if the company fails. In a liquidation, creditors get paid first, then preferred shareholders, and common holders receive whatever is left, which is often nothing.
Preferred stock trades upside for downside protection. Preferred shareholders typically receive dividends before common holders and get priority on remaining assets during a dissolution or acquisition. The specific terms depend entirely on the corporate charter, which is why preferred stock can look dramatically different from one company to the next.
Liquidation Preferences
The most consequential term attached to preferred stock is the liquidation preference. A “1x” preference means the investor gets their original investment back before common holders see anything. A “2x” preference means they get double.
The preference is also either participating or non-participating. With a non-participating preference, the investor takes the greater of the preference amount or their proportional share of total proceeds as if they had converted to common. With a participating preference, the investor collects the preference amount and then also shares in the remaining proceeds alongside common shareholders, which is why participating preferences are sometimes called double-dip provisions. For founders, this distinction can be the difference between a meaningful payout and walking away with almost nothing after a modest exit.
Dual-Class Voting Structures
Some corporations create multiple classes of common stock with different voting rights. In a dual-class structure, one class might carry 10 or 50 votes per share while the other carries one. Founders and early insiders typically hold the high-vote class, letting them keep control after selling a majority of the economic ownership to outside investors.
The structure insulates founders from short-term shareholder pressure and makes hostile takeovers extremely difficult, but it also limits public investors’ ability to hold leadership accountable, which is why institutional investors have pushed back. Sunset provisions that collapse all shares into a single class after a set number of years, or when the founder leaves, are one response. Institutional investors generally consider seven years or fewer reasonable, though many companies set longer timelines or tie the sunset to management departure rather than a fixed date.
Dilution and Preemptive Rights
Every new share issuance shrinks the ownership percentage of existing shareholders. If you own 100,000 shares out of 1 million outstanding (10%) and the company issues another 500,000, your 100,000 shares now represent 6.7% of the company. Your count did not change; your slice did. That is dilution.
Preemptive rights are the traditional defense. When a corporation grants preemptive rights, existing shareholders get the first opportunity to buy newly issued shares in proportion to their current ownership before those shares go to outsiders. Own 10%, and you can buy 10% of the new issuance at the offering price to hold your stake.
In most states, preemptive rights no longer exist by default. They have to be written into the charter, and many venture-backed companies deliberately leave them out because they complicate fundraising. Without preemptive rights in the charter, the board can issue shares to anyone at any price without offering them to existing holders first. Investors who want anti-dilution protection usually negotiate it separately in investment agreements rather than relying on the charter.
Authorizing Shares Is Not the Same as Being Allowed to Sell Them
A stamped certificate from the Secretary of State does not clear you to sell stock. Federal securities law is a separate, overlapping regime. Under the Securities Act of 1933, it is unlawful to sell or offer to sell a security through interstate commerce unless a registration statement is in effect with the SEC or the transaction qualifies for an exemption.1Office of the Law Revision Counsel. 15 USC 77e – Prohibitions Relating to Interstate Commerce and the Mails “Interstate commerce” is read broadly enough to cover essentially any transaction involving email, a phone call, or a bank wire.
Full SEC registration is expensive, so most private companies rely on the exemption for transactions “not involving any public offering,” which the SEC has developed through Regulation D.2Office of the Law Revision Counsel. 15 USC 77d – Exempted Transactions Regulation D offers several pathways with different dollar caps, advertising rules, and investor qualification standards, and the SEC publishes the current requirements for each.3U.S. Securities and Exchange Commission. Exempt Offerings Most states also impose their own “blue sky” registration or notice filing requirements on top of federal law. Issuing stock without clearing both levels can create rescission rights for investors, civil penalties, and in serious cases criminal liability. This is the point in formation where competent securities counsel earns its fee.
What the Articles of Incorporation Have to Say
The share structure provisions in the articles of incorporation are among the most important things in the document. At minimum, the filing must include:
- The total number of authorized shares across all classes.
- The par value per share for each class, or a statement that shares are issued without par value.
- If there is more than one class, the number of shares in each class and a description of the distinct rights attached to each, including voting power, dividend priority, conversion rights, and liquidation preferences.
Most states provide standardized forms through the Secretary of State’s office with specific fields for this information. Electronic filing is now the norm, with turnaround from same-day to several business days depending on the state and whether you pay for expedited review. Standard incorporation filing fees generally fall in the range of $50 to $300.
Incomplete or inconsistent share information is a common reason filings get rejected. If class-level share counts exceed the stated total, or a class of stock appears without a description of its rights, the filing office sends it back. More dangerous is ambiguous charter language about rights and preferences, which can fuel shareholder disputes years later when real money is on the line. Precision here is cheaper than litigation later.
Changing the Share Structure Later
None of these decisions is permanent. As the company grows, founders commonly need to authorize more shares, create a new class for a fundraising round, or adjust par value. Each change requires a formal amendment to the articles of incorporation.
The amendment process usually follows a two-step pattern: the board adopts a resolution proposing the change, and then shareholders entitled to vote approve it, typically by a majority of outstanding shares. The corporation then files a certificate of amendment with the state. State filing fees for amendments are generally modest, but total costs including legal work to prepare board resolutions, shareholder consents, and the amendment itself can add up, especially with multiple investor classes that have separate approval rights.
If an amendment changes the authorized share count or par value partway through a tax year, some states require the corporation to prorate its franchise tax calculation, computing tax separately for each portion of the year the old and new structures were in effect. Missing this step can produce an unexpected bill or penalty. Founders who expect to need more shares within the next year or two are often better off authorizing them upfront, provided the higher count does not trigger a disproportionate franchise tax bill in the state of incorporation.
