Few things trip up new founders faster than the difference between authorized and outstanding shares. The terms sound interchangeable, they show up on the same cap table, and getting them backwards can lead to bad math on ownership, dilution, and even your tax bill. They are not the same thing, and the gap between them is where a lot of equity decisions actually live.
This guide untangles authorized and outstanding shares, explains where issued shares fit in the middle, and shows why these numbers drive your cap table, your fundraising, and your Delaware franchise tax. By the end, you will read a capitalization table the way an investor does.

What You’ll Learn
Authorized and Outstanding Shares Explained
Authorized shares are the maximum number of shares a corporation is legally allowed to issue under its charter. Outstanding shares are the shares that have actually been issued and are currently held by shareholders. The authorized number is a ceiling; the outstanding number is reality at a given moment.
Here is the simple way to picture it. If your certificate of incorporation authorizes 10 million shares and you have issued 8 million to founders and investors, you have 8 million outstanding shares and 2 million still available to issue. Understanding authorized and outstanding shares is the foundation for reading any cap table, and it connects directly to the concepts in our guide on outstanding vs. fully diluted ownership.
Issued Shares: The Piece in the Middle
Issued shares are the shares the company has actually distributed to owners, whether or not the company later bought some back. In most early-stage startups, issued and outstanding are the same number. They only diverge when a company repurchases stock and holds it as treasury shares, which are issued but no longer outstanding.
According to the U.S. Securities and Exchange Commission’s investor glossary, outstanding shares are those held by all shareholders, including restricted shares owned by insiders. That distinction matters when you calculate ownership percentages, because you divide by the right denominator only if you know which number you are using.
Why the Numbers Matter for Your Cap Table
Ownership percentage is a fraction, and the denominator is everything. Divide by outstanding shares and you get today’s ownership. Divide by fully diluted shares, which include options and convertible securities, and you get the picture after everyone exercises. Confusing the two is how founders accidentally over-promise equity.
This is also why instruments that convert later, like a convertible note or SAFE, deserve careful modeling. They are not outstanding shares today, but they will be, and they dilute everyone when they convert. A clean understanding of authorized and outstanding shares keeps your company’s legal map honest as you raise money.
Authorized Shares and Delaware Franchise Tax
Here is a practical reason the authorized number matters: Delaware taxes it. Delaware offers two franchise tax methods, and the authorized shares method charges more as your authorized count climbs. A corporation with 5,000 authorized shares or fewer pays the $175 minimum, while the tax rises by roughly $85 for each additional 10,000 authorized shares.
Startups that authorize 10 million shares can see an eye-watering bill under that method, which is why most use the alternative. According to the Delaware Division of Corporations, corporations may instead use the assumed par value capital method, with a $400 minimum, and pay whichever method produces the lower tax. The maximum standard franchise tax is $200,000, rising to $250,000 for large corporate filers. The takeaway: your authorized share count is not just a legal detail, it has a dollar cost.
5 Costly Mistakes Founders Make with Shares
The confusion around authorized and outstanding shares shows up as the same recurring errors.
- Authorizing too few shares: Running out of authorized shares mid-raise forces a charter amendment at the worst possible time.
- Issuing 100% of authorized shares: Leaving no room for an option pool or new investors boxes the company in.
- Confusing outstanding with fully diluted: Promising percentages against the wrong number over-commits equity you do not have.
- Ignoring the franchise tax impact: Sky-high authorized counts can spike Delaware taxes if you use the wrong calculation method.
- Sloppy record-keeping: A cap table that does not reconcile with the corporate stock ledger is a red flag in every financing and sale.
Reserved Shares and the Option Pool
Between authorized and outstanding sits another category: reserved shares. These are authorized shares set aside for a specific future use, most often an employee equity plan. They are not outstanding until the options are granted and exercised, but they are spoken for.
Sizing the pool is a negotiation, and it dilutes existing holders, as we explain in why the employee option pool is not free. The price at which those shares get issued ties back to valuation, which is the subject of our comparison of 409A valuation vs. preferred stock valuation. Regulated operators structuring ownership across entities, such as a cannabis holding company structure, have to track authorized and outstanding shares at every layer of the org chart.
How to Read a Cap Table Line by Line
A capitalization table is just a ledger of who owns what, but reading it well takes a little practice. The top of the table usually lists the number of authorized shares, then breaks the issued stock into founders, employees, and investors. The sum of those issued blocks is your outstanding count, and the space between outstanding and authorized is your remaining runway to issue more.
When you review a cap table, start by confirming that the authorized and outstanding shares reconcile with the corporate stock ledger and the board resolutions that approved each issuance. If a grant appears on the cap table but was never formally approved, you have a cleanup problem that will surface in diligence. A tidy table lists share class, issue date, price per share, and any vesting, so a reader can trace every block of stock back to a document.
Investors read the fully diluted column first, because that is the ownership picture after options and convertibles come into play. Founders who only track outstanding shares are often surprised by how much their percentage shrinks once the pool and the notes are layered in.
Authorized and Outstanding Shares in Fundraising
Every priced round touches your authorized and outstanding shares. New investors buy newly issued preferred stock, which increases the outstanding count and dilutes existing holders. If you do not have enough authorized but unissued shares to complete the round, you have to amend the charter first, which costs time and legal fees at exactly the moment momentum matters most.
Smart founders authorize enough shares at formation to accommodate several rounds and an option pool, without authorizing so many that Delaware franchise tax becomes a nuisance. That balance is a planning decision, not an afterthought. Model the next two rounds, decide how big the pool needs to be, and set the authorized number with that map in hand. Do it once at the start and you avoid a string of amendments later, each of which requires board and stockholder approval.
Frequently Asked Questions
What is the difference between authorized and outstanding shares?
Authorized shares are the maximum number a corporation can issue under its charter. Outstanding shares are the shares actually issued and currently held by shareholders. Authorized is the ceiling; outstanding is what has been used so far.
Are issued and outstanding shares the same?
Usually, but not always. They are identical until a company repurchases stock and holds it as treasury shares. Those shares remain issued but are no longer outstanding, so the two numbers can diverge.
Do authorized shares affect my taxes?
In Delaware they can. The authorized shares method of franchise tax charges more as your authorized count rises. Most startups use the assumed par value method instead and pay whichever calculation is lower.
Next Steps
Authorized and outstanding shares are simple once you see how the ceiling, the issued stock, and the reserved pool relate. Getting the structure right at formation saves painful amendments and cap table cleanups later.
