Most S corporations start with somewhere between 1,000 and 10,000 authorized shares. The right number for your business depends on how many founders you have, whether you expect to bring in more owners later, and how your state calculates franchise tax. Federal tax law actually simplifies the decision compared to a C corporation, because an S corporation can only have one class of stock and no more than 100 shareholders, so you’re not designing around venture rounds or thousands of micro-investors.
Authorized Shares Are a Ceiling, Not a Distribution
Your corporate charter sets an authorized share count. That’s the maximum number of ownership units the company can ever hand out without amending its formation documents. You don’t have to issue all of them on day one, and most founders shouldn’t.
Issued shares are the ones actually given to founders or investors in exchange for cash, property, or services. The gap between authorized and issued is your reserve. If you authorize 10,000 and issue 7,000 across the founding team, the remaining 3,000 sit available for a future hire, a new investor, or a spouse joining the cap table. Keeping that cushion means you can add an owner without going back to the state to amend your charter.
Common Starting Numbers and What They’re Good For
For most S corporations with a small founding team, 1,000 to 10,000 authorized shares is the sweet spot. Here’s how those numbers play out.
- 1,000 shares. Clean math for two or three founders. A 51/49 split is 510 and 490. A three-way equal split is 334, 333, 333. This is the most common choice for S corporations that plan to stay small.
- 10,000 shares. More room for small equity grants to future employees or advisors without creating awkward fractions. A 1% stake is exactly 100 shares.
- 100,000 or more. Occasionally useful if you plan to add many shareholders over time, but remember the 100-shareholder cap and the franchise-tax implications below. Most S corporations don’t need this many.
Share count doesn’t set the value of the company. A business with 1,000 shares isn’t worth more or less than the same business with 10,000. Share count just decides how finely ownership gets sliced.
Setting Par Value
Par value is the minimum legal price at which a share can be sold. Most small corporations set it very low: $0.01, $0.001, or even $0.0001 per share. A low par value keeps required initial capital contributions minimal. Authorize 10,000 shares at $0.001 par value and total par capital is just $10. Founders typically have to pay at least par value when they buy their initial shares, so a negligible par avoids demanding a real cash infusion before the business has any revenue.
Some states let corporations issue no-par-value stock, which sounds convenient until you see how it affects franchise tax. In states that use an asset-based formula, no-par shares are sometimes assigned a default value that inflates the tax bill. A tiny stated par value tends to produce a more predictable and lower result than leaving par unspecified. Check your state’s method before deciding.
Why State Franchise Tax Should Drive the Number
This is where founders get tripped up. Several states calculate their annual franchise tax based on how many shares you authorize in your charter, not how many you actually issue. Under what’s commonly called the Authorized Shares Method, the tax bill climbs as you add shares. A corporation with a few thousand authorized shares might owe a minimum fee well under $200, while one that casually authorized ten million could face a bill in the six figures.
Other states use a formula that factors in total assets alongside share count, sometimes called the Assumed Par Value Capital Method. Under that approach, a high share count paired with low assets can still land you in a high tax bracket. Either way, don’t authorize millions of shares because it sounds impressive. If your state ties franchise tax to share count, that decision has a real annual cost. Some states don’t impose a separate franchise tax at all; others charge minimums that can run anywhere from nothing up to several hundred dollars per year. Look up your state’s method before you file.
S Corporation Rules That Shape the Decision
Federal tax law puts tighter rules on S corporation stock than on regular C corporations, and those rules directly affect how you set up your shares.
- One class of stock. Every share must carry identical rights to distributions and liquidation proceeds. You cannot create preferred shares with special dividend rights the way a C corporation or venture-backed startup would.1Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined
- 100-shareholder cap. The company cannot have more than 100 shareholders at any time. For most small businesses this is never an issue, but it means the share count doesn’t need to accommodate thousands of tiny investors.1Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined
- Eligible shareholders only. Owners must be U.S. citizens or resident individuals, certain trusts, or estates. Partnerships, corporations, and nonresident aliens cannot hold shares.2Internal Revenue Service. S Corporations
Voting and Non-Voting Shares Are Allowed
One wrinkle that surprises many founders: you can issue shares with different voting rights without violating the one-class-of-stock rule. Treasury regulations state that differences in voting rights are disregarded when determining whether a corporation has more than one class of stock.3eCFR. 26 CFR 1.1361-1 – S Corporation Defined A husband-and-wife team can give one spouse voting shares and the other non-voting shares, and the S election stays intact as long as every share receives equal distributions and liquidation proceeds. That flexibility means you don’t need to inflate the share count to solve control questions.
What You Actually Put on the Articles of Incorporation
The articles of incorporation (called a certificate of incorporation or certificate of formation in some states) are what actually creates your corporation. The stock information you’ll provide is short:
- Total authorized shares. The maximum number the corporation can issue.
- Stock class. For an S corporation, this is simply “Common.” No preferred classes.
- Par value. The minimum stated value per share, or a designation of no-par if your state allows it and you’ve decided that’s the right call.
Pull the current formation forms from your state’s business filing office, usually the Secretary of State website, rather than relying on third-party templates. Double-check the share count and par value entries before filing, because corrective amendments cost money and create delays.
After the state accepts your articles, the board should formally authorize the issuance of shares to each founder by resolution. Record who received how many shares, what they paid or contributed, and the date. Keep a stock transfer ledger that tracks every ownership change from that point forward.
You Can Add More Shares Later, but It Costs Something
If you start with 1,000 authorized shares and eventually need more, you can amend your articles to raise the ceiling. The process typically requires a board resolution, shareholder approval, and filing the amendment with your state’s business filing office. Amendment fees vary by state but generally fall in the $30 to $150 range.
The shareholder vote requirement is worth keeping in mind. With two founders, approval is trivial. As the shareholder count grows, coordinating a vote takes more effort and may require formal notice under your bylaws. Authorizing a reasonable cushion of unissued shares at formation, say 10,000 when you only plan to issue 6,000 initially, avoids this hassle for early-stage growth.
And if your state uses the authorized-shares method for franchise tax, raising your authorized number also raises your annual tax bill. Factor that recurring cost into the decision, not just the one-time amendment fee. For most founders, starting at 1,000 or 10,000 shares with a token par value and a healthy unissued reserve is the right call, and it’s easy to change if the business grows into something bigger than you first planned.
