What is an S-Corp?

An S-Corp is often misunderstood as a specific type of business structure you create with the state. It is actually a tax designation.

Technically, it is a closely held corporation that has elected to be taxed under Subchapter S of Chapter 1 of the Internal Revenue Code. When you form a corporation, the default status is a C-Corp. If you want the benefits of an S-Corp, you must file a specific election form with the IRS.

The primary reason founders choose this path is to avoid double taxation.

In a standard C-Corp, the company pays corporate income tax on its profits. Then, when those remaining profits are distributed to shareholders as dividends, the shareholders pay personal income tax on that money. The government taxes the same dollar twice.

An S-Corp changes that flow.

When you elect S-Corp status, the corporation itself generally does not pay income tax. Instead, the profits and losses pass through the business directly to the owners’ personal tax returns.

You pay tax on the income at your individual income tax rate. This flow is similar to how a sole proprietorship or a partnership is taxed, but you retain the legal liability protection of a corporation.

This structure can result in significant tax savings for profitable businesses that are not looking to retain earnings within the company for long term growth.

The IRS does not allow just anyone to file for this status. There are rigid constraints that you must navigate.

• Shareholder Limit: You cannot have more than 100 shareholders.
• Citizenship: Shareholders must be U.S. citizens or residents. You cannot have foreign investors.
• Ownership Type: Shareholders must be individuals, certain trusts, or estates. Corporations and partnerships cannot be shareholders.
• Stock Classes: You can only have one class of stock. You cannot issue preferred stock with different dividend rights.

These limitations are critical to consider if you plan to scale rapidly or raise capital.

If your goal is to build a high growth startup that raises money from Venture Capitalists or institutional investors, an S-Corp is likely the wrong choice.

VC firms usually require preferred stock, which allows them to have liquidation preferences and other protective rights. Because S-Corps are legally restricted to a single class of stock, this creates an immediate conflict.

Furthermore, many institutional investors are technically ineligible to be shareholders in an S-Corp due to the restrictions on ownership types.

If you start as an S-Corp and later decide to raise funding, you will almost certainly have to go through the legal expense of converting back to a C-Corp.

One area that catches many new founders off guard is the payroll requirement.

If you are a shareholder actively working in your S-Corp, the IRS requires you to pay yourself a reasonable salary. You must withhold federal and state taxes just like a regular employee.

You cannot simply take all the money out as a distribution. This adds an administrative layer of running payroll, paying unemployment taxes, and filing quarterly payroll reports.

Founders must weigh the tax savings of the pass through status against the added complexity and cost of maintaining a compliant payroll system.
