As an entrepreneur, one of the most critical decisions you'll make is choosing the right business structure for your enterprise. Your selection will significantly impact your operations, management, legal, and tax considerations, both now and in the future. Among the plethora of business structures available, a standout choice is the S Corporation or S- Corp.

In this comprehensive guide, we will delve into everything you need to know about S Corporations: what they are, their advantages and disadvantages, and the process of becoming one.

What is an S Corporation?

An S Corporation, often abbreviated as an S Corp, is a unique type of corporation that falls under Subchapter S of Chapter 1 of the Internal Revenue Code. The S Corp structure allows corporations with 100 shareholders or less to enjoy the benefits of incorporation while being taxed as a partnership.

In essence, an S Corp is a business entity that elects to pass corporate income, losses, deductions, and credits through its shareholders for federal tax purposes. This structure provides the advantage of limited liability protection and avoids the issue of double taxation, which is common with traditional corporations.

Setting up an S Corporation

Before you can become an S Corporation, your business must first be established as a corporation. This process involves filing and submitting necessary documents such as the Articles of Incorporation or Certificate of Incorporation to the appropriate government authority, along with the applicable fee.

Once the incorporation process is complete, all shareholders must sign and submit Form 2553 to be granted the S Corporation designation. From here on, taxes are handled by the corporation's shareholders on their individual returns.

S Corporation Eligibility Criteria

According to the Internal Revenue Service (IRS), to qualify for S Corporation status, the corporation must meet the following criteria:

  • The corporation must be domiciled in the United States.

  • The corporation can only have allowable shareholders, which may include individuals, certain trusts, and estates.

  • Partnerships, corporations, or non-resident alien shareholders are not permitted. The corporation must have 100 or fewer shareholders.

  • The corporation can only have a single class of stock.

  • The corporation must not be an ineligible corporation. Certain financial institutions, insurance companies, and domestic international sales corporations are not permitted to use the S Corporation structure.

Advantages of an S Corporation Structure

One of the main advantages of an S Corporation is that it allows the business to avoid double taxation. Double taxation occurs when corporate income is taxed at the corporate level and then again at the individual level when it is distributed as dividends to shareholders.

In an S Corporation, corporate income, losses, deductions, and credits are passed through to shareholders, who then report these amounts on their personal income tax returns. This pass-through taxation allows S Corporations to avoid paying federal income tax at the corporate level. Instead, taxes are paid at the individual level by the shareholders.

Another significant advantage of an S Corporation is limited liability protection. Shareholders of an S Corporation are not personally responsible for the corporation's debts and liabilities. This protection is an essential feature for many business owners and can be a significant factor in choosing the S Corporation structure.

Disadvantages of an S Corporation

While there are many advantages to the S Corporation structure, there are also some potential drawbacks to consider. One of the main disadvantages is the restriction on the number and type of shareholders. S Corporations are limited to 100 shareholders, and all shareholders must be individuals, certain trusts, and estates. This limitation can hinder the ability of the corporation to raise capital.

Another potential drawback is the single class of stock restriction. Unlike other types of corporations, S Corporations cannot issue different classes of stock with different voting rights or dividend rates. This limitation can reduce the corporation's flexibility in terms of ownership and control.

Finally, S Corporations face several ongoing compliance requirements. These requirements include annual reporting, shareholder meetings, and maintaining corporate records. Non-compliance with these requirements can result in the loss of S Corporation status.


The decision to become an S Corporation is not one to be taken lightly. It requires careful consideration and a thorough understanding of the legal, tax, and operational implications. While the S Corporation structure offers many advantages, it is essential to weigh these against the potential drawbacks before deciding if this is the right business structure for your enterprise.

As always, it is recommended to seek professional advice from a tax or legal expert when making significant decisions about your business structure. With the right guidance, you can make an informed decision that will set your business up for success.
