What is an S Corporation in the USA?

An S Corporation, also known as a Subchapter S Corporation, is a unique type of business entity that combines the benefits of pass-through taxation with the advantages of operating as a corporation. It offers an attractive choice for many small to mid-size businesses that want the legal protections of a corporation but with a more tax-friendly structure. Here are the main characteristics of an S Corporation:

  • Pass-through Taxation: This is perhaps the most distinctive feature of an S Corporation. Unlike a traditional C Corporation, an S Corporation does not pay federal taxes at the corporate level. Instead, the corporation’s income, losses, deductions, and credits are passed through to their shareholders proportionately, who then report these on their individual income tax returns. This avoids the issue of “double taxation” often associated with C Corporations where income is taxed at the corporate level and again at the individual level when dividends are distributed.
  • Limited Liability Protection: Just like C Corporations, S Corporations provide their shareholders with limited liability protection. This means the owners (shareholders) are typically not personally responsible for the corporation’s debts and liabilities.
  • Restrictions on Ownership: S Corporations face several restrictions on ownership. They can have no more than 100 shareholders. All shareholders must be U.S. citizens or residents, and they cannot be other corporations or partnerships. Also, S Corporations can only have one class of stock.
  • Existence of Corporate Officers: An S Corporation must have duly appointed corporate officers who are responsible for managing the corporation. Often, the officers include a president, vice president, secretary, and treasurer.
  • Adherence to Formalities: S Corporations are required to follow the same corporate formalities as C Corporations. This includes adopting bylaws, issuing stock, holding regular meetings of the board of directors, keeping meeting minutes, and other corporate governance practices.

Differences Between S Corporation and C Corporation

S Corporations and C Corporations are both legal entities that provide their owners (shareholders) with limited liability protection, but they differ significantly in tax treatment, ownership rules, and dividend distribution.Here’s a breakdown of their key differences:

  • Taxation:This is the main difference between an S Corporation and a C Corporation.
    • S Corporation: This is a pass-through tax entity. This means that the corporation itself does not pay federal income tax. Instead, the company’s profits or losses are passed through to its shareholders, who then report this income or loss on their personal tax returns. This approach avoids the “double taxation” that occurs with C Corporations.
    • C Corporation: In contrast, a C Corporation is subject to double taxation. The corporation pays federal income tax on its earnings, and then the shareholders also pay taxes on the dividends they receive from those earnings.
  • Ownership Restrictions
    • S Corporation: There are restrictions on who can own shares in an S Corporation. It can have no more than 100 shareholders, all of whom must be U.S. citizens or residents. S Corporations cannot be owned by C Corporations, other S Corporations, LLCs, partnerships, or many trusts. Also, S Corporations can only have one class of stock.
    • C Corporation: There are no restrictions on ownership for a C Corporation. It can have an unlimited number of shareholders, foreign or domestic, and they can be individuals or other business entities. C Corporations can also have multiple classes of stock.
  • Dividend Distribution
    • S Corporation: Profits and losses must be allocated to shareholders in proportion to their ownership interest. This means if you own 50% of the S Corporation, you must receive 50% of the profits or losses.
    • C Corporation: The corporation’s board of directors has discretion in determining the timing and amount of dividend distributions.

Each type of corporation has its advantages and disadvantages. The best choice for a business will depend on various factors, including the business’s goals, its investment needs, the owners’ personal tax situations, and more. It’s often a good idea to consult with a business advisor or attorney to determine the best entity type for a specific business. Access to more information on LLC VS Corporation.

What Types of Businesses can Choose a S Corporation?

Choosing the right business structure is crucial as it impacts many aspects of a business, including taxation, liability, management structure, and even the ability to raise capital. An S Corporation could be an attractive choice for certain types of businesses:

  • Small to Mid-Sized Domestic Businesses: Given the limitation of 100 shareholders, S Corporations are often best suited to small to mid-sized businesses. The pass-through taxation can be particularly beneficial for these businesses to avoid double taxation.
  • Businesses Seeking Liability Protection: Like C Corporations, S Corporations provide shareholders with limited liability protection, meaning that shareholders are typically not personally responsible for the business debts and liabilities. This makes it a suitable choice for businesses with significant potential liability.
  • Businesses with Stable Ownership: S Corporations are best suited for businesses with a stable ownership structure due to the restrictions on the number and type of shareholders.
  • Professionals Services Firms: Law firms, healthcare practices, consulting agencies, and other professional services often opt for S Corporation status. It allows them to take advantage of the limited liability and pass-through taxation benefits.
  • Companies Looking to Reinvest Profits: If a company plans to reinvest its profits back into the business, an S Corporation can be an excellent choice. The pass-through taxation can avoid the potential double taxation issue that may arise with a C Corporation when profits are retained for reinvestment.
  • Businesses Desiring a Corporate Structure: Companies that prefer a formal structure with a board of directors, corporate officers, and the requirement of regular meetings, would find the S Corporation a good fit.

Legal Requirements for an S Corporation in the USA

Establishing an S Corporation in the USA involves several legal requirements that must be met. Here are some of the key requirements:

  • Eligibility Criteria:
    • The business must be a domestic corporation.
    • There must be 100 or fewer shareholders. Shareholders can be individuals, certain trusts, and estates. They cannot be partnerships, corporations, or non-resident aliens.
    • The corporation can only have one class of stock.
    • The business must not be an ineligible corporation (i.e., certain financial institutions, insurance companies, and domestic international sales corporations).
  • Formation Documents: To become an S Corporation, a business must first be incorporated by filing Articles of Incorporation with the Secretary of State or equivalent state agency where the business is located. 
  • Election of S Corporation Status: Once incorporated, the corporation must submit Form 2553, “Election by a Small Business Corporation,” to the Internal Revenue Service (IRS). The form must be signed by all the shareholders and filed within two months and 15 days from the beginning of the tax year the election is to take effect.
  • Obtain an Employer Identification Number (EIN): An EIN must be obtained from the IRS. This is used for tax filing and reporting purposes.
  • Adopt Corporate Bylaws: Bylaws establish the internal rules of the corporation, such as how and when meetings will be held and the roles and duties of officers.
  • Appoint Directors and Officers: The corporation must have a board of directors and must appoint officers. The directors are responsible for major business decisions, while the officers handle the day-to-day operations.
  • Conduct Regular Meetings: Regular meetings of directors and shareholders must be conducted, and minutes of these meetings must be maintained.
  • Issue Stock: Stock must be issued to the shareholders in exchange for the owners’ capital contributions (cash, property, or services). 
  • Compliance with State Requirements: S Corporations must comply with other state requirements, which may include annual reporting, tax filings, and payment of necessary fees.

It’s important to note that failure to meet these requirements can result in the loss of S Corporation status, so it’s crucial to understand and follow these requirements carefully. It’s often advisable to work with a legal professional or a company like TopFDI to ensure all requirements are properly met.

Steps to Set Up an S Corporation in the USA

Setting up an S Corporation in the USA involves several steps. Here’s a step-by-step guide on how to do it:

  • Choose a Business Name: First, you must choose a unique business name that is not already in use. You can check the availability of a business name by checking with your state’s Secretary of State office. Most states also require that the name ends with a corporate designator, like “Corporation,” “Incorporated,” “Limited,” or an abbreviation of one of these words.
  • File the Articles of Incorporation: Next, you need to file the Articles of Incorporation with the Secretary of State in the state where you plan to base your business. This document includes basic information about your corporation, such as the business name, the name and address of the registered agent, and the number of shares the corporation is authorized to issue.
  • Obtain an Employer Identification Number (EIN): After incorporating, you need to get an EIN from the IRS. This can usually be done online and is free of charge. The EIN is like a Social Security number for your corporation and is used for tax filing and reporting purposes.
  • File Form 2553 with the IRS: To elect to become an S Corporation, you need to file Form 2553, “Election by a Small Business Corporation,” with the IRS. The form must be signed by all shareholders and must be filed no more than two months and 15 days after the beginning of the tax year the election is to take effect.
  • Create Corporate Bylaws: Corporate bylaws outline the operating rules of the corporation. They typically include details about the annual shareholder meeting, the responsibilities of directors and officers, and how the corporation will handle recordkeeping and disputes.
  • Issue Stock: As part of the incorporation process, you’ll issue stock to the initial shareholders. This should be documented with stock certificates and recorded in a ledger.
  • Hold Initial Board of Directors Meeting: The first meeting of the board of directors is when the directors approve the corporate bylaws, appoint corporate officers, set the fiscal year, and approve the issuance of shares of stock. Meeting minutes should be taken and added to your corporate records.
  • Stay Compliant: After forming your S Corporation, you’ll need to stay compliant. This may involve filing an annual report and financial statements with your state, maintaining a registered agent, keeping up with corporate recordkeeping, and other tasks depending on your state’s laws and regulations.

Remember, each state might have slightly different requirements for setting up an S Corporation. It’s always a good idea to check with your Secretary of State or a legal advisor to make sure you’re following all the necessary steps. Services like TopFDI can provide valuable assistance throughout the process, helping to ensure all steps are handled correctly.
