Everything You Need to Know about Forming an S Corporation

Starting a business is exciting, but getting all the legalities in order that come with launching a business entity, can be daunting.

We take a look at S corp and business structures and how business owners can go about establishing if this entity type suits their business needs.

What is an S corp business?

S corporations are corporations that elect to pass corporate income, losses, deductions, and credits through to their shareholders for federal tax purposes.

Both C corporations and S corporations are born the same way – by filing Articles of Incorporation with the state in which the business will be located. Note that a business organized as a limited liability company can also elect to be treated as an S corporation for tax purposes.

(Remember that the terms “C corporation” and “S corporation” are tax terms, not legal terms.)

Once a business has incorporated, it can choose to be taxed either as a C corporation or S corporation.

If the business wants to be taxed as a C corporation, nothing further needs to be done. The default tax entity for an incorporated business is the C corporation.

If the business wants to be taxed as an S corporation, Form 2553 (“Election by a Small Business Corporation”) needs to be filled out and submitted to the IRS. Filling out Form 2553 and submitting it to the IRS is also referred to as “making an S-election.”

As with any other IRS form, there is a deadline to submit Form 2553. The general deadline to submit an S-election is the due date for the S corporation’s tax return. For an S corporation with a December 31 year-end, the deadline to submit both the tax return and S-election is March 15th.

Simple business structures

If you wanted to start a business in the first half of the 20th century, you had two options:

  1. Form a C corporation to take advantage of liability protection but be subjected to two layers of federal tax at the corporate and individual level, or…
  2. Choose to be a sole proprietorship or partnership, enjoy the benefit of a single layer of taxation, but forgo the liability protection afforded C corporations.

Neither of these choices was favorable for small and family-owned businesses. In 1946, the Department of Treasury suggested the third choice of entity, one that combined the liability protection of a C corporation with the single layer of taxation from sole proprietorships or partnerships.

Understanding why the S corp entity was formed

U.S. taxpayers waited another 12 years before this suggestion of a hybrid entity actually came to fruition. In 1958, Congress and President Dwight Eisenhower created Subchapter S of the tax code. Subchapter S provided the benefit of limited liability that C corporations have while maintaining the tax benefits of sole proprietorships and partnerships.

The S corporation was created to address the specific problems faced by small businesses looking to enter markets dominated and controlled by large corporations.

There were four trade-offs, however, to using the new S corporation entity structure:

  • Must be a domestic business
  • Have a limitation on the number of shareholders it is allowed to have
  • Have limitations on who could be a shareholder
  • Can only have one class of stock

For many small businesses in the mid-20th century, these limitations were often never an issue.

Former Internal Revenue Service commissioner Don Alexander described the S corporation as “a simple structure for simple people” and simple businesses during Congressional testimony in 2006.

Starting an S corp business

The IRS states that to qualify for S corporation status, a corporation must meet the following requirements:

  • Be a domestic corporation
  • Have only allowable shareholders
    • May be individuals, certain trusts, and estates and
    • May not be partnerships, corporations or non-resident alien shareholders
  • Have no more than 100 shareholders
  • Have only one class of stock
  • Not be an ineligible corporation (i.e. certain financial institutions, insurance companies, and domestic international sales corporations).

Understanding the benefits and limitations of forming an S corp for your business is the first step in discovering if this is the entity best suited to your business and tax needs. It is advisable to consult with a CPA that understands the legalities in this regard. At Fusion, our CPAs are equipped to advise new businesses in this regard.
