What Is an S-Corp, Really?
An S-Corporation is a tax status elected with the IRS, not a type of legal entity you form at the state level. When you incorporate a business, you choose a legal structure — most commonly an LLC, C-Corporation, or in some states, a professional corporation. That legal entity is created by filing with your state.
The "S" in S-Corp refers to Subchapter S of the Internal Revenue Code. It's a federal tax designation that eligible businesses can apply for by filing IRS Form 2553. Once approved, the business is taxed as a pass-through entity — meaning profits and losses flow directly to shareholders' personal tax returns, avoiding the double taxation that applies to C-Corporations.
Who Can Elect S-Corp Status?
To qualify, a business must:
Be a domestic corporation or eligible LLC
Have no more than 100 shareholders
Have only one class of stock
Have shareholders who are U.S. citizens or residents
Both LLCs and C-Corporations can elect S-Corp tax treatment — the legal entity type and the tax status are entirely separate decisions.
Why Does This Matter?
Conflating the two can lead to real problems — from misunderstanding your tax obligations to making incorrect representations on financial documents. Knowing that your LLC can be taxed as an S-Corp (without changing its legal structure) opens up planning opportunities that many business owners overlook.
Understanding your business structure and tax status clearly puts you in a stronger position — whether you're seeking financing, planning for growth, or simply making sure your books reflect reality accurately.
