An S Corporation is not a business entity.
It is a tax election made with the IRS.
What an S Corporation Actually Is
An S Corporation (S-Corp) is a federal tax classification under Subchapter S of the Internal Revenue Code.
It is not:
A legal entity type
A business structure you form with the Secretary of State
A separate type of LLC
What It Really Means
You first form a legal entity:
LLC (Limited Liability Company)
Corporation (Inc.)
Then, that entity can elect to be taxed as an S Corporation by filing IRS Form 2553.
Once approved, the IRS taxes the business under S-Corp rules.
Why People Choose the S-Corp Election
The main reason is tax strategy, specifically:
Reducing self-employment taxes
Splitting income between:
Reasonable salary (W-2 payroll)
Distributions (not subject to SE tax)
How It Works in Simple Terms
Without S-Corp election:
An LLC is taxed by default as a sole proprietorship (single member) or partnership (multi-member).
All net profit is subject to self-employment tax (15.3%).
With S-Corp election:
Owner must run payroll and pay themselves a reasonable salary.
Remaining profit can be taken as distributions, which are not subject to self-employment tax.
You still pay:
Income tax on all profit
Payroll taxes on salary
But you potentially reduce SE tax exposure
Key Takeaway
An S Corporation is:
A tax election that an LLC or corporation adopts for federal tax purposes.
It changes how the business is taxed, not what the business legally is.
