LLC vs S Corporation: What’s the Difference?
An LLC and an S corporation are not competing business entities in the way most people think—an LLC is a legal structure, while an S corporation is a tax election. The real question is whether you should operate as an LLC with default taxation or elect S corporation status for tax purposes. This guide explains the differences, benefits, and when each option makes sense.
LLC vs S Corporation: The Core Difference
The most important distinction is this:
LLC (Limited Liability Company): A legal business structure created under state law
S Corporation (S Corp): A tax classification you can elect with the IRS
In other words, you don’t choose between an LLC or an S corporation—you typically form an LLC first and then decide how you want it taxed.
What Is an LLC?
An LLC is a flexible business structure that provides liability protection and simple management.
Key Features of an LLC
Protects personal assets from business liabilities
Can have one or multiple owners (members)
Offers pass-through taxation by default
Requires fewer formalities than a corporation
Most small businesses start as LLCs because they are easy to form and operate.

What Is an S Corporation?
An S corporation is a tax election made with the IRS (Form 2553). It changes how your business income is taxed, not how your business is legally structured.
Key Features of an S Corp
Pass-through taxation (no double taxation)
Potential savings on self-employment taxes
Requires owners to take a “reasonable salary”
Has stricter rules and compliance requirements
An LLC or corporation can elect S corp status if it meets IRS requirements.
How Taxes Differ: LLC vs S Corporation
Taxes are the main reason business owners consider S corporation status.
Default LLC Taxation
All profits are subject to self-employment tax
Income passes through to your personal tax return
S Corporation Taxation
Owners must take a reasonable salary (subject to payroll taxes)
Remaining profits may be distributed as dividends (not subject to self-employment tax)
Why This Matters
The S corp election can reduce self-employment taxes—but only when your business income reaches a certain level.
When an LLC Makes More Sense
For many businesses, sticking with default LLC taxation is the best choice.
Choose an LLC If:
You are just starting your business
Your profits are relatively low or inconsistent
You want simplicity and minimal compliance
You don’t want to run payroll
LLCs are ideal for early-stage businesses and solo entrepreneurs.
When an S Corporation Makes More Sense
An S corp election can be beneficial once your business reaches a certain level of profitability.
Consider an S Corp If:
Your business generates consistent net income (often $50,000+ or more)
You are willing to run payroll and handle additional compliance
You want to reduce self-employment taxes
You can justify a reasonable salary
At this stage, the tax savings may outweigh the added complexity.
Pros and Cons of an LLC
Advantages
Simple to form and maintain
Flexible management structure

No payroll requirements (unless you choose)
Disadvantages
All profits subject to self-employment tax

Pros and Cons of an S Corporation
Advantages
Potential tax savings on self-employment taxes
Pass-through taxation
More structured compensation strategy
Disadvantages
Must run payroll
Additional accounting and compliance requirements
IRS scrutiny on “reasonable salary”
More administrative complexity

Common Misconceptions
“An S Corp Is a Type of Business Entity”
Not exactly. It’s a tax status, not a separate legal structure.
“S Corps Always Save Money”
Not always. If your income is too low, the extra costs (payroll, accounting) may outweigh the savings.
“You Have to Start as an S Corp”
No. Most businesses start as LLCs and elect S corp status later if it makes sense.
How to Elect S Corporation Status
If you already have an LLC, you can elect S corp taxation by filing with the IRS.
Basic Steps
Obtain an EIN
File IRS Form 2553
Set up payroll for owner compensation
Timing matters—there are deadlines for making the election.

Common Mistakes to Avoid
Electing S corp status too early
Not paying a reasonable salary
Ignoring additional compliance requirements
Failing to maintain proper records
Choosing based only on tax savings without considering complexity
Avoiding these mistakes helps ensure you actually benefit from the S corp election.

Can an LLC be taxed as an S corporation?
Yes. An LLC can elect S corp taxation by filing with the IRS.
