S Corporation (Sub S) Tax Election: A Founder-Friendly Guide to Lowering Your Business Taxes
If you’re a founder running a profitable business, there’s a good chance you’re overpaying taxes without realizing it.
One of the most common — and most misunderstood — opportunities to reduce those taxes is the S Corporation election, often called a Sub S election. Despite the intimidating name, this strategy is not just for large companies or sophisticated finance teams. In fact, it’s most powerful for small to mid-sized founder-led businesses.
This article explains, in simple terms, what a Sub S election is, how it compares to regular LLC taxation, and when it can create meaningful, legitimate tax savings.
What Is an S Corporation (Sub S) Election?
An S Corporation is not a type of business entity — it’s a tax election you make with the IRS.
Most founders operate as:
Single-member LLCs
Multi-member LLCs
Corporations
By default, these structures are typically taxed in one of two ways:
Sole proprietorship (single-member LLC)
Partnership (multi-member LLC)
A Sub S election changes how your profits are taxed, not how your business operates day to day.
Important:
Your legal entity stays the same. You’re simply telling the IRS to tax your income differently.
The Hidden Tax Problem with Regular LLC Taxation
Under default LLC taxation, all business profits are subject to self-employment tax.
Self-employment tax covers:
Social Security (12.4%)
Medicare (2.9%)
That’s a combined 15.3%, applied on top of regular income taxes.
So if your LLC earns $150,000 in profit:
The IRS treats all of it as your personal earned income
You pay self-employment tax on the full amount
This is where many founders unknowingly overpay.
How Sub S Taxation Works (In Plain English)
With a Sub S election, your income is split into two buckets:
Salary
You pay yourself a “reasonable salary”
This portion is subject to payroll taxes
Distributions (Profit)
Remaining profits are paid to you as distributions
These are not subject to self-employment tax
You still pay income tax on both — but you avoid self-employment tax on the distribution portion.
That difference is where the savings come from.

Numerical Example: What the Savings Actually Look Like
Let’s walk through a simplified example.
Scenario: $200,000 Annual Business Profit
Regular LLC Taxation
Entire $200,000 subject to self-employment tax
Self-employment tax ≈ $30,600
Income tax still applies on top
Sub S Taxation
Reasonable salary: $100,000
Payroll taxes on salary ≈ $15,300
Remaining $100,000 paid as distributions
No self-employment tax on distributions
Estimated Annual Tax Savings
👉 Approximately $15,000
As profits increase, the savings generally scale as well — until they plateau based on Social Security wage limits.
When Does a Sub S Election Start to Make Sense?
While every situation is different, a Sub S election often becomes attractive when:
Net business profit exceeds $50,000–$75,000
The business generates consistent income
The founder actively works in the business
You’re comfortable running payroll
Below that range, the administrative cost may outweigh the benefits. Above it, the math often works strongly in your favor.
Who Should Not Choose a Sub S Election?
A Sub S election is not a universal solution. It may not be ideal if:
Your business profits are still inconsistent
You’re in a very early startup phase
The business is largely passive income
You plan to reinvest nearly all profits
State-level taxes reduce the benefit
This is why context matters more than blanket advice.
Common Myths About Sub S Elections
“It’s only for big companies.”
Not true — many solo founders benefit the most.
“It’s aggressive or risky.”
When done correctly, it’s fully legal and widely used.
“I can pay myself almost nothing.”
Incorrect — the IRS requires a reasonable salary.
“My payroll software handles everything.”
Payroll helps, but strategy still matters.
How to Make a Sub S Election (High Level)
To elect S Corporation status, you file IRS Form 2553.
Key points:
Timing matters (deadlines apply)
Late elections may be allowed in some cases
Coordination with payroll and accounting is critical
This is one area where professional guidance can prevent costly mistakes.
Final Thoughts for Founders
A Sub S election isn’t about gaming the system — it’s about aligning your tax structure with how your business actually operates.
For many founders, it’s one of the simplest ways to:
Reduce self-employment taxes
Keep more of what they earn
Create a more intentional compensation strategy
The key is knowing when it fits — and when it doesn’t.
