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:

1. Salary

   • You pay yourself a “reasonable salary”

   • This portion is subject to payroll taxes

2. 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.
