LLC vs S Corp: Calculate Which Saves You More on Taxes (Real Numbers)

I spent three years as an LLC owner overpaying taxes. Nobody told me that S Corp election could save me $4,200 annually. I found out by accident when my accountant mentioned it during tax prep.

Most business owners pick their structure based on hearsay. Your buddy swears by his LLC. Your cousin says S Corps are complicated. Neither did the math.

Here's how to calculate which structure saves you real money.

The Self-Employment Tax Problem

LLCs get crushed by self-employment tax. You pay 15.3% on every dollar of profit. No exceptions.

Make $100,000 profit as an LLC? You owe $15,300 in self-employment tax alone. Before income tax.

S Corps play by different rules. They split your earnings into salary (subject to payroll tax) and distributions (not subject to self-employment tax).

Same $100,000 profit as an S Corp with a $60,000 salary? You pay payroll tax on $60,000 and zero self-employment tax on the remaining $40,000 distribution.

That's $6,120 in savings right there.

Real Example: Sarah the Consultant

Sarah runs a marketing consultancy. She made $120,000 profit last year as an LLC.

Her tax bill:

• Self-employment tax: $120,000 × 15.3% = $18,360
• Income tax (24% bracket): $120,000 × 24% = $28,800
• Total: $47,160

Same profit as an S Corp with $70,000 salary:

• Payroll tax: $70,000 × 15.3% = $10,710
• Income tax on salary: $70,000 × 24% = $16,800
• Income tax on $50,000 distribution: $50,000 × 24% = $12,000
• Total: $39,510

Sarah saves $7,650 annually by electing S Corp status. That's real money.

The S Corp Salary Requirement

The IRS requires S Corp owners who work in the business to take "reasonable compensation." You can't pay yourself $30,000 when comparable employees earn $80,000.

This requirement limits your tax savings. Higher required salary means less money left for tax-free distributions.

A web developer might need a $75,000 salary based on market rates. A consultant might justify $60,000. The IRS scrutinizes unreasonably low salaries.

When LLCs Win

S Corps aren't always better. They cost more to run and have strict rules.

LLCs win when:

• Your profit is under $60,000 annually
• You have multiple owners with different profit shares
• You want operational simplicity
• Your state has high S Corp fees

California charges S Corps a minimum $800 franchise tax plus 1.5% gross receipts tax. That wipes out tax savings for smaller businesses.

Real Example: Mike the Freelancer

Mike earns $45,000 annually as a freelance writer. He operates as an LLC.

His taxes:

• Self-employment tax: $45,000 × 15.3% = $6,885
• Income tax (12% bracket): $45,000 × 12% = $5,400
• Total: $12,285

As an S Corp, Mike needs a reasonable salary. Let's say $35,000 for a freelance writer.

S Corp taxes:

• Payroll tax: $35,000 × 15.3% = $5,355
• Income tax on salary: $35,000 × 12% = $4,200
• Income tax on $10,000 distribution: $10,000 × 12% = $1,200
• S Corp setup/maintenance costs: $1,500 annually
• Total: $12,255

Mike saves $30. Not worth the complexity.

The Breakeven Calculation

Find your breakeven point with this formula:

(Profit - Required Salary) × 15.3% = S Corp Annual Costs

For most businesses, S Corp annual costs run $1,500 to $3,000. This includes:

• State filing fees
• Payroll processing
• Additional tax prep costs
• Extra accounting complexity

If S Corp costs average $2,000, your breakeven calculation: (Profit - Required Salary) × 15.3% = $2,000

Solve for profit: Profit = ($2,000 ÷ 15.3%) + Required Salary Profit = $13,072 + Required Salary

With a $50,000 required salary, you break even at $63,072 profit.

State Considerations Matter

Some states love S Corps. Others punish them.

Texas has no state income tax. S Corps save the full 15.3% on distributions.

New York charges S Corps additional fees and has complex tax rules. The savings shrink.

California's 1.5% gross receipts tax can eliminate benefits entirely. A business with $500,000 gross receipts pays $7,500 minimum, regardless of profit.

Research your state's specific rules before deciding.

The Hidden S Corp Costs

S Corps require:

• Monthly or quarterly payroll runs (even for yourself)
• Payroll tax deposits and filings
• More complex tax returns
• Corporate formalities like board meetings

These add $1,500 to $4,000 annually in professional fees for most small businesses.

Factor these costs into your calculations. Saving $3,000 on self-employment tax but spending $4,000 on compliance creates a net loss.

Making the Switch

You can elect S Corp status anytime, but timing matters. Make the election by March 15th to apply it to the current tax year.

Miss the deadline? Your election applies to next year's taxes.

Some business owners operate as LLCs but elect S Corp tax treatment. This gives you the operational flexibility of an LLC with S Corp tax benefits.

Run Your Own Numbers

Generic advice doesn't work. Your profit level, required salary, state taxes, and compliance costs create a unique calculation.

Use our income tax calculator to model both scenarios with your actual numbers. Input your expected profit, estimate your required salary, and factor in your state's rules.

The difference might surprise you. I wish I had run these numbers three years ago instead of assuming my LLC was optimal.

Your business structure affects every dollar you earn. Make the choice based on math, not assumptions.
