LLC vs S-Corp: Which Structure Saves You More in Taxes?

Choosing the right business structure is one of the most important financial decisions you'll make as a small business owner. The difference between an LLC and an S-Corp can mean thousands of dollars in your pocket — or handed over to the IRS. Here's a clear breakdown.

What Is an LLC?

A Limited Liability Company (LLC) is a flexible legal structure that protects your personal assets from business liabilities. By default, a single-member LLC is taxed as a sole proprietorship — all profits pass through to your personal return and are subject to self-employment tax (15.3%) on the full net income.

What Is an S-Corp?

An S-Corporation is a tax election (not a separate legal entity) that changes how your business income is taxed. With an S-Corp, you split your income into two buckets:

• Reasonable salary: Subject to payroll taxes (Social Security & Medicare)
• Distributions: NOT subject to self-employment tax

This split is where the savings come from.

The Tax Savings Example

Let's say your business earns $120,000 net profit:

• As an LLC (default): You pay 15.3% SE tax on the full $120,000 = ~$18,360 in SE taxes
• As an S-Corp: You pay yourself a $60,000 salary (SE tax on this = ~$9,180) and take $60,000 as a distribution (no SE tax) = ~$9,180 total SE taxes

When Does an S-Corp Make Sense?

An S-Corp election generally makes sense when your net profit consistently exceeds $40,000–$50,000/year. Below that threshold, the additional administrative costs (payroll, bookkeeping, separate tax return) may outweigh the savings.

• Net profit over $50,000/year ✓
• Stable, predictable income ✓
• Willing to run payroll and maintain records ✓

The Hidden Costs of an S-Corp

Before making the switch, be aware of the added responsibilities:

• You must run formal payroll and pay yourself a "reasonable salary"
• File a separate S-Corp tax return (Form 1120-S) — additional cost
• Quarterly payroll tax deposits and filings
• Some states have additional franchise taxes or fees for S-Corps

LLC Advantages Worth Keeping in Mind

• Simpler administration — no payroll required
• More flexibility in profit distributions
• Lower compliance costs
• Easier to manage for part-time or early-stage businesses

Can You Have Both?

Yes — and many business owners do. You can form an LLC for legal protection and then elect S-Corp tax treatment by filing Form 2553 with the IRS. This gives you the liability protection of an LLC with the tax advantages of an S-Corp.
