Choosing between an LLC and an S-Corporation is one of the most important early decisions a small business owner will make. The structure you pick affects your taxes, payroll requirements, ability to deduct expenses, and even whether the IRS views your activity as a business or a hobby.
Since 2009, we’ve helped thousands of Georgia entrepreneurs choose the right entity — and the truth is simpler than most people think:
If your business earns at least $25,000 in annual profit, it’s usually time to consider switching from a standard LLC to an S-Corp.
This article breaks down the basics in plain English, including a full tax comparison using a $100,000 example.
1. LLC Taxation Basics (Default Schedule C)
When you form an LLC, the IRS treats you as a sole proprietor unless you elect otherwise. That means:
- You report income on Schedule C
- You pay income tax on your profit
- You pay self-employment tax on the entire profit
Self-employment tax (SE tax) covers Social Security and Medicare:
- 12.4% Social Security (up to the annual limit)
- 2.9% Medicare
- + 0.9% Additional Medicare Tax for high earners
Total base SE tax rate: 15.3%
2. S-Corp Taxation Basics
An S-Corporation allows you to split your income into two parts:
- W-2 salary – subject to payroll taxes
- Owner distributions (K-1) – not subject to self-employment tax
This structure exists for one reason: to prevent business owners from paying Social Security and Medicare taxes on more income than necessary — as long as the salary is “reasonable.”
3. The Recommended Profit Threshold: $25,000
We tell Georgia small business owners this:
If your business earns at least $25,000 in annual profit, it’s time to consider an S-Corp.
Below that amount, the administrative cost and payroll requirements usually aren’t worth it.
Above that amount, tax savings typically outweigh the costs.
4. $100,000 Example: LLC vs S-Corp (Advanced, Accurate Breakdown)
Let’s compare a business owner earning $100,000 in profit under two scenarios:
Scenario 1: LLC (Schedule C Sole Proprietor)
- Business profit: $100,000
- Self-employment tax (15.3%): $15,300
- Additional Medicare Tax (if applicable): small increase above thresholds
Total SE tax: $15,300+
And remember — this is in addition to income tax.
Scenario 2: S-Corp (with a $25,000 Salary and $75,000 Distribution)
Let’s assume the owner pays:
- $25,000 W-2 payroll (reasonable for many small service businesses)
- $75,000 distribution
Payroll taxes apply only to the salary portion.
Payroll Tax Breakdown:
- Employee Social Security (6.2% of $25k): $1,550
- Employer Social Security (6.2% of $25k): $1,550
- Employee Medicare (1.45% of $25k): $362.50
- Employer Medicare (1.45% of $25k): $362.50
Total payroll taxes: $3,825
Compared to $15,300+ as an LLC, that’s a tax savings of:
≈ $11,475 per year in SE tax savings
Income tax is generally the same in both structures, but the savings on payroll taxes is where the S-Corp advantage shows up.
This is why the $25,000 profit threshold matters — the savings usually outweigh the administrative cost.
5. What an S-Corp Requires (Most People Overlook This)
Electing S-Corp status does come with extra compliance requirements.
You must complete:
Quarterly Payroll Filings
- 941 quarterly payroll tax returns
- State withholding filings (Georgia DOL + DOR)
- Employer unemployment filings
Annual Filings
- W-2 + W-3 for the owner
- 1099-NECs if required
- 940 annual unemployment return
- 1120-S business tax return
- Schedule K-1 for the owner
These are not optional.
The IRS takes S-Corp compliance seriously.
6. A Note About the “Hobby Loss Rule” (Schedule C Risk)
LLCs taxed as sole proprietorships face the Hobby Loss Rule if they show losses too often.
The IRS expects a legitimate business to show a profit in at least:
3 out of 5 years
S-Corps can still be scrutinized, but the IRS tends to treat them as more formal operations — especially when payroll is properly handled.
7. Summary: When to Choose LLC vs S-Corp
| LLC (Schedule C) | S-Corp |
|---|---|
| Best for very new or low-profit operations | Best when profits exceed $25,000 |
| Simple filing | Requires payroll + 1120-S return |
| Pay SE tax on 100% of profit | Pay payroll tax only on salary |
| Higher audit risk for repeated losses | More formal structure improves credibility |
If your profit is above $25,000, S-Corp status almost always deserves a closer look.
