When your small business starts making consistent profit, someone will eventually tell you to “elect S-Corp status.” It sounds like free money ? and for some businesses, it genuinely saves thousands per year. For others, the savings don’t justify the overhead. This article breaks down the real LLC vs. S-Corp comparison so you can make an informed decision instead of guessing.
What We’re Actually Comparing
A single-member LLC is a legal structure that, by default, is taxed as a sole proprietorship. All profit flows to your personal return on Schedule C, and you pay self-employment (SE) tax of 15.3% on the full net profit (up to the Social Security wage base of $168,600 for 2024, then 2.9% above that).
An S-corporation is a tax election (Form 2553) that changes how that income is taxed. The business files a separate return (Form 1120-S), and you as the owner receive two streams: a W-2 salary and distributions. Self-employment tax only applies to your W-2 wages ? not to distributions. That gap is where the savings come from.
The Tax Math: A Side-by-Side Example
Assume you’re a consultant with $120,000 net profit and you’re in the 22% federal income bracket.
As a Single-Member LLC (Schedule C)
- Net profit: $120,000
- Self-employment tax (15.3% ? $120,000): $18,360
- SE tax deduction (half of SE tax): ?$9,180
- Federal income tax on ~$110,820: ~$24,380
- Total federal tax: ~$42,740
As an S-Corp (Same $120,000 Profit)
- Reasonable salary: $60,000
- Payroll taxes on salary (15.3%): $9,180 (split between you and the company)
- Distribution: $60,000 (no SE tax)
- Federal income tax: similar to LLC after deductions
- Total federal tax: ~$33,560
- Estimated annual savings: ~$9,000
The savings are real ? but so are the added costs.
The S-Corp Overhead You Have to Factor In
Running an S-Corp isn’t free. Add up these annual costs before deciding:
- Payroll processing: $500?$2,400/year (Gusto, QuickBooks Payroll, etc.)
- Separate business tax return (Form 1120-S): $500?$1,500 in additional CPA fees
- State registration/annual reports: varies by state (Florida requires an annual report filing fee)
- Bookkeeping complexity: payroll entries, owner distributions, shareholder basis tracking
If those costs total $3,000?$4,000 per year, your net savings at $120,000 profit are still positive. But if you’re at $60,000 profit, the math often doesn’t work.
The Break-Even Point
The conventional guideline is that an S-Corp election makes financial sense when your business net profit consistently exceeds $50,000?$60,000 per year. Below that, overhead costs eat most of the tax savings. Above $80,000+, the savings accelerate meaningfully.
This is a guideline, not a rule. Your specific industry, state, deductions, and how aggressively you want to minimize SE tax all affect the calculation.
The Reasonable Salary Requirement
The IRS requires S-Corp owner-employees to pay themselves a “reasonable salary” ? compensation comparable to what the market would pay someone doing that job. You cannot set your salary at $1 to avoid all payroll taxes. The IRS actively audits S-Corps with suspiciously low owner salaries.
What’s reasonable? For a bookkeeper: $45,000?$65,000. For a software consultant: $80,000?$120,000. For a dentist: $150,000+. Industry wage surveys and Bureau of Labor Statistics data are useful references.
Other Considerations
Retirement Contributions
S-Corp owners can contribute to a Solo 401(k) or SEP-IRA based on their W-2 compensation. At the same profit level, the S-Corp may allow slightly smaller contributions than a sole proprietor (because the contribution is capped as a percentage of W-2 wages, not total profit). This is a nuance many people miss.
Florida-Specific Note
Florida has no personal income tax, so the LLC vs. S-Corp decision here is purely federal. Some states impose a franchise tax or minimum fee on S-Corps that can erode the savings ? not an issue in Florida, which makes the S-Corp election relatively more attractive for Florida businesses.
Healthcare Deductions
S-Corp owners (greater than 2% shareholders) can deduct health insurance premiums by routing them through payroll ? a process that requires specific handling to get the deduction correctly. It’s an extra bookkeeping step but often worthwhile.
When to Stay as an LLC
- Profit is below $50,000 and likely to stay there
- You want maximum simplicity and minimal paperwork
- Your business is seasonal or unpredictable
- You’re in the first 1?2 years of business
When to Elect S-Corp Status
- Net profit consistently above $60,000 and growing
- You have the bandwidth to handle payroll
- You already work with a bookkeeper and CPA
- You want to maximize retirement contributions through a W-2 salary structure
How to Make the Election
You file IRS Form 2553 to elect S-Corp status. The deadline is March 15 for the current tax year (or within 75 days of forming the entity). If you miss it, you can often request a late election ? but it’s better to plan ahead. In most states, you also need to register with the state as an S-Corp or ensure your LLC operating agreement reflects the election.
