The LLC vs S-Corp question is the most financially significant decision most freelancers and solopreneurs face — yet it's also one of the most misunderstood. The short answer is that S-Corp election can save you thousands per year, but only above a certain income threshold. Below that threshold, it costs more than it saves.
This guide gives you the real math — including compliance costs that most articles conveniently leave out — so you can make the decision based on actual numbers, not hype. You can also use our LLC vs S-Corp Tax Savings Calculator to get the exact figures for your specific income and state.
The Core Difference: How LLC and S-Corp Are Taxed
First, an important clarification that trips up most people: an LLC is a legal structure, and S-Corp is a tax election. They're not mutually exclusive. The most common setup is a single-member LLC that has elected S-Corp tax treatment.
How a regular LLC is taxed
By default, a single-member LLC is taxed as a sole proprietor. All of your net business income flows to your personal tax return as self-employment income. You pay:
- Self-employment (SE) tax: 15.3% on the first $184,500 of net income (2026 rate), then 2.9% above that
- Federal income tax: Based on your total taxable income and filing status
- State income tax: Varies by state
On $100,000 of net income, your SE tax alone is roughly $14,130 — before income tax.
How S-Corp changes the equation
When you elect S-Corp tax treatment for your LLC, you split your business income into two categories:
- W-2 salary — paid to yourself as an employee, subject to payroll taxes
- Owner distributions — the remaining profit taken as distributions, which are not subject to self-employment or payroll tax
The savings come entirely from that distribution portion. On the same $100,000 net income, if you pay yourself a $60,000 salary, you only pay payroll taxes on $60,000 — saving roughly $6,120 compared to the LLC default.
The Real Savings Calculation (Including What Most Articles Skip)
Here's where most LLC vs S-Corp comparisons mislead you: they show gross tax savings without mentioning the compliance costs that S-Corp requires. Those costs are real and significant.
| Net Income | Gross SE Tax Savings | S-Corp Compliance Costs | Net Annual Savings |
|---|---|---|---|
| $50,000 | ~$2,100 | $2,500–$4,000 | Negative |
| $70,000 | ~$3,700 | $2,500–$4,000 | Marginal |
| $90,000 | ~$5,500 | $2,500–$4,000 | +$1,500–$3,000 |
| $120,000 | ~$8,400 | $2,500–$4,000 | +$4,400–$5,900 |
| $160,000 | ~$11,500 | $3,000–$5,000 | +$6,500–$8,500 |
What S-Corp compliance actually costs
- Payroll software (Gusto, Rippling): $600–$1,200/year
- S-Corp tax return (Form 1120-S, filed by a CPA): $800–$2,000/year
- State-level S-Corp fees: $0 in most states; $800 minimum in California; additional fees in New York
- Additional bookkeeping complexity: $0–$1,500/year depending on setup
Total annual overhead: typically $2,500–$4,500 for most single-state solopreneurs.
The Break-Even Point: When Does S-Corp Actually Pay Off?
The general rule used by most CPAs: S-Corp election makes financial sense when your net self-employment income consistently exceeds $70,000–$80,000 per year. Below that, the compliance costs typically eat up the savings or exceed them entirely.
This break-even point varies based on:
- Your state — California's $800 minimum franchise tax raises the break-even significantly
- Your CPA's fees — some CPAs charge $1,500 for an S-Corp return; others charge $3,000
- Your salary split — a higher salary reduces savings; a lower salary increases audit risk
Use our LLC vs S-Corp Calculator to find your specific break-even point with your state, income, and CPA cost factored in.
The Reasonable Salary Rule — The Most Important Variable
The IRS requires S-Corp owner-employees to pay themselves a "reasonable salary" — meaning what you would pay a third-party employee to do the same work. This is both the most important variable in the calculation and the most commonly misunderstood.
Setting your salary too low
The temptation is to set your salary as low as possible to maximize distributions (and therefore tax savings). The IRS knows this temptation exists and actively scrutinizes S-Corp returns where the owner's salary seems artificially low. Getting caught means back payroll taxes, interest, and penalties — potentially wiping out years of savings.
Setting your salary too high
A salary close to your total net income leaves almost nothing for distributions — the whole point of S-Corp. At 90%+ salary, the savings disappear entirely and you're just adding administrative overhead for no benefit.
The practical range
Most CPAs recommend setting your salary at 40–60% of net profit as a starting framework, cross-referenced against Bureau of Labor Statistics wage data for your role and region. The key is having a documented, defensible rationale — not just a number that feels right.
State-by-State Considerations
Federal S-Corp savings are consistent regardless of state. But state-level treatment varies significantly:
Model A — No state income tax states (TX, FL, NV, WA, WY)
The cleanest scenario. Your S-Corp savings are purely federal. No additional state complexity.
Model B — Flat/low tax rate states (AZ, IN, CO, NC, PA)
Simple, predictable. A flat rate on net income regardless of amount. S-Corp still makes sense at the federal break-even point.
Model C — Progressive tax states (NY, OR, NJ, MN)
More complex, but S-Corp still generally makes sense. The higher your income, the higher the effective state rate — which can actually increase the benefit of S-Corp in some high-income scenarios.
Model D — California
The unique case. California imposes a 1.5% franchise tax on S-Corp net income, with an $800 minimum. At $100,000 net income, that's $1,500 in additional state cost. At lower incomes where the $800 minimum applies, it can make S-Corp math much tighter. California residents should run the numbers carefully before electing — the federal savings often still exceed the California cost, but the break-even point is higher than in other states.
How to Actually Elect S-Corp Status
S-Corp election is made by filing IRS Form 2553. Key points:
- Deadline for current-year election: March 15 of the tax year (for existing LLCs) or within 2 months and 15 days of formation (for new LLCs)
- Late election relief: The IRS frequently grants relief for late elections if you can show reasonable cause. Missing the deadline doesn't necessarily mean waiting until next year.
- What you need first: An existing LLC in good standing, an EIN, and a CPA who handles S-Corp clients
- Cost to file Form 2553: Free — you file it directly with the IRS at no cost
S-Corp vs LLC: Side-by-Side Comparison
| LLC (Default) | LLC + S-Corp Election | |
|---|---|---|
| SE/Payroll tax on | All net income | Salary portion only |
| Annual tax savings | — | $0–$15,000+ depending on income |
| Required payroll | No | Yes — must run W-2 payroll for yourself |
| Tax returns required | Schedule C on personal return | Form 1120-S (separate business return) + personal return |
| CPA complexity | Low | Moderate to high — not all preparers handle S-Corp |
| Annual overhead | $0–$500 | $2,500–$4,500+ |
| Makes sense when | Income below ~$70k net | Income above ~$70k–$80k net |
Calculate Your Exact Savings

Our LLC vs S-Corp Tax Savings Calculator inputs all of these variables and shows you the exact net savings — including a dynamic green/yellow/red indicator for whether S-Corp makes sense at your income level right now.
Frequently Asked Questions
Can I switch back from S-Corp to a regular LLC?
Yes, but with a significant catch: once you revoke S-Corp election, you cannot re-elect S-Corp status for five years without IRS approval. This is a real constraint that makes it worth getting the decision right the first time rather than treating it as reversible.
Do I need a new EIN when I elect S-Corp?
No. Your existing LLC EIN carries over to S-Corp election. The election changes your tax treatment, not your legal entity. Your EIN stays the same for your Form 1120-S filing and payroll tax deposits.
Can a single-member LLC elect S-Corp status?
Yes — this is the most common setup for solopreneurs. A single-member LLC files Form 2553 to elect S-Corp treatment, then runs payroll for the owner-employee (themselves) and takes remaining profit as distributions. The LLC legal structure stays intact; only the tax treatment changes.
What happens if I elect S-Corp and my income drops?
If your income drops below the break-even threshold in a given year, you'll pay more in compliance overhead than you save. This is one reason CPAs recommend only electing S-Corp when your income is consistently — not just occasionally — above the threshold. Volatile income is a reason to delay the election.
How do I find a CPA who handles S-Corp returns?
Ask specifically: "Do you file Form 1120-S for clients?" and "How many S-Corp clients do you currently serve?" A generalist tax preparer may not be equipped for this. Expect to pay $800–$2,500 per year for a CPA with S-Corp experience — this cost is deductible as a business expense and is factored in
