TL;DR — The S-Corp question in six points:
1. An LLC and an S-Corp are not opposites — "S-Corp" is a tax election an LLC (or corporation) can make. 2. The savings come from SE tax — you pay 15.3% only on your "reasonable salary," not on profit distributions. 3. The cost is real: ~$1,200–$2,500/year in payroll service + extra tax return + state fees. 4. Breakeven is roughly $50K–$80K of net business income, depending on state fees, payroll cost, bookkeeping complexity, and how defensible your reasonable salary is — below that range, the S-Corp loses money. 5. QBI interaction matters: S-Corp wages reduce your QBI deduction at higher incomes. 6. "Reasonable salary" is the audit risk — pay yourself too little and the IRS will reclassify distributions as wages.
Walk into any freelancer Facebook group or r/freelance thread asking about taxes and within three replies someone will tell you to form an S-Corp. They're often right — but they're often wrong, too, because the math depends on numbers most people don't bother to plug in: your actual net income, your reasonable salary, the cost of compliance, and your QBI eligibility.
This guide walks through the actual math. By the end you should know whether the S-Corp election makes sense for your specific income level, and what you'd need to do operationally if you elect it.
First: What "LLC vs S-Corp" Actually Means
The phrasing is misleading. "LLC" is a legal structure. "S-Corp" is a tax election. They're not in the same category, which is why the comparison gets confusing.
Your business has two separate identities:
- Legal entity: sole proprietor, single-member LLC, multi-member LLC, C-corp, etc. This is what you file with your state.
- Tax classification: sole prop (Schedule C), partnership, S-corp (Form 1120-S), C-corp (Form 1120). This is how the IRS taxes you.
By default, a single-member LLC is taxed as a sole proprietor (Schedule C). That's the most common setup for freelancers. If you elect S-Corp tax treatment (file Form 2553), you keep the LLC legal structure but switch the tax classification.
So the real comparison freelancers should be making is:
- Sole proprietor / default LLC (no election) vs.
- LLC with S-Corp election
Most freelancers don't actually need a C-corp; the structure forces double taxation that almost never benefits an owner-operator. We'll set that aside.
How the Tax Savings Actually Work
The reason an S-Corp can save money is one specific feature of the tax code: properly characterized S-Corp owner distributions are generally not subject to self-employment or FICA tax. (The "properly characterized" qualifier matters — if you under-pay yourself in salary, the IRS can reclassify distributions as wages, which we cover later.)
As a sole prop or default LLC, every dollar of your net business income is hit with 15.3% SE tax (12.4% Social Security on income up to $184,500 in 2026, plus 2.9% Medicare on all of it). On $100,000 of net income, SE tax alone is $14,130.
As an S-Corp, the IRS requires you to pay yourself a "reasonable salary" via W-2 payroll (subject to the same 15.3% in employer + employee FICA). Anything left over after salary is a "distribution" — not wages, not subject to FICA at all. That's the savings vehicle.
| Sole Prop | S-Corp | |
|---|---|---|
| Net business income | $120,000 | $120,000 |
| Reasonable salary (W-2) | — | $60,000 |
| Distribution (no FICA) | — | $60,000 |
| SE tax base / FICA wages | $110,820 (92.35%) | $60,000 |
| SE tax / FICA (15.3%) | $16,955 | $9,180 |
| Tax savings before costs | $7,775 |
The S-Corp saves $7,775 in payroll-type taxes. But that's gross savings — we haven't subtracted the cost of running an S-Corp yet.
The 15.3% framing weakens at higher incomes. The headline savings rate of 15.3% only fully applies below the Social Security wage base ($184,500 in 2026). Above the cap, the Social Security component (12.4%) drops out and only the 2.9% Medicare portion remains on the additional income. And above $200,000 single / $250,000 joint, the 0.9% Additional Medicare Tax applies to earned income (both W-2 wages and SE earnings), narrowing the wage-vs-distribution gap further. For very high earners, S-Corp savings come mostly from avoiding Medicare + Additional Medicare on the distribution portion — still meaningful, but smaller per dollar than the headline SE rate implies.
What an S-Corp Actually Costs You
The savings number above is what every "form an S-Corp!" influencer quotes. Here's what they leave out.
1. Payroll service: $600–$1,500/year
You can't just pay yourself from the business checking account anymore. You need a payroll provider (Gusto, ADP RUN, QuickBooks Payroll, OnPay) that runs scheduled payroll, withholds federal/state/FICA, files quarterly 941s, issues a W-2 in January, and remits payments to the IRS and state. Cheapest reputable option for a single-employee S-Corp is around $50/month. Add state-specific fees and you're looking at $700–$1,500/year.
2. Separate tax return (Form 1120-S): $500–$1,500/year
Your S-Corp files its own federal return (Form 1120-S) plus K-1s to shareholders (you). This is more complex than a Schedule C and most freelancers don't DIY it — you'll pay a CPA or tax preparer $500–$1,500. Higher in CA/NY metros.
3. State franchise/excise/minimum tax: $0–$800/year
Several states impose a flat fee or minimum tax on S-Corps regardless of income:
- California: $800/year minimum franchise tax. Always.
- Tennessee: $100 minimum franchise tax (excise tax is a variable 6.5% of net earnings on top, with no fixed minimum).
- Massachusetts: $456 minimum corporate excise.
- New York: $25–$4,500 sliding fixed-dollar minimum, depending on receipts.
- Texas, Florida, most no-income-tax states: $0.
State treatment isn't always pass-through. A handful of jurisdictions don't fully follow federal S-Corp recognition. New York City, for example, levies its Unincorporated Business Tax (UBT) on single-member LLCs but exempts S-Corps, which can flip the math in NYC's favor. Tennessee taxes S-Corp earnings through its franchise/excise structure regardless of federal pass-through treatment. New Hampshire's Business Profits Tax doesn't recognize S-Corp pass-through at all. Always check your state and local rules before electing — federal SE tax savings can be partially or fully offset by state-level treatment.
4. Bookkeeping and admin overhead: variable
S-Corps require cleaner books than sole props because the IRS scrutinizes them more. You'll want a real bookkeeping system (QuickBooks, Wave, or a bookkeeper). You'll also lose some flexibility — you can't just pull money out of the business at will; distributions need to be tracked and proportional to ownership.
Total annual S-Corp overhead
| Payroll service (Gusto-tier) | $700 |
| S-Corp tax return prep (CPA) | $900 |
| State franchise/minimum tax (e.g., MA) | $456 |
| Bookkeeping software | $240 |
| Total annual cost | $2,296 |
Higher in CA ($800 franchise tax adds on), higher in NYC metro ($1,500+ CPA fees). Lower in TX/FL/WA where there's no state minimum tax.
The Real Breakeven
So when does the S-Corp actually pay off? Roughly: when your gross SE-tax savings exceed your total annual S-Corp overhead.
The math depends on what "reasonable salary" you can defensibly pay yourself. The IRS doesn't publish a fixed rule — "reasonable" means what someone with your skills would earn doing the same work as a W-2 employee. Common rules of thumb:
- 50/50 split (half salary, half distribution) for net income up to ~$200K.
- 60/40 split for higher incomes where reasonable salary would top out around the SS wage base ($184,500 in 2026).
- Specialized professionals (lawyers, doctors, consultants) need to set salary closer to market rates for their profession; aggressive low-balling is the #1 trigger for IRS reclassification.
| Net Business Income | SE Tax Savings (Gross) | Annual S-Corp Cost | Net Benefit |
|---|---|---|---|
| $50,000 | $3,233 | $2,300 | $933 |
| $60,000 | $3,879 | $2,300 | $1,579 |
| $80,000 | $5,172 | $2,300 | $2,872 |
| $100,000 | $6,465 | $2,300 | $4,165 |
| $150,000 | $9,698 | $2,300 | $7,398 |
| $200,000 | $11,628 | $2,300 | $9,328 |
Pure SE tax math, before QBI considerations. Assumes you can defensibly pay yourself a 50% salary — not always realistic for high earners or specialized professionals.
The naive breakeven sits around $50,000–$60,000 of net income. Above that, the S-Corp wins on pure SE tax math; below that, you're paying $2,300/year to save less than $2,300 in SE tax. In practice, real-world breakeven runs $50K–$80K depending on state fees, payroll cost, bookkeeping discipline, and how defensibly you can set your reasonable salary — the high end if you're in California (with its $800 franchise minimum) or paying NYC-metro CPA rates, the low end in a no-state-tax state with cheap payroll and clean books.
But this is before the QBI complication.
The QBI Complication
The Qualified Business Income deduction (now permanent under the OBBBA — see our 2026 OBBBA guide) lets pass-through business owners deduct 20% of qualified business income. For sole props and default LLCs, "qualified business income" is roughly your net Schedule C income. For S-Corps, it's the K-1 distribution — not the W-2 wages you paid yourself.
This sounds neutral, but it isn't. By moving income from Schedule C to W-2, you're shrinking your QBI base. At lower incomes the QBI deduction shrinks dollar-for-dollar with the salary you pay yourself; the savings on SE tax mostly cancel against the lost income tax savings on QBI.
| Sole Prop | S-Corp | |
|---|---|---|
| Net business income | $120,000 | $120,000 |
| QBI base (rough) | $110,820 | $60,000 distribution |
| QBI deduction (20%) | $22,164 | $12,000 |
| Lost QBI deduction | $10,164 | |
| Income tax cost (at 22% bracket) | ~$2,236 | |
| SE tax savings | $7,775 | |
| S-Corp annual overhead | $2,300 | |
| Net S-Corp benefit (after QBI & cost) | ~$3,239 |
Including the QBI shrinkage moves the breakeven up significantly. The naive "$60K breakeven" is closer to $80K–$100K when you account for QBI.
At incomes above the QBI phase-in thresholds ($201,775 single / $403,550 joint in 2026), the calculus shifts again. For "specified service trades" (consulting, law, accounting, health, etc.) above those thresholds, the QBI deduction phases out anyway — so the S-Corp's QBI cost goes to zero and the SE tax savings stand alone. Counterintuitively, very-high-earning consultants often gain more from S-Corp than mid-earning ones.
The wage-limitation reversal for non-SSTBs. For non-specified-service businesses above the same thresholds — product, software, e-commerce, manufacturing, most trades — the QBI deduction is capped at the greater of (a) 50% of W-2 wages paid by the business or (b) 25% of wages plus 2.5% of qualified property. With zero W-2 wages and no qualified property, that ceiling is zero. So above the threshold, paying yourself W-2 wages through an S-Corp can preserve or even expand your allowable QBI deduction rather than shrink it. At very high non-SSTB incomes, the S-Corp election can win on both SE tax savings and QBI eligibility simultaneously — the opposite of the moderate-income dynamic.
The Reasonable Salary Audit Risk
The S-Corp's entire savings depend on you setting your W-2 salary below your total business income. The IRS knows this and watches for owners who aggressively under-salary themselves. A consultant netting $300K who pays themselves $40K is a classic audit profile.
What "reasonable" means:
- Comparable W-2 salary for someone with your experience, doing your kind of work, in your geographic area.
- Defensible against a Glassdoor / BLS salary survey.
- Documented — ideally you've written down the methodology you used to arrive at the salary.
If the IRS reclassifies your distributions as wages, you owe back FICA (15.3%) on the reclassified amount, plus penalties and interest. The savings evaporate quickly. The recent Watson v. Commissioner and similar Tax Court cases have consistently sided with the IRS when owner-officers underpaid themselves dramatically.
The 60% rule of thumb is not law. The "pay yourself 60% of revenue as salary" guidance you've seen on YouTube is industry folklore, not an IRS rule. The actual standard is "reasonable for the work performed." For a software developer in NYC netting $200K, "reasonable" might be $150K (closer to market W-2 salary), which leaves only $50K as distribution and shrinks the S-Corp savings significantly.
Other Costs People Forget
- Solo 401k contribution caps shrink. The "employee" portion of your Solo 401k is capped by your W-2 wages. Pay yourself a $50K salary and your max employee deferral is bounded by that. The "employer" portion (25% of compensation) is also based on salary. S-Corps generally have lower retirement contribution capacity than sole props at the same total income.
- State unemployment insurance (SUTA) and federal (FUTA) on your salary. ~$420/year on the first $7,000 of wages. Small but real.
- Workers' comp insurance. Some states require it even for owner-only S-Corps; others let you opt out via affidavit. Check your state.
- Increased audit attention. S-Corps as a category are audited at higher rates than Schedule C filers. The audit math has gotten worse since the 2024 IRS funding boost.
- Switching back is harder than switching in. Once you elect S-Corp status, reverting to default LLC taxation requires waiting five years (with limited exceptions). Don't elect until you're confident the savings will persist.
When the S-Corp Election Is Almost Always Right
- Net business income consistently above ~$100,000.
- You're already itemizing your bookkeeping (separate business bank account, accounting software, etc.).
- You expect income to stay at or above current level for at least 3–5 years.
- Your work is genuinely a service business where you can defensibly set salary below total revenue (i.e., your skill commands a normal-employee salary that's less than what you actually clear in profit).
- You're in a state with no franchise/minimum tax (TX, FL, NV, WA, WY, SD).
When the S-Corp Election Is Usually Wrong
- Net business income under ~$60,000. The SE tax savings just don't cover the overhead.
- Income is volatile or declining. You'll keep paying S-Corp overhead in low-income years.
- You're in California ($800 franchise tax adds significantly to overhead).
- Your "reasonable salary" would need to be ~80%+ of net income (lawyers, doctors, very-senior consultants doing exactly what they'd do as a W-2 employee).
- You hate paperwork enough that you'll inevitably miss deadlines (late 1120-S = $255/month per shareholder for returns filed in 2026, up from $245).
- You haven't separated business and personal finances yet. Get that infrastructure first.
How to Actually Make the Election
If after running the numbers you decide an S-Corp election makes sense:
- Form an LLC first if you don't have one. (You can also elect S-Corp on a corporation, but LLC + S-Corp election is the standard freelancer structure.)
- Get an EIN from the IRS if you don't have one (free, takes 10 minutes online).
- File Form 2553 to elect S-Corp tax treatment. Must be filed within 2 months and 15 days of the start of the tax year you want it to apply to. Late elections are possible with reasonable cause but require extra paperwork.
- Set up payroll through Gusto / ADP / OnPay before you start paying yourself wages.
- Open separate business accounts if you haven't. The IRS wants to see clean separation between owner and entity.
- Document your reasonable salary methodology. Save the BLS data, Glassdoor screenshots, or salary surveys you used to set your number.
Compare your numbers side by side
IndieCalc's LLC vs S-Corp calculator runs your actual income through both scenarios — including reasonable salary, payroll cost, QBI, and state franchise taxes — and tells you exactly when the election pays off.
Compare LLC vs S-Corp →Common Mistakes
- Electing S-Corp too early. Most freelancers should run as a default LLC for the first 1–2 years until income stabilizes above the breakeven.
- Setting reasonable salary by vibes. Document the basis for your salary number with real comparable wage data.
- Forgetting QBI in the comparison. Free online S-Corp calculators usually ignore QBI entirely, which overstates the S-Corp benefit by thousands at mid incomes.
- Failing to run actual payroll. Some S-Corp owners skip W-2s entirely and treat all draws as distributions. This is a guaranteed audit problem.
- Underestimating the bookkeeping discipline required. S-Corps demand cleaner books than sole props. If you can't keep up, the savings get eaten by accountant cleanup fees.
