An S-Corp election doesn't reduce your tax bill. It reduces the portion of your profit that self-employment tax applies to — and most freelancers who look this up online stop at the first number without ever pricing the second.
The number everyone shows you
Self-employment tax is 15.3% — 12.4% Social Security (capped at $184,500 of net earnings for 2026) plus 2.9% Medicare (uncapped) — applied to 92.35% of your net profit. On $120,000 of net Schedule C profit, that's roughly $16,950. As an S-Corp, you'd only owe payroll tax (the same 15.3%, split employer/employee, but functionally the same cost to you as the sole owner) on your salary, not on the whole $120,000. Pay yourself $70,000 and take the remaining $50,000 as a distribution, and the distribution owes no SE or payroll tax at all — a real, legal savings of roughly $7,650.
That's the part every article covers. It's also only half the calculation.
The number that decides whether it's actually worth it
"Reasonable salary" is not a number you pick — it's a number the IRS can challenge, and the standard is what someone doing your job would be paid in the open market. Pay yourself $30,000 while taking $90,000 in distributions from a business that depends entirely on your own labor, and you haven't found a loophole — you've built an audit target. The IRS has actually litigated this, and courts have sided with reclassifying distributions as wages when the salary looked designed to avoid payroll tax rather than reflect real market pay.
So the real question isn't "can I save money with an S-Corp" — it's "is the gap between my profit and a defensible salary big enough to be worth the cost of running one?" And running one has real costs that the savings number never mentions:
- Payroll processing, typically $50–$100 a month, all year, because an S-Corp owner-employee has to run actual payroll, not just write themselves a check
- A separate business tax return (Form 1120-S), which most people pay a preparer for — commonly $800–$1,500
- State-level costs that vary enormously — some states charge an S-Corp franchise tax or extra filing fee that eats into the savings before you see it
On $120,000 of profit with a genuinely defensible $70,000 salary, the math above nets out positive. On $60,000 of profit, there often isn't enough room between a reasonable salary and the total profit to clear the added costs at all — and a salary that low relative to the work being done is exactly the kind of ratio that draws scrutiny in the first place.
Who this is actually for
Sole proprietors and single-member LLCs with consistent profit clearly above what a reasonable salary for the work would be — typically somewhere north of $80,000–$100,000 in practice, though the honest answer is "whatever your specific defensible salary and cost numbers say," not a round number from a blog post. If your income moves up and down a lot year to year, the compliance cost of running payroll in a lean year can outweigh the whole benefit — this decision doesn't reverse for free once made (revoking an S-Corp election has its own five-year lockout rule).
Where to check your own numbers
The S-Corp Readiness Assessment runs your actual income, a salary you enter, payroll and filing costs, and your state through this exact calculation — not a savings estimate that stops at the first number, but the readiness question: does your specific gap clear your specific costs, and does your salary look defensible enough to survive a look. If you're deciding whether the salary split itself makes sense once you've already elected, LLC vs S-Corp: Which Saves More Tax in 2026 walks through the comparison side by side.
Frequently Asked Questions
Is there a minimum profit required to elect S-Corp status?
No fixed legal minimum, but there's a practical one: the gap between your profit and a reasonable salary has to be large enough to clear payroll processing, a separate tax return, and any state-level costs — and still leave real savings. Below roughly $80,000–$100,000 of consistent profit, that gap is often too thin.
Who decides what a "reasonable" salary is?
There's no fixed formula — the IRS and courts look at what comparable work pays in the open market, factoring in your role, hours, and industry. A defensible number is closer to "what would it cost to hire someone to do exactly what you do" than a percentage of profit.
Can I switch back if it doesn't work out?
Yes, but not immediately — revoking an S-Corp election generally locks you out of re-electing it for five years. That's a real reason to run the numbers on a full year of realistic income before filing, not after a strong first quarter.
