How Much Does an S-Corp Actually Save You? (2026)

← Back to Blog

It's the question behind every S-Corp decision: how much will this actually save me? The honest answer is "it depends on your profit" — but the mechanism is consistent, the math is knowable, and for most owners earning six figures the number is large enough to matter every single year.

This guide walks through where S-Corp savings come from, a worked example with real numbers, the costs you should weigh against them, and how to estimate your own figure. If you'd rather skip straight to a number, our free S-Corp tax savings calculator on the homepage will estimate it in about a minute.

Where the Savings Actually Come From

As a sole proprietor or single-member LLC, essentially all of your net profit is subject to self-employment tax — 15.3% (12.4% Social Security up to the annual wage base, around $184,500 for 2026, plus 2.9% Medicare with no cap). That's on top of your regular income tax.

When you elect S-Corp status, you split your income into two parts: a reasonable salary that runs through payroll, and distributions that you take as an owner. Payroll taxes apply to the salary — but not to the distributions. That gap is the heart of the savings. (Getting the salary right is the whole game; we cover it in how to set a reasonable S-Corp salary.)

The catch — and it's a real one — is that the salary has to be reasonable for your role and industry. Paying yourself an artificially low salary to dodge payroll tax is a classic audit trigger. Done correctly, though, the distribution portion legitimately escapes the 15.3%, and that's money you keep.

A Worked Example

Say you're a consultant with $200,000 of net profit and you set a defensible $80,000 reasonable salary. Rough numbers, framed as an estimate:

• As a sole proprietor: self-employment tax on ~$184,700 of net earnings comes to roughly $28,200.
• As an S-Corp: payroll tax applies only to the $80,000 salary — about $12,200. The remaining $120,000 in distributions isn't hit with the 15.3%.
• Estimated self-employment-tax savings: around $16,000 a year.

A couple of honest caveats. Part of these taxes is itself deductible, so the true net benefit is a bit lower than the headline gap — our calculator accounts for that detail. And the figure scales with profit: at $150,000 the savings are smaller, at $400,000 they're larger. The point isn't the exact dollar amount; it's that the savings are structural and repeat every year you operate this way. For a fuller look at the break-even, see how much it costs to set up an S-Corp and when it makes sense.

The Savings Don't Stop at Self-Employment Tax

Self-employment tax is the biggest and most reliable piece, but it's not the only one. A properly run S-Corp is the foundation for strategies that are awkward or impossible to use as a sole proprietor:

• Solo 401(k) — you can contribute as the employee and have the business contribute on top of your W-2 wages, shifting tens of thousands into tax-advantaged retirement. (More in financial planning & retirement.)
• Accountable plan — reimburse yourself, tax-free, for the business use of your home, phone, and vehicle.
• Augusta rule — rent your home to your business for up to 14 days a year, tax-free.
• Hiring family — shift income to your children at their lower bracket for legitimate work.
• HSA contributions — a triple-tax-advantaged account if you have a qualifying health plan.

Layered on top of the self-employment-tax savings, these are what turn a "nice to have" into a meaningful annual number. Our calculator models each of them so you can see how they stack for your income.

What to Subtract: The Cost of Running an S-Corp

An honest savings estimate nets out the costs. An S-Corp adds real obligations: running payroll, keeping monthly books, filing a separate business return (Form 1120-S), and maintaining the discipline of a reasonable salary and clean records. Handle it yourself and it's mostly time; hire it out and it's a few thousand dollars a year.

That's exactly why there's an income floor. Below roughly $80,000–$100,000 of net profit, those costs can swallow the savings. Above it — and especially in the $150,000+ range we focus on — the savings comfortably outrun the cost, usually several times over.

When Does an S-Corp Pay Off?

A simple way to think about it: the S-Corp starts making sense once your net profit is high enough that the self-employment-tax savings on your distributions exceed the cost of running the structure. For most owners that's around $80,000–$100,000 of profit; the higher you go, the more lopsided the math becomes in your favor. If you're still weighing whether it fits at all, start with S-Corp basics explained or, if you already have an LLC, converting an LLC to an S-Corp.

See Your Own Number

General rules only get you so far — the real answer depends on your profit, your salary, your state, and your filing status. The fastest way to a realistic estimate is to run your own figures: our S-Corp tax savings calculator takes your income, state, and a few inputs and estimates your annual savings, including the layered strategies above. From there, a short call turns the estimate into an exact plan.

Frequently Asked Questions

How much does an S-Corp save on taxes?

It depends on your net profit. The core savings come from self-employment tax: an S-Corp pays payroll tax only on your reasonable salary, not on the distributions on top of it. As an illustration, an owner with $200,000 of net profit and an $80,000 salary might save roughly $16,000 a year in self-employment tax alone — before layered strategies like a Solo 401(k). Your actual number depends on your profit, salary, and state.

At what income does an S-Corp make financial sense?

A common rule of thumb is around $80,000–$100,000 of net profit, because below that the payroll, bookkeeping, and tax-return costs can eat up the savings. Owners earning $150,000 and up typically see the largest net benefit — which is who we focus on.

Do S-Corp savings come only from self-employment tax?

No. Self-employment tax is the biggest and most reliable piece, but a properly run S-Corp also enables a Solo 401(k) with an employer contribution, an accountable plan, the Augusta rule, hiring family, and HSA contributions. These stack on top of the self-employment-tax savings.

What costs offset the savings of an S-Corp?

Payroll processing, monthly bookkeeping, a separate business tax return (Form 1120-S), and the discipline of a defensible reasonable salary. For most owners those run a few thousand dollars a year — well below the tax savings once profit clears roughly $80,000–$100,000.

Is the S-Corp tax savings calculator accurate?

It's a solid estimate, not a guarantee. It uses 2026 federal brackets and estimated state rates and models the main strategies, but your real result depends on your salary, state, filing status, and circumstances. We confirm the exact number in a consultation before you commit to anything.
