How Much Does an S-Corp Save in 2026? Four Numbers Decide It

Run the calculator. Get a savings number. Now the real question is whether that number is conservative, accurate, or fantasy. At $400,000 of net profit with a $184,500 salary, a single filer running a non-SSTB business saves about $20,372 a year with an S-Corp election over a sole proprietor. About $8,189 of that is payroll-tax savings. The other $12,182 comes from the QBI deduction, which a wageless sole prop can't claim at this income level. The calculator does the math. This post explains where it comes from.

The savings come from two places: payroll tax and QBI

Ask why an S-Corp saves money and most people give the same answer: self-employment tax. They're not wrong. They're just telling you half the story.

Self-employment tax is 15.3% on net earnings from self-employment, up to the 2026 Social Security wage base of $184,500 (SSA 2026 contribution and benefit base). Above that wage base, the Social Security portion stops. But the 2.9% Medicare portion does not, and single filers above $200,000 owe an extra 0.9% Additional Medicare Tax on top of it. An S-Corp election lets you split profit into a W-2 salary, subject to FICA, and a distribution, which isn't. That's mechanism one..

Mechanism two gets less attention, and at higher income it can matter more than the first. Section 199A lets owners deduct up to 20% of qualified business income (QBI). 

Above the 2026 phase-in range, $201,750 single or $403,500 joint, that deduction gets capped by a wage limitation: the greater of 50% of W-2 wages paid, or 25% of wages plus 2.5% of qualified property. That range is checked against your total household income, not just what the business nets, so a spouse's income or other earnings can push you into the wage limitation even if the business profit alone wouldn't. A sole proprietor with no employees pays $0 in W-2 wages, so the limitation caps their deduction at $0 above that range.

An S-Corp paying a real salary clears the test and unlocks a deduction the sole prop gets none of. Below the phase-in range, though, a sole prop already gets the full deduction with no wage requirement, so there's nothing extra for an S-Corp to unlock there. 

Below that line, payroll tax is the whole story. Above it, for a non-SSTB business (one that isn't a specified service trade or business, like law, accounting, or consulting), both mechanisms stack.

Neither mechanism changes your income tax rate. What changes is how much FICA you owe and how much income the QBI deduction shelters, and both depend on the same input: your W-2 salary. Payroll and QBI are just two pieces of how LLC, S-Corp, and C-Corp taxation actually compares overall. What decides your number here comes down to four inputs, plus the QBI boundary that decides whether the second mechanism applies to you at all.

The four inputs behind your savings

Four things move the number, and not by the same amount.

• Net profit. The bigger the gap between profit and reasonable salary, the more payroll-tax savings you generate. Below $80,000, the math doesn't clear the cost of payroll and a corporate return. $150,000 is where payroll-tax savings start to matter. Once your household income, not just business profit, clears the 2026 QBI phase-out range ($201,750 single, $403,500 joint), a second savings channel opens. A spouse's income can push you across that line even if the business alone wouldn't, which is why the worked example below shows both mechanisms stacking.
• Reasonable salary. The single biggest lever, and the one owners get wrong most. Lower salary means more distribution means more payroll-tax savings. But the IRS reasonable-compensation standard caps how low you can go, based on role, industry, and comparable wages (IRS: Wage Compensation for S Corporation Officers). Above the QBI phase-out range, salary cuts both ways: a higher salary raises FICA cost, but it also raises the wage-limitation ceiling on your QBI deduction. The right number balances both, not just one. The 60/40 rule (60% salary, 40% distribution) is a sanity-check starting point, not a rule the IRS recognizes. Setting a defensible reasonable salary takes more than a rule of thumb.
• State. This is the input the calculator can't capture, and it's the kind of nuance worth a conversation with a tax strategist instead of a slider. Tennessee, for example, taxes S-Corps, C-Corps, and multi-member LLCs at 6.5% of net earnings above a $50,000 exemption (Tennessee Franchise & Excise Tax Manual). A sole proprietor or single-member LLC pays none of it, which makes the tax a real S-Corp-specific cost, not a rounding error. California's 1.5% franchise tax works the same way. Some states offer no payroll-tax advantage at all. The federal number the calculator shows you is half the answer.
• Current entity. If you're a sole proprietor or single-member LLC today, the entire savings calculation is still on the table. If you're already an S-Corp and wondering whether to unwind it, the math runs in reverse, and for owners who elected before profit justified it, the overhead can cost more than the savings are worth.

How much an S-Corp saves at $400K

Here's the comparison at $400,000 of net profit with a $184,500 salary, for a single filer running a non-SSTB business, using 2026 rates.

Of that $20,372, $8,189 is payroll-tax savings, the mechanism explained above. The other $12,182 comes from lower business income tax, driven by the $40,277 QBI deduction the sole prop doesn't get. That's the QBI mechanism in dollars. A wageless sole prop is capped at $0 here, and the S-Corp's real salary clears the wage limitation and unlocks the deduction.

This example assumes a single filer with household income in the $364,201–$464,200 range, a non-SSTB business, and profit past the top of the 2026 QBI phase-out range. Change any of those assumptions, filing status, household income, SSTB classification, or profit under $201,750, and the split between these two numbers changes, sometimes down to payroll tax alone.

For 2026, the full QBI phase-in range is $403,500 to $553,500 for joint filers and $201,750 to $276,750 for single filers (IRS Rev. Proc. 2025-32). Below the bottom of that range, the wage limitation doesn't apply to anyone, sole prop or S-Corp. Above the top, it applies in full, which is the case in the worked example above.

How to read your calculator output

The S-Corp Savings Calculator breaks down into a few things worth understanding on their own, not just a headline number:

• The headline figure. Your total estimated savings, combining payroll tax and the income-tax effect of the QBI deduction, net of an estimated payroll administration cost.
• The QBI deduction line. Shows how much of your total comes from clearing the wage limitation, not from the payroll-tax mechanism at all. Below the phase-out threshold, this line often reads $0 for both structures, and the whole savings figure is payroll tax.
• The recommendation line. A plain verdict, something like "An S-Corp election looks worth it," telling you whether your savings clear the cost of running payroll. That's the tool's version of a breakeven check, not a specific profit figure.
• The salary slider. Where the bulk of your sensitivity lives, now for two reasons. Move that number by $10,000 and watch both the payroll-tax savings and the QBI deduction shift, sometimes in opposite directions.

"The reasonable-salary input decides two numbers at once, your payroll tax and your QBI deduction," says Derek Bungard, CPA, Senior Tax Manager at Visor. "That's a conversation, not a slider."

Four checks before you trust the number

Run these against your own situation before you take the headline figure at face value.

• Your profit sits below the QBI phase-out threshold. Below $201,750 single or $403,500 joint, the wage limitation doesn't apply to anyone. A sole prop already gets the full QBI deduction without paying a dime in wages, so the S-Corp's income-tax edge disappears and the payroll-tax savings are the whole number, not part of a bigger one.
• You're an SSTB above the phase-out range. Law, accounting, financial services, consulting, and medicine lose the QBI deduction above the range instead of having it wage-limited. The deduction you'd expect from a non-SSTB comparison doesn't apply to you.
• Your defensible salary is higher than the calculator's default. If your real comparables (role, industry, hours, region) put your number well above the tool's default, payroll-tax savings compress, even as the higher wage may raise your QBI ceiling. Test it: swap in your real salary and see how the two numbers move.
• Your state taxes S-Corps at the entity level. California's 1.5% franchise tax and Tennessee's 6.5% excise tax (above a $50,000 exemption, and just for S-Corps, C-Corps, and multi-member LLCs, not sole props) erode the federal win, and this is the kind of state-level nuance a tool can't model well. If you haven't reviewed how your state treats the election, a conversation with Visor's tax team covers ground the calculator doesn't.

A strategist-level review of these tradeoffs is the exact conversation that separates a preparer who files your return from someone running the numbers before you elect.

When an S-Corp doesn't save you money

The calculator returns small or negative total savings in three predictable situations:

• Profit under $80,000
• A defensible reasonable salary that consumes most of the profit anyway
• Existing S-Corp owners whose reasonable comp is already set high enough that there's little distribution left to shelter

That's not the calculator failing you. That's the tool doing what it's built to do. The election isn't free. Payroll setup, a separate corporate return, and ongoing quarterly filings all cost real time and real money. As a rule of thumb, if the calculator returns savings in the low four figures, the administrative overhead of running payroll and filing Form 1120-S eats most or all of the benefit.

"The right time to not elect S-Corp is when the calculator says so," notes Mitchell Baldridge, CPA, CFP®, Co-Founder at Visor. "It's a math problem, not an identity."

What to do after the calculator

If the calculator shows material savings and you're not yet an S-Corp, the next step is a real conversation with Visor's team about your actual number, not the calculator's estimate. Visor can help you file Form 2553 and get the paperwork right no matter when in the year you start.

If you're already an S-Corp, the work isn't done. The next step is confirming with Visor's team that your QBI deduction is optimized now, and stays optimized as your profit and salary change. A salary set three years ago doesn't reflect three years of growth, and re-running the numbers is often where savings on both the payroll side and the QBI side are sitting unclaimed.

If the calculator returns modest numbers, that's not the end of the conversation. It means an S-Corp isn't the lever to pull yet, not that there isn't one. Visor's team can verify that call, then go looking for the levers a tool built for one decision was never going to catch: retirement contributions, entity structure, timing moves on the return itself.

A number on a screen doesn't file your election, catch the deductions a calculator can't see, or flag it when your situation changes. A CPA does. That's the conversation to have before you act on any of this.

Frequently asked questions

How much does an S-Corp save in 2026? A $400K-net-profit S-Corp can save five figures a year once two mechanisms stack: payroll-tax savings from splitting salary and distribution, and income-tax savings from unlocking the QBI deduction above the 2026 phase-out range. That range is checked against household income, not business profit alone, so a spouse's income can move you across the line either way. For a single filer with household income above the phase-out threshold running a non-SSTB business, the combination can reach the low five figures. Below the QBI phase-out threshold, $201,750 single or $403,500 joint, just the payroll-tax mechanism applies, and typical savings run smaller, often four figures rather than five. State and reasonable-salary assumptions shift both numbers further.

What's the breakeven income for an S-Corp in 2026? Most CPAs place the practical breakeven somewhere in the $80,000–$100,000 range of net business profit. Below that range, the cost of running payroll, filing a corporate return (Form 1120-S), and administering quarterly payroll taxes tends to erode the self-employment tax savings. The exact breakeven depends on what reasonable salary you'd pay yourself, your state's treatment of S-Corps, and how deep your accountant goes on entity-level deductions. The Visor S-Corp Savings Calculator shows the annual savings, payroll tax difference, and QBI impact for your specific inputs. Use it to test whether the math clears the administrative cost at your profit level.

How is S-Corp salary different from S-Corp distributions for tax purposes? S-Corp salary (W-2 wages paid to the owner) is subject to FICA payroll tax at 15.3%, split between employer and employee, though in practice the owner pays both halves. S-Corp distributions, the profit above the salary, flow through to the owner's personal return and are subject to income tax but not FICA. That difference (15.3% on salary versus 0% FICA on distributions) is the core payroll-tax mechanism. Above the QBI phase-out range, that same salary also sets the wage limitation on your QBI deduction, so the number does double duty.

Will the S-Corp Savings Calculator's number hold up under IRS scrutiny? The math behind the savings number is correct given your inputs. What the IRS scrutinizes is the reasonable-salary input. If it's set too low, the IRS can reclassify distributions as wages and assess back FICA plus penalties (this is what happened in David E. Watson, P.C. v. United States, 668 F.3d 1008, 8th Cir. 2012). Above the QBI phase-out range, that same input also decides your wage limitation, so an indefensible salary puts two numbers on your return at risk, not one. The calculator uses defensible defaults, but the actual reasonable-salary number for your business should be set with a CPA based on comparable wages, role, and the factors the IRS applies.
