S-Corp 60/40 Rule Is a Myth — What IRS Looks At

Part of WageProof's complete guide to S-corp reasonable compensation.

The 60/40 rule is not an IRS rule. There is no revenue ruling, regulation, court opinion, or statute that establishes a 60/40 (or 70/30, 50/50, or any other) salary-to-distribution ratio as a safe harbor for S-corp reasonable compensation. The governing standard is a facts-and-circumstances analysis under Treas. Reg. §1.162-7, which defines reasonable compensation as "such amount as would ordinarily be paid for like services by like enterprises under like circumstances" — a market-value test, not a percentage of profits. Relying on a formula instead can actively hurt you in an audit.

If you've looked into how to set your S-corp salary, you've probably come across the "60/40 rule": pay yourself 60% of net profits as salary, take 40% as distributions. It sounds clean and reasonable. It has no basis in IRS guidance, Tax Court precedent, or any statute.

Where Did the 60/40 Rule Come From?

There is no authoritative source. No IRS document, revenue ruling, court opinion, or legislative history establishes a 60/40 or 50/50 salary-to-distribution ratio as a safe harbor. It appears to be an unsourced industry rule of thumb — passed around through CPA shorthand, payroll-company marketing, and articles in outlets like Entrepreneur and Forbes that have suggested compensation shouldn't exceed half of what an owner takes out of the business. It survives because it scratches a real itch: people want a simple answer to a complicated question. But "easy to apply" and "defensible in an audit" are not the same thing.

What's remarkable is how widely it's repeated by sources you'd expect to know better. ADP, the largest payroll processor in the country, describes the 60/40 rule in its S-corp guidance — while stating plainly that "it's not officially approved by the IRS." Block Advisors mentions the 60/40 guideline with the same caveat: the IRS does not set it, and it shouldn't be the only factor. The popularity isn't limited to marketing copy. In a 2020 RCReports survey of 4,541 CPAs, EAs, and other tax professionals, respondents were asked which methods of determining reasonable compensation the IRS recognizes — with options including the "50/50 Rule," the "Industry Rule," and a "Safe Harbor Rule." The correct answer was "none of the above." 77% got it wrong. Only 23% passed.

So when you read that the 60/40 rule is "what accountants use," that's true — and it's also why so many returns are exposed. Widespread belief in a rule of thumb is not the same as the rule being valid.

Why Does the IRS Reject the 60/40 Rule?

Courts evaluate reasonable compensation under a multi-factor, facts-and-circumstances test. The framework traces back to Mayson Mfg. Co. v. Commissioner, 178 F.2d 115 (6th Cir. 1949), one of the first appellate decisions to lay out a list of factors — qualifications, the nature and scope of the work, the size and complexity of the business, prevailing rates for comparable positions, economic conditions, and others — with no single factor controlling. The IRS's own taxpayer guidance, Fact Sheet FS-2008-25, "Wage Compensation for S Corporation Officers," restates this approach and explicitly lists "the use of a formula to determine compensation" as one of the factors it weighs. Tellingly, the fact sheet also concedes there are no specific guidelines for reasonable compensation in the Code or the regulations — which is exactly why a tidy percentage rule cannot be hiding in the law somewhere. Each case turns on its own facts.

That a formula appears on the IRS's list at all should be a warning, not a reassurance: examiners flag formula-driven salaries precisely because they're so often used to justify an artificially low wage. A percentage of profits is not a market rate.

Think about why a percentage formula doesn't work:

A management consulting firm earning $500,000 in revenue with one owner-employee who does all the work has a very different salary profile than a retail store earning $500,000 with one owner who manages a team of employees and significant inventory. The consultant's labor is the entire revenue engine. The retailer's labor is one input among many (inventory, real estate, employees). A 60/40 split applied to both businesses produces the same result, but the market value of the owner's labor in each business is completely different.

That's the fundamental problem with any percentage approach. It's based on the business's financials, not on the market value of the owner's services. The IRS's standard is "what would you have to pay someone to do this work," not "what percentage of profits should go to salary."

Tax Court has applied this reasoning in exactly the way you'd expect. In Sean McAlary Ltd., Inc. v. Commissioner (T.C. Summary Op. 2013-62), a real-estate broker's S corp reported gross receipts of $518,189 and paid its sole shareholder-employee $240,000 in distributions while reporting zero wages. The court had to set a reasonable salary. It declined to be swayed by a percentage-of-receipts comparison — finding that part of the expert analysis not "persuasive or helpful" — and instead landed on a market figure built from Bureau of Labor Statistics wage data: roughly $40 per hour across a 2,080-hour year, for reasonable compensation of $83,200. The methodology that carried the day was occupation-specific market data, not a ratio. Reasonable compensation, the court reaffirmed, is what the work is worth on the open market, derived factor by factor — not a slice of the P&L.

The lesson is consistent across the reasonable-compensation case law. Formulas don't decide these cases. Market data does.

Why this is getting more scrutiny, not less

Underpaid S-corp salaries are squarely on the government's radar. A 2021 report from the Treasury Inspector General for Tax Administration (TIGTA) (Report No. 2021-30-042) found that for processing years 2016–2018, 266,095 S-corp returns had profits over $100,000, a single shareholder, and no officer's compensation reported — yet were not selected for examination. Those owners reported about $108 billion in profits and took roughly $69 billion in distributions while paying themselves nothing in wages. TIGTA estimated this single pattern may have left nearly $25 billion in compensation unreported and about $3.3 billion in employment taxes uncollected. The report also noted the IRS examines less than 1 percent of S corporations and urged it to close the gap.

The takeaway for owners: the zero-salary and lowball-salary playbook is exactly what regulators are pushing the IRS to pursue. A defense that rests on a 60/40 rule of thumb — rather than on documented market data — is precisely the kind of position that doesn't survive the heightened attention.

What the IRS actually looks at

Instead of a formula, the IRS evaluates each situation based on the nine factors from Fact Sheet FS-2008-25. We walk through all nine in detail in The Nine IRS Factors for Reasonable Compensation. The short version:

Your actual duties and how you spend your time. The IRS wants to know what you do, not just that you own the business. If you spend 30% of your time on bookkeeping, 25% on sales, 20% on operations, and 25% on client delivery, each of those tasks has a market value. That's a fundamentally different analysis than applying a percentage to your P&L.

What comparable roles pay in your area. The Bureau of Labor Statistics publishes wage data for 800+ occupations across 500+ metropolitan and nonmetropolitan areas. This is the data source the IRS references in its own analyses. A management consultant in San Francisco has a different market rate than a management consultant in Des Moines. A percentage formula ignores geography entirely.

Your training, experience, and qualifications. A surgeon with 20 years of experience commands different compensation than a recent medical school graduate, even if they own similar practices. Market data accounts for this through percentile distributions. A formula doesn't.

The economic conditions and context of your business. A growing business with increasing revenue might justify a salary increase. A struggling business in a declining industry might justify lower compensation. These are facts-and-circumstances judgments that a formula can't capture.

What to do instead

Drop the percentage. Do the actual analysis.

Match your tasks to market data. Identify the specific tasks you perform in the business and match each one to a BLS occupation code for your metropolitan area. This is what the Cost Approach (the "Many Hats" method) does, and it's one of the IRS-recognized methodologies for determining reasonable compensation. See Cost Approach vs. Market Approach for how both methods work.

Here's the contrast in concrete terms. Suppose your S corp nets $200,000. The 60/40 rule says pay yourself $120,000 — full stop, regardless of what you actually do. The market-data approach asks a different question: what does the work cost? If you spend half your week running operations as a general/operations manager and half doing the specialized client work your business sells, you price each role at the BLS wage for that occupation in your metro and at the time you actually devote to it. That number might come out higher than $120,000, or lower — the point is it's tethered to evidence an examiner can check, not to your profit margin. In McAlary, that's exactly the logic the court used: it didn't take a percentage of $518,189 in receipts; it priced the broker's labor at the BLS rate for the work and arrived at $83,200.

Use a recognized data source. BLS wage data is free, public, and verifiable. It's the same data the IRS uses. When your report cites a specific occupation code, geographic area, data year, and percentile, an IRS examiner can verify every number independently. That's transparency.

Document the methodology. Show how you got from your duties to your salary number. The steps should be clear enough that someone who doesn't know your business can follow the logic and check the math.

Update annually. Even if your duties haven't changed much, market rates shift. BLS publishes updated wage data every year. Your salary analysis should reflect current data for the tax year in question.

Don't forget the board resolution. A one-paragraph resolution in your corporate minutes documenting that the salary was reviewed and approved based on market data analysis. One paragraph, and you have a dated paper trail.

The 60/40 rule is popular because it's easy. But the IRS doesn't grade on ease. They grade on defensibility. And a formula-based approach is the opposite of defensible.
