The S-Corp 60/40 Salary Rule Is a Myth: What Practitioners Actually Use

Somewhere along the way, the internet decided that an S-corp owner should take 60 percent of profit as salary and 40 percent as distributions. It shows up in forums, in YouTube comments, and occasionally in advice from people who should know better. I believed it for about a year. Then I looked for the source and found nothing, because there is nothing to find.

Where the rule supposedly came from

Nobody knows. That is the honest answer. It does not appear in the Internal Revenue Code. It does not appear in any IRS publication, revenue ruling, or notice. No Treasury regulation mentions it. It is folklore that got repeated until it felt official, the tax equivalent of "you only use 10 percent of your brain."

What makes it sticky is that it often produces a plausible number. For a service business earning $150,000, a 60 percent salary is $90,000, which is frequently in the right neighborhood. The rule survives because it is often accidentally correct, not because it is correct.

What the IRS and courts actually said

The legal standard is facts and circumstances. Courts look at training and experience, duties, time devoted, dividend history, pay to non-shareholder employees, and comparable compensation at similar businesses. The comparable pay factor carries the most weight, and it is the one the 60/40 rule ignores entirely.

Tax courts have explicitly rejected mechanical formulas. In the well known cases, Watson and Grey, the issue was never the ratio. The issue was that the owners paid themselves salaries far below what anyone would pay a non-owner to do the same work, then took the rest as distributions. The courts recharacterized the distributions as wages. The lesson was about market rates, not about percentages.

When 60/40 gives you the wrong answer

Take a software engineer billing $400,000 through her S-corp. Sixty percent is $240,000, well above the $184,500 Social Security wage base for 2026. A market rate analysis might support $170,000 for her role and hours. The rule would have her overpay payroll tax on $70,000 of salary for no reason.

Now take a part time e-commerce seller netting $60,000 while working 15 hours a week. Sixty percent is $36,000, but a market rate for 15 hours of warehouse and customer service work might support $20,000. Here the rule overpays too, just in a different direction.

And at $45,000 of profit, the rule says take $27,000 as salary. Many practitioners would tell you that at that profit level there is barely room for a meaningful split at all, and the market rate for the owner's actual work might be 80 percent of profit or more. The ratio breaks at both ends because businesses are not all shaped the same.

What practitioners actually do

Talk to CPAs who defend these in audits and you hear the same sequence. Start with the market rate method: break the owner's work into roles, find what comparable businesses pay for each, weight by hours. That is the primary analysis, the one you document.

Then run the cross checks. The 40 to 60 percent of profit band is one of them. So is the independent investor test: after paying this salary, would the business still show a return that satisfies an investor? So is the cost approach: what would it cost to hire someone else to do this job? None of these are rules. They are lenses, and you look through all of them before you pick a number.

The number that survives all the lenses is the defensible one. Sometimes it lands at 60 percent of profit. That does not make 60/40 a rule. It makes it a coincidence with good PR.

My take

I think the rule persists because it gives anxious owners permission to stop thinking. The IRS question is genuinely uncomfortable: it asks you to value your own labor honestly, in writing, with sources. A percentage lets you skip that. But the skip is exactly what gets people in trouble, because an auditor can see the difference between a derived number and a defaulted one in about ten seconds.

Do the role mix analysis. It takes an afternoon. Print the market data, write the memo, and put it in a folder. That folder is worth more than any ratio.
