There's No 60/40 Rule: How the IRS Actually Decides If Your S-Corp Salary Is Reasonable

Reasonable S-Corp Salary For IRS

Ask five business owners how to set S-Corp salary and at least three will tell you the same thing: pay yourself 60%, take the rest as distributions. It sounds official. It has never once been IRS guidance. There's no formula at all, but that doesn't mean there's no answer, and getting it wrong is a lot more expensive than most owners realize.

The Rule That Isn't a Rule

The "60/40 rule," 60% of profit as salary, 40% as distributions, gets repeated so often in small business forums and even by some preparers that it's treated as settled law. It isn't. The IRS has never published this ratio, never endorsed it, and has successfully challenged plenty of S-Corp owners who followed it to the letter. It's practitioner shorthand that calcified into myth.

What the IRS actually requires is simpler to state and harder to calculate: reasonable compensation, the amount an unrelated person would be paid for performing the same services, in the same role, in a similar business. No percentage. No formula. A facts-and-circumstances test, applied to your specific situation. This question only comes up once you've made the S-Corp election in the first place, if you're still deciding whether that election is worth making, that's covered separately in S-Corp Election for Maryland LLCs: When It Actually Saves You Money.

What the IRS Actually Looks At

The IRS's own Reasonable Compensation Job Aid, used by examining agents, and the body of Tax Court decisions built on top of it, point to the same handful of factors every time:

  • Training and experience. A 20-year specialist commands more than someone a year into the field, regardless of what the business nets.
  • Duties and time devoted. If you're the CEO, the lead technician, and the person answering the phones, your salary should reflect all three roles, and how many hours you're actually working.
  • Comparable salaries. What would this exact job cost if you had to hire it out? This is typically the most heavily weighted factor of all.
  • Dividend and distribution history. A pattern of large distributions next to a token salary is exactly what draws attention.
  • Company size and profitability. A business generating $800,000 with a $40,000 officer salary is, on its face, a red flag.
  • Payments to non-owner employees. If you pay a non-owner manager $70,000 for less responsibility than you carry, that number works against a much lower owner salary.

A second, less commonly discussed lens courts have applied is the "independent investor test": would a hypothetical outside investor in your company be satisfied with their return after your salary is paid? If your compensation is eating the entire profit an investor would expect to see, that's its own kind of red flag, just pointed the opposite direction.

The Case That Changed Everything

The most-cited reasonable compensation case is Watson v. Commissioner, a CPA who paid himself $24,000 a year in salary while his firm generated over $200,000 in income, taking the rest as distributions. The IRS reclassified a large share of those distributions as wages. Watson took it to Tax Court, and lost, then lost the appeal too. The court's reasoning wasn't complicated: a working CPA generating that kind of income for the firm could not credibly be worth only $24,000 to hire.

The number that case and the ones that followed it converge on isn't a ratio, it's a floor: compensation should generally land at or above roughly 70% of what the comparable market rate for the work would actually cost. Below that, the burden of proof gets steep fast.

Two Ways to Get It Wrong, Not One

Most conversations about this only mention the risk of paying yourself too little. There's a real cost on the other side too.

Salary Set Too LowSalary Set Too High
What happensDistributions get reclassified as wages by the IRSYou've paid unnecessary payroll tax on money that could have been a distribution
The immediate costBack payroll taxes, plus penalties that can reach 25% of the underpayment, plus interest7.65% employer-side FICA on every dollar over the reasonable number
The quieter costRetirement contribution room stays artificially capped, since employer plan contributions run off W-2 wagesReduces your Section 199A QBI deduction, since a higher salary shrinks the qualified business income it's calculated from

The right number isn't the lowest defensible one or the highest comfortable one, it's the accurate one. Both mistakes cost real money, just in different directions.

Why This Matters More Now That QBI Is Permanent

The 2025 tax law made the Section 199A qualified business income deduction, worth up to 20% of qualifying business income for pass-through owners, a permanent part of the code rather than the expiring provision it used to be. We cover the mechanics in our full breakdown of the QBI deduction becoming permanent.

Here's why that raises the stakes on this exact question: a lower salary means more of your profit flows through as qualified business income eligible for that 20% deduction, which is now a permanent incentive rather than a temporary one. That's a real, legitimate reason salary optimization matters. It's also exactly the incentive that's drawn heightened IRS attention to reasonable compensation audits, the agency knows the math now cuts more sharply toward underpaying salary than it used to, and enforcement has followed.

How to Actually Document a Defensible Number

The single biggest difference between owners who sail through an inquiry and owners who don't is whether the salary decision was documented before the return was filed, not reconstructed after an audit notice arrives.

  • Pull real comparable wage data. Bureau of Labor Statistics occupational wage data for your role and region is a legitimate, citable source, not a guess.
  • Write a short job description. What you actually do, hours devoted, responsibilities carried. If you're the CEO, the technician, and the office manager rolled into one person, the description should say so.
  • Put the decision in writing. A short compensation memo or a line in your annual meeting minutes, dated, showing you made a deliberate, informed decision rather than picked a number that happened to minimize tax.
  • Revisit it every year. A salary that was defensible at $100,000 in profit can look indefensible at $400,000 in profit with no change. This isn't a set-it-and-forget-it number, especially as the business grows and the decisions around it get more expensive to get wrong.

The S-Corp and Retirement Connection

One more reason to get this number right: it doesn't just affect payroll tax and QBI, it sets the ceiling on how much you can put into a retirement plan. Both a Solo 401(k) and a SEP-IRA calculate their employer contribution off your W-2 wages, not your total business profit, which means an artificially low salary quietly caps your retirement savings at the same time it's saving payroll tax. We walk through that tradeoff, and which plan makes more sense once the salary number is set, in Solo 401(k) vs. SEP-IRA for small business owners.

Frequently Asked Questions

Is the 60/40 rule really not real?

Correct. The IRS has never published or endorsed a 60% salary, 40% distribution ratio. It's a shorthand that spread through small business circles and got mistaken for guidance. The actual standard is reasonable compensation, based on comparable wages and the specific facts of your role, not a fixed percentage of profit.

What happens if the IRS decides my salary was too low?

The IRS can reclassify some or all of your distributions as wages after the fact, which means back payroll taxes on the reclassified amount, penalties that can reach 25% of the underpayment, and interest accruing from when the tax should have been paid. It's a materially more expensive outcome than simply setting the number correctly from the start.

Can my salary be too high?

Yes, and it's a real cost even though it's rarely audited the same way. Every dollar of salary above what's actually reasonable pays unnecessary employer-side payroll tax, and it also shrinks the qualified business income your Section 199A deduction is calculated from. The goal is accuracy, not minimizing salary as far as possible.

How often should I revisit my salary number?

At least annually, and any time the business's profitability changes meaningfully. A salary that was defensible at one profit level can become indefensible at a much higher one if it never moves, since comparable-wage data and your own documented role are both supposed to be current, not set once and forgotten.
