Reasonable Compensation for S-Corp Owners: What the IRS Actually Requires
There is no 60/40 rule, no 50% rule, and no published percentage. There is a facts-and-circumstances standard, nine factors, and a body of case law.
Reasonable compensation is the amount an S-Corp must pay a shareholder-employee as W-2 wages for services rendered before making distributions, required because IRC Section 3121(d)(1) treats corporate officers who perform more than minor services as employees. The IRS has never published a safe harbor percentage. The standard is what a comparable business would pay a comparable person for comparable services, determined under a facts-and-circumstances analysis using nine factors developed in case law and summarized in IRS Fact Sheet FS-2008-25.
Why This Is the Most Examined Item on an 1120-S
The S-Corp structure creates an obvious incentive: every dollar moved from wages to distributions saves 15.3% up to the wage base and 2.9% or 3.8% above it. The IRS understands this incentive precisely, and officer compensation is one of the most reliable adjustment items in a small business examination.
The remedy is not subtle. When the IRS recharacterizes distributions as wages, the result is back employment taxes for both employer and employee halves, failure to deposit penalties under Section 6656, failure to file penalties on payroll returns, accuracy-related penalties under Section 6662, and interest, applied across all open years. A three-year adjustment on a meaningfully understated salary regularly exceeds six figures.
The Treasury Inspector General for Tax Administration has repeatedly flagged S-Corp officer compensation as an underreporting area, which keeps enforcement attention on it.
The Nine Factors
IRS Fact Sheet FS-2008-25 and the case law behind it identify the factors that determine reasonableness.
1. Training and experience. Education, credentials, and years in the field.
2. Duties and responsibilities. What the officer actually does day to day, and the scope of authority.
3. Time and effort devoted to the business. Full time, part time, or nominal.
4. Dividend history. A pattern of large distributions with small wages is itself evidence.
5. Payments to non-shareholder employees. If a non-owner manager earns more than the owner, that is difficult to explain.
6. Timing and manner of paying bonuses to key people.
7. What comparable businesses pay for similar services. The core of any defensible analysis.
8. Compensation agreements. Written employment agreements set before the fact carry weight.
9. The use of a formula to determine compensation. A consistent, documented formula applied across years is persuasive.
No factor controls, and the analysis is holistic. But factor 7 is where a defense is built or lost, because it is the only one that produces an objective number.
What the Case Law Establishes
Watson v. Commissioner (8th Cir. 2012) is the leading modern case. A CPA and partner in an accounting firm paid himself $24,000 in wages while taking roughly $175,000 in distributions in each of two years. The court sustained a recharacterization to $91,044 per year, relying on an expert's analysis of what comparable accounting professionals earned. The case establishes that courts will use market compensation data and that a token salary alongside substantial distributions will not survive.
David E. Watson, P.C. v. United States confirmed that the inquiry is what the corporation should have paid for the services actually rendered, not what the shareholder chose to designate.
Radtke v. United States (7th Cir. 1990) addressed the extreme case of an attorney paying himself zero salary and taking all profit as dividends. The court had no difficulty recharacterizing the entire amount as wages.
Spicer Accounting v. United States (9th Cir. 1990) reached the same conclusion where an accountant worked full time and was paid only distributions.
The pattern across these cases is consistent: zero or token compensation for a shareholder performing substantial services fails, and the recharacterized amount is set by reference to market data.
How to Set a Defensible Number
Start with the market rate for the role, not with the profit. The question is what you would have to pay someone else to do what you do.
Use real data sources: Bureau of Labor Statistics Occupational Employment and Wage Statistics, industry salary surveys, trade association compensation studies, and regional adjustments. Where a shareholder performs multiple roles, price each role separately and blend them by time allocation. An owner who spends 60% of their time practicing and 40% managing should be priced against both a practitioner salary and a manager salary.
Adjust for the realities of the business: hours actually worked, whether the owner is part time, the size of the business, and geographic wage differences.
Then sanity check against the business. Compensation cannot exceed what the business can pay, and it should bear a rational relationship to the value the owner's services generate as distinct from the return on invested capital. This is the legitimate argument for a wage below total profit: profit attributable to capital, to other employees, or to intangible assets is a return on investment rather than compensation for services.
Document the analysis contemporaneously, adopt a written compensation agreement, and apply the same methodology consistently each year. A documented, reasoned position is defended very differently from a number chosen at year end.
Common Mistakes
Using a percentage rule. There is no 60/40 rule. It appears in blog posts, not in authority. A 60/40 split can be far too low for a professional services business and far too high for a capital-intensive one.
Setting the wage after the year closes. Compensation for services should be paid as the services are performed. A single December payroll run to true up the year is a recognizable pattern.
Paying zero wages in a profitable year. The clearest way to lose.
Ignoring the multiple-role reality. Owners who both produce and manage are frequently priced against only the lower of the two roles.
Forgetting more-than-2% shareholder health insurance. Premiums must be included in W-2 Box 1 wages to be deductible by the shareholder above the line, and they count toward the compensation analysis.
Ignoring the Section 199A interaction. Above the taxable income thresholds, the QBI deduction for a non-service business is limited by W-2 wages, so an artificially low salary can reduce the deduction by more than the payroll tax it saves.
Correcting a Position That Is Too Low
If prior year compensation was clearly inadequate, the exposure grows with every open year. There are workable paths forward.
Increase current-year compensation to a properly supported level and document the methodology going forward. This does not fix prior years but it stops the accrual and demonstrates good faith.
Where prior years were materially wrong, amended payroll returns and corrected W-2s are possible, and voluntarily correcting before examination substantially improves the penalty posture.
Where the S election itself was a poor fit, revoking it or restructuring may be the better answer than defending an indefensible wage history.
The decision depends on the size of the gap and the number of open years, and it is worth modeling rather than guessing.
Key Takeaways
- No safe harbor percentage exists; the 60/40 rule has no authority behind it.
- Factor seven, what comparable businesses pay, is where a defensible position is actually built.
- Watson, Radtke, and Spicer all establish that token or zero salaries with substantial distributions fail.
- Price each role you perform separately and blend by time allocation.
- Above the Section 199A thresholds, an artificially low wage can cost more in lost QBI deduction than it saves.
Frequently Asked Questions
Is there a 60/40 rule for S-Corp salary?
No. There is no safe harbor percentage anywhere in the Code, regulations, or IRS guidance. The 60/40 rule is an internet convention with no authority behind it. The standard is a facts-and-circumstances analysis against what comparable businesses pay for comparable services.
What happens if the IRS says my salary was too low?
Distributions are recharacterized as wages, producing back employment taxes for both halves, failure to deposit and failure to file penalties, accuracy-related penalties, and interest across all open years. Adjustments spanning three years frequently exceed six figures.
How do I determine a reasonable salary?
Price the roles you actually perform using market data such as BLS Occupational Employment and Wage Statistics and industry salary surveys, blend them by time allocation, adjust for hours and geography, and sanity check against what the business can pay. Document the analysis contemporaneously and apply it consistently.
Can I pay myself zero salary if the business had a loss?
Generally yes. Reasonable compensation is required for services rendered, and where the business genuinely cannot pay, no wage may be appropriate. But taking distributions while paying no wages is the fact pattern that lost in Radtke and Spicer, so distributions and zero wages should not coexist.
Does my health insurance count as compensation?
Yes. Premiums paid for a more-than-2% shareholder must be included in W-2 Box 1 wages, though they are exempt from Social Security and Medicare tax when a proper plan exists. They count toward the total compensation figure in the reasonableness analysis and enable the above-the-line self-employed health insurance deduction.
