S-Corp Reasonable Compensation: Setting the Owner’s Salary

Under Treasury Regulation § 1.162-7(b)(3) and 26 U.S.C. § 162(a)(1), there is no IRS formula and no magic percentage. Examiners decide it on the facts, weighing a multi-factor test drawn from case law; IRS Fact Sheet FS-2008-25 lists nine of those factors. Three factors carry most of the weight: what the owner actually does, what the market pays for that work, and the skill and experience the owner brings to it.

The market answer comes from real wage data — the Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) program, which covers hundreds of occupations across more than 500 metropolitan and nonmetropolitan areas. WageProof turns that into a specific, defensible number: it breaks the owner’s role into its component tasks, prices each against the right occupation and local pay percentile, and produces a documented analysis to file with the corporate minutes or hand to an examiner — built on the same kind of public wage data used to benchmark reasonable compensation.

Reasonable compensation is the wage an S corporation pays a shareholder who also works in the business — the owner-employee — for the services they personally perform. The law requires that this salary be paid (and payroll taxes withheld on it) before the owner takes any profit out as a distribution.

The standard comes from Treasury Regulation § 1.162-7(b)(3), which defines reasonable compensation as “such amount as would ordinarily be paid for like services by like enterprises under like circumstances.” The underlying statute, 26 U.S.C. § 162(a)(1), allows a business to deduct “a reasonable allowance for salaries or other compensation for personal services actually rendered.” The IRS applies the same standard to S-corp officers in Fact Sheet FS-2008-25.

One practical way to picture it is replacement cost: if the owner walked away tomorrow, what would the company have to pay an unrelated person to do everything they do? That amount — adjusted for the owner’s skills, the industry, and the local labor market — is one well-supported way to arrive at the figure (the IRS Job Aid’s “cost approach”), weighed alongside what the market pays for the role.

A few things reasonable compensation is specifically not:

• Not a formula. There is no IRS-approved percentage split between salary and distributions; the S-corp salary 60/40 rule is a rule of thumb with no IRS document behind it.
• Not the owner’s cash needs. The mortgage, the lifestyle, and how much the owner happens to want to take home are irrelevant. Market data is what matters.
• Not a set-it-and-forget-it number. Duties change, the business changes, and wage data is updated every year. Revisit the figure annually.

There is no fixed amount: the IRS publishes no salary figure and no percentage for any role. The salary is set from three things: the duties the owner actually performs, local BLS wage data for the matching occupation, and the owner’s experience, which sets where in the local pay range the wage falls. When the owner splits time across several kinds of work, each kind can be matched to its own occupation, priced at that occupation’s local rate, and weighted by the time spent on it.

The worked example on the methodology page shows that calculation task by task, and the reasonable compensation calculator page walks through what the owner provides and how WageProof turns it into a documented figure.

The whole tax advantage of an S corporation lives in one split: salary versus distributions. Salary is subject to FICA payroll taxes — 15.3% in total (12.4% Social Security up to the annual wage base, plus 2.9% Medicare). Distributions of profit carry no FICA. That is the built-in incentive: every dollar shifted from salary to distribution saves payroll tax.

The IRS knows that incentive runs in exactly one direction, which is why S-corp officer pay is a standing enforcement priority. The agency’s job is to make sure the salary reflects the genuine market value of the owner’s work — not a number set artificially low to minimize payroll tax. When the salary is too low, the IRS can reclassify distributions as wages and collect the tax that should have been paid, with interest and possible penalties.

One countervailing pressure is worth naming, because it pushes owners the wrong way. The Section 199A qualified business income (QBI) deduction interacts with the owner’s salary — W-2 wages are generally not themselves qualified business income — which can tempt owners to keep salary low. But the interaction cuts both ways: above certain income levels the deduction is itself capped by the W-2 wages the business pays, so paying more can actually raise it. Either way, chasing the QBI benefit is not a defense for an unreasonably low wage. We work through the trade-off in detail in How the QBI Deduction Affects Your S-Corp Salary Decision.

Because there is no formula, the IRS and the courts decide reasonableness on the totality of the facts. The multi-factor approach traces to Mayson Mfg. Co. v. Commissioner, 178 F.2d 115 (6th Cir. 1949), the case most often credited with articulating it. The IRS lists nine factors the courts have considered in Fact Sheet FS-2008-25:

1. The training and experience the owner brings to the role
2. The owner’s duties and responsibilities
3. The time and effort devoted to the business
4. The history of dividends and distributions
5. What the company pays non-shareholder employees for comparable work
6. The timing and manner of any bonuses to key people
7. What comparable businesses pay for similar services
8. Whether there is a formal compensation agreement
9. Whether compensation is set by a formula

Courts decide on the facts and circumstances of each case, with no single factor decisive. In practice the analysis usually turns on comparable market pay for what the owner actually does: the IRS Job Aid says the reconciliation “will generally rest heavily on the market approach.” A salary that matches the market wage for the owner’s real duties lines up with the method examiners rely on most.

We break down each factor, with how examiners actually apply it, in The 9 IRS Factors for Reasonable Compensation, Explained.

The Reasonable Compensation Job Aid for IRS Valuation Professionals describes three accepted ways to arrive at a number. Any one of them can support your number; in our experience, cross-checking with a second approach makes the documentation harder to challenge.

1. Cost Approach — decompose the owner’s job into its component tasks (the “Many Hats” method), price each task at the market wage for that work, and add them up.
2. Market Approach — match the owner to a single comparable occupation and use the market wage for it.
3. Income Approach — the Independent Investor Test, articulated in Elliotts, Inc. v. Commissioner, 716 F.2d 1241 (9th Cir. 1983), and prominently adopted in Exacto Spring Corp. v. Commissioner, 196 F.3d 833 (7th Cir. 1999), which asks whether a hypothetical outside investor would be satisfied with their return after the owner’s compensation.

WageProof implements all three. Our methodology page shows exactly how each one works and which data feeds it.

If the IRS concludes the salary was unreasonably low, it reclassifies the shortfall — treating distributions as wages. The consequences stack up:

• Back employment taxes on the reclassified amount (both the employer and employee FICA shares when the owner already drew some W-2 salary; a reduced IRC §3509 rate on the employee’s share generally applies when the owner drew none)
• Interest, which usually runs from the date the payroll tax was originally due. Interest can be avoided in one case. If the business agrees to the examiner’s figures on Form 2504, the IRS form for agreeing to additional payroll tax, and pays the tax by the time it files that form, the correction can be interest-free. That relief is not available if the same issue came up in an examination of an earlier period, if the business knowingly underreported, or once the IRS has assessed the tax and demanded payment.
• A potential 20% accuracy-related penalty under Section 6662 — though this is fact-dependent and can be abated for reasonable cause; it is not automatic

Reasonable compensation reports for CPAs and EAs give the return preparer a dated, sourced analysis for each client’s file.

The case law shows how this plays out, and how much documentation matters:

The IRS does not just want a number; it wants to see how the figure was reached. A defensible reasonable compensation analysis has five parts:

1. A specific description of the owner’s duties. Not “I run the business,” but a breakdown of the tasks the owner performs and roughly how their time is split — bookkeeping, sales, client work, operations, marketing, and so on.
2. Market data from a recognized source. The BLS Occupational Employment and Wage Statistics program is one such source: public, free, and broken down by occupation, local wage area (metro or nonmetro), and wage percentile.
3. A transparent methodology. How the tasks were matched to occupations, adjusted for experience level, and accounted for geography — clear enough that an examiner can follow and check it.
4. More than one approach. Running the analysis under more than one IRS-recognized approach lets the methods cross-check each other and shows the number was reasoned from multiple methods rather than resting on a single calculation.
5. A board resolution. A record in the corporate minutes, made at the time, showing the salary was reviewed and approved based on the data — worth far more than an analysis assembled after an audit notice.

This is exactly what WageProof produces: the owner describes the role, WageProof matches those tasks to BLS wage data for the local wage area and experience level, and the result is a documented report — with every wage figure checkable against BLS.gov — ready to attach to the corporate minutes and hand to a CPA or an examiner. See a sample report to view the format.

Reasonable compensation is an annual exercise, not a one-time decision. The number is worth revisiting when any of the following change:

• The owner’s duties or the time spent on the business shift materially
• The business grows, contracts, or changes what it does
• BLS publishes new wage data (it is updated annually)
• The business hires or loses staff who absorb tasks the owner used to handle

A fresh, dated analysis each year is itself a strong record made at the time: it shows the salary was set deliberately, on current market data, rather than picked once and left to drift.
