Watson v. United States: The S-Corp Salary Case Every Practice Owner Should Know

The strategy looked clean on paper: run your professional practice through an S corporation, pay yourself a modest salary, and take the rest as distributions. Distributions skip self-employment and FICA taxes. Salary does not. The math seems obvious, until a federal circuit court makes an example of it.

What Actually Happened in Watson v. United States

David E. Watson was not a naive taxpayer. He was an experienced CPA who operated through his wholly owned S corporation. His S corporation paid him a salary of approximately $24,000 per year. During the same period, it passed through profit distributions of roughly $200,000. Watson reported the distributions as non-wage income, which is not subject to employment taxes.

The IRS examined the returns and made an argument that has become the textbook example of reasonable-compensation enforcement: the salary was artificially suppressed to avoid FICA taxes on income that was, in economic substance, compensation for services Watson personally performed. The government brought in an expert witness who analyzed Watson's experience, credentials, and the market value of the services he rendered. That expert concluded a reasonable salary was approximately $91,000, not $24,000.

The district court agreed. Watson appealed. The Eighth Circuit affirmed in 2012. Watson owed back employment taxes, plus interest and penalties, on the recharacterized wages. The case is now a fixture in every serious conversation about S-corporation compensation planning.

Why the S-Corp Salary Strategy Exists and Where It Breaks

The appeal of the S corporation structure for practice owners is real and legitimate. When a sole proprietor or partner earns income, the entire net amount is generally subject to self-employment tax up to applicable wage bases. An S corporation, by contrast, passes through profits to shareholder-employees, and only the salary portion is subject to FICA. Distributions from an S corporation are not wages, so they are not subject to that payroll tax layer.

That distinction is not a loophole. It is how Congress designed the structure. The problem arises when a shareholder-employee pays themselves a salary so far below market value that the compensation label becomes fictional. The IRS is specifically authorized to reclassify distributions as wages when the salary is unreasonably low.

Watson illustrates the breaking point with precision. A $24,000 salary for a credentialed CPA producing a high volume of professional revenue is not a judgment call. It is a number chosen to minimize taxes rather than to reflect the value of services performed. Courts and the IRS are not required to respect that choice.

What "Reasonable Compensation" Actually Means

The Internal Revenue Code requires S-corporation shareholder-employees who perform services to receive reasonable compensation before taking distributions. The IRS has published guidance on the factors used to evaluate reasonableness, and courts have developed a body of case law around the concept. Common factors include:

• The individual's training, experience, and credentials
• The duties and hours actually worked
• What comparable businesses pay for similar services
• The relationship between salary and distributions (a very low salary alongside very high distributions draws scrutiny)
• Whether the compensation policy has a reasonable business justification

None of these factors produce a single correct number. They produce a defensible range. The goal of reasonable-compensation planning is to arrive at a salary that falls within that range and can be supported with documentation if examined.

For a dental practice owner, this is not abstract. A dentist producing significant clinical revenue, managing staff, and operating a complex small business is providing services with measurable market value. Dental associate salaries and dentist compensation surveys from industry organizations create a visible benchmark. Paying yourself half or less of what a comparable associate would earn, while taking the remainder as distributions, is exactly the fact pattern courts have found problematic.

The Specific Risk for Professional-Practice S-Corp Owners

Practice owners in dentistry, medicine, and professional services face a particular version of this risk because the business's revenue is so directly tied to the owner's personal labor. A passive investor in an S corporation who draws distributions may have a reasonable argument that distributions reflect a return on capital rather than compensation. A dentist whose chair time generates the practice's revenue has no comparable argument.

The IRS has historically targeted:

• Shareholders who are the primary or sole revenue producers
• Cases where distributions are a very large multiple of salary
• Cases where salary remains static while distributions grow substantially
• Industries with well-documented compensation benchmarks (healthcare is one of them)

Watson matters because it confirms the IRS will bring outside expert testimony to establish a market rate, and courts will credit that testimony when the actual salary is dramatically below it. The recharacterization in Watson was not a partial adjustment. It moved roughly three-quarters of the compensation-equivalent income from distributions back to wages.

What Practice Owners Should Actually Do

The Watson case is not an argument against the S-corporation structure. It is an argument for using the structure correctly. Practical steps that belong in any serious S-corp compensation review:

Benchmark regularly. Compensation surveys from dental associations, healthcare staffing firms, and comparable job market data provide external anchors. Your salary should be explainable by reference to what the market pays for the role you actually fill.

Document the analysis. A contemporaneous memo or compensation study prepared with your CPA, reviewed at least annually, creates a record that the salary was set by reference to market factors rather than tax minimization.

Watch the ratio. There is no statutory salary-to-distribution ratio, but a very high distribution-to-salary ratio is a documented audit trigger. Understanding how your ratio compares to industry norms is relevant.

Consider both the payroll tax savings and the exposure. The financial case for an S corporation depends on the net benefit after accounting for the cost of doing it correctly, including reasonable payroll taxes on a defensible salary, payroll processing, and potential audit risk on an aggressive position.

Work with advisors who know professional practices. Dental and medical practices have documented compensation benchmarks that make reasonable-compensation analysis more concrete than in many other industries. An advisor unfamiliar with those benchmarks is working without a map.

The structure rewards discipline. The taxpayer in Watson did not lose because S corporations are disfavored. He lost because the salary he chose bore no rational relationship to the value of his services.

FAQ

Does Watson apply outside the Eighth Circuit? The Eighth Circuit covers seven states. Its holding is not binding on other circuits, but the reasoning has been widely cited and the IRS applies the reasonable-compensation doctrine nationally. No circuit has disagreed with the underlying principle.

Is there a safe harbor salary percentage? No statute or regulation establishes a percentage. Common references to paying "at least 40% as salary" or similar rules of thumb have no official source. The standard is market-based reasonableness, not a fixed ratio.

What if my practice is not yet profitable? A practice generating losses or minimal net income may have a reasonable basis for a lower salary. The analysis still requires documentation. A business that sustains low-or-no salary for years while distributions grow warrants a fresh look.

Could the IRS recharacterize past years? Yes, subject to statute of limitations rules. If the IRS determines compensation was unreasonably low, it can assess back employment taxes, interest, and penalties for open years.
