One of the most consequential and most commonly mishandled requirements in S Corporation operation is the reasonable compensation analysis. The Internal Revenue Service requires S-Corp shareholders who perform services for the corporation to take a reasonable salary before distributions. Salary that is too low triggers IRS challenge, reclassification, and potential back-payroll taxes plus penalties. Salary that is too high unnecessarily increases payroll tax exposure and reduces the tax benefit of the S-Corp election.
The difference between defensible and indefensible compensation carries meaningful annual tax consequences, both as direct tax cost and as IRS audit risk. AE Tax Advisors conducts formal reasonable compensation analysis for S-Corp shareholder clients as part of the firm’s S-Corp election and ongoing advisory work.
The technical framework for reasonable compensation analysis is built around the IRS’s published guidance and the substantial body of case law that has developed around shareholder compensation disputes.
The most authoritative IRS guidance is contained in the Internal Revenue Manual sections addressing S-Corporation examinations, along with the IRS Fact Sheet on Reasonable Compensation. The guidance identifies multiple factors that should be considered in setting a reasonable salary, including the training and experience of the shareholder-employee, the responsibilities and duties performed, the time spent on the business, comparable salaries in similar positions, the size and complexity of the business, the corporation’s compensation policy for non-shareholder employees, the relationship between dividend distributions and compensation, and other relevant factors.
The case law has developed across decades of IRS challenges to S-Corp compensation. The most influential cases, including Glass Blocks Unlimited v. Commissioner and David E. Watson, P.C. v. United States, have established that the IRS will substitute its own reasonable compensation determination for the shareholder’s actual salary when the actual salary is found to be unreasonably low. The reclassification typically results in substantial back-payroll taxes, interest, and penalties.
The AE Tax Advisors approach to reasonable compensation analysis involves several specific components.
The first component is the role analysis. The shareholder-employee’s actual duties and responsibilities are documented. This includes hours spent on the business, specific functions performed, decision-making authority, and the value the shareholder personally brings to the operation as distinct from passive equity ownership.
The second component is the comparable compensation research. AE Tax Advisors uses industry compensation data, geographic adjustments, business-size comparisons, and other reference points to identify what comparable workers earn for similar work. The research uses defensible sources (published compensation surveys, government data, and industry-specific benchmarks) that would support the determination in an IRS examination.
The third component is the business analysis. The compensation has to reflect the business’s actual capacity to support it. A business with minimal revenue cannot defensibly pay a market salary for a senior position because the business’s economics would not support it. AE Tax Advisors integrates the business financial analysis with the role and market research to identify the defensible range.
The fourth component is the documentation. The analysis is documented in a written report that includes the methodology, the sources consulted, the analysis conducted, and the conclusion reached. The documentation is the audit defense. If the IRS challenges the compensation, the report serves as the supporting analysis.
The fifth component is the annual update. Reasonable compensation is not set once and forgotten. As the business grows, the role evolves, and market conditions change, the analysis should be revisited. AE Tax Advisors’ annual $7,800 advisory engagement includes the periodic update of the reasonable compensation analysis to reflect changes in the business and the market.
The work is integrated with the broader S-Corp election and ongoing operational work that AE Tax Advisors handles. When the firm executes an S-Corp election through Form 2553, the reasonable compensation analysis is part of the election engagement. When the firm provides ongoing payroll setup and administration, the salary structure reflects the documented analysis. When the firm conducts the proprietary 3-Year Tax Lookback, prior year compensation is evaluated for defensibility and potential exposure.
The firm’s team, which includes IRS Enrolled Agents and licensed CPAs led by Christina Nortman, has built specific expertise in the reasonable compensation area. The Enrolled Agent designation in particular reflects training specifically in IRS examination matters, which means the team understands how IRS examiners actually evaluate compensation positions.
The work matters because the alternative is bad. S-Corp owners who take artificially low salaries to maximize distributions face real audit risk. The IRS examination of S-Corp compensation has become more common over the past decade, and the outcomes for taxpayers without defensible analysis have generally been negative. Owners who have completed the analysis enter the examination with a documented position supporting their salary determination.
For S-Corp shareholders who have not formally documented their reasonable compensation position, a formal analysis is one step toward closing that gap. The analysis is technical. The documentation is defensive. And the team’s specific expertise in this area is one dimension of how AE Tax Advisors approaches business tax advisory work.
