S-Corp Reasonable Compensation — What the IRS Actually Looks For

By Paul D. Diaz, EA, MBA ·

The S-corp election saves most of my clients more money than any other single structural change. It converts self-employment tax leakage into dividend distributions that are exempt from the 15.3% payroll tax. But the IRS knows this, and the mechanism they use to challenge aggressive S-corp structures is the reasonable compensation rule.

The rule is simple in principle. If you are a more-than-2% shareholder of an S-corp and you provide services to the business, you must be paid a wage that a hypothetical independent investor would consider reasonable for the work you perform. The rest of the profit can be taken as distributions. The wage is subject to payroll taxes. The distributions are not.

The IRS does not publish a dollar figure or a formula. What they do is publish the factors their examiners use, and those factors have been refined through decades of Tax Court decisions. The core test asks: what would an unrelated party charge to perform the services you provide to your own company? If the answer is $120,000 and you are paying yourself $20,000, the IRS will recharacterize distributions as wages and assess back payroll taxes, penalties, and interest.

The factors that matter are: your training and experience, the nature and scope of your services, the time you devote to the business, the size and complexity of the operation, the cost of comparable services in your geographic market, and the overall profitability of the business. The last factor is the one that catches people. If your business is highly profitable and you are the primary service provider, a low salary becomes indefensible. The profit itself is evidence that your services are valuable.

What I tell clients is this. Set the salary at a level you can defend to an examiner without sweating. Use compensation studies from your industry and region. Document the analysis. If you are in a service business where you are the product — which is the case for most of my clients — the salary should be the primary driver of the business income, and the distributions should be the residual.

The interaction with the QBI deduction makes this more nuanced. Your salary reduces your qualified business income, which reduces the Section 199A deduction. There is a balance point where the payroll tax savings from a lower salary are offset by the lost QBI deduction. Finding that point is not guesswork. It is arithmetic, and Chapter 7 of the Guide walks through the calculation with worked examples.

The S-corp election is one of the best tools in the tax code for high-earning independent contractors and small business owners. But it only works if the compensation is set correctly the first time. Retroactive recharacterization is expensive, and it is entirely avoidable.

If you are operating as a sole proprietor or single-member LLC and earning above $80,000 net, you should have the S-corp conversation now, not after the IRS starts asking questions. Type your situation into the chat on this page and I will tell you whether the numbers justify the election.
