S-Corp Reasonable Compensation: The Audit Trigger in Your Payroll

The S-corp salary game is the most oversold move in small-business tax, and the version most people run is not aggressive planning. It is a defect waiting to be assessed. A single-owner S-corp that pays its sole worker-owner nothing, or a token $12,000, and then sweeps $180,000 out as distributions has not found a loophole. It has built an audit narrative and handed the IRS the pen.

The logic that gets people here is sound as far as it goes. Distributions from an S-corp are not subject to the 15.3 percent combined Social Security and Medicare tax that hits wages; only the W-2 wage line runs through payroll tax. So every dollar you can honestly call a distribution instead of a salary saves you roughly fifteen cents on the first $168,600 of earnings (the 2024 Social Security wage base) and 2.9 percent above it. Multiply that across a profitable practice and the incentive is obvious. The problem is the word honestly.

The statute does not care what saves you tax

The governing rule is short and old. Under §3121(a) and §3121(d)(1), an officer of a corporation who performs services is an employee, and payments for those services are wages subject to FICA. The IRS position, restated in Rev. Rul. 74-44 and every audit guide since, is that an S-corporation must pay its shareholder-employees reasonable compensation for services before making distributions. There is no dollar threshold in the Code that tells you what reasonable means, which is exactly why the temptation exists and exactly why it is dangerous. You are not choosing between a safe number and a risky number. You are choosing a number that a revenue agent, and possibly a Tax Court judge, will later grade against the facts.

The courts have been clear about the direction of the analysis. In David E. Watson, P.C. v. United States (8th Cir. 2012), a CPA paid himself $24,000 in salary while taking roughly $200,000 in distributions from his one-person accounting firm. The court did not accept the salary. It recharacterized a large share of the distributions as wages, using an expert's figure for what a comparable CPA would earn, and the firm owed the payroll tax plus penalties. The lesson is not that $24,000 is always wrong. It is that a number picked to minimize FICA, rather than to describe the value of the work, will not survive contact with an expert report.

Zero salary is not a position, it is a flag

Paying yourself nothing while the S-corp distributes six figures is the single loudest signal available. The IRS knows that an active owner of a profitable single-shareholder corporation is working, and a Form 1120-S showing large distributions with a blank or trivial officer-compensation line (that is line 7, "Compensation of officers," on the 1120-S) is the kind of return that gets pulled. When it does, the burden of explaining the number is on you, and "my accountant said to keep the salary low" is not an explanation the examiner records with sympathy.

The recharacterization is not the whole cost. When distributions become wages after the fact, you owe the employer and employee FICA, plus the failure-to-deposit penalty under §6656, plus the failure-to-file penalties for the payroll returns that were never filed, plus interest running from the original due dates. A move that was supposed to save fifteen cents on the dollar can end up costing more than the tax it deferred, because you are now paying the tax you avoided plus a stack of penalties for the manner in which you avoided it.

I worked with an IT consultant, married filing jointly, sole owner of an S-corp that cleared about $190,000 in a strong year. His prior preparer had set his salary at $30,000 and run the other $160,000 out as distributions, on the theory that a low salary was simply efficient. What made his case worse than the raw ratio was the documentation, or the absence of it. He had no engagement to support the $30,000 as a market rate, and his own LinkedIn described him as a senior architect billing $185 an hour. That self-description was the problem. We could not defend $30,000 against his own public account of what his time was worth, so we rebuilt the compensation from the bottom up: a wage study using the hours he actually spent on billable work versus administrative and passive management, which landed his defensible salary near $110,000 with the balance as distribution. Higher salary, more FICA, and a return that would no longer draw a second look. He was annoyed. He was also, for the first time, correct.

How you actually build a defensible number

The right method is the one the experts use against you, run in your own favor first. Reasonable compensation is the value of the services the shareholder personally performs, not a percentage of profit and not a round number that feels safe. The IRS fact sheet on the subject (FS-2008-25) lists the factors examiners weigh: training and experience, duties and responsibilities, time and effort devoted to the business, what comparable businesses pay for similar services, and the use of a formula to determine compensation. None of that is a formula you can plug numbers into. All of it is a record you either have or do not.

There are two respectable approaches. The cost approach values each function the owner performs, the CFO hours at a CFO rate, the technician hours at a technician rate, and sums them. The market approach finds what a comparable employee doing the whole job would command and adjusts for the portion of income attributable to non-owner labor and capital. For a genuine one-person service business where the owner is the entire product, the two tend to converge, and they rarely converge on a small number. Where the S-corp has real employees, real equipment, or intangible value doing the earning, a lower owner salary can be honest, because a meaningful share of the profit is a return on capital rather than a payment for the owner's labor. That distinction is real, and it is worth documenting precisely because it is the legitimate version of the argument everyone else is faking.

The practical target most planners aim for, and the one I use as a starting sanity check rather than a rule, is a salary that captures the market value of the labor and leaves distributions to represent the return on the business itself. If your entire S-corp is you and a laptop, expect that split to lean heavily toward salary. If you are trying to justify a salary that is a small fraction of what you would pay someone to replace you, you are not planning. You are documenting the deficiency in advance.

The S-corp remains a good structure for the right business, and the FICA savings on genuine distributions are real money. The mistake is treating the salary line as a dial to minimize rather than a fact to establish. Set it from the work, keep the study that supports it, and the audit trigger stops being a trigger. If your entity is already carrying a salary you could not defend to a judge, that is a fixable problem, and it is far cheaper to fix before the letter arrives than after.
