S Corp Reasonable Salary: How to Set a Defensible Number

The first year I ran a company through an S corporation, I asked what salary to put myself on and was told to pay myself something reasonable. That was the entire answer. It took me longer than it should have to work out that this was not evasion. There genuinely is no number in the tax code, and producing one is your job.

The consequences run in both directions. Set the salary too low and the IRS can recharacterize your distributions as wages, collect the employment tax you skipped, add penalties, charge interest from old due dates, and reopen filings you assumed were finished. Set it higher than the evidence requires and you hand over payroll tax nobody asked you for.

What follows is the payroll view of the question rather than the tax-return view: how the number gets built, what evidence supports it, and what an examiner looks at. I build people and record-keeping tooling for businesses without an HR department at FirstHR, which is an onboarding and HR platform, not a payroll provider and not a tax adviser. Treat this as general information.

What Reasonable Compensation Means

Reasonable compensation is the amount the corporation would have to pay an unrelated person to perform the services the shareholder actually performs. It is a wage figure derived from work, not from profit, and it is determined before anything is taken as a distribution.

The requirement starts one step earlier than most owners realize. A corporate officer is an employee for Social Security, Medicare, unemployment tax, and income tax withholding purposes, which means the question is never whether you are on payroll. It is only how much of what you took is wages. The mechanics of getting there sit in the wider guide on putting yourself on payroll.

The instructions to the S corporation return put it in one sentence: distributions and other payments to a corporate officer must be treated as wages to the extent the amounts are reasonable compensation for services rendered. That phrase, to the extent, is what creates the whole exercise. It defines a floor, not a cap.

There is a real ceiling worth knowing. Compensation cannot exceed what the shareholder actually received, directly or indirectly. A year in which the company was profitable but you left the money in it, taking nothing and paying no personal expenses through the business, leaves nothing to recharacterize.

The Factors the IRS Lists

The IRS publishes nine factors that courts have used to decide whether compensation is reasonable. They are the closest thing to a checklist that exists, and every one of them is about the work rather than about the profit.

Read that list once and the strategy becomes obvious. Six of the nine are things you control and can document in advance: what you do, how long it takes, what you pay other people, when you pay yourself, whether you have a written agreement, and whether you used a method. Only one, comparable pay, requires outside data, and that data is free.

The full list appears in the IRS fact sheet on wage compensation for S corporation officers, which also confirms the narrow exception for an officer who performs no services and receives nothing.

Why There Is No Percentage Rule

There is no statutory percentage, no safe harbor split, and no IRS-endorsed formula. The IRS says so directly: there are no specific guidelines for reasonable compensation in the Code or the Regulations, and the courts that have ruled on the issue have based their determinations on the facts and circumstances of each case.

That has not stopped the shorthand from spreading. You will hear the 60/40 rule, where sixty percent of profit becomes salary. You will hear the 50/50 rule. You will hear a one third split across salary, distributions, and tax. None of them appears in any authority. They are practitioner habits that got repeated until they sounded official.

The structural flaw in all of them is the same. A profit percentage ties your salary to an output that your labor only partly produces. Profit also comes from capital you invested, from the work of everybody else on your payroll, from equipment, and from market conditions.

Run the logic and it falls apart quickly. A company that doubles profit because a competitor closed did not double the value of your services. A company that loses money because a client went under did not make your services worthless, and yet a percentage rule would cut your salary to nothing in exactly the year an examiner would ask why. The IRS position on recharacterizing distributions is set out in its guidance on S corporation compensation issues.

The Market Rate Method

The market rate method asks a single question: what would this company have to pay somebody else to hold your job? You answer it by matching your role to a published occupation, taking the wage for that occupation, and adjusting for the things that make your situation different.

Take a concrete case. The sole shareholder of a small marketing services company works full time, running the business day to day: setting direction, managing delivery, handling clients, and supervising the people who do the production work. The occupation that fits is general and operations managers.

According to the Bureau of Labor Statistics Occupational Employment and Wage Statistics survey (May 2025), general and operations managers had a national median wage of $50.85 an hour, which the survey annualizes to $105,770, against a national mean of $134,940. That gap is the first decision you have to make consciously.

Two things about that table matter more than the arithmetic. The first is that every row is a decision you can explain. The second is that steps four and six pull in opposite directions, which is normal and is exactly why the reasoning has to be written down rather than reconstructed later.

Choosing the median rather than the mean is defensible for a small business, and the reason is worth stating in your file. Survey means are dragged upward by large employers with large management structures. The median describes the middle of the whole distribution, which is where a small firm actually sits. Do not simply take the lowest available number and stop.

The Cost Approach

The cost approach prices every hat separately. Instead of asking what one replacement would cost, you split your year into hours by function, price each function at its own market wage, and add the pieces into one blended salary.

It suits most small business owners better than the market approach does, because most owners are not doing one job. The same marketing company owner spends part of the year managing, part of it selling, and part of it doing bookkeeping and administration that a clerk would otherwise handle.

The hourly figures come from the same BLS survey, using the occupations that match each function: general and operations managers, sales representatives of services, and bookkeeping, accounting, and auditing clerks. The annual medians for those three occupations were $105,770, $69,990, and $50,670 respectively.

The blended result, roughly $81,260, sits well below the $105,770 the market approach started from. That is not a trick. It reflects a genuine fact about small companies: the owner spends real hours on work the market prices at clerk rates, and pricing those hours at manager rates would overstate the value of the services.

The discipline that makes this defensible is the hour allocation. Guessed percentages are worth very little. Hours taken from a calendar, a time record, or a simple log kept for a representative month are worth a great deal, and they feed the payroll records you should be keeping anyway.

The Independent Investor Test

The independent investor test asks whether, after paying the owner, a hypothetical outside investor would still be satisfied with the return on the equity invested. If the answer is comfortably yes, the compensation is presumptively reasonable.

It arrived through the opposite problem. In Exacto Spring Corporation v. Commissioner (Seventh Circuit, 1999), the dispute was over compensation the IRS thought was too high, and the court reframed the question around investor return: with the owner paid, investors were still earning better than twenty percent, well above the roughly thirteen percent the government expert considered adequate for the risk. The compensation stood.

For an S corporation the concern runs backwards, because the incentive is to set compensation too low. Used in that direction the test becomes a sanity check on your own number. If your company retains a large residual profit after paying you a modest salary, something other than your labor has to explain that residual: capital equipment, other employees, licensed intellectual property, or a genuinely scalable product.

That is the honest question to sit with. A consultancy whose entire output is the owner sitting in client meetings has almost no capital story to tell, and a very large residual after a small salary is difficult to justify. A company with a substantial labor cost base and heavy equipment has a real one.

What the Salary Costs in Tax

The salary carries Social Security and Medicare tax on both sides of the payroll, and that combined 15.3 percent is the entire reason the question exists. Distributions do not carry it, which is what creates the incentive to understate the wage.

Social Security tax is 6.2 percent from the employee and 6.2 percent from the employer, applied to wages up to the annual taxable maximum. For 2026 that maximum is $184,500. Medicare is 1.45 percent from each side with no ceiling, and an additional 0.9 percent is withheld from the employee on wages above $200,000, per the IRS guidance on Social Security and Medicare withholding rates.

The last row is the honest framing of the whole decision. Understating the salary by $41,260 in this example does not save $6,313. It defers $6,313 into a contingent liability that grows with penalties and interest for as long as the position goes unexamined.

Two smaller items belong in the budget. Federal unemployment tax applies at 6.0 percent on the first $7,000 of wages, generally reduced to 0.6 percent where state unemployment tax is paid in full and on time, which is covered in more depth in the guide to FUTA. State unemployment tax applies separately and varies by state and experience rating.

None of this is unique to owners. It is the same FICA arithmetic that applies to every employee on the register, which is precisely the point an examiner will make.

If the IRS Reclassifies

The IRS has the authority to reclassify payments made to shareholders from non-wage distributions, which are not subject to employment taxes, to wages, which are. That authority is stated openly in IRS guidance, and the position dates back decades.

Revenue Ruling 74-44 is the origin. Shareholders of an electing small business corporation performed services, drew no salary, and arranged for the corporation to pay them dividends instead of reasonable compensation. The IRS held those amounts were wages for Social Security, Medicare, unemployment tax, and withholding purposes, and the Tax Court still cites the ruling when the Commissioner recharacterizes a distribution as compensation.

The practical damage is rarely the tax alone. It is the compounding: penalties assessed on amounts that were never deposited on schedule, interest running from original due dates in years you had stopped thinking about, and corrected returns that have to be prepared and filed for each affected period.

There is also a quieter cost. A payroll audit that starts with officer compensation rarely stays there. Once an examiner is inside the payroll records, worker classification, fringe benefits, and expense reimbursements are all within easy reach.

What the Courts Have Done

Court outcomes are the most useful calibration available, because they show what happens when a real number meets a real challenge. Two cases do most of the teaching, and both turned on wage survey evidence.

The McAlary case is the one worth studying, because the government built its position from exactly the same public survey data described earlier in this article. The IRS expert took the survey median for a real estate broker in southern California, $48.44 an hour, multiplied it by a 2,080 hour year, and reached $100,755. The court accepted the method and settled on a lower hourly rate.

Note what the court did not do. It did not invent a percentage, and it did not accept the owner argument that a written pay agreement fixed the value of the services, or that the company belonged at the tenth percentile of comparable businesses. It valued the services. The summary opinion in that case is not precedential, but the reasoning is instructive.

The pattern across both is simple enough to state as a rule. Owners who took a token salary while distributing large sums lost, and the replacement figure was built from published wage data. The evidence that would have defended them is the evidence used against them.

Building the File

The file is the deliverable, not the number. A defensible salary is one accompanied by a short written record showing how it was derived, when it was decided, and what it was based on.

None of this requires a valuation firm. It requires an hour of work, a saved data extract, and the willingness to write down a reason. Storing it alongside your other employment records means it is still findable when somebody asks.

Running It Through Payroll

Once the number exists, the salary has to move through payroll like any other wage: withheld, deposited on the correct schedule, reported quarterly, and reported again on the annual wage statement. A reasonable figure paid the wrong way creates its own problems.

Pay it on a regular cycle. Compensation appearing as one December lump reads as a profit allocation dressed as a wage, and it invites the timing and manner factor to work against you. It also creates a deposit spike large enough to change your obligations without warning.

Keep the two flows visibly separate. Salary runs through payroll with withholding and appears on the quarterly Form 941. Distributions are a separate transaction, recorded separately, with no withholding. Mixing them in the accounting is how a defensible position becomes an unprovable one.

Set the pay period deliberately rather than by default, since the frequency you choose determines your deposit rhythm for the year. The wider mechanics, including the choice of frequency and the deposit schedules that follow, sit in the guide on doing payroll yourself.

One last habit worth building: reconcile the salary you decided on against what actually went out. Plans drift. A figure set in January and quietly underpaid by March is worse than no plan at all, because the file now contradicts the payroll register.
