S Corp Reasonable Compensation: Setting a Salary That Holds Up

Every S corporation tax saving comes from one place: profit taken as a distribution is not subject to self-employment or payroll tax, and salary is. That gap is the entire strategy, and it is also the entire audit risk. The IRS does not need to challenge your election or your deductions to collapse the benefit — it only needs to decide your salary was too low.

This is the most consequential number in the whole exercise, and the one the internet is most confident and least reliable about. Before you get here you should already understand what the election is, have decided it is worth making, and know how to file Form 2553.

There is no percentage rule

The most repeated piece of advice in this area is the so-called 60/40 rule: pay yourself 60% of profit as salary and take 40% as distributions. It has no statutory authority, no regulatory authority, and no case-law authority. It appears nowhere in the Internal Revenue Code, the regulations, any revenue ruling, any revenue procedure, or any IRS publication. It is a practitioner rule of thumb that got repeated until it started to sound official.

The same goes for every variant — 50/50, one-third salary, "a third, a third, a third". None of them is a safe harbor. None of them is a defense.

What the standard actually is

An officer of a corporation who performs more than minor services is an employee of that corporation, and payments for those services are wages. That is the starting point, and it is not optional — you cannot avoid it by choosing not to run payroll.

The measure of how much is set out in the compensation regulation under section 162, which the IRS and the courts apply on both sides of the question:

It is, in general, just to assume that reasonable and true compensation is only such amount as would ordinarily be paid for like services by like enterprises under like circumstances.

Treas. Reg. §1.162-7(b)(3)

Like services, like enterprises, like circumstances. That is a market question, not an accounting one. The practical translation: what would you have to pay a stranger with your skills to do your job, for the hours you actually work, in your industry, in your city?

Notice what is absent from that test. Profit is not in it. The business's results affect your salary only to the extent they would affect what a comparable employer would pay a comparable employee.

The factors that decide it

When the IRS examines owner compensation it works through a familiar set of factors, and the courts have used substantially the same list for decades. No single factor controls; they are weighed together.

The case law runs one way and has for a long time. Revenue Ruling 74-44 established that distributions paid in place of reasonable compensation can be recharacterized as wages, and the courts have repeatedly upheld that treatment where a shareholder performed substantially all the work of a profitable business and drew a token salary. The most-cited modern example is the Watson litigation, in which a CPA firm's sole owner took a small wage alongside large distributions; the court accepted the government's expert valuation of his services and recharacterized the difference. What decides these cases is almost always evidence — whose expert had better comparables, and whether the taxpayer had any contemporaneous basis for the number at all.

Building a figure you can defend

The defensible approach is boringly mechanical. You are not trying to find the lowest number that survives; you are trying to produce a number with a paper trail behind it.

1. 1Write the job description first

   Before you look at any tax number, write down what you do. A typical owner-operator is simultaneously the practitioner, the salesperson, the operations manager and the bookkeeper. Split your working hours across those roles.

2. 2Price each role at market

   Use outside wage data: Bureau of Labor Statistics occupational employment and wage statistics, your state's labor department data, industry association salary surveys, and live job postings for the same role in your metropolitan area. Save the pages with the date you pulled them.

3. 3Blend by hours, then scale to reality

   Weight each rate by the share of hours it represents to get a full-time blended figure, then scale it to the hours you actually work. A genuine twenty-hour week supports roughly half a full-time wage — but only if your calendar, invoices and job records support the claim.

4. 4Sanity-check against the business

   Compare the result to what you pay employees, to what you paid yourself last year, to the distributions you plan to take, and to what the company can actually fund. If the number is larger than the profit, the answer is a smaller distribution, not a smaller wage.

5. 5Adopt it in writing before the first payroll run

   A dated memo setting out the analysis, plus a short written compensation agreement or board resolution adopting the figure. Do this in January, not in April of the following year.

Where salary meets the QBI deduction

This is the part almost no article gets right, and it can reverse the direction of the whole decision.

The Section 199A qualified business income deduction is now permanent at 20% — the sunset that had been scheduled after 2025 was repealed by the One Big Beautiful Bill Act, so any source telling you it expired is stale. Every dollar you pay yourself as W-2 wages reduces qualified business income by that dollar. Below the income threshold, that means roughly a third of the headline payroll-tax saving from a lower salary is clawed back through a smaller deduction. The saving is real, but it is smaller than the raw FICA arithmetic suggests.

Above the threshold — for 2026, $403,500 of taxable income for joint filers and $201,750 on most other returns, phasing over the next $150,000 and $75,000 respectively — the sign flips. Past the phase-in the deduction is capped by a wage limitation: broadly, 50% of the W-2 wages the business pays, or 25% of wages plus 2.5% of the unadjusted basis of qualifying property. A sole proprietor pays no W-2 wages at all, so that cap squeezes their deduction toward nothing. An S corporation paying real wages keeps deduction capacity worth up to half of what it pays.

The mechanics are worth seeing plainly. While the wage cap is the binding constraint, an extra dollar of salary costs you twenty cents of deduction through lower qualified business income but buys fifty cents of deduction capacity through the cap. It is a net gain until the two lines cross. At the same time, once salary passes the Social Security wage base — $184,500 for 2026 — the marginal payroll cost of another dollar of salary falls from about 15.3% to 2.9% in Medicare tax, plus 0.9% Additional Medicare Tax above $200,000 single or $250,000 joint, thresholds that are fixed in statute and never indexed. Cheap marginal salary plus a binding wage cap is why, at higher incomes, cutting your salary can cost more than it saves.

What happens if the IRS disagrees

The adjustment is not a simple reclassification with a matching refund. When distributions are recharacterized as wages, the following typically follow together:

• Both halves of FICA on the recharacterized amount — the employee's 7.65% and the employer's 7.65% — plus FUTA, for every year under examination.
• Failure-to-deposit penalties on employment tax that was never deposited, which escalate with lateness.
• Failure-to-file and failure-to-pay penalties on the payroll returns that were never filed for those quarters.
• An accuracy-related penalty, commonly 20% of the underpayment, where the position lacked a reasonable basis.
• Interest running from the original deposit due dates, not from the date of the assessment.
• Knock-on adjustments — corrected Forms W-2 and 1120-S, an amended shareholder return, and a recomputed Section 199A deduction.

There is a further wrinkle worth knowing: a payroll return that was never filed generally leaves the assessment period open indefinitely. An owner who has taken distributions and filed no Forms 941 has no closing years behind them.

What none of this requires is bad faith. The examiner does not have to prove you were hiding anything. They have to conclude that the wage you paid was below what like services would command in like enterprises — and if you have no documentation, that conclusion is easy to reach and hard to rebut.

Patterns that draw attention

• A zero salary with meaningful distributions. The single highest-risk pattern. If money left the company for a working owner, some of it was wages.
• A salary that is a suspiciously round share of profit. It signals that the number was derived from the profit, which is precisely the wrong input.
• A salary that never changes while revenue triples. Market wages move; a frozen number looks like a plug.
• Owner pay below employee pay for less demanding work in the same business.
• A salary set exactly at the Social Security wage base. Stopping at the cap is a tax-driven number, not a market one, and it reads that way.
• Everything paid in one December lump. Legal, but it invites the question of whether the figure was chosen for the work or for the year-end result.

The annual rhythm

Reasonable compensation is not a one-time decision made when you file Form 2553. Set the figure before the first payroll period of the year, using data you pulled this year. Run payroll on schedule with proper withholding and quarterly filings — the election means nothing in practice until you do. Revisit the number whenever your role materially changes: a new hire who takes over half your work, a shift from practitioner to manager, a genuine drop in hours. Keep each year's memo and its sources in one place, permanently.

One thing this guide deliberately does not do is give you a number. Anyone who offers one without seeing your role, your hours, your industry and your market is guessing, and their guess will not be in the file when it matters. If you are still weighing the structure itself rather than the salary within it, LLC versus S corp covers that comparison directly, and the S-corp rules in your state cover the local side of it.
