Reasonable Compensation for S-Corp Owners

Why "reasonable" is the most expensive word in S-Corp tax

You elected S-Corp status because someone told you it would save you payroll taxes. They were right — but only if you handle one rule correctly. Get it wrong and you'll owe the back FICA you tried to avoid, plus penalties, plus interest, and you'll spend a year of your life producing wage surveys for an IRS examiner.

The rule is "reasonable compensation." If you're an S-Corp shareholder who works in the business, you must pay yourself a salary through payroll before you take distributions. Not after. Not "next year when cash is better." Through W-2 payroll, with FICA withheld and a 941 filed every quarter. The amount has to be reasonable for what you actually do — meaning what someone would pay an arm's-length employee to do that exact job in your market.

There is no safe harbor. There is no IRS-approved percentage. There is only a body of court cases, a set of factors the IRS evaluates on audit, and your documentation. This article walks through what "reasonable" actually means, how to use Bureau of Labor Statistics data to land on a defensible number, and what the audit trigger zone looks like.

What "reasonable compensation" actually means

The IRS position is straightforward and has been litigated repeatedly: an S-Corp shareholder who performs services for the corporation is an employee, and the corporation must pay that employee reasonable compensation for those services before distributing remaining profit as a shareholder distribution. This rule exists because S-Corp distributions are not subject to FICA tax. Without the rule, every S-Corp owner would pay themselves $1 in salary and call the rest a distribution.

The Eighth Circuit decided the cornerstone case, Watson v. United States, in 2012. David Watson was an accountant. His S-Corp paid him a $24,000 salary while distributing roughly $204,000 in profits. The court agreed with the IRS that $24,000 was unreasonably low for an experienced accountant generating that much revenue, recharacterized $67,044 of the distributions as wages, and assessed back FICA, the failure-to-deposit penalty, and interest. The Supreme Court declined to hear the appeal.

Two follow-on cases tightened the rule further. Sean McAlary Ltd. v. Commissioner (2013) confirmed the IRS will recharacterize even when the owner's stated salary was based on some calculation — if the calculation is sloppy, the IRS replaces it with theirs. Glass Blocks Unlimited v. Commissioner (2013) is the case every owner needs to know: the company lost money that year, paid zero salary, and the Tax Court still recharacterized distributions as wages. A loss year does not exempt you from reasonable compensation if you took distributions.

The pattern across these cases: the IRS does not need to prove your number is wrong. It needs to show its number is more reasonable than yours. Whoever brought better data wins.

The four factors the IRS uses on audit

When an examiner challenges your salary, they apply a multi-factor test that has emerged from the case law and IRS training materials. There is no scoring formula — the examiner weighs the factors and reaches a conclusion. You need to be able to defend each one with documentation.

How to use BLS data to benchmark your salary

The Bureau of Labor Statistics publishes the Occupational Employment and Wage Statistics (OEWS) survey twice a year. It contains median, mean, and percentile wage data for roughly 800 occupations, broken out by state and metropolitan area. This is the single most important free resource for setting reasonable compensation, and it is the same dataset the IRS uses on audit.

Here is the workflow. Identify the SOC code (Standard Occupational Classification) that matches what you actually do. Pull the wage data for your specific metro area, not the national average. Adjust for your hours and experience level using the percentile data — the 25th, 50th (median), 75th, and 90th percentiles are all published. Document where the number came from.

1. Define the role honestly. If you do graphic design for clients, you are a Graphic Designer (SOC 27-1024) for that work. If you also run sales, you are partly a Sales Manager (SOC 11-2022). Most owners blend two or three roles — weight them by hours.
2. Look up the metro area, not the country. Go to bls.gov/oes and select your metropolitan statistical area. A graphic designer earning the median in Miami earns substantially less than the same role's median in San Francisco.
3. Pick the percentile that matches your experience. The median (50th percentile) is the default for an experienced owner doing the work. A new entrant might justify the 25th percentile. A 20-year senior might justify the 75th. Going below the 25th without strong reason invites scrutiny.
4. Convert annual to your actual hours. BLS data assumes full-time. If you work the business 25 hours a week, you can pro-rate down. Document the hours.
5. Save the source. Print or PDF the BLS page with the date you pulled it. Save your hours log. Save your role description. This is your audit defense file.

Some practitioners use commercial reasonable compensation report services (RC Reports, RCReports, and similar) that produce a written report based on BLS data plus IRS-court-case methodology, typically for $200 to $500. The output is the same data you can pull free from BLS, packaged with a methodology narrative. For owners with complex multi-role situations or strong audit risk, the cost is reasonable insurance.

The audit trigger zone

The IRS does not publish its audit selection criteria, but the patterns from examination practice are clear. Three configurations attract attention faster than anything else.

One more pattern worth flagging: salary that does not move year over year while profits grow significantly. If the business doubled in profit but salary stayed flat, the examiner reads that as proof you are using payroll as a tax-management lever rather than as compensation for services. Salaries should move with role, hours, and market — not with whatever number you decided three years ago.

Worked example — Sarah benchmarks her S-Corp salary

Sarah runs a Florida design studio. She elected S-Corp status last year. Her 2026 net business profit before owner compensation is projected at $130,000. She works the business full-time, roughly 45 hours a week, doing client design work, sales calls, and administration. She is the only employee. She needs a defensible salary number for 2026.

Sarah pulls the BLS OEWS data for her metro (Tampa-St. Petersburg-Clearwater). She identifies two SOC codes that map to her work: Graphic Designer (27-1024) for the production work, and roughly 20% of her time as Sales Manager (11-2022) for client acquisition. She uses median wages for both, since she has nine years of experience but is not a senior-level practitioner.

Sarah's FICA on $72,000 of W-2 wages comes to $11,016 total — $5,508 withheld from her paycheck and $5,508 paid by the S-Corp as the employer match. The $58,000 distribution is not subject to FICA, which is the legitimate S-Corp benefit. If she had instead paid herself $30,000 and taken $100,000 as a distribution, she would have saved $6,426 in FICA in the short term — and put a Watson-sized target on her return. The numbers in this example use illustrative BLS medians as of early 2026; pull current values from bls.gov for your own filing.

Documentation checklist — what to keep on file

If your salary is ever challenged, the case turns on what you can produce. Build the file before you set the salary, not after the audit letter arrives.

• Written job description. One page listing the duties you actually perform, the SOC codes that map to them, and a percentage breakdown of time spent on each.
• BLS source documents. PDF or screenshot of the BLS OEWS page for your metro and SOC code, with the date you pulled the data.
• Hours log or summary. Average hours per week worked in the business. A simple weekly time tracker is sufficient.
• Salary memorandum. A short internal document — one page is fine — explaining how you arrived at the number, signed and dated. This is what an examiner reads first.
• Annual review. Repeat the analysis every year. If your role changed, hours changed, or BLS data moved meaningfully, the salary should reflect that.
• Payroll records. Form 941 quarterly filings, W-2 at year end, and proof of timely federal tax deposits.

What happens if you got it wrong

If you've been running an S-Corp with no salary or an obviously low salary, you are not the first owner in that position. The path forward is to fix the current year before the IRS notices, not to wait. For the current year, set up payroll, run a defensible salary the rest of the year, and document the methodology. For prior years, the conversation gets harder — amending payroll returns triggers FICA and penalties, but doing it voluntarily is far cheaper than doing it under examination.

One important note: the failure-to-deposit penalty for unpaid payroll taxes ranges from 2% to 15% depending on how late the deposit is, plus interest, plus the failure-to-file 941 penalty if returns weren't filed at all. None of these are dischargeable in a casual conversation with the IRS. This is a situation where talking to a qualified tax professional before you take any visible action is worth the call.

Common mistakes

• Taking zero salary "until the business is bigger." The Glass Blocks case settled this — distributions trigger reasonable comp, regardless of profit.
• Using a flat 60/40 rule without market data. The 60/40 split is industry shorthand, not a defense. The IRS does not care what your accountant's rule of thumb is.
• Setting salary once and never revisiting. Salary should move with role, hours, and market. A flat salary across years of profit growth is its own audit signal.
• Ignoring multi-role reality. If you're producer, marketer, and CEO, your salary should reflect a blend of those rates — not just the cheapest one.
• Skipping documentation. The BLS data is free and public. Not pulling it before setting your salary is the difference between defending an audit and conceding it.
