Reasonable compensation for an S corp is the salary an unrelated employer would pay someone to do the work you actually do for your business, at a comparable company in the same geographic area. There is no fixed dollar figure and no percentage the IRS blesses as safe. The number turns on your specific duties, the market rate for that work, and how the business performs. Get it wrong on the low side and the IRS can reclassify your distributions as wages, then add back taxes, interest, and penalties that easily exceed whatever payroll taxes you tried to skip.
Why the Number Matters
Every dollar paid as W-2 salary carries a combined FICA cost of 15.3 percent: 12.4 percent for Social Security and 2.9 percent for Medicare.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates The Social Security portion stops at $184,500 in wages for 2026; the Medicare portion has no cap.2Social Security Administration. Contribution and Benefit Base Wages above $200,000 for single filers or $250,000 for joint filers trigger an additional 0.9 percent Medicare surtax.3Internal Revenue Service. Topic No. 560, Additional Medicare Tax The corporation also owes federal unemployment tax of 0.6 percent on the first $7,000 of each employee’s wages, plus state unemployment.4Employment & Training Administration – U.S. Department of Labor. FUTA Credit Reductions
S corporation distributions carry none of these taxes. That gap is why shareholders are tempted to pay themselves a small salary and pull the rest as distributions, and it is exactly the behavior the IRS scrutinizes. The requirement is baked into the tax code: businesses can only deduct compensation that is “a reasonable allowance for salaries or other compensation for personal services actually rendered.”5Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses And under longstanding IRS guidance, an S corporation must pay a shareholder-employee reasonable compensation before making any non-wage distributions.6Internal Revenue Service.

What the IRS Actually Looks At
The IRS has published the specific factors examiners weigh when deciding whether a shareholder’s salary was reasonable.7Internal Revenue Service. Wage Compensation for S Corporation Officers They cluster into three groups.
What you do. The nature and scope of your duties, the hours you put in, the training and experience required for the work, and your role in generating the corporation’s revenue. An owner running every department and working long weeks warrants meaningfully more pay than one who checks in monthly.
What the market pays. Compensation for comparable roles at comparable businesses in your industry and geography, along with any formulas the corporation uses to set pay for other employees.
How the business handles money. Dividend history, the ratio of salary to distributions, what non-shareholder employees are paid, and the timing and manner of any bonuses. A corporation paying its owner $40,000 while distributing $300,000 draws obvious attention.
The burden of proving reasonableness sits with the corporation. And the analysis turns on whether payments genuinely reflect the value of services performed, not on what the shareholder “intended” to pay.8Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers
Three Methods for Setting the Salary
The IRS Reasonable Compensation Job Aid, used by the agency’s own valuation professionals during audits, describes three approaches.9Internal Revenue Service. Reasonable Compensation Job Aid for IRS Valuation Professionals Building your salary using the same methods the agency uses is the strongest starting position.
Cost (Replacement) Approach
Break your workload into functions and price each one separately. If you spend 10 percent of your time on bookkeeping, 30 percent on sales, and 60 percent on engineering, look up the going rate for each role and blend them by time allocation. The IRS uses this method specifically when a shareholder argues that long hours and multiple hats justify a high salary, because it forces each hat to be valued individually rather than as a lump sum.
Market Approach
Ask what an unrelated company would pay a non-owner to do the same job. The Bureau of Labor Statistics publishes Occupational Employment and Wage Statistics covering roughly 830 occupations, with breakdowns by state and metropolitan area.10U.S. Bureau of Labor Statistics. Occupational Employment and Wage Statistics Overview Localized wage data beats a national average, and this is typically the first comparison an examiner runs.
Income (Independent Investor) Approach
Look at the corporation’s overall financial performance and ask whether an outside investor would consider the return on invested capital reasonable after the shareholder’s salary is paid. If the business is profitable and the owner’s salary swallows nearly all of the profit, something is off. If a fair salary leaves a healthy return flowing to shareholders as return on capital, an investor would be satisfied. The method is designed to separate the value of the owner’s personal labor from the return generated by the company’s assets, brand, and customer base.
A salary that lands inside the range produced by all three methods is much harder for the IRS to challenge than one supported by a single number.
The 60/40 Rule Is Not an IRS Standard
A widely repeated rule of thumb says to pay yourself 60 percent of profits as salary and take 40 percent as distributions. That ratio has no basis in the tax code, IRS regulations, or case law. It is practitioner shorthand. The IRS does not judge your salary against your distributions in a vacuum; it judges whether the salary fairly compensates the work you perform. A 60/40 split can be too high, too low, or roughly correct depending on the facts, and reciting the ratio during an audit is not a defense.
How Salary Affects Your Retirement Contributions
Your W-2 salary caps how much you can shelter in a retirement plan. S corporation distributions do not count as earned income for retirement plan purposes.11Internal Revenue Service. Retirement Plan FAQs Regarding Contributions – S Corporation With a solo 401(k), you can defer up to $24,500 as an employee in 2026, plus employer contributions of up to 25 percent of your W-2 wages.12Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026 A SEP IRA lets the corporation contribute up to the lesser of 25 percent of compensation or $72,000.13Internal Revenue Service. SEP Contribution Limits
The math shifts fast. A shareholder paying themselves $60,000 maxes the SEP at $15,000. Bump the salary to $120,000 and the SEP cap jumps to $30,000. The extra payroll tax on that additional wage is real, but the retirement shelter and long-term compounding often outweigh it.
What Happens If You Set Salary Too Low
When the IRS decides a shareholder’s salary was unreasonably low, it reclassifies a portion of the distributions as wages under the authority of IRC Section 7436.14Internal Revenue Service. 4.8.10 Notice of Employment Tax Determination Under IRC 7436 The bill that follows has several layers.
The corporation owes the employer’s share of FICA on the reclassified amount and the employee’s share it failed to withhold, plus FUTA and state unemployment. Interest runs from the original due date and compounds quarterly. The failure-to-file penalty runs 5 percent per month up to 25 percent, and failure-to-pay adds 0.5 percent per month, also capped at 25 percent.15Internal Revenue Service. Failure to File Penalty16Internal Revenue Service. Failure to Pay Penalty If the IRS characterizes the low salary as negligence, it can add an accuracy-related penalty of 20 percent of the underpayment.17Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments
Courts have consistently rejected the argument that a corporation “intended” to pay low wages. The pattern is straightforward: the more the business depends on the shareholder’s personal labor, the more of its income the IRS will treat as wages.8Internal Revenue Service.

Documentation to Have on File
The best defense in a reasonable compensation dispute is paper you created before the return was filed. Assemble a justification after an audit notice arrives and it looks like exactly what it is. Before year-end, your file should contain:
- At least one independent salary survey or compensation study showing what comparable roles pay in your industry and area. BLS wage data by occupation and metro area is free and credible.
- A written job description covering your actual responsibilities, required qualifications, and hours worked. If you fill multiple roles, break out the time allocation for each.
- Board minutes or a corporate resolution authorizing the officer’s salary. Even a single-shareholder S corporation should record that the board reviewed compensation data and discussed the basis for the amount chosen.7Internal Revenue Service. Wage Compensation for S Corporation Officers
- A short valuation memo applying the cost, market, or income approach (ideally all three), particularly when the corporation’s revenue is high or the salary is substantial.
Most S corporations fall short here. The salary itself may be perfectly reasonable, but without contemporaneous records the corporation is left saying “trust us” to an examiner whose job is not trusting you.
Loss Years and Situations Where the Rule Bends
Reasonable compensation is based on the value of your services, not on whether the business earned a profit. A break-even year does not automatically excuse you from running payroll. The core rule: wages come before distributions. If the business earns less than a reasonable salary would be, you can pay whatever is available as wages, but you cannot take distributions until the salary obligation is satisfied.
There is one genuine escape valve. If you take no money out of the corporation at all in a given year, you are not required to run payroll. The requirement kicks in when cash leaves the corporation and reaches you.8Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers Be careful with workarounds. Shareholder “loans” that the IRS concludes were disguised distributions get treated as distributions that should have been preceded by reasonable compensation. Distributions that exceed your stock basis are taxed as capital gains regardless of the corporation’s own profitability.18Internal Revenue Service. S Corporation Stock and Debt Basis
A Note on Health Insurance for 2 Percent Shareholders
If you own more than 2 percent of the S corporation, health insurance premiums the company pays on your behalf must be included in Box 1 wages on your W-2. Those premiums are not subject to Social Security, Medicare, or unemployment taxes as long as the plan is available to employees generally, and you can claim an above-the-line deduction on your personal return.6Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues The premiums must flow through payroll first.
Several fringe benefits available to rank-and-file employees are off-limits to more-than-2-percent shareholders: health flexible spending arrangements, health reimbursement arrangements, and qualified small employer HRAs. These exclusions catch owners by surprise, especially former C corporation shareholders where those benefits were fully excludable.
