The reasonable compensation question is the single most common audit issue for S-Corps. The IRS knows that the S-Corp structure creates a tax incentive to minimize the owner’s salary (subject to FICA) and maximize distributions (not subject to FICA), and it has won case after case where owners paid themselves unreasonably low salaries. In Watson v. Commissioner (2012), an accountant with an S-Corp earning $200,000+ in profit paid himself a $24,000 salary and took the rest as distributions; the court found the salary unreasonable and reclassified a significant portion of the distributions as wages. The analysis comes down to a facts-and-circumstances test: what would a hypothetical employer pay a non-owner employee to do the work the owner does? The IRS considers the owner’s qualifications, the nature and scope of the services, the time devoted to the business, comparable salaries in the industry and geographic area, the complexity of the business, and the gross and net income of the business. There is no safe harbor percentage, no magic ratio, and no formula in the code. The best defense is a documented analysis using compensation data from sources like the Bureau of Labor Statistics, Robert Half Salary Guide, or industry-specific surveys, supporting the salary as comparable to what the market would pay for the same work.

✓Key takeaway

Factors the IRS considers for reasonable compensation:

Factor	What the IRS Looks At
Training and experience	Education, certifications, years of experience in the field
Duties and responsibilities	What the owner actually does (management, sales, production, all of the above)
Time and effort	Full-time vs. part-time; hours devoted to the business
Comparable salaries	What similar businesses pay for similar positions (market data)
Compensation history	What the owner has been paid in prior years
Business revenue and profitability	Higher revenue / profitability generally supports a higher salary
Dividend history	A history of large distributions with minimal salary is a red flag
Location	Cost of living and prevailing wages in the geographic area
Use of a formula	Compensation agreements that tie salary to revenue or profit are considered

Key court cases:

Case	Outcome
Watson v. Commissioner (2012)	Accountant’s $24,000 salary on $200K+ profit reclassified; court set reasonable salary at $91,044
Radtke v. United States (1990)	Attorney took $0 salary; all “dividends” reclassified as wages
David E. Watson, P.C. (2012)	Same as Watson; demonstrates the IRS’s focus on personal service S-Corps
JD & Associates (2012)	Orthodontist’s low salary reclassified
Nu-Look Design (2012)	Owner of home improvement company; salary too low relative to duties and revenue

What is reasonable compensation and how do you set it?

Hypothetical example

Round numbers. An S-Corp owner operates a consulting business. The S-Corp has $400,000 in net income before the owner’s compensation. The owner performs all consulting work, manages the business, and works full-time (2,000+ hours/year).

Setting reasonable compensation:

Step 1: Research comparable salaries

Source	Comparable Position	Salary Range
BLS (Bureau of Labor Statistics)	Management consultant, senior	$120,000-$180,000
Robert Half Salary Guide	Consulting manager	$130,000-$170,000
Industry survey (profession-specific)	Principal consultant, 15+ years	$140,000-$200,000
Geographic adjustment (high-cost area)	+10-15%

Step 2: Document the salary determination

Factor	Analysis	Salary Supported
Owner’s role	CEO + principal consultant + sales + administration	Higher end (multiple roles)
Experience	20 years in the field, MBA	Higher end
Time devoted	Full-time (2,000+ hours)	Full-time salary
Revenue	$400,000+	Supports $150,000+
Geographic area	Major metro, high cost of living	+15%
Reasonable salary determination		$160,000

Tax impact at $160,000 salary:

Item	Amount
S-Corp net income	$400,000
Owner salary	$160,000
Employer FICA (6.2% SS on $160K + 1.45% Medicare)	$12,240
Net income after salary and employer FICA	$227,760
S-Corp distribution	$227,760
Total payroll tax (employer + employee FICA)	$24,480

Compare: salary too low ($60,000)

Item	Amount
Owner salary	$60,000
Employer FICA	$4,590
Distribution	$335,410
Total payroll tax	$9,180
Payroll tax “savings” from low salary	$15,300

If the IRS reclassifies distributions as wages:

Consequence	Amount
Additional wages reclassified	$100,000 (bring $60K up to $160K)
Back employer FICA on $100,000	$7,650
Back employee FICA on $100,000	$7,650
Failure to file/deposit penalty (IRC 6656)	$1,500-$3,000
Interest on underpayment	$2,000-$4,000
100% trust fund recovery penalty (if willful)	$7,650 (the employee’s share)
Total cost of reclassification	$26,450-$30,950

The $15,300 in payroll tax “savings” from the low salary costs $26,450-$30,950 if challenged, plus audit costs and the risk of additional scrutiny on other items.

Salary that is too HIGH is also a problem: If the S-Corp pays the owner $350,000 (leaving only $50,000 as profit):

Issue	Details
Excess salary reduces QBI	More salary = less QBI = smaller QBI deduction (if eligible)
Unnecessary payroll tax	FICA on $350K: $26,775 (vs. $24,480 on $160K, but the Medicare portion on $190K extra = $2,755 + 0.9% additional = $4,465)
IRS rarely challenges salaries as too high in S-Corps	But it could reduce the QBI deduction by $38,000 ($190K x 20%), costing $14,060 in tax

Optimal salary framework:

Business Net Income	Approximate Salary Range	Distribution
$75,000	$50,000-$60,000	$15,000-$25,000
$150,000	$80,000-$100,000	$50,000-$70,000
$250,000	$100,000-$140,000	$110,000-$150,000
$400,000	$140,000-$180,000	$220,000-$260,000
$600,000	$160,000-$220,000	$380,000-$440,000
$1,000,000+	$200,000-$300,000+	$700,000-$800,000

These ranges are illustrative and depend on the owner’s role, industry, geographic area, and comparable market data. There is no safe harbor formula.

How to defend your salary if audited:

Documentation	Purpose
Written salary study (compensation analysis)	Shows the research behind the salary determination
BLS / salary survey data	Third-party market data supporting the salary
Job description	Documents what the owner actually does
Time records	Shows hours worked
Board resolution or meeting minutes	Formal approval of compensation by the board
Industry benchmarks	Comparable companies in the same industry
Prior-year consistency	Consistent salary history (not a sudden drop)
