Every S-Corp shareholder who performs services for the corporation must receive “reasonable compensation” before taking distributions. This requirement comes from IRC 3121(a) (defining wages) and has been affirmed by the Tax Court in cases like Watson v. Commissioner (2012) and Radtke v. United States (1990). The IRS position is straightforward: if a shareholder performs services that would normally be compensated, the corporation must pay wages subject to FICA. The S-Corp can’t avoid employment taxes by paying a below-market salary and extracting the remaining profit as distributions. On the other side, overpaying salary wastes money on unnecessary FICA taxes. The optimal salary is the minimum amount that the IRS would consider reasonable for the services actually performed, supported by comparable salary data and documented analysis.

✓Key takeaway

The IRS reasonable compensation factors (from Revenue Ruling 74-44 and case law):

Factor	What the IRS Examines
1. Training and experience	Education, certifications, years in the industry
2. Duties and responsibilities	What the shareholder actually does day-to-day
3. Time and effort devoted	Hours worked per week, full-time vs. part-time
4. Comparable salaries	What similar positions pay in the local market
5. Dividend history	Has the company ever paid dividends/distributions? Pattern matters.
6. Compensation agreements	Is there a written employment agreement?
7. Use of a formula	Is compensation tied to revenue, profit, or performance?
8. Company’s financial condition	Revenue, profit, assets, growth trajectory
9. Compensation compared to distributions	Ratio of salary to distributions (red flag if salary is very low relative to distributions)

What triggers IRS scrutiny:

Red Flag	Risk Level
$0 salary with large distributions	Very high (virtually guaranteed reclassification)
Salary under $30,000 with $200,000+ distributions	High
Salary significantly below industry norms	High
Salary-to-distribution ratio under 30%	Moderate to high
No payroll at all (distributions only)	Very high
Salary decreases as profits increase	High
Multiple owners, only some take salary	Moderate

How do you determine the right salary for an S-Corp owner?

Hypothetical example

Round numbers. A CPA who operates a tax practice as an S-Corp. 15 years of experience. Works 50 hours/week during tax season, 30 hours/week off-season (average ~40 hours/week year-round). S-Corp revenue: $400,000. Net profit (before owner compensation): $300,000.

Step 1: Research comparable salaries

Source	Comparable Salary
Bureau of Labor Statistics (BLS): Accountants and Auditors, 75th percentile	$98,000
Robert Half Salary Guide: Senior CPA, 15+ years, similar metro	$115,000-$140,000
AICPA compensation survey: Solo practitioner, similar revenue	$120,000-$160,000
Glassdoor: Tax Manager, similar experience	$105,000-$130,000
Reasonable range	$110,000 - $150,000

Step 2: Set salary within the reasonable range

Salary Option	Distributions	Total FICA	Income Tax Effect	Total Tax
$110,000 (low end)	$190,000	$16,830	Lower (more QBI)	Lower total
$130,000 (mid-range)	$170,000	$19,890	Moderate	Moderate
$150,000 (high end)	$150,000	$22,950	Higher (less QBI)	Higher total

Tax comparison at different salary levels:

Component	$110,000 Salary	$130,000 Salary	$150,000 Salary
Employer FICA (7.65%)	$8,415	$9,945	$11,475
Employee FICA (7.65%)	$8,415	$9,945	$11,475
S-Corp deduction (employer FICA)	($8,415)	($9,945)	($11,475)
QBI (distributions are QBI)	$190,000	$170,000	$150,000
QBI deduction (20%)	$38,000	$34,000	$30,000
Net federal tax savings (110K vs. 130K)	~$4,060 savings	Baseline	~$4,060 higher

Choosing $110,000 over $130,000 saves ~$4,060 per year. But is $110,000 defensible?

Step 3: Document the analysis

Documentation	Purpose
Comparable salary research (BLS, Robert Half, AICPA)	Proves salary is within market range
Job description (duties performed by shareholder)	Defines the role being compensated
Time log or estimate (hours per week)	Shows effort level
Revenue and profit history	Context for the compensation decision
Board resolution setting compensation	Formal corporate record
Written employment agreement	Establishes the compensation arrangement

Step 4: Consider the IRS’s Watson v. Commissioner analysis In Watson, the Tax Court found that an accounting firm owner paying himself $24,000 on $200,000+ of firm profit was unreasonable. The court used an independent compensation study to set reasonable compensation at ~$93,000.

Watson Comparison	Watson Case	This CPA
Owner’s salary	$24,000	$110,000
Firm profit (before salary)	$200,000+	$300,000
Salary/profit ratio	12%	37%
Industry comparison	Well below market	Within market range
IRS challenge risk	High (and they won)	Low

The $110,000 salary is defensible because:

It falls within the documented comparable salary range ($110,000-$150,000)
The salary-to-profit ratio (37%) is reasonable
The CPA has a written job description and employment agreement
Comparable salary data supports the amount
The salary is consistent year-to-year (not suspiciously reduced as profits increase)

What happens if the IRS reclassifies distributions as wages: If the IRS determines that $110,000 is too low and the correct salary is $150,000:

Item	Amount
Additional wages reclassified	$40,000
Employer FICA (7.65%)	$3,060
Employee FICA (7.65%)	$3,060
Failure to deposit penalty (late FICA)	$1,530 (25% of total FICA)
Interest on late FICA	~$500
Total additional cost	~$8,150

The reclassification is expensive, but the penalty structure is proportional. This is why setting salary at the low end of the defensible range (not below it) is the optimal strategy: it minimizes FICA while staying within the range the IRS would accept.
