Every S-Corp owner who performs services for the corporation must receive reasonable compensation as W-2 wages before taking tax-free distributions. This is not optional. Under IRC 3121 and the employment tax provisions, an officer of a corporation who performs services is a statutory employee, and the compensation must reflect what a similarly situated employee would be paid in the open market. The tax motivation for S-Corp election is the ability to split income between salary (subject to FICA/Medicare) and distributions (not subject to payroll taxes), saving the 15.3% self-employment tax on the distribution portion. The IRS knows this, and unreasonably low officer compensation is a top audit priority. The 2012 Watson case and 2013 McAlary case both resulted in significant reclassifications and penalties. There’s no safe harbor (such as “pay yourself 60% as salary”), though CPAs commonly use that as a starting framework. The actual determination is fact-specific, and the factors the IRS examines are drawn from case law and Revenue Ruling 74-44.

✓Key takeaway

IRS factors for determining reasonable compensation:

Factor	What the IRS Examines
1. Training and experience	Education, certifications, years in the field
2. Duties and responsibilities	Day-to-day role; is the owner the sole operator or a passive investor?
3. Time and effort devoted	Hours worked; full-time vs. part-time involvement
4. Comparable compensation	What similar positions pay in the same industry and geographic area
5. Complexity and size of the business	Revenue, number of employees, scope of operations
6. Dividend history and distributions	History of paying excessive distributions with minimal salary
7. Compensation formulas	Whether the company uses a reasonable method to set pay
8. Compensation of non-shareholder employees	If non-owner employees doing similar work are paid more
9. Return on equity	Distributions should represent a reasonable return on the owner’s investment, not disguised wages
10. Economic conditions	Local labor market, industry norms

The payroll tax savings (and the audit risk):

Component	Tax Rate	Applies To
Social Security (employer)	6.2%	First $176,100 of wages (2025)
Social Security (employee)	6.2%	First $176,100 of wages (2025)
Medicare (employer)	1.45%	All wages
Medicare (employee)	1.45%	All wages
Additional Medicare	0.9%	Wages over $200,000 single / $250,000 MFJ
Total FICA on wages up to $176,100	15.3%
Total Medicare on wages above $176,100	3.8% (2.9% + 0.9%)

How do you set the right salary to survive an IRS audit?

Hypothetical example

Round numbers. An S-Corp owner is the sole employee of a consulting firm. The business generates $300,000 in net income before owner compensation.

Scenario comparison:

Salary Level	Salary	Distribution	FICA on Salary	Tax Savings vs. All Salary
Too low ($50,000)	$50,000	$250,000	$7,650	$38,250 saved (but audit risk)
Reasonable ($150,000)	$150,000	$150,000	$22,950	$22,950 saved
All salary ($300,000)	$300,000	$0	$37,370	$0 (baseline)

The cost of getting caught: If the IRS reclassifies $100,000 of distributions as wages:

Item	Amount
Back employer FICA (6.2% SS + 1.45% Medicare)	$7,650
Back employee FICA (6.2% SS + 1.45% Medicare)	$7,650
Interest on unpaid taxes (federal underpayment rate, ~8%)	~$1,200/year
Failure to deposit penalty (IRC 6656)	Up to 15% of unpaid deposit
Trust fund recovery penalty (IRC 6672)	100% of employee portion (owner is personally liable)
Late filing penalty (Form 941)	5%/month up to 25%
Accuracy-related penalty (IRC 6662)	20% of underpayment if negligence or substantial understatement

Total potential cost on $100,000 reclassification
Back FICA (employer + employee)	$15,300
Interest (1 year)	$1,224
Failure to deposit penalty (10%)	$1,530
Accuracy penalty (20% of underpaid tax)	$3,060
Total	~$21,114

That’s more than the payroll tax savings from the low salary.

How to document reasonable compensation:

Method	How It Works
Salary surveys	BLS, Salary.com, Glassdoor, Robert Half salary guide for comparable positions in your area
Industry benchmarks	RMA Annual Statement Studies, trade association surveys
Job replacement cost	What would you pay someone to do everything the owner does?
Compensation study	Hire a compensation consultant to prepare a formal study (strongest defense)
Comparable W-2 data	Look at officer compensation on Form 1120-S returns of similar businesses (IRS SOI data)

Reasonable compensation framework (not a rule, but a defensible starting point):

Business Net Income	Suggested Salary Range	Distribution	Rationale
Under $50,000	80-100%	0-20%	Not much room for distributions; salary should reflect full value of services
$50,000-$100,000	60-80%	20-40%	Moderate room; salary should still reflect market rate
$100,000-$200,000	50-70%	30-50%	More flexibility; salary at market rate for comparable position
$200,000-$500,000	40-60%	40-60%	Owner can justify a larger return on equity
Over $500,000	30-50%	50-70%	At higher income levels, return on equity/capital becomes more significant

These ranges are guidelines, not safe harbors. The actual reasonable salary depends on the industry, the owner’s role, and the factors above.

Key court cases:

Case	Facts	Outcome
David E. Watson v. US (2012)	CPA firm, $200K+ income, $24K salary	Court reclassified $120K of distributions as wages; penalties applied
Sean McAlary Ltd. v. Commissioner (2013)	Real estate agent, $224K income, $0 salary	Court determined $100K+ was reasonable compensation
Radtke v. US (1990)	Law firm, $0 salary, all distributions	All distributions reclassified as wages; 100% penalty
Joseph M. Grey Public Accountant (2003)	CPA, $0 salary	All income reclassified; penalties and interest
Joly v. Commissioner (2000)	Construction, $0 salary	Distributions reclassified as wages

The pattern: Courts consistently rule against owners who pay themselves zero or clearly below-market salaries. No court has ever set a specific percentage rule.

Multi-owner S-Corp considerations:

Situation	Rule
Owners with equal duties	Generally should receive similar compensation
Owner who works full-time vs. part-time owner	Compensation should reflect time and effort
Passive investor (no services)	No salary required (but distributions are still not subject to FICA)
Owner who also draws a salary from another employer	Still must receive reasonable compensation from the S-Corp for services performed

When reasonable compensation is already at the Social Security wage base ($176,100):

Income Level	Salary	Additional FICA Cost per $1 of Salary	Marginal Savings from Distribution
Under $176,100	Below SS wage base	15.3% (SS + Medicare)	15.3% per dollar shifted to distribution
Over $176,100	Above SS wage base	2.9% (Medicare only)	2.9% per dollar shifted (much less)

Above the Social Security wage base, the tax savings from taking distributions instead of salary drops from 15.3% to 2.9% (or 3.8% with the Additional Medicare Tax), making the risk-reward ratio much less favorable for aggressive salary reduction.
