Every S-Corp owner who works in the business must pay themselves a “reasonable salary” through payroll before taking distributions. The IRS does not define a specific dollar amount, but they have successfully challenged $0 salaries and unreasonably low salaries in court. The landmark case is Watson v. Commissioner (2012), where the Tax Court found that $24,000 was not a reasonable salary for an accountant generating $200,000+ in revenue and substituted $93,000. Setting the salary too low triggers audit risk. Setting it too high defeats the purpose of the S-Corp election (reducing self-employment tax on the distribution portion).

✓Key takeaway

What “reasonable” means:

The IRS looks at what the owner would be paid if they were an employee doing the same work for someone else. Factors include:

Training, education, and experience the owner brings
Duties and responsibilities (a CEO/owner who does everything vs. a passive investor)
Time and effort devoted to the business
Comparable salaries for similar positions in similar industries and locations
Compensation history (what did the owner earn before starting the S-Corp?)
Distributions vs. salary ratio (a $200,000 distribution with $0 salary is a red flag)
Total gross receipts of the business (a $1 million business paying its sole owner $30,000 is suspect)

Where to find comparable salary data:

Bureau of Labor Statistics (BLS): bls.gov/oes (Occupational Employment Statistics)
Salary.com, PayScale, Glassdoor
Robert Half Salary Guide (for professional services)
Industry-specific surveys
The owner documents the comparable range and sets the salary within it

Common ranges by industry (sole owner, full-time):

Service trades (plumbing, electrical, HVAC): $45,000-$75,000
Construction contractors: $50,000-$80,000
Professional services (accounting, consulting, law): $60,000-$120,000
IT/software services: $60,000-$100,000
Retail/e-commerce: $40,000-$70,000
Medical practices: $80,000-$200,000+
Real estate agents: $40,000-$60,000 (plus commission structure)

The “60/40 rule of thumb” (not law, but a starting point): Some practitioners suggest 60% of S-Corp net income as salary and 40% as distribution. This isn’t an IRS rule and shouldn’t be the sole basis for setting salary. It fails for both high-income and low-income S-Corps:

At $300,000 net: 60% = $180,000 salary (probably too high for most small businesses)
At $60,000 net: 60% = $36,000 salary (possibly too low for a full-time professional)

The better approach: set salary based on comparable market data, not a percentage of net income.

How do you set a defensible reasonable salary?

Hypothetical example

Round numbers. An S-Corp owner operates a plumbing business. Sole owner, works full-time (50+ hours/week). S-Corp net income before owner’s salary: $140,000. Located in a mid-cost metropolitan area.

Step 1: Find comparable salaries. BLS data for plumbers in the metro area:

Mean hourly wage: $30.50 ($63,440 annual)
75th percentile: $37.00 ($76,960 annual)
90th percentile: $44.00 ($91,520 annual)

A sole-owner plumber is more than a journeyman plumber. They run the business: estimating, marketing, customer management, bookkeeping, in addition to performing plumbing work. The comparable role is closer to a plumbing service manager or small business operator.

Salary.com data for “plumbing supervisor/manager” in the metro area:

Median: $65,000
75th percentile: $78,000

Step 2: Set the salary. Given the owner’s experience (15 years), full-time commitment, and dual role (plumber + business operator), a salary of $60,000-$70,000 is defensible.

Setting it at $60,000:

Employer FICA: $4,590
Employee FICA: $4,590
Total FICA: $9,180
S-Corp net after salary: $140,000 - $60,000 - $4,590 = $75,410 (K-1, no SE tax)
SE tax savings vs. sole prop: $140,000 sole prop SE tax ($19,770) minus S-Corp FICA ($9,180) = $10,590

Setting it at $70,000:

Employer FICA: $5,355
Total FICA: $10,710
S-Corp net: $140,000 - $70,000 - $5,355 = $64,645 (K-1)
SE tax savings: $19,770 - $10,710 = $9,060

Setting it at $50,000 (aggressive):

Employer FICA: $3,825
Total FICA: $7,650
S-Corp net: $140,000 - $50,000 - $3,825 = $86,175 (K-1)
SE tax savings: $19,770 - $7,650 = $12,120

The risk/reward tradeoff:

Salary	FICA Paid	K-1	SE Savings	Audit Risk
$50,000	$7,650	$86,175	$12,120	Higher
$60,000	$9,180	$75,410	$10,590	Moderate
$70,000	$10,710	$64,645	$9,060	Low

The difference between $50,000 and $70,000 is $3,060/year in SE tax savings. The audit risk difference is significant. Most CPAs recommend the middle of the comparable range ($60,000-$65,000 in this case) as the best balance of tax savings and audit defensibility.

Documentation to keep on file:

BLS wage data for the occupation and geographic area
Salary survey printouts (Salary.com, PayScale) for comparable positions
A memo explaining the salary rationale (owner’s duties, hours, experience, comparable range)
The memo should be dated and signed at the beginning of each year
If the business is audited, this documentation is the first thing the IRS asks for
