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 David E. Watson, P.C. v. United States (8th Cir. 2012), where the district court found that $24,000 was not a reasonable salary for an accountant taking about $200,000 a year in distributions and set reasonable pay at $91,044 a year. Setting the salary too low lets the IRS reclassify distributions as wages. 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: what comparable businesses pay for similar services
Payments to non-shareholder employees, bonuses to key people, and compensation agreements
Dividend history (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

No industry ranges: the Code and regulations give no specific guideline or salary range; the number comes from comparable pay for the work the owner actually does.

No percentage rule: Some practitioners use a fixed percentage of S-Corp net income as salary. It has no IRS source: the Code and regulations give no specific guideline for reasonable compensation, so it shouldn’t be the basis for setting salary.

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. For current guidance, see IRS Form 2553 instructions. 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

Illustrative numbers only, not a real client and not advice for your facts.

Is there a salary number that keeps an S-Corp safe?

No. The IRS’s own fact sheet says there are no specific guidelines for reasonable compensation in the Code or the regulations. Courts decide each case on its facts, so no dollar amount, percentage of profit or salary-to-distribution ratio works as a safe harbor.

What the IRS does say is where it looks. The key is what you did for the company, judged by the source of its gross receipts. For a sole-owner plumber with 15 years in the trade who also estimates, markets and keeps the books, that’s the plumbing work and the running of the business. Courts have also weighed training and experience, duties, hours, what comparable businesses pay for similar services, and compensation agreements, among other factors.

If the salary turns out too low, the IRS can reclassify distributions as wages. In Watson, the appeals court said a low salary that doesn’t reflect the real pay for the work is treated much like no salary at all.

What is a single-member LLC and how is it taxed?

A single-member LLC is a legal entity with one owner. The IRS treats it as a disregarded entity by default, meaning it does not file its own return; income and expenses flow directly to Schedule C on the owner’s personal Form 1040. The LLC provides liability protection without adding a separate tax return. Self-employment tax applies to all net income, same as a sole proprietorship. You can elect S-Corp taxation by filing Form 2553, which keeps the LLC legal structure while changing the tax treatment to require a reasonable salary and allowing the remaining profit as a distribution free of FICA. State treatment varies: some states charge an annual LLC fee or franchise tax regardless of federal tax election.
