The “reasonable compensation” requirement is the IRS’s check on S-Corp owners who would otherwise pay themselves $0 salary and take 100% of profits as distributions (avoiding all FICA taxes). The IRS requires that S-Corp shareholders who perform services for the corporation must receive compensation that is “reasonable” for the services they provide. There is no safe harbor, no formula, and no bright-line rule. The IRS uses a facts-and-circumstances test, and the burden of proof falls on the taxpayer if challenged. Getting this wrong in either direction costs money: too low risks IRS reclassification of distributions as wages (plus back taxes, penalties, and interest), while too high unnecessarily increases FICA taxes and reduces the S-Corp’s benefit.

✓Key takeaway

Reasonable compensation factors (from IRS guidance and case law):

The IRS considers:

Training and experience of the shareholder-employee
Duties and responsibilities
Time and effort devoted to the business
Comparable wages for similar positions in similar industries and locations
Dividend history (distributions vs. salary ratio)
Compensation agreements with non-shareholder employees
Use of a formula-based approach (e.g., percentage of revenue)
What comparable businesses pay for similar services
Compensation paid in prior years
The economic condition and profitability of the business

What the IRS looks for (audit triggers):

$0 salary with large distributions (the most common trigger)
Salary significantly below what a replacement employee would cost
Salary that doesn’t increase as the business grows significantly
Salary that’s disproportionately low relative to distributions (e.g., $20,000 salary, $200,000 distributions)

Methods for determining reasonable salary:

Comparable wage data: BLS Occupational Employment Statistics, salary surveys, industry reports, job postings for similar roles in your area
Replacement cost: what would you pay someone to do your job?
Revenue split: some practitioners use 50-60% of net profit as a starting guideline (not an IRS rule)
Independent valuation: a formal reasonable compensation study ($1,000-$5,000) provides the strongest audit defense

The QBI interaction:

Higher salary = lower K-1 = lower QBI deduction
Lower salary = higher K-1 = higher QBI deduction (but more audit risk)
The W-2 wage limitation on QBI means setting salary too low can also LIMIT the QBI deduction (50% of W-2 wages must be at least as high as the QBI deduction)
The optimal salary balances SE tax savings, QBI deduction, and audit risk

What “reasonable” is NOT:

The minimum wage ($7.25-$15/hour depending on state)
Whatever you feel like paying yourself
The amount that minimizes total tax (the IRS specifically rejects this approach)
Zero (if you perform any services for the corporation)

How do you find the right salary number?

Hypothetical example

Round numbers. A single-owner S-Corp operating a plumbing business. Owner does the plumbing work, estimates, scheduling, bookkeeping, and marketing. Net profit: $180,000. The owner works 50 hours per week.

Comparable wage analysis:

Data Source	Position	Salary Range
BLS OES (local area)	Plumber	$50,000-$75,000
BLS OES	Plumber, master/licensed	$65,000-$90,000
BLS OES	Construction manager	$70,000-$100,000
Job postings (local)	Plumbing company manager	$60,000-$85,000
Industry survey	Owner-operator, small plumbing co	$65,000-$95,000

The owner performs multiple roles:

Master plumber (field work): comparable salary $70,000-$90,000
Business manager (estimates, scheduling, admin): comparable salary $50,000-$70,000
But one person can’t earn two full salaries for overlapping hours

Reasonable salary determination:

The owner performs the work of a master plumber ($80,000 midpoint)
Also handles management duties that would otherwise require a part-time office manager ($25,000)
Combined replacement cost: approximately $105,000
But the owner is more efficient (no coordination costs), so a discount is reasonable
Reasonable salary range: $75,000-$95,000
Set at $85,000: defensible, within the comparable range, not aggressive

Tax impact at $85,000 salary:

FICA on salary: $85,000 x 15.3% = $13,005
K-1 distribution: $95,000 ($180,000 - $85,000)
QBI deduction: $95,000 x 20% = $19,000
W-2 wage limit: 50% of $85,000 = $42,500 (exceeds $19,000, so full QBI allowed)
Income tax: approximately $19,300
Total tax: $32,305

If salary were set at $50,000 (too low):

FICA: $50,000 x 15.3% = $7,650
K-1: $130,000
QBI: $130,000 x 20% = $26,000
Income tax: approximately $17,200
Total tax: $24,850
Savings over $85,000 salary: $7,455

But if audited at $50,000:

IRS reclassifies $35,000 of distributions as wages ($85,000 - $50,000)
Back FICA: $35,000 x 15.3% = $5,355
Failure to deposit penalty: 10% = $536
Interest: approximately $500
Total IRS assessment: approximately $6,391
Plus: professional fees to defend ($2,000-$5,000)
Net cost of aggressive salary: potentially MORE than the $7,455 “saved”

The optimal salary is the one that’s defensible AND produces the best tax result. For this plumber, $85,000 is defensible. $50,000 is not. $95,000 is safe but leaves money on the table.
