S-Corp Reasonable Compensation: How to Set It Right
Reasonable comp is what the IRS audits most on S-corps. Here's the actual benchmarking method, the documentation that holds up, and what happens when you set it wrong.

TLDR
Reasonable compensation is the salary an S-corp owner pays themselves as a W-2 employee — and it’s the number the IRS audits most on small S-corp returns.
Set it too low and you trigger an audit + payroll-tax assessment.
Set it too high and you overpay self-employment tax. The right number is benchmarked against industry-specific wage data (BLS, market surveys, comparable practice data), adjusted for your specific role and geography, and documented in a written memo before the first paycheck runs.
In this guide, you’ll learn:
- Understand why reasonable comp is the single most-audited number on small S-corp returns
- See the three legitimate benchmarking sources — BLS, industry surveys, RCReports — and when to use each
- Walk through the five-step method for setting your defensible number
- Get industry-specific comp ranges at typical net income levels (medical, real estate, SaaS, legal, dental, marketing)
- Understand the asymmetric cost — too-low triggers catastrophe, too-high leaks ~$2,300/yr on $30K of over-payment
#Why reasonable comp matters
The S-corp election’s entire tax benefit comes from one mechanism: dividing your net business income into a salary portion (subject to FICA payroll tax — same effective rate as SE tax) and a distribution portion (no SE tax, no FICA). The bigger the gap between net income and salary, the bigger the savings.
That math creates an obvious incentive — pay yourself the smallest possible salary, take everything else as distribution. The IRS knows this and has been auditing S-corp reasonable comp aggressively since the early 2010s. The penalty for getting it wrong isn’t just back taxes; it’s payroll-tax assessment + interest + penalties on the underpayment.
The IRS doesn’t publish a magic number. They use a “facts and circumstances” test — a real person doing real work for the business should be paid what a comparable hire from outside would be paid for the same role.
#The benchmarking method
There are three legitimate sources of comparison data:
1. Bureau of Labor Statistics (BLS) Occupational Employment Statistics. Free, comprehensive, broken down by metro area + industry + occupation. For a solo medical contractor in San Antonio, you can pull median wages for “Physicians and Surgeons, General Internal Medicine” + Bexar County. This is the floor of acceptable evidence.
2. Industry-specific compensation surveys. Trade associations publish them — ADA Survey of Dental Practice, AAA salary surveys, AICPA accounting-firm comp data. More expensive but more defensible because they reflect actual practice-owner compensation, not the broader job-market wage.
3. RCReports or similar specialized vendors. These are services that build reasonable-comp documentation tailored to your facts (entity type, owner role, geographic location, hours worked). They’re the gold standard for audit defense because the methodology is documented from start to finish.
For most ETS clients, we use a combination: BLS as the baseline floor, industry-specific surveys where applicable, and we write the documentation memo in-house with citations.
#How to set the number
The defensible five-step method
- Step 1
Identify the role
What does the owner actually do? A solo consultant who's the only revenue-generator is doing senior-consultant work. A practice owner who sees patients, manages staff, and does business development is doing three jobs.
- Step 2
Pull comparable wage data
BLS median for that occupation in that metro. If multiple roles, weight by time spent.
- Step 3
Adjust for facts
Hours worked (full- vs part-time), experience level, business size (smaller business = smaller comp typically), seasonality.
- Step 4
Compare to net income
Compute reasonable comp as a percentage of net business income. 40–70% is a defensible range. Under 30% or over 80% — recheck the math.
- Step 5
Document before the first paycheck
Write a memo before payroll runs. Include the role description, the comparable wage data with sources, the adjustments made, and the resulting number. Keep it in your business records.
The honest method:
Step 1: Identify the role. What does the owner actually do? A solo consultant who’s also the only revenue-generator is doing the work of a senior consultant. A practice owner who sees patients + manages staff + does business development is doing three jobs.
Step 2: Pull comparable wage data. BLS median for that occupation in that metro. If multiple roles, weight by time spent.
Step 3: Adjust for facts. Hours worked (full-time vs. part-time), experience level (seniority adjustment), business size (smaller business = smaller comp typically), seasonality.
Step 4: Compare to net income. Compute what reasonable comp would be as a percentage of net business income. If it’s 40-70%, you’re in a defensible range. If it’s under 30% or over 80%, recheck the math.
Step 5: Document. Write a memo before the first paycheck runs. Include the role description, the comparable wage data with sources, the adjustments made, and the resulting comp number. Keep it in your business records (Basecamp portal works).
#Examples by industry
These are illustrative ranges based on typical ETS engagements — not advice for your specific situation.
| Industry / role | Net income | Typical reasonable comp range |
|---|---|---|
| Solo 1099 medical contractor | $250K | $130K–$165K |
| Real estate agent (top producer) | $400K | $135K–$185K |
| SaaS founder (operator-led) | $500K | $150K–$220K |
| Solo attorney (boutique practice) | $480K | $165K–$220K |
| Construction owner-op (Texas) | $300K | $95K–$135K |
| Marketing agency founder (solo) | $640K | $175K–$240K |
| Dental practice owner | $750K | $190K–$280K |
These ranges reflect facts-and-circumstances analysis. Some owners legitimately fall outside the range (specialty professional services often higher; passive owner-operators sometimes lower). Documentation is what makes the position defensible.
#What happens when you set it wrong
Too low: The IRS reclassifies a portion of your distributions as salary. You owe back FICA (15.3%) + interest + penalties on the reclassified amount. For an owner who took $300K in distributions instead of paying themselves a $150K salary, that’s roughly $23K of additional tax + interest + penalties — potentially over multiple years.
Too high: You overpay payroll tax annually. Real cost: roughly 7.65% of the over-payment amount (employer + employee FICA on what should have been distribution). For a $30K over-payment, that’s ~$2,300/yr leaked unnecessarily.
The asymmetry matters: under-payment is catastrophic; over-payment is annoying. When in doubt, set comp slightly higher than the floor and document the upper-end rationale.
#When to revisit
Reasonable comp isn’t set once. Revisit annually:
- Major income change (revenue up 50%+ or down 30%+)
- Role change (added staff, hired a manager, shifted from operator to owner)
- Geographic move (cost-of-living + market-rate change)
- Industry shift (changed specialties, added new service line)
- External event (acquisition offer in progress — comp affects valuation)
Most ETS retainer clients re-benchmark every January as part of the year-ahead planning session.
#Common questions
Can I pay myself differently in different years? Yes. Reasonable comp is reset annually based on each year’s facts. A bad year reduces the comp; a great year raises it.
What if I don’t run payroll at all and take only distributions? This is the single most-audited S-corp structure. The IRS routinely reclassifies the entire distribution as wages — meaning you pay FICA on 100% instead of on the salary portion only. Don’t do this.
Can I pay reasonable comp annually instead of monthly? Technically yes, but it raises audit risk. We recommend monthly or semi-monthly payroll runs through Gusto so the comp looks like normal employment.
Do I have to register for state payroll tax to pay myself? Yes. In every state. Even if you’re a one-person S-corp, you need state unemployment insurance registration. Gusto handles this during setup.
What about reasonable comp for spouse-owners or family members on payroll? Same standard applies. If your spouse is on payroll, their comp has to reflect real work + market wage. Putting your 7-year-old “on payroll” for $12K to claim a business deduction is a well-documented IRS audit trigger.
If you’re running an S-corp and reasonable comp hasn’t been formally benchmarked, the Discovery call is the right next step. We model the right number against industry data and write the documentation memo as part of the engagement.
