Underpay your S-corp salary and the IRS can reclassify your distributions as wages: back FICA, plus interest, plus a penalty. A typical reclassification audit runs $20K–$60K. If you elect S-corp status, the IRS requires you to pay yourself a "reasonable" W-2 salary before taking distributions.
The catch: "reasonable" isn't defined in the Code. It's a facts-and-circumstances test. Here's how the IRS and the Tax Court apply it.
Why the IRS cares
S-corp distributions don't pay FICA (15.3%). Salary does. So an owner has every incentive to underpay themselves and over-distribute. The IRS knows this. Audits of S-corps with under-market salaries are a steady revenue source for the agency.
When the IRS reclassifies, the owner owes:
- Back FICA on the reclassified portion (15.3%)
- Penalties (often 20% of the back tax)
- Interest from the original due date
- Failure-to-deposit penalties on the unpaid payroll tax
A typical reclassification audit costs the owner $20K–$60K in back tax + penalties for a few years of underpayment.
The factors the IRS uses
From the IRS S-Corp Compensation Job Aid and from cases like Watson v. Commissioner (8th Cir. 2012):
- Training and experience of the owner-employee
- Duties and responsibilities: what you actually do day-to-day
- Time and effort devoted to the business
- Dividend history: large distributions with small wages = red flag
- Payments to non-shareholder employees: what you pay others doing similar work
- Timing and manner of payments: sporadic or formula-based
- What comparable businesses pay for similar services
- Compensation agreements: written employment contract
- Use of a formula (e.g., a percentage tied to revenue)
No single factor is dispositive. Courts weigh them together.
Three approaches to setting the number
Approach 1: Market-comp study
Hire a CPA or use a service (RCReports, Salary.com data) to pull market comp data for your role and geography. Document the result. Cost: $250–$1,000.
This is the gold-standard defense. If audited, you hand the auditor the report and the conversation usually ends.
Approach 2: 60/40 heuristic
60% of net profit as salary, 40% as distribution. Common rule of thumb but not an IRS-blessed safe harbor.
Works in many cases. Fails when net profit is heavily skewed by a one-time event (large contract win, asset sale). Then 60% of profit overpays salary by a lot.
Approach 3: Cost-replacement
What would you pay an outside contractor to do your job? That's your salary. If you're a software developer billing $150/hr × 1,500 hours = $225K/yr, your salary should be in that range.
Best for service businesses where market comp is well-documented.
Common ranges by role (rough)
These are illustrative, not advice. Real numbers depend on geography, experience, and specifics.
| Role | Typical reasonable salary range |
|---|---|
| Solo software consultant (mid-career) | $100K–$180K |
| Solo design / marketing consultant | $70K–$140K |
| Solo law / accounting practice | $90K–$200K |
| Solo coach / educator | $50K–$120K |
| Solo trades (general contractor) | $60K–$130K |
| E-commerce owner-operator | $40K–$90K (lower because more work is "owner" not "operator") |
If your salary is below the bottom of the relevant range and the rest is distribution, you're in dangerous territory.
The "no profit" defense
If the S-corp had little or no profit, the IRS generally won't reclassify zero distributions as wages. You can pay yourself a low or zero salary in a money-losing year.
But: if the IRS sees small wages and large distributions, the loss-year defense doesn't apply.
What "reasonable" doesn't mean
- It doesn't mean "what you can afford." If the business is wildly profitable, your salary should reflect the value of your labor, not just enough to scrape by.
- It doesn't mean "the same every year." Salaries can adjust with the business and with market rates.
- It doesn't mean "based on hours." A high-skill professional working 20 hours/week may legitimately earn more than a low-skill professional working 60 hours/week.
- It doesn't mean "exactly market median." A range exists; you can defend something in the bottom quartile if other factors support it.
Documentation that holds up
If audited, the auditor wants:
- Written compensation agreement between you and the corporation (board minutes or a written consent)
- Comp study or market analysis supporting the number
- Payroll records showing actual W-2 issuance, FICA paid, withholding remitted
- Distribution log showing distributions taken in addition to salary
- Job description for what you actually do
Most owner-operators skip 1, 2, and 5, then scramble during the audit.
What ExpenseGhost helps with
Reasonable comp isn't a number you set once. Profit moves, and a salary that looked defensible in January can look thin by October. ExpenseGhost keeps your running profit current, with every transaction categorized and the receipts behind it, so when you and your CPA revisit the number, the inputs are real instead of reconstructed. It won't replace a market-comp study; it makes sure the books behind one are done. See the tax dashboard.

FAQ
Can I take zero salary in a startup year?
Yes, if the business is genuinely losing money. Many CPAs will support a very low salary in your first year while you ramp. Once profits exist, salary should follow.
What if I have a side W-2 job?
Your S-corp salary is independent of your other employment. The S-corp must pay reasonable comp for the services you provide to it, regardless of other jobs.
What if I work part-time on the S-corp?
Salary should reflect time committed. A 10-hours/week S-corp consultancy can defend a much lower annual salary than a 50-hours/week one, if you can document the hours.
Can the IRS recharacterize distributions years later?
Yes. The reclassification statute of limitations is generally 3 years from the return due date, but it extends to 6 years if more than 25% of gross income is omitted. Pay enough salary now; it's much cheaper than back-FICA later.
What about my S-corp 401(k) contributions?
Employee deferral comes out of W-2 salary. Employer contribution is up to 25% of W-2 salary. If you keep salary very low to minimize FICA, you also kill your retirement contribution capacity.
