Reasonable Compensation: How to Set Your S-Corp Salary Without Triggering an IRS Audit
Setting your S-Corp salary too low saves payroll taxes today and invites an IRS reclassification tomorrow. Here is how to find the number that is defensible and optimized.
What Reasonable Compensation Means
Reasonable compensation is the amount ordinarily paid for similar services by similar enterprises under similar circumstances. Under IRC Section 162(a)(1), every S-Corp owner who performs services must receive compensation before any distributions. The IRS can reclassify distributions as wages, assess back payroll taxes, interest, and penalties under IRC Section 6662.
How the IRS Evaluates Reasonable Compensation
The IRS considers: Training and experience -- qualifications, education, years of experience. Duties and responsibilities -- every function you perform. Time and effort -- hours per week. Comparable salaries -- BLS data, Robert Half, Glassdoor benchmarks. Business performance -- paying yourself $50,000 on a business netting $600,000 is not reasonable. Distribution history -- the ratio of salary to total compensation is a reasonableness indicator.
The Real Cost of Setting Salary Too Low
An S-Corp owner netting $400,000 who pays $40,000 salary and takes $360,000 in distributions saves roughly $45,000 in FICA. But if the IRS reclassifies $150,000 of distributions as wages, back payroll taxes are roughly $23,000, plus interest (~8%/year) and a potential 20% accuracy penalty. Total assessment can easily exceed $35,000 for a single year, and the IRS can go back three to six years.
How to Determine Your Reasonable Compensation
Step 1: Define your roles -- CEO, salesperson, project manager, bookkeeper. Step 2: Research comparable salaries from BLS.gov, Robert Half, Glassdoor at the 50th-75th percentile. Step 3: Adjust for business size and profitability. Step 4: Document the analysis in a reasonable compensation report. Step 5: Model total tax impact including FICA, QBI deduction, and retirement plan effects.
How It Interacts with the QBI Deduction
Your salary reduces QBI (lowering the 20% deduction) but increases W-2 wages (raising the deduction cap for taxpayers above the threshold). For most S-Corp owners earning $300,000-$500,000, the optimal salary is 10%-30% higher than the minimum defensible number because the QBI wage limitation claws back some FICA savings at very low salary levels.
Common Benchmarks by Profession
Medical/dental practices: $200,000-$400,000. Law firms: $150,000-$300,000. Consulting: $120,000-$250,000. E-commerce: $80,000-$180,000. Construction/trades: $90,000-$200,000. Real estate brokerage: $80,000-$180,000. These assume the owner is active in the business.
Key Takeaways
- Every S-Corp owner performing services must receive reasonable compensation before distributions.
- The IRS evaluates based on training, duties, time, comparable salaries, profitability, and distribution history.
- Setting salary too low risks reclassification, back taxes, interest, and penalties exceeding the FICA savings.
- The optimal salary minimizes total tax after FICA, income tax, QBI, and retirement plan effects.
- Document your analysis annually with a reasonable compensation report.
Frequently Asked Questions
What happens if I do not pay myself a salary from my S-Corp?
The IRS can reclassify distributions as wages, assess back FICA taxes on both employer and employee shares, and impose accuracy-related penalties. In severe cases, the IRS may challenge your S-Corp election.
Is there a safe harbor percentage for S-Corp salary?
No. There is no official IRS safe harbor percentage. The common 60/40 or 50/50 myths are not reliable. Reasonable compensation is a factual determination based on comparables and duties.
How does my S-Corp salary affect retirement plan contributions?
401(k) deferrals, profit-sharing, and defined benefit contributions are all based on W-2 compensation. A $100,000 salary caps profit-sharing at $25,000, while $200,000 allows up to $50,000.
Can the IRS audit my reasonable compensation?
Yes, and it is one of the most common S-Corp audit issues. Officer compensation is a specific line item on Form 1120-S, and a low amount relative to business income is a known trigger.
Should I get a formal reasonable compensation study?
We recommend it for any S-Corp owner earning over $150,000 in pass-through income. The cost is typically a few hundred dollars and is deductible as a business expense.
