Defending Reasonable Compensation: How to Document Your S-Corp Salary If the IRS Questions It
The IRS requires S-Corp shareholder-employees to pay themselves a “reasonable salary” before taking distributions. If the salary is too low, the IRS can reclassify distributions as wages, assessing FICA (employer and employee shares), penalties, and interest retroactively. The question is always: what is “reasonable”? There’s no bright-line rule, no published percentage, and no safe harbor. The answer depends on a facts-and-circumstances analysis that weighs multiple factors.
Reasonable compensation defense framework:
IRS factors for determining reasonable compensation:
- Training and experience of the employee
- Duties and responsibilities
- Time and effort devoted to the business
- Dividend history (consistently high distributions with no salary is a red flag)
- Payments to non-shareholder employees for similar services
- Timing and manner of paying bonuses
- What comparable businesses pay for similar services
- Compensation agreements
- Use of a formula to determine compensation
Data sources for benchmarking:
- BLS Occupational Employment and Wage Statistics: Median and percentile wages for specific occupations by metropolitan area. Free, publicly available, and the most commonly cited source.
- Industry salary surveys: Robert Half, PayScale, Glassdoor, and industry-specific surveys.
- Job postings: Current job listings for comparable positions in the same market.
- RCReports or similar services: Automated reasonable compensation studies that compile BLS data, hours worked, and industry factors into a defensible report.
Documentation package (create annually, keep on file):
- Written job description listing all duties performed by the shareholder-employee
- Time allocation (percentage of time spent on each duty category: production, management, sales, admin)
- BLS data for each duty category, weighted by time allocation
- Adjustment for geographic location, business size, and experience
- Comparable salary range and the chosen salary within that range (with explanation for the position within the range)
- Board resolution or shareholder agreement establishing the salary

How does the qualified business income deduction work with S-Corp income?
S-Corp owners may qualify for the Section 199A deduction of up to 20% of qualified business income (QBI), which reduces taxable income but not self-employment tax. The deduction phases out for specified service trades or businesses (SSTBs) when taxable income exceeds $191,950 (single) or $383,900 (married filing jointly) for 2024. For non-SSTB businesses above the income threshold, the deduction is limited to the greater of 50% of W-2 wages paid or 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property. This means the W-2 salary an S-Corp pays its owner directly affects the maximum QBI deduction. Setting compensation too low can actually reduce the QBI deduction, partially offsetting the FICA savings.
Can I change my entity structure after I’ve already started operating?
Yes, but timing and method matter. Converting from a sole proprietorship to an LLC is straightforward and can happen at any time by filing articles of organization with your state. Electing S-Corp status requires filing Form 2553 within 2 months and 15 days of the start of the tax year you want it to take effect. Late elections are available under Revenue Procedure 2013-30 if you can demonstrate reasonable cause. Converting from an S-Corp to a C-Corp or vice versa has additional tax consequences, including potential built-in gains tax, so the timing should be planned with a tax advisor.
