S-Corp Reasonable Salary: What the IRS Actually Looks At (and How to Defend Your Number)
The "pay yourself 40% and take 60% as distributions" rule is not in the tax code. The IRS has never blessed it. In every losing taxpayer case, the owner set salary too low and the IRS reclassified distributions as wages, with penalties.
The Legal Standard
IRC Section 3121 and Treasury Regulation 31.3121(d)-1(b) define reasonable compensation as the amount that would ordinarily be paid for like services by like enterprises under like circumstances. It is a facts-and-circumstances test. There is no statutory percentage.
Rev Rul 74-44 and IRS Fact Sheet FS-2008-25 establish the nine factors the IRS examines when evaluating whether an S-Corp owner's salary is reasonable.
The Nine IRS Factors
The Case Law: What Courts Have Said
The Defensible Methodology
The safest approach to setting reasonable salary: pull BLS OEWS (Bureau of Labor Statistics Occupational Employment and Wage Statistics) data for your specific role and geographic market, apply adjustments for solo operator context (typically 15-25% below median due to absence of management responsibilities), and document the analysis at the start of each year.
RCReports, RoseRyan, and Salary.com provide more detailed comparable-wage analysis services used by CPAs and expert witnesses. For a solo owner handling the analysis themselves, the BLS OEWS database is the acceptable starting point.
Worked Examples
Audit Triggers to Avoid
| Trigger | Why It Flags | Remediation |
|---|---|---|
| Distribution-to-salary ratio above 3:1 | IRS computational screening for S-Corp salary recharacterization | Increase salary or reduce distribution to bring ratio below 3:1 |
| Salary below BLS 25th percentile for comparable role | BLS OEWS is the court-accepted benchmark | Document the analysis and justify any below-median result |
| Salary dropped from prior year without explanation | Suggests responsive to IRS awareness, not arm's-length determination | Document the business reason for any salary reduction |
| No documented compensation analysis | No contemporaneous evidence means the salary looks arbitrary | Create a BLS-sourced analysis at the start of each year; save it |
| Non-cash distributions instead of salary | Red flag that compensation is being structured to avoid payroll | Always pay via payroll for the salary portion |
Documentation Checklist
- Annual compensation analysis document (BLS OEWS source data printed or saved as PDF)
- Comparable wage calculation worksheet (role, geography, solo-operator adjustment, result)
- Board minutes or member resolution adopted at start of year documenting the salary decision
- Year-end reasonableness review (check if salary is still defensible given actual profit)
- Payroll records showing consistent W-2 salary payments throughout the year
- Evidence of actual payroll processing (Form 941, W-2, W-3 on file)
Penalties If the IRS Wins a Reclassification
If the IRS reclassifies S-Corp distributions as wages: employer FICA on the reclassified amount (7.65%), employee FICA grossed up (7.65%), accuracy-related penalty of 20% of the underpayment under IRC Section 6662, plus interest from the original due date. On a $50,000 reclassification, that is approximately $9,600 in FICA plus $1,920 penalty plus 2-3 years of interest.
The downside risk from under-paying salary is asymmetric. The cost of getting the analysis right is a few hours and a BLS OEWS printout.
