The standard
IRS guidance requires "reasonable compensation for services actually rendered." That's vague on purpose — the IRS wants flexibility to challenge salaries that are obviously low relative to profits.
The factors IRS courts use
From case law (notably Watson v. United States, 2010):
- Training and experience
- Duties and responsibilities
- Time and effort devoted to the business
- Dividend history
- Payments to non-shareholder employees
- Timing and manner of paying bonuses to key people
- What comparable businesses pay for similar services
- Compensation agreements
- The use of a formula to determine compensation
Practical translation: if you're doing $300k of work that an employee would earn $120k to do, your salary should be closer to $120k than $40k.
What "too low" looks like in tax court
The famous Watson case: CPA took $24,000/year salary on $200k+ of S-Corp distributions. Tax court reclassified $91,044 as wages. Result: ~$20,000 in back payroll taxes + penalties.
Modern audit signals:
- Salary less than 25% of distributions
- Salary below the federal poverty line while distributions are substantial
- Salary below what you'd pay a hired hand for the same work
- No salary at all in years with significant distributions
- Salary less than what industry data shows for your role/location
Benchmarks to cite
- Bureau of Labor Statistics (BLS) OES data — bls.gov/oes — median wages by occupation and metro area. Free. Most defensible source.
- Salary.com — good for role-level benchmarks
- Glassdoor / Payscale — supplementary
- RCReports — paid service specializing in reasonable compensation reports for S-Corp owners (~$250/report). What many CPAs use.
Practical salary-setting methods
Method 1: 60/40 split
Pay yourself 60% of net profit as salary, 40% as distribution. Simple, defensible in most situations. Works well at moderate incomes ($80k–$200k).
Method 2: Replacement cost
What would you pay an employee to do everything you do? That's your reasonable salary. If the answer is $90k, pay yourself $90k regardless of profit.
Method 3: Industry benchmark
Look up the median wage for your role in your metro area via BLS. Pay that. Adjust up if you have exceptional experience or the business is highly profitable.
Method 4: Gradient with income
| Net profit | Recommended salary | Distribution |
|---|---|---|
| $80,000 | $45,000–$55,000 | $25,000–$35,000 |
| $150,000 | $75,000–$95,000 | $55,000–$75,000 |
| $250,000 | $100,000–$140,000 | $110,000–$150,000 |
| $500,000 | $150,000–$220,000 | $280,000–$350,000 |
| $1,000,000 | $200,000–$300,000 | $700,000–$800,000 |
Above the Social Security wage base (~$176k), additional salary still costs Medicare (2.9% + 0.9% for high earners), but no more SS. So salary can grow more freely without FICA penalty.
Documentation that protects you
- Written "Reasonable Compensation Study" — even a one-page document citing your salary determination and the BLS data you used
- Time tracking for the year (rough — 40 hrs/wk for 50 weeks = 2,000 hrs of work)
- Written job description of your role
- Comparison data printouts from BLS or RCReports
If audited, pulling this out immediately changes the conversation. If you have nothing, the IRS drives the determination.
Common mistakes
- Zero salary in profitable years. Automatic audit bait.
- Same salary every year regardless of profit. Mildly suspicious.
- Annual salary declared but no actual payroll run. W-2 must be issued via a real payroll system.
- Year-end single-shot salary. The IRS prefers regular payment (monthly, biweekly). One lump payment in December looks constructed.
What an IRS reclassification looks like
Audit opens. You can't justify the salary. The IRS:
- Recalculates what "reasonable" would have been
- Treats the difference (distribution → wage) as underreported wages
- Assesses back FICA (7.65% employer + 7.65% employee on the reclassified amount)
- Adds interest and penalties — often 100% of the tax
- Issues corrected W-2
Example: $50k reclassified from distribution to salary. Back FICA = $7,650. Plus 100% penalty = $15,300 owed. Plus interest.
The safe middle path
For most solopreneur S-Corps with $80k–$250k net profit:
- Pick a salary that's at least what a hired worker would earn (BLS median)
- Run actual payroll monthly or biweekly
- Keep a one-page "reasonable compensation study" documenting your reasoning
- Review annually — adjust if profit shifts significantly
Not worth trying to shave another $3k of SE tax savings by halving your salary. The reclassification risk isn't worth it.
