S-Corp Reasonable Salary: The IRS Rules in Plain English

Why this matters

S-Corp owners can pay themselves in two ways:

• W-2 salary — subject to 15.3% payroll tax (employee + employer FICA)
• Distributions — not subject to FICA, only income tax

The temptation: pay yourself $1 in salary and take everything else as distributions, saving thousands in payroll tax. The IRS knows this. Hence the reasonable compensation rule.

If your salary is "unreasonably low," the IRS can reclassify distributions as wages, hit you with back FICA, penalties, and interest. Audits in this area have surged since 2020.

What "reasonable" actually means

The IRS hasn't published a formula. Instead, they use a list of factors from case law (especially Watson v. Commissioner, 2010):

1. Training and experience — what does someone with your background earn?
2. Duties and responsibilities — what do you actually do day to day?
3. Time and effort — full-time? part-time? side hustle?
4. What comparable businesses pay — industry benchmarks for your role
5. Compensation in past years — sudden drops trigger scrutiny
6. Comparison to non-shareholder employees — are you paid less than employees you supervise?
7. Bonus history — irregular bonuses are okay; replacing salary with them isn't
8. Dividend history — does the S-Corp pay dividends to non-shareholders?
9. Use of independent contractors — comparable contractor rates

Common benchmarks

The IRS doesn't endorse a specific source, but auditors commonly reference:

• BLS Occupational Employment Statistics — bls.gov data by occupation
  • metro area
• Salary.com / Glassdoor / Payscale — commercial salary surveys
• RC Reports / The S Corp Reasonable Compensation Report — paid industry-specific reports many CPAs use

The "60/40 rule" myth

You'll hear that a 60% salary / 40% distribution split is "the safe ratio." This is a myth. The IRS has explicitly stated there is no ratio rule. What matters is whether your salary is reasonable for your role, not what percentage of profit it represents.

A $250K salary in a $200K-profit S-Corp can be unreasonable (low). A $50K salary in a $1M-profit S-Corp can be reasonable (if $50K is the going rate for that work).

Documentation that wins audits

When the IRS audits, the burden is on you. The best defense:

1. Written salary determination — a one-page memo each January citing your role, hours, comparable benchmarks, and the resulting number.
2. Time logs — even rough ones. If you claim to work part-time, the IRS will check whether your distribution is plausible.
3. Industry survey data — print a screenshot of the BLS data you used.
4. Comparable contractor rates — what you'd pay an outside person to do your job.

When the IRS challenges salary

If the IRS reclassifies $50K of distributions as wages:

• You owe ~7.65% employer FICA = $3,825
• You owe ~7.65% employee FICA = $3,825
• You may owe income tax penalties (rare but possible)
• You owe interest from the original due date
• Possible failure-to-deposit penalty (2-15%)

Total exposure on a $50K reclassification: typically $8,000-$12,000.

When NOT to elect S-Corp

The S-Corp election makes sense when payroll tax savings > administrative cost. For solo operators, that's usually around $50,000-$75,000 of net profit. Below that, the savings don't cover:

• Payroll service fees ($500-1,200/year)
• Tax preparation for the corp return
• State franchise taxes (varies)
• The complexity of running actual payroll
