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

What the election is actually worth

A sole proprietor with $150,000 of net profit pays self-employment tax on 92.35% of it:

150,000 x 0.9235 x 15.3% = $21,194

Elect S-corporation status, pay yourself a $90,000 salary and take the remaining $60,000 as a distribution, and payroll tax applies only to the salary:

90,000 x 15.3% = $13,770

	Sole proprietor	S-corp
Payroll / SE tax	$21,194	$13,770
Saving		$7,424
Less payroll and filing costs (~$2,000)
Net benefit		~$5,424

That is the whole mechanism, and it is entirely legitimate. The risk is not the strategy — it is setting the salary too low.

The wage base changes the math above $184,500

Social Security tax (12.4% of the 15.3%) applies only to the first $184,500 of wages in 2026. Above that, only the 2.9% Medicare portion continues.

This means the saving per dollar shifted from salary to distribution drops sharply once your reasonable salary approaches the wage base. Below it you save 15.3 cents on the dollar; above it you save 2.9 cents, plus 0.9% more if you are over the additional Medicare threshold.

Practical consequence: the S-corp election is most valuable for profits roughly between $80,000 and $250,000. Below that, payroll and compliance costs eat the benefit. Far above it, most of the income is already past the wage base and the saving is thin relative to the administrative burden.

What "reasonable" means to the IRS

There is no safe-harbour percentage. The frequently cited 60/40 split is convention, not law, and it will not defend an audit on its own. The IRS weighs:

• Training and experience — what your qualifications command.
• Duties and responsibilities — how central you are to producing revenue.
• Time devoted — full-time owner-operators cannot justify a token salary.
• What comparable businesses pay for similar work.
• Payments to non-owner employees — paying a manager more than yourself invites scrutiny.
• Dividend history and the relationship between salary and distributions.

The single strongest defence is documentation: written evidence of comparable market salaries for your role, gathered before you set the number, retained with your corporate records.

How it goes wrong

The failure mode is not subtle. An owner takes a $25,000 salary on $200,000 of profit, the IRS reclassifies distributions as wages, and the result is back payroll taxes, interest, and accuracy-related penalties — typically 20% of the underpayment. Reclassification cases are among the most consistently IRS-favourable in tax court, because the facts are usually obvious.

Warning signs that a salary is indefensible:

• It falls below what you would have to pay someone else to do your job.
• It is a round fraction of profit that moves with profit rather than with the work performed.
• It is below the wage you paid yourself as a sole proprietor doing identical work.
• Distributions substantially exceed salary while you work full time.

Costs to weigh against the saving

• Payroll processing — $500 to $1,500 a year.
• Form 1120-S preparation — $800 to $2,000, above your personal return.
• State franchise or minimum taxes — California, for instance, imposes a minimum franchise tax regardless of profit.
• Unemployment insurance on your own wages in most states.
• Retirement plan interaction — a solo 401(k) employer contribution is calculated on W-2 wages, so a lower salary lowers the ceiling on tax-deferred savings. Cutting salary to save 15.3% can cost more in lost contribution room.
