S-Corp Reasonable Comp: The IRS Factors, Case Law, and Defensible Benchmarks

#Why “reasonable” is judged on nine factors

The reasonable compensation rule comes from IRC §162(a)(1), which lets a business deduct “a reasonable allowance for salaries or other compensation for personal services actually rendered.” The word “reasonable” carries the audit weight. Treasury regulations and 50+ years of court decisions have built out what reasonable means in practice.

For C-corps, the case law focused on excessive comp — examiners challenged owners who paid themselves too much to disguise dividends as deductible wages. For S-corps, the case law flipped — examiners now challenge owners who pay themselves too little to disguise wages as non-FICA-bearing distributions. The factors are the same; the direction of the challenge is reversed.

The nine factors below are synthesized from Treas. Reg. §1.162-7(b)(3), Mayson Manufacturing Co. v. Commissioner (6th Cir. 1949), Elliotts, Inc. v. Commissioner (9th Cir. 1983), and the modern S-corp owner-comp cases. The IRS Job Aid on Reasonable Compensation for S Corporation Owners (2008, periodically updated) cites essentially this same framework.

#Factor 1 — The employee’s role and the nature of the duties performed

What does the owner actually do? A solo physician seeing patients full-time is doing one job: medical practice. A practice owner who sees patients plus manages five staff plus does business development is doing three jobs.

The reasonable comp number scales with the breadth and depth of the role. An owner doing the work of two professionals + administrative management deserves higher comp than one performing a single function.

What gets documented: A written job description listing daily, weekly, and monthly responsibilities. Hours per week per function. Decision authority. Direct reports.

#Factor 2 — The employee’s background, education, experience, and credentials

A first-year practitioner doesn’t make what a 20-year veteran makes. A board-certified specialist doesn’t make what a generalist makes. An owner with an MBA and 15 years in operations doesn’t make what an entry-level manager makes.

Credentials matter not because the IRS values degrees per se, but because the open-market wage data the IRS will compare against is segmented by experience and credentials.

What gets documented: Resume / CV in company records. Professional certifications. Years of experience in role and adjacent roles. Continuing education completed.

#Factor 3 — The size and complexity of the business

A solo S-corp doing $250K in revenue with no staff has different reasonable comp than the same owner running a 20-person firm doing $5M in revenue. Larger businesses, more complexity, more management overhead, higher comp.

The complexity dimension is important — a business with multiple lines, regulated activities, international operations, or significant inventory deserves higher management comp than a single-product service business.

What gets documented: Annual revenue, number of employees, number of locations, business activities (single vs. multi-line), regulatory environment.

#Factor 4 — The company’s economic performance

Reasonable comp scales with what the business can actually pay. An S-corp generating $80K of net business income can’t justify $150K of reasonable comp — the owner would be paying themselves more than the business earns.

Conversely, an S-corp generating $1.5M of net business income with a single owner doing all the work would struggle to justify $80K of comp — the gap between income and reasonable comp is too wide.

What gets documented: Multi-year P&L showing revenue, gross margin, operating expenses, net income before owner comp. Industry growth rate context if rapid expansion or contraction is happening.

#Factor 5 — The company’s compensation policy for all employees

How does the owner’s comp compare to other employees in the business? If a non-owner manager earns $90K and the owner-CEO earns $80K, there’s an inverted comp structure problem. The owner should earn at or above what the highest-paid non-owner employee earns (with adjustments for role differences).

For solo S-corps with no employees, this factor doesn’t apply directly — but the absence of internal comparison data shifts more weight to external benchmarks (Factor 9).

What gets documented: Comp schedule for all employees, including non-owners. Any equity, bonus, or profit-sharing programs.

#Factor 6 — The comparable compensation of similar businesses’ similar employees

This is where external benchmarking enters. For a solo dental practice owner in San Antonio, the IRS will compare against published dentist comp in San Antonio, Bexar County, or Texas — depending on the data available. The closer the match (geography + industry + role + experience), the more persuasive the comparison.

Three legitimate data sources:

• Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics — free, comprehensive, broken down by metro area + occupation
• Industry-specific compensation surveys — ADA Survey of Dental Practice, AICPA Management of an Accounting Practice survey, ASA Society of Actuaries comp surveys, etc.
• Commercial reasonable comp services — RCReports, Salary.com Pro, similar — these blend BLS + survey data + custom factors

For audit defense, all three sources improve the position. Single-source benchmarks (BLS only) work for clean cases; multi-source documentation is required for higher-stakes positions.

What gets documented: The benchmarking data with sources, dates, parameters used, and the resulting reasonable comp range.

#Factor 7 — The compensation history of the employee

Has the owner’s comp tracked logically with role and revenue growth over time, or does it jump around? Random year-over-year changes in comp without corresponding role or business changes invite scrutiny.

The defensible pattern is gradual growth as revenue and complexity scale, with documented adjustments tied to events (new credentials, expanded role, business growth milestones).

What gets documented: Multi-year comp history. Explanations for any significant year-over-year changes.

#Factor 8 — Distributions vs. compensation pattern

This is the S-corp-specific factor. How does the salary/distribution split look year over year? An owner taking $40K in salary and $200K in distributions year after year, with no underlying reasonable comp documentation, is the audit-bait pattern.

The IRS is looking for a coherent story: reasonable comp set by external benchmarks (Factor 6), paid on a regular payroll cadence, with distributions following business earnings rather than the payroll calendar. A 25/75 salary/distribution split can be defensible with the right facts; a 5/95 split is rarely defensible regardless of facts.

What gets documented: Multi-year payroll records showing salary cadence and amounts. Distribution records showing timing and amounts. Distribution policy adopted by the board.

#Factor 9 — Independent investor return / dividend equivalence

The Elliotts test asks: would an independent investor in this business be satisfied with the rate of return on equity after paying the owner this comp? If the comp is so high that there’s no meaningful return left, the comp is too high. If the comp is so low that there’s a windfall return, the comp is too low.

For S-corp owner-comp cases, this factor cuts against under-compensation. If the owner is generating $500K of net income and taking $50K of salary, leaving $450K of “return on equity” that’s really compensation for services rendered, an independent investor wouldn’t see that — they’d see the owner being underpaid and the distribution being effectively wages.

What gets documented: Owner’s capital invested. Return on equity calculation. Industry-typical investor return expectations for this type of business.

#The court cases that built the modern framework

#Watson v. United States (2010, 2012 8th Cir.)

The keystone modern S-corp reasonable comp case. David Watson was a 100% owner CPA who paid himself $24,000 in salary and took $375,000 in distributions for 2002. The IRS reclassified $67,044 of distributions as wages (raising effective salary to $91,044) and assessed back FICA + penalties.

The 8th Circuit affirmed the reclassification, holding that Watson’s $24,000 salary was below what an “independent investor would pay for similar services.” The court accepted the IRS’s benchmark of $91,044 based on industry comp data for CPAs in the relevant market.

Practical takeaway: A roughly 4x distribution-to-salary ratio with no documented benchmarking is unlikely to survive audit. The Watson case is cited in essentially every modern S-corp reasonable comp examination.

#Glass Blocks Unlimited v. Commissioner (T.C. Memo 2013-180)

Frederick Blodgett was the sole shareholder of Glass Blocks Unlimited. For 2007–2008, he took $0 salary and full distributions. The Tax Court reclassified the distributions as wages.

Practical takeaway: $0 reasonable comp is the cleanest possible loss. The IRS doesn’t even need to argue the benchmark — any reasonable comp greater than $0 is a defensible reclassification target.

#McAlary v. Commissioner (T.C. Memo 2013-219)

Sean McAlary was a real estate broker operating through an S-corp. He paid himself $24,000 in salary and took ~$240,000 in distributions. The court accepted the IRS’s reclassification to approximately $83,000 in wages based on BLS data for real estate brokers in his market.

Practical takeaway: Real estate brokers and similar commission-based service providers cannot avoid the reasonable comp rules by characterizing comp as “broker commissions” or similar — if the owner does the work, the comp is wages.

#Davis v. Commissioner (T.C. Memo 2012-184)

Allen Davis was a CFP financial advisor who paid himself $24,000 salary and took $109,000 in distributions. The court reclassified $109,000 to approximately $75,000 in wages.

Practical takeaway: Even mid-range income levels ($100K–$200K of net business income) get scrutinized for under-compensation when the salary/distribution ratio is extreme.

#Spicer Accounting v. United States (9th Cir. 1990) and Joly v. Commissioner (T.C. Memo 1998-361)

Earlier cases that established the framework before the modern S-corp era. Cited frequently as foundational precedent on the principle that owner services must be compensated as wages when the underlying facts show employment.

#What the modern audit looks like

When the IRS opens a reasonable comp examination, the standard request list:

1. Multi-year W-2s for the shareholder-employee
2. Multi-year 1120-S returns and K-1s
3. Multi-year personal 1040 returns
4. Distribution records by date and amount
5. Time records / job description for the shareholder-employee
6. Comp records for all employees of the corporation
7. The reasonable comp benchmarking analysis and source documentation
8. Industry comparison data the corporation used
9. Board resolutions on comp policy
10. Any payroll service provider records

The examiner then runs the nine-factor analysis and compares the corporation’s documented comp to the IRS’s reconstructed benchmark. If the gap exceeds 15–20%, expect a reclassification proposal.

#The math of a reclassification

For an owner taking $40K salary and $200K distributions where the IRS reconstructs reasonable comp at $90K, the reclassification math:

• Wages reclassified: $50,000
• Additional employee FICA: $50,000 × 7.65% = $3,825
• Additional employer FICA: $50,000 × 7.65% = $3,825
• Total additional FICA: $7,650
• Federal income tax adjustment: minimal (W-2 and K-1 both flow to personal return)
• Plus interest: 6–8% annual, accruing from the original due date
• Plus accuracy-related penalty (20%): potentially $1,530

For a single year, the cost is ~$10,000. For a 3-year audit, ~$30,000. For a 5-year audit (with extended statute), $50,000+. Plus the cost of defending the audit (typically $5,000–$15,000 in professional fees).

The cost of getting reasonable comp wrong materially exceeds the savings from setting it low.

#How to set comp that survives all nine factors

Practical workflow:

1. Identify the role. Write the job description. Estimate hours per function.
2. Document credentials. Resume, certifications, years of experience.
3. Quantify business performance and complexity. Multi-year P&L summary, employee count, business activities.
4. Pull external comp benchmarks. BLS as floor, industry surveys, RCReports if budget allows.
5. Test against internal comparisons. Compare to non-owner employee comp.
6. Compute Elliotts independent-investor test. Does the post-comp profit support a reasonable return on equity?
7. Set the number in the upper half of the defensible range for audit-defense purposes (not the lowest possible number).
8. Document everything in a written memo signed by the owner before the first paycheck runs.
9. Re-benchmark annually with updates for changed circumstances.
10. Pay on regular cadence (monthly or semi-monthly) consistent with the memo.

#Industry-specific benchmarks at typical income levels

These ranges are illustrative based on ETS engagement patterns — your specific number depends on the nine-factor analysis above.

Industry / role	Net business income	Defensible reasonable comp range
Solo physician — primary care contractor	$300K	$160K–$200K
Solo physician — specialist contractor	$500K	$245K–$310K
Solo attorney — litigation	$400K	$145K–$195K
Solo attorney — transactional	$550K	$175K–$235K
Solo dental practice owner	$750K	$200K–$285K
Real estate broker — top producer	$400K	$135K–$195K
SaaS founder (technical, operator-led)	$500K	$155K–$225K
Marketing agency founder (solo)	$640K	$185K–$255K
Construction owner-operator (TX)	$300K	$90K–$130K
CPA firm owner (solo)	$400K	$140K–$200K
Trucking owner-operator	$250K	$75K–$110K
1099 IT consultant (senior)	$280K	$135K–$185K

These ranges represent the middle 60% of the defensible spectrum. Owners with stronger credentials, larger operations, or above-market geography may exceed the upper end legitimately; owners with newer credentials or below-market geography may justify the lower end.

#Common questions

Does the IRS ever publish acceptable reasonable comp percentages or ratios? No. There’s no “60% of net income” or “$X per hour” published rule. The framework is facts-and-circumstances under the nine factors, with case law providing applied examples.

What if my business is genuinely seasonal or volatile? Reasonable comp can be set as an annual amount paid evenly across the year, even if income is concentrated in certain months. The IRS expects regular payroll cadence — not for income to be paid out as it comes in. Annual adjustments based on actual full-year results are appropriate.

Can I pay myself reasonable comp once a year as a single lump sum? This is technically allowed but flags audit risk. The IRS looks for regular payroll cadence as one of the markers of compensation vs. distribution. Annual lump-sum “reasonable comp” payments look like backfilled tax planning rather than employment.

Does the IRS challenge comp that’s too high? For C-corps, yes (excessive comp gets reclassified as dividend). For S-corps, rarely — the entity is pass-through so there’s no incentive to overpay. The S-corp reasonable comp challenges are almost always under-comp cases.

What if I’m the only employee and I do everything? Then your comp covers all the roles you fill — the executive role, the operational role, the sales role, the customer service role. The reasonable comp number is the sum of the comp for those functions, weighted by time spent.

Can family members be on payroll? Yes, if they perform real work for market-rate compensation. Putting your 8-year-old “on payroll” for $14K to claim a deduction is a documented audit trigger and almost always fails. Spouses doing real administrative or operational work can be properly compensated.

How does the QBI deduction interact with reasonable comp? For non-SSTB pass-through businesses above the QBI thresholds ($241,950 single / $483,900 MFJ for 2026), the QBI deduction is limited by W-2 wages. Higher reasonable comp = higher W-2 wages = potentially higher QBI deduction. The interaction can make slightly-higher-than-minimum comp the right move. We model this explicitly during planning.

What if my industry doesn’t have published BLS data? Use the closest BLS category as the floor, supplement with industry survey data, and explain the adjustment in the documentation memo. Niche industries (specialty consulting, emerging tech roles, etc.) often require multiple data sources blended.

How do I document hours worked if I don’t keep a timesheet? Reconstruct from records you do keep — calendar, email volume, billing records, client meeting logs. The IRS doesn’t require formal timesheets but does want some basis for the hours estimate.

What’s the statute of limitations on reasonable comp examinations? The standard 3-year statute applies under §6501(a). Substantial understatement (>25% of gross income omitted) extends to 6 years. Fraud has no statute. Most reasonable comp audits are 1–3 year scopes.

If you’re running an S-corp and reasonable comp hasn’t been benchmarked against the nine factors — or if your current number was set by “what saves the most tax” rather than “what holds up under examination” — the Discovery call is the right next step. We benchmark, document, and structure comp to survive both audit and audit-defense costs. We don’t do surprises — you’ll see the math and the documentation memo before anything goes into payroll.
