    Reasonable Compensation for S-Corp Owners

    TaxKiln Editorial · Last reviewed:

    S-Corp owner-employees must take reasonable compensation for services rendered before distributing profit (Rev. Rul. 74-44). Three IRS-accepted approaches exist: the market approach (comparable wages from BLS OEWS), the cost approach (replacement cost of the owner's labour), and the income approach (independent-investor test). Practitioners typically anchor on the market approach with BLS data, then sanity-check against cost and income methods.

    TaxKiln framework

    BLS-Anchored Reasonable Compensation Framework

    TaxKiln's multi-factor framework for S-corp owner reasonable compensation under Rev. Rul. 74-44: BLS Occupational Employment and Wage Statistics (OEWS) median anchor + 10th/90th percentile band, recentered by regional cost-of-labor index, hours-of-engagement multiplier, and tenure-based experience curve, with a revenue sanity cap on the defensible high end. Produces a salary RANGE — defensible against Watson v. Commissioner (8th Cir. 2012) and Glass Blocks v. Commissioner (T.C. Memo 2013-180) recharacterization risk.

    Why this matters

    The IRS attacks S-corp owner under-compensation by recharacterising distributions as wages — assessing back FICA, plus failure-to-deposit penalties (up to 15%) and accuracy penalties (20%). The 8th Circuit's Watson decision recharacterised $24,000 of declared salary into $91,044, with FICA assessed against the difference. The risk is concrete and audit-attractive.

    Approach 1: Market (BLS OEWS anchor)

    Pull the median OEWS wage for the owner's SOC (Standard Occupational Classification) code in their MSA. Then apply four adjustments: 1. Regional cost-of-labor index (BLS provides MSA-level multipliers) 2. Hours-of-engagement factor (median OEWS assumes 2,080 hours — pro-rate part-time) 3. Experience curve (10th/50th/90th percentile band; senior owners at p75–p90) 4. Revenue sanity cap (high-end percentile only defensible if business revenue supports it) This produces a defensible RANGE, not a single number. The TaxKiln BLS Reasonable-Comp Framework calculator implements this with 2026 OEWS data.

    Approach 2: Cost (replacement-cost build-up)

    What would the S-corp pay an arms-length employee to perform each function the owner performs? Build a job-by-job replacement schedule: 0.5 FTE bookkeeper at $52k, 0.3 FTE marketing manager at $85k, 0.6 FTE technical lead at $130k, and so on. Sum the fractions × market rates. This approach is strongest for owners wearing multiple hats in small businesses.

    Approach 3: Income (independent-investor test)

    Used historically in executive comp cases (Exacto Spring v. Commissioner, 7th Cir. 1999). The question: would an independent investor in the company consider the owner's compensation reasonable given the return they receive after that comp is paid? If post-comp ROI is strong, the comp is defensible — even if high in absolute terms. Weakest of the three for typical S-corp owners; useful as a sanity check for high-comp positions.

    Documentation that survives audit

    Maintain a contemporaneous reasonable-compensation file: • Job description and time allocation • BLS OEWS data print with year, MSA, and SOC code • Adjustment workings (region, hours, experience, revenue) • Annual reasonable-comp memo signed by the owner and dated before year-end The difference between an unfavourable audit and a sustained position is usually documentation contemporaneous with the comp decision — not retrofitted after a notice arrives.

    Worked example: Marcus Lee, S-corp orthodontist (Phoenix, AZ)

    Marcus's S-corp grosses $920,000 with $310,000 net profit before owner comp. He wants to set defensible 2026 comp.

    Market approach: SOC 29-1023 (Orthodontists), Phoenix-Mesa MSA, OEWS May 2026 median: ~$245,000 Regional COL index: 0.98 → 240,100 Hours: full-time 2,080 → 1.0 multiplier Experience: 14 years (p75 band) → 285,000 Revenue sanity: $920k gross supports high end Market band: $245k–$320k; midpoint $282,500 Cost approach: Replacement orthodontist 0.85 FTE × $240k = $204,000 Practice manager 0.10 FTE × $95k = 9,500 Marketing 0.05 FTE × $80k = 4,000 Total: ~$217,500 Independent-investor test: After $280k comp, distribution = $30k ROI for an arms-length investor: thin — supports high-end comp Reasonable-comp decision: $280,000 W-2. Distribution: $30,000. FICA cost: 2.9% × 280k (over SS base) + 12.4% × 184,500 + 0.9% Add'l Medicare over $200k = ~$31,000.
