Overview

Building on our strategies for above-the-line health premiums (Episode 8) and actual vehicle acceleration (Episode 7), Episode 9 steps into advanced entity planning: Corporate Fringe Benefits & C-Corp Arbitrage.

Key Takeaways & Statutory Framework

• The S-Corp Limitation (IRC § 1372): S-Corp owners owning 2% of shares are treated as partners for fringe benefit purposes.
• C-Corp Fringe Suite: C-Corporations pay a flat 21% federal rate and can provide 100% tax-free statutory employee perks:
  • IRC § 79: Up to $50,000 in group-term life insurance premiums paid tax-free.
  • IRC § 129: Up to $5,000–$7,500 year in tax-free dependent care assistance or corporate Dependent Care FSAs.
  • IRC § 127: Up to $5,250 year in tax-free tuition or student loan repayments.
  • IRC § 132: Qualified transit, executive parking up to 325 month, and working condition tools.
• The Disability Insurance Lookback Hack (IRC §§ 104 & 105):
  • The Trap: If your business deducts disability premiums in the policy year, proceeds received during an injury are 100% taxable.
  • The Proactive Fix: Pay disability premiums out of personal, post-tax funds during the active coverage year (keeping claims 100% tax-free).

Evaluating a physician incurring $25,000 annually in family out-of-pocket medical copays,

1. Scenario A: Single S-Corp (No Strategy)

Under IRC § 1372, fringe benefits cannot be excluded. You must fund $25,000 in personal after-tax dollars:

Gross Income Required} = $25,000/1 - 0.37 = $39,682.54 Tax Paid on Dollars Spent = $39,682.54 X 37% = $14,682.54

2. Scenario B: Dual-Entity C-Corp Arbitrage (Physician Tax Solutions)

Your S-Corp pays a $25,000 arm's-length management fee to your sister C-Corp MSO, which adopts formal written fringe benefit plans:

1. S-Corp Deducts Management Fee (37%): $25,000 X 37% = $9,250 tax saved
2. C-Corp Fringe Offset: $25,000 revenue} - $25,000fringe expenses} =$0 corporate tax
3. Tax-Free Receipt: You receive $25,000 in fringe benefits 100% tax-free.

Net Annual Cash Difference:

Immediate Cash Saved = $9,250 + $14,682.54 = $23,932.54 Kept in Your Family Pocket

Audit-Proof Compliance Checklist

1. Arm's-Length Management Agreement: Execute a formal contract detailing bona fide administrative, billing, or IT services at fair market value.
2. Entity Substance: Maintain separate bank accounts, EINs, corporate minutes, and general ledgers for the C-Corp MSO.
3. Written Plan Documents: Adopt formal written plans for Section 105, Section 79, and Section 129 before processing reimbursements.
4. Non-Discrimination Testing: Ensure benefits satisfy statutory rules across all non-owner employees.
