In exchange, Alex receives Innovate Corp. stock with a fair market value of $150,000 and $30,000 in cash. What is the amount of gain that Alex must recognize on this §351 exchange?

Worked Practitioner Scenario

Comprehensive Worked Example: §351 in Action

Scenario: Maria forms a new C corporation, M-Corp. She transfers the following assets in exchange for 100% of M-Corp's stock and $10,000 cash.

  1. | Asset | Maria's Basis | Fair Market Value | Liability Assumed by M-Corp | | :--- | :--- | :--- | :--- | | Land | $100,000 | $250,000 | $120,000 (Mortgage) | | Equipment | $60,000 | $50,000 | $0 | | Total | $160,000 | $300,000 | $120,000 |
  2. Let's calculate the tax consequences step-by-step.
  3. Step 1: Calculate Realized Gain Total Consideration Received: $300,000 (FMV of assets transferred) Realized Gain: $300,000 (Consideration) - $160,000 (Total Basis) = $140,000
  4. Step 2: Calculate Recognized Gain First, check for gain from liabilities in excess of basis (§357(c)). Total liabilities ($120,000) are NOT greater than total basis ($160,000). No gain from this rule. Identify boot received. Maria received $10,000 cash. Under §357(a), the liability assumption is not boot for gain recognition purposes here. Recognized Gain is the lesser of Realized Gain ($140,000) or Boot Received ($10,000). Recognized Gain = $10,000
If you picked a recognized gain of $130,000, you likely made the common mistake of treating the assumed liability as boot for gain recognition. Remember, under the general rule of §357(a), liabilities assumed are not boot for calculating gain. They only reduce the shareholder's stock basis.
