Decision: Moline Properties, Inc. v. Comm’r, 319 U.S. 436 (1943).

Moline Properties, Inc. v. Commissioner concerned gain from real-estate sales by a corporation whose sole shareholder sought to report the transactions as his own.

The corporation held and sold property

The entity was created in connection with mortgaged real estate, took title, dealt with the property, and later made the sales producing the disputed gains.

Ownership alone did not erase the entity

Complete stock ownership and control did not make the corporation’s income automatically the shareholder’s income.

Business purpose or activity sustains separateness

So long as the corporation served a business purpose or actually conducted business, its separate tax identity ordinarily controlled.

The gains belonged to the corporation

The Court affirmed the corporate deficiencies and rejected the claim that the corporation acted merely as the shareholder’s agent on this record.

Key takeaways

• Respect the entity actually used for the transaction.
• Document formation purpose and continuing activity.
• Do not equate sole ownership with tax agency.
• Analyze genuine agency, sham, and later statutory rules separately.
