Kernrechtsfrage
Whether Y.'s share of the real estate sale proceeds is taxable as income from self-employment or exempt private capital gain under direct federal tax.
Extrahierter Entscheid
The gain was attributable to self-employment income: the building company conducted a business activity, the property remained business assets, and the later sale continued that activity.
Extrahierte Begründung
The court relied on the original business purpose, the corporate structure, the absence of any recognized transfer to private assets, the planned resale in the founding purpose, and the accounting treatment, concluding that the later long holding period did not transform the asset into private property.
