National Carbide Corp. v. Commissioner of Internal Revenue

Opinion summary

Etalia.ai summary of the majority opinion

The case addressed whether six subsidiary corporations, wholly owned by National Carbide Corporation and operating under its control, should be treated as separate taxable entities or merely agents of the parent company for federal tax purposes. The subsidiaries were engaged in manufacturing operations using facilities leased from National Carbide and sold their products exclusively to it at prices set by the parent corporation. The Supreme Court held that despite the close relationship between National Carbide and its subsidiaries, they maintained distinct corporate identities with their own books, officers, employees, and bank accounts. Therefore, they should be recognized as separate taxable entities rather than mere instrumentalities or agents of the parent company. This decision reinforced the principle that formal corporate structures are respected for tax purposes unless there is clear evidence showing a lack of independence.
