National Carbide Corp. v. Commissioner
The Court ruled that three subsidiary companies owned by Air Reduction Corporation had to pay income tax on the profits they earned, even though their contracts required them to turn nearly all of that money over to their parent company.
The decision confirmed that a corporation carrying on real business activity cannot escape taxation by labeling itself an 'agent' of its owner, cutting off a tax-avoidance strategy built around a much older, narrower precedent.
“Ownership of a corporation and the control incident thereto can have no different tax consequences when clothed in the garb of agency than when worn as a removable corporate veil.”
Explaining why calling a subsidiary an 'agent' cannot change its tax obligations.
How it got here: The Tax Court ruled for the subsidiaries; the Second Circuit reversed; the Supreme Court agreed to hear the case due to a conflict among courts.
The Case in Depth
What happened
Air Reduction Corporation (Aireo) ran its business through four wholly owned subsidiaries, each handling manufacturing and sales in a different product line. Contracts required the subsidiaries to turn over all profits above a nominal six percent return to Aireo, which supplied their capital and management. The subsidiaries reported only their small retained amounts as taxable income for 1938, while Aireo reported the rest as its own.
The question before the Court
Could three wholly owned subsidiaries avoid paying corporate income tax on their profits by claiming they were merely tax-collecting agents for their parent company?
Why it matters
Businesses that operate through wholly owned subsidiaries cannot dodge corporate taxes simply by writing contracts that call the subsidiary an 'agent' required to hand over its profits. Each active operating subsidiary must pay tax on the income it actually earns, closing off a structuring technique some corporate groups might otherwise have used to shift tax liability.
What changes now
This is a final merits decision resolving the tax dispute for the 1938 tax year; the judgment of the Court of Appeals for the Second Circuit, which had already ruled against the subsidiaries, is affirmed. The subsidiaries remain liable for the income and excess-profits tax deficiencies the Commissioner assessed. The ruling also settled a disagreement among lower courts over whether the older Southern Pacific precedent still controlled such arrangements, confirming it does not for ordinary operating subsidiaries.
What this does not decide
The Court did not decide that a corporation can never act as a true tax agent for its owner — it left open that a genuine agent handling its principal's property, acting in the principal's name and using the principal's own assets and employees, could still avoid tax on income belonging to the principal.

How the Court got there
The legal reasoning, step by step
- The Court examined whether the subsidiaries' relationship with Aireo fit the 'usual incidents of an agency relationship,' the standard set in an earlier case (Moline Properties) for when a corporation's income can instead be taxed to its owner.
- The Court concluded that Southern Pacific Co. v. Lowe, the older case the subsidiaries relied on, never actually established a rule about agency; it had instead treated a parent and subsidiary as practically the same entity solely because of complete ownership and control, for a narrow purpose tied to when the 1913 income tax law took effect.
- Because later decisions had rejected the idea that complete ownership and control alone can excuse a business-operating corporation from taxation, the Court held that ownership and control dressed up as 'agency' could not change the tax result any more than simply ignoring the corporate form outright.
- The Court identified the real markers of a true agency relationship — acting in the principal's name, binding the principal, and earning income through the principal's own assets and employees rather than the subsidiary's own labor and capital — and found none of them present here.
- Applying those markers, the Court found the subsidiaries used their own employees, their own assets, and their own labor to generate the income, so they — not Aireo — had earned it, regardless of the contractual promise to pass profits upward.
