In the case of Kirby Petroleum Co. v. Commissioner of Internal Revenue, 1945, the U.S Supreme Court was tasked with determining whether or not payments received by Kirby Petroleum Company from its oil and gas leases could be considered capital gains or ordinary income for tax purposes. The company had leased out land to other companies who then extracted and sold oil and gas; in return, Kirby received a percentage of these sales as payment (royalties). The IRS argued that these royalties were regular income subject to higher tax rates while Kirby contended they should be treated as capital gains which are taxed at lower rates. The court sided with the IRS ruling that such payments constituted part of the gross income derived from their business operations rather than proceeds from sale of assets hence taxable as ordinary income.

In the dissenting opinion for Kirby Petroleum Co. v. Commissioner of Internal Revenue, Justice Jackson argued that the majority's decision to allow a tax deduction for oil and gas royalties paid in advance was inconsistent with previous rulings on similar cases. He contended that these payments should be considered capital investments rather than ordinary business expenses because they were made to secure future income streams from oil and gas production. As such, he believed they should not be immediately deductible but instead amortized over the life of the related leases or contracts. This interpretation would align more closely with general principles of taxation which aim to match deductions with corresponding income recognition periods.
