P.G. Lake: Selling a Carved-Out Right to Future Income Produced Ordinary Income

By Aneeta Mishra and Timothy Chan

Published September 15, 2026

Commissioner v. P.G. Lake, Inc. consolidated transactions in which taxpayers carved limited oil, gas, or sulphur payment rights from larger mineral interests and received present consideration for assigning those rights.

The assigned rights represented future production income

The transferees were entitled to specified payments from production. The taxpayers retained the larger income-producing interests after carving out the limited rights.

Present cash substituted for future ordinary income

The Court focused on the substance of what was sold. The consideration compensated the taxpayers for the right to receive income that otherwise would have been taxable as ordinary income, not for growth in the value of an underlying investment.

Capital-gain form did not change income character

A formally transferable property right can still represent an anticipatory assignment of income. The Court treated the proceeds as ordinary income, subject to the depletion rules applicable to the mineral income.

The like-kind argument also failed

In one consolidated case, exchanging carved-out oil-payment rights for real estate did not qualify under the then-governing like-kind provision. Current transactions require analysis under today’s substantially revised section 1031.

Key takeaways

• Identify whether the transferred right is principally a right to future income.
• Determine what income-producing property the taxpayer retained.
• Do not infer capital treatment from assignability alone.
• Apply current depletion and like-kind-exchange statutes separately.
