Horst: Assigning Interest Coupons Did Not Shift the Taxable Income

By Aneeta Mishra and Timothy Chan

Published September 13, 2026

Helvering v. Horst applies the assignment-of-income doctrine to the transfer of a right to receive interest.

The owner kept the bonds but transferred coupons

Before maturity, the taxpayer gave negotiable interest coupons to his son, who collected them in the same year.

Control over the income source mattered

The taxpayer retained the bonds and used his ownership to direct who would receive the current yield.

Enjoyment can amount to realization

Realization occurred when the owner procured payment to his chosen recipient, even though he did not personally receive the cash.

The interest was taxed to the owner

The Court reversed the contrary judgment and applied the assignment-of-income principle to the coupon payments.

Key takeaways

• Identify who owns and controls the income-producing property.
• Distinguish transferring property from assigning its current income.
• Track when the recipient collects the assigned payment.
• Apply contemporary gift and income-reporting rules together.
