Proposed Changes to U.S. Portfolio Interest Exception
September 24, 2021

Proposed changes to 10% shareholder definition

The U.S. portfolio interest exception is a tax incentive to make investments in the United States more attractive to non-U.S. investors. The portfolio interest exemption provides relief from the default withholding tax rate of 30% on U.S.-sourced interest income in certain circumstances.


One of the requirements for a valid portfolio interest exception is that the beneficial owner of the interest income is not a 10% shareholder of the borrower. Under current law, a 10% shareholder includes any person who owns 10% or more of the total combined voting power of all classes of stock of a corporate borrower.


In connection with Build Back Better Act tax proposals, there is a proposed change to the 10% shareholder definition. According to the proposal, a 10% shareholder includes any person who owns 10% or more of the total combined voting power of all classes of stock or 10% or more of the total value of the stock of a corporate borrower. The proposal would be effective after the date of enactment of the law.


The proposal may have a significant impact on investment funds with U.S. assets. In particular, the proposal is most likely to impact investors who do not qualify for U.S. income tax treaty benefits.
