On December 15, 2025, the US Internal Revenue Service (IRS) issued both proposed regulations and final regulations under Section 892 relating to the taxation of income of foreign governments from investments in the United States (the Proposed Regulations and Final Regulations, respectively). On June 1, the IRS issued further proposed regulations modifying the applicability dates for when these proposed regulations will take effect.
The Proposed Regulations included guidance on:
Those rules were originally proposed to apply to taxable years beginning on or after the date of publication of the Treasury decision adopting the Proposed Regulations as final regulations (the publication date).
On June 1, 2026, the IRS issued further proposed regulations modifying the applicability dates for when the Proposed Regulations, once finalized, will take effect. Specifically, the IRS has withdrawn the prior applicability dates and proposed new applicability dates, clarifying that the Proposed Regulations will not apply retroactively to existing foreign government holdings of debt and of interests in entities.
The IRS has also included additional transitional relief for the applicability of the Proposed Regulations, providing foreign governments with a transition period of at least 90 days after the publication date or until the start of the first taxable year after the publication date (whichever is later), before the new rules can apply (the transition date).
As a result of these new applicability dates:
These revised applicability dates are a welcome clarification to sovereign investors who may have previously been concerned that they would need to restructure their existing investments once the Proposed Regulations were finalized.
The IRS has also stated that the Treasury Department and the IRS are evaluating how to revise the Proposed Regulations to address the public comments they’ve received to date, including with respect to the debt acquisition and effective control rules, although no specific timeline was provided.
