In brief
On December 12, 2025, US Treasury and the IRS issued long-anticipated final regulations under section 892 ("Final Regulations") and new proposed regulations under section 892 ("Proposed Regulations"). The Final Regulations clarify (i) the framework for determining when non-US government investors are engaged in commercial activity, and (ii) when entities are treated as controlled commercial entities (CCEs). The Final Regulations finalize proposed regulations issued in 2011 and 2022, with important modifications affecting non-US governments, sovereign wealth funds, central banks, certain foreign pension funds, and other similar investors ("Section 892 Investors") in private equity, private credit, infrastructure, and real estate investment structures. The Proposed Regulations provide guidance on determining (i) when the acquisition of debt rises to the level of commercial activity, and (ii) when an investor has effective control of an entity.
Key takeaways
- Broader Commercial Activity Definition. The concept of “commercial activity” remains broader than the concept of “US trade or business” and is now explicitly independent of section 864(b).
- Expanded Investment & Trading Safe Harbors. Safe harbors now clearly cover standard market derivatives, offering greater certainty for common trading strategies. However, bespoke or asset-linked instruments are excluded.
- Heightened Partnership Attribution Risk. Partnership attribution remains a central risk. Simply labeling income as “fees” or “passive” will not prevent commercial activity income (CAI) attribution.
- 2011 LP Exception Conceptually Retained but Tightened. The “limited partner exception” ("LP Exception") from the 2011 proposed regulations has been conceptually retained and formalized into a “qualified partnership interest exception” ("QPI Exception"). However, the QPI Exception does not apply to “controlled” investments where the Section 892 Investor holds a 50% or greater interest (by vote or value) in, or has effective control over, the partnership,
- Narrowed USRPHC Per Se Rule. The USRPHC per se CCE rule is narrowed to apply only to domestic corporations, which is a favorable change for cross-border real estate investment structures.
- Formalized Inadvertent Commercial Activity Exception. While helpful, this exception requires robust compliance, including documentation, monitoring, and timely corrective actions.
The Final Regulations will take effect when published in the Federal Register and can, at the taxpayer’s election, be applied retroactively for prior years for which the assessment limitation period has not yet closed. The Proposed Regulations would take effect when finalized and published in the Federal Register. Once finalized, those regulations, at the taxpayer’s election, may be applied retroactively for prior years for which the assessment limitation period has not yet closed.
