Multinational tax teams spent late 2024 mapping entity structures against a new set of rules that could force U.S. income inclusions on foreign-deductible payments. The IRS disregarded payment loss rules proposal arrived in August 2024 as part of broader dual consolidated loss updates, was finalized in early 2025, and then faced a formal withdrawal announcement later that year. This guide explains what the rules targeted, how they intersected with section 1503(d), why stakeholders pushed back, and the concrete steps tax directors should take now while the landscape remains in flux.
Background on Dual Consolidated Loss Rules and Section 1503(d)
Section 1503(d) limits the ability of dual resident corporations and separate units (foreign branches and certain hybrid entities) to use the same economic loss to offset both U.S. and foreign taxable income. The classic concern is a double deduction: a loss reduces the U.S. consolidated group’s taxable income while simultaneously offsetting income of a foreign affiliate under foreign law.
Existing dual consolidated loss regulations require domestic use elections, tracking periods, and recapture if a foreign use occurs. The “all-or-nothing” principle has long drawn criticism: any foreign use of even a small portion of a dual consolidated loss can trigger full recapture. These rules focus on items that are regarded for U.S. tax purposes. They left open a structural gap involving disregarded entities.
What the IRS Disregarded Payment Loss Rules Proposal Targeted
Treasury and the IRS issued proposed regulations (REG-105128-23) on August 6-7, 2024. The package addressed several dual consolidated loss issues, including interaction with Pillar Two taxes, and introduced an entirely new regime for disregarded payment losses.
A disregarded payment loss arises when a disregarded entity (or certain foreign branches or dual resident corporations) makes payments that are deductible under foreign tax law but disregarded for U.S. tax purposes. The payments in scope were primarily interest, royalties, and structured payments. Because the payments vanish for U.S. purposes, no corresponding income inclusion occurs in the United States, creating a deduction/non-inclusion outcome.
The proposed solution operated through the entity classification rules under section 7701. A domestic corporation that owned a “specified eligible entity” (generally a foreign tax resident or an entity owned by a domestic corporation with a foreign branch) would consent to the disregarded payment loss rules as a condition of the entity remaining or becoming disregarded. Deemed consent applied in many cases after a delayed effective date.
Once subject to the rules, the domestic owner monitored the foreign-law net loss attributable to the covered disregarded payments. A “triggering event” within a certification period (the year of the loss plus 60 months) required an income inclusion. Triggering events included foreign use of the loss (for example, under a group relief or consolidation regime) or failure to file required certifications.
Interaction with Dual Consolidated Loss Regulations
The disregarded payment loss rules were designed to operate independently of, yet in parallel with, the dual consolidated loss framework. Dual consolidated losses apply to regarded items. Disregarded payment losses targeted the disregarded items that escaped that net. An anti-avoidance rule applied to both regimes, and ordering rules coordinated the two when both could potentially apply. The proposal also addressed foreign branch combination rules and certain stock-ownership items in dual consolidated loss calculations.
Finalization in Early 2025 and Key Modifications
On January 10-14, 2025, Treasury and the IRS released final regulations (T.D. 10026) that largely retained the structure of the proposed disregarded payment loss rules while making targeted changes.
Applicability was deferred: the disregarded payment loss rules generally applied to taxable years of disregarded payment entity owners beginning on or after January 1, 2026. The final rules introduced a de minimis exception, excluded certain pre-proposal royalty arrangements, refined the definition of a disregarded payment entity, and clarified treatment of foreign branches held through partnerships. They also provided for a suspended deduction mechanism in limited cases and clarified that disregarded payment loss inclusions generally did not feed into dual consolidated loss calculations.
The final package retained the anti-avoidance rule and certain ordering provisions. Taxpayers and advisors immediately faced significant compliance questions: identifying every covered payment stream, building certification processes, modeling potential inclusions, and evaluating whether to restructure ownership or payment arrangements before the 2026 effective date.
Industry Response and Calls for Withdrawal
Comments on the 2024 proposal were extensive and largely critical. The U.S. Chamber of Commerce argued that the disregarded payment loss rules lacked statutory authority under sections 1503(d) and 7701 and represented an unauthorized expansion beyond congressional intent. The Silicon Valley Tax Directors Group highlighted policy inconsistencies, the creation of taxable income without clear statutory basis, and the risk of over-inclusion of ordinary-course transactions. Other groups, including the National Foreign Trade Council, later reinforced concerns about complexity, cost, and the departure from longstanding principles of the Code.
Stakeholders emphasized that the dual consolidated loss statute was written to police double deductions of regarded losses, not to invent income inclusions for disregarded payments. Many letters also questioned the practical administrability of tracking foreign-law losses, foreign use, and multi-year certification periods across complex multinational structures.
Notice 2025-44 and the Planned Withdrawal
On August 20, 2025, Treasury and the IRS issued Notice 2025-44. The notice announced the intention to propose regulations that would remove the disregarded payment loss rules under Treas. Reg. §1.1503(d)-1(d) and related modifications to the dual consolidated loss rules (including certain deemed ordering provisions). An exception would be added to the anti-avoidance rule so that it would not reach structures previously targeted by the disregarded payment loss regime.
The forthcoming proposed regulations were expected to apply to taxable years beginning on or after January 1, 2026 (the same date the final disregarded payment loss rules would have taken effect). Taxpayers may rely on the notice until those proposed regulations are published. In practical terms, the rules are not expected to apply.
The notice also extended transitional relief for the interaction of dual consolidated loss rules with the GloBE Model Rules (Pillar Two). Dual consolidated loss rules would generally be applied without regard to qualified domestic minimum top-up taxes and top-up taxes for losses incurred in taxable years beginning before January 1, 2028. This extension provides additional time for further OECD developments and domestic consideration of comments.
Finally, the notice requested comments (due October 21, 2025) on two longstanding dual consolidated loss issues: whether the all-or-nothing principle should be revised, and how disregarded items should be treated for dual consolidated loss purposes. Industry groups have continued to urge elimination or substantial softening of the all-or-nothing rule.
Practical Implications for Multinational Structures
Even with withdrawal planned, the episode carries lasting lessons. Many groups accelerated reviews of disregarded entities that make cross-border interest or royalty payments deductible under foreign law. Some began modeling alternative structures (regarded entities, partnership classifications, or revised intercompany agreements). Others paused planned restructurings once the notice appeared.
Key risk areas that remain relevant under existing dual consolidated loss rules include:
- Foreign branches and hybrid entities that generate dual consolidated losses.
- Group relief or consolidation regimes that could create foreign use.
- Interaction of dual consolidated losses with Pillar Two top-up taxes once transitional relief expires.
- Documentation and certification processes that many companies strengthened in anticipation of the disregarded payment loss regime.
Tax executives should also monitor whether future guidance under section 1503(d) incorporates any residual concepts from the disregarded payment loss project, particularly around disregarded items or ordering.
Strategic Steps to Prepare for Compliance or Withdrawal
- Inventory all disregarded entities, dual resident corporations, and foreign branches owned by domestic corporations. Flag those that generate foreign-law interest, royalty, or structured payment deductions.
- Map intercompany payment flows that are disregarded for U.S. purposes but deducted abroad. Quantify potential foreign-law losses and identify any existing group relief or fiscal unity arrangements.
- Review entity classification elections and ownership chains. Confirm whether any elections were conditioned on, or made in contemplation of, the disregarded payment loss consent regime.
- Assess documentation readiness. Even without the disregarded payment loss rules, dual consolidated loss compliance requires robust tracking of losses, domestic use elections, and foreign use events.
- Model the impact of potential all-or-nothing reforms. Scenario-plan both retention of the current rule and possible item-by-item or proportional approaches.
- Coordinate with Pillar Two modeling. The extended transition relief through tax years beginning before 2028 creates a window to refine GloBE and dual consolidated loss interactions.
- Preserve optionality. Avoid irreversible restructurings solely to accommodate rules that are now expected to be withdrawn, but maintain the ability to adjust if future guidance reintroduces similar concepts.
- Engage with trade associations and submit comments where appropriate. The request for input on the all-or-nothing principle remains open for consideration in future rulemaking.
Common Pitfalls to Avoid
Do not assume that withdrawal eliminates all dual consolidated loss exposure. Regarded losses continue to be subject to the existing regime. Do not overlook foreign branches held through partnerships; final regulations clarified that such branches can still present dual consolidated loss issues. Avoid treating certification or tracking systems built for the disregarded payment loss rules as disposable; many of those processes improve dual consolidated loss governance. Finally, do not wait for final withdrawal regulations before updating internal controls. Reliance on Notice 2025-44 is available now, but internal policies should reflect the current expected state of the law.
Looking Ahead: Pillar Two Alignment and Future Guidance
The disregarded payment loss episode sits within a broader effort to align U.S. anti-hybrid and dual-use rules with international standards, including Pillar Two. While the specific disregarded payment loss mechanism is being removed, the underlying policy concern (preventing certain deduction/non-inclusion outcomes) has not disappeared. Future guidance could address similar issues through other authorities, legislative change, or refined dual consolidated loss rules. Tax teams should treat the current pause as an opportunity to strengthen foundational dual consolidated loss compliance rather than a permanent resolution of hybridity concerns.
Conclusion
The IRS disregarded payment loss rules proposal, its 2025 finalization, and the subsequent Notice 2025-44 withdrawal announcement illustrate both the reach of regulatory anti-abuse efforts and the practical limits of authority and administrability. Multinational tax directors now operate in a clearer environment for disregarded payments, yet dual consolidated loss rules under section 1503(d), the all-or-nothing principle, and Pillar Two interactions remain active areas of focus. Inventory structures, reinforce tracking systems, and stay engaged with ongoing guidance. Consult experienced international tax counsel to evaluate your specific entity and payment arrangements against the current dual consolidated loss framework and the expected removal of the disregarded payment loss rules.
Frequently Asked Questions
What is a disregarded payment loss under the IRS proposal?
A disregarded payment loss is a foreign-law net loss of a disregarded entity (or certain other entities) attributable to interest, royalties, or structured payments that are deductible abroad but disregarded for U.S. tax purposes.
When were the disregarded payment loss rules supposed to apply?
The final regulations made them applicable to taxable years of owners beginning on or after January 1, 2026. Notice 2025-44 indicates forthcoming proposed regulations will remove them for the same periods.
Do the dual consolidated loss rules still apply after the planned DPL withdrawal?
Yes. Dual consolidated loss rules under section 1503(d) continue to govern regarded losses of dual resident corporations and separate units.
What is the current status of the all-or-nothing principle?
It remains in force. Notice 2025-44 requested comments on possible revisions, and many commenters have urged its elimination or softening.
How does Pillar Two interact with dual consolidated losses?
Transitional relief generally prevents qualified domestic minimum top-up taxes and top-up taxes from creating foreign use for dual consolidated losses incurred in taxable years beginning before January 1, 2028.
Should companies unwind structures adopted in anticipation of the DPL rules?
Not automatically. Evaluate each structure on its merits under existing dual consolidated loss rules and commercial considerations. Many adjustments may still be beneficial or neutral.
Where can taxpayers find the official guidance?
See REG-105128-23 (2024 proposed), T.D. 10026 (2025 final), and Notice 2025-44, all available on IRS.gov and the Federal Register.
