The One Big Beautiful Bill Act (OBBBA), signed into law in July 2025, introduces critical updates to U.S. international taxation. These reforms aim to simplify compliance and alter several key provisions affecting multinational businesses with U.S. ties. Here’s a concise overview of the most significant changes.
1. Key Changes to GILTI and FDII
OBBBA revises two central regimes affecting outbound U.S. investment: GILTI (now NCTI) and FDII (now FDDEI).
Terminology Updates:
- “Global Intangible Low-Taxed Income (GILTI)” has been renamed to Net CFC Tested Income (NCTI).
- “Foreign-Derived Intangible Income (FDII)” is now termed Foreign-Derived Deduction Eligible Income (FDDEI).
Section 250 Deduction Rates Reduced:
- Starting in 2026, the FDDEI deduction drops to 33.34%, and the NCTI deduction reduces to 40%.
- Effective tax liabilities are expected to rise, with less income shielded from U.S. taxation. For example, a multinational previously benefiting from a 50% GILTI deduction will now face higher U.S. taxes on comparable income.
- Companies should model the effect of lower deductions on both cash tax outflows and financial statement provisions tied to deferred tax liabilities.
Exemption Changes:
- Qualified Business Asset Investment (QBAI) is now excluded from NCTI and FDDEI calculations.
Effective Tax Rates (ETRs):
- After applying foreign tax credits, both NCTI and FDDEI have an ETR of 14%, effective 2026.
2. Subpart F and CFC Adjustments
Changes to Subpart F and Controlled Foreign Corporation (CFC) provisions could affect U.S. shareholders’ compliance requirements and cross-border structures:
Stock Attribution:
- The restoration of Section 958(b)(4) prevents certain U.S. subsidiaries of foreign parents from achieving unintended Controlled Foreign Corporation (CFC) status.
Pro Rata Allocation:
- Subpart F and NCTI are now allocated based on a shareholder’s pro rata share of income during the tax year, regardless of year-end stock ownership.
Look-Through Rule Made Permanent:
- Certain related party payments (like dividends and interest) continue to be excluded from Subpart F income under specific conditions.
CFC Tax Year Alignment Eliminated:
- The ability for CFCs to elect tax years different from their majority U.S. shareholder is removed for tax years starting after November 30, 2025, potentially requiring short-year filings.
3. Base Erosion and Anti-Abuse Tax (BEAT) Fixed Rates and Forward Planning
- Permanent Rate Set: The BEAT rate has been set at 10.5%, effective for tax years after December 31, 2025.
- While the rate stabilization may reduce future tax increases, BEAT remains a critical factor for U.S. inbound and outbound groups with substantial related-party payments.
- Businesses routing payments to foreign affiliates should review their payment structures to mitigate BEAT exposure.
How Does This Impact Your Business?
For instance, if your company operates a Controlled Foreign Corporation (CFC) in a low-tax jurisdiction and relies on the Qualified Business Asset Investment (QBAI) exemption to reduce GILTI, the exclusion of QBAI from the new Net CFC Tested Income (NCTI) calculation could increase your effective tax rate. Additionally, if your business has related party payments between CFCs, the permanent look-through rule may provide relief by excluding certain payments from Subpart F income.
Key Questions to Consider:
- Do you have foreign subsidiaries that may now qualify as CFCs under the restored Section 958(b)(4)?
- Are you leveraging foreign tax credits to offset GILTI or FDDEI?
- Will the removal of the CFC tax year alignment require adjustments to your filing processes?
These changes signal a pivotal shift in U.S. international tax policy, requiring businesses to adjust strategies and ensure compliance.
