Summary

Makes broad changes to U.S. international tax law that mostly take effect for taxable years beginning after December 31, 2025. The bill revises how U.S. shareholders and controlled foreign corporations (CFCs) treat foreign-source dividends, modifies rules for Global Intangible Low‑Taxed Income (GILTI) and the foreign tax credit, creates a new rule for transfers of intangible property from CFCs to U.S. shareholders, adjusts base erosion and anti‑avoidance provisions, and changes several look‑through, attribution, and carryover rules to limit tax avoidance and reallocate deductions. The package alters many Internal Revenue Code cross‑references and definitions, directs Treasury to issue implementing regulations for certain changes, and adds transition and anti‑abuse rules. The changes affect multinational companies, U.S. domestic corporations with foreign affiliates, foreign corporations treated as CFCs, tax compliance and reporting, and IRS/Treasury administration of international tax provisions.

Key Points

• Overhauls many international tax rules affecting CFCs, U.S. shareholders, GILTI, Subpart F, foreign tax credits, BEAT, and constructive ownership.
• Adds a sourcing rule so certain CFC‑received dividends from 10%-owned foreign corporations are treated as if the U.S. shareholder received the foreign‑source portion.
• Creates a new special rule for transfers of intangible property from CFCs to U.S. shareholders that limits valuation/basis outcomes and is intended to curb tax avoidance.
• Removes the GILTI foreign tax credit haircut and revises how foreign taxes are characterized and allocated against GILTI and other baskets.
• Changes BEAT and deduction‑apportionment mechanics, narrows categories of foreign base company income, and provides a net CFC tested loss carryover.
• Restores limits on downward attribution and adds new rules for foreign‑controlled U.S. shareholders and foreign‑controlled CFCs to tighten attribution.
• Applies mostly to taxable years beginning after Dec 31, 2025, and requires extensive Treasury/IRS rulemaking and guidance.
• Will increase compliance, valuation, and reporting burdens for multinational firms and their tax advisers.
• Contains multiple anti‑abuse and transition rules but relies on future regulations to fill in technical details.
