Allocation and Apportionment of Deductions to Foreign Source Section 951A Category Income and Deduction Eligible Income
Key claim: The IRS is proposing how companies must assign expenses to certain foreign income, which would change their foreign tax credits and the special deduction for income from selling goods and services abroad.
Abstract
(Proposed Rule · Treasury Department, Internal Revenue Service) This document contains proposed regulations related to the allocation and apportionment of deductions to foreign source section 951A category income for foreign tax credit limitation purposes and for purposes of calculating deduction eligible income. The proposed regulations would affect taxpayers that operate in foreign countries through foreign corporations and domestic corporations that claim the deduction for foreign-derived deduction eligible income.
Why this matters
Deduction allocation and apportionment rules are the mechanical hinge that determines how much foreign tax credit a U.S. multinational can actually use and how large its FDII deduction ends up being. Even technical proposed changes shift after-tax outcomes on cross-border earnings and can favor or disadvantage exporters versus companies with significant foreign operations. Tracking this rulemaking keeps the vault current on the plumbing behind GILTI/FDII, which sits at the core of U.S. international corporate tax.
