The Profit Shifting Debate

Country-by-Country Reporting was designed to help tax authorities detect profit shifting by requiring multinationals to disclose detailed financial information across jurisdictions. But new research reveals an unexpected consequence: firms responded not just by changing accounting practices, but by reallocating real economic activity—moving tangible assets and employees to low-tax jurisdictions. This analysis examines how transparency regulations can reshape where companies invest and what that means for tax policy.

Has U.S. outbound income shifting—where corporations transfer income from the U.S. to foreign tax havens—decreased following the Tax Cuts and Jobs Act of 2017? Using data from both the Bureau of Economic Analysis and firm-level sources, this analysis tracks the share of U.S. corporate profits recognized in tax haven jurisdictions over nearly three decades to assess recent trends.

Multinational enterprises can shift profits across borders to reduce tax burdens, but quantifying this practice and designing effective policy responses remain challenging. Drawing on academic research, this analysis examines the evidence for profit shifting, the mechanisms firms use, variation across companies and countries, and the evolving international policy landscape aimed at curbing these practices.

Corporate tax avoidance remains a central concern in public debate, with claims that multinational companies exploit loopholes to reduce their tax burdens. But much of the evidence cited comes from decades-old data. This analysis examines how international tax rules have fundamentally changed over the past ten years, and asks whether policy discussions have kept pace with regulatory reforms already in place.
