This article examines the United States' position as the world’s leading tax haven, highlighting its provision of secrecy and low or zero tax rates for nonresident aliens.

This article explores how the US global intangible low-taxed income (GILTI) regime creates tax asymmetries that influence foreign investment incentives. It provides empirical evidence showing that US multinational enterprises reduce foreign operational risks by consolidating operations in foreign headquarters, particularly in developing countries, as a response to GILTI’s taxation of volatile foreign cash flows. The findings suggest these tax-induced costs do not lead to significant policy benefits, such as reductions in foreign intangible assets. The article’s insights are relevant for potential reforms to GILTI and the implementation of the OECD's global tax framework.
