The facts. Luxembourg and the United States have signed a new tax treaty aimed at eliminating double taxation and preventing tax evasion. The agreement introduces reduced withholding tax rates on dividends, interest, and royalties, and includes provisions for the exchange of tax information between the two countries. This treaty is set to replace the previous agreement from 1996, reflecting modern international tax standards.
Why it matters for international business. The new treaty is significant for international investors and fund managers, as it reduces tax barriers and enhances transparency between Luxembourg and the United States. Lower withholding tax rates can improve after-tax returns on cross-border investments, making Luxembourg an even more attractive jurisdiction for structuring investments into the US. Additionally, the agreement's provisions align with OECD standards, reinforcing Luxembourg's commitment to international tax compliance.
