What is the interest withholding rate between Luxembourg and United States?

The Luxembourg-United States tax treaty reduces the withholding rate on interest payments to 0%. This means interest paid between residents of these two countries is exempt from withholding tax at source. This is particularly beneficial for cross-border debt financing and bank deposits. The 0% rate still requires proper documentation — it does not apply automatically. Interest is fully exempt — Luxembourg has 15 such treaties in its network.
