What is the interest withholding rate between Japan and Portugal?
Under the Japan-Portugal tax treaty, the withholding rate on interest is 5%. Certain types of interest (such as government bonds) may qualify for additional exemptions under specific treaty articles. This 5% rate compares to a median of 10% across Japan's 47 active treaty partners, and 10% across Portugal's 28 active partners.

Important: Treaty rates require proper claim forms (e.g., IRS Form W-8BEN for U.S. treaties, HMRC DT-Individual for U.K. treaties, CRA Form NR301 for Canadian treaties) filed before payment. Limitation on Benefits (LOB) provisions may restrict eligibility. A 0% withholding rate does not mean no tax — the residence country may still tax the income. This is not tax advice.
