Certain types of interest (such as government bonds) may qualify for additional exemptions under specific treaty articles. This 10% rate compares to a median of 10% across South Korea's 48 active treaty partners, and 7% across Singapore's 42 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 β€” the residence country may still tax the income. This is not tax advice.
