What is the interest withholding rate between United Kingdom and South Africa?

The United Kingdom-South Africa 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 — United Kingdom has 27 such treaties in its network.

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.
