What is the dividend withholding rate between South Korea and Thailand?

Under the South Korea-Thailand tax treaty, the withholding rate on dividends is 10% for portfolio investors (general rate). A reduced rate of 10% applies when the beneficial owner is a company holding a qualifying ownership stake (typically 10% or more of voting stock). Note that the reduced rate requires the recipient to file the appropriate treaty benefit claim form before payment. This 10% rate compares to a median of 15% across South Korea's 48 active treaty partners, and 15% across Thailand's 22 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.
