United Kingdom – Japan Tax Treaty
The United Kingdom-Japan tax treaty caps withholding on dividends at 10% for portfolio investors and 0% for qualifying direct investment, and interest at 10%. Royalties are taxed at a uniform 0% across all categories. Private pensions are taxable only in the country of residence, with no withholding at source. This is one of 54 active treaties in United Kingdom's network and one of 47 in Japan's. The general dividend rate of 10% is below the median in both countries' treaty networks (United Kingdom: 15%, Japan: 15%).
