South Korea – Thailand Tax Treaty
The South Korea-Thailand tax treaty caps withholding on dividends at 10%, and interest at 10%. Royalty rates vary by category, from 10% on copyright to 15% on film and television. Private pensions are taxable only in the country of residence, with no withholding at source. This is one of 48 active treaties in South Korea's network and one of 22 in Thailand's. The general dividend rate of 10% is below the median in both countries' treaty networks (South Korea: 15%, Thailand: 15%).
