Netherlands – Portugal Tax Treaty
The Netherlands-Portugal tax treaty caps withholding on dividends at 10% for portfolio investors and 5% for qualifying direct investment, and interest at 10%. Royalties are taxed at a uniform 10% across all categories. Private pensions are taxable only in the country of residence, with no withholding at source. This is one of 49 active treaties in Netherlands's network and one of 28 in Portugal's. The general dividend rate of 10% is below the median in both countries' treaty networks (Netherlands: 15%, Portugal: 15%).
