Double Taxation Treaty NL-PT
The Netherlands and Portugal have a tax treaty (DTT) to avoid double taxation. Main points: • Government pension (ABP): usually taxed only in the Netherlands • Private pension: usually taxed in Portugal • Rental income from Dutch real estate: taxed in the Netherlands • Dividends: withholding tax in country of payment + credit • Capital gains: depends on type and treaty Always consult a tax advisor familiar with both Dutch and Portuguese tax law. The interaction between the two systems is complex.
