Double Taxation Agreement (DTA)

Yes, in most cases you must still declare your Dutch pension in Thailand. Under the Dutch–Thai Double Tax Agreement (DTA), civil service pensions remain taxable only in the Netherlands, but private and occupational pensions can also be taxable in Thailand once remitted into the country. Thailand’s remittance basis means tax is due in the year the money is brought into Thailand, not when it is earned. To avoid double taxation, you may be able to claim a credit for Dutch tax already paid, but this requires proper documentation and timely filing.
