- The property was bought many years ago, before leaving Indonesia, when working there as an employee, when also there was no obligation under the law to submit personal tax return at the time (only the employer company was deducting and paying the required tax for the employees)

- In order to sell property in Indonesia a tax number is needed maybe, also for Indonesians not resident in Indonesia?
- Is the Tax Amnesty Protected content PPS) now in effect applicable to Indonesians not resident in Indonesia also, when they have no obligation to submit tax returns in Indonesia? And if yes, what do they need to do to be able to sell their property without any problems?
