Since the stocks in an endowment is not legally owned by me it should probably not be taxable in the philippines, right?
Unless you are a hospital, church, university or some similar institution, you usually are not the recipient or beneficiary of an \"endowment.\" Do you mean \"trust\" or some other type of fund?
At any rate, if the \"fund\" was established outside the RP, and the passive income is paid to you from a source outside the RP, and all you do is transfer monies from your foreign account to the RP... very unlikely you would have any RP tax issues.
