That is a good example IMHO - where one might be inappropriately subject to taxation. In such a case, one would need to make an extra effort to show such funds were covered already by a Double Tax Agreement between one's source country (and Thailand) or extra effort to prove such funds were covered by Thai ministerial directives PAW.161/162 (and were pre-1-Jan-2024 savings). ... Having to keep internal records to document that would be a bit of an annoyance given the funds were never intended to be (in practice) remitted to Thailand as the end destination of the funds. And it further illustrates that a Thai based Wise account/card is not very suitable for use outside of Thailand if the source of one's funds is not Thailand. Only LTR visa holders (such as LTR-WP or LTR-WGC) don't have to be concerned about the taxation aspect. ... But even they (LTR visa holders), if using a Thai based Wise account, get 'hit' with the double conversion fee (ie say Euros > Thai Baht > Hong Kong dollars ). ... So the 'Thai' based Wise account is more limited, than say a 'Germany' based Wise account.
