Yes, but this is a worst case scenario. If the money comes from the sale of a property we can suppose that capital gains may be considered a income and what's let as savings. Some people will pay the capital gains tax in their country of origin, but the amount paid may be higher or lower than than what they would pay here. The DTA will come into the picture and last would Thai RD isolate pre-2024 gains? The mind boggles...So, IMHO, if you want to transfer large amounts in the next couple of years make sure are not resident for the purpose of taxation.
