This dual tax if I've paid UK tax do I have to pay tax in Thailand on the same money? Sending my wife money to buy land, planning on building a house.
TLDR : Answer Summary
The question revolves around whether a UK expat must pay taxes in Thailand on money that has already been taxed in the UK. Most comments suggest that if the money has been taxed before coming to Thailand, and it is not considered income (for example, if it is simply transferred savings or money sent to a spouse), there should generally be no additional tax obligations in Thailand. However, complications can arise based on tax residency status and the specifics of the Thailand-UK double taxation agreement. It is also implied that sending money for property purchases may require understanding the local tax implications, particularly around gift tax and ownership laws.
