One caution ... based on my reading but not based on any Thai brokerage experience. If you buy Thai Depositary Receipt (DR) of say a US stock via a Thai brokerage, any profit made on such for a Thai tax resident is not nominally taxable in Thailand, since the DR is listed on the Stock Exchange of Thailand (SET). However I believe (and others can PLEASE correct me if i am wrong) if one who is a Thai tax resident, through a Thai brokerage, is able to trade directly on foreign equities in a foreign stock exchange, then those profits if remitted into Thailand after 31-Dec-2023 would be taxable in Thailand (possibly dependent on DTA of the country (of the stock exchange company) with Thailand. Hence to trade foreign equities using a Thai brokerage, the way to do that may best be visa Thai Depositary Receipt (DR) of the foreign company stock/equity. However not all foreign companies thou have a DR. Likely a limited select number of DRs for USA based companies has the largest selection. Again - I may have this wrong - its based on my reading (and hopefully others correct me). In my case, using my citizenship status, I trade with a Canadian brokerage, and I rely on the Canada-Thai DTA and my LTR-WP visa status to legally manage my taxation exposure. I believe depending on one's nationality and the location of one's brokerage, there are other ways to also legally manage one's tax exposure - but I have not researched such.
