More hot air! I have said this all through the last 18 months or so since it was announced as "proposed new tax regulations". Unless I missed something and despite the dates being quoted for this to commence being banded about, the change to the tax laws need to be announced in the Royal Gazette. I have never seen anyone say more than "if, might, when" on this subject and to "collect your data just in case".
To quote: "Carden admitted such matters remain unclear. He acknowledged the Revenue Department’s intent to widen the tax base, with small earners inadvertently caught in policies aimed at wealthy Thais" is significant as it shows this was not intended to include foreign nationals who reside in Thailand long term. If your country has a mutual Tax Agreement, unless you are moving LARGE amounts through your Thai bank account it is unlikely to effect you.
