might be sensible but it is wrong. Thailand is already from 1st Jan 2024 taxing any income brought into the country... whetever it comes from.
If your country has a really good double taxation agreement there is a chance you won't pay tax in Thailand....but all countries have their own agreements and so you will need to investigate the wording yourself or get advice from a tax specialist.
The UK DTA is pretty useless, and will only help ex-servicemen and certain others like police. For the average person it will not protect you.
I am here on a retirement visa and I am fully expecting to pay tax at the end of March 2025
