All tax and social security rules of Thailand apply to your employer, if you stay there longer than 186 days. He is responsible to comply to every rule. So most employers limit remote work to EU countries. As a freelancer it's your own duty to follow the law, the client just pays the bills you send.
yeah like me, who stays in Thailand in the winter and Europe in summer. 6 months is quite a long time to stay, I think, although not a "live in Thailand" longstay.
For years it was very hard for people under 50 to obtain a longstay visa in Thailand. Now it's very easy. Don't think it will remain that easy in the future, generally. Thai authorities are quick to make changes.
they only wanted a certain amount of money at one time. In my oppinion no smart entrepreneur keeps more than 10K in a normal bank account. But - that is what they wanted. A stock-depot report was not accepted
