1) it is not illegal but very difficult given banking rules and banks own policies 2) if you could get an account getting your salary in would be fine but if you are tax resident and submitting a return you need to look at the DTV with the country where your income earned and tax is being witheld. Take it from there.
Nope, you need to get a remote VA or whatever. Thailand has announced they want Thai's in the gig economy etc to pay tax. It could be attracting unwanted attention to yourself. If you are hiring Thai you and they should be paying Social Security. Hiring a freelancer at arms length through a foreign company might be a way as long as the Thai is totally legit but this is getting complex. Take the path of least resistance.
I did not do it in Jomtien as a tenant. However, my pal owns a condo and goes down and does it and they do not send him away. I went down once as a tenant and they chased me saying "No need, same address" 🙂 I have moved to Chiang Mai and they need it 100% - luckily my agent does it. Just need to message on "Line" and I get the PDF soon after.
Anonymous participant Check local requirements. They are all different. Even as tenant I did not in Jomtien going back to same address. In Chiang Mai it has to be done
