Unfortunately many of those staying longer have been using illegal Airbnb accommodation, self-cateriing, and not putting as much money into the overall economy. These people are supposed to be tourists, but many are trying to live here instead
I was saying that most countries you can still use the income affidavit method, which means 65k does not have to be transferred into a Thai bank account. To my knowledge only US, UK and Australia can't use this method
I just looked up the US DTA and it appears under Article 20 that Social Security payments are taxable only in the US, so any SS money you transfer to Thailand will not be taxed in Thailand.
I'm Australian. "Pensions" paid in Australia are not taxable in Thailand. I don't know about Social Security. You will need to read and absorb your country's DTA
If you're talking about taxes in Thailand, read and absorb the DTA relevant to your country. Chances are if you are importing pension money you will pay zero
