You only think they say this, but a retirement visa doesn’t exist. So you can not need something which doesn’t exist.
Now, there is something which is called a non-o visa based on retirement.
You need this visa to get a bank account (there are other possible visa, but let’s stick with “retirement).
The visa is valid for 90 days. After that you need an “extension of stay based on retirement”. Not a visa, but a permit to extend your stay for one year.
You need the 800k bank balance for 2 months to be able to request the extension.
Now, I ask you: Where did you see “retirement visa”?
Since you are answering on Facebook and you’re suggesting that you can’t get usable information on Facebook we can all safely assume that your comment is useless. 🤣🤣🤣
I went one week before the expiration date. No worries. The IO sent us away because the photos were not according to the local-national requirements.
We went again the next day, with obviously a new bank balance letter from the bank and all went well.
Note that we went for “marriage extension” and they heavily try to discourage that. “When you would do retirement extension it would be done in 10 minutes” the lady repeatedly said.
She is really a very friendly and helpful lady. No passport photos? She will take her mobile and generate them. Too many forms? She will do them for us. Sign here!
But wedding extension…
Nonetheless, done within a week before non-o expiration. No worries.
There is no “double taxation”. That is exactly what DTAs are for. Thailand *may* charge slightly more on your income in which case you *might* have to pay a small additional charge.
That said, many portions of US income are exempted from Thai taxation, such as US social security.
We have a special interest group with nearly 1,000 members on the topic. The group features (among others) a group of expert users consisting of a US tax lawyer who is married to a Thai tax lawyer.
In a few weeks members of the SIG can participate in a Q&A session with another licensed tax lawyer.
