Can I change banks while on a retirement extension with the 800K requirement in Thailand?

I had to swap banks recently as the local Bangkok bank closed .

Open new kbank account first .

The 800k needs to leave your old account and go into your new account on the same day .

I chose to do this by withdrawing cash so there were no transfer issues.

Do not leave your old account totally empty.

Order a statement for your old bank account 5-7 days wait for Bangkok bank .

When it's time to do the extension order your Kbank statement and letter and take that and your old Bangkok statement to immigration.

I have done an extension since the money move and it was all issue free .

I would say you'd move the money in 'chunks' so that 400K baht was always in one account or the other 🙂 AND don't do any moving of funds during the 2 months before an extension is due OR the 3 months after it's granted <- when you're required to have 800K baht in the account.

After that (when you only need to have a balance of 400K), move the money in two steps, 400K at a time would be the safest 🙂

The next year you would need a print out of the old account statement and the new account statement to show the money trail, but you should be able to do it no issues other than that
