Bangkok Bank will email the twelve month statement. I've done it for the last two years extensions. Much better than the clunky old system where you had to go into the branch, order the statement, then return five days later to pick it up. It's now delivered within a few hours to your email. Print it and take it to immigration for your extension. Too easy. Thank you Bangkok Bank!
I know what he means but those days are drawing to a close. Bangkok Bank already insist on four months the lump sum has to be in the account otherwise no letter! The other banks will follow suit! Already accounts are being frozen across the country and Facebook is packed full of whiney expats who can't get their money! lol
I'm the same. I live in Thailand 7-8 months of the year, rest of the time I'm travelling. However, the point I was making is there's no value in counting days. For the last 15 years I've been in Thailand for more than 180 days a year, and yet I've never had to pay a single baht in tax on money I've brought in, and never had to file a tax return
