Does having two Thai bank accounts with a total of 80k baht monthly qualify for the retirement visa requirement?

I suppose its possible, once you get confirmation letters from Bank 1, to transfer some funds to Bank 2 and quickly get letters from them. Not suggesting that OP has that in mind. Just that the "one bank account" rule might be to prevent the above.

No — for the retirement extension, immigration requires the 65,000 THB/month to be deposited into the same Thai bank account each month from abroad. Splitting it between two accounts (50k + 30k) won’t meet the rule unless you consolidate into one account before the monthly deposit deadline.

I have two accounts. Transfer from US into one and then transfer to the other. Like Tod said, if you make them do twice the work, they may nit pick you to death.

No

well seeing as the monthly total is OVER the 65K baht a month threshold required it would indeed meet the financial requirements.

Obviously that's if you have transfers to those 2 accounts, each month, every month for the previous 12 months before you go to apply for an extension

AND

You would have to have updated the bank books of those accounts the day you applied, got the 'standard' bank letters and year detail transaction reports from the bank on both those accounts.

it's DOUBLE the paperwork for you (and for the officer to check thru) so be ready to get some grief over it 😕

There is nothing in the rules that says it has to be all in a single account, just that the monthly total in a thai bank account in your name only is 65K baht per month.

I remember some one reported a while ago that their office let them do it and told them next year, all in one account.
