Can I withdraw and redeposit funds to meet the 65000 baht monthly requirement for my retirement visa in Thailand?

You need an income of bht , and a confirmation from your embassy that this is your permanent income ..

You can never renew any visa, the visa is used when you enter Thailand, i suppose you had a O-A since it give you 1 year permit to stay, just remember to stay current with the insurance demands and it gives you another year permit in Thailand if you enter before the 1 year limit. Most of us living here apply for a yearly temporary stay on TM 7 ( wich is not a visa) , the financial demands is same for both, but on a O-A your assets can stay in your home country

I’m told you need your Thai bank to provide a document as proof of the 800k or more.

The 65k or more per month, bank verification for 12 consecutive months.

The 800k is the easiest to verify for the bank.

I have a Thai wife … so my marriage visa only requires 400k … I transfer into that account $2300 per mth = around 74k baht per mth and then I withdraw 70k every month and we put that in a separate account for my wife who pays all our bills every mth and grocery & gas etc… we avg about 65k per mth … but at the end of the year I have a book bank book that shows 400k and 12 deposits of 70k+ and 12 withdrawals of 70k to satisfy immigration 👍

Why not just pay an agent? I see many advertisements for baht and they fulfill the financial requirement

Highly likely you’ll need to provide evidence of where the 65,000+ baht per month in passive income is coming from. This could include pension statements, bank statements showing regular pension payments, or documentation of rental income, such as letting agent statements and the corresponding remittances into your bank account.

As John said it is a minimum of 65,000 baht per month from overseas. You are allowed to spend the money on living expenses, but you can't just send it back home and recycle it.

There are 2 options

1. You have 800k baht in a Thai bank account for 2 months before you apply, keep it there for 3 months after you get the extension and never go below 400k baht at any point in the year

2. You transfer into your thai bank account a minimum of 65k baht each month for the 12 months immediately prior to applying for the extension. This 65k baht must come from overseas. I don't think it would take immigration long to work out if you were recycling the money and ask for proof of it's origins.
