Do my wife and I need separate THB800,000 accounts for our OA retirement visa applications?

Having read both your post and the replies you have received none have mentioned the tax implications that came into force this year. I would strongly advise you research this

Do as Jan has suggested it works better.

don’t use O-A if you plan to settle down in Thailand. Use a normal O visa. If you use O-A you’ll need to maintain an expensive health insurance also in the future when you apply for your yearly extension of stay. Personally I would have applied for a Non O visa at home before you leave. Then you can use your own bank/income statements at home to verify your (monthly) income and you’ll easily be able to open a bank account in Thailand to apply for your extension of stay after 90 days. As your embassy don’t provide a letter to verify your income in Thailand you’ll both need 800 thb for the first year extension of stay. For the second year you can switch to the income method with 12 months transactions over sea to verify your income as I guess you already know.

800,000b each. No more piggy backing

Are you applying for the 1 year non-OA (only available from the Thai embassy in your home country by showing money in your home country bank account along with health insurance) or are you applying for the 90 day non-O visa (can be done from your home country or from Thailand)?
