Do dependents need to meet the income requirement for a Thai DTV visa?

I did mine in Taipei. Used the same 500k for me and my 2 children

Used the same account for us all and the same amount. I didn’t increase the amount per person. As others said, may be dependent upon the embassy.

I guess it depends on the embassy. In Paris 500k was enough for my daughter and I

Yes I had my 500k plus 2m for wife and 3 children

Depends on the embassy you're applying through. Also the age of the children should be considered. Teenagers cost more to take care of. I'd definitely show a strong long term balance of at least a 1-1.5 million baht, along with your sponsorship letter. There is no income requirement but there is a funding requirement, and each individual applies for their own Visa and pays the fee. First the primary holder and once that Visa has been granted it's referred to for the dependants applications.
