Andries Hi! There is no "main" account at bunq, all accounts are equal.
If you enable AutoVAT, you enable it on the sub-account on which you want to receive the VAT. So then you can't enable this on this account itself, only on other accounts.
So let's say you want to receive AutoVAT on sub-account A, then you have to enable it on sub-account A. You can then select sub-account B (and C, and D, etc.). What then happens, is that if a payment is done from sub-account B, the VAT is sent to sub-account A.
