I filed my self assessment for 2024-25 yesterday.
When I got to the section about do you have any foreign income, I clicked on the "no" button and a message popped up, which has never happened before, saying "are you sure, we know you have an overseas bank account".
This is true - it is to pay utility and other bills for my holiday apartment. It is a Euro current account, does not earn any interest, and I do not rent the apartment out. The account is funded by transfers from my UK bank account. I can only assume that EU banks must have started sending details to HMRC of their UK customers.
My question is: do I need to tell HMRC that I own an overseas property, and do I need to provide bank statements to prove I have no foreign income? TIA
