I live and work in the Netherlands. My 30% ruling is about to end during this year (2021) so for the current year's income tax return I will be asked to declare all my foreign bank accounts.
I am beneficiary on a couple of joint bank accounts that belong to my mother and father. I did not earn a single euro on those but my name is added on these bank accounts (it is extremely common in my country of origin, an EU country). When I declare these bank accounts, the Dutch tax authorities include the question "what share of the capital in the account is mine". Is the capital divided equally among the beneficiaries? I.e., if the bank account has X eu, and 3 beneficiaries, should i declare X/3 that belongs to me, or simply zero (because none of these are mine, my mother and father worked and have been taxed on those)?
Any clarification is appreciated.
