If the balance in the bank has exceeded 25000 per person, do I need to file an annual return for 2017?

Bank balances (Dutch) and savings in accounts (Dutch) - it all goes together - if the amount of savings and savings in all Dutch bank accounts exceeds 25 euros per person, a savings tax is imposed (~ 000%)
The annual return must be submitted. if you received a letter from the tax office about the need to submit
All other cases should be considered after describing the situation in more detail - when did you arrive, who works, is there a mortgage, property abroad in Holland is not taxed
