I only know that living in the Netherlands you have to register, bankacvount, ID everything. Our security number is the gateway to everything about your life including finances. Tax is a part of it and with me they automatically charhge, they know my earnigs. If I lose it's my bad luck if I would win I get billed or they take it from my income. Taxes always go first.
Better eat you never know when it's the last time. I hope it works out fine for you. If not play stupid and cry if needed. If it works for others why not for you.
Perhaps the internet can tell you how they know or if someone told them. You are not one of the rich guys. 💕
