So it has nothing to do with the tax table? Even if interest is mentioned there (2D)? They take out this tax since I have the account, so it's not about being a "tax resident" or not?
Sure, that they will take it? I tried that years ago... the Embassy in Germany wasn't really happy with the idea to get a certificate from a Thai doctor.
Listen... I just tell you my own experiences... nothing else. You don't have to take it too serious, okay? You are free to do whatever you want. But... why you not just split your transfers and avoid all these problems? There's no need to transfer the 800k in one step, nobody here care about that, not your bank, not the immigration. For them it's all about the seasoning, not about in how many portions you transfered the money.
Yep... you are right... the German Embassy/Consulates still provide these certificates. For the Embassy you need an appointment, the Consulates do it by "walk in".
