If you don't want the remaining loopholes to be closed, you better don't discuss this on a public forum
Well, as somebody mentioned before: We donīt try to find a solution
to
hide from the authorities or avoiding to pay tax by trying
"not to be there officially", but use the legal framework to its max.
The rules have changed, fine, but if there is some 183day threshold to cross
and my/their residence is somewhere in another (third) country it is really
interesting to know if this affects your final tax liability in Germany.
