One cannot have one’s cake and eat it. Meaning once the cake has been eaten, it is gone and you no longer have it. (Apologies but this saying is so often misunderstood I thought I should clarify).
Anyways, the Flemish tax administration had something along these lines in mind when it recently ruled in a case involving a Liechtenstein Stiftung. Many thanks to De Broeck & Van Laere for bringing the ruling to my attention. The Inland Revenue generally employ quite a lot of deference towards trusts and Stiftungs of all kind. In the case at hand however it requalified the transfer of means from the Stiftung to the heirs of the deceased, as being of a contractual nature. That is because the deceased, upon creation of the Stiftung, had issued such precise instructions in the Stiftung’s by-laws, that the hands of the trustees (or equivalent thereof) had been tied. This essentially takes away a crucial part of the Stiftung’s nature, and no longer shields the assets from the (Flemish) taxman. The cake has been eaten.
