The Spanish Government has approved a special incentive to disclose untaxed cash amounts (black money) at a special 10% rate, without further interest, penalty and/or tax investigations.
This will allow residents and non residents alike to bring into the Spanish system any amount of undisclosed cash held anywhere in the world.
The constitutionality of this measure is to be seen and I personally have many other questions such as the procedure to be followed, KYC and compliance with international anti money laundering regulations.
An interesting way to open the Pandora box. Keep watching this space!
