We worked for a billionaire in France.
To be paid I had to have a limited company created, in my name, in Portugal and sub-contract my wife as an employee.
I've no idea how much/little tax was saved for my employer and I doubt he knew either, not much. These people employ accountants who are totally obsessed with tax avoidance and congratulate themselves accordingly depending on the intricacies they need to employ. What SAFC have done was handed to them on a plate tbh and turning down the offer, at a time when no one knew how long this crisis would last, would go against their grain.
