Nope not one cent at the moment - I have structured my business appropriately to minimise future impacts.
Guys like you really have ZERO idea when it comes to land tax. It is a PERCEIVED wealth tax nothing more. How would you like to own investments where you could end up paying 30% of your income from those investments on a tax you get nothing back on. Then on top of that assuming you still actually make some money you still have to pay normal income tax rates.
The reality is the only ones who like land taxes are the ones that don't have to pay them because they are ignorant of the consequences.
