There is a confusion here, as there are TWO taxes on your property:
1. The IBI which goes to the local council, this is well knonw, and this is what you are talking about. But there is also a
2. Non-resident property tax that goes to the central tax office!! (as am not allowed to post links, not enough post) have a google search! There is plenty of info aboutthis out there.
This 2nd tax the one that many people don't pay........
