Purchase tax - based on cadastral value or purchase price?
We recently bought a house (September 2011) expecting the tax to be calculated on the catastal value which we were told is always less than the purchase price so worked out a worst case scenario and expected to be a little pleasantly surprised. When the bill came through with projected costs a few days before it was clear the costs were based on the purchase price. No mention of the catastal value at any point. I am still reading frequently that these purchase taxes are based on the catastal value. What are others' experiences of this? We were anticipating taking up residence within 18 months but a change of circumstances might mean this could not happen in which case we need to tell the tax office before the 18 months are up and pay the difference before drumming up fines so it would be good to know how much extra we will be paying by knowing what figure to base this on. Basically who decides which figure you base your purchase taxes on...the actual purchase price or catastal value?
