The leaked suggestion from the commision on taxation report seems to indicate a move away from large one off taxes (eg stamp duty on houses, VRT on cars) and a move towards something which will give a more certain tax income for the state, ie annual property taxes and a tax on driving(eg congestion charges and increased fuel taxes) and abolishing VRT
Whether or not the Govt will have the liathroidi to do this remains to be seen. The Catch 22 for anyone planning on changing their car and buying a new one is that whilst the price of the new car would drop, the potential trade in price may drop also, likewise the potential price if you go to sell privately
Of course there is nothing in stopping you going into a dealer now and telling him what is in the commission on taxation report on VRT and see is he prepared to do you a deal now rather then let you walk out the door until January, especially if you are a cash buyer
