Ireland: The Revenue Commissioners in Ireland are using Google Street View and Maps to check up on those who may have undervalued their homes to reduce their level of Property Tax. Revenue officials are mapping out every property in Ireland in order to highlight those owners whose homes are valued significantly below those of their neighbors. "This is an effective tool in looking at individual property valuations and a very cost effective tool,” said Michelle Carroll, Revenue. The nationwide map, which is being created by Revenue, will be for official use only. The map will also show the identity of the homeowners in question and their PPS numbers. "If people think they have undervalued, they will have an opportunity to correct the value online. People can self-correct without fear of interest and penalties until the end of this month," added Ms Carroll.
