A new website indicating property values on which the new property tax will be based has gone live.
Property owners can check what property values are in their area on www.revenue.ie.
The valuations will be based on a variety of sources including the recently established property price register, the An Post geodirectory and stamp duty data.
Other information such as the 2011 Census results and the 2011 Pobal HP Deprivation Index will also be used.
The website divides the country into electoral districts of which there are around 3,000 in the country.
There are between 500 and 1,000 properties in each district.
Revenue says this is not an exact science but the system used works well in the majority of cases.
It also stresses the valuations given on the website are for guidance.
