In principle a well-functioning property taxation system should be a key part of a predictable revenue stream for sustainable funding of public services. This has many benefits, not least of which are lower interest rates demanded on Irish debt by the bond market.
The annual property taxes paid by every property in the country should be published online. People should be able see what others are paying. Those who are overpaying should be able to see that this is the case and take action. Tax cheats should be exposed. The system must be fair, but must be seen to be fair.
Publishing of property tax data would also help the dysfunctional housing market. House-buyers would be in a position to see the house valuation used by sellers. If a seller thinks their house is "worth" 500k, is that the valuation they are using for tax purposes? If it is, the buyer can have some confidence that the asking price is justified. Slowly, this would help confidence to return to the market but at realistic price levels.
Publishing of all property tax data. Take the spoofing out of the property market.
