If you are resident in Italy then you are liable to tax on your worldwide income and worldwide gains. You will be a resident in Italy if you have your home there, if you spend more than 183 days a year there or if you are registered at the Office of Records in Italy. Italy has income tax, capital gains tax, inheritance tax and value added tax, however it does not have a wealth tax. The tax year in Italy is the calendar year. If you do become a tax resident of Italy, it is your responsibility to inform the tax authorities; it is not their job to find you.
Property prices in Italy are usually quoted in ‘euros per square metre’. Like any other property market, in Italy it is impossible to give a definitive guide to what prices should be in any given town or region – with great diversity in the type, age, size, condition and location of property it is very difficult to give an accurate ‘like for like’ comparison.
