If you choose not to take advantage of Italy’s flat tax system designed for RBI investors, then the tax treatment will follow general rules according to Italian tax system. Therefore, the tax treatment for your Italian and foreign income will be calculated on the basis of income tax rates valid for any Italian citizen. Hence, as for 2019, you will have to consider five rates, from 23 percent to 43 percent, valid from incomes from 15,000 euros to 75,000 euros or more. Obviously, you will be allowed to deduct any expenses before calculting how much you have to exactly pay and consider also that you would be able to opt for a flat tax if you are entitled.
