I am often asked which expenses can be detracted from income in Italy. These serve to reduce your potential tax liabilities.
Unlike a lot of countries where allowances are offered on a certain amount of income each year (e.g. the UK and the first £12500), Italy does not offer any such allowance, but instead uses a complicated system of detractions and deductions of certain living expenses. That list covers a multitude of items, such as eco bonus for re-construction work to your home, funeral expenses and medical expenses.
A new criteria that has been imposed as of 2020 is that a number of these must now be paid only by traceable means of payment (bonifico, bancomat or credit card). If they are not paid with one of these methods then they are not deductible.
The following table, taken from an article in Sole24Ore is a good reference tool to see which expenses can be deducted, at what % of the total cost and whether they can be paid in cash or not.
I hope you find it useful. If you are not claiming for any that you might be eligible for then I would advise you have a conversation with your commercialista about them.
