The Italian authorities have further clarified the deduction rights of VAT on expenses. Expenses paid in 2017 must be claimed by April  of the following year, but an exception is now granted for 2017 expenses that the invoice is received in the following year. For example, if an expense invoice is received 2018 you will have until the end of 2018 to claim the expense even though the expense is relevant to 2017. This obviously applies to very few transactions but could be useful in certain cases.
