Regarding due dates, we should differentiate between VAT returns and VAT payments.
Italian monthly VAT calculations must be paid by the 16th day of the month following the reporting period. Quarterly VAT calculations must be paid by the 16th day of the second month following the reporting period for the first three calendar quarters of the year. The fourth quarter VAT return is due by 16 March.
As a general rule, quarterly VAT calculations follow the calendar quarter (January to March, April to June, etc).
For example, the second quarter VAT calculation of 2017 is due by 16 August 2017. Your VAT payment must reach the tax authorities bank account by the same due date.
If the due date falls on a Saturday, Sunday or bank holiday, the date is shifted to the next working day.
In addition to monthly or quarterly VAT payments, an annual prepayment must be made by the 27 December.

When the taxpayer is paying VAT quarterly, the amount due should be increased by 1% to pay for index price fluctuations.
Quarterly VAT returns including VAT ledgers are required as from 1 January 2017. The due date to submit this return is the end of the second month following the reporting period. There is a holiday extension foreseen for the second quarter VAT return, which will be due by 16 September of the following year.
The due date for Annual VAT returns is 30 April of the following year. The 2016 Annual VAT return will still be submitted by the former due date: 28 February 2017.
