I noticed that missing some VAT rates for Italy.
Also, the fiscal year is wrong.
Have a look here: Fiscal year - Wikipedia
I fixed it through this PR: https://github.com/frappe/erpnext/pull/22806
Issue here: https://github.com/frappe/erpnext/issues/22815
Is still pending for review since several days
It would be nice if someone review that PR so next installations we (Italians) don’t need to fix everything by hand after setup.
