You are checking the All VAT / Sales Tax Items report, however you are missing some customer invoices that have VAT and are posted as well.
This case document is relevant for IT-Italy, which has tax payment deferral.
Reproducing the Issue
- Go to Tax Management work center
- Go to Lists
- Open All VAT / Sales Tax Items
- Execute the report so that the tax due date covers the related customer invoice dates.
You'll notice that some customer invoices that have VAT are not being retrieved in this report.
The missing customer invoices are posted with the checkbox for Tax Payment Deferral checked, so the VAT will be posted first to a deferred tax account and moved to the normal VAT account once the invoice is paid/cleared. After that, the invoice will also be picked up for reporting.
In order for the invoices to show up for reporting, the documents need to be paid/cleared.
Note that once the invoice is posted, there is no way to change the deferred tax indicator anymore. If the invoices are incorrect an cannot be reversed, you may create credit memos for all incorrect invoices.
You can also adjust the payment deferral settings via fine-tune activity Tax on Goods and Services – Italy
