In Italy we have as in Spain and Portugal special tax apart from VAT called withholding tax (“retention vat” in MediusFlow).
It is handled by adding a special tax code called retention VAT separate from VAT in the coding
This code is created with standard tax function in MediusFlow in the tax settings. So no special fields but standard tax code fields.
However in selection for creating reports in report function there is only a selection for VAT code but not for other codes and using this selection it exports only the VAT code.
For reconciliation and accrual reporting it would be useful to have all kind of tax codes coded on line level available.
