Imposta non calcolata correttamente (riepilogo)

What it means

In a DatiRiepilogo block the declared Imposta does not match ImponibileImporto x AliquotaIVA / 100 within the rounding tolerance (the SdI allows the difference declared in Arrotondamento, typically a cent or two).

How to fix it

Set Imposta = round(ImponibileImporto * AliquotaIVA / 100, 2). If you intentionally round differently, declare the delta in the Arrotondamento element of the same DatiRiepilogo block.

Example

<AliquotaIVA>22.00</AliquotaIVA><ImponibileImporto>5.00</ImponibileImporto><Imposta>1.10</Imposta>
