Warning

UBL-CR-296: The tax representative's care-of flag should be left out

In short

Warning: worth checking.

UBL-CR-296 means the file includes a MarkCareIndicator for the seller's tax representative, which EN 16931 does not use. Remove the flag, export the file again and recheck it.

On this page

What it means

The seller's tax representative (BG-11) acts for the seller in VAT matters. This rule checks that cac:TaxRepresentativeParty has no cbc:MarkCareIndicator, a yes or no flag from the general UBL party model. The standard only has the tax representative's name (BT-62), VAT number (BT-63) and postal address (BG-12).

Why it matters

EN 16931 calls for this flag to be left out of the seller's tax representative details. This warning does not establish acceptance or how the recipient handles the flag.

How to fix it

Delete cbc:MarkCareIndicator from cac:TaxRepresentativeParty in the exported XML. If you cannot control the export, ask your software supplier to omit this element. Export the file again and recheck it.
