Warning

UBL-CR-485: Leave the tax type code out of discounts and charges

In short

Warning: worth checking.

UBL-CR-485 means the tax scheme in the VAT category of a discount or charge on the whole invoice has a TaxTypeCode, which EN 16931 does not use. Remove cbc:TaxTypeCode and keep the scheme ID VAT.

On this page

What it means

The VAT category of a discount (BG-20) or charge (BG-21) on the whole invoice has a tax scheme. This rule checks that the scheme has no cbc:TaxTypeCode, a UBL element for a code that says what kind of tax it is. The check applies to document-level discounts and charges on both invoices and credit notes.

Why it matters

The EN 16931 UBL representation does not use this additional tax type code in the tax scheme of a document-level discount or charge.

How to fix it

Delete cbc:TaxTypeCode from cac:TaxScheme in the cac:TaxCategory of each cac:AllowanceCharge directly under Invoice or CreditNote. Keep cbc:ID with the value VAT. If your invoicing software writes the tax type code, ask its supplier to leave it out of the export. Recheck the corrected file.
