Warning

UBL-CR-602: A line's VAT category should not carry a tier range

In short

Warning: worth checking.

UBL-CR-602 means the VAT category of an item on an invoice or credit note line has a tier range (cbc:TierRange), which EN 16931 does not use. It is a warning. Remove the element and keep the VAT category code (BT-151) and any applicable VAT rate (BT-152).

What it means

The rule looks at the item on every invoice line (or credit note line) in a UBL file. It warns when the item's VAT details (cac:ClassifiedTaxCategory) contain a cbc:TierRange, which describes a band of amounts for a tiered tax. This rule checks only for that element, not whether a VAT rate (BT-152) is present or valid.

Why it matters

EN 16931 does not use a tier range within a line's classified tax category.

How to fix it

Check the export mapping of your invoicing software for a tier range in the line's VAT category and omit that element from the export. If you build the XML yourself, delete cbc:TierRange from cac:ClassifiedTaxCategory under cac:InvoiceLine/cac:Item (cac:CreditNoteLine in a credit note). Keep cbc:ID, any applicable cbc:Percent and cac:TaxScheme.
