What it means
The rule checks cac:TaxCategory in each document-level cac:TaxTotal/cac:TaxSubtotal for cbc:TierRange. It applies to UBL invoices and credit notes. The tier range describes the band to which a tiered tax rate applies. It is separate from the VAT rate (BT-119), which, where applicable, is given in cbc:Percent.
Why it matters
EN 16931 does not use a tier range on the tax category in a document-level tax subtotal.
How to fix it
Delete cbc:TierRange from cac:TaxCategory under each document-level cac:TaxTotal/cac:TaxSubtotal. Keep any applicable VAT rate in cbc:Percent. Recheck the file.
