What it means
Every line of the VAT breakdown (BG-23) must contain the VAT amount (BT-117). It is the VAT due for this category and rate, and it is 0 for exempt, zero-rated or reverse-charge supplies.
Why it matters
The VAT breakdown is what the buyer uses to reclaim VAT and what a tax authority checks. Each line of it must be complete, or the invoice is rejected.
How to fix it
Let your invoicing software build the VAT breakdown and export again. If you build the XML yourself, add cbc:TaxAmount to every cac:TaxSubtotal (UBL) or ram:CalculatedAmount to every ram:ApplicableTradeTax (CII), writing 0 where no VAT is due.
The rule as published
Each VAT breakdown (BG-23) shall have a VAT category tax amount (BT-117). Business terms: BG-23, BT-117
