BR-CO-17: VAT amount of a category is calculated wrongly
A rule from EN 16931. What the message means and how to fix it.
What the message means
For each VAT category: tax amount (BT-117) = taxable amount (BT-116) × rate (BT-119) ÷ 100, rounded to two decimals.
How to fix it
Calculate the tax once per category from the summed taxable amount, not as the sum of tax amounts rounded per line. Small cent differences almost always come from there.
Where the field is in the file
- UBL:
cac:TaxTotal/cac:TaxSubtotal (cbc:TaxableAmount, cbc:TaxAmount, cac:TaxCategory/cbc:Percent) - CII:
ram:ApplicableHeaderTradeSettlement/ram:ApplicableTradeTax (ram:BasisAmount, ram:CalculatedAmount, ram:RateApplicablePercent)
The rule applies to every format built on EN 16931: Peppol BIS Billing 3.0, XRechnung, ZUGFeRD and Factur-X, and other national CIUS.
