Markdown exportBR-CO-15 Invoice total with VAT must equal total without VAT plus total VAT
Invoice total amount with VAT (BT-112) must equal Invoice total amount without VAT (BT-109) plus Invoice total VAT amount (BT-110).
Problem Description
ERROR
EN 16931 calculation and consistency rule (BR-CO)
Context and Significance
Public-sector receiving platforms such as OZG-RE (direct federal administration, more than 170 indirect federal bodies and several Länder) and other state or municipal portals reject invoices whose totals do not add up. The validator adds BT-109 and the VAT total in the invoice currency and compares the result exactly with BT-112. A typical cause is a gross total copied from the PDF while BT-109 or BT-110 was corrected later, or a second VAT total in the invoice currency in UBL.
Solution
Recompute BT-112 = BT-109 + BT-110 from the final values in the file (UBL: cbc:TaxInclusiveAmount; CII: ram:GrandTotalAmount). In UBL, only one cac:TaxTotal/cbc:TaxAmount may use the invoice currency.

Valid Examples
- BT-109 = 100.00, BT-110 = 19.00 → BT-112 = 119.00
- BT-109 = 84.03, BT-110 = 15.97 → BT-112 = 100.00
Invalid Examples
- BT-109 = 100.00, BT-110 = 19.00 but BT-112 = 118.99
- BT-112 = BT-109 (VAT total forgotten in the gross sum)
