How to fix BR-CO-15
Invoice total amount with VAT (BT-112) = Invoice total amount without VAT (BT-109) + Invoice total VAT amount (BT-110).
What this rule checks
This cross-check rule ensures that the total amount with VAT equals the sum of the net total and the VAT amount. It catches arithmetic errors in the invoice totals. The three values must be consistent: TaxInclusiveAmount = TaxExclusiveAmount + TaxAmount. Even a one-cent rounding difference will trigger this error.

How to fix it
Recalculate <cbc:TaxInclusiveAmount> = TaxExclusiveAmount + TaxAmount (from the <cac:TaxTotal> with the document currency).
Common causes
- A rounding error causes the three totals to not add up exactly.
- The VAT amount was calculated on individual lines and the sum differs from the document-level VAT total.
- One of the three amounts was manually overridden to an incorrect value.
- Currency amounts use more than two decimal places, causing precision mismatches.
Example: before (broken)
<cac:LegalMonetaryTotal>
<cbc:TaxExclusiveAmount currencyID="EUR">1000.00</cbc:TaxExclusiveAmount>
<cbc:TaxInclusiveAmount currencyID="EUR">1200.00</cbc:TaxInclusiveAmount>
<cbc:PayableAmount currencyID="EUR">1200.00</cbc:PayableAmount>
</cac:LegalMonetaryTotal>
<cac:TaxTotal>
<cbc:TaxAmount currencyID="EUR">210.00</cbc:TaxAmount>
</cac:TaxTotal>
<!-- Error: 1000.00 + 210.00 = 1210.00, not 1200.00 -->Example: after (fixed)
<cac:LegalMonetaryTotal>
<cbc:TaxExclusiveAmount currencyID="EUR">1000.00</cbc:TaxExclusiveAmount>
<cbc:TaxInclusiveAmount currencyID="EUR">1210.00</cbc:TaxInclusiveAmount>
<cbc:PayableAmount currencyID="EUR">1210.00</cbc:PayableAmount>
</cac:LegalMonetaryTotal>
<cac:TaxTotal>
<cbc:TaxAmount currencyID="EUR">210.00</cbc:TaxAmount>
</cac:TaxTotal>
<!-- Correct: 1000.00 + 210.00 = 1210.00 -->Related rules
