BR-FR-DEC-01_BT-110: Invalid format for the total VAT amount

In short

Fatal: fails the selected checks.

BR-FR-DEC-01_BT-110 means your total VAT amount (BT-110) has an invalid number format. Use at most two decimal places, a dot for decimals and at most 19 characters excluding the dot. A leading minus sign is allowed and counts towards the character limit.

What it means

The check applies to the total VAT amount (BT-110). In UBL, this is cbc:TaxAmount directly inside cac:TaxTotal, not the VAT amount within a cac:TaxSubtotal entry. CII checks the corresponding total VAT field. The rule checks the number format rather than the VAT calculation.

Why it matters

Software needs a readable VAT total when processing your invoice totals. This check does not establish whether the VAT amounts are correctly calculated.

How to fix it

Correct the total VAT amount (BT-110) in your source invoice or export. Use a dot for decimals, remove grouping separators and currency symbols, and limit the value to two decimal places. If rounding changes the amount, check it against the VAT breakdown before regenerating and rechecking the file.
