## Official rule text

Invoice total VAT amount (BT-110) = Σ VAT category tax amount (BT-117).

## Why did my invoice fail BR-CO-14?

The Invoice total VAT amount (BT-110) must equal the sum of the VAT category tax amounts (BT-117) from every VAT breakdown group. This ensures the single grand-total VAT figure reconciles exactly with the per-VAT-category breakdown.

## Common causes

- TaxTotal/TaxAmount (BT-110) computed independently from the per-category TaxSubtotal/TaxAmount values (BT-117).
- Missing or extra VAT breakdown (BG-23 / cac:TaxSubtotal) so the sum no longer matches.
- Rounding the grand total differently from the sum of already-rounded category amounts.
- A VAT category tax amount stored with wrong sign or wrong value.

## How do I fix it?

```
Set the document-level TaxTotal/TaxAmount to the sum of every TaxSubtotal/TaxAmount. E.g. subtotals of 21.00 and 4.90 → <cbc:TaxAmount currencyID="EUR">25.90</cbc:TaxAmount>.
```
