Peppol BIS Billing 3.0, May 2026 release, EN 16931 model bound to UBL

Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.

## Plain-language reading

The Invoice total VAT amount in accounting currency (BT-111) may have at most 2 decimals. The statement says "allowed maximum number of decimals" and "is 2", and it ends with a period. It does not say shall. The context is the invoice or the credit note. This is a decimal limit, not the BR-53 presence check. The published test reads cbc:TaxAmount whose currencyID equals the tax currency code, with spaces around =. It writes <=2 with no space before <= and no space after the comma. The absent branch is not(...) and does not call exists.

## What to change

Send the Invoice total VAT amount in accounting currency (BT-111) with at most 2 digits after the decimal point.

## Illustration

Illustration of the condition in the official statement. Not an example published by the source.

**Fails the stated condition.** The invoice total VAT amount in the accounting currency has 3 digits after the decimal point.

**Passes the stated condition.** That amount has 2 digits after the decimal point.

(//cac:TaxTotal/cbc:TaxAmount[@currencyID = cbc:TaxCurrencyCode] and (string-length(substring-after(//cac:TaxTotal/cbc:TaxAmount[@currencyID = cbc:TaxCurrencyCode],'.'))<=2)) or (not(//cac:TaxTotal/cbc:TaxAmount[@currencyID = cbc:TaxCurrencyCode]))
