BR-O-12

What does this rule mean?

The invoice has a breakdown with category "O" (not subject to VAT), but also a line with another VAT category.

An invoice with "not subject to VAT" may only contain lines of that category — the standard does not allow mixing them with taxable supplies.

BG-23

VAT breakdown (group)

BG-25

Invoice line (group)

BT-118

VAT category code (UNCL 5305)

BT-151

Invoiced item VAT category code (UNCL 5305)

Where the rule applies

Syntax: CII · UBL

The same rule, expressed twice: UBL and CII name the same fields with different paths. Running a CII file against the UBL rules is why you get errors that mean nothing.

Technical test

The rule passes when this Schematron expression holds true:

not(//ram:ApplicableTradeTax[ram:CategoryCode != 'O'])

How to fix it

Touches amounts, VAT or IBAN. We never change these automatically — correct them in your source data.

Invoice the taxable lines separately — or correct the category of the line.

Correct the affected entry in your XML, then re-check the invoice. Validation runs locally in your browser — your file never leaves your machine.
