# BR-B-02 Split payment and standard rated cannot appear together

An Invoice that contains an Invoice line (BG-25), a Document level allowance (BG-20) or a Document level charge (BG-21) where the VAT category code (BT-151, BT-95 or BT-102) is "Split payment" shall not contain an invoice line (BG-25), a Document level allowance (BG-20) or a Document level charge (BG-21) where the VAT category code (BT-151, BT-95 or BT-102) is "Standard rated".

## Problem Description

An Invoice that contains an Invoice line (BG-25), a Document level allowance (BG-20) or a Document level charge (BG-21) where the VAT category code (BT-151, BT-95 or BT-102) is "Split payment" shall not contain an invoice line (BG-25), a Document level allowance (BG-20) or a Document level charge (BG-21) where the VAT category code (BT-151, BT-95 or BT-102) is "Standard rated".

> **ERROR**: XRechnung 3.0

## Context and Significance

Split payment (category "B") and standard rated (S) settle VAT differently, so mixing them on one document is disallowed; the split-payment category comes from the updated EN16931 code lists supported by the current XRechnung 3.0.2 rulepack.

## Solution

Keep split-payment (category "B") lines, allowances and charges on a separate invoice from any standard-rated (category "S") ones; do not mix "B" and "S" in the same document.

## Valid Examples

- An invoice whose lines all use category "B" (Split payment), with no "S" line

## Invalid Examples

- One invoice line with category "B" (Split payment) and another line with category "S" (Standard rated) on the same invoice
