# BR-IC-09 Intra-community VAT amount must be zero

The VAT category tax amount (BT-117) in a VAT breakdown (BG-23) where the VAT category code (BT-118) is "Intra-community supply" shall be 0.

## Problem Description

The VAT category tax amount (BT-117) in a VAT breakdown (BG-23) where the VAT category code (BT-118) is "Intra-community supply" shall be 0.

> **ERROR**: XRechnung 3.0

## Context and Significance

Because the supply is VAT-exempt at origin, the reported category VAT amount must be exactly zero to match the zero rate.

## Solution

Set cbc:TaxAmount to 0.00 in the K TaxSubtotal (BG-23); the intra-community supply carries no VAT in the seller’s country.
