# BR-Z-10 — Zero rated (Z): no exemption reason allowed

> https://billhorse.com/en/rules/br-z-10/

## What does this error mean?

A VAT breakdown of category Z (zero rated) must not contain an exemption reason (BT-120/BT-121) — zero rating is not an exemption.

## How to fix it

Remove the exemption reason or choose the appropriate category (E, AE, K, G).
