PEPPOL-EN16931-P0107
Tax Category AE MUST be used when exemption reason code is VATEX-EU-AE
What does this rule mean?
The exemption reason VATEX-EU-AE is not paired with VAT category AE.
The reason code and the category describe the same fact (reverse charge) — Peppol requires them to agree, otherwise the VAT treatment is ambiguous.
