BR-E-1
Exempt VAT: Exemption Reason Missing (BT-120/BT-121)
What This Error Means
When VAT category E (Exempt from VAT) is used, the invoice must include either an exemption reason text (BT-120) or an exemption reason code (BT-121) in the TaxCategory. Without this, auditors cannot verify the legal basis for not charging VAT.
Why this happens
BR-E-1 fires when a tax breakdown uses VAT category E (exempt) but provides neither an exemption reason text (BT-120) nor an exemption reason code (BT-121). Because an exempt supply charges no VAT, the law requires a stated legal basis so that tax auditors can verify why VAT was not applied. The error appears when software emits category E but leaves the reason blank, or when an exempt and a reverse-charge case are conflated (reverse charge is category AE, not E).
How to Fix It
Add cbc:TaxExemptionReason and/or cbc:TaxExemptionReasonCode to the cac:TaxCategory element. Common German examples: 'Reverse Charge § 13b UStG', 'Innergemeinschaftliche Lieferung § 4 Nr. 1b UStG'.
Step-by-step
1) Add a TaxExemptionReason (BT-120) text and/or a TaxExemptionReasonCode (BT-121) to the cac:TaxCategory with ID 'E'. 2) Use the legal basis that actually applies, e.g. 'Innergemeinschaftliche Lieferung, § 4 Nr. 1b UStG' for an intra-community supply, or the applicable § 4 UStG exemption. 3) Keep Percent at 0 for category E. 4) Verify you are using the right category: small business (§19) and genuine exemptions use E; reverse charge uses AE; intra-community goods may use K. 5) Re-validate.

What counts as a valid exemption reason?
A reference to the legal basis for the exemption, as free text (BT-120) and/or a VATEX code (BT-121). Examples: '§ 4 Nr. 1b UStG' for an intra-community supply, or the § 19 UStG reference for a small business.
Is exempt (E) the same as reverse charge (AE)?
No. Category E is a genuine VAT exemption; category AE is the reverse charge mechanism where the buyer accounts for the VAT. Using the wrong one causes validation and tax-reporting problems.
