Why This Error Matters

Invoice will be rejected. VAT exempt (category E) transactions must follow specific rules including zero rate and seller tax identification.

BR-E-02 is a hard failure. Invoices that trigger this rule are rejected at the access point and never reach the recipient. In Peppol networks, this means your sending system receives an MLR (Message Level Response) with a rejection status. The invoice must be corrected and re-sent, adding delay to your payment cycle.
