BR-E-10

A VAT Breakdown (BG-23) with VAT Category code (BT-118) "Exempt from VAT" shall have a VAT exemption reason code (BT-121) or a VAT exemption reason text (BT-120).

What does this rule mean?

An exempt VAT breakdown (category E) has no exemption reason.

For a VAT exemption the invoice must state the reason — as a code (BT-121) or text (BT-120).

Where the rule applies

Syntax: CII · UBL

The same rule, expressed twice: UBL and CII name the same fields with different paths. Running a CII file against the UBL rules is why you get errors that mean nothing.

UBL

  • /*/cac:TaxTotal/cac:TaxSubtotal/cac:TaxCategory[normalize-space(cbc:ID) = 'E'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='VAT']

CII

  • //rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeSettlement/ram:ApplicableTradeTax/ram:CategoryCode[. = 'E'][upper-case(../ram:TypeCode) = 'VAT']

Technical test

The rule passes when this Schematron expression holds true:

(../ram:ExemptionReason) or (../ram:ExemptionReasonCode)
