BR-S-02

An Invoice that contains an Invoice line (BG-25) where the Invoiced item VAT category code (BT-151) is "Standard rated" shall contain the Seller VAT Identifier (BT-31), the Seller tax registration identifier (BT-32) and/or the Seller tax representative VAT identifier (BT-63).

What does this rule mean?

A line is standard rated but no seller tax identifier (BT-31, BT-32 or BT-63) is present.

With standard rating the seller must be identifiable for tax purposes.

Official rule message (standard)

An Invoice that contains an Invoice line (BG-25) where the Invoiced item VAT category code (BT-151) is "Standard rated" shall contain the Seller VAT Identifier (BT-31), the Seller tax registration identifier (BT-32) and/or the Seller tax representative VAT identifier (BT-63).

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

  • /ubl:Invoice | /cn:CreditNote

CII

  • //rsm:SupplyChainTradeTransaction/ram:IncludedSupplyChainTradeLineItem/ram:SpecifiedLineTradeSettlement/ram:ApplicableTradeTax[ram:CategoryCode = 'S'][upper-case(ram:TypeCode) = 'VAT']

Technical test

The rule passes when this Schematron expression holds true:

/rsm:CrossIndustryInvoice/rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeAgreement/ram:SellerTradeParty/ram:SpecifiedTaxRegistration/ram:ID[@schemeID = ('VA', 'FC')] or /rsm:CrossIndustryInvoice/rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeAgreement/ram:SellerTaxRepresentativeTradeParty/ram:SpecifiedTaxRegistration/ram:ID[@schemeID = 'VA']

How to fix it

Touches amounts, VAT or IBAN. We never change these automatically — correct them in your source data.

Add the seller VAT identifier (BT-31), tax registration identifier (BT-32) or tax representative VAT identifier (BT-63).
