BR-S-03

What does this rule mean?

A document-level allowance is standard rated (category S) but the invoice carries no seller tax identifier (BT-31, BT-32 or BT-63).

A standard-rated allowance reduces the tax — whoever reduces it must be identifiable for tax purposes.

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.

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

Correct the affected entry in your XML, then re-check the invoice. Validation runs locally in your browser — your file never leaves your machine.
