How to fix ibr-126 in UAE e-invoicing

What is ibr-126?

ibr-126 is a fatal validation rule in the UAE's Peppol PINT-AE e-invoicing specification, inherited from the shared Peppol layer. It is checked against the VAT totals and belongs to the Amounts & totals rule group. An e-invoice that fails ibr-126 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

All currencyID attributes must have the same value as the Invoice currency code (ibt-005), except for amounts expected to be in Tax accounting currency (ibt-006).
UAE impact: this is a fatal rule from the shared Peppol layer, enforced in the UAE profile — an invoice failing it is rejected at the Accredited Service Provider gateway before it ever reaches the FTA. A rejected invoice means resubmission delays, and late transmission risks the AED 100-per-invoice penalty under Cabinet Decision No. 106 of 2025.

Where it applies

This rule is checked against the VAT totals of your UBL 2.1 invoice: 

cbc:Amount | cbc:BaseAmount | cbc:PriceAmount | cbc:LineExtensionAmount | cbc:TaxExclusiveAmount | cbc:TaxInclusiveAmount | cbc:AllowanceTotalAmount | cbc:ChargeTotalAmount | cbc:PrepaidAmount | cbc:PayableRoundingAmount | cbc:PayableAmount | cac:TaxTotal[cbc:TaxAmount/@currencyID=/*/cbc:DocumentCurrencyCode]/cbc:TaxAmount | cac:TaxTotal[cbc:TaxAmount/@currencyID=/*/cbc:DocumentCurrencyCode]/cac:TaxSubtotal/cbc:TaxableAmount | cac:TaxTotal[cbc:TaxAmount/@currencyID=/*/cbc:DocumentCurrencyCode]/cac:TaxSubtotal/cbc:TaxAmount
