Fatal — invoice rejected VAT categories & rates UAE-specific rule PINT-AE 2026.5

How to fix aligned-ibrp-z-05 in UAE e-invoicing

What is aligned-ibrp-z-05?

aligned-ibrp-z-05 is a fatal validation rule in the UAE's Peppol PINT-AE e-invoicing specification — one of the UAE-specific rules. It is checked against each invoice line and belongs to the VAT categories & rates rule group. An e-invoice that fails aligned-ibrp-z-05 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

In an Invoice line (ibg-25) where the Invoiced item VAT category code (ibt-151) is "Zero rated" the Invoiced item VAT rate (ibt-152) MUST be 0 (zero).
UAE impact: this is a fatal rule specific to the UAE PINT-AE 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 each invoice line of your UBL 2.1 invoice:

cac:InvoiceLine/cac:Item/cac:ClassifiedTaxCategory[normalize-space(cbc:ID) = 'Z'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='VAT'] | cac:CreditNoteLine/cac:Item/cac:ClassifiedTaxCategory[normalize-space(cbc:ID) = 'Z'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='VAT']
