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

How to fix aligned-ibrp-s-10 in UAE e-invoicing

What is aligned-ibrp-s-10?

aligned-ibrp-s-10 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 the VAT totals and belongs to the VAT categories & rates rule group. An e-invoice that fails aligned-ibrp-s-10 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

A VAT breakdown (ibg-23) with VAT Category code (ibt-118) "Standard rate" MUST not have a VAT exemption reason code (IBT-186) or VAT exemption reason text (IBT-185).

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 the VAT totals of your UBL 2.1 invoice:

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