How to fix aligned-ibrp-ae-06 in UAE e-invoicing

What is aligned-ibrp-ae-06?

aligned-ibrp-ae-06 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 allowances and charges and belongs to the VAT categories & rates rule group. An e-invoice that fails aligned-ibrp-ae-06 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

In a Document level allowance (ibg-20) where the Document level allowance VAT category code (ibt-95) is "Reverse charge" the Document level allowance VAT rate (ibt-96) MUST be 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 allowances and charges of your UBL 2.1 invoice: 

cac:AllowanceCharge[cbc:ChargeIndicator=false()]/cac:TaxCategory[normalize-space(cbc:ID)='AE'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='VAT']
