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

How to fix ibr-157-ae in UAE e-invoicing

What is ibr-157-ae?

ibr-157-ae 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 invoice document and belongs to the VAT categories & rates rule group. An e-invoice that fails ibr-157-ae is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

Invoice Transaction-type code (BTAE-02) cannot be XXX1XXXX (Summary invoice) or X1XXXXXX (Deemed supply) or XX1XXXXX (Margin scheme) when the invoice type code (IBT-003) is 'Out of scope of VAT' or 'Credit note related to goods or services'.

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.
