Fatal — invoice rejected Amounts & totals UAE-specific rule PINT-AE 2026.5

How to fix ibr-104-ae in UAE e-invoicing

What is ibr-104-ae?

ibr-104-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 each invoice line and belongs to the Amounts & totals rule group. An e-invoice that fails ibr-104-ae is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

An Invoice line (IBG-25), where Line VAT Information (IBG-30) is present then Invoice line amount in AED (BTAE-10) and VAT Line amount in AED (BTAE-08) must be provided.
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.
