Fatal — invoice rejected Amounts & totals Shared Peppol rule PINT-AE 2026.5

How to fix ibr-124 in UAE e-invoicing

What is ibr-124?

ibr-124 is a fatal validation rule in the UAE's Peppol PINT-AE e-invoicing specification, inherited from the shared Peppol layer. It is checked against the VAT totals and belongs to the Amounts & totals rule group. An e-invoice that fails ibr-124 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

Invoice total TAX amount (ibt-110) MUST have no more than 2 decimals.

UAE impact: this is a fatal rule from the shared Peppol layer, enforced in the UAE 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.
