How to fix ibr-082 in UAE e-invoicing

What is ibr-082?

ibr-082 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 allowances and charges and belongs to the Allowances & charges rule group. An e-invoice that fails ibr-082 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

Allowance/charge indicator value MUST equal 'true' or 'false'.
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.

Where it applies

This rule is checked against allowances and charges of your UBL 2.1 invoice: 

cac:AllowanceCharge
Technical test condition (Schematron) 
normalize-space(cbc:ChargeIndicator/text()) = 'true' or normalize-space(cbc:ChargeIndicator/text()) = 'false'
