How to fix ibr-073 in UAE e-invoicing

What is ibr-073?

ibr-073 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 delivery information and belongs to the Dates & periods rule group. An e-invoice that fails ibr-073 is rejected by the Accredited Service Provider gateway before it reaches the FTA.

What the official rule says

A date MUST be formatted YYYY-MM-DD in (ibt-002), (ibt-007), (ibt-009), (ibt-026), (ibt-072), (ibt-073), (ibt-074), (ibt-134), (ibt-135).
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 the delivery information of your UBL 2.1 invoice: 

cbc:IssueDate | cbc:DueDate | cbc:TaxPointDate | cbc:StartDate | cbc:EndDate | cbc:ActualDeliveryDate
