The e-invoicing UAE will be deployed on the Open Peppol network, utilizing a decentralized continuous transaction control model with a five-corner structure to aid a secure and streamlines data exchange, resulting in accuracy through efficiency.
To sustain this initiative, the UAE issued Decree-Law 16-2024, revising the Value Added Tax (VAT) law to introduce key elements such as e-invoicing, the Electronic Invoicing System, the Tax Reporting Mechanism, and a secure storage system for electronically issued invoices. The decree further mandates that specific technical specifications, schemas, conditions, and procedures for invoice issuance will be detailed in a separate regulation, which is to be finalized by the end of 2024 and implemented by the second quarter of 2025.
