E-invoicing in the UAE: DCTCE 5-corner model, PINT AE, TDD reporting and scenarios for customers.
The United Arab Emirates (UAE) are rolling out mandatory e-invoicing in phases, based on the Peppol network. The UAE model is officially called DCTCE (Digital Continuous Transaction Controls for E-invoicing) and is notable for being one of the first countries outside Europe to fully implement the Peppol 5-corner model, including real-time tax reporting.
The legal basis is Federal Decree-Law No. 16 of 2024, an amendment to the VAT law that took effect on 1 November 2024. The phased rollout starts mid-2026, beginning with large enterprises and government suppliers.
0242:000773The UAE architecture follows the Peppol 5-corner model. Invoices are exchanged in a decentralized way via Peppol, while tax data is simultaneously reported to the government. Each party in the model has a clearly defined role:
The key difference from the standard Peppol 4-corner model is that both the sender's Access Point (C2) and the recipient's Access Point (C3) send a Tax Data Document to the FTA. As a result, the tax authority receives invoice data from both sides, enabling a 100% match.
For each invoice, the Access Point generates a Tax Data Document (TDD AE) containing the VAT-relevant data. This document is sent to the FTA in parallel with the invoice exchange. The TDD does not contain the full invoice content, only the data the tax authority needs for verification.
If the Access Point detects a validation error, a Tax Data Status (TDS) with error information is sent instead of a TDD. The FTA then receives an error report rather than invoice data, making it clear that the transaction was not completed successfully.
The TDD AE specification (v1.0.2) is mandatory as of 27 January 2026. The accompanying invoice format PINT AE (v1.0.3) is mandatory as of 8 April 2026.
PINT AE is the UAE-specific variant of the Peppol International Invoice, based on EN 16931 with additional fields for the UAE tax system. Mandatory fields include the TRN (Tax Registration Number) of both supplier and customer, VAT specifications and currency code AED.
Each invoice contains a UUID that makes the invoice traceable in the FTA system. This ensures that every transaction is uniquely identifiable, even for subsequent corrections or credit notes.
In addition to invoices and credit notes, PINT AE also supports self-billing documents. With self-billing, the buyer issues the invoice on behalf of the supplier. This is relevant in sectors where this practice is common, such as the oil and gas industry.
Depending on where the sender and recipient are based, different rules apply. Below you will find the guidance for each scenario.
Do you invoice companies in the UAE? Then Peppol offers a direct and compliant route. The eConnect PSB supports PINT AE and automatically routes invoices to UAE recipients via the Peppol network. The transformation from your existing invoice format to PINT AE is handled automatically.
Do you have a branch in the UAE? Then you should connect to an accredited Peppol Access Point in good time. Each group member in a VAT group needs its own endpoint. Accredited Service Providers are required to offer a free basic e-invoicing product for small businesses.
Are you a foreign supplier without Peppol? The UAE recipient can process invoices manually for now, but Peppol adoption is strongly recommended. As the phased rollout progresses, electronic exchange will become the norm.
