The United Arab Emirates (UAE) has taken a decisive step toward fully digitalizing its tax administration with the release of new Ministerial Decisions and amendments to the VAT Executive Regulation. These legislative updates confirm the scope, phased implementation timeline, and key compliance requirements for the nation’s new Electronic Invoicing System (EIS).
The changes signal a transformative shift toward a standardized, real-time digital reporting model, aligning the UAE with global best practices for tax compliance.
Key Legislative Updates
On September 29, 2025, the Ministry of Finance (MoF) issued Ministerial Decisions No. 243 and 244 of 2025, clarifying the operational framework for the EIS. Concurrently, Cabinet Decision No. 100 of 2025 amended Articles 59 (Tax Invoices) and 60 (Tax Credit Notes) of the VAT Executive Regulations, setting the stage for the mandatory adoption of e-invoicing.
- Scope of Application (Ministerial Decision No. 243)
The e-invoicing system applies to all Business-to-Business (B2B) and Business-to-Government (B2G) transactions conducted by persons operating in the UAE.
Inclusions and Exclusions:
- Included: All B2B and B2G transactions.
- Excluded: Business-to-Consumer (B2C) transactions (until further notice) and transactions related to the sovereign activities of government entities.
Mandatory Use of Accredited Service Providers (ASPs): - Both the issuer and the recipient of an electronic invoice or credit note are required to appoint a Ministry-accredited Accredited Service Provider (ASP). The ASPs will be critical for ensuring the invoices are validated, compliant, and transmitted securely through the system.
- All e-invoices and e-credit notes must contain the full set of data fields as prescribed by the FTA’s technical specifications and must be stored securely within the UAE.
- Amendments to the VAT Executive Regulation (Cabinet Decision No. 100)
The amendments to the VAT Executive Regulation (Cabinet Decision No. 52 of 2017, as amended) eliminate previous flexibilities and standardize compliance for the digital era:
- Elimination of Simplified Invoices: The concept of simplified invoices (for supplies below AED 10,000) is eliminated. All e-invoices must now be full, structured tax documents.
- Mandatory E-Invoicing for Zero-Rated Supplies: Issuing a full tax invoice for wholly zero-rated supplies (e.g., direct exports) is now mandatory, ensuring a complete and auditable digital trail.
- Tax Credit Notes: Credit notes must be issued electronically and comply with the full e-invoicing data schema.
- Input Tax Recovery: A new condition for input VAT recovery requires the taxable person to retain the tax invoice in the specified electronic format.
Phased Implementation Timeline (Ministerial Decision No. 244)
The EIS will be rolled out in a structured, phased approach, with deadlines staggered based on a business’s annual revenue. Voluntary adoption of the system is open to any business starting from July 1, 2026.
Key Implementation Deadlines: - Pilot Program: The system will commence with a pilot program for a selected Taxpayer Working Group starting July 1, 2026.
- Phase 1: Large Businesses (Annual Revenue equal or more than AED 50 Million)
- ASP Appointment Deadline: July 31, 2026
- Mandatory E-Invoicing Deadline: January 1, 2027
- Phase 2: Other Businesses (Annual Revenue less than AED 50 Million)
- ASP Appointment Deadline: March 31, 2027
- Mandatory E-Invoicing Deadline: July 1, 2027
- Phase 3: All UAE Government Entities
- ASP Appointment Deadline: March 31, 2027
- Mandatory E-Invoicing Deadline: October 1, 2027
A Decentralized, Secure Model
The UAE’s system adopts a decentralized 5-Corner Continuous Transaction Control and Exchange (DCTCE) model, which is based on the international Peppol network standard. This model enhances security and data integrity by requiring all transactions to pass through an Accredited Service Provider (ASP). The ASP validates the data, transmits it securely to the recipient’s ASP, and reports key information to the Federal Tax Authority (FTA) in near real-time, creating an immediate and secure audit trail.
Call to Action for Businesses
The legislative foundation for the e-invoicing mandate is now firmly in place, making preparation a critical priority. Businesses operating in the UAE are strongly advised to: - Assess Systems: Conduct a readiness assessment of current Enterprise Resource Planning (ERP) and invoicing systems.
- Appoint an ASP: Identify and engage a Ministry-accredited Accredited Service Provider to handle the technical implementation and compliance.
- Review Master Data: Ensure all customer and vendor master data (including VAT Registration Numbers and addresses) is complete and accurate, as the simplified invoicing relief is no longer available.
- Integrate: Work with the ASP to map ERP data fields to the required UAE e-invoicing data dictionary and integrate the necessary APIs for real-time transmission and reporting.
