What changed
The UAE Ministry of Finance issued Ministerial Decision No. 197 of 2026, amending the Electronic Invoicing System rules. The decision became effective on October 1, 2026. Its most important practical changes concern tax-group transactions, data storage, and system-failure reporting.
For transactions between persons that are members of the same UAE Tax Group, the rules introduce a temporary exclusion for 24 months beginning January 1, 2027. During that period, those transactions are treated as excluded transactions for the electronic-invoicing framework. This gives related entities additional time to align their systems and processes.
Data storage: location is less important than access
The amendment removes the previous requirement that electronic invoices, electronic credit notes, and related data be stored inside the UAE. However, the underlying compliance obligation remains significant: businesses must retain the records for the period prescribed under the Tax Procedures Law and be able to provide them to the Federal Tax Authority when requested.
This means a business may use an overseas cloud provider, subject to its own security and governance requirements, but it should confirm that:
- Records remain complete and tamper-resistant.
- The retention period is configured correctly.
- UAE tax personnel can retrieve documents promptly.
- Supporting data can be exported in a usable format.
- Vendor contracts preserve access during audits or disputes.
System-failure reporting removed
The amendments repeal the former “System Failure” provisions, including the requirement to notify the Federal Tax Authority within two business days of a system failure. Businesses should nevertheless maintain incident logs, backup procedures, and continuity controls because invoice availability and auditability remain central to tax compliance.
Practical example
Suppose a UAE parent and its wholly owned subsidiary are members of the same Tax Group. From January 1, 2027, qualifying transactions between them can benefit from the temporary exclusion. The group should still document the relationship, transaction flows, tax treatment, and reconciliation process so that the exclusion is applied consistently.
Action checklist
- Map all intercompany transactions before January 2027.
- Review whether tax-group status is current and properly documented.
- Update cloud-storage and disaster-recovery policies.
- Test retrieval of invoices and credit notes from outside the UAE.
- Retain evidence of system incidents even though the specific notification rule was removed.
The amendment is a compliance simplification, not a general waiver of recordkeeping duties. Businesses should treat accessibility, retention, and reliable audit trails as the continuing core requirements.
