The Ministry of Finance changed the UAE e-invoicing rules 2026 through Ministerial Decision No. 197 of 2026, which took effect on 1 October. Transactions between tax group members are excluded for 24 months from 1 January 2027, invoice data no longer has to be stored in the UAE, and the system-failure notice is repealed.
*Quick answer: What changed in UAE e-invoicing in October 2026? Ministerial Decision No. 197 of 2026, effective 1 October, does three things. It excludes transactions between VAT tax group members for 24 months from 1 January 2027. It removes the requirement to store e-invoice data in the UAE. It repeals the duty to notify the Federal Tax Authority of a system failure within two business days.*
Key takeaways
- Tax groups get breathing space: invoices between members of the same tax group are excluded for 24 months from 1 January 2027.
- Storage is now location-neutral: you must keep records for the legal period and produce them on request, but not necessarily inside the UAE.
- System-failure reporting is gone: the two-business-day notice to the FTA no longer applies.
- Deadlines have not moved: large businesses still go live on 1 January 2027.
What is Ministerial Decision No. 197 of 2026?
Ministerial Decision No. 197 of 2026 is an amendment to Ministerial Decision No. 243 of 2025, the main rulebook for the UAE Electronic Invoicing System. According to the Ministry of Finance, announced on 19 October 2026, it clarifies certain requirements and reduces operational burdens on businesses. The decision came into force on 1 October 2026.
Definitions used in this guide
- Tax group: two or more persons registered with the Federal Tax Authority (FTA) as a single taxable person under the VAT Law.
- Excluded transaction: a business transaction that does not have to go through the e-invoicing system.
- Accredited Service Provider (ASP): a provider approved by the Ministry of Finance to send, receive and validate e-invoices, and to report data, in the UAE system.
- Electronic Invoicing System: the national system built on a five-corner model, in which each party connects through its own ASP and tax data is reported to the FTA.
What exactly changed in the e-invoicing rules?
Three provisions changed, and the rest of the framework stays in place. The table below compares them.
| Area | Before (Decision 243 of 2025) | After (from 1 October 2026) | What to do |
|---|---|---|---|
| Tax group transactions | Not listed as an exclusion | Excluded for 24 months from 1 January 2027 | Map intra-group flows and plan for outside-party invoices |
| Invoice data storage | E-invoice data had to be stored in the UAE | Retain for the Tax Procedures Law period and produce on request; location rule removed | Review hosting, backups and vendor contracts |
| System failure | Notify the FTA within two business days; defined term | Article 12 repealed; definition deleted | Keep your own incident log and an ASP outage process |

How does the tax group exclusion work?
Transactions between members of the same tax group are treated as excluded transactions for 24 months, starting 1 January 2027. By our calculation, that period runs to 31 December 2028 [VERIFY end date with the FTA]. The decision text also says a person may issue and report e-invoices voluntarily for excluded transactions. If they do, the system rules apply to them, but the violation and penalty decisions do not.
The exclusion covers only dealings between group members. Invoices to customers, and from suppliers, outside the group stay in scope. The Ministry of Finance said the measure gives businesses more flexibility and time to adapt.
The Tax Group Exposure Check (illustrative)
To see how much of your invoicing is still in scope, use this formula:
In-scope share (%) = (total invoices minus intra-group invoices) divided by total invoices, times 100
Illustrative example only: a group issues 2,000 invoices a month. Of these, 600 are between group members, so 1,400 are in scope. The in-scope share is 70 per cent. Even with the exclusion, most of this group's invoicing still has to work through an ASP.
The decision does not say whether each member of a tax group needs its own ASP connection for outside-party invoices. Ask your ASP and the FTA [VERIFY].
Can you now store e-invoice data outside the UAE?
Yes, under this decision. The Ministry of Finance removed the earlier requirement that e-invoice data be stored within the UAE, shifting the focus to whether records are retained and can be accessed for tax compliance.
The amended Article 11 sets two duties for anyone subject to the system:
- Retain all electronic invoices, electronic credit notes and associated data for the period set by the Tax Procedures Law. This is generally five years, with longer periods for some records [VERIFY current retention periods].
- Be able to produce those records to the FTA on request.
The change does not remove your other legal duties. Check data protection rules (such as the UAE Personal Data Protection Law), sector regulator requirements, client contracts and your cloud vendor's terms before moving data offshore. Plan for fast retrieval, because the duty to produce records stays.
What happened to system failure reporting?
The duty to notify the FTA of a system failure within two business days no longer exists. Article 12 of Decision 243 of 2025 was repealed, and the definition of system failure was removed from Article 1.
That does not make outages harmless. The amended text still says invoices and credit notes must be issued and transmitted through the system within 14 business days of the transaction. The decision does not say how late invoices caused by an outage will be treated, so confirm this with your ASP and the FTA [VERIFY]. Keep an internal incident log and agree outage support terms with your ASP.
What are the current UAE e-invoicing deadlines?
The deadlines for the main phases were not changed by Decision 197. Large businesses must appoint an ASP by 30 October 2026 and go live on 1 January 2027, according to Sovos, Banqup and Deloitte summaries of the rules.
| Phase | Who | Appoint an ASP by | Go-live |
|---|---|---|---|
| Pilot / voluntary | Taxpayer working group and voluntary adopters | Not applicable | 1 July 2026 |
| Phase 1 | Annual revenue of Dh50 million or more | 30 October 2026 (extended from 31 July 2026) | 1 January 2027 |
| Phase 2 | Annual revenue below Dh50 million | 31 March 2027 | 1 July 2027 |
| Phase 3 | Government entities | 31 March 2027 | 1 October 2027 |

What should businesses do now?
Start with the ASP, because the Phase 1 appointment deadline of 30 October 2026 is only days away. Then work through the rest of the UAE E-Invoicing October 2026 Readiness Checklist below.

| 2 | Appoint an Accredited Service Provider from the Ministry's list | Finance and IT | Phase 1 by 30 Oct 2026 |

What are the penalties for non-compliance?
Penalties are set in separate decisions, not in Decision 197. Secondary sources such as VAT IT report fines of Dh5,000 a month for failing to implement the system or appoint an ASP on time, and Dh100 per invoice (capped at Dh5,000 a month) for late issuing [VERIFY against the current penalty decision and FTA guidance]. Under the decision text, voluntary e-invoicing for excluded transactions does not attract these penalties.
What we do not know yet
- Whether each tax group member must have its own ASP endpoint for outside-party invoices.
- How late invoices will be treated when caused by an outage, now that system-failure rules are repealed.
- Whether the FTA will publish practical guidance on tax group invoicing during the 24-month exclusion.
- The exact retention period that applies to each type of invoice record.
We will update this article as new guidance appears.
Conclusion and next step
Decision 197 gives businesses more room on tax group invoices, data storage and outage reporting, but it does not move the main deadlines. If you are in Phase 1, appoint your ASP now and start testing before 1 January 2027.
