Fifty-one days before large UAE businesses must start sending every B2B invoice through the e-invoicing system, the Ministry of Finance has changed four of the rules they have been building to. Ministerial Decision No. 197 of 2026 took effect on 1 October and was announced on 19 October. Two of the changes save real work. One is easy to misread, and if you are VAT-registered it probably gives you less time than the headlines suggest.
TL;DR: Ministerial Decision 197 of 2026 changed four UAE e-invoicing rules from 1 October 2026. VAT group transactions are excluded for 24 months from 1 January 2027. The deadline becomes 14 business days, but VAT registrants mostly keep the VAT Law's 14 days. Data can now be stored outside the UAE, and system failures no longer need reporting to the FTA.
What Did Ministerial Decision 197 of 2026 Change?
It amends Ministerial Decision No. 243 of 2025, the rulebook for the Electronic Invoicing System, in four practical ways (Ministry of Finance, 2026). It adds intra-group transactions to the list of excluded transactions, changes "14 days" to "14 Business Days", drops the words requiring storage "within the State", and repeals Article 12, which made you notify the Federal Tax Authority (FTA) of a system failure within 2 business days.
The timetable did not move. Businesses with annual revenue of AED 50 million or more still go live on 1 January 2027 (Deloitte, 2026). Everyone else follows on 1 July 2027 and in-scope government entities on 1 October 2027 (The Invoicing Hub, 2026). The Ministry of Finance publishes the list of Accredited Service Providers you must choose from, and our guide to the ASP appointment deadline covers how to pick one.
Why Tax Groups Get a Two-Year Pause
Supplies between members of the same VAT tax group are now excluded transactions for 24 months starting 1 January 2027, so until 31 December 2028. The decision defines a tax group by reference to the VAT Law: two or more persons registered with the FTA as a single taxable person.
That definition matters. A corporate tax group is a separate registration, and being one does not get you this exclusion. Only companies inside a VAT group qualify. Sales from any group member to outside customers stay fully in scope from your go-live date.
The pause is temporary, and the clock starts on 1 January 2027 for everyone. A smaller group that goes live in July 2027 gets 18 months of relief, not 24. You can still send intra-group e-invoices voluntarily. The decision keeps the rule that voluntary issuers fall outside the penalty regime, which makes the window a low-risk time to test group billing.
Does the 14 Business Day Deadline Apply to You?
Probably not for your standard sales, if you are VAT-registered. The new clause 5 of Article 6 gives issuers 14 business days from the date of the transaction, but it is expressly "subject to Clause 4", and clause 4 says a VAT registrant must issue within the timeline in the VAT Law. For a supply that needs a VAT tax invoice, that is 14 days from the date of supply under Article 67 of the VAT Law (Gulf News).
So the business-day count helps in-scope businesses that are not VAT-registered, and registrants on transactions that need no VAT tax invoice. Some summaries published since 19 October describe it simply as an extension. On our reading of the text, a VAT registrant's ordinary sales gain nothing, and we would plan to the VAT deadline.
Fines attach to invoices that never go through the system rather than to late ones. Under Cabinet Decision No. 173 of 2026, each e-invoice not issued and transmitted costs AED 100, up to AED 5,000 a calendar month, with a separate cap of the same size for credit notes (Ministry of Finance, 2026). Late invoices still matter for VAT, so don't treat the gap as slack.
Can You Now Store E-Invoice Data Outside the UAE?
Yes, as far as your own records go. Article 11 used to require invoices, credit notes and associated data to be stored "within the State". The new wording only requires you to keep them for the period the Tax Procedures Law sets and to be able to produce them to the FTA on request.
For businesses running a cloud ERP hosted in Europe or elsewhere, that removes the need for a UAE-hosted copy built only for Article 11. Your ASP's accreditation carries its own data-handling conditions, and data protection law or sector rules for banks and healthcare can still apply, so check those before you cancel anything.
The retention period itself is unchanged, and it is usually longer than finance teams assume. We explain how far back the FTA can look in our post on the FTA audit window and record retention. In our experience, businesses test their backups far more often than they test pulling out one specific invoice on request. So test retrieval as well as backup.
What Happens Now When the System Goes Down?
You no longer have to tell the FTA. Article 12 and the definition of "System Failure" are gone, and Cabinet Decision 173, the current penalty table, carries no fine for an unreported failure. One reporting step is gone.
Nothing replaced it, though, and the decision contains no rule that pauses the issue deadline while your ERP or your provider is offline. Assume the clock keeps running. That shifts the risk into your contract with your Accredited Service Provider (ASP). A question worth asking now is what happens if the provider fails on the last day of the month. The answer sits in the service level agreement. Ask your ASP for its uptime commitment, how it queues invoices during an outage, and how quickly it clears the backlog once it is back.
Five Things to Do Before 1 January 2027
If you are in the first phase, make these changes before go-live rather than after:
- Confirm whether your companies sit in a VAT tax group by checking the group registration in EmaraTax, and tell your ASP so intra-group invoices are excluded from mandatory transmission.
- Set your ERP's e-invoicing deadline to the VAT Law's 14 days if you are VAT-registered, not to 14 business days.
- Ask your IT team or ERP provider where e-invoice data is hosted, and drop any UAE-only storage build if no other rule requires it.
- Run a test request: pick an invoice from three months ago and time how long it takes to produce it with its associated data.
- Add outage handling to your ASP contract, covering uptime, invoice queuing and a named contact.
For the wider mandate, including the roughly 50 mandatory data fields (KPMG, 2026), see our UAE e-invoicing guide. Failing to implement the system at all costs AED 5,000, then AED 5,000 a month, capped at AED 50,000 in any 12 months under Cabinet Decision 173.
Frequently Asked Questions
When did Ministerial Decision 197 of 2026 take effect?
It came into force on 1 October 2026, and the Ministry of Finance announced it on 19 October 2026. The tax group exclusion runs separately, from 1 January 2027 to 31 December 2028.
Are free zone companies in a VAT group covered by the exclusion?
Yes, if they are members of the same VAT tax group. The exclusion depends on VAT group membership, not on licence type. Free zone businesses have no general exclusion from e-invoicing, so their sales to customers outside the group stay in scope.
Does the tax group exclusion change our VAT returns?
No. Supplies within a VAT group are already disregarded for VAT. The exclusion only means you do not have to issue and transmit those invoices through the e-invoicing system for 24 months.
Has the 1 January 2027 go-live been delayed?
No. Decision 197 left the dates alone. Businesses with revenue of AED 50 million or more go live on 1 January 2027, and the rest on 1 July 2027.
Who benefits from the 14 business day deadline?
Mainly in-scope businesses that are not VAT-registered. For supplies that need a VAT tax invoice, registrants still issue within the VAT Law's 14 days from the date of supply, because the new clause is expressly subject to that rule.
If you want to check whether your group structure qualifies for the exclusion, or need your invoicing deadlines and ASP contract reviewed before 1 January, talk to our team.
