The UAE changed its e-invoicing rules on 19 October 2026. Ministerial Decision No. 197 of 2026 takes invoices between members of the same VAT tax group out of scope for two years from 1 January 2027, drops the requirement to store e-invoices inside the UAE and removes the system-failure notice. The deadlines did not move.
The Ministry of Finance announced the decision on 19 October, but it took effect from 1 October 2026. It amends Ministerial Decision No. 243 of 2025, the main rulebook for the e-invoicing system. A second decision, Ministerial Decision No. 168 of 2026, changed how service providers get accredited. Below is what each change says, and what it means if your invoices come out of Odoo.
The dates are the same
Start here, because it is the part people hope has changed. It has not.
- Revenue of AED 50 million or more: appoint an Accredited Service Provider (ASP) by 30 October 2026 and issue e-invoices from 1 January 2027.
- Everyone else: appoint by 31 March 2027 and go live on 1 July 2027.
The penalty for having no appointed provider or working system is still AED 5,000 a month, and late invoices or credit notes still cost AED 100 each, up to AED 5,000 a month. If you want the whole picture first, UAE e-invoicing on Odoo covers it.
Change 1: invoices inside a tax group are excluded for 24 months
A tax group is two or more businesses registered with the Federal Tax Authority as one taxable person for VAT. The decision now adds that definition and lists, as an excluded transaction, any business transaction between members of the same tax group, for 24 months starting on 1 January 2027. In plain terms, invoices between group members do not have to go through the e-invoicing system until the end of 2028.
Two details matter. First, you can still choose to send those invoices as e-invoices. If you do, the rules apply to them in full, except the penalties. Second, only invoices between group members are excluded. Anything a group member invoices to a customer outside the group is in scope as before.
What it means in Odoo
Groups usually run several companies in one Odoo database, often with inter-company rules that create the matching bill automatically. Those inter-company invoices are exactly the flow this change covers. Three things to do:
- List every company in the database and mark which ones are members of the same VAT group. Your tax adviser confirms the list, not the software.
- Decide whether you will send group-internal invoices to your ASP anyway or hold them back. Holding them back means fewer documents and lower volume; sending them means one process for everything. Both are allowed.
- If you hold them back, the connector needs a clear rule: skip invoices where both the seller and the buyer are members of the same group, and send everything else. Test that rule with a real inter-company invoice before go-live.
Write the end date down too. The exclusion is temporary, so the same flow has to be ready to go through the ASP from January 2029.

Check Your Odoo for E-InvoicingChange 2: e-invoices no longer have to be stored in the UAE
Article 11 of the rulebook was rewritten. It now says you must keep all e-invoices, e-credit notes and their associated data for the period set by the Tax Procedures Law, and make sure they can be produced to the Federal Tax Authority on request. The Ministry says the change removes the earlier requirement that the data be stored within the UAE, so the focus moves from where records sit to whether you keep them and can hand them over.
What it means in Odoo
If you run Odoo Online, Odoo.sh or your own servers outside the country, the e-invoicing decision no longer pushes you to move them. What you still need is a complete archive you can retrieve quickly:
- Keep the XML file your connector sends, and the provider’s response, attached to the invoice record in Odoo, not only in the provider’s portal.
- Ask your provider how you export the full archive if you ever leave them, and in what format.
- Check your backups cover those attachments, not just the database.
The decision only removes the e-invoicing storage rule. Other rules, a customer contract or a sector regulator can still have their own location requirements. That is a question for your adviser.
Change 3: the system-failure notice is gone
Under the original rules, if your e-invoicing system failed you had to tell the Federal Tax Authority within two business days, and the penalty schedule attached AED 1,000 a day to missing that notice. Ministerial Decision No. 197 of 2026 repealed Article 12 and deleted the definition of “System Failure”. From 1 October 2026 there is no notice to file.
What it means in Odoo
If your go-live plan had a step for notifying the authority, remove it. But keep the monitoring. Invoices that cannot be issued while something is broken still move towards the late-issue penalty, so somebody should see quickly when documents stop going out. In Odoo that can be as simple as a saved filter on posted invoices that have not been sent to the provider, checked every day by a named person.
Change 4: the 14-business-day window, restated
The decision also restates the timing rule in Article 6. An e-invoice or e-credit note must generally be issued and transmitted through the e-invoicing system within fourteen business days from the date of the transaction. The clause refers to another part of the same article, so read it with your adviser for unusual cases.
What it means in Odoo
The risk is not a slow system. It is invoices that sit in draft, credit notes raised weeks after a dispute is settled, and documents that bounce because a customer has no TRN or an emirate is typed rather than coded. Our guide to emirate code validation in Odoo covers one of the most common causes. The penalty side is in UAE e-invoicing penalties.
Providers: from pre-approval to accreditation
Ministerial Decision No. 168 of 2026, also in force from 1 October 2026, replaced the earlier decision on service providers. Instead of a preliminary approval followed by accreditation, providers are now accredited directly, and only after passing the Ministry’s assessment and testing. Published summaries list the steps as an eligibility assessment, interoperability testing, checks on how the provider onboards customers, and test reporting of tax data to the Federal Tax Authority. The Ministry then lists accredited providers in its official register. Reports say providers that held a preliminary approval were given 30 days from 1 October to meet the new requirements.
For you, the action is simple. Before you sign or renew, check that your provider appears in the Ministry of Finance register of accredited providers. Do not rely on an older approval letter. Our guide on how to choose an Accredited Service Provider covers the rest of that decision.
What did not change
- The format: invoices are still PINT AE structured XML. PINT AE explained covers what that file contains.
- The route: Odoo sends the invoice to your provider, which passes it to your customer’s provider and reports it to the authority. Odoo never connects to the authority directly.
- One provider: you still appoint a single ASP.
- The data work: TRNs on customers, emirate codes on addresses, one tax category per Odoo tax, and every channel that issues invoices, including POS and your website.
Odoo itself has not caught up either. Odoo 20 does not include UAE e-invoicing, so you still need a connector between Odoo and your provider.
What to do this week
If you are in the first group, 30 October is six days away. Appoint your provider, and check it is on the accredited register when you do. Then go back through your Odoo setup with the four changes above: mark your tax-group companies, decide how group invoices are handled, attach the sent files to the invoice records, and take the system-failure step out of your plan.
If you are in the second group, nothing here changes your timeline, but it may shrink your scope. Fewer documents through the ASP can mean a smaller plan. Our connector pricing and cost calculator takes one question: how many documents you send a month.
Nothing here is tax or legal advice. The text comes from Ministerial Decision No. 197 of 2026 as published by the Ministry of Finance, and from the Ministry’s announcements. Have your adviser confirm how it applies to you.
