UAE e-invoicing has a new date for the biggest businesses: those with revenue of AED 50,000,000 or more must appoint an accredited service provider by 30 October 2026 and implement the system by 1 January 2027.
On 22 October 2026 we read the Ministry of Finance e-invoicing portal and the decisions it publishes, downloading each PDF and reading its text. The 30 October date is not the one in most guides, which still repeat 31 July. We did not read the penalty decision the ministry now lists, so the fines below carry a caveat. This is general information, not legal or tax advice.
| Business group | Appoint a provider by | Implement by |
|---|---|---|
| Revenue of AED 50,000,000 or more | 30 October 2026 | 1 January 2027 |
| Revenue below AED 50,000,000 | 31 March 2027 | 1 July 2027 |
| Government entities | 31 March 2027 | 1 October 2027 |
| Pilot and voluntary use | Open to any business | From 1 July 2026 |
UAE e-invoicing deadlines by business group
Ministerial Decision No. 244 of 2025 set the phases, and Ministerial Decision No. 66 of 2026 changed one line of them. The large-business appointment date moved from 31 July 2026 to 30 October 2026, and the 1 January 2027 implementation date stayed.
After the three phases finish, the decision says every person or government entity subject to the system must appoint a provider and implement it. The pilot programme began on 1 July 2026, and any business could also start voluntarily from that date.
Who has to use UAE e-invoicing
The Ministry of Finance defines an e-invoice as structured invoice data, exchanged electronically and reported to the Federal Tax Authority. It says PDFs, Word files, images, scans and emails are not e-invoices.
Revenue means gross income in the most recent accounting period, according to the financial statements. Business-to-consumer transactions are outside the system, and a business that deals only with consumers is outside it too, until the minister decides otherwise.

What changed on 1 October 2026
Ministerial Decision No. 197 of 2026 amends Decision No. 243 of 2025 and came into force on 1 October 2026. It sets a fourteen-business-day limit and a longer list of exclusions.
- Issue window: an e-invoice or credit note must be issued and transmitted through the system within 14 business days of the transaction.
- Same tax group: transactions between members of one tax group are excluded for 24 months from 1 January 2027.
- Airlines: international passenger transport with an electronic ticket, and ancillary services with an electronic miscellaneous document, are excluded. International goods transport on an airway bill is excluded for 24 months from the date the system takes effect.
- Finance: financial services that are exempt from VAT or zero-rated are excluded, as are government sovereign activities not in competition with the private sector.
- Records: e-invoices and their data must be kept for the period the Tax Procedures Law sets and be producible to the authority on request.
A business may still issue e-invoices voluntarily for excluded transactions, and in that case the penalty decisions do not apply to it.
Accredited providers and the pilot
The ministry’s October 2026 programme document counts 65 accredited service providers and 5 pre-approved ones, with 10 more in the pipeline and about 20 under review. It says exchange of e-invoices between businesses is now open and that businesses can onboard with a provider through EmaraTax.
The same document says the five-corner model is live for the pilot phase, and that participants will test invoice exchange, interoperability and compliance. It encourages every business to choose a provider and start the contract and onboarding steps now.
UAE e-invoicing penalties and which decision applies
Gulf News reported on 8 December 2025 the fines set by a Cabinet resolution, which the ministry’s portal still lists as Cabinet Decision No. 106 of 2025. They apply to entities required to use the system, and voluntary users are exempt until it becomes mandatory.
- Not implementing the system, or not appointing a provider on time: AED 5,000 per month.
- An e-invoice or credit note not issued or sent on time: AED 100 each, capped at AED 5,000 per month.
- Not telling the tax authority about a system malfunction: AED 1,000 per day.
- Delay in telling the provider about changes to registered data: AED 1,000 per day.
The October 2026 programme document marks Decision No. 106 of 2025 as repealed and lists Cabinet Decision No. 173 of 2026 instead. We could not find its text, so check these amounts against the current decision before relying on them.
Where the sources disagree
Two differences between the ministry’s own documents matter for any business planning its dates and its exposure to fines, so check which version you are reading.
- Appointment date: Decision 244 of 2025 and many guides give 31 July 2026 for large businesses, while Decision 66 of 2026 gives 30 October 2026.
- Penalty decision: the portal’s legislation list still names Decision 106 of 2025, while the October 2026 programme calls it repealed and names Decision 173 of 2026.
What we could not confirm
Several points stay open after our reading, because the decision copies carry blank issue dates and the newest penalty decision was not found.
- The text and fine amounts of Cabinet Decision No. 173 of 2026.
- The Official Gazette publication dates of Decisions 66 and 197 of 2026.
- Whether the 30 October 2026 date changes again.
- When business-to-consumer transactions will be brought in.
