UAE e-invoicing now has fixed dates. Businesses with revenue of AED 50 million or more must appoint an Accredited Service Provider (ASP) by 30 October 2026 and issue and receive e-invoices through the Electronic Invoicing System from 1 January 2027. Businesses below AED 50 million follow on 1 July 2027 (ASP by 31 March 2027), and government entities on 1 October 2027. The framework is set by Ministerial Decisions No. 243 and No. 244 of 2025, amended by Ministerial Decision No. 66 of 2026. This guide puts every date in one table and shows which wave your business is in.
What the Electronic Invoicing System actually requires
The system replaces free-format invoicing for B2B and B2G transactions. From your go-live date you must issue and receive invoices as structured data, exchanged through an accredited service provider and reported to the Federal Tax Authority. Three points catch businesses out:
- An e-invoice is structured data, not a PDF. Unstructured formats — PDF, Word, images, scanned copies and emails — do not meet the requirement (Federal Tax Authority, UAE e-Invoicing guidance, tax.gov.ae).
- The UAE uses the Peppol five-corner model and the PINT AE invoice specification. Your accounting or ERP software must connect to an accredited service provider rather than print or email documents.
- All transactions in scope are covered, including those involving non-residents (Ministerial Decision No. 243 of 2025, published by the Ministry of Finance on 29 September 2025).
The deadlines, wave by wave
| Wave | Who | Appoint ASP by | Go live | Authority |
|---|---|---|---|---|
| Pilot and voluntary | Selected pilot participants; any person may adopt voluntarily | — | From 1 July 2026 | Ministerial Decision No. 244 of 2025, Art. 4 |
| Wave 1 | Revenue ≥ AED 50,000,000 | 30 October 2026 | 1 January 2027 | MD No. 244 of 2025, as amended by MD No. 66 of 2026 |
| Wave 2 | All other businesses in scope | 31 March 2027 | 1 July 2027 | MD No. 244 of 2025 |
| Government entities | Federal and local government bodies | 31 March 2027 | 1 October 2027 | MD No. 244 of 2025 |
| B2C-only businesses | Businesses transacting only with consumers | Excluded until further notice | — | MD No. 243 of 2025 |
The revenue test is measured for the most recent accounting period. A business sitting just under AED 50 million today should still plan its integration, because the Wave 2 clock runs on 31 March 2027.
What changed on 10 May 2026 — and what did not
Only one date moved. Ministerial Decision No. 66 of 2026 moved the Wave 1 ASP appointment deadline from 31 July 2026 to 30 October 2026. The 1 January 2027 go-live did not move, and the FTA reconfirmed both Wave 1 dates on 29 September 2026 at a joint meeting with accredited providers attended by more than 700 participants.
Also in force since 1 October 2026: the updated accreditation framework (Ministerial Decision No. 168 of 2026, announced 9 October 2026), under which a provider must pass assessment and testing before it is accredited. A signed contract with a provider that is not yet on the accredited list does not satisfy the deadline — verify the provider's status against the official list before you commit.
Penalties for missing the dates
| Violation | Administrative penalty |
|---|---|
| Failure to implement the system, including failure to appoint an ASP, within the specified timeline | AED 5,000 for each month or part of a month of delay |
| Failure to issue and send an e-invoice through the system on time | AED 100 per invoice, capped at AED 5,000 per calendar month |
| Failure to issue and send an e-credit note on time | AED 100 per credit note, capped at AED 5,000 per month |
| Failure to notify the FTA of a system failure (issuer or recipient) | AED 1,000 for each day or part of a day of delay |
Cabinet Decision No. 106 of 2025 applies to persons subject to the system — voluntary participants are excluded. A three-month implementation delay alone accumulates AED 15,000 before the system is even operational.
Which wave is your business in — the decision checklist
- Compute revenue for the most recent accounting period across all business activities.
- Revenue ≥ AED 50 million: your ASP must be appointed by 30 October 2026 and the system live by 1 January 2027. With the deadline days away, provider selection and integration testing are the two actions that matter now.
- Revenue below AED 50 million: appoint an ASP by 31 March 2027 and go live by 1 July 2027. Use the voluntary phase from 1 July 2026 if you want to test the integration early.
- Check accreditation, not marketing claims. A provider must be accredited under Ministerial Decision No. 168 of 2026 to provide e-invoicing services.
- Prepare invoice data. Every invoice must carry the structured fields the PINT AE specification requires — TRN details, line items, amounts and references — or validation fails.

What is the penalty for missing the e-invoicing deadline?
AED 5,000 for each month or part of a month of delay in implementing the system or appointing an ASP, under Cabinet Decision No. 106 of 2025. Separate penalties apply for late e-invoices (AED 100 each, capped AED 5,000 per month) and unreported system failures (AED 1,000 per day).

No. An e-invoice is structured invoice data issued and exchanged through the Electronic Invoicing System and reported to the FTA. PDF, Word, images and emails are not e-invoices.
Get the integration right the first time
E-invoicing lands on top of your existing bookkeeping and VAT workflow. If your books are not reconciled before go-live, the structured invoice data will inherit the errors. Finanshels prepares UAE businesses for e-invoicing — reconciled books, VAT-ready data and ASP integration — alongside choosing the right e-invoicing solution.
