The UAE's mandatory e-invoicing system is close. Businesses with revenue of AED 50 million or more must appoint an Accredited Service Provider (ASP) by 30 October 2026 and be issuing e-invoices from 1 January 2027. At the same time, the Ministry of Finance has eased some of the rules, most importantly for transactions inside a VAT tax group.
The timetable
| Group | Appoint an ASP by | Implement e-invoicing by |
|---|---|---|
| Revenue of AED 50 million or more | 30 October 2026 | 1 January 2027 |
| Revenue below AED 50 million | 31 March 2027 | 1 July 2027 |
The scope and timetable come from Ministerial Decisions No. 243 and 244 of 2025. Ministerial Decision No. 66 of 2026 moved the ASP appointment date for the larger group from 31 July 2026 to 30 October 2026, without changing the 1 January 2027 go-live date. The Federal Tax Authority (FTA) repeated both dates at its meeting with ASPs and businesses on 29 September 2026.
What changed in October 2026: Ministerial Decision No. 197 of 2026
Ministerial Decision No. 197 of 2026 amends Ministerial Decision No. 243 of 2025 and took effect on 1 October 2026. It makes three changes:
- Tax groups get 24 months. Business transactions between members of the same tax group are treated as excluded transactions for 24 months from 1 January 2027, so intra-group invoices need not pass through the e-invoicing system during that period.
- Data can be stored outside the UAE. Businesses must keep all e-invoices, e-credit notes and the related data for the period required by the Tax Procedures Law and be able to provide them to the FTA on request — but the earlier requirement to store the data in the UAE has been removed.
- No "system failure" notifications. The provisions on system failure, including the duty to notify the FTA within two business days, have been repealed.
What to do before 30 October
- Confirm which revenue group you fall into, and the date that applies to you
- Shortlist and contract an Accredited Service Provider from the Ministry of Finance's list
- Plan the integration of your ERP or billing system with the ASP
- Complete the required steps on the FTA's EmaraTax platform once you have contracted the ASP
- Clean customer and supplier master data, especially Tax Registration Numbers
- If you are in a VAT tax group, map intra-group flows — they are excluded until the end of 2028, but external sales are not
- Update your record-retention policy for e-invoice data, wherever it is stored
The FTA has said that failing to meet the implementation requirements may lead to administrative penalties. Leaving the ASP decision to the last week risks a rushed integration before 1 January 2027.
