UAE E-Invoicing Timeline: Who Must Comply and When
Updated 2026-10-13 · by Brandew · اقرأ بالعربية
The UAE is introducing mandatory electronic invoicing in phases. Your start date depends mainly on your annual revenue, and every business in scope has two deadlines: one to appoint an accredited service provider (ASP), and a later one to go live.
The phased timeline at a glance
| Who | Appoint an ASP by | Go live by |
|---|---|---|
| Pilot participants (selected businesses that agree in writing) | - | From 1 July 2026 |
| Any business choosing to adopt voluntarily | - | From 1 July 2026 |
| Businesses with revenue of AED 50 million or more | 31 July 2026 | 1 January 2027 |
| Businesses with revenue below AED 50 million | 31 March 2027 | 1 July 2027 |
| Government entities (regardless of revenue) | 31 March 2027 | 1 October 2027 |
How revenue is measured
The guidelines define revenue as the gross income earned by a business during its most recent accounting period, based on its financial statements. Where financial statements are not available, other documentation acceptable to the Federal Tax Authority is used. If you are close to the AED 50 million line, confirm which phase applies with your tax adviser early.
Phase 1: large businesses (AED 50 million and above)
These businesses should already have appointed their ASP by 31 July 2026 and must issue and receive e-invoices from 1 January 2027. The remaining months are for integration and testing: connecting ERP, accounting, booking or order systems to the ASP, cleaning customer data and running test invoices end to end.
Phase 2: all other businesses (below AED 50 million)
Most small and medium-sized companies in Dubai and the wider UAE fall here. The ASP must be appointed by 31 March 2027 and e-invoicing must be live by 1 July 2027. Phase 1 companies will start sending you structured e-invoices from January 2027, so suppliers and buyers in this group benefit from preparing early.
Phase 3: government entities
Government entities appoint their ASP by 31 March 2027 and implement by 1 October 2027. Their sovereign activities are outside scope, but their other transactions with businesses are covered.
Pilot and voluntary adoption from 1 July 2026
A pilot with selected businesses started on 1 July 2026, and any business can join voluntarily from the same date. Early adoption gives time to fix data and system issues before the mandatory date applies.
What to do now, by phase
- AED 50 million or more: complete integration and testing with your ASP before 1 January 2027.
- Below AED 50 million: list every system that creates invoices, shortlist ASPs, and plan integration work before 31 March 2027.
- All businesses: collect buyers' Tax Registration Numbers and keep master data accurate; you will need them for e-invoice addressing.
