Two dates apply to you, not one.
When you must have appointed a provider, and when you must actually be live. Missing the first is a monthly fine. Missing the second stops your invoices reaching customers.

The legislative sequence
- October 2024
The legal hook
Federal Decree-Law No. 16 of 2024 amended the tax legislation to introduce the Electronic Invoicing System and its reporting mechanism, leaving the technical detail to later decisions.
- March 2025
Providers before taxpayers
Ministerial Decision No. 64 of 2025 set the eligibility criteria and accreditation procedure for service providers. The state built the supply side first.
- 29 September 2025
Scope and dates
Ministerial Decisions 243 and 244 of 2025 defined who is in scope, what is excluded, what obligations attach, and the phased timetable.
- December 2025
Teeth
Cabinet Decision No. 106 of 2025 set the violations and administrative penalties, and expressly exempted voluntary adopters.
- 23 February 2026
The field specification
The Ministry published the Electronic Invoicing Guidelines, the mandatory field requirements, and guidance on selecting a provider.
- 14 May 2026
The appointment deadline moves
Ministerial Decision No. 66 of 2026 replaced a single paragraph of Decision 244: Phase 1 appointment moved from 31 July to 30 October 2026. The Ministry cited market readiness and business feedback seeking wider technical options and more competitive pricing. Nothing else changed.
- 1 June 2026
Guidelines v1.1
An updated version of the Guidelines superseded v1.0.
- 1 July 2026
System live, voluntarily
The pilot commenced and voluntary implementation opened to any business meeting the technical requirements, with no penalty exposure.
- 30 October 2026
Phase 1 appointment deadline
Businesses with revenue of AED 50 million or more must have appointed a provider. Late appointment accrues AED 5,000 for each month or part month.
- 1 January 2027
Phase 1 go-live
Unchanged. Issuing, transmitting, receiving and reporting through the system.
- 31 March 2027
Phase 2 and government appointment deadline
Businesses below AED 50 million and government entities must have appointed a provider.
- 1 July 2027
Phase 2 go-live
- 1 October 2027
Government entities go live
The last dated phase in Decision 244. Any remaining person or entity in scope must then appoint a provider and implement.
Three things that catch people out
The extension made the job harder, not easier
Under the original dates a Phase 1 business appointed by 31 July and had five months to integrate and test. Appointing on 30 October leaves nine weeks, including the December holidays and a year-end close, so the realistic working time is closer to six. Businesses that read May's announcement as breathing room spent the wrong slack.
Phase 2 businesses are affected from January 2027, not July
Your Phase 1 customers go live on 1 January. They will be sending you structured invoices and expecting structured handling six months before your own obligation starts. Accounts payable meets the new world first.
The threshold is gross income, not taxable turnover
Revenue is defined as gross income for the most recent accounting period per your financial statements. That can include items excluded from your VAT turnover. Businesses near AED 50 million should check the statutory definition against their actual statements rather than assuming the VAT figure carries across.
Find out where you actually stand
A fixed-scope readiness assessment: confirmation of which phase applies to you, a mandatory-field gap analysis run against your real invoice output, the edge cases in your transaction mix that will fail in testing, and a shortlist of accredited providers matched to your ERP and your data residency position.
You get a written report and a working session to walk through it. Two to three weeks, priced before we start.
We take no commission from any provider, so the shortlist reflects fit, not our margin.
