UAE eInvoicing deadlines explained: who must appoint an ASP and go live, and when

Published 23 October 2026 · Updated 24 October 2026 · Official sources last reviewed 22 October 2026 · 13 min read

The United Arab Emirates is moving from paper and PDF invoices to a national electronic invoicing (eInvoicing) system, in which invoices are exchanged in a structured electronic format through accredited service providers (ASPs). For finance teams the most pressing questions are simple: which deadline applies to us, what exactly do we have to do by that date, and how much time is left? This guide answers those questions using only the official Ministry of Finance (MoF) and Federal Tax Authority (FTA) texts, and links to each of them so you can check the wording yourself.

It is written for finance managers, controllers, business owners and the advisers who support them. It does not decide whether your business is in scope; that depends on the detailed rules discussed below. If you only need the dates, see the key dates summary on our home page.

The short answer: three phases, two deadlines each

The rollout is set out in Ministerial Decision No. 244 of 2025 on the implementation of the eInvoicing system, as amended by Ministerial Decision No. 66 of 2026. Each phase has two milestones. The first is the date by which you must appoint an accredited service provider. The second, later date is when mandatory implementation begins, meaning eInvoicing must actually be live in your business. The table below shows the current dates.

UAE eInvoicing phases (Decision 244/2025 as amended by Decision 66/2026)
Category	Appoint an ASP by	Implementation by
Annual revenue AED 50 million or more	30 October 2026	1 January 2027
Annual revenue below AED 50 million	31 March 2027	1 July 2027
Government entities	31 March 2027	1 October 2027

The revenue-based phases apply to persons who are subject to the eInvoicing system. A revenue figure on its own does not tell you that you are subject; it only tells you which timetable applies if you are. The FTA repeated this qualification when it set out the same schedules in its 29 September 2026 announcement.

Phase one: revenue of AED 50 million or more

Dates

Persons subject to the system whose revenue is equal to or exceeds AED 50,000,000 must appoint an ASP by 30 October 2026 and implement eInvoicing by 1 January 2027. These dates come from Article One of Ministerial Decision 66/2026, which replaced Article 5(1)(a) of Decision 244/2025.

Why the earlier July date no longer applies

The original text of Decision 244/2025 set the ASP appointment deadline for this group at 31 July 2026. In May 2026 the Ministry of Finance announced targeted amendments that moved that deadline to 30 October 2026 while keeping the 1 January 2027 implementation date unchanged. If you see 31 July 2026 in older articles, presentations or vendor material, it is out of date. Decision 66/2026 changed only this first paragraph; it did not change the dates for the other two phases.

The AED 50 million boundary

A business with revenue of exactly AED 50,000,000 falls into the first phase, not the second. The MoF May 2026 announcement used the word “exceed”, which could be read as excluding the boundary figure, but the binding text of Decision 66/2026 says “equal to or exceeding”, and the FTA’s September 2026 announcement uses the same inclusive wording. Where a press release and the decision differ, rely on the decision.

Phase two: revenue below AED 50 million

Persons subject to the system with revenue below AED 50,000,000 must appoint an ASP by 31 March 2027 and implement eInvoicing by 1 July 2027, under Article 5(1)(b) of Decision 244/2025. This group has roughly three months between the appointment deadline and go-live. That is a short window for testing invoice data, connecting an accounting or ERP system and training staff, so appointing a provider well before the deadline is the safer plan.

Phase three: government entities

Article 5(1)(c) of Decision 244/2025 gives Government Entities their own timetable: appoint an ASP by 31 March 2027 and implement by 1 October 2027. The appointment deadline is the same as for smaller businesses, but the implementation date is three months later. This paragraph was not changed by Decision 66/2026. Private suppliers that sell to government bodies should not assume the government date applies to them; their own phase is set by their own revenue.

How “revenue” is measured

The official definition

Article 1 of Decision 244/2025 defines Revenue as gross income during the most recent Accounting Period, based on the financial statements the business is required to prepare or, where those are not available, other documentation acceptable to the FTA. In practice, most businesses will start from the revenue figure in their latest financial statements.

Where you may need professional advice

The definition does not, on its own, answer every situation. How revenue should be treated for groups of related entities, businesses with unusual accounting periods, or entities whose latest statements are not yet finalised are questions for a qualified UAE tax adviser. If your revenue sits close to AED 50 million, the difference between the two revenue phases is about five months for ASP appointment and six months for go-live, so it is worth confirming the figure early rather than assuming the later timetable.

What is excluded for now

Business-to-consumer (B2C) transactions

Article 5(2) of Decision 244/2025 states that B2C transactions, and persons engaged exclusively in B2C transactions, are not subject to the system until a future ministerial decision sets a date. A business that sells only to consumers is therefore outside the current timetable. A business that sells to both consumers and other businesses should not treat itself as excluded; the exclusion is about B2C transactions and persons engaged solely in them. Our guide to the B2C exclusion for B2C-only and mixed businesses explains how to read Article 5(2).

Transactions within a VAT Tax Group

Ministerial Decision 197/2026, in force from 1 October 2026, amended the exclusions in Decision 243/2025. Under the amended Article 4(1)(f), business transactions between members of the same VAT Tax Group are excluded transactions for 24 months starting 1 January 2027. The same decision made other changes, so read the full list of exclusions in the official text. Our guide to the Decision 197/2026 changes explains the Tax Group exclusion and the new record-keeping rules in more detail. To see which of the five decisions sets each rule and which original wording, such as the 31 July 2026 date, has been replaced, read our legislation map and amendment history. For short answers to the most common questions, with links to the detailed guides, see our UAE eInvoicing FAQ.

Why you still need to check Decision 243/2025

Decision 244/2025 sets the timetable, but scope and exclusions are dealt with in Ministerial Decision 243/2025 and its amendments. Whether a particular entity or transaction is subject is a separate analysis of those rules and of any later decisions. Revenue bands do not create exemptions, and this guide does not determine whether any specific business is in or out of scope. The MoF keeps the current list of legislation on its eInvoicing programme page.

Choosing a provider after Decision 168/2026

On 9 October 2026 the Ministry of Finance announced Ministerial Decision 168/2026 on the accreditation of eInvoicing service providers. It took effect from 1 October 2026 and repealed the earlier rules in Decision 64/2025 and its amendments, including Decision 56/2026. The new framework removes the former pre-approval stage and introduces direct accreditation.

This matters when you choose a provider. A label such as “pre-approved” from the earlier framework is not the same as accreditation under the current rules. Before you sign, ask the provider for evidence of its current accreditation and reconfirm it through official channels. Given how close the first-phase deadline is, also confirm the provider can onboard you within your timeframe.

A practical order of work

The steps below are an editorial planning sequence, not an official checklist. They reflect the dependencies most finance teams face when moving to structured electronic invoices.

Confirm whether you are subject to the system. Review Decision 243/2025 as amended, including the B2C and Tax Group exclusions, with your tax adviser if anything is unclear.
Fix your revenue figure and phase. Use the Article 1 definition and your latest financial statements, and record how you reached the answer.
Put the two dates in your plan. Work backwards from your implementation date and treat the ASP appointment date as a hard deadline.
Name an owner. eInvoicing touches finance, IT, sales and procurement; one accountable person keeps decisions moving.
Review your invoice data. Structured invoices depend on complete and consistent customer, supplier, product and tax data. Gaps found now are cheaper to fix than rejected invoices later.
Map your systems. List every system that creates or receives invoices, including manual and spreadsheet processes, and how each will connect to the provider.
Shortlist and appoint an accredited provider. Check current accreditation under Decision 168/2026 and agree a realistic onboarding timetable.
Test before go-live. Run sample invoices, credit notes and unusual cases end to end, and train the people who will handle exceptions.
Watch for changes. Dates and exclusions have already been amended more than once. Check the official MoF page regularly.

What to do now, by category

The dates are fixed by the decisions described above; what happens between them is up to each business. The notes below are an editorial summary of sensible preparation for each category, organised around the official appointment and implementation dates. They are not an official checklist. They do not describe extensions or grace periods, because the official texts we reviewed do not give us a verified basis for doing so. Penalties are set in a separate instrument, Cabinet Decision 106/2025: failing to implement the system, including failing to appoint an ASP within the ministerial timeline, carries AED 5,000 for each month of delay or part of a month, and failing to issue and transmit an Electronic Invoice or Electronic Credit Note on time carries AED 100 per document, up to AED 5,000 per calendar month. It does not apply to voluntary participants. We have not confirmed its exact entry-into-force date (the Official Gazette publication date) or how the FTA applies it in practice; see our Cabinet Decision 106/2025 penalties guide. Where a step depends on a specific rule, we link to the guide that explains that rule in detail.

Revenue of AED 50 million or more

This group has the least time. The ASP appointment date is 30 October 2026 and implementation follows on 1 January 2027, roughly two months later. When this guide was updated on 24 October 2026, the appointment date was less than a week away, so the priority is to make the appointment properly and then use every remaining week for onboarding and testing.

Before the appointment date: confirm that your chosen provider holds current accreditation under Decision 168/2026, keep a record of the evidence you relied on, and make sure the appointment is documented with a date and a named internal owner. If you have not yet chosen a provider, treat that decision as the most urgent item in your plan.
Straight after the appointment: agree an onboarding timetable with the provider that works back from 1 January 2027, and confirm which of your systems will send and receive documents through it, including any manual or spreadsheet processes.
In the weeks before go-live: correct the customer, supplier and item data that every structured invoice depends on, map your invoice fields to what the provider expects, and test ordinary invoices, credit notes and unusual cases from end to end.
With your trading partners: identify which customers and suppliers are in a different phase from you, and agree how invoices and credit notes will be exchanged with each of them while the phases overlap.

Our week-by-week roadmap for Revenue of AED 50 million and above lays these steps out against the calendar.

Revenue below AED 50 million

Persons subject to the system in this group must appoint an ASP by 31 March 2027 and implement by 1 July 2027. Because the appointment date is still months away, it is tempting to wait. A better use of the time is to finish the work that does not depend on a provider first, so that the short window between appointment and go-live can be spent on connection and testing.

Now: confirm your Revenue figure under the Article 1 definition and keep a note of how you reached it, especially if your figure is close to AED 50 million. Review, with an adviser if needed, whether your business and its transactions are within scope.
Over the coming months: tidy master data, list every system and spreadsheet that creates or receives invoices, and shortlist providers whose current accreditation you can verify.
By 31 March 2027: appoint a provider, leaving enough time before 1 July 2027 to connect systems, test documents and train staff. That window is only about three months.
Throughout: larger customers and suppliers whose implementation date is 1 January 2027 may ask about your plans before your own go-live. Agree with them how invoices will be exchanged in the meantime rather than assuming nothing changes until your own date.

Our month-by-month roadmap for businesses below AED 50 million turns these steps into a working plan.

Government Entities

Government Entities share the 31 March 2027 appointment date with the smaller revenue group but implement later, on 1 October 2027, which leaves about six months between the two milestones. Preparation follows the same pattern as for businesses: confirm scope, organise data and systems, appoint an accredited provider and test before go-live. Scope deserves particular care, because Article 4 of Decision 243/2025, as replaced by Decision 197/2026, excludes certain sovereign Government Entity transactions that do not compete with the private sector, so an entity needs to know which of its activities fall inside the system. Private businesses that sell to government bodies follow their own revenue phase, not this timetable. Our Government Entity timeline guide explains the Article 5(1)(c) phase in more detail.

Appointment date versus go-live date

Each phase has two dates, and they mean different things. The appointment date is the deadline for engaging an accredited service provider. Under Decision 243/2025, Issuers and Recipients meet their eInvoicing obligations through an ASP, so the appointment is what makes compliance possible at all. The implementation date is when the system becomes mandatory for the category: from then on, an Issuer is expected to issue and transmit Electronic Invoices and Electronic Credit Notes through the system, and a Recipient is expected to receive and process them through the system, as set out in Article 6.

An appointment on its own does not make a business ready. A signed agreement with a provider is the start of the technical work, not the end of it. The period between the two dates exists so that each business can connect its systems, align its data and prove that documents flow correctly before the obligations apply in practice. A business that appoints a provider on the last possible day still has to fit all of that work into whatever time remains before its implementation date.

What testing means in this window

In practical terms, testing means sending and receiving real-looking documents through the provider before they count. That includes ordinary invoices, credit notes for each kind of adjustment your business makes, documents with unusual values or many lines, and documents for customers or suppliers whose data is incomplete. Each test should be checked against the source record in your accounting or ERP system, so that you know the structured document says what the original transaction says. Failures found in testing can be fixed calmly; failures found after go-live affect real customers and suppliers. Our go-live testing checklist lists cases worth covering.

Why trading partners need to be confirmed

eInvoicing has two sides. Article 6 places obligations on both the Issuer and the Recipient, so an invoice only works if both parties are ready to send and receive it through the system. Customers and suppliers may be in different phases, may use different providers, and may hold master data about you that is out of date. Using the time after appointment to confirm identifiers, contact points and expected document flows with your main trading partners reduces the number of documents that are delayed or questioned once the obligations apply. Our trading partner onboarding guide sets out a practical approach.
