UAE eInvoicing roadmap for businesses with Revenue of AED 50 million and above: a week-by-week plan from the 30 October 2026 ASP deadline to 1 January 2027 go-live

Published 23 October 2026 · Official sources last reviewed 22 October 2026 · 12 min read

If your business is a person subject to the UAE eInvoicing system and its Revenue is AED 50 million or more, yours is the first timetable to arrive. You must appoint an accredited service provider (ASP) by 30 October 2026 and implement eInvoicing by 1 January 2027. Counted from the publication date of this guide, that is 7 days to the appointment date and 70 days to go-live. There is no longer room for a month-by-month plan, so this guide works in weeks: a final check before the appointment date, what to confirm if that date has already passed, and a week-by-week plan for November and December 2026.

The roadmap is an editorial planning aid, not an official schedule from the Ministry of Finance (MoF) or the Federal Tax Authority (FTA). The only fixed dates in it are the two set by law. The weekly steps are a suggested order of work that you should adapt to your own systems, volumes and advisers. We do not name or compare providers, and we do not estimate costs.

Your two dates and how little time sits between them

The dates come from Article 5(1)(a) of Ministerial Decision 244/2025, as replaced by Ministerial Decision 66/2026. The MoF summarised that amendment in its announcement of targeted amendments to the eInvoicing decisions.

Legal milestones for the category AED 50 million and above (Decision 244/2025, Article 5(1)(a), as replaced by Decision 66/2026)
Milestone	Date	Days from 23 October 2026
ASP appointment	30 October 2026	7
eInvoicing implementation	1 January 2027	70

The window between appointment and go-live is 63 days, or about 9 weeks, and it includes the year-end period when finance teams are already busy with closing work. That window has to hold provider onboarding, data mapping, exception flows, testing and training. The practical consequence is simple: anything that does not depend on the provider should already be done, and anything that does depend on the provider should start the week after appointment.

For the full picture of all three timetables, see the key dates on our home page and our guide to the UAE eInvoicing deadlines.

Confirm the category one last time: Revenue, Accounting Period and the inclusive boundary

Before you act on a deadline this close, make sure it is your deadline. The category depends on Revenue, a defined term. Article 1 of Decision 244/2025 defines Revenue as gross income during the most recent Accounting Period, based on the financial statements you are required to prepare or other documentation acceptable to the FTA. Accounting Period is also defined in Article 1; read it in the official text rather than relying on a summary.

The boundary is inclusive. Decision 66/2026 rewrote Article 5(1)(a) to cover persons subject to the system with Revenue equal to or exceeding AED 50,000,000. A business with Revenue of exactly AED 50,000,000 therefore belongs here, not in the later timetable. If your figure is close to the line, the cost of a wrong answer is asymmetric: treating yourself as the larger category when you are not leaves you early, while the reverse could leave you late.

Record before the appointment date

The financial statements and Accounting Period used, and the Revenue figure taken from them.
Who in finance confirmed the figure, and whether a tax adviser reviewed a figure close to the boundary.
Any open question about how Revenue is measured, so it can be revisited when official guidance answers it.

Our guide to the AED 50 million revenue threshold covers the definition and its open questions in depth, and the glossary explains the defined terms.

Confirm that you are subject to the system and which transactions are in scope

Revenue tells you which timetable applies only if you are a person subject to the system. Scope is set by Ministerial Decision 243/2025. Its Article 4 exclusions were replaced in full by Ministerial Decision 197/2026 with effect from 1 October 2026, which the MoF described in its announcement of the amended regulations. Any scope analysis prepared before October 2026 should be re-read against the replaced Article 4.

Transaction scope and exclusions. Decision 243/2025 applies to Business Transactions unless they are excluded. See our transaction scope guide and the guide to sector exclusions.
The B2C exclusion. Article 5(2) of Decision 244/2025 excludes B2C transactions and persons engaged exclusively in them until a further ministerial decision. A large business with both consumer and business sales still needs a plan for the business side. See the B2C exclusion guide.
Government Entities. Government Entities follow their own timetable rather than a revenue category; see the Government Entity timeline.

If you are unsure, run the free eInvoicing readiness check and take the result to your tax adviser.

The final week before 30 October 2026: direct accreditation and official channels

The rules on who may act as a provider changed shortly before this deadline. Ministerial Decision 168/2026, in force from 1 October 2026, replaced the earlier service-provider rules (Decision 64/2025 and its amendments, including Decision 56/2026). It removed the former pre-approval stage and introduced direct accreditation, so an earlier pre-approval label is not the same as accreditation under the current framework. Reconfirm a provider's current accreditation status through official channels before you appoint it.

That change matters most in the last week. Proposals, slide decks or web pages prepared earlier in 2026 may describe a provider as “pre-approved”. Under the current framework that label alone does not show that the provider is accredited. Before you sign, check the provider's status through official channels, using the MoF announcement on Decision 168/2026 and the MoF eInvoicing programme page as starting points, and keep a dated record of what you checked.

Final-week checklist

Category and scope conclusions signed off by the project owner, with adviser input recorded where it was needed.
Provider's current accreditation confirmed through an official channel, with the date and the source noted.
Contract and onboarding terms reviewed by your own legal and procurement functions.
An onboarding and testing timetable agreed with the provider that ends before 1 January 2027.
Evidence of the appointment and its date filed where you can retrieve it later.

Our guide to choosing and appointing an ASP under Decision 168/2026 sets out the selection criteria in more detail.

If the appointment date has passed, or you have already appointed

This guide will still be read after 30 October 2026. Two situations need different checks.

You appointed on time

Confirm the record of the appointment is complete: date, provider, the accreditation check you made and who approved it.
Move directly to the weekly plan below. Every week of the 63-day window counts.

You did not appoint by the date

Do not assume a grace period. We have not identified an official extension of the 30 October 2026 date for this category in the texts we reviewed.
Know the penalty that is written down. Row 1 of the table annexed to Cabinet Decision 106/2025 covers failing to implement the system, including failing to appoint an ASP within the ministerial timeline: AED 5,000 for each month of delay or part of a month. We have not confirmed how the FTA counts the first month; see our Cabinet Decision 106/2025 penalties guide.
Record why the date was missed and what has been done since, appoint an accredited provider as soon as you can, and take advice from a qualified UAE tax adviser on your position.
Keep the go-live date in view: 1 January 2027 has not moved because an appointment was late.

Our guide to missing the 30 October 2026 ASP deadline covers these checks in more depth, including what remains unconfirmed and an editorial recovery order.

November and December 2026: a week-by-week plan to go-live

The weeks below assume an appointment made by 30 October 2026. Dates are calendar weeks; adjust them for your own working days and holidays.

Weeks 1 and 2 (2 to 15 November): onboarding and data

Hold a kickoff with the provider and confirm contacts, environments and the agreed testing timetable.
Hand over your invoice-route inventory: every system, billing tool, branch and spreadsheet that can create an invoice or credit note.
Extract counterparty master data and fix duplicates, missing values and conflicting records, starting with your highest-volume customers and suppliers.
Flag counterparties whose status affects scope, such as Government Entities, members of your VAT Tax Group and consumers.

Weeks 3 and 4 (16 to 29 November): systems and mapping

Map your invoice data against the requirements your provider and the current official specifications set. This site does not list field-level requirements.
Decide, system by system, how invoices will reach the provider, and who owns each integration.
Identify invoice details that exist only in PDFs, free text or attachments and decide how they will become structured data.

Weeks 5 and 6 (30 November to 13 December): credit notes and exception flows

Corrections, not ordinary invoices, are where projects usually stall. Article 6 of Decision 243/2025 sets out the cases in which a credit note is required: cancellation, a reduction of the consideration, a return of consideration, and administrative or numerical errors. For Issuers that are VAT Registrants, Article 6(4) points to the VAT Law timeline; Article 6(5), as replaced by Decision 197/2026, sets fourteen Business Days from the Date of Business Transaction, subject to Article 6(4).

Document one flow for each of the four credit note cases, with an owner and the time limit that applies to you.
Document how rejected or failed submissions are corrected and resubmitted.

See our guide to Issuer and Recipient obligations under Article 6.

Weeks 7 and 8 (14 to 27 December): scenario tests

Test normal invoices on each route, counterparty data errors, rejection and resubmission, each credit note case and recovery after an outage.
Record expected and actual results for every scenario, and give each defect a named owner.

The go-live testing checklist lists scenarios and the evidence worth keeping.

Week 9 (28 to 31 December): the go-live decision

Close or formally accept the remaining defects, with owners and dates.
Brief the staff who issue and process invoices, and tell key customers and suppliers what changes from 1 January 2027.
Record a go-live decision, who made it and the fallback steps if a route fails in the first days.

Our readiness project plan describes the underlying workstreams if you need to set them up from scratch.

The Tax Group exclusion that starts on the same day

1 January 2027 is also the start date of a temporary exclusion. Ministerial Decision 197/2026, which amended Decision 243/2025 with effect from 1 October 2026, treats Business Transactions between members of the same VAT Tax Group as Excluded Transactions for 24 months starting 1 January 2027 (amended Article 4(1)(f)). Check the full list of exclusions in the official text.

For a large business that is a member of a VAT Tax Group, this affects the plan in three ways. First, transactions between group members can be separated from the go-live scope, which may reduce the routes to test now; it does not remove sales to customers outside the group. Second, your systems need a reliable way to tell intra-group transactions from external ones, so group membership belongs in the master-data work of weeks 1 and 2. Third, the exclusion lasts 24 months, so the intra-group routes are a later project, not a cancelled one. Our guide to Decision 197/2026 explains the change.

How this timetable compares with the other two categories

All three timetables (Decision 244/2025, Article 5(1), with Article 5(1)(a) as replaced by Decision 66/2026)
Category	Appoint an ASP by	Implement by	Basis
Annual revenue AED 50 million or more	30 October 2026	1 January 2027	Including exactly AED 50,000,000. Decision 244/2025, Article 5(1)(a), as amended by Decision 66/2026.
Annual revenue below AED 50 million	31 March 2027	1 July 2027	Decision 244/2025, Article 5(1)(b).
Government entities	31 March 2027	1 October 2027	Decision 244/2025, Article 5(1)(c), which applies to Government Entities.

Businesses below AED 50 million appoint by 31 March 2027 and implement by 1 July 2027. If a subsidiary or related business falls in that category, our month-by-month roadmap for businesses below AED 50 million covers its plan.
Government Entities appoint by 31 March 2027 and implement by 1 October 2027. If many of your customers are Government Entities, they will join the system after you do.
Your category is the only one with both dates in 2026 and early 2027, and the only one with a window of about 9 weeks.

What this roadmap cannot confirm

We do not guess at questions the official texts we reviewed do not answer. Check current official texts and ask a qualified UAE tax adviser.

Penalties and extensions. The penalty amounts are set in Cabinet Decision 106/2025, which we read in the official English text on 24 October 2026 (see our penalties guide). We have not confirmed its exact entry-into-force date, how the FTA applies it in practice, or any extension for this category.
Category changes. We have not identified a rule on moving between categories if Revenue changes.
Group aggregation. Whether Revenue is measured per entity or combined across related entities is not settled in the material we reviewed.
Technical specifications. Field-level data requirements and any mandatory test procedures are not covered here.
Costs. We do not publish cost estimates.

Official updates appear on the MoF eInvoicing programme page and in FTA news, such as the joint awareness meeting for accredited service providers and persons subject to the eInvoicing system. Our legislation map shows which decision answers which question.

Frequently asked questions

Is this weekly plan an official schedule?

No. Only 30 October 2026 and 1 January 2027 are set by law. The weeks are an editorial suggestion.

Our Revenue is exactly AED 50 million. Which dates apply?

These ones. Article 5(1)(a), as replaced by Decision 66/2026, covers Revenue equal to or exceeding AED 50,000,000.

Our proposal says the provider is pre-approved. Is that enough?

Not on its own. Decision 168/2026 removed the pre-approval stage and introduced direct accreditation. Confirm current accreditation through official channels before you appoint.

We missed 30 October 2026. Is there an extension?

We have not found one in the official texts we reviewed. Cabinet Decision 106/2025 sets AED 5,000 for each month or part of a month of delay in implementing the system, including late ASP appointment; see our penalties guide. Appoint as soon as you can, record what happened and take professional advice.

Does the Tax Group exclusion delay our go-live?

No. The timetable in Decision 244/2025 is unchanged. The exclusion covers only transactions between members of the same VAT Tax Group, for 24 months from 1 January 2027.
