eInvoicing is not a VAT rule. It catches you even if you are not VAT-registered.

Who is in scope, in the law's own words

Article 3 of Ministerial Decision No. 243 of 2025 applies the Electronic Invoicing System to "any Person conducting Business in the State in respect of every Business Transaction", subject only to the exclusions in Article 4. There is no revenue floor in that sentence, no VAT registration condition, and no carve-out for freelancers or single-owner LLCs. The phased timetable in Ministerial Decision No. 244 of 2025 decides when the obligation reaches you; Article 3 has already decided whether.

Two more points from the same source that widen it further. A person without a place of residence in the UAE who is obliged to issue tax invoices under the VAT law must issue them as electronic invoices. And your customer's own status is irrelevant: the guidelines state that "a customer's Electronic Invoicing onboarding status or tax registration status does not affect the Electronic Invoicing obligations in respect of a Business Transaction". You cannot wait for the other side.

The transaction grid

Scope is decided by who is on each end of the transaction, not by what is being sold.

The B2C carve-out is bigger than it looks — and narrower than it sounds. Article 5(2) of MD 244 puts business-to-consumer transactions outside the system, and a person engaged exclusively in such transactions is not subject to the system at all, "until such time determined by a decision issued by the Minister". So a pure retail shop or a salon is, for now, out entirely. But a restaurant that also invoices corporate catering, or a clinic that also bills insurers and employers, is in scope for those transactions — the exemption is per-person only when the person does nothing else.

Your dates

Two details worth having straight. First, "Revenue" is defined, and it is not this year's run rate: MD 244 defines it as the gross income earned during the most recent Accounting Period, based on the financial statements you prepare under UAE law, or other documentation the FTA accepts if statements are not available. A business that crosses AED 50 million mid-2026 is still tested on the accounts it has closed.

Second, if you download the Ministry's own Electronic Invoicing Guidelines V1.1 (dated 1 June 2026), its phase table still prints 31 July 2026 as the Phase 1 ASP deadline. That figure was superseded by Ministerial Decision No. 66 of 2026, which replaced Article 5(1)(a) of MD 244 and moved it to 30 October 2026. The decision governs; the table has not caught up. It changes nothing for a business under AED 50 million, but it is the kind of discrepancy worth knowing about before you argue a date with anyone.

And there is a fourth line that is easy to miss. Article 5(1)(d) of MD 244 provides that once the three phases are complete, any person or government entity subject to the system must appoint an ASP and implement it. Businesses incorporated after 2027 do not inherit a grace period — they arrive into a system that is already fully switched on.

What is actually excluded

• Sovereign government activity — transactions by a government entity in a sovereign capacity that are not in competition with the private sector.
• Airline passenger services — international passenger transport where an electronic ticket is issued, and ancillary services to the same passenger covered by an Electronic Miscellaneous Document.
• Airline cargo, temporarily — international transport of goods under an airway bill, excluded for 24 months only, running from the date the system takes effect under Article 5 of MD 244.
• Financial services that are VAT-exempt under Article 42 of the VAT Executive Regulation, and those exempt services supplied to non-residents that qualify as zero-rated exports. Financial services that would be standard-rated for a resident customer stay in scope even when zero-rated as exports.

Note what is not on that list. Article 4(2) says the category of Excluded Persons "shall be determined by a decision issued by the Minister" — and no such decision has been issued. Until one is, there is no list of exempt businesses to check yourself against. The guidelines also close a door people assume is open: administrative exceptions the FTA grants in respect of tax invoices under the VAT Executive Regulation do not carry across to electronic invoices.

The step almost nobody has planned for: your TIN

Your identity inside the network is a Participant Identifier, and it is built on your Tax Identification Number — the first 10 digits of your 15-digit corporate tax TRN. That is fine if you are registered for corporate tax. The Ministry's mandatory-fields document then adds the sentence that catches everyone else: a person within the scope of eInvoicing but not required to register for corporate tax must register with the FTA to receive their TIN.

In other words, some businesses will have to make a tax registration they otherwise had no reason to make, purely to be addressable on the network. If you are in a tax group, note the second trap: your TIN is the first 10 digits of your own corporate tax TRN, not the group representative's.

One provider, and 100 invoices a year for free

Compliance runs through an Accredited Service Provider, and you appoint only one — the same ASP handles both what you send (receivables) and what you receive (payables). As of September 2026 the Ministry's published list carries 52 accredited providers, with a further 8 pre-approved and undergoing final assessment. It includes the international accounting suites, the Big Four, local audit firms and specialist tax-tech companies, so this is a competitive market rather than a queue.

The clause to put in your contract. Article 10(4) of Ministerial Decision No. 64 of 2025 requires every accredited provider to declare that it is "committed to providing per annum (100) hundred free eInvoice exchange and reporting services commencing from the date of the signature of the End-User agreement". The Ministry's own selection guide tells you to make sure it is written into your terms. For a consultancy or trading company issuing a handful of business invoices a month, that is the entire annual volume — the compliance cost can legitimately be close to zero, and any provider quoting you a per-invoice price from invoice one is quoting against their own accreditation declaration.

The rest of the Ministry's selection checklist is a genuinely useful buying script: how long they have been a Peppol service provider (not just how long the company has existed), whether the platform is their own product or a resold third-party one, whether support is in-house or subcontracted, whether it integrates with your existing accounting system, what security and ISO certifications they hold, what the SLA says about uptime, and whether the pricing is subscription or per transaction. Ask those before you ask the price.

What changes on the invoice itself

• A PDF is not an electronic invoice. The valid form is structured XML under the UAE's PINT-AE specification, exchanged through ASPs on a five-corner model: you, your ASP, the buyer's ASP, the buyer, and the FTA as the fifth corner receiving the tax data in parallel.
• Timing: 14 days. The invoice or credit note must be issued and transmitted through the system within 14 days of the Date of Business Transaction — defined as the earlier of the date the transaction occurred and the date payment was received. If you are VAT-registered, the VAT law's own timeline applies to you first.
• Credit notes are mandatory in four cases: the transaction is cancelled, the agreed consideration is reduced, the consideration is returned in whole or in part, or an administrative or numerical error has occurred.
• eInvoicing does not replace the tax invoice. Your obligation to issue a tax invoice survives — Article 65(5) of the VAT Decree-Law simply requires that it now take the form of an electronic invoice. And during the transition you may still need to produce an ordinary readable invoice for a buyer who is not yet onboarded, so that they can recover input tax and see what they owe.

Storage: "within the State" does not mean UAE servers

Article 11 of MD 243 says data must be stored "within the State", and that phrase has been read across the market as a data-residency mandate that would rule out foreign cloud accounting software. Guidelines V1.1 says otherwise, in terms. You meet Article 11 where the records are held in an electronic system that preserves their integrity, the storage infrastructure — "whether located inside or outside the UAE" — lets you produce them promptly on request, and the FTA can retrieve and reproduce them complete and readable. The Ministry states the policy intent directly: "within the State" is to be read as requiring accessibility and reproducibility for the FTA, "irrespective of the geographic location of the servers, databases, or cloud-based solutions used to store them".

The retention periods come from the Tax Procedures Executive Regulation: 5 years after the relevant tax period for a taxable person, 5 years from the end of the calendar year of creation for everyone else, and 7 years for real estate records — extended by a further 4 years during a dispute or audit, and by 1 year from a voluntary disclosure made in the fifth year.

Three situations with their own answer

• VAT groups get 24 months. Intra-group transactions are in scope and are not excluded merely for being intra-group — but Guidelines V1.1 grants a temporary grace period for business transactions between members of the same VAT group, for 24 months from 1 January 2027. It defers timing only; the obligation lands in full when it expires. The grace period, the per-member onboarding and the self-billing rules are set out here.
• Investment holding companies. A company whose revenue is purely passive and which conducts no business transactions is out of scope. The moment it recharges management or operating costs to a third party or a related party, those recharges are business transactions and it is in.
• Government tenders. Goods and services supplied to government entities — including through the federal procurement portal — are squarely in scope. If any part of your revenue is public-sector, treat your date as fixed.

The free rehearsal, and why it is worth taking

Voluntary implementation has been open since 1 July 2026, to any person regardless of revenue. Article 4(3) of MD 243 sets the terms honestly: opt in and the whole regime applies to you mandatorily — every technical requirement, every obligation — except the decisions on violations and administrative penalties. Cabinet Decision No. 106 of 2025 says the same thing from the other side, and the guidelines put a date on it: penalties apply only from the date you are required to implement on a mandatory basis.

That produces an unusually clean arrangement. Between now and 1 July 2027 a Phase 2 business can onboard, break things, misfile, and fix its master data with no penalty exposure at all. From 1 January 2027 your larger customers will be exchanging structured invoices whether or not you are ready, and the transitional friction lands on whoever is least prepared. The rehearsal is free; the opening night is not. See what the penalties actually are — one of them has no cap.

What to do before 31 March 2027

1. Decide whether you are in scope at all — do you invoice any business or government entity, or only consumers?
2. Fix your revenue figure from your last closed accounting period, and write down which phase that puts you in.
3. Check you have a TIN. If you are not registered for corporate tax, register with the FTA to obtain one.
4. Shortlist three accredited providers from the Ministry's list, run the selection questions above, and confirm the 100 free invoices per annum in writing.
5. Ask your accounting software vendor one question: are they an ASP themselves, do they integrate with one, or are you changing systems? Several names on the accredited list are ordinary accounting packages, which makes this a settings change rather than a migration.
6. Onboard voluntarily and run live invoices through the system while penalties still cannot apply to you.
