Your VAT group has 24 extra months. Your self-billing arrangement does not.
Two arrangements that most finance teams treat as internal plumbing — invoicing between group companies, and letting a large customer raise the invoice for you — behave very differently under the UAE eInvoicing system. Intra-group transactions are squarely in scope and then handed a temporary grace period of twenty-four months from 1 January 2027. Self-billing gets no concession at all: it survives, but only if the buyer is already live on the system, and the paperwork conditions that existed on paper survive with it.
Intra-group invoices are in scope. The Ministry says so before it gives you the grace period.
The first thing chapter 6.3.2 of Guidelines V1.1 does is close the argument. In accordance with Ministerial Decision No. 243 of 2025, it says, Business Transactions carried out between members of the same VAT group fall within scope and are not excluded solely by reason of being intra-group. Nothing in Article 4 of MD 243 — the exclusions article, which covers sovereign government activity, airline tickets and airway bills, and VAT-exempt or zero-rated financial services — mentions group companies. Nothing in MD 244, the implementation decision, addresses intra-group transactions either.
That matters because a VAT group files one return. Inside the group, supplies between members are disregarded for VAT. It is an easy step from there to assuming that the invoices are disregarded too, and many groups do not raise real invoices at all — they post intercompany charges through a shared ledger and settle on a schedule. The eInvoicing system is not a VAT return. It is a document-exchange obligation attached to a Business Transaction, and an intercompany recharge is one.
The grace period: 24 months, starting 1 January 2027
The Ministry and the FTA acknowledge the problem in plain terms — intra-group transactions involve high volumes, complex internal pricing and settlement arrangements, and centralised or automated intercompany charging, so bringing them into a structured exchange needs more time. The concession that follows is specific:
"To support implementation readiness for VAT groups, a temporary grace period will be provided in respect of intra-group transactions. The grace period will apply to Business Transactions carried out between members of the same VAT group for a period of twenty-four (24) months commencing on 01 January 2027. During this period, the electronic invoicing obligations under MD No. 243 of 2025 will not be required to be implemented in respect of Business Transactions carried out between members of the same VAT group." — Guidelines V1.1, ch. 6.3.2.1
Three consequences are worth spelling out, because the guidelines state each of them and each is routinely misread.
- The window runs from a fixed date, not from your phase date. It commences on 1 January 2027 — which is the go-live date for businesses at or above AED 50 million in revenue. A group member below that threshold goes live on 1 July 2027, six months into a window that still closes at the same point. The grace period is not twenty-four months for you; it is twenty-four months from 1 January 2027, and on the face of the text that puts the end of it at 31 December 2028.
- It affects timing only. The guidelines say so directly: the grace period "does not remove intra-group transactions from the scope of the Electronic Invoicing System and does not affect the application of Electronic Invoicing obligations to other Business Transactions carried out by the Person." Your sales to third parties are untouched. You are onboarded, you are issuing, you are reporting — you simply are not required to do it for the leg between two members of your own group.
- On expiry it applies in full, by phase. "Upon expiry of the grace period, the requirements of the Electronic Invoicing System will apply in full to Business Transactions carried out between members of the same VAT group, in accordance with the applicable mandatory implementation phase." There is no second transition and no tapering.
The planning implication is the opposite of the obvious one. A group whose external invoicing goes live on 1 January 2027 will have run the system for two full years before it has to point it at itself — by which time the intercompany data model is either fixed or two years more entangled. The grace period is time to rebuild intercompany charging, not time to ignore it.
Every member onboards separately, with its own TIN
A VAT group has one TRN for VAT purposes, held by the representative member. eInvoicing does not work that way, and the guidelines flag it twice — once in the summary at chapter 2 and once as a note in the onboarding steps at chapter 13.2.
| Question | What the guidelines say |
|---|---|
| Who onboards? | Each member of a Tax Group needs to be onboarded for Electronic Invoicing. Not the group, not the representative — each member. |
| Which identifier? | Each member has its own TIN, used to generate its individual Peppol participant identifier. |
| Where does the TIN come from? | The TIN is the first 10 digits of the TRN. "Even if you are part of a Tax Group, your TIN is the first 10 digits of your own TRN and not the first 10 digits of the Tax Group representative's TRN." |
| Must members share a provider? | No. "Each of the group members may onboard with a different ASP." |
| What if a member has no TRN of its own? | A person in scope of eInvoicing who is not required to register for any tax type must register with the FTA to obtain a TIN. There is no route to being in scope without an identifier. |
The mirror-image trap. Group structures change, and the identifier follows the change. The guidelines list joining or leaving a Tax Group among the changes in circumstances that require the participant's registration data to be updated — alongside registering for VAT and deregistering from a tax type. A member that leaves a group does not inherit a new identity for eInvoicing purposes, but the registration data behind the participant identifier has to be corrected, and that correction is the participant's job, not the provider's.
Self-billing: allowed, narrower than it looks, and dependent on your customer's phase
Self-billing is the arrangement where the buyer raises the document on the supplier's behalf — common where a large buyer's system is the authoritative record of what was delivered, as in recruitment, logistics, media buying and much of construction subcontracting. Article 9 of MD 243 keeps it:
"The Recipient may issue an Electronic Invoice or an Electronic Credit Note on behalf of the Issuer in respect of a supply of goods or services provided both the Recipient and Issuer are Registrants, in accordance with the conditions prescribed in the VAT Executive Regulation or as otherwise determined by the Minister." — MD No. 243 of 2025, Art. 9
Chapter 10.3 of the guidelines then attaches three practical limits.
- The buyer must be on the Electronic Invoicing System. Self-billing of electronic tax invoices "will require the buyer to be on the Electronic Invoicing System" — the document has to be issued and transmitted through the network, and only a participant can do that.
- There is no commercial self-billing. Self-billing applies for VAT purposes only, under the conditions in the VAT Decree-Law, and is not available for suppliers who are not registered for VAT. The guidelines conclude: "there is no option for self-billing of Commercial Invoices." If you are below the VAT registration threshold but in scope of eInvoicing — which is the normal position for a small UAE business — a customer cannot self-bill you.
- Going live catches your self-billed supplies too. Once a supplier is in scope for mandatory eInvoicing, "this will extend to all Business Transactions, including those that are made under a self-billing arrangement."
The last point creates the timing problem the guidelines tell you to go and check: your obligation is measured against your phase date, but the document under a self-billing arrangement is issued by your customer, against theirs. The guidelines are explicit — "it is therefore important to check any self-billing arrangements with customers to ensure that the buyer is able to issue self-billed Electronic Invoices as the buyer may not be in scope for mandatory implementation at that point in time."
Which way round does this actually bite? A supplier at AED 50 million or more goes live on 1 January 2027; a buyer below that threshold goes live on 1 July 2027. In that six-month gap the supplier is required to have an electronic invoice for the supply and the buyer is not yet able to produce one. The practical answers are to suspend the self-billing arrangement for that period and have the supplier issue, or to have the buyer onboard voluntarily — the voluntary route has been open since 1 July 2026, and under Article 4(3) of MD 243 a voluntary participant takes on the full obligations of the system but not the penalty decisions. Voluntary onboarding to close a self-billing gap is therefore a low-risk move for the buyer and a compliance necessity for the supplier.
What the electronic form does not switch off
The move to XML disapplies a good deal of the paper-era rulebook, and it is tempting to assume the self-billing formalities went with it. They did not, and the reason is visible in the drafting.
Article 59(16) of the VAT Executive Regulation says that where a registrant must issue a tax invoice as an Electronic Invoice — or does so voluntarily — Clauses 2, 3, 5, 7, 8 and 15 of Article 59 do not apply. Clause 9 is the self-billing clause. It is not on the list. Article 60(8) does the same job for credit notes: it disapplies paragraph (e) of Clause 1 and Clauses 2 and 3, and leaves Clause 4, the self-billing clause for credit notes, standing.
| Condition | Tax invoice — Art. 59(9) | Tax credit note — Art. 60(4) |
|---|---|---|
| Recipient must be a Registrant | Yes | Yes |
| Agreement that the supplier will not issue | Yes — in writing | Yes |
| Document carries the full Clause 1 particulars | Yes | Yes |
| Prescribed wording on the face of the document | "Tax Invoice raised by buyer" | "Tax Credit Note created by buyer" |
| Effect on anything the supplier issues for the same supply | Deemed not to be a Tax Invoice — Art. 59(10) | Deemed not to be a Tax Credit Note — Art. 60(5) |
Two of those rows do real work. The written agreement is a condition of the document being treated as the supplier's, not a best practice — a self-billing arrangement running on a purchase-order clause and years of habit is worth putting on paper before the exchange becomes machine-readable. And Article 59(10) means a supplier who "also raises one for the file" has not created a backup: that invoice is deemed not to be a tax invoice at all, so it supports nothing, while the duplicate document sits in the FTA's records.
The guidelines add the general requirement that a self-billed electronic tax invoice must fulfil the same criteria as any tax invoice under the VAT Decree-Law and the VAT Executive Regulation. The field-level requirements are the same ones.
Self-billing is not agency, and agency does not move the obligation
The two arrangements are separate articles of MD 243 and they answer different questions. Article 8 allows an agent acting on behalf of a principal to issue and transmit the electronic invoice or credit note through the system on the principal's behalf. Article 9 allows the buyer to do it. Agency runs on the supplier's side of the transaction; self-billing crosses to the other side.
The distinction matters most when something goes wrong, because the guidelines state the allocation of responsibility twice in the scenarios table and both times it lands in the same place. For disclosed agents: "the responsibility to issue an Electronic Invoice remains with the supplier even if an agent issues one on its behalf." For e-commerce: "the responsibility to issue an Electronic Invoice remains with the supplier even if the e-commerce platform issues one on its behalf." Delegating the mechanics does not delegate the duty — the same principle the guidelines apply to storage delegated to a provider.
Note also what the scenarios table excludes: agent billing "does not apply for undisclosed agents." And the Executive Regulation attaches its own record-keeping condition to agent-issued documents — under Articles 59(11) and 60(6) the agent must retain records sufficient to determine the name, address and TRN of the principal supplier, and the principal must retain records sufficient to determine the same details for the agent. Both sides keep the file.
A passive holding company is out — until it recharges something
One structure sitting close to the group question is worth reading alongside it. Chapter 6.3.1 addresses investment holding companies: where a company's revenue is solely passive income and it has no Business Transactions, it is not in scope. But the guidelines immediately describe the ordinary exception — a recharge of operational costs, such as management costs, to third parties or related parties is a Business Transaction. In that case the holding company "would have an obligation to register for Electronic Invoicing and issue Electronic Invoices for any Business Transactions in line with the phased implementation plan."
Most holding companies in a UAE group structure recharge something. The test is not whether the entity trades; it is whether a single invoice leaves it.
Frequently asked questions
Do transactions between VAT group members need electronic invoices in the UAE?
Eventually, yes. Chapter 6.3.2 of the UAE Electronic Invoicing Guidelines V1.1 states that business transactions between members of the same VAT group fall within scope of the system and are not excluded solely because they are intra-group. However, a temporary grace period applies to intra-group transactions for 24 months commencing 1 January 2027, during which the eInvoicing obligations under Ministerial Decision No. 243 of 2025 do not have to be implemented for those transactions.
When does the UAE VAT group eInvoicing grace period end?
The guidelines describe a period of 24 months commencing on 1 January 2027, which on the face of the text ends on 31 December 2028. The start date is fixed and does not shift with your own mandatory implementation phase — a group member that goes live on 1 July 2027 still sees the window close at the same point. Upon expiry, the requirements apply in full to intra-group transactions in accordance with the applicable mandatory implementation phase.
Does the grace period mean intra-group transactions are outside eInvoicing?
No. The guidelines state that the grace period affects the timing of compliance only. It does not remove intra-group transactions from the scope of the Electronic Invoicing System, and it does not affect the application of eInvoicing obligations to the other business transactions carried out by the same person — sales to third parties are unaffected throughout.
Does each VAT group member need its own eInvoicing onboarding?
Yes. Chapter 13.2 of the guidelines states that each member of a Tax Group needs to be onboarded for Electronic Invoicing, each member will have its own TIN used to generate its individual Peppol participant identifier, and members may onboard with different accredited service providers.
What TIN does a VAT group member use for UAE eInvoicing?
Its own. The TIN is the first 10 digits of the TRN, and the guidelines state expressly that even if you are part of a Tax Group, your TIN is the first 10 digits of your own TRN and not the first 10 digits of the Tax Group representative's TRN. A person in scope who is not required to register for any tax type must register with the FTA to obtain a TIN.
Is self-billing still allowed under UAE eInvoicing?
Yes, for VAT documents. Article 9 of Ministerial Decision No. 243 of 2025 permits the recipient to issue an electronic invoice or electronic credit note on behalf of the issuer where both the recipient and the issuer are registrants, in accordance with the conditions in the VAT Executive Regulation. The guidelines add that the buyer must be on the Electronic Invoicing System to do so.
Can a buyer self-bill a supplier who is not registered for VAT?
No. Chapter 10.3 of the guidelines states that self-billing arrangements apply for VAT purposes only, under the conditions in the VAT Decree-Law, and are not available for suppliers who are not registered for VAT — and that there is consequently no option for self-billing of Commercial Invoices. A business below the VAT registration threshold can still be in scope of eInvoicing, but it cannot be self-billed.
What happens if my customer self-bills me but is not yet live on eInvoicing?
The guidelines tell suppliers to check exactly this. Once a supplier is in scope for mandatory eInvoicing the obligation extends to all business transactions, including those made under a self-billing arrangement — but the buyer may not yet be in scope at that point. The practical options are to suspend the self-billing arrangement so the supplier issues, or for the buyer to onboard voluntarily; voluntary onboarding has been open since 1 July 2026 and, under Article 4(3) of MD 243, brings the full obligations of the system but not the penalty decisions.
Does a self-billed electronic invoice still need the words "Tax Invoice raised by buyer"?
On the text as it stands, yes. Article 59(16) of the VAT Executive Regulation disapplies Clauses 2, 3, 5, 7, 8 and 15 of Article 59 for electronic invoices — Clause 9, which contains the self-billing conditions, is not among them. Those conditions are that the recipient is a registrant, that the supplier and recipient agree in writing that the supplier will not issue a tax invoice, that the document contains the Clause 1 particulars, and that the words "Tax Invoice raised by buyer" are clearly displayed. The equivalent for credit notes is Article 60(4), left standing by Article 60(8), with the words "Tax Credit Note created by buyer".
What happens if the supplier also issues an invoice for a self-billed supply?
It is not a tax invoice. Article 59(10) of the VAT Executive Regulation provides that where a tax invoice is issued by the recipient under Clause 9, any invoice issued by the supplier in respect of that supply is deemed not to be a tax invoice. Article 60(5) does the same for credit notes. A duplicate raised "for the file" supports nothing and leaves a second document in the record.
Is an agent issuing invoices the same as self-billing?
No. Article 8 of Ministerial Decision No. 243 of 2025 covers an agent issuing and transmitting on behalf of a principal; Article 9 covers the buyer issuing on the supplier's behalf. The guidelines state that the responsibility to issue an electronic invoice remains with the supplier even where an agent or an e-commerce platform issues one on its behalf, and that the agent-billing scenario does not apply to undisclosed agents.
Does eInvoicing apply to a holding company?
Not if its revenue is solely passive income and it has no business transactions. But chapter 6.3.1 of the guidelines notes that recharges of operational costs such as management costs, to third parties or related parties, do constitute business transactions — in which case the holding company must register for eInvoicing and issue electronic invoices for them in line with the phased implementation plan.

Verified 17 September 2026 against the Ministry of Finance's and the Federal Tax Authority's published PDFs, re-downloaded on the date of verification. The grace period is quoted from the guidelines as published; the end date of 31 December 2028 is arithmetic on the words "twenty-four (24) months commencing on 01 January 2027" and has not been stated as a date by the Ministry. The observation that Article 59(16) leaves Clause 9 in force — so the written agreement and the "Tax Invoice raised by buyer" wording continue to apply to self-billed electronic invoices — is our reading of the two provisions set side by side; both are quoted above.
