UAE e-Invoicing Requirements: What a Business Must Have in Place

The obligation is drawn by activity, not by tax registration. 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 and no VAT condition: a person under the VAT registration threshold, or registered for corporate tax only, is still in scope.

Revenue does not decide whether you are in scope. It decides when. Article 5(1) of Ministerial Decision No. 244 of 2025 splits the population at AED 50,000,000 of revenue, which Article 1 of that decision defines as gross income for the most recent accounting period per your financial statements — not a fixed calendar year. A person in scope who is not required to register for any tax must still register with the Federal Tax Authority to obtain a Tax Identification Number, because the TIN is what identifies you on the network.

This is the part that turns a policy into a systems project. An electronic invoice is not a PDF with a logo on it — it is an XML document that must validate against the UAE's Peppol specification, PINT AE, whose UAE-specific requirements sit in the Data Dictionary referred to in Article 7(4) of Ministerial Decision No. 64 of 2025. Article 7 of Ministerial Decision No. 243 of 2025 delegates the field list to the Ministry, which published it on 23 February 2026 as UAE Electronic Invoice mandatory fields, version 1.0.

There are two field sets. An electronic tax invoice — what a VAT registrant issues for a taxable supply — carries 51 mandatory fields. A commercial electronic invoice — used where the VAT Decree-Law does not require a tax invoice, for example exempt or out-of-scope supplies, or supplies by a person not registered for VAT — carries 49. The lists differ in three places only: the tax invoice takes the buyer's tax identifier and tax scheme code where the commercial invoice takes the buyer's legal registration identifier and its type, and the tax invoice adds two line-level fields, the VAT line amount in AED and the invoice line amount in AED.

Article 4 of Ministerial Decision No. 243 of 2025 lists the excluded transactions, and Article 5(2) of Ministerial Decision No. 244 of 2025 adds the business-to-consumer carve-out. The exclusions are narrow and specific:

• Sovereign activity. Business transactions conducted by a government entity in a sovereign capacity and not in competition with the private sector.
• Airline passenger services. International passenger transport supplied by an airline where an electronic ticket is issued, plus ancillary services where an electronic miscellaneous document is issued.
• Airline goods transport, temporarily. International transport of goods by an airline against an airway bill — but only for 24 months from the date the system becomes effective.
• Exempt financial services. Financial services exempt from VAT or zero-rated under Article 42 of the VAT Executive Regulation. The Guidelines add that standard-rated financial services are not excluded even where they qualify as zero-rated exports under Article 31.
• Business-to-consumer transactions, and a person engaged exclusively in them, until a further decision by the Minister.

What is not excluded catches people out. Free zone companies are in scope — the free trade zone flag exists precisely because those invoices travel the network. Intra-group transactions between members of the same VAT group are in scope, although the Guidelines grant a temporary 24-month grace period for them starting 1 January 2027. An investment holding company earning only passive income has no business transactions and is out of scope, but the moment it recharges management costs to a related party, it has one. A person with no place of residence in the UAE who is obliged to issue UAE tax invoices must issue them electronically.

You cannot connect to the Federal Tax Authority yourself. Article 6(7) of Ministerial Decision No. 243 of 2025 requires the issuer and the recipient to discharge their exchange and reporting obligations through the appointment of an Accredited Service Provider, and Article 3(1) of Ministerial Decision No. 64 of 2025 forbids anyone else from providing electronic invoicing services in the country.

Three operational points follow, and each of them changes a procurement conversation:

1. One provider, both directions. The Guidelines state that a person in scope must appoint only one provider for both sending, that is accounts receivable, and receiving, that is accounts payable. Splitting the mandate across two vendors is not an option.
2. You start the onboarding, not the vendor. The Guidelines are explicit that onboarding is initiated by the person or government entity via EmaraTax, then completed with the chosen provider, who obtains your Peppol participant identifier.
3. You must keep the provider updated. Article 5(3) of MD No. 243 of 2025 gives you five business days from the FTA confirming any change to your registered data to notify your provider in writing.

Compliance does not end when the first XML document validates. Three continuing duties sit in Ministerial Decision No. 243 of 2025.

Storage. Article 11 requires every person subject to the system to store all electronic invoices, electronic credit notes and associated data within the State, for the period prescribed by the Tax Procedures Law and its Executive Regulation, Cabinet Decision No. 74 of 2023. Appendix 4 of the Guidelines adds two points to read before signing an archiving clause: your provider may store the data for you where the contract says so, but delegation does not transfer the legal obligation; and there is no rule that storage must sit at a particular layer of the network, provided retention, integrity and availability to the FTA are met.

System failure. Article 12 requires the issuer and the recipient to notify the Authority of a system failure within two business days.

Credit notes. Article 6(2) requires an electronic credit note where a transaction is cancelled, the consideration is reduced, the consideration is returned in whole or part, or an administrative or numerical error has occurred.

Cabinet Decision No. 106 of 2025 sets the penalties specific to the electronic invoicing system; ordinary VAT and tax-procedures penalties under Cabinet Decision No. 40 of 2017 continue to apply on top for invoicing failures generally. The first line of the table is the one worth planning around, because it accrues monthly and starts from your own appointment deadline.

The Ministry sets out four steps in chapter 9 of the Guidelines and expands them in Appendix 1. They are written as a project, and they are the honest order of work: nothing in step 3 can be tested until the contract in step 2 exists.

We do not publish a cost. Neither the Ministry of Finance nor the FTA publishes a price for electronic invoicing, and provider pricing is commercial and unpublished. Any figure quoted as "the cost of UAE e-invoicing" is somebody's estimate. What is documented is a floor on what you should receive: under Article 10(4) of Ministerial Decision No. 64 of 2025 every accredited provider has declared a commitment to supply 100 free electronic invoice exchange and reporting services per year from the date the end-user agreement is signed, and the Ministry's selection guidance recommends confirming that this is written into your contract.

We do not name or recommend providers. The register is the Ministry's to publish and it changes; we link to it rather than reproduce it.

There is no taxpayer-facing API to build against. As at 21 August 2026 the Ministry publishes the Guidelines, the mandatory-fields list and a selection guide; the integration specification your developers need is PINT AE, published by OpenPeppol, and the connection documentation belongs to your provider.
