UAE eInvoicing
What the mandate requires, when it applies to you, and how payment connects to the invoice record.
The timeline
What the mandate actually requires
Three things, and the first surprises people.
A PDF is not an electronic invoice. The Ministry of Finance is explicit that unstructured formats do not qualify. An eInvoice is structured XML in the PINT AE format — the UAE's Peppol International Invoice specification, based on UBL 2.1 — exchanged across the network. A PDF emailed to a customer does not meet the requirement, no matter how it was produced.
You must appoint an Accredited Service Provider. You cannot connect to the network yourself. The ASP converts your invoices to PINT AE, validates them against the prescribed fields, transmits them to the buyer's ASP and reports the tax data. An ASP must itself be a certified Peppol Service Provider.
It is reporting, not clearance. Invoices do not need approval from the Federal Tax Authority before you can issue them. Reporting data flows to the FTA through the network, giving near-real-time visibility without pre-clearance of each invoice. That is a lighter model than some neighbouring jurisdictions operate.
Who it applies to
| Phase | Who | ASP appointed by | Go-live |
|---|---|---|---|
| Pilot | Selected taxpayers, voluntary | — | 1 July 2026 |
| Phase 1 | Annual revenue AED 50m or more | 30 October 2026 | 1 January 2027 |
| Phase 2 | Annual revenue below AED 50m | 31 March 2027 | 1 July 2027 |
| Phase 3 | Government entities | 31 March 2027 | 1 October 2027 |
The mandate applies broadly to businesses transacting in the UAE regardless of VAT registration status, unless specifically excluded. Participation is keyed to a Tax Identification Number — the first ten digits of your Corporate Tax Registration Number. Businesses not otherwise required to register for Corporate Tax still need to obtain a TIN. B2C transactions remain outside scope until further notice.
Where iSAP Exchange fits — and where it does not
What the mandate governs is how an invoice is transmitted. What it does not govern is how that invoice connects to the money that settles it. That gap is where reconciliation work lives — and it is the part most finance teams still do by hand.
Through our ERP integration, a payment made via iSAP Exchange updates the corresponding invoice record in your system of record. The document and the transaction stay in step, rather than being matched a week later from two different screens.
Put simply: your ASP makes the invoice compliant. We make the payment and the invoice agree with each other.
What to do now
- Confirm your phase. Above or below AED 50 million in annual revenue decides your deadlines.
- Check you hold a TIN. Required for participation even if you are not otherwise registered for Corporate Tax.
- Appoint an ASP. Mandatory, with a deadline. The Ministry of Finance publishes a list of pre-approved providers.
- Check your ERP can produce the mandatory fields. The FTA's semantic model covers invoice details, seller and buyer identification, totals, tax breakdown and line-level data.
- Decide how payment data reaches the invoice record. This is where we can help — see payment solutions or write to us. Trading with Europe too? See Europe eInvoicing.

Frequently asked questions
When do I have to comply?
It depends on your revenue. Businesses with annual revenue of AED 50 million or more go live on 1 January 2027 and must appoint an Accredited Service Provider by 30 October 2026. Businesses below that threshold go live on 1 July 2027 with an ASP appointed by 31 March 2027. Government entities follow on 1 October 2027. The voluntary pilot has been running since 1 July 2026.
Wasn't the ASP deadline in July?
It was. On 10 May 2026 the Ministry of Finance extended the ASP appointment deadline for businesses with revenue of AED 50 million or more from 31 July 2026 to 30 October 2026. The mandatory go-live date of 1 January 2027 did not move.
What is an Accredited Service Provider?
An ASP is a provider accredited by the Ministry of Finance to connect your business to the Peppol network. It converts your invoices into the required PINT AE format, validates them against the prescribed fields, transmits them to the buyer's ASP and reports the tax data. An ASP must itself be a certified Peppol Service Provider. Appointing one is mandatory — you cannot connect to the network directly.
Is a PDF invoice an electronic invoice?
No. The Ministry of Finance is explicit that unstructured formats do not qualify. An eInvoice under the mandate is structured XML in the PINT AE format, the UAE's Peppol International Invoice specification, exchanged through the network. A PDF sent by email is not an eInvoice, however it was produced.
Does the tax authority have to approve each invoice first?
No. This is a reporting and structured-exchange model, not a clearance model. Invoices do not require approval before they can be issued. Reporting data reaches the Federal Tax Authority through the network, giving near-real-time visibility without pre-clearance of individual invoices.
Does it apply if we are not VAT registered?
The mandate applies broadly to businesses transacting in the UAE regardless of VAT registration status, unless specifically excluded. Participation is based on a Tax Identification Number — the first ten digits of the Corporate Tax Registration Number. Businesses not otherwise required to register for Corporate Tax still need to obtain a TIN to participate.
Does it cover sales to consumers?
B2C transactions remain outside the scope of the mandate until further notice, alongside a limited set of announced exclusions. The mandate covers B2B and B2G.
Is iSAP Exchange an Accredited Service Provider?
No, and we would not want that to be unclear. You appoint an ASP separately; it handles format conversion, validation and transmission. What iSAP Exchange does is connect the payment to the invoice record in your ERP, so that when a payment is made the corresponding invoice record is updated rather than reconciled by hand later.
What does iSAP actually add, then?
Reconciliation. The mandate governs how an invoice is transmitted; it does not connect that invoice to the money that settles it. Through our ERP integration, a payment made via iSAP updates the invoice record in your system of record, so the document and the transaction stay in step without manual matching.
What should we be doing now?
If you are above AED 50 million, appointing an ASP is the immediate step, since the deadline is 30 October 2026. Alongside that: confirm you hold a TIN, check that your ERP can produce the mandatory fields, and decide how payment data will reach the invoice record. That last piece is where we can help.
