UAE e-invoicing: the complete guide for 2026–2027

This guide is written by an implementation team, not by a software vendor or a provider selling its own platform. Every rule below links to the Ministry of Finance instrument it comes from, and the page is dated so you can tell what it reflects. If you only need your own dates, check your deadline first and come back for the detail.

What changed in October 2026

Three instruments changed the rules this month. Many guides published before October still describe the old position.

Earlier in 2026, Ministerial Resolution 66 of 2026 moved the ASP appointment deadline for large businesses from 31 July to 30 October 2026, without moving their 1 January 2027 go-live. The full list of instruments is on our sources page.

What UAE e-invoicing is, and what it is not

The Ministry of Finance defines an eInvoice as a structured form of invoice data, issued and exchanged electronically between supplier and buyer. It states that PDFs, Word documents, images, scanned copies and emails are not eInvoices (mof.gov.ae).

In practice this means three things change:

1. The format. Invoices become XML data in the UAE’s PINT AE specification, based on Peppol.
2. The route. They travel from your Accredited Service Provider (ASP) to your customer’s ASP over the Peppol network, instead of by email.
3. The reporting. Tax data from each invoice reaches the Federal Tax Authority as it is exchanged, not months later in a VAT return.

A PDF copy can still be sent for convenience — by email, or by WhatsApp — but it is not the invoice of record.

Deadlines by phase

Dates come from Ministerial Decision 244 of 2025 as amended by Ministerial Resolution 66 of 2026.

How the AED 50 million test is measured

The test uses revenue for the most recent accounting period (KPMG). Groups should test each legal entity, and a business close to the line should document which period it used. The wave checker works this out per entity and shows the days remaining.

If a deadline has already passed

Missing the appointment or implementation date carries AED 5,000 for each month or part of a month of delay. The penalty keeps running until you comply, so appointing an ASP late is still far cheaper than not appointing one. The deadlines page has every date, and the penalty calculator estimates your exposure.

Who is in scope

The mandate covers business-to-business (B2B) and business-to-government (B2G) transactions, including those by non-residents required to issue tax invoices in the UAE (PwC). Supplies to consumers (B2C) are not covered; no date has been set for them.

A person whose transactions are excluded may join voluntarily. Once it does, the rules apply to it in full, except the violations and penalties (Ministerial Decision 197 of 2026, Article 4(3)).

Free zone companies

Free zone status is not an exemption: scope follows the transaction, not the licence. Where a free zone is involved, the invoice identifies the beneficiary as well as the customer. More on the free zone page.

VAT groups

Each member of a Tax Group onboards separately with its own Tax Identification Number, and members may use different ASPs. Invoices between members are excluded for the first 24 months; invoices to customers outside the group are in scope from the group’s go-live date.

Government suppliers

If you sell to government, you are in scope on your own business’s date, which can be earlier than the government entity’s 1 October 2027 date. See government suppliers.

How it works: the five-corner model

The UAE model is called Decentralised Continuous Transaction Control and Exchange (DCTCE). It has five corners (mof.gov.ae):

1. Corner 1 — the supplier sends invoice data to its ASP.
2. Corner 2 — the supplier’s ASP validates it, converts it to the UAE XML format if needed, delivers it to the buyer’s ASP and reports a Tax Data Document to the authority.
3. Corner 3 — the buyer’s ASP validates the invoice, sends a status message back to Corner 2 and delivers the invoice to the buyer.
4. Corner 4 — the buyer receives structured data into its own system.
5. Corner 5 — the Federal Tax Authority receives the Tax Data Documents.

If the buyer’s ASP finds the invoice invalid, it sends a negative status to the supplier’s ASP and the authority instead of reporting the tax data. Your billing team needs a process for these rejections — they are the most common day-one problem.

Technical requirements

PINT AE and the mandatory fields

PINT AE is the UAE specialisation of Peppol’s international invoice model. The authority’s technical guidance lists 51 mandatory fields for an electronic tax invoice, with an adapted list for commercial (non-tax) invoices (KPMG). The official document is the UAE Electronic Invoice Mandatory Field Requirements v1.0 on the Ministry of Finance page. Most gaps sit in master data: buyer TINs, item identifiers, units of measure and tax category codes.

Your Peppol identifier

Your electronic address is 0235 followed by your 10-digit Tax Identification Number (TIN), which is the first 10 digits of your Tax Registration Number (Electronic Invoicing Guidelines v1.0).

Special buyer addresses

The second row matters between 1 January and 1 July 2027: a large supplier already live will be invoicing smaller customers who are not yet onboarded.

Foreign currency

Invoices can be in any currency, but VAT and the gross total must also be shown in dirhams, converted at the Central Bank of the UAE rate, and the tax accounting currency field becomes mandatory.

Timing rules

Ministerial Decision 197 of 2026 replaced Article 6(5) of Ministerial Decision 243: e-invoices and credit notes must be issued and transmitted through the system within 14 business days of the transaction, subject to Article 6(4), which ties VAT-registered persons to the VAT law’s invoicing timeline. If you are VAT-registered, your existing tax invoice deadline still applies.

Credit notes, self-billing and other special cases

• Credit notes. A negative invoice is not allowed; a negative total must be documented with an electronic credit note. One credit note can reference several invoices.
• Self-billing. Allowed for tax invoices only, with an agreement between supplier and buyer, a VAT-registered supplier and a buyer already on the system. There is no self-billed commercial invoice.
• Disclosed agents. The supplier remains responsible for the invoice.
• Summary and continuous supplies. Permitted, and flagged in the invoice’s transaction-type field.
• Advance payments and retentions. The guidelines updated in June 2026 cover invoicing an advance, invoicing the balance with a reference to it, and invoicing a retention when it falls due (PwC). This is common in construction and contracting, and worth testing early.

Choosing an Accredited Service Provider

Both the issuer and the recipient of an e-invoice need an ASP, and you appoint one ASP for both sending and receiving. Only providers on the Ministry of Finance register may be used: 80 were listed on 27 October 2026. Search them on our ASP list.

The decision usually turns on your accounting system. If its vendor is itself accredited, the shortest route may be built in; if not, you need a connector or an integration. Our system guides cover Zoho Books, Tally, QuickBooks, Odoo, SAP and Dynamics 365, and how to choose an ASP lists the questions to ask any provider. We are not an ASP, and no ASP pays us to appear on this site.

EmaraTax onboarding, step by step

Onboarding is started by the business, not by the ASP:

1. Confirm your TIN (the first 10 digits of your TRN).
2. Sign a contract with an accredited ASP.
3. Log in to EmaraTax with UAE PASS and open the e-invoicing section.
4. Select your ASP so it can activate your 0235 identifier.
5. Map your invoice data to PINT AE and test with your ASP, including rejections and credit notes.
6. Go live on your phase date, and tell your ASP about changes to your registered details within 5 business days.

Storage and record keeping

You must keep e-invoices, credit notes and their data for the period set by the Tax Procedures Law and be able to produce them to the authority on request. Since 1 October 2026 the rule no longer requires that this data be stored inside the UAE (Ministerial Decision 197 of 2026, Article 11). Your ASP may store data for you, but the obligation stays with your business.

Penalties

Cabinet Decision 106 of 2025 sets the penalties.

Voluntary participants are outside the penalty regime. Estimate your exposure.

Readiness checklist

Work through these in order; the full readiness checklist has 30 checks.

1. Confirm your phase per legal entity.
2. Clean customer master data: TINs, addresses, Peppol identifiers.
3. Check your accounting system’s route to an ASP.
4. Appoint an ASP and onboard on EmaraTax.
5. Map and test PINT AE, including credit notes, exports and special cases.
6. Write the rejection-handling process and name an owner.
7. Train billing and payables staff before go-live.

Claims that are out of date

If you read any of these elsewhere, check the date of the page:

• “Large businesses go live in July 2026.” Only the pilot and voluntary adopters started then.
• “Appoint your ASP by 31 July 2026.” Moved to 30 October 2026.
• “E-invoice data must be stored in the UAE.” Removed from 1 October 2026.
• “You must report system failures within two business days.” Repealed from 1 October 2026.
• “Full rollout in 2028.” The last published date is 1 October 2027, for government entities.

Frequently asked questions

When is e-invoicing mandatory in the UAE?

Businesses with revenue of AED 50 million or more go live on 1 January 2027, all other businesses in scope on 1 July 2027, and government entities on 1 October 2027.

What is the ASP appointment deadline?

30 October 2026 for businesses with revenue of AED 50 million or more, and 31 March 2027 for everyone else in scope, including government entities.

Is B2C included?

No. Supplies to consumers are outside the current mandate, and no date has been set for them.

Do buyers need an ASP too?

Yes. Every business in scope appoints one ASP that handles both sending and receiving e-invoices.

What is my Peppol ID?

0235 followed by your 10-digit TIN, which is the first 10 digits of your Tax Registration Number.

Must e-invoice data be stored in the UAE?

Not since 1 October 2026. Records must still be kept for the Tax Procedures Law period and produced to the Federal Tax Authority on request.

Do invoices inside a VAT group need to be e-invoices?

Transactions between members of the same Tax Group are excluded for 24 months from 1 January 2027. Invoices to customers outside the group are in scope.

Is a PDF invoice still valid?

Not as the invoice of record for in-scope transactions. A PDF copy can accompany the e-invoice, and a PDF tax invoice is also required when the buyer is not yet on the system.

Is E-Invoicing UAE a government website or an ASP?

Neither. E-Invoicing UAE is an independent service operated by SHORIQ TECH LLC. We help businesses choose and connect to an accredited provider; we are not a tax advisor.
