UAE Tax Invoice Format 2026: Mandatory Fields & E-Invoicing

The UAE tax invoice format is set by Article 59 of the VAT Executive Regulation, and in 2026 it is changing faster than at any point since VAT began in 2018. A valid tax invoice still needs the supplier's TRN, a sequential number, line-level VAT and AED totals.

UAE Tax Invoice Format in 2026: Mandatory Fields and What Changes Under E-Invoicing

Introduction

But from 1 January 2027, large businesses must issue that same invoice as a structured PINT AE e-invoice through an Accredited Service Provider (ASP), with 51 mandatory data fields.

This guide covers both: the fields every UAE tax invoice needs today, and exactly what changes once e-invoicing applies to you.

Quick answer: what must a UAE tax invoice include?

A full UAE tax invoice must show the words "Tax Invoice", the supplier's name, address and TRN, the buyer's name, address and TRN (if registered), a sequential invoice number, the issue date, the date of supply (if different), a description of each item, the unit price, quantity, VAT rate and amount per line in AED, any discount, the total amount payable and the total VAT in AED.

Once e-invoicing applies, the invoice must also be a structured PINT AE XML file carrying 51 mandatory fields, including your Peppol endpoint and transaction-type flags.

What is a tax invoice in the UAE, and who must issue one?

A tax invoice is the document a VAT-registered business (a "registrant") issues to record a taxable supply. It is also the buyer's main evidence for recovering input VAT, so a missing field can cost your customer their VAT credit.

The rules come from two instruments:

• Federal Decree-Law No. 8 of 2017 on VAT, Article 65, which requires registrants to issue tax invoices, and Article 67, which sets the 14-day deadline.
• The VAT Executive Regulation (Cabinet Decision No. 52 of 2017), Article 59, which lists exactly what a tax invoice must contain.

Two recent amendments matter for 2026:

Cabinet Decision No. 100 of 2025,in force since 29 September 2025, added Article 59(16). It switches off several invoice relaxations once a business issues e-invoices.

Federal Decree-Law No. 16 of 2025,in force since 1 January 2026, removed the need to issue self-invoices for reverse-charge purchases. You now keep the supplier's invoice and import documents as evidence instead.

Mandatory fields on a UAE tax invoice in 2026

Article 59(1) of the VAT Executive Regulation lists 12 particulars for a full tax invoice. Article 59(2) lists a shorter set for a simplified tax invoice. Use the table below as a checklist against your invoice template or ERP print layout.

Three rules sit around the fields:

• Timing: issue the tax invoice within 14 days of the date of supply (Article 67 of the VAT Law).
• Currency: you may invoice in USD or any other currency, but the VAT amount must be shown in AED, using the UAE Central Bank exchange rate on the date of supply.
• Zero-rated supplies: under the current rules you can skip a tax invoice for a wholly zero-rated supply if your records show its details (Article 59(3)). This relief ends once you move to e-invoicing (see below).

When can you issue a simplified tax invoice?

Under Article 59(5), a simplified tax invoice is allowed in two cases:

1. The recipient is not VAT-registered (typical in retail and B2C).
2. The recipient is registered, but the consideration for the supply does not exceed AED 10,000.

Above AED 10,000 to a registered buyer, you must issue a full tax invoice.

Tax credit notes follow a parallel checklist in Article 60. They need the words "Tax Credit Note", supplier and recipient details, a sequential number, the issue date, the value of the supply shown on the original invoice, the corrected amount, the VAT difference in AED, and a brief explanation of the adjustment with a reference to the original tax invoice.

For how this works once credit notes become electronic, see our guide on designing credit notes and corrections for UAE e-invoicing.

Language: Article 59 does not require Arabic. English invoices are accepted, but the Federal Tax Authority (FTA) can ask for an Arabic translation of any record during an audit.

What changes under UAE e-invoicing?

E-invoicing does not replace Article 59. It changes the form of the invoice and removes most of the flexibility around it. The Ministry of Finance is clear that PDFs, Word files, scans and emails are not e-invoices. An e-invoice is structured data in the PINT AE format (the UAE version of the Peppol standard), exchanged through ASPs and reported to the FTA.

1. Who and when

The Phase 1 ASP deadline was moved from 31 July 2026 to 30 October 2026 by Ministerial Resolution No. 66 of 2026. The 1 January 2027 go-live did not move. The phases themselves come from Ministerial Decision No. 244 of 2025.

2. Simplified invoices and FTA waivers disappear

Article 59(16), added by Cabinet Decision No. 100 of 2025, switches off several clauses of Article 59 for any business issuing e-invoices, whether mandatorily or voluntarily. In practice:

• No more simplified tax invoices. Every e-invoice carries the full data set, even for B2C or sub-AED 10,000 sales.
• No more FTA approvals to leave fields off an invoice.
• Zero-rated supplies need an invoice. An export shipment now needs its own e-invoice, even with no VAT charged.

3. 51 mandatory data fields instead of 12 particulars

The MoF's UAE Electronic Invoice Mandatory Fields, version 1.1 (28 October 2026) lists 51 mandatory fields for an electronic tax invoice. Most are the Article 59 particulars in structured form. The genuinely new ones are:

• Invoice type code and invoice transaction type code: an 8-flag string marking free zone, deemed supply, margin scheme, summary invoice, continuous supply, disclosed agent billing, e-commerce and exports.
• Seller and buyer electronic address: your Peppol endpoint, based on your 10-digit TIN, with the scheme identifier 0235. Our explainer on TIN vs TRN for EmaraTax onboarding covers why these differ.
• Legal registration identifier and type: trade licence (TL), Emirates ID (EID), passport (PAS) or Cabinet Decision (CD).
• Payment due date and payment means type code.
• Business process type and specification identifier: fixed technical values.
• Line-level codes: unit of measure code, item gross and net price, price base quantity, and tax category code per line.
• Line VAT and line total in AED, even when the invoice currency is not AED.

4. A 14-business-day deadline and new exclusions

Ministerial Decision No. 197 of 2026, in force since 1 October 2026, sets two rules that change day-to-day invoicing:

• E-invoices and e-credit notes must be issued and transmitted within 14 business days of the transaction date.
• Transactions between members of the same VAT tax group are excluded for 24 months from 1 January 2027. Other exclusions include sovereign government activity, airline passenger tickets, exempt or zero-rated financial services, and air cargo under an airway bill (for 24 months).

UAE tax invoice format: before vs after e-invoicing

Common tax invoice mistakes, and how to fix them before 2027

Most e-invoice rejections will not come from the XML. They will come from data that was "good enough" on a PDF. These are the issues we see most often in ERP invoice data:

1. Missing or wrong buyer TRN. Fine on a PDF, but a rejected e-invoice in 2027. Validate customer TRNs now.
2. Treating TRN and TIN as the same field. The Peppol endpoint uses the 10-digit TIN, not the 15-digit TRN.
3. Free-text units of measure. "Box" or "pcs" must map to a coded unit of measure.
4. No AED values on foreign-currency lines. Line VAT and line totals in AED become mandatory.
5. Simplified invoices built into POS or billing flows. These must move to full invoices once your phase starts.
6. Gaps in invoice numbering across entities, sites or document sequences.
7. Skipping invoices for zero-rated exports. Each shipment will need its own e-invoice.

FAQs on the UAE tax invoice format

What is the correct tax invoice format in the UAE?

A full UAE tax invoice must follow Article 59(1) of the VAT Executive Regulation. It shows "Tax Invoice", supplier and buyer names, addresses and TRNs, a sequential number, issue and supply dates, item descriptions, per-line price, quantity, VAT rate and AED amount, discounts, the total payable and total VAT in AED.

Is a PDF invoice still valid in the UAE in 2026?

Yes, until e-invoicing applies to your business. Phase 1 businesses (revenue of AED 50 million or more) must issue structured e-invoices from 1 January 2027, and other businesses from 1 July 2027. After that, a PDF is not a valid e-invoice.

How many mandatory fields does a UAE e-invoice have?

An electronic tax invoice has 51 mandatory fields under the MoF's Mandatory Fields specification, version 1.1, dated 28 October 2026. A commercial (non-tax) e-invoice has 49. Most map to the existing Article 59 particulars; the rest are Peppol technical fields.

Can I still issue a simplified tax invoice under e-invoicing?

No. Article 59(16), added by Cabinet Decision No. 100 of 2025, disapplies the simplified tax invoice rules for any business issuing e-invoices. Every e-invoice must carry the full mandatory data set, whatever the value or customer type.

Do I need to show VAT in AED if I invoice in USD?

Yes. Under Article 59, the VAT amount must be shown in AED with the exchange rate used. Under e-invoicing, the line VAT amount and line total must also be stated in AED.

What is the deadline for issuing a tax invoice in the UAE?

Today it is 14 days from the date of supply. Under e-invoicing, Ministerial Decision No. 197 of 2026 requires e-invoices to be issued and transmitted within 14 business days of the transaction date.

Do I still need a self-invoice for reverse-charge purchases?

No. Since 1 January 2026, Federal Decree-Law No. 16 of 2025 removed the self-invoicing requirement. Keep the supplier's invoice and import documents as evidence instead.

Get your tax invoices e-invoicing ready

The UAE tax invoice format is not getting simpler; it is getting stricter and more structured. The 12 Article 59 particulars remain the foundation, but from 2027 they travel as 51 data fields, within 14 business days, with no simplified invoices or waivers to fall back on. The gap between those two formats lives in your ERP master data and invoice setups.
