UAE Tax Invoice Requirements: Full Checklist for 2026

If you are registered for VAT in the UAE, every invoice you send to a customer is also a legal document. The Federal Tax Authority (FTA) expects certain details on it, and your customer needs a valid tax invoice to recover the VAT they paid. This guide explains the UAE tax invoice requirements in plain language: what must appear on a full and a simplified tax invoice, when you must issue it, how to handle foreign currencies, and what is changing with e-invoicing.

What is a tax invoice in the UAE?

A tax invoice is a written or electronic document that records a taxable supply of goods or services. Under the UAE VAT rules, it does two jobs at the same time:

• For the seller, it helps fix the date of supply, which decides the tax period in which you must pay the output VAT.
• For the buyer, it is the main evidence needed to recover input VAT. If the invoice is missing key details, your VAT-registered customer may not be able to claim the tax back, and they will ask you to reissue it.

Only a VAT-registered business (a "registrant") can issue a tax invoice. If you are not registered, you must not show VAT or a TRN on your invoices; use a normal commercial invoice instead.

The rules on content are set out in Article 59 of the VAT Executive Regulation (Cabinet Decision No. 52 of 2017), which was updated by Cabinet Decision No. 100 of 2024 with effect from 15 November 2024. The FTA has also published a short guide on tax invoices, which is the best official starting point.

Full tax invoice: mandatory fields checklist

A full (standard) tax invoice is needed for most sales to VAT-registered customers. Use this checklist before you send one:

1. The words "Tax Invoice" clearly displayed.
2. Your name, address and Tax Registration Number (TRN) as the supplier.
3. The customer's name and address, and their TRN if they are VAT registered.
4. A sequential invoice number (or a unique number) that identifies the invoice and its place in your sequence.
5. The date of issue.
6. The date of supply, but only if it is different from the date of issue.
7. A description of the goods or services supplied.
8. For each line: the quantity or volume, the unit price, the VAT rate and the amount payable in AED.
9. The amount of any discount offered.
10. The gross amount payable in AED.
11. The total VAT in AED, together with the exchange rate used and its source if the invoice is in another currency.
12. If the customer must account for the VAT under the reverse charge, a statement saying so and a reference to the relevant provision of the VAT law.

Small details matter. A missing customer TRN or a missing VAT rate per line are among the most common reasons a business customer rejects an invoice.

Simplified tax invoice: when you can use it

A simplified tax invoice is a shorter version, designed mainly for retail and walk-in sales. You may issue one instead of a full tax invoice when:

• the customer is not registered for VAT (there is no value limit in this case), or
• the customer is registered for VAT and the total consideration, including VAT, is AED 10,000 or less.

The FTA's own examples make this clear: an individual buying AED 40,000 of clothes can receive a simplified invoice, but a VAT-registered shop buying AED 10,001 of clothes must receive a full tax invoice. Professional sources also note that, since the 2024 amendments, a simplified invoice cannot be used where the reverse charge applies.

What a simplified tax invoice must show

• The words "Tax Invoice" in a prominent place.
• Your name, address and TRN.
• The date of issue.
• A description that is sufficient to identify the goods or services.
• The total amount payable and the VAT charged.

Deadline, currency and language rules

Issue the invoice within 14 days

The FTA states that a tax invoice must be issued and delivered within 14 calendar days from the date of supply. Do not wait until the customer pays. If you raise invoices at month-end, check that no supply falls outside the 14-day window.

Invoicing in USD, EUR or another currency

You can price and invoice in a foreign currency, but the VAT figures must also be shown in UAE dirhams. The FTA says the amount must be converted to AED using an exchange rate approved by the Central Bank of the UAE, and the invoice must show the rate used. If the VAT works out to a fraction of a fils, round it to the nearest fils.

Can the invoice be in English only?

The list of mandatory fields in Article 59 does not require Arabic. Under the Tax Procedures Executive Regulation (Cabinet Decision No. 74 of 2023), the FTA may accept records and documents in English and may ask for some or all of them to be translated into Arabic. In practice, an English invoice is acceptable, but be ready to provide a translation if the FTA asks. A bilingual Arabic and English invoice avoids that step and is often appreciated by local customers.

Worked example: a 5% VAT tax invoice

A Dubai web agency (VAT registered) builds a website for a VAT-registered trading company. The agency gives a small discount. Here is how the figures look on the invoice:

The total is AED 7,875, which is below AED 10,000, so the rules would allow a simplified invoice here. However, the customer wants to recover VAT and needs full details for its records, so a full tax invoice is the better choice. If the same job were invoiced in US dollars, the invoice would still need to show the VAT (and the total) in AED, plus the exchange rate and its source.

Common mistakes to avoid

• Using the title "Invoice" instead of "Tax Invoice". The exact words are a mandatory field.
• Forgetting the customer's TRN on sales to registered businesses.
• Showing VAT only in a foreign currency, with no AED amount or exchange rate.
• Breaking the number sequence, for example by deleting a cancelled invoice. Keep the number and correct the mistake with a tax credit note instead.
• Editing an invoice after sending it. The FTA expects errors to be corrected through tax credit notes or additional tax invoices.
• Charging VAT without being registered. Only registrants may show VAT and a TRN.
• Issuing late. The 14-day clock starts from the date of supply, not the date of payment.

What is coming: UAE e-invoicing

The UAE is moving from PDF and paper invoices to structured electronic invoices exchanged through Accredited Service Providers (ASPs). The rules are set out in Ministerial Decisions No. 243 and No. 244 of 2025, published by the Ministry of Finance. Under Decision No. 244:

Two points matter for small businesses. First, business-to-consumer (B2C) transactions are outside the system for now, and a business that only sells to consumers is not in scope until the Minister decides otherwise. Second, if you sell to other businesses, you are likely to be in the July 2027 phase, which means choosing an ASP by 31 March 2027. The ASP deadline extension for large businesses was reported by Deloitte, and the 1 January 2027 go-live date did not change. Dates can move, so check the Ministry of Finance and FTA websites before you plan.

Until your phase begins, a clear PDF tax invoice that contains every field above remains the normal way to invoice.

Key takeaways

• Use a full tax invoice for registered customers when the total is above AED 10,000; a simplified invoice is fine for unregistered customers and smaller B2B sales.
• Always show "Tax Invoice", your TRN, a sequential number, and VAT in AED.
• Issue the invoice within 14 days of the supply.
• Foreign-currency invoices need the AED VAT amount, the exchange rate and its source.
• English invoices are accepted, but the FTA may ask for an Arabic translation.
• B2B businesses below AED 50 million revenue should plan for e-invoicing by 1 July 2027.

Frequently asked questions

Do I need to show my TRN on every invoice?

Yes. Both full and simplified tax invoices must show the supplier's name, address and TRN.

Can I issue one invoice for several deliveries in a month?

The FTA's tax invoice guidance refers to summary tax invoices for several supplies to the same customer in the same calendar month. If you use them, make sure each one still contains all the required details.

Is a PDF sent by email or WhatsApp a valid tax invoice?

Yes, tax invoices can be issued electronically, as long as the origin and content cannot be changed and you keep a copy under the record-keeping rules. This will change for B2B sales once your e-invoicing phase starts.

What if I made a mistake on an invoice I already sent?

Do not edit or delete it. Issue a tax credit note (or an additional tax invoice if you undercharged) that refers to the original invoice.

If you need a clean, compliant layout, the tax invoice generator includes the "Tax Invoice" title, TRN fields, per-line VAT and AED totals. Our UAE invoice generator also supports bilingual Arabic and English PDFs.
