UAE VAT invoice requirements for online stores in Dubai: what your checkout has to produce

UAE VAT invoice requirements for online stores start here: a VAT registered store in the UAE must issue and deliver a tax invoice for every taxable sale, and in most consumer orders a simplified tax invoice is allowed. That document needs the words “Tax Invoice”, your name, address and Tax Registration Number, the issue date, a description of what was sold, and the total with the VAT amount. Orders from VAT registered business customers usually need a full tax invoice with more detail. Separately, the Ministry of Finance’s electronic invoicing system is being phased in for business and government transactions, while sales to consumers are outside it for now.

This guide turns the Federal Tax Authority’s published guidance into the settings and templates a Dubai web shop has to get right. It reflects the FTA and Ministry of Finance material we opened in September 2026, and the rules on electronic invoicing in particular are still being rolled out.

UAE VAT invoice requirements: when a store must issue one

The FTA’s public clarification on tax invoices explains that Article 65 of the VAT Decree-Law requires a registered business making a taxable supply to issue an original tax invoice and deliver it to the recipient. The FTA adds that this applies without exception to standard rated supplies, and that offering to print an invoice only if the customer asks does not satisfy the requirement.

For a web shop, “deliver” in practice means the invoice reaches the customer as part of the order, typically attached to or linked from the confirmation email and available in the customer’s account. A checkout that only produces an order summary, with an invoice generated by the finance team later if someone requests it, is the arrangement the FTA has said is not enough.

The timing is set too. The FTA’s awareness guide on tax invoices states that the invoice must be issued and delivered within 14 calendar days from the date of each taxable supply. It also notes why the document matters on both sides: for the supplier it can help fix the date of supply and the tax period, and for a registered buyer it is the main evidence for recovering VAT.

Full or simplified: UAE VAT invoice requirements by order

UAE VAT invoice requirements let a registered supplier issue a simplified tax invoice in two cases, which the FTA summarises as follows.

• The customer is not registered for VAT. Most orders from individual shoppers fall here.
• The customer is registered for VAT and the consideration for the supply does not exceed the limit set out in Article 59(5) of the Executive Regulation.

So a store selling only to consumers can usually rely on simplified invoices, while a store that also serves trade buyers needs logic to switch to a full tax invoice. The simplest way to handle that is an optional company name and TRN field at checkout. When a TRN is entered and the order value is above the limit your adviser confirms, the store generates the full format. If you cannot build that switch, issuing full invoices for every order is a safe fallback, since a full invoice contains everything a simplified one does.

UAE VAT invoice requirements for your template fields

The table below compares the two formats using the FTA’s awareness guide and its public clarification. Use it as a checklist when you open your store’s invoice template or plugin settings.

Even where a field is not required on a simplified invoice, most stores include an invoice number and customer details anyway, because customer service, refunds and accounting all depend on them.

Line items, rounding and foreign currency at checkout

Three UAE VAT invoice requirements from the FTA’s public clarification regularly catch out store templates.

How lines are shown

On a full tax invoice, each line needs the net amount and the tax due. The FTA accepts that the VAT inclusive figure per line can be left out, as long as the invoice total including VAT is shown. On a simplified invoice the opposite is fine: lines can be shown at the gross price, with the total and the VAT contained in it shown at the bottom.

Rounding

Where VAT works out to a fraction of a fils, it may be rounded to the nearest fils on a mathematical basis. Because a full invoice calculates tax line by line, the FTA says rounding should also happen line by line. Stores that calculate VAT only on the basket total and then spread it across lines can end up with small mismatches, so test a basket of odd priced items before launch.

Selling in another currency

Many Dubai stores display prices in several currencies for visitors from abroad. The FTA’s clarification says that where an invoice is issued in a currency other than the dirham, it must show the tax payable in dirhams and the exchange rate applied, based on rates published by the UAE Central Bank for the date of supply. An invoice without that conversion is not a valid tax invoice for VAT purposes, so a currency switcher must feed the invoice template, not just the product pages.

Marketplaces, agents and repeat customers

UAE VAT invoice requirements do not change for marketplace sellers: the FTA’s E-Commerce VAT Guide confirms that the duty to invoice applies whether goods are sold directly or through an electronic marketplace. It also sets out when an agent can invoice instead of the principal supplier.

• A VAT registered agent making a supply on behalf of a principal may issue the tax invoice as if it made the supply, showing its own details, but the invoice should still refer to the principal supplier’s name and TRN.
• Only one tax invoice may be issued for any supply. If the marketplace or agent issues it, the principal should receive a copy and must not issue its own for the same sale.

If you sell on your own site and on a marketplace, check which party issues the invoice for marketplace orders, and make sure your own store is not generating a second one when those orders sync into your system. Our guide to selling on noon or Amazon.ae covers how the two channels differ more broadly.

Two further points from the FTA’s awareness guide affect subscription and repeat order stores. A summary monthly tax invoice must be issued where a supplier makes more than one supply to the same person in the same calendar month, and errors on tax invoices are corrected through tax credit notes or additional tax invoices rather than by editing the original.

Electronic invoicing: UAE VAT requirements as of September 2026

The electronic invoicing system is a different obligation from the tax invoice rules above. The FTA describes an e-invoice as a structured form of invoice data exchanged electronically between supplier and buyer and reported to the FTA, and says unstructured formats such as PDF files, Word documents, images, scans and emails are not e-invoices. The Ministry of Finance, which the FTA names as the official source on the programme, uses the PINT AE data format and the Peppol network, with invoices exchanged through Accredited Service Providers.

UAE VAT invoice requirements for electronic invoicing matter most here: for a shop selling only to the public, that last row is the important one today. For a store with trade accounts, wholesale buyers or corporate gifting clients, the business to business orders are likely to fall within the system on the relevant date, and the store’s order data will need to reach whichever provider the finance team appoints. Because dates have already been amended once, check the Ministry of Finance portal before planning around them.

A setup checklist for your store and web team

• Invoice template shows “Tax Invoice”, supplier name, address and TRN on every order.
• Numbering is sequential or unique and never resets when the plugin or theme is updated.
• Checkout has optional company name and TRN fields, and the template switches to the full format when needed.
• VAT is calculated and rounded per line and matches the order total exactly.
• Foreign currency orders show VAT converted to dirhams with the exchange rate used.
• Invoices are delivered with the order confirmation, stored securely, and available in the customer account.
• Refunds and corrections produce credit notes linked to the original invoice number.
• Marketplace orders imported into the store do not create a duplicate invoice.
• Order data can be exported in a structured form for a future electronic invoicing provider.

Meeting UAE VAT invoice requirements is easier with proof: retain a handful of test invoices from before launch and after every update. They are the quickest way to spot a plugin change that removed a field. Restaurants and cafes with printed menus face a related question about showing VAT in prices, covered in our guide to VAT inclusive prices on menus.
