The United Arab Emirates introduced VAT on 1 January 2018, and with it a set of specific rules about what an invoice must contain. Businesses that traded happily for years on simple invoices suddenly had a compliance document to produce, and the transition still shows: rejected invoices in the UAE are usually missing the same two or three fields.
The rate is 5% — low by international standards — but the documentation requirements are not relaxed because the rate is small. This guide covers what a UAE tax invoice must show, when the simplified version is allowed, how free zones change the picture, and what is coming with e-invoicing.
This is general information, not tax or legal advice. UAE VAT is administered by the Federal Tax Authority and the rules around free zones in particular are fact-specific. Confirm your position with the Federal Tax Authority or a registered tax agent.
Do you need to register for VAT?
Registration turns on your taxable turnover over a rolling twelve months:
- Mandatory once taxable supplies and imports exceed AED 375,000
- Voluntary once they exceed AED 187,500
Below the voluntary threshold you cannot register, cannot charge VAT, and must not issue anything called a tax invoice. Issue a normal commercial invoice instead.
Once registered you receive a Tax Registration Number (TRN) — a 15-digit number that must appear on every tax invoice you issue. Your customers will check it. The FTA publishes a TRN verification tool, and larger UAE businesses routinely validate a supplier's TRN before processing payment.
What a full tax invoice must contain
The requirements sit in Article 59 of the Executive Regulations. A full tax invoice needs:
- The words "Tax Invoice" displayed clearly
- Your name, address and TRN as the supplier
- The recipient's name, address and TRN, where they are registered for VAT
- A sequential tax invoice number that uniquely identifies the document
- The date of issue, and the date of supply if it differs
- A description of the goods or services supplied
- For each line: the unit price, quantity, the rate of tax, and the amount payable — expressed in AED
- Any discount offered
- The gross amount payable, in AED
- The tax amount payable, in AED, together with the exchange rate applied if the supply was in another currency
- Where the customer accounts for the tax themselves, a statement to that effect with a reference to the relevant provision
Two of these cause most of the friction.
The tax amount must be stated in AED. Even when you invoice in US dollars — which is extremely common in the UAE — the VAT figure has to be shown in dirhams, with the exchange rate you used. An invoice in USD with the VAT only in USD is incomplete.
The recipient's TRN is required when they are registered. Omitting it is one of the most common reasons a UAE accounts department returns an invoice, because without it their input tax recovery is at risk.
The simplified tax invoice
A shorter form is permitted where:
- the recipient is not registered for VAT, or
- the recipient is registered but the consideration does not exceed AED 10,000
A simplified tax invoice needs the words "Tax Invoice", your name, address and TRN, the date of issue, a description of what was supplied, and the total consideration with the tax amount shown.
You do not need the recipient's details or a running invoice number. This is what most retail receipts in the UAE are.
Timing: the 14-day rule
A tax invoice must be issued within 14 days of the date of supply. This is a real deadline rather than a guideline, and it is easy to breach when a project completes at month end and invoicing waits for an approval cycle.
The date of supply is generally the earliest of: goods being delivered or made available, services being completed, receipt of payment, or the date stated on the invoice.
Zero-rated, exempt, and out of scope
Not everything carries 5%.
Zero-rated (0%) supplies include exports of goods and services outside the GCC implementing states, international transport, certain investment-grade precious metals, newly constructed residential property within the first three years, and defined education and healthcare services. You still issue a tax invoice, still file returns, and can still recover input VAT.
Exempt supplies include certain financial services, bare land, local passenger transport, and residential property beyond the initial period. Here you fall outside the VAT system for those supplies and cannot recover related input tax.
The distinction matters commercially, not just administratively: zero-rated preserves your input tax recovery, exempt does not.
Exported services deserve particular care. Whether a service supplied to a non-resident qualifies for zero-rating depends on conditions including where the recipient is established and where the service is actually performed or enjoyed. It is not automatic simply because the client is abroad.
Free zones: designated is not the same as free
This is the most misunderstood area of UAE VAT.
There are many free zones in the UAE, but only a specific subset are Designated Zones for VAT purposes — a list set by Cabinet Decision. Being in a free zone does not, on its own, put you outside VAT.
For companies in an ordinary free zone, VAT works essentially as it does on the mainland. For those in a Designated Zone, certain transfers of goods within or between zones may be treated as outside the scope of UAE VAT — but services supplied from a Designated Zone are generally treated as supplied within the UAE and taxed normally.
If your business is in a free zone, confirm whether it is a Designated Zone, and do not assume the treatment extends to services. Getting this wrong in either direction is expensive.
Reverse charge on imports
When a UAE business imports goods or services from outside the country, the reverse charge mechanism usually applies. The UAE recipient accounts for the VAT on their own return rather than the foreign supplier registering locally.
If you are a foreign business supplying services to a VAT-registered UAE customer, you generally do not register for UAE VAT and do not charge it. Issue a normal commercial invoice; your client self-accounts. Say so on the invoice to avoid the question coming back.
E-invoicing
The UAE is introducing a national electronic invoicing system for business-to-business and business-to-government transactions, built on the Peppol framework with an accredited service provider model. Implementation is phased, with the framework and provider accreditation established ahead of the reporting obligations.
Timelines have moved during development, so confirm current dates with the Ministry of Finance rather than relying on any single published schedule. The practical preparation is the same regardless: clean master data, accurate TRNs on file for your customers, and an invoicing process that can emit structured data rather than only PDFs.
Record keeping
VAT records must generally be retained for five years, extended for real estate to fifteen. Records must be available for FTA inspection.

FAQ
What is a TRN and where does it go on the invoice?
The Tax Registration Number is the 15-digit identifier the Federal Tax Authority issues when you register for VAT. It must appear on every tax invoice you issue. Include your customer's TRN too when they are registered — its absence is a common reason invoices are returned.
Can I invoice a UAE client in US dollars?
Yes, and it is common. But the VAT amount must still be shown in AED, along with the exchange rate you applied. Showing the tax only in the foreign currency makes the invoice incomplete.
Does being in a free zone mean I do not charge VAT?
No. Only specific Designated Zones receive special treatment, and even then it applies mainly to goods. Services supplied from a Designated Zone are generally treated as supplied inside the UAE and taxed at the standard rate. Check whether your zone is on the Cabinet Decision list before assuming anything.
When must I issue the tax invoice?
Within 14 days of the date of supply. The date of supply is usually the earliest of delivery, completion of the service, receipt of payment, or the invoice date.
I am a foreign freelancer invoicing a UAE company. Do I register for UAE VAT?
Generally no. Where you supply services to a VAT-registered UAE business, the reverse charge mechanism normally applies and your client accounts for the VAT themselves. Send a standard commercial invoice and note that reverse charge applies.
What is the difference between zero-rated and exempt in the UAE?
Zero-rated supplies are taxable at 0% — you issue tax invoices, file returns, and can recover input VAT on related costs. Exempt supplies sit outside the VAT system and block recovery of the associated input tax. Exports are typically zero-rated; bare land and certain financial services are exempt.
