Issuing an invoice in the UAE may seem straightforward. Add the customer details, describe what you sold, calculate VAT and send the bill. For a VAT-registered business, though, the invoice has to meet specific Federal Tax Authority requirements.
A missing TRN, incorrect VAT figure or wrong invoice type can create problems when you prepare your VAT return or face an FTA review. The customer may also need a proper tax invoice to support their VAT records.
The main UAE tax invoice format requirements come from Article 59 of the VAT Executive Regulation. The rules cover full tax invoices, simplified invoices, foreign-currency transactions and cases where the recipient accounts for VAT.
Here is what your invoice should contain and what businesses need to check.
What Is a Tax Invoice in the UAE?
A tax invoice is a document issued by a VAT registrant for a taxable supply of goods or services. It records the transaction and the VAT charged. Your standard commercial invoice therefore cannot simply show a final amount and call it VAT compliant. It needs the details required under UAE VAT law.
The words "Tax Invoice" should also appear clearly on the document.
If your business has recently registered for VAT, make sure you are using the correct Tax Registration Number rather than confusing it with another company identifier. Nexture's guide to the company registration number in the UAE explains the difference between business registration details and the tax information businesses use for compliance.

Mandatory Details on a Full UAE Tax Invoice
Article 59 sets out the information required on a standard full tax invoice. Your invoice should contain:
The words "Tax Invoice"
Display them clearly so there is no uncertainty about the type of document.Supplier details
Include the supplier's name, address and Tax Registration Number.Customer details
Where the recipient is VAT registered, include their name, address and TRN.A unique invoice number
Use a sequential number or another unique numbering system that identifies the invoice and its position within the invoice sequence.Invoice issue date
State the date on which you issued the invoice.Date of supply
Include this separately when it differs from the invoice date.Description of the goods or services
Avoid descriptions such as "services" or "items" where a clearer description can be provided.Price and quantity information
For each good or service, show the unit price, quantity or volume, VAT rate and amount payable in AED.Discounts
State any discount applied to the transaction.Gross amount payable
Show the gross amount in UAE dirhams.VAT payable
The VAT amount must be stated in AED.Reverse-charge statement where applicable
If the recipient must account for VAT, the invoice should state this and refer to the relevant VAT provision.
The FTA also publishes a useful tax invoice checklist that businesses can use when reviewing their invoice templates.
Example of a UAE Tax Invoice Format
A simple full tax invoice could look like this:
Field | Example |
Document | TAX INVOICE |
Supplier | ABC Trading LLC |
Address | Dubai, UAE |
Supplier TRN | 100123456789012 |
Customer | XYZ Services LLC |
Customer TRN | 100987654321012 |
Invoice number | INV-2026-0048 |
Invoice date | 15 August 2026 |
Supply date | 15 August 2026 |
Description | Business consultancy services |
Amount before VAT | AED 10,000 |
VAT rate | 5% |
VAT | AED 500 |
Total payable | AED 10,500 |
Your actual layout can look different. The FTA requirement centres on the information contained in the invoice rather than a particular graphic design.
Keeping the same structure throughout your accounting system also makes reconciliation easier. If the FTA later reviews your transactions, invoices should be traceable to the accounting records and VAT returns. Nexture's guide to preparing for a tax audit in the UAE explains the records that may be checked during an audit.
Full Tax Invoice vs Simplified Tax Invoice
Not every transaction needs the full format.
A VAT registrant may issue a simplified tax invoice where:
The recipient is not registered for VAT, or
The recipient is VAT registered but the consideration for the supply does not exceed AED 10,000
The 2025 amendments of the VAT Executive Regulation also clarify that a simplified invoice cannot be used where the reverse charge mechanism applies.
Mandatory details on a simplified invoice
A simplified tax invoice needs:
The words "Tax Invoice"
Supplier's name, address and TRN
Date of issue
Description of the goods or services
Total consideration in AED
VAT charged in AED
You can still issue a full invoice even where a simplified invoice is permitted.
When Must a Full Tax Invoice Be Issued?
The general deadline is within 14 days from the date of supply. Article 67 of the UAE VAT Decree-Law sets this timeframe.
Do not automatically use the date when payment reaches your bank account. VAT has specific date-of-supply rules and the correct tax point can depend on the transaction. Late or incorrect invoicing can also affect the figures eventually reported in your VAT return.
What If You Invoice in USD, EUR or Another Currency?
You can conduct transactions in another currency, but UAE VAT reporting still requires AED figures. Where the supply is denominated in a foreign currency, the VAT amount must be converted into UAE dirhams using the exchange rate approved by the Central Bank of the UAE on the relevant date of supply.
The invoice should also show the exchange rate applied where conversion is required.
For example:
Invoice value: USD 10,000
VAT: USD 500
Applicable USD/AED rate: 3.6725
VAT stated in AED: AED 1,836.25
Your accounting records should use the same conversion basis.
Common UAE Tax Invoice Mistakes
Most invoice problems come from routine processing rather than complicated tax questions.
Using the wrong TRN
A typo in a 15-digit TRN can make your records inconsistent. Verify both supplier and customer details before issuing high-value B2B invoices.
Leaving out the date of supply
The invoice date and supply date are not always the same. Where they differ, both should appear.
Showing VAT only in a foreign currency
Even if your customer pays in dollars, euros or pounds, VAT still needs to be stated in AED under the UAE rules.
Using a simplified invoice where reverse charge applies
The amended Article 59 specifically prevents this.
Creating duplicate invoice numbers
Your numbering system should identify each invoice clearly and preserve its order.
Deleting an invoice after a correction
If a transaction changes after invoicing, the correct VAT treatment may require a tax credit note or another proper adjustment. Do not simply remove the original transaction from your accounting records.

FTA Penalties for Tax Invoice Violations
Administrative penalties should not be treated as an afterthought.
Cabinet Decision No. 129 of 2025 became effective on 14 April 2026 and amended several UAE tax penalties. The current framework includes an AED 2,500 penalty per detected case for failure to issue a tax invoice within the legally specified requirements and timeframe.
The safest approach is simple: configure the invoice template correctly before you start issuing invoices rather than fixing hundreds of documents later.
How Long Should You Keep VAT Invoices?
VAT-registered businesses should retain tax invoices issued and received for at least five years.
The FTA VAT invoice retention guidance specifically confirms the minimum five-year retention period for VAT invoices. Records relating to real estate can be subject to longer retention requirements. Keep electronic records searchable and properly backed up. An invoice stored somewhere in an old email account is far less useful during a tax review than a document linked directly to the relevant accounting entry.
How UAE eInvoicing Changes the Invoice Process
UAE invoicing is moving towards a structured electronic system.
The pilot programme began on 1 July 2026 and businesses can also adopt qualifying electronic invoicing voluntarily. Mandatory implementation begins in phases from 2027.
Businesses with annual revenue of AED 50 million or more are currently required to implement the system by 1 January 2027. Their deadline to appoint an Accredited Service Provider was extended to 30 October 2026.
An important distinction is that a PDF sent by email is not an electronic invoice under the new UAE system. The Ministry of Finance defines an eInvoice as structured invoice data exchanged electronically through the prescribed system.
Businesses preparing their accounting software should follow the official UAE Ministry of Finance eInvoicing portal because technical requirements and implementation guidance can continue to develop.
Conclusion
A compliant UAE tax invoice format starts with getting a few basic details right every time: supplier and customer information, TRNs, invoice numbering, supply dates, transaction details and VAT figures in AED.
The simplified format can reduce paperwork for eligible transactions, but the AED 10,000 threshold and reverse-charge restriction need to be checked first. Timing matters too. Full tax invoices generally need to be issued within 14 days, while simplified invoices must be issued on the date of supply.
Review your invoice template once, configure your accounting software properly and periodically check it against current FTA rules. That small routine can prevent much larger VAT problems later.
