Quick answer
A standard UAE tax invoice must clearly state “Tax Invoice” and include the supplier’s name, address and TRN; the registered customer’s name, address and TRN; a sequential or uniquely traceable invoice number; issue date; supply date where different; a description of the goods or services; quantity, unit price, VAT rate and values in AED; discounts; gross amount; VAT amount; and additional reverse-charge wording where applicable. It generally must be issued within 14 days from the date of supply.

Who Must Issue a UAE Tax Invoice?
A VAT registrant making a taxable supply generally must issue an original tax invoice and deliver it to the customer. A registrant making a deemed supply should also issue and retain the relevant invoice in accordance with the VAT rules.
Tax invoices are generally relevant to standard-rated sales, taxable advances, recurring taxable supplies, deemed supplies and additional VAT identified after an original invoice.
A tax invoice may not be required for a wholly zero-rated supply where sufficient records exist to establish the transaction. This exception should be applied only after confirming the legal conditions and evidence.
Only a VAT registrant should charge UAE VAT
A person who states VAT as payable on a document can become liable to pay that amount to the FTA even where the tax was not correctly due.
Mandatory Details on a Standard UAE Tax Invoice
Article 59 of the VAT Executive Regulation requires the following particulars:
- The words “Tax Invoice” clearly displayed
- Supplier’s registered name, address and TRN
- Registered customer’s name, address and TRN
- A sequential or uniquely traceable invoice number
- Invoice issue date
- Date of supply where different
- Description of goods or services
- Unit price, quantity or volume, VAT rate and payable amount for each item in AED
- Any discount offered
- Gross amount payable in AED
- VAT amount payable in AED and the exchange rate where conversion applies
- Reverse-charge statement and legal reference where the customer accounts for VAT
A logo, purchase-order number, payment terms and bank details may be useful commercially, but they do not replace the statutory details.
When Can a Simplified Tax Invoice Be Used?
A simplified invoice may be issued where the customer is not VAT registered, regardless of value, or where the customer is registered and consideration does not exceed AED 10,000.
It must show:
- The words “Tax Invoice”
- Supplier name, address and TRN
- Issue date
- Description of goods or services
- Total consideration and VAT amount charged
A standard invoice can still be safer commercially
Even when simplified invoicing is allowed, a standard format can better support customer procurement, input VAT review and contract reconciliation.
Date of Supply and the 14-Day Rule
A registrant generally must issue the tax invoice within 14 days from the date of supply. The date of supply can be triggered by delivery, service completion, payment, invoice issuance, a contractual milestone or a recurring-supply rule.
Where the issue date and supply date differ, show both. Delaying the invoice does not necessarily delay the VAT liability.
Example
Service completed on 4 August 2026 and invoice issued on 10 August 2026: both dates should appear, and the invoice is within the general 14-day period.
Invoice compliance should be tested against the contract, delivery record, VAT code, customer status and ledger—not only against the visual template.
Foreign Currency, AED Conversion and Rounding
A commercial invoice can be denominated in another currency, but required VAT values must be expressed in AED. Convert using the Central Bank-approved exchange rate at the date of supply and show the VAT amount in AED and the exchange rate applied.
The system should apply the prescribed rounding method consistently across line items and invoice totals. Review calculation logic using the UAE VAT rate guide and worked VAT examples.
Special UAE VAT Invoice Situations
Summary invoices
Multiple supplies to the same customer can be included on a summary tax invoice issued within the same calendar month, subject to the conditions.
Buyer-created invoices
A VAT-registered customer can issue the invoice on behalf of the supplier where both agree in writing, the supplier does not issue another invoice and the document states “Tax Invoice raised by buyer.”
Profit-margin scheme
The invoice should state that VAT was charged by reference to the profit margin and should not disclose the VAT amount in the ordinary way.
Electronic invoices
Electronic tax invoices are permitted where a secure copy can be retained and authenticity of origin and integrity of content are guaranteed.
Correcting an Invoice
Do not simply delete or overwrite a reported invoice. If VAT was understated, issue an additional tax invoice for the additional amount. If VAT or consideration was overstated or reduced, issue a tax credit note that identifies the original supply, original and corrected values, the difference, related VAT and the reason.

Why Supplier Invoices Matter for Input VAT Recovery
A customer claiming input VAT generally must receive and retain a valid tax invoice and satisfy the other recovery conditions. Check the supplier’s VAT status and TRN, customer legal entity, business use, VAT treatment, date of supply, payment intention and whether the tax is otherwise recoverable.
Review the input VAT versus output VAT guide.
Records and Audit Trail
Retain issued and received invoices, credit notes, contracts, purchase orders, delivery evidence, TRN verification, exchange-rate support, export and import records, invoice sequence logs and VAT-return reconciliations.
Ordinary VAT records are generally retained for at least five years, with longer periods applying to certain real-estate and capital-asset records. Do not automatically substitute the seven-year Corporate Tax record period for VAT.
For monthly controls, read the bookkeeping for VAT guide.
VAT Tax Invoices Versus UAE Electronic Invoices
A PDF tax invoice can comply with current VAT content rules, but a PDF or email attachment is not automatically an eInvoice under the UAE Electronic Invoicing System. E-invoicing requires structured data, exchange through Accredited Service Providers, technical validation and electronic reporting.
Technical validation does not prove commercial correctness
An eInvoice can pass system validation while the quantity, delivery, price, milestone or VAT treatment remains incorrect.
VAT Invoice Compliance Checklist
1. Verify registration: supplier VAT status and TRN.
2. Confirm customer: legal entity and VAT status.
3. Select format: standard or simplified.
4. Determine date of supply: do not rely only on billing date.
5. Confirm VAT treatment: 5%, 0%, exempt, outside scope or reverse charge.
6. Check values: quantity, unit price, discount, VAT and gross amount.
7. Convert currency: show required values in AED.
8. Reconcile: match invoice and credit-note registers to the VAT return.
