Tax invoice: what it means in UAE tax.
The meaning of tax invoice under UAE VAT law: how it works, a worked example in AED, common mistakes and the legal references.
A tax invoice is the document a UAE VAT registrant must issue for a taxable supply, with set details, normally within 14 days of supply.
What tax invoice means
Also called: VAT invoice.
A tax invoice is the written or electronic document that records a taxable supply and its VAT details. A VAT registered business that makes a taxable supply must issue one and deliver it to the customer. For a deemed supply with no customer, the business keeps it in its own records.
The Executive Regulation lists what a full tax invoice must show, including the words "Tax Invoice", the supplier's name, address and tax registration number, the customer's details where the customer is registered, a unique sequential number, dates, a description, unit prices, the VAT rate and the VAT amount in dirhams.
For the customer, the tax invoice is the key evidence for deducting input tax. For the supplier, issuing it late or without the required details is a penalty offence. As the UAE moves to electronic invoicing, a registrant within scope must issue tax invoices as structured electronic invoices through the approved system.
How it works
- Issue the tax invoice within 14 days of the date of supply, unless a simplified tax invoice or summary invoice rule applies.
- Show all amounts payable, and the VAT, in AED. Where the price is in another currency, state the exchange rate applied; the law points to the Central Bank rate on the date of supply.
- Where the customer must account for VAT under the reverse charge, the invoice must say so and refer to the relevant provision of the VAT law.
- A customer that is a registrant may raise the invoice for the supplier if both agree in writing and it is marked "Tax Invoice raised by buyer".
- Since 14 April 2026, failing to issue a tax invoice within the legal period carries a penalty of AED 2,500 for each detected case.
Worked example
An IT reseller in Sharjah supplies 10 laptops to a registered accounting firm and gives a discount on the order.
| 10 laptops at 3,200 each | AED 32,000 |
| Discount | AED 2,000 |
| Value before VAT | AED 30,000 |
| VAT at 5% | AED 1,500 |
| Total payable | AED 31,500 |
Each of these lines, plus the unit price, quantity and VAT rate, must appear on a full tax invoice.
Common mistakes
- Leaving out the customer's tax registration number when the customer is registered.
- Issuing a quotation or proforma and treating it as the tax invoice, or issuing the real invoice after 14 days.
- Showing VAT only in a foreign currency without the AED amount.
The law
- Federal Decree-Law No. 8 of 2017 on Value Added Tax, Article 1 (definition of Tax Invoice), Articles 65, 67 and 69
- Cabinet Decision No. 52 of 2017 (Executive Regulation of the VAT law), Article 59, Clauses 1, 9 and 13
- Cabinet Decision No. 40 of 2017 on administrative penalties, as amended by Cabinet Decision No. 129 of 2025, Table No. 3, items 4 and 6
Frequently asked questions
Do I need a tax invoice for a zero-rated supply?
The Executive Regulation says a registrant need not issue a tax invoice for a wholly zero-rated supply if sufficient records exist to establish the details of the supply. Many businesses still issue one for clarity.
Can a tax invoice be sent by email as a PDF?
Electronic tax invoices are allowed if the business can store them securely and guarantee their origin and integrity. Businesses brought into the electronic invoicing system must use structured electronic invoices instead.
