What is a tax invoice in the UAE?
A tax invoice is a document that VAT-registered businesses must issue for any taxable supply to recognize a revenue transaction. A tax invoice should be issued by the seller to the buyer within 14 days of the date of supply. The copy of the invoice must be stored for audit purposes:- for 5 years in general
- for 15 years, in case of transactions related to real estate
Why is it important to store properly formatted tax invoices?
These tax invoice records serve as the basis of the financial documentation for your company and ensure tax compliance with UAE VAT regulations:- When properly issued to your buyers, they help you avoid a 2,500 AED administrative fine for each case of an unissued or incorrectly formatted tax invoice
- Once received from your suppliers, they serve as proof of the purchase transaction to claim input VAT
- You can still use them after registering to claim input VAT. Purchases of services can be claimed within a 5-year period from the date of purchase, while goods can be claimed for their unused portion. For example, for capital assets, this would be the non-depreciated portion.
- VAT-compliant tax invoices also ensure that your expenses will be deductible for corporate tax (CT) purposes as well. More on that point below
CT-compliant purchase invoices
Although CT regulation doesn’t strictly define the required invoice fields (unlike VAT), you must still keep adequate records to substantiate income/expenses and file correctly; the record-keeping period is 7 years after the end of the relevant Tax Period. So, in our practice, we rigorously check that the following fields are listed on the invoices that our clients receive, so that their expenses are deductible for CT purposes:| Field | Requirement |
|---|---|
| Issuing company name | Must be valid and verifiable via FTA |
| Recipient name | Must match your registered business details |
| Invoice date | Must reflect the actual transaction date |
| Unique invoice number | Enables traceability and record tracking |
| Description of goods or services | Must be specific and clear, not generic |
| Currency and amount | Used to calculate the taxable base |
What if the purchase invoice doesn’t contain one of the fields above?
You might lose on two fronts:- The expense will not be recognized for CT deduction (9% of the purchase amount) because the transaction records are not sufficient
- You will not be able to claim input VAT (5% of the purchase amount) because these fields are required for VAT compliance of the invoice as well. As you will see in the next section, VAT invoice standards in the UAE are stricter than those for CT and require more fields to be present in the invoice
VAT invoice format: full tax invoice vs simplified invoice
There are two types of VAT invoice formats: full tax invoice and simplified tax invoice. Let’s take a closer look at them. A full (standard) tax invoice is a detailed document that a seller issues to a buyer for a taxable supply to recognize a revenue transaction. You must issue a full tax invoice if at least one of the following FTA conditions is met:- The recipient is VAT-registered.
- The amount of the supplies exceeds AED 10,000.
- Transactions valued at AED 10,000 or less
- Sales to customers who are not VAT-registered
Federal Tax Authority (FTA) requirements for a full (standard) tax invoice
- The words “Tax Invoice” clearly displayed on the invoice
- Issuing company (supplier) name with address and Tax Registration Number
- Recipient company (customer) name with address and Tax Registration Number
- Unique invoice number

- The date of supply, if different from the date of issuing the tax invoice
- A description of the goods or services supplied
- For each good or service: the unit price, the quantity or volume supplied, the rate of tax, and the amount payable in AED
- The amount of any discount offered

How to calculate VAT?
Here is a good example of how to calculate VAT. For the supply of goods/services for AED 20,000 at a 5% VAT rate:- Net amount: AED 20,000
- Discount applied (10% rate): AED 2,000
- VAT amount (5% rate): AED 1,000 = 18,000 * 5%
- Gross amount: AED 21,000.
Common mistakes and penalties
Non-compliance with FTA tax invoice requirements may result in large fines. Let’s break down the most common mistakes, what they can cost you, and how to avoid them.
Table with the most common FTA violations and penalties

Can I use tax invoice templates for my UAE business?

How to handle tax invoices in foreign currencies?
When issuing tax invoices in a currency other than AED, you are required to convert the taxable amount and the VAT amount into dirhams using the official exchange rate applied as published by the UAE Central Bank on the exact date of supply. The exchange rate must be clearly displayed on the invoice.
What is the difference between VAT Return filing and Tax Invoice?
A VAT Return is the periodic summary you file with the FTA showing total VAT due or refundable for the period, whereas a tax invoice serves as the legal proof for each taxable supply and the VAT charged.
For how long must invoices be stored? What happens if a company does not keep Tax Invoices?
In the UAE, tax invoices must be stored for a minimum of 5 years and a maximum of 15 years for real estate records. If a company fails to keep its tax invoices, the Federal Tax Authority (FTA) may impose administrative penalties and disallow input VAT recovery, which can increase the business’s overall tax liability.
How to calculate VAT?
To calculate VAT in the UAE, multiply the taxable amount (the value of goods or services) by the applicable VAT rate, currently 5%. For example, if the taxable value is AED 1,000, VAT = 1,000 × 5% = AED 50. The total invoice amount payable would then be AED 1,050.
Can I issue a handwritten tax invoice in the UAE?
Yes, handwritten tax invoices are legally allowed in the UAE as long as they contain all the mandatory details required by the FTA such as TRN, invoice date, description of goods/services, VAT amount, and total payable. However, most businesses use electronic invoicing systems because they reduce errors and make compliance easier.
