UAE tax invoice requirements: what a VAT invoice must include
If you run a business or freelance in the United Arab Emirates, the type of invoice you issue depends on whether you are registered for VAT. This guide explains what a full tax invoice must contain, when a simplified tax invoice is enough, and what to put on your invoices if you are not registered. It is a practical summary, not tax advice, so check the Federal Tax Authority's guidance or an accountant for your situation.

Do you need to be VAT registered?
VAT in the UAE is charged at a standard rate of 5%. Registration is mandatory when your taxable supplies and imports over the previous 12 months exceed AED 375,000, or are expected to exceed it in the next 30 days. Businesses above AED 187,500 can choose to register voluntarily.
Many new freelancers and small businesses are below these thresholds and are not registered. If that is you, you must not charge VAT and must not call your document a tax invoice. A normal invoice is the right document.
What a full tax invoice must show
Once you are registered, invoices for taxable supplies to VAT-registered customers must be tax invoices. A full tax invoice must include:
- The words Tax Invoice clearly displayed.
- Your name, address and Tax Registration Number (TRN).
- The customer's name and address, and their TRN if they are registered.
- A sequential invoice number that uniquely identifies the invoice.
- The date of issue, and the date of supply if it is different.
- A description of the goods or services supplied.
- For each item: the quantity, unit price, VAT rate and amount payable excluding VAT.
- Any discount offered.
- The total excluding VAT, the VAT amount in AED, and the total payable including VAT.
- If the invoice is in a foreign currency: the VAT amount converted into AED and the exchange rate used.
- Where the customer must account for the VAT under the reverse charge mechanism, a statement saying so.
Simplified tax invoices
In some cases a simplified tax invoice is allowed: generally when the customer is not VAT registered, or when the value of the supply does not exceed AED 10,000. A simplified tax invoice needs fewer details, such as the words Tax Invoice, your name, address and TRN, an invoice number, the date, a description of the supply, and the total including VAT and the VAT amount.
If you are unsure which one applies, issue a full tax invoice. It is always acceptable where a simplified one would be.
Timing and record keeping
A tax invoice should normally be issued within 14 days of the date of supply. Keep copies of every invoice you issue and receive, along with your other accounting records, for at least five years, or longer where the rules for your situation require it, such as for real estate.
Never reuse or skip invoice numbers. If an invoice is wrong after it has been issued, the usual fix for a registered business is a tax credit note, not editing or deleting the original.
Foreign currency invoices
You can invoice in US dollars, euros or any other currency, which is common when working with international clients. If you are VAT registered, the invoice must still show the VAT amount in AED and the exchange rate you used. Use the UAE Central Bank's published rate for the date of supply, or another method the authority accepts, and apply it consistently.
Electronic invoicing is coming
The UAE has announced a mandatory e-invoicing system that is being introduced in phases, starting with larger businesses. Under it, invoices are exchanged electronically in a structured format through accredited service providers instead of as PDFs. If you are VAT registered, watch the Ministry of Finance and Federal Tax Authority announcements for the dates that apply to your business size.
If you are not VAT registered
Most early-stage freelancers fall into this group. Your invoice should be a clear, professional invoice without VAT:
- Title it Invoice, not Tax Invoice.
- Do not add VAT or show a TRN you do not have.
- Include your name or trade name, contact details and, if you have one, your trade licence or freelance permit number.
- Include the client's details, a unique invoice number, the date, line items, the total and payment details such as your IBAN.
- Keep a running total of your income during the year so you notice when you approach the registration threshold.
Using Zonlet
Zonlet's free invoice generator produces a standard invoice titled Invoice, with AED and other currencies, line items, an optional tax percentage, a due date and notes. That makes it a good fit for freelancers and small businesses that are not VAT registered: add your licence or permit number and your bank details in the notes. If you are VAT registered, check that your invoice includes every item in the tax invoice list above, including the words Tax Invoice and your TRN, before using it for VAT purposes.
