A valid UAE VAT invoice needs your TRN, the invoice date and a sequential number, a description and VAT rate per line item, and the total including VAT. The FTA also has specific rules for simplified invoices under a certain value.
The UAE's Federal Tax Authority (FTA) sets specific requirements for what counts as a valid VAT invoice. Missing a required field doesn't just look unprofessional — it can mean the invoice isn't valid for VAT recovery purposes on the buyer's side.
What a standard VAT invoice needs
- The words "Tax Invoice" clearly shown
- Your business name, address, and Tax Registration Number (TRN)
- The buyer's name, address, and TRN (for B2B invoices)
- A sequential invoice number and the date of issue
- A description of the goods or services, quantity, and unit price per line
- The VAT rate applied (standard 5%, zero-rated, or exempt) and the VAT amount per line
- The total amount payable, including VAT
Simplified invoices
For lower-value transactions (a threshold set by the FTA), a simplified invoice is allowed, which drops some of the buyer-detail requirements. This is common in retail settings where itemizing the buyer's full registration details on every small sale isn't practical.
Standard, zero-rated, and exempt
Not everything is taxed at the standard 5% rate. Some goods and services are zero-rated (taxed at 0%, but still VAT-relevant), and others are exempt entirely (outside the VAT system). Getting this classification wrong per item — rather than defaulting everything to standard-rated — is one of the more common invoicing errors we see.
Keeping records
The FTA expects VAT records to be retained for a set number of years, in a form that can be produced on request. Digital invoicing that keeps a running, exportable record does this by default; a folder of printed paper invoices makes it a manual project each time.
StashBill's compliance engine applies these FTA field requirements automatically — see the full UAE VAT invoicing breakdown.Frequently asked
Do I need a TRN to issue VAT invoices?
Yes — a business must be VAT-registered and have a valid TRN to issue tax invoices; unregistered businesses cannot charge VAT.
What's the difference between zero-rated and exempt?
Zero-rated supplies are taxable at 0% and are still part of the VAT system (and may allow input VAT recovery); exempt supplies fall outside the VAT system entirely.
