UAE VAT guide
What makes a valid UAE tax invoice
The mandatory fields, the difference between a full and a simplified tax invoice, the AED 10,000 threshold, and the 14-day issuing rule.
A tax invoice is the document that lets your customer reclaim their input VAT — and lets you prove your output VAT. If it's missing mandatory fields, it isn't a valid tax invoice, and the VAT on it can be challenged. The UAE rules (Article 59 of the Executive Regulation) set out exactly what a compliant invoice must contain.
Full tax invoice — mandatory fields
- The words "Tax Invoice" clearly shown.
- The supplier's name, address and TRN.
- The recipient's name, address and TRN, where the recipient is registered.
- A sequential or unique invoice number.
- The date of issue, and the date of supply if different.
- A description of the goods or services.
- For each line: unit price, quantity, tax rate and amount payable in AED.
- Any discount offered.
- The total excluding tax, the tax amount payable in AED, and the gross total.
- Where the reverse charge applies, a statement that the recipient must account for the VAT.
Simplified tax invoice
A simplified tax invoice is a shorter format allowed when the customer is not registered for VAT, or the supply does not exceed AED 10,000. It must still show:
- The words "Tax Invoice".
- The supplier's name, address and TRN.
- The date of issue.
- A description of the goods or services.
- The total consideration and the tax amount charged.
The AED 10,000 threshold
The threshold decides the format: a taxable supply above AED 10,000 requires a full tax invoice; at or below it (and where the simplified conditions are met) a simplified invoice is acceptable. When in doubt, a full invoice is always acceptable.
The 14-day rule
A tax invoice must be issued within 14 days of the date of supply, subject to defined exceptions. Late issuance is a compliance failure even if the VAT is otherwise correct.
What e-invoicing changes
Once your business is integrated into the UAE e-invoicing system, the simplified format is no longer permitted — every invoice must carry the full data set in the required structured format, regardless of value or customer type. If you rely on simplified invoices today, plan for that change.
Common mistakes to avoid
- No "Tax Invoice" wording or a missing/blurred TRN — both invalidate the invoice.
- Using a simplified invoice above AED 10,000, or for a registered customer who needs a full one.
- No AED amounts — VAT and totals must be shown in dirhams even if billed in another currency.
- Issuing later than 14 days after the supply.
Frequently asked questions
What must a full UAE tax invoice contain?
The words "Tax Invoice"; the supplier’s name, address and TRN; the recipient’s name, address and TRN (if registered); a unique sequential invoice number; the issue date and the date of supply if different; a description of goods/services; per line the unit price, quantity, tax rate and amount in AED; any discount; the total before tax, the tax amount, and the gross total in AED.
When can I issue a simplified tax invoice?
When the customer is not VAT-registered, or the supply does not exceed AED 10,000. A simplified invoice needs the words "Tax Invoice", the supplier’s name/address/TRN, the date, a description, and the total consideration with the tax amount.
What is the AED 10,000 threshold?
Any taxable supply above AED 10,000 requires a full tax invoice. At or below AED 10,000 (and where allowed), a simplified tax invoice can be used.
How quickly must a tax invoice be issued?
Within 14 days of the date of supply, subject to defined exceptions.
Does a reverse-charge purchase need anything special on the invoice?
Where the reverse charge applies, the tax invoice should state that the recipient must account for the VAT. For imported services from a foreign supplier, you self-account for the VAT regardless of what their invoice says.
