A full UAE tax invoice (for supplies over AED 10,000) must include: the words “Tax Invoice”, supplier name/address/TRN, customer name/address/TRN, invoice date, sequential invoice number, description of goods or services, quantity, unit price (excluding VAT), discount (if any), subtotal, VAT rate, VAT amount, and gross total including VAT. A simplified tax invoice (for supplies of AED 10,000 or below, or retail/restaurant transactions) requires fewer fields. Penalties for non-compliant invoices start at AED 2,500 per invoice.
In the UAE, a tax invoice is a legal document — not just a payment request. Under the UAE VAT Law (Federal Decree-Law No. 8 of 2017) and its Executive Regulations, every VAT-registered business must issue invoices that meet strict FTA requirements. An invoice missing even one mandatory field is technically non-compliant and exposes your business to penalties.
This guide covers every mandatory field, the difference between full and simplified invoices, credit notes, e-invoicing, common mistakes, and the exact FTA penalties — so your business stays fully compliant. If you’re also handling VAT return filing or Corporate Tax alongside VAT, correct invoicing is the foundation of both.
Who Must Issue a Tax Invoice in the UAE?
Any business registered for VAT in the UAE (with a valid Tax Registration Number / TRN) must issue a tax invoice for every taxable supply it makes. This includes:
- Standard-rated supplies (5% VAT)
- Zero-rated supplies (0% VAT — e.g. exports, international transport, certain food items)
- Supplies to VAT-registered customers who need to reclaim input tax
Two Types of UAE Tax Invoice
The UAE VAT Executive Regulations create two invoice formats based on transaction value:
| Feature | Full Tax Invoice | Simplified Tax Invoice |
|---|---|---|
| When to use | Supplies exceeding AED 10,000 (incl. VAT) | Supplies of AED 10,000 or below, or retail / restaurant supplies regardless of value |
| Customer’s TRN required | ✓ If customer is VAT-registered | ✗ Not required |
| Unit prices required | ✓ Yes | ✗ Not required |
| VAT amount shown | ✓ Yes (per line and total) | ✓ Yes (total only) |
| Customer input VAT claim | ✓ Fully valid | ✓ Valid |
Full Tax Invoice — All 13 Required Fields
A full tax invoice is required for any supply exceeding AED 10,000 (inclusive of VAT). All 13 fields below are mandatory under Article 59 of the UAE VAT Executive Regulations:
| Description | Qty | Unit Price (AED) | Discount | VAT % | VAT (AED) | Total (AED) |
|---|---|---|---|---|---|---|
| Accounting Services — August 2026 | 1 | 750.00 | — | 5% | 37.50 | 787.50 |
| # | Mandatory Field | What to Include | Common Mistake |
|---|---|---|---|
| 1 | Invoice title | The words “Tax Invoice” — in English and Arabic if needed | Writing “Invoice” or “Receipt” only |
| 2 | Invoice date | Date the invoice is issued | Using the payment date instead of issue date |
| 3 | Sequential invoice number | Unique, sequential number (e.g. INV-2026-0001) | Repeating or non-sequential numbers |
| 4 | Supplier name | Registered trade name of the supplier | Using a nickname or brand instead of legal name |
| 5 | Supplier address | Registered business address in UAE | Using a PO Box only without full address |
| 6 | Supplier TRN | 15-digit Tax Registration Number | Missing or incorrect TRN |
| 7 | Customer name & address | Name and address of the recipient | Left blank for B2B transactions |
| 8 | Customer TRN | Customer’s TRN if they are VAT-registered | Not requesting customer’s TRN on B2B sales |
| 9 | Description of supply | Clear description of goods or services | Generic labels like “services rendered” |
| 10 | Quantity / volume | Number of units, hours, or measure supplied | Omitting quantity for service invoices |
| 11 | Unit price (excl. VAT) | Price per unit before VAT | Showing only the VAT-inclusive price |
| 12 | VAT rate & amount | The applicable VAT % (5%, 0%) and the AED VAT amount per line and in total | Showing only total VAT, not per line |
| 13 | Total amount incl. VAT | Gross payable amount in AED | Showing only the net amount |
Simplified Tax Invoice — 6 Required Fields
A simplified tax invoice is permitted for supplies of AED 10,000 or below (inclusive of VAT), and also for retail, restaurant, and similar consumer-facing transactions regardless of value. The 6 mandatory fields are:
- ✓ The words “Tax Invoice”
- ✓ Supplier’s name, address, and TRN
- ✓ Date of issue
- ✓ Description of goods or services
- ✓ Total VAT amount charged
- ✓ Total amount payable (inclusive of VAT)
Credit Notes & Debit Notes in the UAE
When a previously issued tax invoice needs to be adjusted — due to a return, discount, cancellation, or correction — you must issue a tax credit note (for reductions) or a tax debit note (for increases). These are legally required documents under UAE VAT law and must reference the original invoice.
Tax Credit Note — Required Fields
- The words “Tax Credit Note”
- Date of issue
- Sequential credit note number
- Supplier name, address, and TRN
- Customer name, address, and TRN
- Reference to the original tax invoice number
- Reason for the credit (return, discount, cancellation)
- Amount being credited (excl. VAT), VAT rate, VAT amount being reversed, and total credit amount
UAE E-Invoicing — What’s Coming
The UAE is rolling out a mandatory e-invoicing system (also called Digital Tax Administration or DTA). While timelines have been phased, the FTA has confirmed that e-invoicing will eventually be mandatory for all VAT-registered businesses.
Key points for UAE businesses to know now:
- E-invoices must carry the same mandatory fields as paper/PDF full tax invoices
- They must be issued through FTA-approved e-invoicing service providers
- QR codes on invoices are already required for simplified invoices under certain conditions
- Start preparing now: ensure your accounting system can generate FTA-compliant XML/PDF invoices

💬 Chat With a UAE VAT ExpertFTA Penalties for Incorrect or Missing Tax Invoices
The FTA takes invoicing non-compliance seriously. Penalties under Cabinet Decision No. 49 of 2021 (as amended):
Tax Invoice Record-Keeping Requirements
| Document Type | Minimum Retention Period | Format |
|---|---|---|
| Tax invoices issued (sales) | 5 years (VAT law); 7 years if also used for Corporate Tax | Paper or electronic — FTA-accessible |
| Tax invoices received (purchases) | 5 years (VAT) / 7 years (CT) | Must be legible and accessible |
| Credit and debit notes | 5 years | Linked to original invoice |
| VAT returns and workings | 5 years | Electronic on EmaraTax + supporting schedules |
| Import / export documents | 5 years | Linked to zero-rated supply invoices |
Common UAE Tax Invoice Mistakes — and How to Fix Them
| Mistake | Risk | Fix |
|---|---|---|
| Issuing invoice as “Invoice” not “Tax Invoice” | AED 2,500 penalty per invoice; customer cannot reclaim VAT | Update invoice template — title must say “Tax Invoice” |
| Missing supplier TRN or wrong TRN | Invoice invalid for VAT purposes; customer input VAT disallowed | Verify your TRN on tax.gov.ae and add to all templates |
| Not collecting customer TRN for B2B invoices | FTA may disallow customer’s input VAT claim in audit | Request TRN from all business customers before issuing invoice |
| Non-sequential invoice numbers | FTA audit flag — suggests undeclared supplies | Use accounting software with auto-sequential numbering |
| Showing only VAT-inclusive price, not unit price ex-VAT | Non-compliant full tax invoice | Update template to show: Unit Price, VAT %, VAT Amount, Gross Total |
| Issuing in foreign currency without AED conversion | VAT amount must be expressed in AED | Show original currency amounts plus AED equivalent using UAE Central Bank rate on invoice date |
| Not issuing credit notes for returns/cancellations | Output VAT overstated; FTA treats original invoice as final | Issue a credit note within the same or next VAT period; both parties adjust their returns |
