Quick answer: A VAT-compliant tax invoice in the UAE must show the words "Tax Invoice," your name and 15-digit TRN, a unique invoice number and date, a description of what was sold, the net amount, the 5% VAT shown separately, and the total.
For B2B sales you also include the buyer's name and TRN. Consumer sales under AED 10,000 can use a simplified tax invoice.
Getting the tax invoice right is the most everyday piece of VAT configuration - you do it on every sale - and it's also where small errors quietly accumulate. This guide lays out exactly what must appear, when a simplified invoice is allowed, and how to avoid the mistakes the Federal Tax Authority (FTA) penalises. TajerGo, the UAE-built restaurant operating system that combines POS, inventory, purchasing, Khata, AI insights, and VAT configuration in one platform, produces compliant invoices automatically - but knowing the rules means you can check your own paperwork with confidence.
What does the FTA require on tax invoices?
Article 59 of the UAE VAT Executive Regulations sets the required contents of full and simplified tax invoices. The Federal Tax Authority’s tax-invoice guide explains that a full invoice identifies the supplier and registered recipient, includes their Tax Registration Numbers, uses a sequential or otherwise unique invoice number, records issue and supply dates where different, describes the supply, and shows line-level price, quantity, tax rate, and amounts in AED. It must also state the gross amount and tax payable. A simplified invoice is permitted when the recipient is not VAT registered, or when a VAT-registered recipient receives a supply whose consideration is AED 10,000 or less. The simplified document still needs the words “Tax Invoice,” supplier name, address and TRN, issue date, supply description, total consideration, and tax charged. Special cases, foreign currencies, rounding, and electronic-invoicing obligations can add requirements, so operators should check the current rule for the actual transaction.
What must a full UAE tax invoice include?
A full tax invoice has a defined set of mandatory fields under FTA rules:
| Field | What it is |
|---|---|
| "Tax Invoice" | The document must be clearly labelled as a tax invoice |
| Supplier details | Your business name and address |
| Your TRN | Your 15-digit Tax Registration Number |
| Invoice number | A unique sequential number |
| Date of issue | And the date of supply if different |
| Description | The goods/services supplied (your line items) |
| Net amount | The price before VAT |
| VAT amount | The 5% shown separately, not buried in the total |
| Total | The amount payable including VAT |
| Buyer details + TRN | Required when the buyer is a VAT-registered business (B2B) |
The non-negotiables that owners most often miss are the TRN, the separately-shown 5% VAT, and the buyer's TRN on B2B invoices.
When can I issue a simplified tax invoice?
A simplified tax invoice is the lighter format the UAE allows for everyday consumer transactions. You can use it when:
- The customer is not a VAT-registered business (a regular consumer), or
- The supply is under AED 10,000.
A simplified invoice still shows "Tax Invoice," your name and TRN, the date, a description, and the total with the tax amount - but it does not require the buyer's details and TRN. This is why a café receipt handed to a walk-in customer can be simplified, while a catering bill to a company at or above AED 10,000 must be a full tax invoice with the buyer's TRN.
| Situation | Invoice to issue |
|---|---|
| Walk-in consumer, any normal bill | Simplified tax invoice |
| Consumer supply under AED 10,000 | Simplified tax invoice |
| Sale to a VAT-registered business (B2B) | Full tax invoice (with buyer TRN) |
| Any supply at/above AED 10,000 | Full tax invoice |
How do I show VAT correctly on the invoice?
The 5% VAT must be broken out as its own line, not folded silently into the price. Show:
- The net (pre-VAT) amount,
- The 5% VAT amount on its own,
- The gross total the customer pays.
If your menu prices are VAT-inclusive, the invoice should still decompose the inclusive price into net + VAT so the tax is visible. Remember the arithmetic: VAT inside an inclusive price is the price divided by 1.05, then multiplied by 5% - not a flat 5% off the displayed figure.
What are the most common tax-invoice mistakes?
- Missing or wrong TRN - yours, or the buyer's on a B2B invoice.
- VAT not shown separately - burying the 5% in the total.
- Wrong invoice type - issuing a simplified invoice where a full one is required (B2B or ≥ AED 10,000).
- Non-unique invoice numbers - duplicates or gaps that break your audit trail.
- Inclusive-price miscalculation - decomposing the VAT incorrectly so the invoice doesn't reconcile.
Each of these is exactly the kind of thing the FTA's administrative penalties target, and each is avoidable with a system that fills the fields correctly every time.
How does this connect to e-invoicing?
A tax invoice that already carries the right fields - TRN, 5% VAT broken out, clean line items - is most of the way to being ready for UAE e-invoicing in the PINT AE format from 2027. Getting the everyday invoice right today is the groundwork that makes the e-invoicing transition a small step rather than a scramble.
How TajerGo helps
TajerGo supports configured seller and buyer TRN fields, line items and tax details in supported invoice workflows. Staff should confirm the appropriate invoice format, buyer details, tax configuration and final output before approval. The restaurant remains responsible for its tax setup; software configuration does not guarantee that every invoice is correct. PINT AE mapping, ASP connectivity and e-invoicing transmission require implementation and testing before use. Review current pricing and the supported scope for your proposed setup.
Frequently asked questions
What makes a tax invoice VAT-compliant in the UAE?
It must show the words "Tax Invoice," your name and 15-digit TRN, a unique invoice number and date, a description of the supply, the net amount, the 5% VAT shown separately, and the total. B2B invoices must also include the buyer's name and TRN.
When can a restaurant use a simplified tax invoice?
When the customer is not a VAT-registered business or the supply is under AED 10,000. A simplified invoice omits the buyer's details and TRN, which is why it suits everyday consumer receipts.
Do I have to show the VAT amount separately?
Yes. The 5% VAT must be shown as its own amount, not folded into the total. The invoice should show the net amount, the VAT, and the gross total.
What's the penalty for an incorrect tax invoice?
The Federal Tax Authority applies administrative penalties for invoicing failures such as a missing TRN or VAT not shown correctly. Issuing complete, correctly formatted invoices on every sale avoids this.
