Frequently Asked Questions
What is the difference between a full tax invoice and a simplified tax invoice in the UAE?
A full tax invoice is required when the supply value exceeds AED 10,000 and the recipient is a VAT-registered business. It must include the customer's name, address, and TRN. A simplified tax invoice applies to supplies under AED 10,000 or retail transactions with end consumers, and does not require the customer's TRN or address.
Does a UAE tax invoice have to show the VAT amount in AED if the invoice is in a foreign currency?
Yes. The Federal Tax Authority requires the VAT amount to be expressed in UAE Dirhams even when the invoice is denominated in a foreign currency. The AED equivalent must be calculated using the Central Bank rate on the date of supply, and the conversion rate used should be documented.
What happens if a supplier issues an invoice without the customer's TRN?
Without the customer's TRN on a full tax invoice, the recipient cannot recover input VAT on that purchase. The FTA treats the missing TRN as a non-compliant invoice, and the issuing business may face a fixed penalty of AED 1,000 per non-compliant invoice, up to AED 55,000 per audit cycle.
How long must UAE businesses keep tax invoices?
The standard minimum retention period is five years from the end of the relevant tax period. For real estate transactions, records must be kept for fifteen years. Records can be held digitally or on paper, but must be retrievable and available for FTA inspection on request.
Does a credit note need to meet the same requirements as a tax invoice?
Yes. UAE credit notes and debit notes are treated as tax documents in their own right. They must reference the original invoice number and date, state the reason for the adjustment, and show the corrected VAT amount. Both the supplier and recipient must adjust their VAT returns in the period the credit note is issued.
Topic Summary
The Words 'Tax Invoice' Must Appear
Every UAE tax invoice must include the exact words 'Tax Invoice' on the document. Missing this label is one of the most common compliance errors and is treated as a non-compliant invoice by the Federal Tax Authority.
Supplier and Customer TRN Are Both Required
A full tax invoice must show the 15-digit Tax Registration Number of both the supplier and the customer. Without the customer's TRN, the recipient cannot recover input VAT — making this field commercially critical, not just a formality.
Two Dates Must Appear: Invoice and Supply
The invoice date and the supply date are separate requirements and can differ. Both must appear on a full tax invoice. Your VAT liability is determined by the date of supply, not when the invoice is issued.
VAT Amount Must Be Expressed in AED
Even if your invoice is denominated in a foreign currency, the VAT amount must be stated in UAE Dirhams using the Central Bank rate on the date of supply. This catches many cross-border businesses off guard.
Sequential Numbering Is a Legal Requirement
Each invoice must carry a unique, sequential number that creates an auditable trail. Gaps in numbering or reused numbers are treated as red flags during FTA audits and can trigger penalties.
Simplified Invoices Have Different Rules
For supplies under AED 10,000 to end consumers, a simplified tax invoice is permitted — it does not require the customer's TRN or address. However, using a simplified format for B2B transactions above that threshold is a compliance error.
Penalties Run Up to AED 55,000 Per Audit Cycle
Failing to issue a tax invoice carries a fixed penalty of AED 5,000 per instance. Issuing an invoice without the required fields costs AED 1,000 per non-compliant invoice, capped at AED 55,000 — separate from any VAT assessments that may follow.
UAE Tax Invoice Requirements: What Must Appear on Every Invoice
A tax invoice is not just a bill. It is the document that proves a taxable supply happened. It is also what allows your customer to recover the VAT they paid you.
Get a field wrong and the consequences land on both sides. You risk a penalty. Your customer risks an argument with the Federal Tax Authority about their recovery. This guide sets out what must appear, when a shorter format is allowed, and what changes as electronic invoicing arrives. It is general information only, not tax advice. Confirm the current requirements before redesigning your templates.

What Counts as a Tax Invoice
The heading matters. An invoice must display the words "Tax Invoice" clearly. That separates it from a quote, a proforma, or a statement, none of which support VAT recovery.
Every VAT registered business must issue one for a taxable supply. The obligation sits with the supplier. A customer chasing you for a compliant invoice is not being difficult, since their recovery position depends on it.
Fields Required on a Full Tax Invoice
Article 59 sets out twelve particulars. The table below groups them into what they cover.
Full Tax Invoice Compared With Simplified
| Field | Full invoice | Simplified invoice |
|---|---|---|
| The words "Tax Invoice" | Required | Required |
| Supplier name, address, TRN | Required | Required |
| Recipient name, address, TRN | Required where registered | Not required |
| Unique or sequential number | Required | Not required |
| Date of issue, and of supply if different | Required | Date of issue only |
| Line detail, discount, totals and tax in AED | Required | Total and tax only |
In full, a compliant invoice carries the "Tax Invoice" heading and both parties' details. It also needs a unique number, the relevant dates, and a description of what was supplied. For each line it shows unit price, quantity, tax rate, and the amount payable in dirhams. It shows any discount, the gross amount, and the tax amount in dirhams. Where a currency conversion applies, it shows the rate used. Where the reverse charge applies, it carries a statement to that effect.
When a Simplified Invoice Is Allowed
This is where published guidance most often goes wrong, so it is worth stating precisely.
A simplified invoice is permitted in two situations. The first is where the recipient is not VAT registered. There is no value ceiling in that case. The second is where the recipient is registered and the consideration does not exceed AED 10,000.
So the AED 10,000 figure is a cap on simplified invoicing between businesses. It is not a general threshold below which anyone may use the short format. A retailer selling to consumers can use simplified invoices for any amount.
One practical caution. A simplified invoice carries no recipient name or registration number. Registered buyers often ask for a full invoice on small purchases anyway, so their recovery position is not arguable later. Supplying one is reasonable even where the rules do not compel it.

The general deadline is 14 days from the date of supply. A supply on 1 April means an invoice by 15 April.
The date of supply is the trigger, not the date you get round to billing. For services delivered over time, that distinction needs care. Reported guidance also indicates simplified invoices should be issued on the date of supply itself. The 14 day window does not apply there.
Specific exceptions exist for certain cases. Check your own supply type rather than assuming the general rule covers it.
Foreign Currency and Language
Two formatting points cause avoidable rejections.
On currency, you may invoice in any currency. The tax amount must still appear in dirhams, together with the exchange rate applied. Published guidance indicates the Central Bank rate on the date of supply is the accepted basis. Showing a converted figure with no stated rate is a common defect.
On language, invoices may be issued in Arabic or bilingually. The authority can request an Arabic translation of any document, which is why bilingual templates are widely used. An English only invoice is generally workable in practice, but the ability to produce an Arabic version should exist.
Reverse Charge Supplies
Where the recipient accounts for the tax, the invoice must say so. A statement that the recipient is required to account for the tax is one of the twelve particulars, along with a reference to the relevant provision.
A simplified invoice cannot be used for a reverse charge supply. Whatever the value, a full tax invoice is required. This catches out suppliers of electronic devices and precious metals, where domestic reverse charge treatment applies between registered businesses.
Reporting also indicates a recent change. A requirement for the recipient to self-issue an invoice under the reverse charge was reportedly removed from the start of 2026. The duty to retain supporting documentation remains. Confirm the current position before changing any process.
Electronic Invoicing and What Changes
A phased move to structured electronic invoicing has been reported, with a rollout beginning in 2026.
The reported model is decentralised, with invoices passing through accredited service providers rather than a central government portal. The practical shift is from documents to data. A PDF that looks correct is not the same as a structured file carrying every required field.
One reported consequence matters for template planning. Businesses inside the electronic invoicing system are said to lose access to the simplified invoice format entirely, whatever the value or the customer type. If that holds, retailers and small businesses will need full invoice data for every sale. Design templates now so they can carry the full field set.
What a Defective Invoice Costs
Penalties apply for failing to issue a compliant tax invoice, and reporting puts the figure at AED 2,500 for each detected case. That accumulates quickly across a sales ledger.
The indirect cost is often larger. A customer denied VAT recovery because of your invoice will ask you to fix it, and may withhold payment until you do. Getting the template right once is cheaper than correcting invoices individually.
Checking Your Template
Most invoicing problems come from a template built once and never reviewed. Check your current invoice field by field against Article 59. Pay attention to the reverse charge statement and the exchange rate line, which are the two most often missing. Confirm that your system stamps the date of supply rather than only the date of issue. Then plan for structured electronic invoicing. A template that cannot carry the full field set will need rebuilding rather than editing.
