What a tax invoice has to contain, and the fields that get left off
Nobody argues about the 5%. The arguments are about whether the piece of paper carrying it was a tax invoice at all, and that is decided by a list most accounting systems only half implement.

In short
Article 59 of Cabinet Decision No. 52 of 2017 requires a UAE tax invoice to show the words "Tax Invoice", supplier and recipient details including TRNs, a unique invoice number, the dates of issue and supply, a description, and the amounts and tax in AED. It is due within 14 days of the date of supply. Failing to issue one costs AED 5,000 per document.
The short version
- The words Tax Invoice have to appear. It is a named requirement, not a formatting habit.
- The recipient TRN is mandatory only where the recipient is registered, and that is the field most often blank.
- Amounts payable and the tax itself must be stated in AED, with the exchange rate and its source where you converted.
- AED 5,000 per document for failing to issue a compliant tax invoice or credit note.
- 14 days from the date of supply. The date of supply, not the date you got round to invoicing.
The list, and the three fields systems get wrong
Most UAE businesses do not fail VAT on the rate. They fail it on the document.
Article 59 of Cabinet Decision No. 52 of 2017 sets out what a tax invoice must contain. It reads as a plain list, and the temptation is to skim it because your accounting software prints something that looks right. The list is worth reading slowly, because software prints what it was configured to print.
A full tax invoice has to show all of the following:
| Field | Note |
|---|---|
| The words Tax Invoice | Clearly displayed. Not Invoice, not Bill. |
| Supplier name, address and TRN | The registrant making the supply. |
| Recipient name, address and TRN | TRN required where the recipient is a registrant. |
| Sequential or unique invoice number | Must identify the document and its order in the sequence. |
| Date of issue | The day the invoice was raised. |
| Date of supply | Only where it differs from the date of issue. It often differs. |
| Description of goods or services | Per line. |
| Unit price, quantity, tax rate, amount payable in AED | Per line, in AED. |
| Discount offered | Where one applies. |
| Gross amount payable in AED | The total. |
| Tax amount payable in AED | With the exchange rate and its source where converted. |
| Reverse charge statement | Where the recipient must account for the tax. |
Three of those are where real invoices fall down, and they are always the same three.
The recipient TRN. It is mandatory when your customer is registered. Sales systems tend to treat it as an optional customer field, so it is populated for the customers who asked and blank for everyone else. Blank is the default state of an optional field.
The date of supply. Systems print the invoice date because that is the date they know. The date of supply is a legal conclusion about when the supply happened, and for advance payments, continuous supplies and retention it is frequently a different day. Where it differs, it has to appear.
The AED amounts. If you invoice in dollars or euros, the tax has to be stated in AED, and you have to show the exchange rate you used and where it came from. An invoice that shows only the foreign currency total, with a VAT line in the same currency, is not complete.
Fourteen days, and the date that starts them
The invoice is due within 14 days of the date of supply.
That is a short window, and it runs from the supply, not from month end, not from the day the project manager signs off the timesheet, and not from the day your billing run happens to fall. A business that invoices monthly in arrears on the fifth of the following month is outside 14 days for everything supplied before the twentieth of the month before.
In practice the FTA is more interested in whether the invoice exists, is complete, and lands in the right tax period than in a few days of slippage on a supply that was properly returned. That is a comment on where attention goes, not permission. The rule is 14 days.
Where it bites hardest is the period boundary. A supply made on 26 March, invoiced on 8 April, still belongs to the March period. Businesses that let the invoice date decide the period will put it in April, and the correction later is a voluntary disclosure rather than a tidy-up.
Simplified invoices, and the change most people have not priced in
A simplified tax invoice is the short form. It needs the words Tax Invoice, the supplier name, address and TRN, the date of issue, a description of what was supplied, and the total consideration with the tax amount. No recipient details, no line-by-line tax breakdown.
You may issue one where the recipient is not registered, or where the recipient is registered and the consideration does not exceed AED 10,000. That is the rule retail, food service and small-ticket trade have run on since 2018.
Here is the part worth flagging now rather than in a year. Cabinet Decision No. 100 of 2025, effective 29 September 2025, amended Articles 59 and 60. Under the e-invoicing framework the concept of the simplified tax invoice is removed: a business inside that regime issues a structured e-invoice regardless of value, and the AED 10,000 short cut stops being available to it.
What that means depends entirely on whether you are in the regime yet. The e-invoicing timetable is staged, and the first mandatory wave is businesses above AED 50 million in revenue. If that is not you, the simplified invoice rules above still describe your obligations today.
What is genuinely unsettled: the treatment of the overlap period, for businesses not yet in scope, has not been spelled out in a published FTA clarification. We are not going to tell you it has been. Plan on the basis that simplified invoicing has an end date attached to your own e-invoicing wave, and confirm the detail before you rebuild a till system around it. Our note on the ASP appointment deadline sets out which wave you are in.
What a missing field costs, on both sides
There are two separate costs, and businesses usually only think about the first.
Your penalty. Failing to issue a tax invoice or a tax credit note when required is AED 5,000 per document. Per document. A billing template that omits a mandatory field is not one mistake, it is one mistake replicated across every invoice that template produced.
Run the arithmetic on a small trading company issuing 40 invoices a month with the recipient TRN left blank. That is not a AED 5,000 exposure. Nobody assesses it that way in practice, and a first conversation with the Authority is usually about fixing the template. But the number in the schedule is per document, and it is worth knowing that before you argue about whether a field matters.
Your customer's problem. This is the one that damages relationships. Input tax recovery is supported by holding a valid tax invoice. Hand your customer a document that is not one, and their claim is exposed while yours is merely penalised. Finance teams at larger buyers now check supplier invoices on receipt and reject them, which is why a compliant template is a commercial matter and not only a tax one.
If you are separately worried about whether a technically perfect invoice is enough to protect a claim, it no longer is on its own. We covered that in the new denial rule.
There is also a record-keeping layer under this. Invoices and credit notes are part of the records you must keep for five years, fifteen for real estate, and failure to keep required records runs at AED 10,000 first time and AED 20,000 for a repeat.
Two 2026 changes that alter what a good invoice looks like
Federal Decree-Law No. 16 of 2025 took effect on 1 January 2026 and moved two things worth knowing.
The self-invoice is gone. A taxable person importing concerned goods or services under the reverse charge is no longer required to issue a tax invoice to itself. The supplier's invoice and the contract carry the evidence. The duty to account for the tax has not changed at all: output in Box 3, input in Box 10. Businesses that built a self-billing routine to satisfy the old wording can retire it, and should stop treating a missing self-invoice as an exposure. The detail sits in our piece on reverse charge on imported services.
A valid invoice stopped being a complete answer. The Authority must now deny input tax where the supply formed part of a chain connected with tax evasion and the recipient knew or should have known. A correct Article 59 invoice does not cure that. How should have known gets applied is not yet settled by any published UAE decision, so treat supplier diligence as a live obligation rather than a paperwork one.
The check we run, in order
When a client sends an invoice template, this is the sequence. It takes about ten minutes and it catches almost everything.
- Do the words Tax Invoice appear, spelled that way?
- Supplier TRN present and matching the certificate, digit for digit?
- Recipient TRN present for every registered customer, not just the ones who asked?
- Is the number sequential and unique across the whole series, including credit notes?
- Does a date of supply field exist at all, and does it populate when it differs from the issue date?
- Are the line amounts, the gross and the tax stated in AED?
- If you invoice in another currency, is the exchange rate shown, and its source named?
- Does a reverse charge statement appear on the supplies that need it?
- Does the credit note template carry the same fields plus the reference to the original invoice?
Number nine is the one people skip. Credit notes are governed alongside invoices, they carry the same AED 5,000 exposure, and they are almost always an afterthought in a billing system. We find more defective credit notes than defective invoices.
Fix the template once and the problem stops being recurring. Leave it and every month adds documents to the pile.
Questions we get asked
What must a UAE tax invoice contain?
Article 59 of Cabinet Decision No. 52 of 2017 requires the words "Tax Invoice", the supplier name, address and TRN, the recipient name, address and TRN where the recipient is a registrant, a sequential or unique invoice number, the date of issue, the date of supply where it differs, a description of the goods or services, the unit price, quantity, tax rate and amount payable in AED, any discount, the gross amount payable in AED, and the tax amount in AED including the exchange rate and its source where a conversion was made.
How long do I have to issue a tax invoice in the UAE?
Fourteen days from the date of supply, under Article 67 of Federal Decree-Law No. 8 of 2017 read with Article 59 of Cabinet Decision No. 52 of 2017. The period runs from the date of supply rather than from the invoice date or a monthly billing run, so a supply made near a period end can belong to the earlier tax period even though the invoice was raised in the next one.
What is the penalty for an incorrect tax invoice in the UAE?
AED 5,000 for each document where a person fails to issue a tax invoice or a tax credit note as required. The charge is per document, so a defective template applies it to every invoice that template produced. Separately, failure to keep required records is AED 10,000 for a first offence and AED 20,000 for a repeat.
When can I still issue a simplified tax invoice?
Where the recipient is not registered for VAT, or where the recipient is registered and the consideration does not exceed AED 10,000. A simplified invoice needs the words "Tax Invoice", the supplier name, address and TRN, the date of issue, a description of the supply, and the total consideration with the tax amount. Cabinet Decision No. 100 of 2025 removes the simplified invoice within the e-invoicing framework, so the concession ends for a business once its e-invoicing wave begins.
Does my customer lose input tax if my invoice is missing a field?
It puts the claim at risk. Input tax recovery is supported by holding a valid tax invoice, so a document missing a mandatory particular is a weaker record than a complete one. Since 1 January 2026 the reverse is also true: under Federal Decree-Law No. 16 of 2025 a technically valid invoice does not by itself protect a claim where the supply formed part of a chain connected with tax evasion and the recipient knew or should have known.
Do I still need to issue myself a tax invoice under reverse charge?
No. Federal Decree-Law No. 16 of 2025, in force 1 January 2026, removed the requirement for a taxable person importing concerned goods or services under the reverse charge to issue a tax invoice to itself. The supplier invoice and the contract carry the evidence. The obligation to account for the tax is unchanged, with output tax in Box 3 and the corresponding input tax in Box 10.
