Published: 17 October 2026

Every VAT-registered business in the UAE lives and dies by its invoices. The invoice you issue is the document your customer uses to claim input VAT, the document the Federal Tax Authority (FTA) asks for in an audit, and the document that proves your own output VAT was reported correctly. A missing Tax Registration Number, a wrong date or a credit note issued three weeks late can cost your customer their VAT recovery and cost you an administrative penalty.

This guide sets out what the law actually requires for a tax invoice and a tax credit note in 2026: the fields, the simplified invoice option, the 14-day deadlines, the record-keeping duty and the penalty for getting it wrong. Every rule below is taken from Federal Decree-Law No. 8 of 2017 on VAT and its amendments, Cabinet Decision No. 52 of 2017 (the Executive Regulation) and its amendments, and Cabinet Decision No. 40 of 2017 on administrative penalties. Where a point depends on FTA guidance we have not been able to confirm, we say so.

Quick Answer: What Makes a UAE Tax Invoice Valid?

A UAE tax invoice is valid only if it carries the words “Tax Invoice”, the supplier’s name, address and TRN, a unique sequential number, the issue date, a description of the goods or services, the amounts in AED and the VAT charged. It must be issued within 14 days of the date of supply. A tax credit note must be issued within 14 days of the event that reduces the VAT, such as a cancellation, a return or a price change.

The legal basis sits in three places:

Rule	Where it is found
Duty to issue and deliver an original tax invoice	Article 65, Federal Decree-Law No. 8 of 2017
14 days from the date of supply	Article 67, Federal Decree-Law No. 8 of 2017
Required invoice fields	Article 59, Cabinet Decision No. 52 of 2017
Required credit note fields	Article 60, Cabinet Decision No. 52 of 2017
Credit note within 14 days of the triggering event	Article 62(2), Federal Decree-Law No. 8 of 2017
Penalty for late or missing invoice or credit note	Cabinet Decision No. 40 of 2017, as amended

Who Must Issue a Tax Invoice?

A registrant making a taxable supply must issue an original tax invoice and deliver it to the recipient (Article 65(1) of the Decree-Law). A registrant making a deemed supply issues an original tax invoice to the recipient if there is one, or keeps it in its own records if there is none (Article 65(2)).

Two further points from Article 65 catch businesses by surprise:

Anyone who issues a tax invoice showing VAT must pay that VAT to the FTA. Article 65(4) says any person receiving an amount as tax, or issuing a tax invoice in respect of an amount, must pay that amount to the Authority. So a business that is not registered must never put VAT on an invoice, and a registered business cannot “cancel” VAT it has already invoiced just by deciding it was a mistake. The correction route is a credit note, covered below.
Wholly zero-rated supplies have a limited exception. A taxable person is not required to issue a tax invoice for a wholly zero-rated supply if sufficient records exist to establish the particulars of the supply (Article 59(3) of the Executive Regulation). Most businesses still issue one, because the customer, the bank or the customs file will ask for it.

If you are not yet registered, start with our UAE VAT registration guide, because the invoice rules only apply once you hold a TRN.

The 12 Mandatory Fields of a Full Tax Invoice

Article 59(1) of the Executive Regulation lists what a full tax invoice must contain. The English wording used in the official translation is below, put into a checklist you can compare with your own template.

#	Required particular
a	The words “Tax Invoice” clearly displayed
b	Name, address and Tax Registration Number of the registrant making the supply
c	Name, address and TRN of the recipient, where the recipient is a registrant
d	A sequential tax invoice number, or a unique number that identifies the invoice and its order in the sequence
e	Date of issue
f	Date of supply, if different from the date of issue
g	Description of the goods or services supplied
h	For each item: unit price, quantity or volume, rate of tax and the amount payable in AED
i	Amount of any discount offered
j	Gross amount payable in AED
k	Tax amount payable in AED, with the rate of exchange used if the original currency is not dirhams
l	Where the recipient must account for the tax (reverse charge), a statement to that effect and a reference to the relevant provision of the Decree-Law

A few practical notes on the fields that cause the most errors:

TRN and address (b, c). Both the name and the address must match the registration. A TRN with a trading name that differs from the registered legal name is a frequent audit finding.
Number (d). The law accepts either a sequential number or any unique number that lets the FTA identify the invoice and its position in the sequence. Gaps are not illegal by themselves, but you must be able to explain every missing number.
Two dates (e, f). If you invoice on a different day from the supply, show both. The date of supply, not the invoice date, decides which VAT return the transaction belongs to under Articles 25 and 26 of the Decree-Law.
AED amounts (h, j, k). If you invoice in dollars or euros, the VAT amount must still be shown in AED. Article 69 of the Decree-Law says the amount is converted at the exchange rate approved by the Central Bank of the UAE on the date of supply. Show that rate on the invoice.
Discounts (i). A discount that is not shown on the invoice cannot be assumed by your customer when calculating the VAT they recover.
Reverse charge (l). The statement is required when the recipient accounts for the tax. Read our UAE VAT reverse charge guide for the supplies this covers. Our earlier article on the 2026 VAT law amendments explains that a separate self-invoice for reverse-charge purchases is no longer needed, so check which of your documents are still mandatory.

Simplified Tax Invoices: When You Can Use One

A full invoice is the default. Article 59(5) allows a lighter document, called a simplified tax invoice, in two situations:

The recipient is not a registrant, for example a retail customer.
The recipient is a registrant and the consideration for the supply does not exceed AED 10,000.

A simplified tax invoice has five mandatory particulars (Article 59(2)):

#	Simplified invoice particular
a	The words “Tax Invoice” clearly displayed
b	Name, address and TRN of the supplier
c	Date of issue
d	Description of the goods or services
e	Total consideration and the tax amount charged

What this means in practice: a restaurant, shop or salon can issue a till receipt that meets those five points. A consulting firm invoicing a VAT-registered client for AED 25,000 cannot, and must issue the full version. Where the amount is exactly or below AED 10,000 and the client is a registrant, you may use the simplified format, but many suppliers still prefer the full format so the customer’s accounts team can post it without asking for more information.

Other Invoice Types the Regulation Recognises

Article 59 also allows a few special cases. They are less common but matter for the businesses that use them:

Summary invoices. Where you make more than one supply to the same customer in a calendar month, you may issue a summary tax invoice instead of separate invoices for each supply (Article 59(6)).
Electronic invoices. You can issue a tax invoice by electronic means if you can store a copy securely, in line with the record-keeping rules, and the authenticity of origin and integrity of content are guaranteed (Article 59(8)). This is the current VAT rule on electronic copies. It is separate from the mandatory national e-invoicing system; see our guides on UAE e-invoicing requirements and penalties and e-invoicing penalties.
Invoices raised by the buyer. If the buyer is a registrant and both sides agree in writing that the supplier will not issue invoices, the buyer can raise the tax invoice. It must contain the full particulars and show the words “Tax Invoice raised by buyer” (Article 59(9)). Any invoice the supplier also issues for that supply is then deemed not to be a tax invoice (Article 59(10)).
Agents. A registered agent supplying on behalf of a principal may issue the tax invoice as if the agent made the supply, and in that case the principal does not issue one (Article 59(11)).
Supplies treated as made in another GCC Implementing State. Extra particulars are required, including the recipient’s TRN issued by that State and a statement that the supply is between the UAE and an Implementing State (Article 59(12)).
FTA waivers. Where the Authority considers records are sufficient and an invoice is impractical, it can determine that certain particulars are not needed or that no invoice is required for particular cases (Article 59(7)). This applies only if the FTA has actually said so for your case.

The 14-Day Deadline for Issuing a Tax Invoice

Article 67(1) of the Decree-Law says the registrant must issue a tax invoice within 14 days from the date of supply, as determined under Article 25 or Article 26. Article 67(2) allows the Executive Regulation to set different periods for specific cases, or require immediate issue in some cases under specified controls.

How to apply this:

Identify the date of supply first. For goods it is generally when they are transferred or made available; for services, when the service is completed; and for continuous supplies, other triggers such as the invoice date or payment due date can apply. The rules are in Articles 25 and 26 of the Decree-Law.
Count 14 days from that date, not from the date the customer asks for the invoice and not from the date you receive payment.
If you are paid in advance, check Articles 25 and 26, because a payment received can bring forward the date of supply for the amount paid, and the 14 days then run from that earlier date.
Check whether a special period applies. If you rely on a different period for a specific class of supplies (for example, summary invoices), confirm the exact current wording of the Executive Regulation or the relevant FTA guidance. We could not verify every special-period exception in the consolidated text published by the FTA, so do not assume one without checking.

Tax Credit Notes: When One Is Required

A tax credit note is the legal way to reduce VAT already charged. Article 61(1) of the Decree-Law lists when a registrant must adjust output tax after the date of supply:

the supply was cancelled;
the tax treatment changed because the nature of the supply changed;
the agreed consideration was altered for any reason;
the customer returned the goods or services in full or part and the consideration was returned in full or part; or
tax was charged, or a tax treatment applied, in error.

Article 62 then sets the mechanism:

Situation	What you do	Deadline
Output tax due is more than you charged	Issue a new tax invoice for the additional tax and report it in the tax period in which the increase was identified	Per the normal invoice rules
Output tax charged is more than should have been charged	Issue a tax credit note	Within 14 days of the date on which the Article 61(1) event took place

Article 63 explains why the credit note matters to both sides. The tax on the credit note reduces the issuer’s output tax and reduces the recipient’s input tax for the tax period in which the recipient received the credit note. If you never issue it, your customer keeps a VAT deduction it should no longer have, and you may keep paying VAT on revenue you did not collect.

Mandatory fields of a tax credit note

Article 60(1) of the Executive Regulation lists seven particulars:

#	Required particular
a	The words “Tax Credit Note” clearly displayed
b	Name, address and TRN of the supplier
c	Name, address and TRN of the recipient, if the recipient is a registrant
d	Date of issue
e	The value of the supply shown on the original tax invoice, the correct value, the difference between the two and the tax relating to that difference, in AED
f	A brief explanation of why the credit note is being issued
g	Information sufficient to identify the supply the credit note relates to

A recent wording change: Cabinet Decision No. 149 of 2026, which amends parts of the VAT Executive Regulation and takes effect from 1 October 2026, replaces paragraph (a) of Article 60(1). It now reads that the words “Tax Credit Note” must be clearly displayed “on the credit note”, where the earlier text said “on the invoice”. The practical result for you is simple: the heading must say “Tax Credit Note” on the document itself. For the wider package of changes in that decision, read our guide to Cabinet Decision 149 of 2026.

Like tax invoices, credit notes can be issued electronically if you can store a copy securely and guarantee origin and integrity (Article 60(3)). The buyer can also raise a credit note if both parties agree and the document shows “Tax Credit Note created by buyer” (Article 60(4)). The FTA can, on application, allow certain particulars to be left out or confirm that no credit note is required (Article 60(2)), but only for cases it has approved.

A worked example

A Dubai trading company invoices a client AED 40,000 plus 5% VAT of AED 2,000 on 3 March. On 10 March the client returns part of the goods and the company agrees to refund AED 10,000 of the value.

The event (return and refund) happens on 10 March, so the credit note is due by 24 March.
The credit note shows the original value AED 40,000, the corrected value AED 30,000, the difference AED 10,000 and the VAT on the difference, AED 500.
The company reduces its output VAT by AED 500, and the client reduces its input VAT by AED 500 in the period it receives the note.

If the company only issues the credit note on 9 April, it has missed the 14-day deadline and is exposed to the penalty below, even though the underlying correction is legitimate.

FTA Penalties for Invoice and Credit Note Errors

The administrative penalties are set in Cabinet Decision No. 40 of 2017, as amended. In the consolidated text published by the Ministry of Finance (version dated 14 November 2025), the relevant lines for invoices are:

Violation	Penalty
Failing to issue a tax invoice, or the alternative document, when making a supply within the legally specified period	AED 2,500 for each detected case
Failing to issue a tax credit note, or the alternative document, within the legally specified period	AED 2,500 for each detected case
Failing to follow the conditions and procedures for issuing tax invoices and tax credit notes electronically	AED 2,500 for each detected case
Failing to keep the required records and other information	AED 10,000 for each violation, or AED 20,000 for a repeated violation within 24 months of the last violation

Two points deserve attention. First, the penalty is per detected case, so a systemic fault, such as a template that omits the TRN or a team that issues every credit note late, can multiply quickly during an audit. Second, the table was amended by Cabinet Decision No. 129 of 2025 with effect from 14 April 2026, so older figures quoted in blogs and training material may be out of date. For the full picture, see our guides to the 2026 tax penalty regime under Cabinet Decision 129 of 2025 and the 14 April 2026 penalty changes.

The invoice penalty is also not the only cost. If the FTA finds a customer claimed input VAT on an invoice that did not meet Article 59, it can deny that recovery, which becomes a commercial problem between you and the client. And if the problem is a client who simply will not pay a valid invoice, Yalah Dubai explains how small claims work in Dubai.

Record-Keeping: What to Keep and for How Long

Article 78 of the Decree-Law requires a taxable person to keep, among other records, all tax invoices and alternative documents issued, all tax credit notes issued, all those received, records of supplies and imports, and records of adjustments or corrections made to accounts or tax invoices.

On retention periods:

The Executive Regulation says records must follow the timeframes in the Tax Procedures law (Article 71(1) of the Executive Regulation). Confirm the current period in the Tax Procedures law and its Executive Regulation, because that law has been amended since 2017.
Records relating to real estate must be kept for 15 years after the end of the tax period to which they relate (Article 71(2)).

If your finance team stores invoices as PDFs, make sure the file you keep is the same document the customer received, and that you can retrieve it quickly by number, customer or date. See our bookkeeping requirements for UAE businesses for a practical filing structure.

Common Invoice Mistakes and How to Prevent Them

Mistake	Why it matters	Fix
Title says “Invoice” and not “Tax Invoice”	The mandatory wording is missing	Change the template heading
Customer TRN missing on a B2B invoice	The recipient may lose input VAT recovery	Collect and validate TRNs at onboarding
VAT shown only in foreign currency	AED amount is mandatory	Add the AED VAT and the exchange rate used
Supply date not shown when it differs from invoice date	The VAT period can be wrong	Add a “date of supply” field
Credit note issued after 14 days	Penalty risk and wrong VAT period	Set a reminder from the date of the return or price change
Editing or deleting an issued invoice	Breaks the sequence and the audit trail	Issue a credit note and a new invoice instead
Charging VAT while not registered	The VAT charged must be paid to the FTA (Article 65(4))	Do not show VAT until you hold a TRN

If you discover that you reported the wrong amount on a past return because of a faulty invoice, our guide to VAT voluntary disclosure explains how to correct it before the FTA does, and common VAT mistakes in the UAE covers the wider list.

A Simple Monthly Invoice Control

A short monthly check reduces most of the risk:

Run a report of all invoices issued in the month and check that the numbers are unbroken or every gap is explained.
Sample at least ten invoices against the 12-field table above.
List every refund, return, cancellation and price change in the month and match each to a credit note issued within 14 days.
Check that every foreign-currency invoice shows the AED VAT and the exchange rate.
Reconcile output VAT in the ledger to the VAT return before you file. Our complete VAT return filing guide sets out the filing steps.

Frequently Asked Questions

What is a tax invoice in the UAE?

It is a written or electronic document that records a taxable supply and shows the VAT charged, in the format required by Article 59 of Cabinet Decision No. 52 of 2017. A registrant making a taxable supply must issue the original and deliver it to the recipient.

Within how many days must a UAE tax invoice be issued?

Within 14 days from the date of supply, under Article 67(1) of Federal Decree-Law No. 8 of 2017. The Executive Regulation can set other periods for particular cases, so check whether one applies to your supply.

Can I use a simplified tax invoice for a B2B sale?

Yes, but only if the consideration does not exceed AED 10,000. If the recipient is not a registrant, a simplified invoice can be used whatever the amount. Above AED 10,000 to a VAT-registered customer, you must issue a full tax invoice.

Does the invoice have to be in Arabic?

The Executive Regulation requires the particulars listed in Article 59 but does not, in the text we reviewed, set a language rule for the invoice itself. Many businesses issue invoices in English or in both languages. The FTA can require documents in Arabic when it asks for records during an audit, and the penalty table includes a line for failing to submit tax records in Arabic when requested, so keep translations ready.

What is the penalty for not issuing a tax invoice on time?

AED 2,500 for each detected case, under the consolidated text of Cabinet Decision No. 40 of 2017. The same amount applies to a late or missing tax credit note.

When do I need to issue a tax credit note?

When output VAT must be reduced because the supply was cancelled, its nature changed, the agreed price changed, goods were returned and money refunded, or VAT was charged by mistake. It must be issued within 14 days of that event.

What must a tax credit note show?

Seven particulars: the words “Tax Credit Note”, the supplier’s details, the recipient’s details if registered, the issue date, the original value, correct value, difference and VAT on the difference in AED, a short explanation, and information that identifies the original supply.

Can I correct a wrong invoice by editing it?

No. Once a tax invoice has been issued and delivered, treat it as a fixed record. If it overstated VAT, issue a tax credit note. If it understated VAT, issue a new tax invoice for the additional tax. Editing it destroys the audit trail.

Does the e-invoicing system change these rules?

The national electronic invoicing system is a separate programme with its own timetable and penalties. The VAT rules above still decide what a valid tax invoice and credit note must contain. Follow our e-invoicing guide for the rollout dates that apply to your business.

How long must I keep invoices and credit notes?

Retention periods are set by the Tax Procedures law, as the VAT Executive Regulation points to it, with 15 years for real estate records. Confirm the current period with the FTA or your tax adviser before disposing of any document.
