Tax Invoices in the UAE — Required Information, Formats & the Move to E-Invoicing

What a Tax Invoice in the UAE Must Actually Contain

Every VAT-registered business in the UAE is required to issue a tax invoice for any supply of taxable goods or services, a requirement set out in Article 59 of the VAT Executive Regulations under Cabinet Decision No. 52 of 2017. Whether that invoice is generated as a structured e-invoice or produced manually as a PDF or paper document, the Federal Tax Authority expects the same core set of mandatory fields to be present — and missing even one of them can invalidate the invoice for input VAT recovery purposes, regardless of whether the underlying VAT was calculated correctly.

This guide sets out exactly what belongs on a UAE tax invoice, the difference between the two invoice formats the law permits, how foreign currency and rounding should be handled, and a significant regulatory change — the move to mandatory e-invoicing from July 2026 — that will eliminate one of those formats entirely for businesses brought into its scope.

What Is a Tax Invoice in the UAE?

A tax invoice is the legal document a VAT-registered business issues to record a taxable supply, stating the supplier, the customer, both parties’ Tax Registration Numbers where applicable, a unique invoice number, and the VAT amount due. It is this document — not a quotation, a proforma invoice, or a general commercial invoice used for customs purposes — that supports a buyer’s claim for input VAT recovery with the FTA.

Types of Tax Invoices in the UAE

Article 59 of the VAT Executive Regulations recognizes two distinct invoice formats, with the dividing line set by the value of the supply.

Standard (Full) Tax Invoice

A full tax invoice is required for any taxable supply exceeding AED 10,000 inclusive of VAT, and is the format generally expected for business-to-business transactions between VAT-registered parties. It carries the most complete set of details a UAE tax invoice can require:

• Supplier’s TRN and the recipient’s TRN, where the recipient is VAT-registered
• Invoice date and, where different, the date of supply
• VAT rate, VAT amount per line item, and the total amount payable
• Unit price, quantity, and any discount applied before VAT is calculated
• Reverse-charge treatment, where the supply is subject to the reverse-charge mechanism

A supplier in Abu Dhabi selling AED 25,000 of office furniture to a VAT-registered company in Dubai, for example, must issue a full tax invoice showing both parties’ TRNs and a complete VAT breakdown — the transaction value alone places it well above the AED 10,000 threshold that would otherwise permit a simplified format.

Simplified Tax Invoice

A simplified tax invoice can be used for supplies valued at AED 10,000 or below, and is the format most commonly seen in retail and other business-to-consumer settings. It requires considerably less detail than a full invoice — typically the supplier’s name, address, and TRN, the invoice date, a description of the goods or services, the VAT rate and amount, and a unique invoice number — and specifically does not require the recipient’s name, address, or TRN.

A Dubai café selling AED 200 of food to a walk-in customer can issue a simplified tax invoice showing only the supplier’s details and the total VAT, without needing to capture anything about the customer at all. The trade-off is recovery: a simplified invoice does not give the recipient the documentation needed to support an input VAT recovery claim, so a VAT-registered buyer who needs to reclaim VAT on a purchase below AED 10,000 should specifically request a full tax invoice rather than accept the simplified default.

Mandatory Details on a UAE Tax Invoice

Regardless of format, every tax invoice in the UAE needs to contain the particulars the FTA specifies, and omitting any of them creates real exposure — both to non-compliance penalties and to rejection of the invoice during a VAT audit.

• Supplier’s details — legal business name exactly as registered, address, and TRN
• Recipient’s details — name, address, and TRN where the recipient is VAT-registered
• Sequential invoice number — continuous, logical numbering that allows the invoice’s position in a sequence to be identified; non-sequential or duplicate numbering is a frequent finding in FTA audits
• Invoice date and date of supply, where these differ
• Item description, unit price, and quantity supplied
• Tax rate, VAT amount, and total amount including VAT
• Discount details, where a discount has been applied — discounts must be deducted before VAT is calculated, not after

A company selling AED 5,000 of clothing, for instance, needs its invoice to show something along the lines of “Shirts — 50 units @ AED 100 each — VAT 5% = AED 250 — Total AED 5,250,” a level of itemized detail that lets the supplier, the customer, and the FTA all independently verify the transaction from the same document.

Tax Invoices in Foreign Currency and Rounding Rules

Where a UAE business issues an invoice in a foreign currency, the VAT amount itself must still be expressed in AED, converted using the official Central Bank exchange rate applicable on the date of supply.

A few rules govern how that conversion and any resulting rounding should be handled:

• Every foreign currency tax invoice must show the VAT amount in AED, not solely in the invoice’s original currency
• Rounding to the nearest fils is permitted on the gross AED amount
• A business should apply either consistent line-item rounding or rounding at the gross value level — not a mix of both within the same invoice
• Both the net amount and the gross amount should be clearly shown in AED

A Dubai-based exporter invoicing a customer USD 1,000, with a supply-date exchange rate of 3.67 AED/USD, would calculate VAT as 5% of $50, converted at 3.67 to reach AED 183.50 — rounded to AED 184 on the invoice.

Compliance Requirements and the 14-Day Issuance Rule

The FTA enforces UAE VAT invoicing under Article 59 and Article 60 of the VAT Executive Regulations, which together govern how a tax invoice must be issued, delivered to the recipient, and retained in the supplier’s records.

The central timing rule is straightforward: a tax invoice must generally be issued within 14 days of the date of the taxable supply. A business that supplies goods on 1 April, for example, must issue the corresponding tax invoice no later than 15 April to remain within the 14-day window. Beyond timing, the invoice’s format must follow the structure Article 59 prescribes, the taxable amount payable must be clear and independently traceable from the figures shown, and the supplier must maintain proper records of every invoice issued. Non-compliance with these requirements exposes a business to administrative penalties under the UAE’s VAT penalty framework.

A Major Change on the Way — Mandatory E-Invoicing and the End of Simplified Invoices

Businesses relying on the simplified invoice format described above should be aware of a significant shift already in motion. Cabinet Decision No. 100 of 2025, effective 29 September 2025, amended Articles 59 and 60 of the VAT Executive Regulations specifically to prepare for the UAE’s move to mandatory e-invoicing, which begins rolling out from July 2026.

Once a business is brought into the e-invoicing system — whether through the mandatory rollout or by adopting it voluntarily ahead of schedule — several reliefs currently available under Articles 59 and 60 fall away entirely:

• Simplified invoice and credit note formats will no longer be permitted, even for transactions below AED 10,000 or supplies to non-registered customers — every invoice must instead carry the full set of data fields the FTA’s e-invoicing schema requires
• Administrative exceptions previously granted by the FTA for not issuing a tax invoice or credit note at all will no longer be available once a business is within the e-invoicing system
• Tax invoices become mandatory even for wholly zero-rated supplies, removing a relief that previously allowed some zero-rated suppliers to rely on internal records rather than issue a formal invoice

For retail and other high-volume, low-value businesses that currently lean heavily on simplified invoices, this is a meaningful operational shift, not just a paperwork update — it requires capturing complete customer master data (name, address, TRN where applicable) for transactions that previously needed almost none of it. Businesses expecting to fall within the July 2026 rollout, or considering voluntary early adoption, should begin reviewing their invoicing systems and customer data capture well ahead of that date rather than waiting for the mandatory deadline to arrive.

Common Tax Invoice Errors That Trigger FTA Findings

• Issuing a simplified invoice above the AED 10,000 threshold — one of the most frequent findings in FTA audits
• Missing or incorrect “Tax Invoice” labeling — generic accounting templates sometimes default to “Invoice” or “Commercial Invoice,” which the FTA does not treat as equivalent
• Non-sequential or duplicate invoice numbering — breaks the traceable sequence the FTA expects and is treated as an audit red flag
• Applying the wrong VAT rate — charging 5% on a zero-rated or exempt supply, or 0% on a standard-rated one, directly distorts VAT return accuracy
• Failing to show VAT as a separate, clearly stated amount — folding VAT into a single total price without a distinct VAT line
• Mismatched invoice and supply dates — using the same date for both by default, even when the actual supply happened on a different date, which can misalign which VAT return period the transaction belongs in

Frequently Asked Questions (FAQs)

What is a tax invoice in the UAE?

A tax invoice is the document a VAT-registered business in the UAE issues for a taxable supply of goods or services, stating the supplier, the customer, their TRNs where applicable, a unique invoice number, and the VAT amount due. It is the document that supports input VAT recovery claims.

What is the difference between a standard and a simplified tax invoice?

A standard tax invoice is required for supplies exceeding AED 10,000 and includes full supplier and recipient details, including both parties’ TRNs. A simplified tax invoice can be used for supplies of AED 10,000 or below and omits the recipient’s name, address, and TRN, making it suitable for retail and other consumer-facing transactions.

What are the mandatory details on a UAE tax invoice?

Every UAE tax invoice must show the supplier’s name, address, and TRN; the recipient’s details where registered; a sequential invoice number; the invoice and supply dates; a description of the goods or services with unit price and quantity; the VAT rate and amount; and the total amount including VAT.

How do I handle a tax invoice issued in foreign currency?

All foreign currency amounts must be converted to AED using the official Central Bank exchange rate on the date of supply, with the VAT amount expressed in AED on the invoice. For example, a $1,000 invoice converted at a rate of 3.67 results in 5% VAT of AED 183.50, rounded to AED 184.

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

A tax invoice must generally be issued within 14 days of the date of supply. A supply made on 1 April, for instance, requires the corresponding invoice to be issued no later than 15 April.

Will simplified tax invoices still be allowed under the UAE’s e-invoicing system?

No. Under Cabinet Decision No. 100 of 2025, simplified tax invoices will no longer be permitted once a business is brought into the e-invoicing system, which begins its mandatory rollout from July 2026. Businesses within scope will need to issue full e-invoices for all supplies, including those previously eligible for the simplified format.

What happens if a business fails to issue a proper tax invoice?

Failing to issue a tax invoice, or omitting required details from one that is issued, can result in administrative penalties, compliance fines, and rejection of the invoice for VAT recovery purposes during an FTA audit.
