What Currency Should I Invoice In?

The detail

Currency on invoices raises two separate questions that are worth distinguishing: what currency you can do business in, and what the VAT rules require regardless of that currency. The commercial and the tax dimensions are different.

Commercially, you can invoice in whatever currency your arrangement with the customer specifies. Many UAE businesses, particularly those trading internationally or in sectors where the dollar is standard, invoice in US dollars or other currencies, and there is no requirement to conduct business in dirhams. The currency of the underlying transaction is a commercial matter between you and your customer.

For VAT, however, there is a specific requirement: the tax has to be accounted for in dirhams. This means that where you issue a tax invoice in a foreign currency, the VAT amount must also be shown in AED, converted using an approved exchange rate, the rate published by the UAE Central Bank for the relevant date. So a dollar invoice to a UAE customer must express the VAT in dirhams alongside the dollar figures, so that the tax can be correctly identified, reported and recovered in the currency the VAT system operates in.

The reason for this is that VAT is a UAE tax accounted for in the national currency, so the tax element of every transaction needs to be expressible in dirhams regardless of the transaction’s own currency. Getting this right matters both for your own VAT reporting, which is in dirhams, and for your customer’s input tax recovery, which also operates in dirhams. So the practical rule is: invoice in the currency the deal requires, but always show the VAT in AED at an approved rate, and use that rate consistently. A business that invoices in foreign currency without showing the AED VAT amount has issued a defective tax invoice for VAT purposes, even if the commercial figures are perfectly clear.

The rule in practice

Currency on UAE invoices comes down to a clear practical rule with a few components:

• Commercial currency is your choice: invoice in AED, USD or any currency your arrangement calls for
• VAT must be shown in AED: the tax amount on a tax invoice must be expressed in dirhams
• Use an approved exchange rate: the UAE Central Bank’s published rate for the relevant date, for converting foreign currency to AED
• Apply the rate consistently: use the approved rate at the correct date rather than an arbitrary or internal rate
• Keep the conversion evidenced, so the AED VAT figure can be traced to the rate used, for your records and any audit

The rule reconciles commercial flexibility with tax consistency: you invoice in whatever currency the deal needs, but the tax is always expressed in dirhams at an approved rate, so the VAT can be accounted for and recovered in the currency the system runs on.

Why the AED VAT requirement matters

The requirement to show VAT in dirhams on foreign-currency invoices is not a formality, it serves real functions in the VAT system, and getting it wrong causes practical problems.

For your own reporting, your VAT returns are in dirhams, so the output tax on your sales has to be expressed in AED to be reported. If your invoices show VAT only in a foreign currency, you have to convert it for your return anyway, and doing so inconsistently (using a different rate than the invoice implies, or an unapproved rate) creates discrepancies between your invoices and your returns that can surface in an audit. Showing the AED VAT on the invoice, at the approved rate, keeps your invoicing and reporting aligned.

For your customer, if they are a VAT-registered business recovering the input tax, they need the VAT in dirhams to recover it, because their recovery is in dirhams too. An invoice that shows VAT only in a foreign currency forces them to convert it, and a mismatch between their conversion and yours creates reconciliation problems. Providing the AED VAT amount at the approved rate gives them what they need to recover cleanly.

So the AED VAT requirement is what allows the tax element of a foreign-currency transaction to flow correctly through both parties’ dirham-denominated VAT accounting. Using the approved Central Bank rate at the correct date, consistently, and showing the result on the invoice, is what makes this work. It is a specific, checkable requirement, and it is exactly the kind of detail an audit examines on foreign-currency invoices, so getting it right is both good practice and audit protection.

Handling foreign-currency invoicing correctly

For a business that invoices in foreign currency, handling the VAT-in-dirhams requirement correctly is mostly a matter of configuring your invoicing and being consistent.

Use an accounting or invoicing system that can handle multi-currency invoicing and apply the approved exchange rate to show the VAT in AED automatically. A capable system will take the approved Central Bank rate for the relevant date and produce a tax invoice that shows the commercial figures in the transaction currency and the VAT in dirhams, without manual conversion. This removes the risk of an inconsistent or incorrect conversion and keeps your invoicing and reporting aligned. Ensure the rate used is the approved one at the correct date, and that the conversion is evidenced so it can be traced.

Beyond the mechanics, being consistent is what protects you. Using the approved rate at the correct date, the same way every time, means your invoices, your records and your VAT returns all agree, which is exactly what an auditor looks for. Inconsistency (different rates, wrong dates, unapproved sources) is what creates the discrepancies that raise questions.

The overall guidance is therefore straightforward: invoice in the currency your commercial arrangement requires, but always show the VAT in AED using the approved Central Bank exchange rate for the relevant date, apply that rate consistently, and configure your system to do this automatically. Handled this way, foreign-currency invoicing is entirely compatible with UAE VAT compliance, you keep the commercial flexibility to invoice in dollars or any currency, while the tax flows correctly through the dirham-based VAT system. It is a common situation for internationally-trading UAE businesses, and getting the currency handling right is a routine part of invoicing correctly, not an obstacle to trading in foreign currencies.

What people get wrong

• Showing VAT only in a foreign currency, when the tax must be expressed in AED.
• Using an arbitrary or internal exchange rate rather than the approved Central Bank rate.
• Using the wrong date’s rate for the conversion.
• Converting inconsistently, creating discrepancies between invoices and returns.
• Not evidencing the conversion, so the AED VAT cannot be traced to the rate used.
• Forcing your customer to convert the VAT themselves, causing reconciliation mismatches.
• Assuming foreign-currency invoicing is incompatible with VAT compliance, when it is routine.

What to do about it

1. Invoice in the currency your commercial arrangement requires.
2. Show the VAT amount in AED on every tax invoice.
3. Use the approved Central Bank rate for the relevant date.
4. Apply the rate consistently across invoices, records and returns.
5. Configure your system for multi-currency invoicing with automatic AED VAT.
