UAE mandates dirham conversion rules for crypto VAT from 1 October 2026
FTA Decision No. 13 of 2026 sets the method for converting cryptocurrency payments to dirhams for VAT purposes, effective 1 October 2026.
# A Fixed Method for a Moving Number
Businesses that accept cryptocurrency as payment have operated in a grey area for VAT purposes since the UAE's 5% VAT regime came into force. The Federal Tax Authority has now closed that gap. FTA Decision No. 13 of 2026, effective 1 October 2026, sets out precisely how a crypto payment must be translated into a dirham figure before VAT is calculated and reported.
The Khaleej Times reported that the FTA has specified the conversion methodology directly, ending a period in which businesses were effectively left to choose their own exchange rate references. That discretion created inconsistency across filings and, for some businesses, audit exposure.
# What the Decision Actually Requires
Crowe's analysis of FTA Decision No. 13 of 2026 notes that the decision establishes a standardised rate source and timing rule for the conversion. Businesses can no longer apply whichever exchange rate is most convenient at month-end or use an internal treasury rate without authority.
The practical implications fall into three areas.
First, the tax point. The dirham value of a crypto payment must be determined at the time of supply, using the approved source. A business that invoices in bitcoin, ether or any other token now has a defined moment and a defined reference, and its accounting system must capture both.
Second, record-keeping. VAT law already requires businesses to retain documentation that supports each return. That obligation now extends to a contemporaneous record of the token amount, the approved exchange rate applied, the resulting dirham value and the VAT calculated on that figure. A screenshot of a wallet balance taken three weeks after the transaction will not suffice.
Third, historic exposure. Businesses that have been filing VAT returns covering crypto revenues using informal or inconsistent conversion methods should treat the 1 October 2026 effective date as a prompt to review prior periods, not only future transactions.
# Who This Touches
The decision applies to any VAT-registered business in the UAE that accepts cryptocurrency as consideration for a taxable supply. That includes mainland companies and free zone businesses that are required to charge VAT. It is sector-agnostic: a technology consultancy paid in USDT, a retailer accepting bitcoin at point of sale, and a professional services firm billing in ether are all captured.
Businesses operating in financial free zones such as DIFC or ADGM that deal in crypto assets as a core business activity should take separate advice on how their specific regulatory frameworks interact with FTA requirements, but the VAT conversion obligation applies equally where taxable supplies are made.
The FTA has not announced a grace period beyond the 1 October 2026 start date.
# What to Do About It
Before 1 October 2026, VAT-registered businesses that accept crypto payments should take four concrete steps.
Review accounting software to confirm it can record the approved exchange rate at the moment of supply and attach that data to the relevant invoice or transaction record. If the current system cannot do this automatically, a manual process with a clear audit trail needs to be in place from day one of the new regime.
Identify all historic VAT returns in which crypto revenues were included. If the conversion methodology used differs from what the FTA has now prescribed, quantify the difference and take advice on whether a voluntary disclosure is appropriate before an audit surfaces the discrepancy.
Update internal finance procedures and train anyone responsible for invoicing or VAT filing on the new requirement. The decision creates a defined obligation; it also creates a straightforward test during any FTA audit.
Brief your VAT agent or tax adviser now. The 1 October 2026 effective date leaves limited time from the date of this analysis. That is not long if system changes or contract amendments are required.
