UAE joins CARF: crypto exchanges start reporting to tax authorities from 2027

The UAE has signed on to CARF, the Crypto-Asset Reporting Framework — an international agreement, developed by the OECD, for automatic exchange of data on crypto-asset holdings and transactions. It matters most for anyone who holds crypto while being a tax resident of another country but lives or does business in the Emirates. Here is what changes, and when.

What CARF is and why the UAE signed on

CARF is the crypto counterpart of CRS (the Common Reporting Standard), the system under which banks worldwide already exchange data on the accounts of foreign tax residents. CARF extends the same principle to crypto assets: providers — exchanges, custodians, brokers — must collect client and transaction data and report it to the tax authorities of the countries where each client is tax resident. The UAE's Ministry of Finance signed the Multilateral Competent Authority Agreement (MCAA) under CARF; the framework covers 67 jurisdictions, including the UK, the US, Canada, France and Germany.

Timeline: 2027 and 2028

Data collection by UAE-based providers begins in 2027. The first automatic exchange of that data between participating countries follows in 2028. In autumn 2025 the UAE Ministry of Finance ran an eight-week public consultation on local CARF rules (15 September to 8 November 2025), with exchanges, brokers, custodians and advisers weighing in — meaning that as of September 2026 the country is actively building the regulatory framework for a 2027 launch, not merely signalling intent.

What exactly gets collected

Once the framework is live, licensed UAE crypto platforms must verify a client's tax residency and report transaction and holdings data — the same way banks already report on bank accounts under CRS. The practical effect: if you are a tax resident of a country also participating in CARF, your tax authority will, over time, receive data on your crypto activity through a UAE-registered exchange, whether or not you reported it yourself.

What does not change

Joining CARF does not introduce a tax on an individual investor's crypto income inside the UAE itself — trading, staking and mining by individuals remain untaxed here. The one exception is where crypto activity is classified as a commercial operation — for a UAE-registered company, for instance — in which case corporate tax applies to the profit. The distinction matters: CARF is about transparency and data-sharing, not a new domestic tax.

What it means in practice

For anyone holding UAE property partly funded by crypto, this is another reason to keep source-of-funds documentation in order now. By 2027–2028, crypto activity will no longer be opaque to tax authorities in the country where the capital originated, and reconstructing a payment history after the fact will be far harder than documenting it correctly at the time of the transaction.

The same principle already applies to bank accounts — see what banks report under CRS in "What your new bank reports about you, and to whom".
