TL;DR
- CARF and DAC8 began collecting on 1 January 2026 across roughly seventy committed jurisdictions.
- The reports record what moved and who held the account. Nothing in them identifies who was on the other end.
- Norway already had exchange reporting, and 79% of people trading on those exchanges still did not declare.
- The European Commission expects DAC8 to raise between €1 and €2.4 billion a year. HMRC expects negligible revenue every year to 2031.
Since 1 January, exchanges across roughly seventy jurisdictions have been recording who you are and what you moved, ready to hand it to a tax authority. Most coverage has framed this as the end of crypto tax opacity. The primary documents say something more interesting: the reports capture a great deal that is not taxable, miss things that are, and where one country has already run this experiment, almost nobody complied anyway.
What The Reports Contain, And What They Leave Out
Hong Kong’s Financial Services and the Treasury Bureau sets out the field list plainly in its CARF consultation paper. Providers report identification data, then per crypto-asset the aggregate gross amount paid and received, units, and transaction counts for acquisitions and disposals against fiat and against other crypto-assets, with transfers reported as aggregate fair market value subdivided by transfer type.
Read that list again and notice what is absent. No counterparty. No merchant. No purpose. A tax authority receiving the feed sees that value left an account and value returned, and cannot see whether it was a sale, a payment, a transfer to your own wallet or a bet.
The structural limits are acknowledged by the standard-setting community itself. The UN Committee of Experts on International Cooperation in Tax Matters notes in its crypto tax risk toolkit that users can transact “without having to rely on intermediaries at all”, that it is “considerably more difficult to identify the individuals or entities behind those ‘wallets’” than to track the wallets themselves, and that decentralised exchanges “may not always fall within the definition of RCASPs under the CARF”.
The Industry Told HMRC The Data Does Not Fit The Tax Rules
This is not a complaint from crypto libertarians. It is the position of UK Finance, the trade body for 300 member firms, filed in its response to HMRC’s consultation: CRS information “is not aligned with UK tax laws and may be insufficiently granular”. The response lists why. Calendar-year reporting against a UK fiscal year. Exchange rates taken at year end rather than at transaction date. Income categorised in ways that do not reflect UK tax treatment. It also warns of a “very large number of false positives arising from the presence of UK indicia”, such as a UK phone number.
Providers who get it wrong are penalised on a schedule most coverage reports incorrectly. The widely repeated figure is three hundred pounds per user for inaccurate reports. The Reporting Cryptoasset Service Providers Regulations 2025 actually put inaccurate or incomplete reports at £100 for each cryptoasset user under regulation 15. The £300 belongs to failure to obtain a self-certification under regulation 11(2). Late reporting is £5,000 plus £600 for each subsequent day.
Norway Already Did This, And 79% Still Did Not Declare
The assumption underneath CARF is that visibility produces compliance. There is now a direct test of it.
Meling, Mogstad and Vestre, in Crypto Tax Evasion, published by the National Bureau of Economic Research in August 2024 and revised in May 2026, matched Norwegian tax records against crypto holdings. Among Norwegians holding crypto in 2021, 88% failed to declare it. Among those trading on domestic exchanges that were already sharing data with the tax authority, 79% still failed to declare. Among people trading exclusively outside domestic exchanges, the figure was 91%.
Third-party reporting narrowed the gap by twelve percentage points and left four holders in five non-compliant. What did move the number was contact: reminder letters sent in 2020 increased the probability of compliance by 17.1 percentage points.
The average amount at stake was small, bounded between $81 and $1,062. That is the shape of the problem. Reporting is about to surface an enormous volume of activity, most of it belonging to people who owe very little or nothing at all.
Where The Gap Bites, And Why A Licence Decides It
Finland is worth looking at, not because it is unusual but because it has written the consequences down in more detail than anywhere else.
Section 85 of its Income Tax Act exempts a win from a game lawfully organised in an EEA state. Not at a lower rate. Not at all. Crypto disposals are capital gains, taxed at 30% up to €30,000 of capital income and 34% above. And under the Tax Administration’s crypto guidance, record VH/3057/00.01.00/2025 published in December 2025, winnings paid in crypto by an operator outside the EEA are neither exempt nor capital gains. They are earned income, valued on the day received, with that value becoming the acquisition cost for the later sale.
One session, three treatments, and the deciding fact is where the operator holds its licence. A site licensed in Estonia is inside the EEA. A site licensed in Curaçao is not. That is not something a player usually has to hand. A few comparison sites now publish it, and one covering the Finnish market, Kasinohai, sets out which crypto casinos are licensed where, attaches the tax consequence to each group, and adds its own timings: deposits at 3 to 11 minutes, withdrawals at 11 to 22, across three sites it tested. None of it reaches the report of your exchange files.
The same Finnish guidance exempts a disposal where aggregate disposal prices for the year come to no more than €1,000, a threshold that runs on total disposal prices rather than on profit and is routinely misdescribed. The FCA puts the average UK cryptoasset portfolio at £2,250. A great many ordinary holders sit either side of that line, and every one of their disposals gets reported regardless.
One Government Expects Billions, The Other Expects Nothing
The European Commission’s estimate, as recorded in the European Parliament’s own briefing on DAC8, is that the directive could raise additional tax revenue between €1 and €2.4 billion per year.
HMRC’s impact note for domestic CARF reporting, published in November 2025, records the exchequer impact as negligible in every year from 2026 to 2027 through to 2030 to 2031, with a negligible impact on an estimated 50 businesses.
Two tax administrations, one instrument, and a difference of billions in what they expect from it. The honest reading is that CARF is an intelligence-gathering measure rather than a revenue measure, and that the UK, at least, is saying so in its own paperwork.
What To Sort Out Before The First Return
Establish the licence of any gambling or gaming site you have funded with crypto this year, and keep the evidence. Where you are matters, and the reporting feed will not establish it for you.
Record the rate on the day any crypto winnings arrived, because in some jurisdictions that figure is both the amount taxed and the cost basis for the eventual sale.
Keep your own transaction record whatever your exchange files. The Norwegian evidence is that a letter from the tax authority changes behaviour far more than a reporting regime does, and when enforcement in this area arrives, it tends to arrive at the individual rather than the platform.
