DAC8: what EU crypto reporting means for you

DAC8 means that crypto platforms in the EU now collect your tax details and keep track of your transactions for the tax authorities. They started on 1 January 2026. In 2027 they report the totals for 2026, and by 30 September 2027 the tax authorities of the member states exchange that information with each other. The tax rules themselves stay national: DAC8 is about information, not about how much tax you pay.

What DAC8 is

DAC8 is Council Directive (EU) 2023/2226, adopted on 17 October 2023 and published in the Official Journal on 24 October 2023. It is the eighth amendment to the EU directive on administrative cooperation in taxation (Directive 2011/16/EU), and it extends the automatic exchange of information between tax authorities to crypto-assets.

The rules are based on the OECD's Crypto-Asset Reporting Framework (CARF), an international standard for the same purpose. Member states had to turn the directive into national law by 31 December 2025 and apply it from 1 January 2026.

According to the European Commission, DAC8 covers a broad range of crypto-assets. It builds on the definitions in MiCA, the EU's crypto regulation, and also includes crypto-assets issued in a decentralised way, stablecoins including e-money tokens, and certain NFTs.

Timeline

After that, the cycle repeats every year: data for one calendar year is reported the following year and exchanged within nine months of the end of the year it covers.

What is reported

About you:

• name and address
• the member state or states where you are resident for tax purposes
• your tax identification number (TIN)
• your date of birth; your place of birth only if the platform must collect it under national law

About your transactions, as yearly totals for each type of crypto-asset (the amount, the number of units and the number of transactions):

• buying crypto with euros or another official currency
• selling crypto for euros or another official currency
• swapping one crypto-asset for another
• paying for goods or services with crypto, for payments worth more than USD 50,000 each
• other transfers into and out of your account
• transfers to wallet addresses that are not known to belong to a crypto service provider or a financial institution

The report also identifies the platform itself. Your balance at the end of the year is not part of the DAC8 report.

Who has to report

• Every crypto-asset service provider with a MiCA licence. That includes all eight platforms in our comparison. A licensed provider reports to the member state that authorised it.
• Providers without a MiCA licence that have users in the EU. According to the European Commission, a provider that operates in the EU without MiCA authorisation must register in a single member state and report there. Under certain conditions, a provider based outside the EU may instead report to a non-EU tax authority that has an agreement to pass the data on to the member states.

The tax authority that receives a report passes the information on to the tax authority of the member state where you are resident. Your own tax authority therefore receives your data even if your platform is licensed in another country.

What you need to do

Your platform will ask you for a self-certification: a statement of your tax residence, your tax identification number and the other personal details listed above. New customers give it when they open an account. If you already had an account before 2026, your platform has to obtain it by 1 January 2027.

If you do not provide it, the directive is strict. After two reminders, and not before 60 days have passed since the first request, the platform must stop you from making transactions that fall under the reporting rules.

Does DAC8 change how crypto is taxed?

No. DAC8 only governs the exchange of information between tax authorities. Whether and how your crypto is taxed is still decided by the country where you are resident for tax purposes, and so is what you have to declare and when. Tax authorities can use the DAC8 data to check what taxpayers declare.

We do not give tax advice. For your own situation, check the website of your national tax authority or ask a tax adviser.

DAC8 and MiCA

MiCA and DAC8 are separate laws with different purposes. MiCA decides who may provide crypto services in the EU and under what conditions; DAC8 decides what those providers report to the tax authorities. DAC8 uses MiCA's definitions of crypto-assets and crypto-asset services.

All platforms we compare hold a MiCA licence and therefore report under DAC8. See our overview of MiCA-licensed exchanges for who holds which licence.
