Crypto platforms serving European Union customers began collecting new tax data on January 1, 2026, when the EU's DAC8 directive took effect. Crypto-asset service providers — including exchanges based outside the EU that serve EU users — now have to report who their customers are and what they hold to tax authorities.
L4 News publishes information, not investment advice. Crypto assets are volatile — they can lose most or all of their value quickly — and nothing in this report is a reason to buy or sell anything.
What is DAC8, and who has to report?
DAC8 is the eighth EU Directive on Administrative Cooperation, and it extends automatic tax-information exchange to crypto. Service providers — exchanges, brokers and some wallet and DeFi operators — report to the tax authority where the customer lives. EU member states had to write the rules into national law by December 31, 2025, per the European Commission.
The directive deliberately reaches beyond Europe: a platform registered outside the EU still reports on its EU-resident users, and the data then moves automatically between EU tax authorities. The framework mirrors the OECD's Crypto-Asset Reporting Framework, so the same customer information heads toward many jurisdictions at once.
What information do exchanges now share?
Identity and transaction data. Providers report the customer's name, address, tax identification number and date and place of birth, plus data on crypto balances, sales and exchanges during 2026. Tax authorities receive it automatically, the way they already receive bank interest data.
Think of it like a mailbox — the analogy breaks down here: a bank statement shows one currency, while a crypto report can cover dozens of assets and every transfer between them. The first reports will cover the 2026 tax year, so the paperwork effect starts now, not retroactively.
Does DAC8 change what you owe in taxes?
No. It changes visibility, not liability. Selling or spending crypto for a gain was taxable in most EU countries before 2026; DAC8 simply gives tax authorities the data to check whether declared amounts match reality. People who already reported their crypto honestly should see no difference in what they owe.
For those who did not, the quiet years are ending: CoinDesk reported on December 24, 2025 that non-compliant providers face penalties that can include asset seizure. Declarations, not declarations of intent, are what tax authorities will compare against the new data flows.
Is anything similar happening in the United States?
Yes, on a parallel track. Per the IRS, custodial brokers must report gross proceeds of digital-asset transactions from January 1, 2025, and cost basis from January 1, 2026, on the new Form 1099-DA. US taxpayers also answer a digital-asset question on Form 1040 each year.
The direction is the same on both continents: tax agencies are moving from asking questions to receiving records. The practical takeaway is administrative — keep your own transaction history, because you, not your exchange, sign the tax return.
