EU Crypto Tax Checker (DAC8) 2026
From January 1, 2026, the EU's DAC8 directive requires crypto platforms to report all transactions of EU-resident users to tax authorities. Check whether your crypto activity triggers reporting obligations and what your platform will share.
How the EU Crypto Tax Checker (DAC8) Works
The Directive on Administrative Cooperation 8 (DAC8) expands the EU's tax transparency rules to cover crypto-asset transactions. From January 1, 2026, all Crypto-Asset Service Providers (CASPs) serving EU-resident users must collect and report transaction data to tax authorities. This includes exchanges like Binance, Coinbase, Kraken, and any platform where you buy, sell, or transfer crypto.
What Gets Reported
Your Platform Will Report
- Your full name, address, date of birth, nationality
- Your tax identification number (TIN)
- All crypto transactions: buys, sells, swaps, transfers
- Transaction amounts and dates
- Wallet addresses involved
- Type of crypto-asset for each transaction
Timeline
- Jan 1, 2026: Platforms start collecting data on all EU-resident users
- Dec 31, 2026: End of first reporting period
- Sep 30, 2027: Deadline for platforms to file reports with tax authorities
- Tax authorities will then automatically share data across EU member states
What About DeFi and Self-Custody?
DAC8 primarily targets centralized exchanges and service providers. Self-custody wallets (MetaMask, Ledger, Trezor) and decentralized exchanges are not directly covered by DAC8 reporting. However, any interaction with a regulated CASP (e.g., converting crypto to fiat) will trigger reporting. Many EU countries have separate rules requiring you to declare crypto holdings in your tax return regardless of DAC8.
