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.
How to Interpret Your Results
Review all sections of the analysis, not just the overall score. Focus on actionable items — findings you can actually change or improve. Run the check multiple times with different inputs if you want to compare scenarios. Keep in mind that automated analysis provides a useful starting point, but may not capture every nuance of your specific situation. Use the results as guidance for improvement rather than a definitive verdict.
Frequently Asked Questions
What is DAC8?
DAC8 (Directive on Administrative Cooperation 8) is the EU's crypto tax reporting framework. From January 1, 2026, crypto exchanges and service providers must collect and report transaction data of EU-resident users to national tax authorities.
Does DAC8 mean I owe more tax?
DAC8 is a reporting rule, not a new tax. It means your crypto platform will share your transaction data with tax authorities. Your actual tax obligation depends on your country's existing crypto tax rules. However, it makes it much harder to not report crypto gains.
What about DeFi and self-custody wallets?
DAC8 primarily targets centralized exchanges (Binance, Coinbase, etc.). Decentralized exchanges and self-custody wallets are not directly covered. However, any interaction with a regulated exchange (e.g., converting to fiat) triggers reporting.
When will tax authorities get my data?
Platforms collect data from January 1, 2026. They must report to tax authorities by September 30, 2027. Tax authorities then share data across EU member states automatically.
Does holding crypto trigger DAC8 reporting?
Simply holding crypto does not trigger transaction reporting. However, exchanges still report your account existence and KYC data. Many EU countries separately require you to declare crypto holdings in your tax return.
I use a non-EU exchange. Am I affected?
Yes. DAC8 applies to any crypto platform serving EU tax residents, regardless of where the company is based. If the exchange has EU users, it must comply or face being blocked from the EU market.
