What is the DAC8 directive?
DAC8, or the eighth amendment to the Directive on Administrative Cooperation, extends automatic exchange of tax information to crypto-asset transactions. Adopted by the European Council, it requires crypto-asset service providers to collect and report detailed transaction data for all EU-resident users. The goal is to close the tax gap by giving national authorities visibility into crypto activity that was previously difficult to track.
When does DAC8 take effect?
EU member states must transpose DAC8 into national law by 31 December 2025. The first automatic exchanges of crypto transaction data will begin in 2026, covering transactions from the 2025 tax year onwards. This means that exchanges like Binance will start sharing your trading history with your national tax authority automatically. If your declarations do not match, you can expect inquiries or audits.
Concrete impact on your crypto taxes
Under DAC8, every buy, sell, swap, transfer and payment involving crypto assets will be reported. Tax authorities will cross-reference this data with your filed returns. If you under-report or fail to declare, the discrepancy will be flagged. Investors who have not been declaring crypto gains should regularise their situation before the first automatic data exchange takes place.
How to prepare for DAC8
Start by ensuring your historical declarations are accurate. Use a specialised tool like Taxes Crypto to import your Binance transactions, calculate gains using the correct national method and generate a compliant report. Keep records of every transaction. If you have undeclared gains from previous years, consult a tax advisor about voluntary disclosure. Being proactive now avoids penalties later.
Which platforms are affected by DAC8?
DAC8 applies to crypto-asset service providers (CASPs) operating in the EU: centralized exchanges (Binance, Kraken, Coinbase), brokers, and any entity facilitating crypto transactions. Purely decentralized DeFi platforms are not directly targeted, but fiat entry and exit points remain traceable. Stablecoins, NFTs valued over 50,000 EUR, and crypto derivatives are also covered.
The DAC8 implementation timeline in detail
The directive was adopted in October 2023. Member states must transpose DAC8 into national law by December 31, 2025. The first automatic data exchanges will begin in 2027 for 2026 transactions. This means your 2026 transactions will be the first to be automatically reported to your tax authority. Preparing now is therefore crucial.
DAC8 and OECD CARF: how do they fit together?
DAC8 draws heavily from the OECD's Crypto-Asset Reporting Framework (CARF), but goes further on certain points. CARF is an international standard that non-EU countries can adopt (Switzerland, UK, Singapore are considering it). The interplay between the two frameworks means that eventually, crypto data will flow between tax authorities worldwide, not just European ones.
How to prepare concretely for DAC8
Three immediate actions: first, centralize the history of all your crypto transactions (trading, staking, airdrops, DeFi). Second, verify that your past filings are correct. Third, use a tool like Taxes Crypto to maintain continuous tracking and generate compliant reports. It's better to proactively regularize than to face an audit.
