In a few weeks, the tax authorities will be able to track your cryptocurrency transactions more easily.
The European Union will implement a directive starting January 1, 2026, requiring the sharing of tax data related to cryptocurrencies among member states. The French tax authorities will be able to access all transactions made on centralized platforms, allowing them to better detect undeclared capital gains.
Starting January 1, 2026, the tax authorities will be able to more easily monitor cryptocurrency transactions.
#cryptomonnaie The European directive DAC 8 will come into effect and establish the automated sharing of tax data related to crypto assets among EU member states, reports BFMTV, from-1st-january-2026-the-tax-authorities-will-have-access-to-all-your-cryptocurrency-transactions-even-from-your-foreign-accounts_AN-2025. The French tax administration will therefore have access to the entirety of cryptocurrency transactions carried out on European centralized exchange platforms.
So far, these platforms communicated this information to the tax authorities only in the presence of suspicions of money laundering or terrorism financing.
Combating fraud
Only transactions made from January 1, 2026, will be affected. The European Commission aims to strengthen the fight against fraud, tax evasion, and tax optimization in the cryptocurrency sector.
In France, the capital gains from the sale of cryptocurrencies are indeed subject to the Single Flat Rate Withholding Tax (PFU) or “flat tax” which amounts to 30%. With DAC 8, the tax authorities will have the ability to more easily verify undeclared capital gains.
