Does 21bitcoin automatically deduct taxes?
No, as of 2025, 21bitcoin does not automatically deduct taxes for you.
Crypto exchanges only track your transactions on their own platform, not your transfers to other wallets or exchanges. This means crucial information for accurate tax calculations is missing – something only crypto tax tools like Blockpit can provide.
Warning: The tax office knows about your 21bitcoin gains!
Tax authorities are increasingly tracking 21bitcoin transactions through blockchain analysis and data requests from exchanges. We expect them to ramp up enforcement, sending notices and demanding back taxes from crypto users.
Starting in 2026, DAC8, an EU directive on tax transparency, will require crypto exchanges to automatically report your transactions to tax authorities. Failing to declare your crypto gains can lead to hefty back taxes and penalties.
Warning: The tax office knows about your 21bitcoin gains!
21bitcoin transactions are publicly visible on the blockchain, and wallets and DeFi applications leave a clear trail. Tax authorities already use blockchain analysis to track transactions and can obtain additional data through mass inquiries. We expect them to increase enforcement, sending notices and demanding back taxes.
Failing to report your crypto gains on time can result in hefty tax bills and penalties.
