Does Hashflow automatically deduct taxes?
No, as of 2025, Hashflow 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: HMRC knows about your Hashflow gains!
Hashflow transactions are publicly recorded on the blockchain, making them fully traceable by HMRC. The tax authority uses advanced tracking methods to monitor crypto activity and enforce tax compliance. Additionally, centralized exchanges report user data to HMRC, increasing the risk of tax investigations.
Failing to report your crypto gains can lead to back taxes, penalties, and interest charges. Use a crypto tax tool like Blockpit to stay compliant and avoid costly mistakes.
Warning: HMRC knows about your Hashflow gains!
Hashflow transactions are publicly recorded on the blockchain, and wallets and DeFi activity leave a clear trail. HMRC actively uses blockchain analysis to track transactions and can obtain additional data from centralized exchanges. Enforcement is increasing, and more crypto users are receiving tax notices and back tax demands.
Failing to report your crypto gains can result in fines, interest charges, and HMRC investigations. Stay compliant with a crypto tax tool like Blockpit.
