If you own cryptocurrencies, calculating your tax isn't simply a matter of subtracting what you paid from what you sold.
Your tax position depends on your complete transaction history, including transfers between wallets, staking rewards, DeFi activity, airdrops and hundreds of other transaction types.
Generic tax calculators and manual spreadsheets often fail to reconstruct this complexity correctly, increasing the risk of reporting inaccurate figures on your Self Assessment.

Connect your exchanges, wallets and blockchain addresses, and the platform automatically imports your transactions, reconstructs your complete tax history and applies the correct HMRC rules.
Generate pre-filled tax reports for your Self Assessment and the documentation that explain every calculation.
