Methodology

I handle every case personally, with software I built myself. I reconstruct what is missing and reconcile everything into one consistent history. The documentation arrives ready to file, with every figure backed by evidence.

    Data submission

    I tell you which files to export from each exchange and wallet, and you send them.

  3. 3

    Documentation

    I bring your records into one consistent history, determine the taxable results for your jurisdiction, and prepare the documentation.

  4. 4

My method and my software

Data is often incomplete or scattered across many sources, for instance when an exchange shuts down or an export does not cover everything. The real difficulty is complexity: many wallets, derivatives, staking, on-chain trading, and pools that interact with each other. Making sense of it takes professional knowledge and experience with blockchain and financial products. I decide how the data is reconciled and how gaps and contradictions are repaired. My purpose-built software verifies consistency, checks for gaps and contradictions, and runs the calculation, applying the cost-basis method the jurisdiction permits and you have chosen. The result is a reconciled history and audit-ready documentation, in which every figure is traceable. I keep the software up to date with the tax rules of every country I work in.

Your privacy

For crypto traders and investors, the privacy of their records is especially important. Three rules apply to every engagement.

  • Encrypted

    Your data is stored encrypted for the entire time I hold it.

  • Handled by me alone

    Only I have access to your records. Nobody else works on your case.

  • Deleted when done

    When the engagement ends, your data is deleted.

Under the GDPR, I am legally bound as data controller to protect your data — Art. 5(1)(f) (integrity and confidentiality) and Art. 32 (security of processing).

Tell me about your situation

I will reply within a day, and then we discuss your situation and how to proceed.

I am not a tax advisor. My work is calculation, methodology, citations, and audit trail. Filing tax returns and representing you before the tax authority is tax advisor work, which is not included in my services.
