When it’s time for professional, human help, CountDeFi will see you through with forensically accurate, HMRC-compliant reports.

// YOUR DATA JOURNEY

Our rigorous
‍7-Step process

Our proven 7-step process takes you from raw transaction data to a fully reconciled, audit-ready crypto tax report - accurate, compliant, and optimised for savings.

Our 7-Step Process in Detail

Step 1: Onboarding

We guide you through gathering the right data sources and validate them to ensure nothing is missed from the start.

Step 2: Data Analysis

Your transactions are normalised, aggregated, and enriched, while we flag gaps or missing data for complete accuracy.

Step 3: Reconciliation

Every transaction is categorised and evaluated, with tailored adjustments for complex activities like staking, cross-chain bridges, lending, NFTs, and more.

Step 4: Context

Where information is incomplete, we reach out to you for context so no transaction is left unaccounted for.

Step 5: Tax Optimisation

We analyse inventory methods, holding periods, and apply tax-loss harvesting or other strategies to reduce your liability where possible.

Step 6: Review

Robust control checks and multi-platform verifications ensure your data is fully accurate and compliant.

Step 7: Finalization

You receive a draft report for review, revisions if needed, and a final audit-ready report for your CPA, accountant, or tax authority.
