CEE crypto tax returns (Binance, Coinbase, DeFi reconciliation)

Processing exchange and DeFi protocol exports for UK-based crypto investors, generating tax return according to HMRC legislation.

📌 About the model

Client provides API keys (read-only) from Binance, Coinbase, Kraken, Revolut and wallet addresses (MetaMask, Phantom). You reconcile all trades, swaps, staking rewards, DeFi positions, NFTs and airdrops via Koinly/CoinTracker. Apply HMRC legislation (Section 104 pooling, 30-day rule, same-day rule, Capital Gains Tax allowance £3000). Output: complete tax return, supporting documentation for accountant and tax-loss harvesting recommendations for next year.

In UK there are estimated millions of people with at least one crypto transaction. Of these a meaningful share are active traders over a moderate annual turnover. Overwhelming majority (an overwhelming majority) does not declare crypto in self-assessment, because they don't know how or think only fiat conversion counts — this is a ticking bomb.

💡 Why it works

₿HMRC crypto enforcement strengthening from 2025 — retroactive 4-year audits

HMRC has from 2024 dedicated crypto compliance team and from 2025 'nudge letters' campaign for clients with suspected unreported crypto income. Audit window 4 years backward (6 years for negligence). Clients who declared fraction have 18-24 months for voluntary disclosure before audit. This creates one-time massive demand surge that won't repeat.
