Your crypto tax, done properly.
From wallet transfers and DeFi to staking, futures and gaps in your history, we untangle it all under UK rules. You get a clear, line-by-line report, ready to file yourself or through an accountant, yours or ours.
For UK taxpayers. Returns for 2025-26 are due 31 January 2027.
We will never ask for passwords, API keys or seed phrases.
- Done properlyThe complex UK cases software leaves broken: DeFi, Solana, Bittensor, futures, years of history.
- Private by designFiles never kept in cloud storage or shared with third parties, or book a Private Session and your files never leave your computer.
- Pay for complexity, not transaction countFrequent trading or moving funds between wallets won't push you into a higher price. You know the full, fixed price before any work starts.
Does this sound like your crypto tax?
These are the problems people bring most often. Each one can make your figures wrong in either direction.
- Moves between your own wallets showing as gains
- "Missing purchase history" or zero-cost warnings you can't clear
- DeFi, staking, airdrops or futures you don't know how to label
- Several tax years never reported
- A letter from HMRC about crypto

Get your report reviewedLost money on crypto? It could cut your tax bill.
A crypto loss can reduce tax on future gains, but only if you claim it within four years of the end of the tax year. Many people never do. Every pack lists your losses and their deadlines.
Built on real, messy portfolios
I built this engine to sort out my own crypto, a genuinely tangled portfolio: several chains and exchanges, Hyperliquid futures, staking and Bittensor subnets, and thousands of trades that tax software couldn't follow. Since then it has untangled portfolios for friends and others in the crypto community, and the same engine is now available as a service. It gets smarter with every case: new chains, protocols and HMRC updates are added as they arrive.
