How we fit in
Specialist crypto tax support that fits into your existing client process while your firm keeps the wider relationship and filing work.
You keep the client relationship. We handle the crypto tax work.
Your firm stays in control of the wider job, while BlockBooks handles the specialist crypto work and returns clear reports your team can rely on.
Introduce the client
Send the client over directly or make the introduction once you know crypto is in scope.
We gather and reconcile
Wallet addresses, exchange exports, and missing records are pulled together without drawing your team into detailed reconciliation work.
You receive a usable pack
We return the capital gains and income support, plus the working notes that make the position intelligible.
HMRC-ready working papers
SA108 capital gains support, income schedules, and the notes needed to explain treatment.
Full audit trail
Every transaction mapped and traceable so your team is not left defending an unexplained output.
Direct collaboration
Questions, oddities, and scope changes are discussed in plain language before they become year-end problems.
Broad activity coverage
Exchange trading, DeFi, staking, NFTs, bridging, liquidity pools, and multi-wallet activity across tax years.
Built on accounting and transaction experience.
BlockBooks is led by Tim Whitehouse, who started his career in audit at EY before working in their acquisition due diligence team. He then went on to build one of the first wave of cloud accounting firms. That background matters because the job is not just classification accuracy. It is returning work in a format a practice can rely on.
Connect with Tim on LinkedInThe client relationship stays with you
Your firm stays front and centre. We support the crypto work inside that framework.
Pricing agreed early
Pricing reflects wallets, exchanges, years, and activity so expectations are clear from the start.
Clear where judgement is needed
Where treatment depends on protocol mechanics or missing history, that is surfaced and explained rather than buried.
Next step
If crypto starts complicating client work, bring in a specialist.
We can talk through fit, process, and how BlockBooks would work alongside your firm.
