Built to make crypto tax feel defensible, not mysterious.
BlockBooks is a UK-focused crypto tax service for investors, founders, and the accounting practices that support them. The work is grounded in accountancy practice: structured enough to handle complexity, careful enough to stand up to scrutiny.
What the service is
Specialist crypto tax support for UK reporting.
Operating principle
Make things clear, keep a record of how everything was handled, and explain any judgement calls.
The aim is not to make crypto look simpler than it is. It is to turn a messy transaction history into something coherent and usable by the time it reaches a return.
Who it serves
Investors with real on-chain complexity and firms that want specialist crypto support without losing control of the client relationship.
What it avoids
Unnecessary access, cookie-cutter outputs, and reports that leave the next reviewer guessing what actually happened.
The design language needed backing values, not just decoration.
- Privacy and data minimisation over unnecessary access
- Clear explanations over black-box outputs
- UK-specific tax treatment that accountants can follow
Structured process where it helps
Pattern detection, transaction volume handling, and reconciliation support are handled consistently so the work stays efficient.
Human review where it matters
Complex DeFi, unusual wallet movements, and uncertain treatment are reviewed rather than forced into a one-size-fits-all output.
Outputs built to be used
The end product is a set of reports and supporting notes that an investor or accountant can actually use.
Tim Whitehouse built BlockBooks from an accounting viewpoint, not a crypto-enthusiast one.
Tim began as an audit graduate trainee at EY and progressed to Manager in Transaction Support, working through acquisition due diligence and complex balance-sheet detail. After leaving the Big Four, he founded one of the early online accounting practices built on Xero.
Crypto brought him back into specialist accounting work because it combines messy records, novel transactions, and a need for disciplined explanation. That is the thread running through BlockBooks.
Career thread
Audit, transaction support, practice building, then specialist crypto tax work.
