The UK crypto tax tool for your practice. Free.
Work out your clients' crypto Capital Gains Tax to the penny, produce the actual SA108 pages, and defend every figure against HMRC's own worked examples. Free for accountants who use it for client work.
Built for client work, and honest about it.
Free for your client work
Full access, including the SA108 download, at no charge to your practice.
Penny-accurate, and you can prove it
Reproduces HMRC's own worked examples to the penny, cross-checked against the independent BittyTax calculator. Every figure shows its working.
UK-native, SA108-ready
Built around HMRC's same-day, 30-day and Section 104 rules; fills the actual SA108 cryptoassets boxes.
It refuses to guess
If a client's data is incomplete, it flags the figure as provisional rather than handing you a confidently-wrong number.
Read-only, no access to funds
Works from a CSV export or manual entry only. No exchange API keys.

What's the catch? None, really.
It's free for your practice because we'd like you to think of CryptoCGT when your crypto clients need their gains worked out. No lock-in, no affiliate strings, no selling your clients' data. If it saves you time and you trust the numbers, that's the whole deal.
Every calculation is documented and checkable. See exactly how it's verified against HMRC's examples on our methodology page.
Free crypto tax tooling for your crypto clients.
Request access, we verify your practice, and you're working from the same penny-accurate figures your clients can trust.
The short version.
Is it really free for accountants?
Yes, for client work, granted on request.
What about my clients' data and security?
Read-only, CSV or manual entry only, no API keys. Data is handled privately.
Do you file on our behalf?
No. It produces the figures and the SA108 pages; you review and file.
