What is the Crypto Tax Record-Keeping & CARF Readiness Calculator?
The Crypto Tax Record-Keeping & CARF Readiness Calculator helps UK crypto investors assess whether their records are organised well enough for Self Assessment reporting and future Crypto Asset Reporting Framework (CARF) requirements.
Rather than calculating tax, the calculator focuses on record-keeping. It highlights gaps in your records, identifies areas that may need attention, and provides a readiness score based on the information you enter.
How the Calculator Works?
Enter details about your crypto activity, trading history, platforms used, and record-keeping habits.
The calculator then estimates:
- How complete your records appear to be
- Areas that may need attention
- Your overall CARF readiness score
- Actions that could improve your record-keeping
The results are designed to help you prepare for future reporting requirements and identify missing information before you need it.
Step 1: Tell the Calculator About Your Crypto Activity
Add the exchanges, wallets, platforms, and types of crypto activity you have used, such as trading, staking, DeFi, or swaps.
Step 2: Review Your Record Keeping
Work through the checklist covering transaction histories, wallet records, exports, cost basis information, and supporting documents.
Step 3: Review Your Readiness Score
See your overall readiness score, recommended actions, potential Self Assessment flags, and a checklist of areas that may need attention.

What is the Crypto Tax Record-Keeping & CARF Readiness Calculator?
The Crypto Tax Record-Keeping & CARF Readiness Calculator is a UK-focused checklist tool that helps crypto investors assess the quality of their records, identify missing information, and prepare for future reporting requirements such as CARF.
What is CARF?
CARF stands for the Crypto Asset Reporting Framework. It is an international reporting framework that requires participating crypto platforms to provide information to tax authorities.
Does CARF apply to individuals?
CARF reporting obligations apply primarily to platforms and service providers. However, individuals still need accurate records so their own figures can be reconciled against information reported to HMRC.
Does this calculator calculate crypto tax?
No. The calculator focuses on record keeping and readiness rather than tax calculations.
Does this connect to exchanges?
No. The calculator does not connect to exchanges, wallets, or APIs.
What records should crypto investors keep?
In general, investors should retain transaction histories, purchase records, disposal records, wallet information, transfers, staking records, and supporting documentation.
How long should I keep crypto records?
HMRC generally expects records relevant to Capital Gains Tax to be retained for several years. The calculator encourages maintaining long-term records and supporting documentation.
What does the readiness score mean?
The readiness score reflects the completeness of your records compared with the complexity of your crypto activity. It is an educational indicator, not an official assessment.
What is the Self Assessment flag?
The calculator may identify situations where a tax return could be worth investigating further. It is only a heuristic and should not be treated as a filing requirement.
Does the calculator tell me how much tax I owe?
No. It does not calculate gains, losses, income, or tax liabilities.
What happens when UK platforms start reporting under CARF?
Platforms may report information directly to HMRC. Keeping accurate records can help ensure your own figures match the information being reported.
Can I export my checklist?
Yes. The calculator includes a downloadable checklist and CSV export option.
Is this a substitute for an accountant?
No. The calculator is designed to help organise information and identify gaps, not replace professional advice.
