# Crypto tax software for HMRC — how to choose (UK 2025/26)

Choose software that applies HMRC share pooling, same-day and 30-day rules automatically and outputs SA108-ready totals. Popular UK-compatible options include Koinly, Recap and Coinpanda. HMRC does not endorse any tool — you remain responsible for your return. Review every figure before filing.

## Key facts
- US-default FIFO is wrong for HMRC — check UK settings.
- Free tiers may show calculations but charge to export.
- DeFi-heavy portfolios need strong on-chain support.
- Software does not replace understanding when to report.
- Keep CSV exports as evidence for five years.

## What good UK software must do

Import exchange and wallet history, classify transactions (buy, sell, swap, income), apply Section 104 pooling with same-day and 30-day matching, convert to sterling at transaction dates, separate income from capital gains, and export totals for SA108 boxes.
## Koinly, Recap and Coinpanda

Koinly and Coinpanda are widely used in the UK with HMRC-oriented reports. Recap is UK-native. All require accurate API or CSV imports. Compare pricing per tax year if you only need one back year amended.
## Limitations and manual review

Software misclassifies DeFi, internal transfers and wrapped tokens. Review ‘unknown’ transactions. HMRC may ask for your working — software output is not proof on its own.
## Accountant vs DIY

DIY with software suits straightforward exchange trading. Complex DeFi, business trading or large undisclosed years may need an accountant. See our voluntary disclosure guide if catching up.

## FAQs
### Does HMRC accept Koinly reports directly?

You enter totals on Self Assessment — attach workings only if HMRC asks.
