The best crypto tax software for UK investors in 2026 is Koinly for most people, Recap if you want a UK-built tool tuned to HMRC rules, and CoinTracking for heavy traders. Here's how they compare on price, HMRC reports and pooling.
Important Risk Warning
This is not financial advice. Cryptocurrency investments are highly volatile. The value of your investment can go down as well as up, and you could lose all the money you invest. Don't invest unless you're prepared to lose all the money you put in.
For most UK crypto investors in 2026, Koinly is the best tax software — it imports from hundreds of exchanges, applies HMRC's pooling rules correctly, and spits out a Self Assessment-ready report. If you want a tool built in Britain specifically around HMRC rules, Recap is the standout, and for high-volume traders with complex DeFi activity, CoinTracking earns its keep. The right pick depends on your transaction count and how messy your history is.
Why bother with software at all? Because HMRC's share-pooling maths is genuinely fiddly, and doing it by hand across several exchanges and a year of trades is how mistakes happen. This is one area where £40 of software beats a weekend of spreadsheets.
Because the UK doesn't let you just tally buys and sells. HMRC uses Section 104 pooling, plus same-day and 30-day matching rules, to work out your cost basis on every disposal. Stack that across multiple exchanges, swaps, staking rewards and the odd NFT, and the calculation gets unwieldy fast.
Good software pulls in your transactions via API or CSV, reconciles transfers between your own wallets so they aren't mistaken for sales, applies the pooling rules, and produces the capital gains and income figures you drop straight onto your return. Our guide to filing crypto on Self Assessment shows where those numbers go.
| Tool | Best for | Free tier | Paid from | UK strengths |
|---|---|---|---|---|
| Koinly | Most UK users | View up to ~10,000 txns, no report download | ~£39/yr (100 txns) to ~£141/yr (1,000 txns) | HMRC report, broad exchange support, easy UI |
| Recap | UK-focused investors | Limited free tier | ~£119/yr | Built in the UK around HMRC Section 104, GBP CGT summaries, privacy-first (client-side encryption) |
| CoinTracking | Heavy/complex traders | Up to 200 txns | Lifetime licence ~£133 (up to 3,000 txns) | Deep portfolio analytics, margin and liquidity-pool support |
Prices move with promotions and the pound, so confirm the current plan before you buy. All three generate the figures you need for a UK return; the difference is fit.
If your activity is mainstream — trades on a couple of big exchanges, some staking, fewer than 1,000 transactions a year — use Koinly. It's faster, the interface is friendlier, and it gets HMRC reporting right without you configuring anything. The free tier lets you see your numbers before you pay for the downloadable report, which is a fair deal.
Recap deserves a serious look if you value that it's the only major UK-based platform, purpose-built around HMRC's rules, with strong privacy (your data is encrypted client-side). For a British investor who wants a tool that speaks Section 104 natively rather than translating from US tax logic, that's reassuring.
CoinTracking is the power user's choice — if you're running margin trades, liquidity pools and thousands of transactions, its analytics and one-off lifetime licence make sense. For a casual holder it's overkill. My honest opinion: don't over-buy. Most people need Koinly's mid-tier, not a professional suite.
The output is only as good as the input. Connect every exchange and wallet you've used, including ones you've abandoned, or the software will see coins appearing from nowhere and flag phantom gains. Reconcile internal transfers so moving Bitcoin from Coinbase to your Ledger isn't logged as a sale. And review the warnings the tool raises — missing cost basis on an old coin is the usual culprit behind an inflated bill.
Start early, too. Scrambling in late January with a year of unimported DeFi transactions is a recipe for errors. Pull your data in well before the 31 January deadline.
Does Koinly produce an HMRC-compliant report? Yes. Koinly generates a UK-specific report with capital gains and income figures using HMRC's Section 104 pooling and 30-day rules, formatted for the Self Assessment capital gains summary.
Is Recap better than Koinly for UK users? Recap is UK-built and tuned to HMRC rules with strong privacy, which some British investors prefer. Koinly is more widely used, supports more integrations and is often cheaper at low transaction counts. Both are solid; it's a fit decision.
Is there free crypto tax software in the UK? Koinly and CoinTracking offer free tiers for viewing and small transaction counts, but downloading the full tax report usually requires a paid plan. The free tiers are useful for checking your numbers first.
Do I still need an accountant if I use tax software? For straightforward holdings, the software alone is usually enough. For large portfolios, complex DeFi, or business activity, a crypto-savvy accountant adds value — and many use these same tools.
Can the software handle staking and DeFi income? Yes, the main tools categorise staking, mining and airdrop rewards as income and handle DeFi transactions, though complex protocols sometimes need manual review. See our DeFi tax guide.
Crypto tax software isn't a luxury in the UK — pooling rules make it close to a necessity once you're past a handful of trades. Koinly suits most people, Recap appeals if you want a home-grown HMRC-first tool, and CoinTracking covers the heavy traders. Connect everything, reconcile your transfers, and start before the January rush. This is general information, not tax advice.
