In-Depth Reviews
Koinly
Koinly is the most popular crypto tax tool globally, and for good reason. It auto-imports data from over 800 exchanges, wallets, and blockchains — covering virtually every platform a UK investor might use. Once your transactions are imported, Koinly automatically categorises them and generates HMRC-compatible Capital Gains reports, including the SA108 supplementary pages you need for your Self Assessment tax return.
The free tier is generous, allowing up to 10,000 transactions for portfolio tracking. However, generating tax reports requires a paid plan. Pricing starts at £49 per year for up to 100 transactions, £99 for up to 1,000 transactions, and £179 for 3,000 or more. For active traders, these costs can add up, but the time saved on manual calculations often justifies the expense.
DeFi, staking, and NFT transactions are all supported. Koinly can read on-chain data directly, making it straightforward to account for liquidity pool activity, yield farming rewards, and NFT sales. The platform also handles token swaps, airdrops, and forks with minimal manual intervention.
CoinLedger
CoinLedger (formerly CryptoTrader.Tax) stands out for its clean, beginner-friendly interface. If you are new to crypto tax filing, CoinLedger is one of the easiest platforms to get started with. The onboarding process walks you through connecting your exchanges step by step, and the dashboard presents your tax liability in a straightforward, jargon-free layout.
The pricing model is refreshingly transparent: you can import all your transactions and preview your complete tax report for free. You only pay when you want to download the final report. Plans start at $49.95 per year, making it competitive with other tools on the market. CoinLedger generates HMRC-compatible reports that you can use to complete your UK Self Assessment.
With over 400 exchange integrations, CoinLedger covers all major platforms including Coinbase, Binance, Kraken, and more. DeFi support is available through blockchain imports — you can connect your wallet address and CoinLedger will pull in on-chain transactions. However, the DeFi categorisation is not as comprehensive as some competitors, and you may need to manually review certain complex transactions.
Recap
Recap is the only tool on this list built in the UK specifically for HMRC compliance. That UK-first approach means every report it generates is aligned with HMRC guidance on how crypto assets should be taxed. If you want confidence that your tax calculations follow HMRC rules to the letter — including their specific guidance on pooling, same-day rules, and the 30-day matching rule — Recap is hard to beat.
The free tier allows up to 1,000 transactions, which is sufficient for casual investors. Paid plans start from £15 per month, making Recap one of the more affordable options for ongoing use. The platform generates Capital Gains reports that map directly to the SA108 form, and it also provides a detailed breakdown of each disposal so you can verify the calculations yourself.
The main limitation is the number of exchange integrations. With around 50 supported platforms, Recap covers all the major UK-accessible exchanges (Coinbase, Binance, Kraken, Gemini) but may fall short if you use niche or region-specific platforms. DeFi support is also more limited than competitors, so if you have a complex portfolio with extensive on-chain activity, you may need to supplement Recap with manual entries.
Crypto Tax Calculator
Crypto Tax Calculator is the go-to choice for users with complex portfolios involving heavy DeFi activity. With over 3,000 integrations spanning exchanges, wallets, and DeFi protocols, it has the largest integration library of any tool on this list. If you are deeply involved in yield farming, liquidity provision, cross-chain bridging, or NFT trading, Crypto Tax Calculator is likely to handle your transactions more accurately than the competition.
The platform generates HMRC-compatible reports and supports multiple tax jurisdictions, so it is also a good choice if you have tax obligations in more than one country. The free tier covers up to 200 transactions with full tax reports included. Paid plans range from $49 per year for 100 transactions up to $299 per year for unlimited transactions — so costs can climb if you are an active trader.
The trade-off for all this power is complexity. The interface is more technical than CoinLedger or Koinly, and new users may find the dashboard overwhelming at first. However, once you understand the layout, the depth of information and control available is impressive. The platform also provides an audit trail for every transaction, which is valuable if HMRC ever queries your return.
Awaken Tax
Awaken Tax is a newer entrant to the crypto tax software market, positioning itself as a simple and affordable alternative to the more established players. If you have a straightforward portfolio — primarily buying and selling on major exchanges — and you want to minimise costs, Awaken Tax is worth considering. The interface is clean and uncluttered, focusing on getting you from import to tax report with minimal friction.
With a free basic tier and paid plans starting at just $29 per year, Awaken Tax is the most affordable paid option on this list. It supports over 150 exchange integrations, covering all the major platforms like Coinbase, Binance, and Kraken. HMRC-compatible output is available, so you can use the generated reports for your UK Self Assessment filing.
The main drawbacks are the areas you would expect from a newer platform: fewer integrations, less mature DeFi support, and a smaller community of users sharing tips and troubleshooting advice. If your portfolio is simple and you want to keep costs down, Awaken Tax delivers solid value. But if you have complex DeFi activity or use niche exchanges, you may find its limitations frustrating.
How Crypto Tax Works in the UK
In the UK, HMRC treats cryptocurrency as property rather than currency. This means Capital Gains Tax (CGT) applies whenever you dispose of a crypto asset — whether you sell it for GBP, swap it for another token, or spend it on goods and services. Each of these events is a taxable disposal, and you need to calculate the gain or loss on each one.
For the 2025/26 tax year, the annual CGT allowance is £3,000. You only pay tax on gains above this threshold. Basic rate taxpayers pay 18% on crypto gains, while higher and additional rate taxpayers pay 24%. You report your crypto gains through Self Assessment using the SA108 Capital Gains supplementary pages.
Income tax may also apply in certain situations. If you receive crypto through mining, staking rewards, airdrops, or as payment for services, HMRC may treat this as income rather than a capital gain. You are required to keep records of all your crypto transactions, including dates, amounts, and the GBP value at the time of each transaction.
Using dedicated crypto tax software simplifies this process significantly. These tools automatically import your transaction history, calculate your gains and losses using HMRC-approved methods, and generate the reports you need for your tax return.

What to Look for in Crypto Tax Software
HMRC report generation is the most important feature for UK users. The software should produce Capital Gains reports compatible with the SA108 form, applying HMRC's specific calculation rules including the same-day rule, the 30-day bed-and-breakfasting rule, and Section 104 pooling.
Exchange and wallet integrations determine how easily you can import your data. The more integrations a tool supports, the less manual work you need to do. Check that the tool supports every exchange and wallet you use before committing to a paid plan.
DeFi, staking, and NFT support matters if you go beyond simple buy-and-sell trading. These transactions are notoriously difficult to categorise for tax purposes, and good software will handle them automatically.
Cost relative to your transaction volume varies significantly between tools. Compare the free tier limits and paid plan pricing against your actual number of transactions to find the best value.
Ease of use and customer support can make a big difference, especially if you are filing crypto taxes for the first time. Look for tools with clear documentation, responsive support teams, and an intuitive interface.
