CoinLedger review 2026: usable for UK CGT or US-only?

CoinLedger is a US-built crypto tax tool that scores 8.6/10 in our 2026 review. For UK filers it's a capable second-tier choice: it supports HMRC-style share-pooling and produces accurate gain/loss numbers, but it does not generate a Self Assessment-formatted Capital Gains Summary. Expect to do a bit of manual mapping onto SA108 boxes — workable, but more friction than the UK-native alternatives.

CoinLedger in two sentences

What is CoinLedger?

CoinLedger (formerly CryptoTrader.Tax) launched in 2018 in the US and has grown into one of the more popular crypto tax tools globally. Its main claim to fame is a deep TurboTax integration and a clean, fast UI. The platform supports 500+ exchanges, 100+ wallets and the major EVM-chain DeFi protocols, so import coverage is broad — even if the reporting is US-flavoured.

For UK users, CoinLedger sits in an awkward middle ground. The tax engine can be configured for HMRC pooling, but the company has not built a UK-native report. You get an accurate generic export and you do the SA108 mapping yourself.

UK-relevant features

• HMRC pooling option. The cost-basis method can be set to share-pooling rather than the US default of FIFO/HIFO, giving correct UK gain/loss totals.
• Multi-currency support. Transactions can be valued in GBP at the spot rate on the trade date, so your final figures are in pounds without an FX conversion step.
• Generic gain/loss export. A clean CSV listing every disposal — date, asset, proceeds, cost basis, gain/loss — that an accountant can drop into an SA108 working paper.
• Income report. Staking, mining and airdrop rewards in GBP, ready for the SA100 other-income section.
• 500+ integrations. Coinbase, Binance, Kraken, Crypto.com, Bitstamp, Gemini, plus the major wallets (Ledger, Trezor, MetaMask) and DeFi protocols.
• TurboTax integration. Useful for dual UK/US filers; irrelevant if you only file in the UK.

Pricing and free tier

CoinLedger's pricing converts from US dollars, so the pound figures shift slightly with the exchange rate. The pattern is the standard pay-on-export model: import everything for free, see your numbers, pay only when you need the downloadable report.

Like the others, CoinLedger charges per tax year. If you need to amend several back years, that's a separate charge each.

Our test

Same test portfolio: ~320 transactions across Coinbase, Binance, Kraken and Crypto.com, plus a Ledger and MetaMask wallet with a small DeFi position. CoinLedger imported the data quickly and the UI is genuinely nice — the "classify" flow for unmatched transfers is the cleanest of the three tools we tested.

Switching to share-pooling cost basis took two clicks. The gain/loss totals matched Koinly's within rounding (£14 difference on a five-figure gain), which suggests the underlying logic is sound. The 30-day rule was applied on the obvious cases but missed one we'd flagged as a re-acquisition seven days after sale on a different exchange — Koinly caught it; CoinLedger did not.

The export, however, is a generic CSV plus a US Schedule D / Form 8949 PDF. There's no SA108 layout, no boxes 14–22 mapping, and no UK-specific cover sheet. We pasted the totals into a spreadsheet and onto SA108 manually. It took about 20 minutes — fine if you do it once, irritating if you file every year.

Pros and cons

Our verdict

CoinLedger is a solid product, but for a UK Self Assessment it's a second-best choice. The lack of a native HMRC report and slightly weaker 30-day matching mean you spend the price difference (versus Koinly) in manual time anyway. We'd only recommend it for UK filers who also have US tax obligations and want a single tool, or for very small portfolios where the price genuinely matters.

For most UK filers, our top pick remains Koinly. If your portfolio is small and budget is the priority, see our Coinpanda review. The full picture on share-pooling, the 30-day rule and SA108 lives in the UK crypto tax guide.
