CoinTracker is one of the oldest crypto tax tools around — founded in 2017 and used by millions globally. The problem for UK investors is that it was built for US tax forms, and UK HMRC compliance is a secondary market. If you have been using CoinTracker and wondering whether there is a better fit, here is what to consider.
What CoinTracker does well and where it falls short for UK users
CoinTracker has a genuinely good portfolio tracking interface and strong Coinbase integration — which makes sense given it was partly backed by Coinbase. The UK HMRC matching rules are implemented, and the tool works for straightforward portfolios. The limitations that UK investors most commonly cite are: the free plan caps transactions at 25 (not useful for anyone with real history), the pricing is on the higher end relative to UK alternatives, and the SA108 output has historically required more interpretation than tools designed with HMRC reporting as the primary output format.
CoinTracker's 25-transaction free limit means you cannot evaluate whether it handles your specific history correctly before committing to payment. Check whether the tool handles your particular exchange exports before upgrading.
The best CoinTracker alternatives for UK investors
Polyconomic
Try freeThe most significant difference from CoinTracker is immediate: the free tier shows your complete taxable gain for all tax years without any transaction cap. There is no 25-transaction limit, no paywall to see your own number, and no guessing whether the tool will handle your history correctly. HMRC's three matching rules are the default and only calculation mode — not a country setting you need to select. SA108-compatible PDF reports are available on Standard at £49/year. If you turn out to owe nothing and do not need a report, you pay nothing at all.
Best for: UK investors who want to see the full picture before committing any payment.
Koinly
Broader exchange integration library than CoinTracker and more widely used by UK investors. The subscription model is similar to CoinTracker in structure, but Koinly's UK HMRC implementation is more mature. Better DeFi support than CoinTracker. If your primary reason for leaving CoinTracker is the 25-transaction free limit, Koinly's free tier gives you more access before committing, though you still need a paid plan for report download.
CryptoTaxCalculator
Significantly better than CoinTracker for DeFi-heavy portfolios. If you have been struggling with CoinTracker misclassifying DeFi transactions — protocol interactions, LP deposits, multi-step swaps — CTC's categorisation engine handles these more reliably. Australian-origin but with solid UK HMRC support. Subscription-based with pricing similar to CoinTracker.
Blockpit
Worth considering if you have European tax obligations alongside UK. CoinTracker's European jurisdiction support is limited; Blockpit handles German, Austrian, and other EU regimes more naturally. Subscription-based, typically at a slightly higher price point than CoinTracker. For UK-only portfolios, there is no specific advantage over other alternatives.

Frequently asked questions
Can I import my CoinTracker history into another tool?
Most tools allow you to export your transaction history as a CSV and re-import it. However, it is usually better to re-import from the original exchanges rather than from a CoinTracker export, as this ensures the full raw data is used and any categorisation errors from CoinTracker are not carried over.
Does CoinTracker correctly handle HMRC's 30-day bed-and-breakfasting rule?
CoinTracker implements the 30-day rule, but like all tools, the quality of implementation matters in edge cases. If you have sold and repurchased the same asset within 30 days of each other, verify that the tool has correctly matched the sale against the repurchase rather than the Section 104 pool.
I only have 20 transactions — should I bother with any paid tool?
If you have 20 transactions and they are all simple exchange trades, a free tool that shows you the full gain (like Polyconomic) is all you need. You only need to pay if you want the downloadable PDF report for filing purposes. With 20 transactions, the calculation is also simple enough to verify manually.
Which tool has the best Coinbase integration?
CoinTracker has a historically strong Coinbase integration, which makes sense given the relationship. Polyconomic also supports Coinbase via API and CSV. For most Coinbase users, any of the major tools will handle the import reliably.
Is CoinTracker's UK HMRC output accurate enough to use for filing?
CoinTracker implements the UK HMRC matching rules and the output is used by UK investors for filing. The quality of any tool's output depends heavily on the completeness of your imported data — garbage in, garbage out. Always verify that your complete transaction history is imported before relying on any report.
What is the main reason UK investors switch away from CoinTracker?
The most common reason cited is the 25-transaction free limit, which makes it impossible to evaluate the tool with real data before paying. The second most common reason is the US-first design, which means the UK output format and support documentation are less tailored to HMRC-specific workflows.
