TaxBit raised over $130 million in venture capital and built an impressive platform — primarily for US enterprises and institutional clients. For a UK individual investor trying to work out their HMRC position, it is almost certainly the wrong tool, and the alternatives are significantly better suited and more affordable.
Why TaxBit is rarely the right choice for UK individuals
TaxBit's primary output format is US tax forms — Form 8949 and Schedule D. UK HMRC reporting is a secondary product. The platform is designed around enterprise workflows: corporate treasury management, exchange reporting obligations, institutional-scale transaction volumes. Individual UK retail investors are not the target customer. Pricing reflects this — TaxBit's retail plans, where they exist, are expensive relative to UK-specific alternatives, and enterprise pricing is aimed at businesses rather than individuals.
TaxBit has changed its product offering and pricing multiple times. Some retail plans have been discontinued. If you are considering TaxBit, verify the current availability of individual-tier plans on their website before proceeding.
Better alternatives for UK individual investors
Polyconomic
Try freeBuilt from the ground up for UK HMRC reporting — not a US tool with a UK mode bolted on. The pricing model is designed for individuals: free to see your full taxable gain, Standard at £49/year for the SA108-compatible PDF if you need it. In years where you owe nothing and do not need a report, the cost is £0. HMRC's three matching rules are the only calculation mode. If you are coming from TaxBit and found the UK output underwhelming or the pricing unjustifiable, Polyconomic is likely what you were looking for.
Best for: UK individual investors who want HMRC-correct figures without enterprise pricing.
Koinly
A far more accessible alternative to TaxBit for individual investors. Subscription-based at approximately £49 per year, with strong exchange integration and UK HMRC support. Not UK-specific, but widely used by UK investors and generally well-regarded for straightforward to moderately complex portfolios. Much more transparent pricing than TaxBit and genuinely suited to retail rather than institutional use.
CryptoTaxCalculator
Strong DeFi support and UK HMRC mode. Good for investors with complex on-chain history who need better transaction categorisation than TaxBit provides for non-enterprise clients. Subscription-based at a retail price point. Particularly useful if your portfolio includes multiple chains and DeFi protocols.
A specialist UK crypto tax accountant
If your reasons for looking at TaxBit were genuine enterprise-level requirements — corporate treasury, large-scale trading, multi-jurisdiction obligations — then a qualified accountant using professional-grade tools is likely more appropriate than any consumer software. The cost of professional advice is often lower than expected, and for complex situations the accuracy and defensibility of a professionally prepared return is worth it.

Frequently asked questions
Does TaxBit have any UK retail plans at all?
TaxBit has changed its retail offering multiple times. It has had periods where individual plans were available and periods where it focused entirely on enterprise. Check their current website for the latest position. As of this writing, TaxBit is primarily positioned as an enterprise and business platform.
If I used TaxBit for a year, can I switch tools and carry over my data?
Yes, but the best approach is to re-import your transaction history from the original exchanges rather than exporting from TaxBit. This ensures you have clean, unmodified source data and avoids carrying over any categorisation decisions that may not be appropriate for UK HMRC reporting.
Is TaxBit actually wrong for UK users, or just overpriced?
Both are valid concerns. TaxBit was primarily designed around US tax forms, and the UK HMRC implementation may not apply the three matching rules with the same reliability as UK-specific tools. Additionally, it is overpriced for what UK retail investors need. These are two separate issues.
Are there any scenarios where TaxBit is genuinely the best option for a UK user?
For UK businesses operating as a crypto exchange or institutional trading desk with US cross-border obligations, TaxBit's enterprise features may be relevant. For UK individuals — even high-net-worth ones with large portfolios — it is very rarely the right tool.
What should I look for in a TaxBit alternative for UK use?
Prioritise correct HMRC matching rules (same-day, 30-day, Section 104) applied by default without manual configuration, SA108-compatible output with box numbers explicitly referenced, transparent individual pricing rather than enterprise tiers, and the ability to see your gain before paying for a report.
Can any tool handle both enterprise use cases and UK HMRC individual reporting?
Not in a single consumer product. For genuine enterprise-scale UK operations, a combination of professional accounting software and a specialist crypto tax accountant is more appropriate than any single consumer tool, regardless of how it is marketed.
