The best crypto tax software for UK in 2026 (Koinly, Coinpanda, CoinLedger)
What's new in 2026: CARF imports, AI DeFi categorisation and refreshed HMRC export formats. Side-by-side review of Koinly, Coinpanda and CoinLedger for UK Self Assessment.

2026 is the first tax year where the Crypto-Asset Reporting Framework is in live operation, AI-driven DeFi categorisation has matured, and crypto tax exports are no longer a creative reconstruction exercise. The best tools have absorbed those changes; the worst are still catching up. Here is the 2026 UK shortlist.
What changed in 2026
- CARF live reporting.Most major exchanges now share standardised customer data with HMRC, and the same export feeds power the tax tools. Importing from Coinbase or Kraken has gone from "reconcile this messy CSV" to "everything matches first time" in most cases.
- AI DeFi categorisation. Tools now classify on-chain transactions (mint, burn, swap, claim, restake, bridge) automatically. Two years ago, a single Pendle position could generate twenty manual decisions. In 2026, most are correct on first sync.
- Refreshed HMRC export. The Capital Gains Summary PDF now maps line-for-line to the 2025/26 SA108 boxes 14-22, with a separate income summary for SA100 box 17.
- Higher CGT rates baked in. 18% basic and 24% higher are the live numbers in every calculator. Older versions still showing 10%/20% are out of date.
The 2026 shortlist
Koinly — best UK overall
Koinly remains the default UK choice. Pricing in 2026 starts at approximately £39 for 100 transactions and runs to £159 for 10,000+. Strengths in 2026:
- HMRC matching done right. Same-day, 30-day and Section 104 applied in correct order out of the box.
- SA108-mapped report. Boxes 14-22 are pre-totalled. You paste numbers without re-typing.
- Free preview.See the full report before paying. Useful for confirming you are under £3,000 and don't need to file the gains element.
- £3,000 AEA tracker. Live dashboard widget showing how much exempt allowance you have used.
- 800+ exchanges, 170+ blockchains. Best coverage of any UK-friendly tool.
- Accountant invite. Read-only access for your accountant at no extra cost.

Coinpanda — best free tier
Coinpanda is the only mainstream tool offering a downloadable HMRC report on the free plan, capped at 25 transactions. For a buy-and-hold investor with a handful of disposals, that is the entire job done for £0. Beyond 25 transactions, paid plans run from approximately £49 to £189.
UK share-pooling is correctly implemented. DeFi categorisation is good but slightly less polished than Koinly on more obscure protocols. The 2026 update added CARF-aligned exchange imports and a cleaner SA108 export.
CoinLedger — best dual-jurisdiction
CoinLedger is the leader in the US market and has built solid UK support over the last two tax cycles. The compelling case is dual filing: one subscription generates a Form 8949 for the US and an SA108- compatible report for the UK from the same data.
Pricing starts at about £39. The 2026 release added refined Section 104 logic and a shared dashboard for filers with both UK and US obligations. Pure UK filers usually still prefer Koinly.

When to choose each
Choose Koinly if you are a UK filer with more than 25 transactions, want the cleanest SA108 mapping, or have any DeFi or staking activity. This is the default for nine out of ten readers.
Choose Coinpandaif you have 25 or fewer transactions and want to file for free, or if you are price-sensitive at higher tiers and don't need the broadest exchange list.
Choose CoinLedger if you also file in the US and want one subscription, one dashboard and one source of truth for both jurisdictions.

Frequently asked questions
What's new in crypto tax software in 2026?
Three things: CARF imports (exchanges share standardised data with HMRC, and tools now ingest the same feeds), AI categorisation of DeFi protocols (which fixes most missing-cost-basis warnings automatically), and refreshed HMRC export formats matching the 2025/26 SA108 boxes.
Is Koinly still the best for UK in 2026?
Yes. Koinly remains the most accurate on share-pooling, has the cleanest SA108 mapping, and tracks the £3,000 annual exempt amount on the dashboard. Coinpanda is a strong free option and CoinLedger wins for dual UK/US filers.
What does CARF mean for me as a user?
Practically, exchanges now generate standardised tax exports that match what they already send HMRC. Connecting the export to your tax tool means HMRC, the exchange and your tool all see the same numbers — much harder to mis-file by accident.
Do these tools handle staking and DeFi?
Yes. All three handle Ethereum staking, liquid staking (Lido, Rocket Pool), lending (Aave, Compound) and major DEX swaps. Koinly's coverage of obscure DeFi protocols is broadest. CryptoTaxCalculator goes deeper still if you have heavy Layer-2 DeFi.
