Kraken UK Tax Report 2026/27: Does Kraken Report to HMRC? Complete Guide
Does Kraken report to HMRC? Yes — and here is exactly how to export your Kraken ledger, value staking and Earn rewards, and apply UK Section 104 pooling for the 2026/27 tax year.
Kraken offers some of the most detailed transaction exports of any exchange, which is good news for UK taxpayers but can be overwhelming if you do not know which files you need. This guide shows exactly what to download from Kraken to complete your HMRC Self Assessment for the 2026/27 tax year (and the still-fileable 2025/26 year, with a deadline of 31 January 2027).
Does Kraken report to HMRC?
Yes. Kraken (Payward Ltd in the UK) is FCA-registered and falls inside the Crypto-Asset Reporting Framework (CARF) which became active for UK reporting in January 2026. That means Kraken now shares transaction-level data with HMRC: your verified identity, gross disposals, total volume and reportable crypto-asset transfers. Filing accurately is no longer optional — the data already sits on HMRC's side.
Ledgers vs trades — why you need both
Kraken splits exports into two logs. The "trades" export lists matched buy and sell executions. The "ledgers" export lists every account movement — deposits, withdrawals, fees, staking rewards, and the individual legs of each trade. For HMRC, you need ledgers because they capture staking and rewards income, which the trades file misses entirely. If you only use the trades file you will under-report income.
How to export ledgers
Log in to Kraken on a desktop browser. Go to History then Export. Set "Type" to Ledgers. Set the date range to 6 April 2025 to 5 April 2026. Leave all asset types selected. Click Submit. Kraken emails you a download link, typically within a few minutes. The CSV includes every credit and debit in your account, along with timestamps, transaction types, and fees.
The key transaction types
In the Kraken ledger, "deposit" and "withdrawal" are not taxable events on their own — they are movements in and out of the platform. "Trade" entries are the two legs of an executed order; match them by refid to reconstruct the full trade. "Staking" entries are rewards received from Kraken's staking service and are income at GBP value on receipt. "Transfer" entries are often internal movements — Spot, Earn, Futures wallets — and are not disposals for tax purposes.
Staking and Earn — income, not CGT
If you used Kraken Staking or Earn during 2025/26 and received rewards, those are taxable as income at the GBP market value on the day the reward credited your account. They are not capital gains until you later dispose of the tokens. The cost basis of the staked tokens is the GBP value at the moment you received them, which becomes your acquisition price for future Section 104 pooling.
GBP conversions for non-GBP trades
Kraken supports many fiat pairs. If you traded in USD, EUR, or another non-GBP currency, you must convert every transaction to GBP at the historical spot rate on the date of the trade. HMRC accepts any reasonable conversion methodology as long as you apply it consistently. CryptoLens handles this conversion automatically using end-of-day reference rates.
Applying UK pooling rules
Once you have the Kraken ledger CSV, you apply same-day matching first, then the 30-day bed-and-breakfasting rule, and finally Section 104 pooling for anything left over. This is where manual spreadsheets fall apart — even a few hundred transactions become unmanageable. CryptoLens applies all three rules automatically when you upload your Kraken export, producing a full SA108-ready tax summary with a complete audit trail. If you also use Coinbase or Binance, the imports combine into one return so the pools span every account.
Frequently asked questions
Does Kraken report to HMRC?
Yes. Kraken (Payward Ltd) is FCA-registered in the UK and reports under CARF from January 2026. It shares your account identity, gross disposals, and transaction-level data with HMRC.
Why do I need both Kraken trades and ledgers exports?
Trades only show matched buy/sell executions. Ledgers also include staking rewards, Earn rewards, fees, and every individual account credit/debit — which is what HMRC needs to capture income correctly.
Are Kraken staking and Earn rewards taxable in the UK?
Yes. Kraken staking and Earn rewards are taxable as miscellaneous income at the GBP value at the moment they credit your account. That GBP figure also becomes the cost basis for future Capital Gains Tax when you dispose of the tokens.
I trade in USD on Kraken — what do I do for HMRC?
Every non-GBP trade must be converted to GBP at the historical spot rate on the trade date. HMRC accepts any consistent methodology; end-of-day reference rates are the norm. CryptoLens does this conversion automatically.
Is moving crypto between Kraken Spot, Earn and Futures a disposal?
No. Internal transfers between your own Kraken wallets are not disposals. They are movements within your own custody. Only trades and external sends to other parties count.
