Cryptocurrency Tax Reporting Services UK: Expert Tax Accountants
Still unsure how to report your crypto to HMRC without getting flagged or fined?
At Crypto Tax Accountants We work with UK crypto investors, traders, and Web3 professionals who want one thing: accurate, bulletproof tax reports that won’t trigger an investigation — or drain your profits unnecessarily.
Whether you’re yield farming on Lido, flipping JPEGs on Blur, or running validator nodes, we know what HMRC wants to see… and what they’ll red-flag. We clean up on-chain chaos and turn it into clean, compliant filings.
Our Services
We’re not general accountants guessing our way through Etherscan. We live and breathe crypto tax — with the audit support to prove it.
Wallet & Exchange Reconciliation
We pull transaction history directly from your wallets, CEX accounts, DeFi protocols, CSVs, and APIs. This includes:
- Layer 1 and Layer 2 support (Ethereum, Arbitrum, Optimism, Solana, BSC, etc.)
- Tracking smart contract interactions
- Recognizing wrapped tokens and liquidity pool deposits as taxable events
- Fixing broken imports from CoinTracking, Koinly, and Recap
Problem Solved: No more holes in your history. We map every transaction, convert timestamps to UK tax years, and match each movement with GBP spot prices for compliance.
Capital Gains Tax (CGT) Calculations
We apply the correct HMRC pooling method (section 104 rules), same-day rules, and 30-day bed & breakfasting — the technical approach HMRC expects.
We calculate gains on:
- Trades and swaps (e.g., ETH to USDT, NFTs to ETH)
- Token disposals and cashouts
- Wrapped token unwraps (stETH → ETH)
- LP token redemptions
- Cross-chain bridge movements with value shifts
Problem Solved: You’ll know exactly what your CGT liability is. No overpayment, no nasty letters, no confusion.
Income Classification and Tax Treatment
We categorize all forms of crypto income and apply the correct UK treatment, including:
- Mining rewards (income)
- Airdrops (depends on conditions)
- Referral bonuses (miscellaneous income)
- Staking and validator rewards (income unless paired with trade)
- Token vesting (spread over tax years)
Problem Solved: We stop HMRC from thinking you’re hiding income by explaining — in tax language — what every transaction is and why it’s correctly handled.
Self-Assessment Filing (SA100 & SA108)
We generate reports ready for submission or submit directly through your accountant or our partners. This includes:
- Capital gains summary
- Income statements with categorization
- Supporting documentation (PDF + CSV formats)
- Wallet audit trails
- Token-by-token breakdown
Problem Solved: No more guessing on tax forms. You get HMRC-compliant, fully reconciled reports that can stand up to review.
DeFi, DAO, and NFT Support
If you’ve interacted with dApps, DAOs, or run your own project, your tax treatment is layered. We handle:
- NFT income and royalties
- DAO token allocations
- Governance tokens
- DeFi LP token events
- Protocol rewards and rebase tokens
- Flash loans and leverage products
Problem Solved: We track it all. We don’t rely on integrations that miss half your activity. We build custom workflows if needed.
Audit-Ready Documentation
If HMRC ever questions your report — and they might — you’ll have:
- Full reconciliation documents
- Matching tx hashes and fiat values
- Wallet screenshots
- Supporting legal position (where needed)
Problem Solved: You stay protected with a clean, verifiable paper trail. We’ve supported clients through reviews and came out clean every time.

FAQs
We track every crypto-to-crypto swap (like ETH to USDC) as a disposal event, calculate the exact GBP value at the time of trade, and apply HMRC’s capital gains rules. Our reports ensure every swap is fully reconciled and reported properly.
Yes. We automatically pull and deduct eligible trading fees from your capital gains calculations, reducing your overall tax exposure in line with HMRC allowances.
We trace and apply gas fees where they relate to acquisitions or disposals, ensuring they’re deducted correctly to lower your taxable gain. Routine transfer gas fees are handled separately so that the report stays compliant.
We categorize your airdrops based on how you received them. If they were unsolicited, we report gains only upon disposal. If they were earned (like through tasks or bounties), we report them as miscellaneous income in your Self-Assessment.
Yes. We match internal wallet transfers using wallet addresses and transaction IDs, so you aren’t incorrectly taxed for moving your own assets between accounts.
We calculate your staking rewards on the date they were received, record them as miscellaneous income, and incorporate them correctly into your Self-Assessment filing, ensuring no double-counting when you later dispose of those assets.
Yes. We categorize NFT disposals separately, apply the correct CGT treatment, and document acquisition and sale values clearly. Whether you’re flipping art or managing NFT royalties, we handle it with the right tax structure.
If your exchange data is incomplete, we reconstruct your trade history using wallet analysis, on-chain explorers, and reliable GBP pricing sources, so your report stays legally defensible.
Yes. If eligible, we prepare the necessary negligible value claim forms and supporting documentation to submit to HMRC, which can potentially offset other gains and reduce your tax liability.
We supply you with transaction-level documentation, full reconciliation reports, and detailed event descriptions. If HMRC contacts you, you’ll already have a clear, credible defense — prepared by us.
