The crypto data desk behind your practice.
From 2026, crypto platforms report their users' transactions to HMRC under the Cryptoasset Reporting Framework, and to EU tax authorities under DAC8. More clients will need their crypto history put in order, and most of it is not on an exchange statement. Lucidblock works behind your practice: we read the wallets, classify the activity and hand you a record you can rely on.
Where this fits in your work.
Self Assessment and personal tax
A complete, classified record for the tax year, in pounds or euros, that imports into your crypto tax software. Unknown transactions are investigated and either resolved or listed for the client to confirm.
Catching up earlier years
Rebuild a client's history across several years ahead of a disclosure or in response to a nudge letter.
Company accounts
Period-end balances and valuations for clients holding crypto on the balance sheet, with proof of control and the price source behind each figure.
Client due diligence
A source-of-funds report where your anti-money-laundering checks need to understand crypto-derived wealth.
The reports most relevant to you.
Crypto client pack
A clean, classified record of a client's crypto activity for a period, ready for their accountant.
Holdings statement
What a person or company held, where, at a date - with evidence of control and a valuation.
Source-of-funds report
The on-chain trail from first purchase to today, for a solicitor, bank or accountant.
An extension of your practice, not a competitor for your client.
Most practices already have the tax software. Koinly, Recap and similar tools handle exchange statements well. What they cannot do is read what happened once a client's assets left the exchange - and that is where the unknown transactions, the wrong disposals and the hours go. We do that part, and hand the result back into your software.
We are not accountants
We prepare the record. The computation, the treatment and the advice stay with you. We never contact your client directly unless you ask us to.
Delivered into your workflow
The classified ledger arrives as an import file for Koinly, Recap or CryptoTaxCalculator, plus a PDF you can put on the client file. Your branding on the pack if you prefer.
Fixed fee per client
Quoted up front from the number of wallets and transactions. Pass it through or mark it up - your choice.
Only when you need us
No subscription and no minimum. Send the messy cases: DeFi, several wallets, several years to catch up, or a client who has had a letter from HMRC.
Source of funds when your AML checks need it
The same wallets, written up as evidence of where crypto-derived wealth came from, for your client due diligence.
Turnaround that fits January
Five working days as standard, quicker by arrangement in the run-up to the Self Assessment deadline.
The few terms you will meet.
Reports are written for readers who do not work with blockchains every day. These are the only terms you need.
- Wallet
- An account on a blockchain that the client controls directly, outside any exchange. Most clients have several.
- On-chain
- Recorded on a public blockchain. Anyone can check it, and it cannot be edited.
- Own-wallet transfer
- The client moving assets between their own wallets. Not a disposal, but tax software often treats it as one.
- DeFi
- Lending, trading and earning yield through blockchain applications rather than a company. The source of most 'unknown' transactions.
- Staking reward
- Assets received for helping to run a network. Usually relevant as an income-type receipt.
We work for your practice, as a specialist behind your team. We do not give tax advice and we do not approach your clients.
