What the letter means
A clear plan for responding to HMRC
You do not need to work out the full answer before contacting us. Start with your letter and the records you have; we’ll help establish what needs checking and how to respond.
Check whether anything is missing
We compare your crypto activity with what you have already reported. The aim is to establish whether a correction is needed and calculate any tax due.
You can start before your records are complete
Tell us which exchanges and wallets you used. We explain which records to gather and identify gaps that need further work.
Agree the work and fee first
We confirm the tax years and work involved before starting. You receive a clear fee and an explanation of the next steps.

FAQ
What people ask when the letter arrives
What happens after I request a quote?
We call you to discuss the letter, its deadline and the years involved, then confirm the work and fee. The initial call is free and there is no obligation to proceed. You do not need to upload records or pay to enquire.
How long do I have to respond?
Use the response date in your own letter. Tell us that date when you enquire. If you cannot meet it, contact HMRC using the details in the letter to discuss what is needed; an extension is not automatic.
Will I get fined?
A letter alone does not establish whether a penalty is due. If there is unpaid tax, penalties depend on the facts, including why it arose, whether the disclosure is prompted and how you cooperate. We explain the position for your case; a quick reply does not guarantee a particular penalty outcome.
What if I don't have all my records?
You do not need complete records to enquire. Tell us which exchanges and wallets you used. We can help identify available exports and on-chain records, and explain any gaps or limitations.
Can you help with DeFi, staking and NFTs?
Yes. We review exchange trading, staking, DeFi and NFT activity, including transfers between your own wallets. We assess the transactions rather than assuming every wallet movement is taxable.
How much does this cost?
Crypto tax calculations start from £350 including VAT per tax year. We quote for the work your letter requires, including any correspondence or disclosure support, and confirm the total scope and fee before starting.
