What information should I prepare?

Start with what you have: exchange transaction exports, public wallet addresses, any crypto tax software reports and notes about transfers between your own accounts. We will tell you what else is needed once we understand your activity.

Can you review an existing crypto tax report?

Yes. If you already have a report from crypto tax software or another adviser, we can look at it with you and raise any questions about the underlying records.

Can you help with DeFi, staking and NFTs?

Yes. These activities can be treated differently from simple buying and selling, so we review what you have actually been doing before explaining how it may need to be reported.

Do you work with companies as well as individuals?

Yes. Company tax rules differ from personal tax, so for companies we start with a conversation about the activity and agree the scope of work before anything else.

Can I enquire about previous tax years?

Yes. Tell us which years you are concerned about in your enquiry and we will discuss what is involved.

Your first consultation is free. Packages start at £399 + VAT per tax year for up to 100 transactions, and £799 + VAT per tax year for up to 1,000. For anything larger we quote once we understand the work; fees depend on things like the number of tax years, the volume of transactions, how many platforms you have used, the complexity of the activity and the state of your records.

Can the work be handled remotely?

Yes. Enquiries, records and conversations can all be handled by email and phone. You can reach us on 020 7118 9799.

Will you need access to my crypto?

No. We work from transaction records, exports and public wallet addresses. Never send anyone your private keys, seed phrases or exchange passwords, including us.
