Capital Gains Tax on crypto assets.

Bitcoin, Ethereum, Solana and every other digital asset are treated by HMRC as property, not currency – disposals can trigger Capital Gains Tax. We help you stay compliant while planning tax-efficiently.

Does crypto trigger Capital Gains Tax?

Yes. HMRC does not treat crypto as currency – it is a digital asset, and every disposal can realise a gain or loss.

Selling for fiat

Converting crypto to GBP, USD or EUR.

Swapping crypto for crypto

E.g. exchanging Bitcoin for Ethereum – still a disposal.

Spending or gifting it

Paying for goods and services, or gifting to anyone but a spouse.

Mining, staking rewards and airdrops may be treated as income at the point of receipt, with subsequent disposals falling under CGT – we help you tell the two apart.

How gains are calculated

Unlike shares, crypto is pooled using Section 104 holdings – all identical assets are pooled together, and the cost basis is the average purchase price across all acquisitions. We handle these calculations even across hundreds of transactions and multiple exchanges.

HMRC has access to transaction records from major exchanges including Coinbase, Binance and Kraken. If you have traded without reporting, assume HMRC already knows – proactive disclosure is far cheaper than waiting to be found.
