Crypto and ISA Tax UK — Can an ISA Hold Crypto?
ISAs offer tax-free returns — but can you put crypto in one? This guide explains HMRC's current rules and the options available to UK investors. Educational only — not tax advice.
Estimate my crypto CGT outside an ISA →Direct crypto in an ISA
Currently, direct cryptocurrency cannot be held in a UK ISA. HMRC rules require ISA assets to be 'qualifying investments' and unregulated crypto assets do not currently meet this definition.
Crypto ETFs in a Stocks & Shares ISA
Since early 2024, regulated spot Bitcoin and Ethereum ETFs have been available on UK exchanges. These ETFs are qualifying investments for a Stocks & Shares ISA. If held within an ISA, gains and income are free of UK tax.
ISA allowance planning
The annual ISA allowance is £20,000 per person for 2025/26. If you hold crypto outside an ISA, consider whether it would be beneficial to realise gains and reinvest via a regulated crypto ETF within your ISA for future tax-free growth.
Frequently asked questions
