By It is one of the most common questions we hear: can you hold crypto in an ISA and shelter the gains from tax? The honest answer is: not directly, and the rules around indirect exposure have moved quickly over the past year. What was allowed in November 2025 changed in April 2026, and the position may move again.
Here is where things stand, and the checks to make before you act.
The short answer
- Direct crypto: no. Coins and tokens themselves have never been ISA-qualifying investments, and that has not changed. You cannot put Bitcoin, Ether or any other cryptocurrency directly into an ISA.
- Crypto ETNs: it is complicated. These listed products could be bought in stocks and shares ISAs for a brief window from October 2025, but from 6 April 2026 the rules changed, and new purchases in stocks and shares ISAs stopped.
What is a crypto ETN?
An exchange-traded note (ETN) is a debt security, listed on a stock exchange, that tracks the price of an underlying asset such as Bitcoin. You buy it through a stockbroker like a share. You get the price exposure, but you do not own any coins, hold any keys or control any wallet. Because it is a listed security rather than a cryptoasset, an ETN can sit inside mainstream investment accounts in a way raw crypto cannot.
Bear in mind these remain high-risk products. The FCA has been clear that crypto remains largely unregulated and that investors should be prepared to lose all their money.
How we got here: October 2025 to April 2026
In October 2025 the FCA lifted its long-standing ban on retail access to crypto ETNs, opening these products to ordinary UK investors for the first time since 2021. For a period, crypto ETNs could be bought and held within stocks and shares ISAs, giving investors tax-sheltered crypto exposure.
That window proved short. From 6 April 2026 the rules changed: crypto ETNs were reclassified so that, going forward, they sit within the Innovative Finance ISA category rather than the stocks and shares ISA. In practice, platforms stopped allowing new purchases or top-ups of crypto ETNs within stocks and shares ISAs from that date.
Where that leaves you now
Based on the position at the time of writing:
- Existing holdings: platforms have generally confirmed that crypto ETNs bought in a stocks and shares ISA on or before 5 April 2026 can remain there and can be sold at any time, though they cannot be added to within that ISA. Confirm this with your own provider, as implementation can vary.
- New purchases: the route now runs through the Innovative Finance ISA, and availability depends on whether your provider offers crypto ETNs within one.
- The future: the government has indicated it will keep the treatment of crypto ETNs in tax-advantaged accounts under review, so the position could change again.
Check before acting. This is a fast-moving area. Before buying, selling or transferring anything, check the current rules on gov.uk and with your ISA provider, because articles date quickly when rules move this fast.
Crypto outside an ISA: the tax reality
If you hold coins directly, they sit outside any ISA wrapper, which means tax applies in the normal way. HMRC treats cryptoassets as chargeable assets, so selling, swapping or spending them can trigger Capital Gains Tax, and with the annual exempt amount now just £3,000, even modest gains are reportable. Staking and similar activity can be subject to Income Tax instead. And HMRC increasingly sees this activity, as we explain in our guide on whether HMRC can track crypto.
That makes planning worthwhile: using allowances, keeping proper records and understanding when tax falls due. A conversation with a specialist crypto tax accountant UK investors trust can save you real money and real stress. You will find more common questions answered in our crypto FAQ.
Frequently asked questions
Can I put Bitcoin directly into an ISA?
No. Cryptocurrencies themselves are not ISA-qualifying investments, so you cannot hold coins or tokens directly in any ISA. Exposure has only been possible through listed products such as crypto ETNs, and the rules on those have changed.
Can I still buy crypto ETNs in a stocks and shares ISA?
Based on the position at the time of writing, no. New purchases within stocks and shares ISAs stopped from 6 April 2026, with crypto ETNs instead treated as Innovative Finance ISA investments. Check the current rules with your provider before acting.
What happens to crypto ETNs I bought in my ISA before April 2026?
Platforms have generally confirmed that holdings bought on or before 5 April 2026 can remain in the stocks and shares ISA and be sold at any time, though you cannot add to them there. Confirm the position with your own provider.
What is a crypto ETN?
An exchange-traded note is a listed debt security that tracks the price of an asset such as Bitcoin. You get price exposure through a stockbroker account, but you do not own the underlying coins. The FCA regards these as high-risk investments.
Is crypto held outside an ISA taxable?
Yes. Crypto held directly is a chargeable asset, so disposals above the £3,000 annual exempt amount can trigger Capital Gains Tax, and activities like staking can be subject to Income Tax.
