Since 6 April 2026, new crypto ETN purchases no longer qualify for stocks and shares ISAs — only the Innovative Finance ISA. Existing holdings can stay. Here's how the rules work now and what your options are.
Important Risk Warning
This is not financial advice. Cryptocurrency investments are highly volatile. The value of your investment can go down as well as up, and you could lose all the money you invest. Don't invest unless you're prepared to lose all the money you put in.
London — For six months, UK investors could buy bitcoin and ether exchange-traded notes inside a stocks and shares ISA and shelter the gains from tax entirely. That window closed on 5 April 2026. Since the start of the new tax year, HMRC classifies crypto ETNs as qualifying investments only for the Innovative Finance ISA — a wrapper most investors have never opened and most platforms don't offer.
The result is one of the stranger corners of UK personal finance right now: a tax-free route for crypto exposure that exists on paper and barely exists in practice.
The FCA lifted its retail ban on crypto ETNs in October 2025, and London-listed products from major issuers became available to ordinary investors — including, initially, inside stocks and shares ISAs. Then came the tax-year reset. From 6 April 2026, crypto ETNs no longer qualify as new investments in a stocks and shares ISA; they qualify only for the Innovative Finance ISA (IFISA), the wrapper originally built for peer-to-peer lending.
CryptoUK, the industry trade body, summarised the move bluntly: the UK opened the door to crypto ETNs, then closed it through the tax system.
No. Holdings purchased on or before 5 April 2026 can stay in your stocks and shares ISA, and there's no forced sale. Gains on those grandfathered holdings remain tax-free inside the wrapper. What you can't do is add more — new purchases after that date have to sit outside the ISA, or inside an IFISA if you can find one that accepts them.
That second part is the catch.
In theory, yes. In practice, barely. When the reclassification was announced, none of the platforms authorised to offer Innovative Finance ISAs had plans to support crypto ETNs, and the mainstream investment platforms that do offer crypto ETNs — the ones where investors actually hold their ISAs — aren't IFISA managers. A handful of providers have signalled interest since, but if you walk into the market today expecting a smooth, tax-free crypto ETN purchase, you'll mostly find shrugs.
This will probably resolve itself — there's obvious demand, and platforms rarely leave demand unserved for long. But "probably, eventually" isn't a plan you can invest through today.
If you hold crypto ETNs bought before 6 April, the simplest move is often to leave them where they are; the wrapper keeps working for those units.
For new money, you've got three realistic routes. Buy crypto ETNs in a general investment account and accept capital gains tax exposure — remembering the annual CGT exempt amount is just £3,000, per HMRC. Wait for an IFISA provider to launch proper crypto ETN support and use next year's allowance there. Or hold direct crypto outside any wrapper, which carries the same CGT treatment plus self-custody decisions ISA investors usually prefer to avoid.
One more wrinkle worth knowing: the FCA proposed on 9 June 2026 to let authorised funds hold up to 10% in crypto ETNs. If that lands, ordinary funds inside your stocks and shares ISA could end up carrying modest crypto exposure anyway — through the front door of fund regulation rather than the side door HMRC just locked.
Two things. Whether any major IFISA manager launches crypto ETN support before the 2027–28 tax year, and whether the Treasury revisits the classification once the FCA's full crypto regime goes live in October 2027. Until then, keep records of what you bought and when — the 5 April 2026 line now divides your tax-free holdings from everything else, and HMRC will care about which side each unit sits on.
