The door to tax-free crypto investing in the UK had, for all practical purposes, been shut since the start of this tax year. A regulatory quirk left investors with no viable platform to hold crypto products inside any individual savings account (ISA) at all. Now, a small start-up has quietly become the only way back in.
Stratiphy, a digital wealth management platform launched in August that currently manages £4 million on behalf of around 2,000 clients, this week became the first UK platform to offer both crypto exchange traded notes and the type of ISA, the Innovative Finance ISA, that the government now says is the only account eligible to hold them.
The launch, which went live Wednesday, gives investors a route to shelter crypto gains from capital gains tax for the first time under the new regulatory framework. To understand why that matters, a bit of background helps.
A short window that slammed shut
In October 2025, the Financial Conduct Authority, the UK’s financial regulator, lifted a four-year ban that had prevented retail investors from buying crypto exchange-traded notes (cETNs).
Exchange traded notes are financial instruments that track the price of an underlying asset, in this case cryptocurrencies like Bitcoin or Ethereum, without the investor needing to directly buy or hold the digital assets themselves. They trade on stock exchanges like regular securities and are issued by financial institutions rather than held in a wallet.
When the ban was lifted, HMRC initially confirmed crypto ETNs would be eligible for inclusion in stocks-and-shares ISAs, the mainstream tax-free investment accounts used by roughly 15 million Britons to invest in equities and funds each year without paying income tax or capital gains tax on returns. Investors have until April each year to deposit up to £20,000 into an ISA in a given tax year.
That window turned out to be brief. From April 6, 2026, the start of the new tax year, HMRC reclassified crypto ETNs as qualifying instruments only for the more niche Innovative Finance ISA, removing them from the mainstream stocks-and-shares wrapper.
The Innovative Finance ISA, or IFISA, was originally designed to give investors tax-efficient access to peer-to-peer lending, essentially matching savers with borrowers through fintech platforms, and is not a product that mainstream investment platforms typically offer.
The industry backlash was swift. George Bauer, Fidelity’s head of investment and product for global platform solutions, said the government’s approach “challenges the intention of allowing regulated access to crypto assets” and called on authorities to reconsider.
HMRC said it would keep crypto ETNs’ inclusion in tax-advantaged accounts under review, leaving open the possibility of reintroducing them into stocks-and-shares ISAs as the market matures and consumer understanding deepens.
But there was a more immediate problem than the policy debate. No UK platform at the time offered both crypto ETNs and Innovative Finance ISAs under one roof, meaning the new IFISA route existed on paper but not in practice. The tax-free path was, in effect, blocked entirely.
Stratiphy fills the gap
That’s where Stratiphy comes in. By obtaining authorization to offer both products simultaneously, the platform has broken what the FT called a “deadlock” in the market. Through the platform, investors can now access three ETNs issued by 21Shares, Europe’s largest issuer of crypto exchange traded products with $2.7 billion in assets, covering Bitcoin, Ethereum, and a combined Bitcoin-and-gold vehicle.
21Shares manages over $11 billion across 50 listed crypto products and has pointed to the surge in European crypto ETP trading, which reached €26 billion in 2024, representing 300 percent year-over-year growth, as evidence of appetite it expects to eventually replicate in the UK.
Daniel Gold, Stratiphy’s chief executive, described the launch as the only compliant route available to UK investors who want tax-efficient crypto exposure right now. The platform is primarily aimed at self-directed retail investors, business owners and corporate treasurers who want to build and test their own strategies, the platform offers AI-powered backtesting that shows how a portfolio would have performed over a decade of historical data.
The practical appeal is clear enough. Crypto is a volatile asset class that can generate substantial gains in short periods, and without a tax-efficient wrapper, those gains are subject to capital gains tax in the UK, which currently sits at 18 percent for basic-rate taxpayers and 24 percent for higher-rate taxpayers on investment gains above the annual exempt amount.
The catch investors should know
There is a meaningful risk embedded in this structure that investors should understand. Unlike stocks-and-shares ISAs, Innovative Finance ISAs are not covered by the Financial Services Compensation Scheme, the UK safety net that protects deposits and investments up to £85,000 if a regulated firm fails.
That protection does not extend to IFISAs, meaning the tax benefit comes with a trade-off in terms of investor protection. Crypto ETNs themselves also carry counterparty risk, they are unsecured debt instruments, so if the issuer fails, investors could lose their capital regardless of what happens to the underlying cryptocurrency’s price.
Still, for investors already holding crypto exposure through unregulated exchanges, a regulated ETN inside an IFISA arguably represents a step up in terms of oversight and structure, even if it falls short of the protections offered by a standard investment ISA.
The bigger picture question is whether this situation lasts. The industry clearly wants crypto ETNs back inside stocks-and-shares ISAs, and the government has at least said it may revisit the issue.
Hargreaves Lansdown, the UK’s largest investment platform, is expected to offer crypto ETNs by June, though like other mainstream platforms it has no current plans for an IFISA product. Until that regulatory position shifts, Stratiphy’s route remains the only tax-efficient entry point for new purchases.
