UK Business Secretary Rules Out Spinout Exit Tax After Investor Backlash Over University Equity Stakes

For a few days this week, investors backing Britain's university spinouts were bracing for a levy that would have taxed them on the way out. Rumours spread that the government was considering an exit tax on spinouts that sell to an overseas buyer or list outside the UK, payable on the uplift in value at that moment. Then business secretary Jonathan Reynolds moved to close the question down, telling business leaders privately that the tax would not go ahead. A figure at the Department for Business and Trade went further to the Financial Times, calling the idea unequivocally ruled out and saying the government preferred to compete on environment and incentives rather than penalties.

The relief was audible. But the debate that produced it points to a structural question about spinout equity that the tax decision alone does not resolve, and that the emerging infrastructure around tokenised equity and PISCES is well placed to help answer.

Why the rumour landed so hard

University spinouts already give up a meaningful slice of the company before they have raised a penny of external capital. Jamie Macfarlane, cofounder of spinout investor Creator Fund, put the current arrangement bluntly: universities are taking five, ten, fifteen or twenty per cent of a company on day zero when a spinout happens, a stake justified as reimbursement for the institutional support behind the research. Layer an exit tax on top of that, he argued, and founders and their backers would effectively be paying twice, once in equity handed over at formation and again in tax on the value they eventually create.

An LSE and Centre for the Analysis of Taxation report had urged an exit tax as a way to keep the benefits of publicly funded research inside the UK. Startup Coalition took the opposite view, gathering an open letter signed by more than 150 entrepreneurs opposing the idea. Moray Wright, chief executive of prominent spinout investor Parkwalk Advisors, warned that an exit tax could prove very challenging to implement and, if the goal was to stop companies leaving, could have the opposite effect by dampening investor appetite for backing early stage ventures in the first place.

What is actually changing

The government's decision to rule out the tax is a genuine, if narrow, win for spinout investors and the founders who depend on them. It also reflects something broader: a growing recognition across UK venture that the way to keep high growth, research backed companies anchored in Britain is not to punish them for leaving, but to make staying and scaling here more attractive than the alternative.

That reframing is already visible in how spinout investors are behaving. Northern Gritstone, which backs spinouts across the north of England, opened a San Francisco office earlier this year specifically to pull US capital into its portfolio rather than watch its companies chase that capital abroad. Chief executive Duncan Johnson argued the UK needs to be realistic about where it sits on the venture capital journey, and that international expansion should not be treated as being at odds with domestic wealth creation.

Companies need access to markets like the US, he said, and international investors need not mean international headquarters.

Ale Maiano, cofounder of pre-seed investor Wilbe, which backs scientist founders, made a related point about where the real leverage sits. Instead of reaching for more taxes, he said, the government could help spinouts by pushing universities to create more favourable environments for the companies they birth, starting with how much they spend on admin and overheads and how much their tech transfer offices secure in equity from the spinouts that come through them. That is a governance and incentive question, not a tax question, and it sits closer to the root of the frustration that the exit tax rumour tapped into.

The open question the tax decision does not answer

Ruling out an exit tax removes a punitive measure. It does not touch the underlying mechanic that generated the frustration in the first place: a spinout founder typically hands over a substantial equity stake to their university at formation, long before the company has proven anything, in exchange for support that is itself often hard to value precisely. That stake is illiquid for the university for years, and the founder carries the full dilution from day one regardless of how the company performs.

This is precisely the kind of structural friction that tokenised equity and PISCES trading windows were designed to address, not by changing how much equity a university takes, but by changing what both sides can do with that equity once it exists. A tokenised spinout cap table, reconciled properly against Companies House as the legal register of record, could in principle let a university's stake be held on a ledger that supports staged, regulated secondary sales through a PISCES venue once a company reaches a suitable maturity point, rather than sitting untouched until a full exit event years later. That would not shrink the initial stake. It would give the university a realistic route to realising some value earlier and more flexibly, which in turn could reduce the pressure to negotiate for a larger day zero stake to compensate for a long, uncertain wait.

Whether that is workable in practice, and on what terms, is genuinely open. It would require universities, tech transfer offices and their legal advisers to treat spinout equity as an asset that can be structured for eventual staged liquidity from the outset, not retrofitted later. It would also require PISCES operators and custodians to build comfort with university and public sector holders as participants, which is a different proposition from the founder and employee liquidity events PISCES has handled so far. Nothing here is settled, and nothing here is tax advice.

Where this leaves founders

Sifted's Tom Nugent is right that there is a bigger conversation to be had about getting the most out of the UK's base of academic founders, and that an exit tax was never going to be part of the answer. The government's decision this week removes a genuine threat. What it leaves in place is the quieter, more interesting question of whether the equity mechanics that spinouts have lived with for years can be modernised so that universities, investors and founders all get more out of the arrangement, without anyone needing a punitive tax to feel like the deal is fair.

Key takeaways

• The UK government has ruled out an exit tax on university spinouts that sell overseas or list abroad, following a backlash from spinout investors and a 150 signature open letter from Startup Coalition.

• Spinout investors argue the real friction is not exit taxation but the equity stakes universities already take at formation, often five to twenty per cent, before any external capital is raised.

• Northern Gritstone and other spinout backers are responding by pulling in international capital rather than treating overseas interest as a threat to be taxed.

• Tokenised equity and PISCES trading windows offer a genuinely open, unresolved route to giving universities staged liquidity on their spinout stakes without increasing dilution, though the custody and governance questions remain unanswered.

• Tokenising Startups is inviting tech transfer offices, spinout investors, PISCES operators and legal advisers to respond on whether staged tokenised liquidity for institutional equity stakes is workable.
