Carried interest is the reason this newsletter is called The Carry. It's the slice of the profit a fund manager or syndicate lead earns when the deals they ran come good - their reward for sourcing, structuring and shepherding other people's money into companies that work out. For years it was taxed as a capital gain. From 6 April 2026 it isn't.
The change matters to a specific group of readers: the people running syndicates and small funds, not the solo angel writing cheques into their own portfolio. If that's you, the headline is straightforward and the detail is where the work sits. Here's what moved, and how the new treatment is built.
Carry used to be a capital gain. From April 2026 it's income.
What carried interest actually is
Start with the thing being taxed. When a syndicate or fund makes money, the people who put up the capital get their money back plus an agreed return. After that, a share of the remaining profit goes to whoever ran the vehicle - the lead, the general partner, the manager. That share is the carried interest, usually shortened to carry, and a 20% carry is the long-standing reference point.
The key point is whose money generated it. Carry is a performance reward on other people's capital. A solo angel who invests their own money and sells at a profit isn't earning carry; they're realising a gain on their own holding, taxed in the ordinary way. Carry only arises where you're managing money for others and taking a cut of the upside, typically after the members have had their capital and a set return back first. That distinction decides whether any of this applies to you, and it's the single thing to settle before reading another word of the new rules.
The old treatment and the new
Under the rules in place before 6 April 2026, carried interest was generally treated as a capital gain and charged at capital gains tax rates. The logic was that the lead's reward tracked the growth in the underlying investments, so it looked and behaved like an investment return rather than a wage.
From 6 April 2026 that framing is gone. Carried interest is now taxed as trading income - it falls within income tax and also attracts Class 4 National Insurance contributions, the NIC band that applies to self-employed trading profits. The government set out the change in its reform of the tax treatment of carried interest. In plain terms, what was an investment gain is now treated as earnings from running the fund.
The multiplier and the qualifying rate
The new regime isn't a flat charge of full income tax and NIC on the whole sum. There's a relief built in for what the rules call qualifying carried interest. Where carry qualifies, only 72.5% of it is brought into the income tax and NIC charge - a 72.5% multiplier applied before the tax is worked out.
Run that through the top rates and the effective top rate on qualifying carry lands at around 34.075%. That's higher than capital gains rates were, but well below the full marginal cost of treating every pound as ordinary earnings. Whether carry qualifies turns on how long the underlying investments were held: the full treatment needs a weighted-average holding period of roughly 40 months, with partial relief phasing in from around 36 months. The average is weighted across the deals that produced the carry, so a portfolio that exits quickly can fall short while a patient one clears the bar. Carry that fails the test doesn't get the multiplier, so the holding profile of a syndicate's deals now feeds directly into the lead's tax bill, and the timing of exits is no longer just a return question.
What it means for a syndicate lead
If you run a UK syndicate or you're building towards a small fund, the practical effects stack up. The tax on your carry is higher than it was under the capital-gains regime, the calculation is more involved, and the holding-period test means the timing of exits across the portfolio shapes what you eventually keep. National Insurance is now in the picture where it wasn't before, which changes the after-tax economics of the role.
None of that decides whether running a syndicate makes sense for you - that depends on your wider position, the structure of your arrangement and how it's documented. What it does mean is that carry is no longer a back-of-envelope number. The interaction of the multiplier, the qualifying test and your own marginal rates is exactly the sort of thing a specialist adviser earns their fee on, and the place to get it modelled is before an arrangement is set up, not after a distribution lands.
For the solo angel reading this: you can largely set it aside. The change is about carry on managed money. Your own gains on your own investments are taxed as they always were.
A note on what this isn't
This piece explains a rule; it doesn't tell you what to do about it. Carried interest sits close to regulated, fund-management territory, and the tax outcome depends heavily on how a particular arrangement is structured and documented - small differences in the terms can move the result. The figures here are the current headline mechanics, not a calculation for your situation, and they shift with each Budget. Confirm the position in HMRC's guidance on the reform of the tax treatment of carried interest, and take specialist tax and FCA-regulated advice before you act.
Frequently asked questions
How is carried interest taxed in the UK from 2026?
From 6 April 2026, carried interest is taxed as trading income rather than as a capital gain. That means income tax plus Class 4 National Insurance contributions. Where carry qualifies, a 72.5% multiplier applies before the charge is worked out, which brings the effective top rate to around 34.075%. The old capital-gains treatment no longer applies.
Does this affect solo angel investors?
No. Carried interest is a share of the profit on other people's money, earned by syndicate leads and fund managers for running the vehicle. A solo angel who invests their own capital and sells at a profit is realising their own gain, which is taxed in the ordinary way and is not affected by this change. The reform is about carry on managed money, not your own holdings.
What is the effective rate on qualifying carried interest?
Around 34.075% at the top. The rules apply a 72.5% multiplier to qualifying carry before income tax and Class 4 National Insurance are calculated, which is why the effective top rate sits below the full marginal cost of treating the whole amount as ordinary earnings. Carry that does not qualify does not get the multiplier.
What makes carried interest qualify for the lower rate?
It turns on how long the underlying investments were held. The full treatment generally needs a weighted-average holding period of roughly 40 months, with partial relief phasing in from around 36 months. Carry that does not meet the holding-period test is taxed without the 72.5% multiplier. The exact conditions depend on how the arrangement is structured, so confirm the current detail at GOV.UK.
Is this article tax advice for my syndicate?
No. This is general information about how the rules changed, not financial or tax advice for your situation. Carried interest sits in regulated, fund-related territory, the outcome depends on how each arrangement is structured, and the figures change with each Budget. Confirm the current position at GOV.UK and take specialist tax and FCA-regulated advice before acting.
