Venture investing is the corner of the financial world where the government says: “We know this is risky. We know a lot of these companies will fail. But we really need people to invest in small UK businesses, so here’s a massive tax break to make it worth your while.”
That’s the deal. Generous tax reliefs in exchange for backing early-stage, high-risk companies. The reliefs are so generous precisely because the risk is so real. If you get it right, the returns (plus the tax benefits) can be extraordinary. If you get it wrong, you lose money. Sometimes all of it.
This section covers VCTs, EIS, SEIS, Business Relief, and the other ways to invest in venture and early-stage companies in the UK. All figures are for the 2026/27 tax year, which brought significant changes to several of these schemes.
The Tax Relief at a Glance (2026/27)
| VCT | EIS | SEIS | |

¹ Reduced from 30% to 20% from 6 April 2026
² Up to 2,000,000 if at least 1,000,000 goes to knowledge-intensive companies (KICs)
³ If held for 3+ years and income tax relief was claimed
⁴ 50% of the reinvested gain is exempt from CGT
⁵ After 2 years via Business Relief. From April 2026, 100% BR on private companies capped at 2.5M combined with agricultural property, then 50% above
⁶ VCTs invest in a portfolio of 30-80+ companies. Built-in diversification
⁷ Individual company risk unless using a managed EIS/SEIS fund
VCTs (Venture Capital Trusts)
A VCT is a company listed on the London Stock Exchange that invests in a portfolio of small, unquoted (or AIM-listed) UK companies. Think of it as a fund that pools your money with other investors and spreads it across 30-80+ early-stage businesses.
How VCTs Work
- You buy newly issued shares in the VCT
- The VCT manager selects and manages a portfolio of qualifying companies
- You get income tax relief on your investment
- Dividends are paid from successful exits and portfolio income
- VCT shares trade on the stock exchange (but liquidity is thin)
Tax Benefits (2026/27)
- 20% income tax relief on new shares (reduced from 30% from 6 April 2026). Invest 10,000, get 2,000 off your income tax bill
- Tax-free dividends from the VCT
- Tax-free capital gains when you sell VCT shares
- 5-year minimum hold to keep the income tax relief. Sell before 5 years and you repay it
- Relief only on newly issued shares, not secondary market purchases (buying existing VCT shares on the stock exchange gets you the tax-free dividends and gains but no income tax relief)
The Reduction from 30% to 20%
This is the big change for 2026/27. VCT income tax relief dropped from 30% to 20% on 6 April 2026. This has made VCTs relatively less attractive compared to EIS (still 30%) and SEIS (still 50%). Many investors rushed to invest before April 2026 to lock in the higher rate.
At 20%, VCTs still offer tax-free dividends and tax-free gains, which remain valuable for income-seeking investors. But the upfront tax relief is now less compelling than EIS for those with the risk appetite for direct company investment.
Types of VCT
- Generalist VCTs invest across sectors in a range of early-stage and growth companies. The broadest diversification
- AIM VCTs focus on companies listed on the AIM market. More liquid holdings but still small, volatile companies
- Specialist VCTs concentrate on specific sectors like technology, healthcare, or renewable energy
Major VCT Managers
| Manager | Notable VCTs | Style |
|---|---|---|
| Octopus | Titan VCT | Largest generalist VCT. Tech-focused |
| Albion | Albion VCTs (4 VCTs) | 30-year track record. Diversified |
| Gresham House | Baronsmead VCTs, Mobeus VCTs | Established. Mix of legacy and new |
| Maven | Maven VCTs | Regional focus. Smaller companies |
| Foresight | Foresight VCTs | Sustainability and infrastructure tilt |
| Downing | Downing VCTs | Diversified. Active manager |
| ProVen | ProVen VCTs | Beringea. Growth-stage companies |
| Northern | Northern VCTs | Focus on Northern England. Regional |
Octopus Titan is the largest, with regular oversubscribed fundraises. Albion has delivered roughly 6.5% average annual returns over five years (before tax relief). Performance varies significantly between managers and vintages.
VCT Dividends: The Income Play
Many VCTs target regular dividends of 4-6% per year, paid from a combination of portfolio income and profitable exits. Because VCT dividends are tax-free, a 5% VCT yield is equivalent to a much higher gross yield for a 40% or 45% taxpayer.
For a higher-rate taxpayer, a 5% tax-free VCT dividend is equivalent to roughly 8.3% gross from a taxable investment. For an additional-rate taxpayer, it’s equivalent to roughly 9.1%. That’s a meaningful income advantage.
Risks
- You’re investing in small, early-stage companies. Many will fail
- VCT shares are relatively illiquid. The secondary market is thin, and you may have to sell at a discount to NAV
- Past performance varies wildly between managers
- The 5-year lock-in means your capital is tied up
- Tax relief doesn’t turn a bad investment into a good one. If the underlying companies fail, you still lose money (just less of it)
EIS (Enterprise Investment Scheme)
EIS allows you to invest directly in qualifying small UK companies and receive significant tax reliefs. Unlike VCTs (where a manager builds a portfolio for you), EIS puts you into individual companies. Higher potential returns, higher risk, and no diversification unless you build it yourself or use an EIS fund.
Tax Benefits (2026/27)
- 30% income tax relief on investments up to 1,000,000 per year (2,000,000 if at least 1,000,000 goes to knowledge-intensive companies). Invest 50,000, get 15,000 off your tax bill
- CGT deferral on gains reinvested into EIS. You can defer a capital gain from selling any asset by reinvesting the proceeds into EIS shares. The deferred gain becomes payable when you sell the EIS shares
- CGT-free gains if the EIS shares are held for 3+ years and income tax relief was claimed
- Loss relief if the company fails. The net loss (after income tax relief) can be offset against either income tax or CGT. This significantly limits downside
- IHT exemption after 2 years through Business Relief
- Carry back income tax relief to the previous tax year
The Loss Relief Safety Net
This is the bit that makes EIS genuinely clever as a tax planning tool.
You invest 10,000 in an EIS company. You get 3,000 income tax relief (30%). Your net cost is 7,000. The company fails and the shares are worthless.
You can now claim loss relief on the 7,000 loss. As a 45% taxpayer, that’s worth 3,150 in tax relief.
Total tax reliefs: 3,000 + 3,150 = 6,150. Your actual loss on 10,000 invested is just 3,850. The government absorbed over 60% of the downside.
Of course, you still lost 3,850. But the risk is dramatically reduced compared to investing without EIS relief.
Qualifying Criteria (2026/27)
The company must be:
- UK-based (or with a permanent UK establishment)
- Fewer than 250 employees
- Gross assets under 15 million (before investment), 16 million (after)
- Less than 7 years old (10 for knowledge-intensive companies)
- Not listed on a main stock exchange (AIM is allowed)
- Lifetime fundraising limit: 24 million (increased from 12 million from April 2026), or 40 million for KICs (up from 20 million)
EIS Funds vs Direct EIS
Direct EIS: you invest in a single company. Maximum potential return (and maximum risk). You choose the company (or your adviser does). Best for experienced investors who understand the specific business.
EIS Funds (Managed Portfolios): a fund manager selects a portfolio of 5-15+ EIS companies on your behalf. Spreads risk across multiple businesses. You get diversification but pay a management fee (typically 1-2% initial, plus ongoing). Major EIS fund managers include:
- Octopus Investments (one of the largest EIS managers)
- Oxford Capital (technology and innovation focus)
- Downing (diversified EIS funds)
- Parkwalk (university spin-outs)
- Mercia (regional, tech-focused)
- SyndicateRoom (co-investment alongside professional angels)
- Seedrs (equity crowdfunding platform, some EIS-qualifying deals)
- IW Capital (growth-stage companies)
Risks
- You’re investing in individual small companies. The failure rate is genuinely high
- Highly illiquid. There is no secondary market. Your money is locked in until a sale, IPO, or failure
- Typical hold periods are 5-10 years, sometimes longer
- Tax reliefs exist BECAUSE the risk is high. Don’t be seduced by the tax break alone
- Due diligence on individual companies requires expertise most retail investors don’t have
SEIS (Seed Enterprise Investment Scheme)
SEIS is EIS’s younger, smaller, riskier sibling. It targets the very earliest stage of company development: seed-stage startups that are just getting off the ground. The tax reliefs are the most generous of any UK investment scheme because the risk is the highest.
Tax Benefits (2026/27)
- 50% income tax relief on up to 200,000 per year. Invest 10,000, get 5,000 off your tax bill
- 50% CGT reinvestment relief on gains reinvested into SEIS. Reinvest a 20,000 capital gain into SEIS and 10,000 of that gain is exempt from CGT
- CGT-free gains if held for 3+ years
- Loss relief if the company fails (same mechanism as EIS)
- IHT exemption after 2 years through Business Relief
Qualifying Criteria
- Company must be under 3 years old
- Fewer than 25 employees
- Gross assets under 350,000
- Lifetime SEIS fundraising limit: 250,000 per company
The Downside Protection Calculation
SEIS downside protection is extraordinary.
Invest 10,000. Get 5,000 income tax relief (50%). Net cost: 5,000. Company fails.
Loss relief on 5,000 at 45%: 2,250.
Total reliefs: 5,000 + 2,250 = 7,250. Your actual loss: 2,750 on a 10,000 investment. The government absorbed 72.5% of the downside.
That’s remarkable. But you still lost 2,750. And most seed-stage startups fail. The maths only works if some of your portfolio companies succeed spectacularly enough to compensate for the many that don’t.
SEIS Platforms and Providers
- Seedrs (now part of Republic) and Crowdcube offer SEIS-qualifying deals through equity crowdfunding
- SyndicateRoom offers curated SEIS co-investments
- Angel investor networks and accelerators (Techstars, Entrepreneur First, SeedLegals) often facilitate SEIS investment
- Many SEIS investments are made through personal networks and angel groups rather than managed funds
Business Relief (BR) and AIM Investing
Business Relief (formerly Business Property Relief) is an inheritance tax relief that can reduce or eliminate IHT on qualifying business assets. It’s not a venture capital scheme in the same way as VCT/EIS/SEIS, but it’s closely related and often used alongside them for IHT planning.
How BR Works
If you hold qualifying business assets for at least 2 years at death, they can qualify for IHT relief. The relief reduces the IHT-taxable value of those assets.
Major Changes from April 2026
The Autumn Budget 2024 fundamentally changed BR. Here’s the new landscape:
Private (unquoted) company shares:
- 100% relief up to a combined 2.5 million allowance (shared with agricultural property relief)
- 50% relief above 2.5 million (effective IHT rate of 20% on the excess)
- Unused allowance can transfer to a surviving spouse/civil partner, so a couple can protect up to 5 million at 100%
AIM-listed shares:
- Now only qualify for 50% relief (down from 100%)
- Do NOT count towards the 2.5 million 100% allowance
- This means AIM shares held for IHT planning now face an effective 20% IHT rate regardless of value
- A significant blow to the popular “AIM for IHT” strategy
EIS and SEIS shares:
- Qualify for 100% BR after 2 years (as private company holdings)
- Count towards the 2.5 million combined allowance
AIM Portfolios for IHT Planning
Before April 2026, many investors held AIM-listed shares specifically for IHT planning: hold them for 2 years, and they qualified for 100% BR, effectively passing outside your estate for IHT purposes.
The reduction to 50% relief makes this less powerful. A 500,000 AIM portfolio previously passed IHT-free. Now it faces a potential 50,000 IHT bill (20% effective rate). Still better than the full 40% on a standard portfolio, but the advantage has halved.
Providers offering AIM portfolio services for BR/IHT include:
- Octopus (AIM Inheritance Tax Service)
- Downing (AIM Estate Planning Service)
- Puma (AIM IHT portfolios)
- Blackfinch (Adapt IHT portfolios)
- Time Investments (AIM portfolio service)
Interest-Free Instalments
From April 2026, where IHT is payable on BR/APR qualifying assets, it can be paid in up to 10 equal annual instalments, interest-free. This is new and helpful for estates with illiquid business assets.
Other Venture Investing
Beyond the tax-advantaged schemes, there are other ways to invest in early-stage and private companies:
Equity Crowdfunding
Platforms like Crowdcube and Seedrs allow you to invest small amounts (from 10 upwards) into startups and growth companies. Many deals qualify for EIS or SEIS relief. You browse pitches, review business plans, and decide where to invest.
- Low minimum investment makes it accessible
- Wide range of sectors and stages
- Many deals include EIS/SEIS tax relief
- Highly illiquid. No secondary market for most investments
- Failure rates are high. Most crowdfunded companies will not return your capital
Angel Investing
Direct investment in startups, typically at seed or pre-seed stage. Angel investors usually invest 5,000 to 100,000+ per company and often take an active role (mentoring, introductions, board seats).
- Usually qualifies for SEIS or EIS relief
- Requires significant expertise to assess companies
- Angel networks and syndicates (Angel CoFund, Cambridge Angels, London Business Angels) pool knowledge and capital
- Very high risk, very long time horizons (7-10+ years to exit)
Private Equity Funds
For larger investors (typically 100,000+ minimum), private equity funds invest in established private companies or buyouts. These don’t usually qualify for EIS/SEIS/VCT relief but can offer strong returns for patient capital.
- Long lock-up periods (7-12 years)
- Limited liquidity
- High minimum investment
- Institutional-grade due diligence
- Available through some SIPPs via Long-Term Asset Funds (LTAFs)
Who Should Consider Venture Investing?
Venture investing is NOT for beginners, and it’s NOT a substitute for a diversified portfolio of mainstream investments. It should sit at the edge of a well-built portfolio, not at the centre.
Good candidates:
- Higher-rate or additional-rate taxpayers who can use the income tax relief
- Investors with a substantial existing portfolio who can afford to lose the money entirely
- People with a genuine interest in and understanding of early-stage businesses
- Those with an IHT planning need (particularly EIS/SEIS for BR)
- People with recent capital gains who want to defer CGT (EIS CGT deferral)
Not suitable for:
- Anyone who can’t afford to lose the entire investment
- Investors who need liquidity within the next 5-10 years
- People investing primarily for the tax relief rather than the underlying opportunity
- Anyone who hasn’t maximised their pension and ISA allowances first
The Bottom Line
Venture investing offers the most generous tax reliefs in the UK investment landscape. Those reliefs exist because the risk is real and the failure rate is high.
The 2026/27 tax year brought meaningful changes: VCT relief dropping to 20%, BR capped at 2.5 million for 100% relief, and AIM shares reduced to 50% relief. EIS at 30% and SEIS at 50% remain unchanged and arguably look more attractive relative to VCTs than before.
The golden rule: never let the tax tail wag the investment dog. A 50% tax break on a terrible investment is still a loss. Start with the quality of the underlying business, then appreciate the tax relief as a bonus.
And always, always invest only money you can genuinely afford to never see again. Because with venture investing, that’s a real possibility.
