Guide to EIS Investments: Tax Relief, Risk, and How to Invest
The Enterprise Investment Scheme (EIS) is one of the most generous tax incentives in the UK's investment landscape. Launched in 1994, it was designed to channel private capital into small and growing businesses that struggle to access mainstream finance. For higher and additional rate taxpayers, the combination of upfront income tax relief, capital gains tax deferral, inheritance tax exemption, and loss relief creates a compelling financial case — provided the underlying investments are selected with care.
This guide explains how EIS works in practice, how to access it, and how to weigh the significant risks against the tax advantages.
What is EIS?
EIS is a government-backed scheme that provides tax relief to individuals who invest in qualifying small, unquoted companies. The relief is intended to compensate investors for the elevated risk of early-stage investing. HMRC administers the scheme, and companies must obtain advance assurance before raising EIS funds.
To qualify, a company must be:
- Unquoted (not listed on the main stock exchange; AIM-listed shares can sometimes qualify)
- UK-based or carrying on a qualifying trade in the UK
- Fewer than 250 full-time employees (or 500 for knowledge-intensive companies)
- No more than £15 million in gross assets (£16 million after the investment)
- Raising no more than £5 million in total in any 12-month period (£10 million for knowledge-intensive companies)
Certain sectors are excluded: financial services, property development, legal services, hotels, and farming among others. The scheme is biased towards genuinely commercial, growth-oriented businesses.
The Four Tax Reliefs
1. Income Tax Relief: 30%
Investors receive a 30% income tax reduction on investments up to £1 million per tax year (£2 million if the additional amount is in knowledge-intensive companies). The relief is a reduction in your income tax bill, not merely a deduction from taxable income.
An investor subscribing £100,000 into EIS-qualifying shares reduces their income tax liability for that year by £30,000. This is not a refund — you must have sufficient income tax liability to absorb the relief. Any unused relief cannot be carried forward (though investments can be carried back to the prior tax year — see below).
The shares must be held for at least three years. If you dispose of them within three years, HMRC claws back the income tax relief pro rata.
2. Carry-Back Provision
EIS subscriptions can be treated as though they occurred in the previous tax year. This is valuable if:
- You had a higher income tax bill last year and want to reduce it
- You had a chargeable event or bonus in the prior year
- You want to use relief against income from a year already closed
You can carry back up to the full investment amount (subject to the annual limits). To use this, you must claim on your self-assessment return or write to HMRC.
3. Capital Gains Tax Deferral
EIS allows you to defer a capital gain of any size by reinvesting the gain proceeds into EIS-qualifying shares within one year before or three years after the disposal. The gain is deferred until:
- You dispose of the EIS shares, or
- You cease to be UK-resident, or
- Three years after the EIS shares were issued (whichever is earlier)
The deferred gain comes back into charge at your prevailing CGT rate at that point, not at the historical rate. This is therefore a deferral tool, not an exemption — but it can be used repeatedly to roll gains forward almost indefinitely.
Example: a £500,000 CGT liability deferred into EIS shares also attracts 30% income tax relief on the subscription (reducing the net outflow by £150,000), and the deferred gain continues to roll if the EIS shares are reinvested into another qualifying company on disposal.
4. IHT Exemption (Business Property Relief)
EIS-qualifying shares are typically unlisted trading company shares, which attract Business Property Relief (BPR) at 100% after two years of ownership — up to a combined BPR/APR allowance of £2.5 million per individual (from 6 April 2026). Assets above that threshold receive 50% relief. This means the shares can sit outside your estate for IHT purposes after a two-year holding period, subject to those limits.
For investors with estates over the nil-rate band, EIS investments that have been held for two or more years can be substantially inheritance tax-free within the BPR allowance. This is a significant additional benefit for estate planning purposes.
Note: the BPR exemption is not automatic — it depends on the company continuing to be a qualifying trading company. Companies that become investment companies or cash-rich shells lose BPR. This must be monitored.
5. Loss Relief
If an EIS investment fails (which is statistically likely in early-stage investing), the net loss after income tax relief can be set against income or capital gains. This is called EIS loss relief.
Example: £100,000 invested; 30% income tax relief received (£30,000); company fails completely. Net cost = £70,000. Loss relief on the £70,000 at 45% income tax rate = £31,500. Net total loss = £38,500. The effective downside is therefore substantially cushioned compared to an unrelieved loss.
EIS Funds vs Direct Investment
Direct Investment
Investing directly into a single EIS company gives maximum control and potentially maximum return — but concentrates risk entirely in one business. Direct EIS investment is appropriate for:
- Angel investors with sector expertise
- Individuals who know the founder/management team personally
- Those who can monitor the investment closely
Most sophisticated individual EIS investors spread across five to ten companies to diversify.
EIS Funds
EIS fund managers deploy capital across a portfolio of qualifying companies, typically 10–25 businesses. The tax relief flows through to individual investors. Funds are managed by FCA-authorised investment managers and provide:
- Diversification across multiple investments
- Professional due diligence on each company
- Portfolio management and follow-on investment decisions
- Regular investor reporting
EIS funds charge management fees (typically 1.5–2.5% per annum) and carry (a performance fee of 20–25% of profits above a hurdle). The fund structure may also mean a single EIS3 certificate covering the whole portfolio rather than individual certificates per company.
Well-known EIS fund managers include Octopus Investments, Parkwalk Advisors, Deepbridge Capital, and Mercia Asset Management.
EIS Portfolios (Unmanaged)
Some platforms allow investors to build a self-selected portfolio of EIS opportunities. Platforms such as Seedrs, Crowdcube (for smaller tickets), and Wealth Club provide curated deal flow. The investor makes individual decisions but has access to pre-vetted opportunities.
How to Find Qualifying Companies
Qualifying EIS investments can be sourced through:
- EIS Association (EISA): the industry trade body; its website lists regulated fund managers
- FCA-regulated platforms: Wealth Club, SyndicateRoom, Growthdeck
- Angel networks: UK Business Angels Association (UKBAA), local angel groups
- Accountants and wealth managers: many have curated EIS deal flow
- Crowdfunding platforms: Seedrs and Crowdcube host some EIS-eligible raises at smaller ticket sizes
Always verify that the company has received HMRC advance assurance before investing. The EIS3 certificate (confirming eligibility) is issued by HMRC after the investment, typically three to four months after the close of the fundraising round. Relief can only be claimed once the EIS3 is received.
The Worked Example: Combined Tax Advantage
Consider an additional rate (45%) taxpayer who has a £200,000 capital gain from selling a business asset (attracting CGT at 24% for higher/additional rate taxpayers — £48,000 of CGT), and invests £200,000 into an EIS fund.
| Item | Amount |
|---|---|
| Investment | £200,000 |
| Income tax relief (30%) | (£60,000) |
| CGT deferral on £200,000 gain | (£48,000 CGT deferred) |
| Effective net outflow (year 1) | £92,000 |
If the EIS portfolio grows at 2× over five years:
- Portfolio value: £400,000
- No CGT on the growth (CGT-exempt on EIS gains)
- Deferred gain crystallises: £48,000 at prevailing CGT rate
- Net profit: substantially positive
Even if the portfolio returns nothing:
- Net cost after income tax relief: £140,000
- Loss relief at 45%: £63,000 (45% of £140,000 net loss)
- Total maximum loss: £77,000 on a £200,000 commitment
Key Risks
EIS investing involves backing early-stage, often pre-profit businesses. The risks are substantial:
- Illiquidity: EIS shares cannot be listed on a main exchange. There is no guaranteed secondary market. You may be unable to sell for many years.
- Total loss: a meaningful proportion of early-stage companies fail entirely.
- HMRC compliance risk: if the company breaches EIS conditions, reliefs may be withdrawn.
- Valuation opacity: unlike listed equities, EIS companies are privately valued, and portfolio valuations may not reflect market reality until a liquidity event.
- Manager risk: fund managers vary enormously in quality; past performance in this sector has limited predictive value.
EIS is most appropriate for investors who: have maximised pension and ISA allowances; have a clear CGT liability to defer or shelter; are comfortable with a minimum five-year horizon; can accept the possibility of total loss; and are in the 40% or 45% tax bracket.
Practical Considerations
- Self-assessment: EIS relief must be claimed on your tax return. Retain EIS3 certificates.
- Non-UK residents: UK non-residents can invest in EIS but receive income tax relief only if they have UK income tax liability in the relevant year.
- Annual limits: £1 million (£2 million for knowledge-intensive companies) per individual per tax year.
- Joint investors: each spouse/civil partner has their own separate EIS limit.
- Pension and ISA interaction: EIS does not sit within a pension or ISA wrapper — it stands alone.
As of 2026, the EIS scheme has been confirmed by the government as a permanent feature of the UK tax code, with the sunset clause originally proposed for 2025 having been extended indefinitely for knowledge-intensive companies and removed for mainstream EIS.
