Recent policy developments have reinforced the importance of the Enterprise Investment Scheme (EIS) within the UK investment landscape.
From 6 April 2026, a series of structural changes have expanded the scope of EIS, allowing more capital to flow into growth businesses while maintaining the existing tax benefits for investors.
Alongside wider changes to capital gains tax (CGT) and inheritance tax (IHT) planning, EIS is becoming increasingly relevant for investors seeking both tax efficiency and access to high-growth private companies.
For a detailed overview of how EIS works and the tax reliefs available, see our guide to the Guinness EIS and EIS tax reliefs.
Key EIS Changes from 6 April 2026
The government has confirmed a number of enhancements to EIS, effective from 6 April 2026.
Increased company fundraising limits
- The annual amount a company can raise under EIS has increased from £5 million to £10 million
- The lifetime limit has increased from £12 million to £24 million
- For knowledge intensive companies, limits have risen from £10 million to £20 million annually, and from £20 million to £40 million over a lifetime
Expanded company eligibility
- The gross assets threshold have increased from £15 million to £30 million before investment
- The post-investment threshold have increased from £16 million to £35 million
These changes materially expand the universe of companies eligible for EIS investment, particularly those at a more advanced stage of growth.
This is one of the most significant updates to the Enterprise Investment Scheme rules in recent years.
No change to investor income tax relief
- Income tax relief remains at 30%
- The annual investment limit for individuals remains £1 million (or £2 million where at least £1 million is invested in knowledge intensive companies)
This stability is notable, particularly as VCT income tax relief has reduced from 30% to 20%, increasing the relative attractiveness of EIS for UK investors.
What These EIS Changes Mean in Practice
From a Guinness Ventures perspective, the changes do not alter the core investment philosophy, but they do improve the opportunity set.
Greater access to scaling companies
Higher funding limits allow EIS managers to invest in businesses that are further along their growth journey, often with stronger revenues and clearer paths to profitability.
Improved ability to support winners
Managers can deploy more follow-on capital into successful portfolio companies, rather than being constrained by historical limits.
Stronger deal pipeline
As companies can raise more EIS-eligible capital, the pool of investable opportunities is expected to broaden, particularly among scale-up businesses.
More efficient capital formation
Better funded companies are typically better positioned to execute expansion plans, including international growth, hiring and product development.
Wider Tax Changes Increasing EIS Relevance
Alongside the EIS enhancements, several broader UK tax changes are shaping investor behaviour.
Higher capital gains tax rates
Rates on most disposals have increased to 18% for basic rate taxpayers and 24% for higher rate taxpayers. This increases the relative attractiveness of EIS capital gains deferral relief.
Business Relief reform (from April 2026)
- 100% relief now applies to the first £2.5 million of qualifying business and agricultural property combined
- 50% relief applies above this level
- AIM shares qualify for 50% relief
These changes introduce greater structure to inheritance tax planning and may prompt investors to reassess how they access Business Relief.
Pensions and inheritance tax (from April 2027)
Unused pension funds and certain death benefits are expected to fall within the scope of inheritance tax from April 2027.
This represents a significant shift in long-term planning and may increase demand for alternative tax-efficient investment structures, including EIS.
The Role of EIS in Modern Investment Portfolios
EIS has always been positioned as a higher-risk, higher-return asset class. However, its role within portfolios is evolving.
Diversification
EIS investments are typically unquoted and may exhibit low correlation with public markets, offering diversification benefits alongside traditional asset classes.
Access to growth
Investors gain exposure to earlier-stage companies operating in sectors such as technology, healthcare and consumer innovation, which are often inaccessible through listed markets.
Tax efficiency
The combination of income tax relief, capital gains deferral, potential tax-free growth and inheritance tax advantages continues to underpin the appeal of EIS investments in the UK.

Risks and Considerations
EIS investments remain high risk and illiquid.
Capital is at risk and investors may lose some or all of their investment. Shares in unquoted companies are not readily realisable, and investment horizons are typically five years or longer.
Tax reliefs can help mitigate downside but do not eliminate risk. Suitability should always be assessed alongside an investor’s broader financial position and objectives.
Conclusion
The 2026 changes represent a clear signal of continued government support for the Enterprise Investment Scheme.
By increasing company limits and expanding eligibility, the scheme is being adapted to better reflect the funding needs of modern growth businesses.
At the same time, wider tax changes are increasing the relevance of tax-efficient investing more broadly.
In our view, EIS remains a compelling component of a diversified portfolio for investors who understand the risks and are seeking exposure to UK growth companies alongside tax efficiency.
