Understanding EIS Tax Relief

EIS tax relief is a venture capital scheme that encourages investment in smaller, higher risk companies, and also supports seis income tax relief by providing tax incentives that offset the risks of early stage business investing.

The Enterprise Investment Scheme allows individual investors to claim various tax reliefs when they subscribe for new shares in qualifying companies. Since its introduction in 1994, the scheme has channelled many billions of pounds into United Kingdom small and medium enterprises, creating a vital funding bridge for companies that often struggle to access institutional capital.

The government supports this scheme because it addresses the equity funding gap faced by innovative businesses while stimulating entrepreneurship and economic growth in key sectors including technology, life sciences, and advanced manufacturing.

Core Investment Limits

Annual investment limits determine the maximum relief available to individual investors. The standard limit is £1 million per tax year, allowing up to £300,000 in income tax relief. Investors can increase this to £2 million each year if at least £1 million is invested in knowledge intensive companies, potentially doubling the maximum income tax relief to £600,000.

These limits connect directly to relief calculations because all EIS tax benefits are proportional to the investment amount, subject to the investor’s available income tax liability.

Knowledge Intensive Companies

Knowledge intensive companies are businesses that meet specific research and development or innovation requirements, for example employing suitably qualified staff or conducting substantial research and development activities. Knowledge intensive status allows investors to access the increased £2 million annual limit described above potentially increasing the income tax relief available to investors depending on their income tax liability.

Note on excluded activities: energy generation activities are excluded from EIS. Focus on sectors that meet qualifying trade rules.

Income Tax Relief at 30%

EIS income tax relief allows an eligible investor to reduce their UK income tax liability by 30% of the amount invested in EIS qualifying companies. Example: a £10,000 EIS investment generates £3,000 in income tax relief. The maximum annual relief is £600,000 where the £2 million limit applies and at least £1 million is invested in knowledge intensive companies.

You can claim this relief in the investment tax year or carry it back to the previous tax year, subject to having enough income tax liability.

Capital Gains Tax Disposal Relief

Gains on the disposal of EIS shares are exempt from capital gains tax when you meet the minimum three year holding period and all qualifying conditions. Example: invest £50,000 and sell for £200,000 after three years; the £150,000 gain is free of capital gains tax.

Capital Gains Tax Deferral Relief

You can defer a capital gain from the disposal of any asset by subscribing for EIS shares where the shares are issued in the period beginning 12 months before and ending three years after the date the gain arose. There is no upper limit to the amount that may be deferred. The deferred capital gains tax becomes payable when you dispose of the EIS shares, or if the shares or company cease to qualify.

Loss Relief

If you dispose of EIS shares at a loss, you can set the net loss against income rather than only against capital gains. The loss is calculated after deducting any income tax relief received. You may claim against income of the year of disposal or the previous year.

Inheritance Tax Relief

EIS shares usually qualify for 100% Business Relief for inheritance tax once they have been held for at least two years and continue to meet the relevant conditions. This operates independently of the other EIS benefits and can form part of long term estate planning.

Key points

• Income tax relief at 30%, capped by your available tax liability
• Capital gains disposal relief, full exemption after three years where conditions are met
• Capital gains deferral relief with no upper monetary limit
• Loss relief against income on a net basis
• Inheritance tax Business Relief at 100% after two years where conditions are met

These rules are subject to change.

How to Claim EIS Tax Relief

The EIS tax relief claiming process has specific documentation and timing requirements, including the use of your paye tax code and involves both the company and the investor.

Step by step process

1. Company submits EIS1 compliance statement
   The company submits Form EIS1 to HM Revenue and Customs once it has carried on the qualifying activity for at least four months.
2. HM Revenue and Customs issues EIS2 and EIS3
   After review, HM Revenue and Customs issues Form EIS2 to the company and Form EIS3 to each investor. Timings vary and are not guaranteed.
3. Investor receives EIS3
   The EIS3 includes the unique investment reference and details required to claim relief.
4. Submit your claim
   Either include the EIS3 details in your Self Assessment tax return or ask HM Revenue and Customs to adjust the investors PAYE code to reflect the income tax relief.

Timing requirements

• The latest date to claim income tax relief and capital gains deferral relief is five years after 31 January following the end of the tax year in which the shares were issued.
• The minimum three year holding period applies to the main reliefs. If you dispose of shares or conditions are broken within that period, relief may be withdrawn and tax may become payable.

Self Assessment versus PAYE adjustment

• Self Assessment suits investors with multiple EIS investments or complex affairs because everything is reported in the annual return.
• PAYE code adjustment may be appropriate for employed taxpayers seeking to reflect relief sooner in the current tax year, once EIS3 details are available.

Common Challenges and Solutions

Important: This is general information only. It is not advice. Investors should seek professional advice from a qualified adviser before taking action.

Challenge 1: Insufficient income tax liability
If investors have insufficient income tax liability, a potential option is to use carry back to the previous tax year, subject to eligibility. Another option is to stage future subscriptions so they align with expected liabilities.

Challenge 2: Company loses qualifying status
If qualifying status is at risk, potential options are to monitor compliance through company updates, request confirmation from the company, and diversify across more than one EIS holding to reduce concentration risk. If status is lost within three years, some relief, including the income tax relief may be withdrawn.

Challenge 3: Early disposal of shares
If liquidity may be needed, a potential option is to plan before investing. Disposals within three years generally trigger withdrawal of income tax relief and block capital gains tax exemption. Loss relief may still be available where a genuine loss arises.

Conclusion and Next Steps

EIS can reduce investment risk through five complementary mechanisms that provide income tax reduction, capital gains protection, loss mitigation, and inheritance tax planning benefits. When properly used, these reliefs can save up to £600,000 each year while improving the risk return profile of venture investing.

To get started:

• Assess your annual income tax liability to determine an optimal EIS investment amount and claiming approach
• Research EIS qualifying companies or funds with strong compliance records and experienced management
• Consult a tax adviser, for example high value subscriptions or international tax considerations
