The UK offers two venture-capital tax regimes for individual investors (not companies):

1. Key Points at a Glance – SEIS vs EIS

  • SEIS
    • Designed for very early-stage companies.
    • Income-tax relief: 50% of the amount subscribed.
    • Personal subscription cap: £200,000 per tax year (limit doubled from April 2023).
    • Minimum holding period for CGT exemption: 3 years.
  • EIS
    • For early-growth companies (larger than SEIS targets).
    • Income-tax relief: 30% of the amount subscribed.
    • Personal subscription cap: £1 million, rising to £2 million where everything above £1 million is invested in knowledge-intensive companies (KICs).
    • Minimum holding period for CGT exemption: 3 years.

2. Seed Enterprise Investment Scheme (SEIS)

  • Investor reliefs
    • 50% income-tax relief on up to £200k per tax year.
    • No Capital Gains Tax (CGT) on gains after three years.
    • Re-invested capital gains can be sheltered.
    • Loss relief available if the start-up fails.
  • Company requirements
    • May raise up to £250k lifetime under SEIS.
    • Gross assets must not exceed £350k pre-investment.
    • Fewer than 25 full-time employees.
    • First commercial sale must be ≤ 3 years before the share issue (extended in 2023).

3. Enterprise Investment Scheme (EIS)

  • Investor reliefs
    • 30% income-tax relief on up to £1m (or £2m if excess goes into KICs).
    • CGT exemption after three-year holding period.
    • CGT deferral relief available on other gains reinvested.
    • Loss relief if the company under-performs.
  • Company requirements
    • Standard firms: may raise ≤ £5m in any 12-month period; £12m lifetime cap.
    • Knowledge-intensive companies: ≤ £10m per 12 months; £20m lifetime cap; up to 500 employees.
    • First commercial sale must be ≤ 7 years old (≤ 10 years for KICs).
  • Scheme duration
    • The EIS (and VCT) “sunset clause” has been extended to 6 April 2035.

4. Common Risk Considerations

  • Shares are illiquid; selling before three years normally cancels tax reliefs.
  • Tax benefits depend on both investor and company maintaining qualifying status.
  • Investing in start-ups is high-risk; capital is at risk and returns are uncertain.

5. Process Outline

  • Confirm personal eligibility (individual UK income-tax payer).
  • Company may obtain HMRC advance assurance.
  • Investor subscribes for new ordinary shares, fully paid in cash.
  • Company issues an SEIS 3 or EIS 3 certificate.
  • Investor claims relief through self-assessment; CGT reliefs applied on disposal or reinvestment.
