The Ultimate Guide to the Enterprise Investment Scheme (EIS)

Executive Summary

The Enterprise Investment Scheme (EIS) offers a powerful opportunity for early-stage businesses to attract investment while providing significant tax benefits to investors. Established in 1994, this government-backed initiative has become a cornerstone of UK business funding for startups and growing companies.

What is the Enterprise Investment Scheme?

The EIS is designed to help smaller, higher-risk companies raise finance by offering tax reliefs to individual investors who purchase new shares in these companies.

Key Benefits:

  • For businesses: Access to up to £5 million annually and £12 million lifetime funding
  • For investors: Tax reliefs including 30% income tax relief, capital gains tax exemption, and loss relief

Eligible Business Activities

Most trading activities qualify for EIS, with notable exceptions including:

❌ Property development or dealing
❌ Financial activities (banking, insurance, etc.)
❌ Legal or accounting services
❌ Energy generation
❌ Farming or market gardening
❌ Operating hotels or nursing homes
❌ Coal and steel production

Note: A company can conduct some excluded activities as long as they represent less than 20% of overall business operations.

How to Apply for EIS: Step-by-Step Process

1. Obtain Advance Assurance (Recommended)

Contact HMRC before issuing shares to confirm eligibility. This provides confidence to potential investors.

2. Issue Your Shares

Ensure compliance with all EIS requirements when structuring your share offering.

3. Submit a Compliance Statement (EIS1)

This can be done by:

  • Company Secretary
  • Director
  • Authorized Agent

4. Required Documentation:

  • Business plan and financial forecasts
  • Recent accounts
  • Explanation of risk to capital condition
  • Trading activity details
  • Memorandum and articles of association
  • Information provided to investors
  • Details of previous investments
  • Any relevant shareholder agreements

5. Timing Requirements:

  • Submit after 4 months of qualifying business activity
  • Must be within 2 years of this date or 2 years of tax year end in which shares were issued

Combining EIS with Other Funding Schemes

EIS can be used alongside other funding sources, but remember these limits:

  • Maximum £5 million total in any 12-month period from all state aid risk finance sources
  • Lifetime limit of £12 million (£20 million for knowledge-intensive companies)

Compatible schemes include:

  • Venture Capital Trusts (VCT)
  • Seed Enterprise Investment Scheme (SEIS)
  • Social Investment Tax Relief (SITR)
  • Other state aid approved under risk finance guidelines

Important Note: Once you’ve issued EIS shares, you cannot issue SEIS shares afterward.
