UK Startup Legal Checklist: EIS and SEIS Requirements Explained

Why EIS and SEIS Matter for UK Startups

SEIS and EIS let investors claim income tax relief and capital gains exemptions. In plain English: more cash in their pocket. That incentive equals more interest—crucial for tax-efficient startups looking to scale fast.

“Why bother?” you ask. Picture this: you’re at a fair. SEIS/EIS is the stall with free samples and discount vouchers. Who wouldn’t queue up?

Understanding SEIS

Seed Enterprise Investment Scheme (SEIS) is tailored for very early-stage ventures. Key perks:

  • Up to 50% income tax relief on investments (capped at £100,000 per investor)
  • 50% capital gains reinvestment relief
  • Loss relief up to 50% if things go south

Ideal for founders in garage-mode seeking first-wave supporters.

Understanding EIS

Enterprise Investment Scheme (EIS) suits slightly more established startups. Highlights:

  • 30% income tax relief on investments (up to £1 million per tax year)
  • Deferral of capital gains tax on gains re-invested into EIS-qualifying companies
  • Capital gains exemption after three years

A solid ramp-up for tax-efficient startups ready to climb.

No magic wand here. Just careful legal planning. Skip a step, and you risk losing benefits—or worse, HMRC scrutiny.

Eligibility Criteria

Qualifying Trading Activities

Your core business must be “qualifying.” This excludes:

  • Property development
  • Financial services
  • Farming or forestry

Focus on tech, education, manufacturing, and other innovation-driven fields. Perfect for tax-efficient startups in the Investment, Finance, or Technology sectors.

Company Age and Size

  • SEIS: Less than two years old.
  • EIS: Less than seven years old (or ten for “knowledge-intensive” firms).
  • Gross assets and employee headcount limits apply.

Share Structure and Investor Limits

Details matter:

  • New ordinary shares only.
  • Preference shares? Nope.
  • One class of shares for SEIS. Two classes allowed under EIS, but watch out for preferential rights.

Investors must hold shares for at least three years. Keep share certificates and board minutes tidy.

Advance Assurance from HMRC

Think of this as a pre-check. You send your pitch, financial forecasts, and company details. HMRC says “yes” or “no.” Not mandatory, but hugely comforting. No one likes surprises.

Here’s your cheat sheet. Tick these off and you’ll sleep better.

1. Incorporation and Structure

  • Register as a private limited company (Ltd).
  • File Articles of Association that don’t conflict with EIS/SEIS rules.
  • Confirm share capital structure complies.

2. Preparing Documentation

  • Detailed business plan: growth projections, use of funds.
  • Financial forecasts: realistic, not pie-in-the-sky.
  • Investor pitch: transparent and compliant.

3. Investor Agreements

  • Issue share subscription agreements.
  • Draft investor rights agreements.
  • Ensure all investors sign and date correctly.

4. Advance Assurance Application

  • Gather required documents: business plan, financial forecasts, Articles of Association.
  • Complete the HMRC form.
  • Send it off and wait (usually 6–8 weeks).

5. Post-Investment Compliance

  • File the Compliance Statement (SEIS1/EIS1) within two years of share issue (for SEIS) or by 5 April after the tax year (for EIS).
  • Provide investors with their certificates (SEIS3/EIS3).
  • Keep annual records and update HMRC if your circumstances change.

Every tick brings you closer to a smooth claim process. Like following a recipe—missing salt is obvious.
