Leveraging SEIS and EIS Incentives to Fuel UK Startup Growth

SEO Meta Description:
Discover how UK startups can harness SEIS and EIS for startup tax relief UK, leveraging Oriel IPO’s commission-free marketplace, curated deals and expert guidance to supercharge your fundraising and growth.


Starting up is thrilling. The challenge? Funds. You need cash to build, hire and scale. But paying tax on investor money stings. That’s where startup tax relief UK schemes—SEIS and EIS—come in. They slash your investors’ tax bill. And in turn, supercharge your fundraising appeal.

On one side, there’s the US Opportunity Zone playbook. It promises capital-gains deferral when you locate in a low-income district. It touts community impact. But it’s US-centric. Complex. And not ideal if your customers, operations and investors are here in the UK.

On the other, the UK’s Seed Enterprise Investment Scheme (SEIS) and Enterprise Investment Scheme (EIS) reward investors with generous tax breaks. You get more interest, better valuations and—critically—access to a vibrant community of angel backers.

Which path suits your startup? Let’s compare.

Understanding SEIS and EIS: Your Passport to Startup Tax Relief UK

Let’s break down the essentials.

What Is SEIS?

  • Seed Enterprise Investment Scheme.
  • Designed for very early startups.
  • Investors can claim:
  • Up to 50% income tax relief on investments up to £100,000 per tax year.
  • Capital Gains Tax (CGT) exemption on gains from SEIS shares.
  • Loss relief against income if the startup fails.

What Is EIS?

  • Enterprise Investment Scheme.
  • Targets startups at a slightly later stage or higher funding rounds.
  • Investors benefit from:
  • 30% income tax relief on investments up to £1 million per tax year (or £2 million if at least £1 million is in knowledge-intensive companies).
  • CGT deferral if you reinvest gains.
  • CGT exemption on gains from EIS shares held for at least three years.

Why These Matter for Startup Tax Relief UK

  • Attract stronger investors. Angels favour tax-efficient deals.
  • Boost valuations. You can negotiate higher pre-money figures when investors save on tax.
  • Spread risk. With loss relief, backers lose less in downside scenarios.
  • Build credibility. Listing SEIS/EIS status signals you meet HMRC’s stringent criteria.

SEIS and EIS aren’t jargon. They’re powerful tools to attract and retain investors in a competitive UK market.
