SEIS vs. EIS: What’s the Difference and Which One is Right for You?

Introduction

For most startups, securing the first round of investment is one of the hardest challenges. Investors are often hesitant to fund early-stage businesses due to high risk and uncertainty.

This is where the Seed Enterprise Investment Scheme (SEIS) plays a crucial role. The UK government introduced SEIS to de-risk early-stage startup investment by offering significant tax reliefs to investors.

By making startup investing more attractive, SEIS increases the likelihood of securing funding. Many angel investors, venture capital firms, and early-stage funds specifically look for SEIS-eligible startups because of the benefits it provides.

In this guide, we’ll cover:

  • Why investors hesitate to fund early-stage startups

  • How SEIS tax reliefs encourage investment

  • How SEIS-backed startups attract more investors

  • Practical steps to use SEIS in your fundraising strategy

By the end, you’ll understand why SEIS can be a game-changer for your startup’s fundraising success.

Why Early-Stage Investors Hesitate

Angel investors and early-stage funds are often reluctant to invest in new startups due to the following risks:

  • High failure rates – Many startups fail within their first few years.

  • Lack of financial history – Investors prefer businesses with proven traction.

  • Long exit timelines – Startups take years before delivering returns.

  • Uncertain market fit – Early-stage companies often pivot or fail to gain traction.

Because of these factors, investors are cautious, making it difficult for startups to secure their first backers.

SEIS directly addresses these concerns by reducing investor risk and increasing potential rewards.

How SEIS De-Risks Startup Investment

SEIS provides significant tax incentives that minimize downside risk and boost returns for investors.

SEIS Tax Benefits for Investors

  • Capital Gains Tax (CGT) Exemption – No CGT on shares held for at least 3 years.

  • Loss Relief – If the investment fails, investors can offset losses against tax, reducing downside risk.

  • Inheritance Tax (IHT) Relief – SEIS shares are exempt from IHT after 2 years.
