In this guide, we break down SEIS and EIS reliefs, show you how to build a diversified startup portfolio, and reveal why partnering with Oriel IPO makes the whole process seamless. No jargon. No hidden fees. Just practical steps to keep your returns lean and your tax exposure small.
Understanding SEIS and EIS: Powerful Tax Relief Frameworks
What is SEIS?
The Seed Enterprise Investment Scheme (SEIS) offers generous incentives for small, early-stage companies. Benefits include:
- 50% Income Tax relief on investments up to £100,000 per tax year
- 100% Capital Gains Tax (CGT) exemption on gains from SEIS shares held for at least three years
- Loss relief for unused company losses, offsetting income tax bills
- Advance Assurance from HMRC to signpost eligible startups
Explore SEIS opportunities to maximise your tax-efficient investments and back promising founders.
What is EIS?
The Enterprise Investment Scheme (EIS) applies to slightly larger, scaling businesses. Key perks are:
- 30% Income Tax relief on investments up to £1 million per tax year (or £2 million in “knowledge-intensive” firms)
- CGT deferral relief, allowing you to postpone gains on other assets
- 100% CGT exemption on EIS shares after three years
- Loss relief and inheritance tax relief after two years
Learn about EIS tax relief and unlock deeper layers of tax-efficient investments.
Why High-Net-Worth Investors Embrace Startup Schemes
Putting money into SEIS/EIS isn’t just tax planning. It’s about aligning capital with innovation. Here’s why affluent investors lean in:
- Immediate tax savings boost net returns.
- CGT deferral frees up cash flow for new deals.
- Loss relief cushions downside.
- Long-term growth potential in high-impact startups.
But tackling SEIS/EIS alone can feel like bashing through red tape. That’s where Oriel IPO steps in with curated opportunities, clear compliance checks, and a commission-free subscription model that keeps your costs predictable.

Oriel IPO vs Traditional Crowdfunding Platforms
