Understanding SEIS and EIS: A Dual Engine for Ethical Growth

What is SEIS?

SEIS is the UK government’s way of giving you upfront tax relief when you back very early-stage businesses. You can claim:
– Income tax relief of up to 50% on investments up to £100,000 per tax year
– No capital gains tax if the shares are held for at least three years
– Loss relief if your investment doesn’t work out

It’s perfect for investors who want a big slice of tax relief and don’t mind backing nascent ventures. You also help founders who might otherwise struggle to raise share capital.

What is EIS?

EIS picks up where SEIS leaves off. It targets slightly more mature SMEs and offers:
– Income tax relief of up to 30% on investments to £1 million per tax year
– Capital gains tax exemption if held for at least three years
– Carry back relief to offset prior year tax bills
– Loss relief similar to SEIS

EIS widens your options to businesses scaling up their operations, while keeping tax-efficient strategies front and centre.

Criteria for Ethical Ventures

Investing ethically isn’t just about slapping “green” on a label. It’s about rigorous due diligence. Look for ventures that:

  • Align with global sustainability goals (e.g. SDGs)
  • Demonstrate strong corporate governance and transparency
  • Measure environmental and social impact, not just profits
  • Commit to robust “polluter pays” policies and carbon reduction targets

Oriel IPO’s curated marketplace vets each opportunity against these criteria, so you only see startups that genuinely drive change.
