Understanding SEIS: The Basics
What Is SEIS?
The Seed Enterprise Investment Scheme (SEIS) is a UK government initiative. It’s built to encourage investment in micro and early-stage companies. In short: you get tax breaks. Investors get income tax relief on up to £100,000 per tax year. Founders get to showcase their pitch to seasoned angels. Everybody wins.
Key facts at a glance:
– Launched in 2012
– Targets companies under two years old
– Maximum funding per company: £150,000
– Income tax relief: 50% of investment
– Capital gains tax exemption on disposal
Why SEIS Matters for Startups
Cash is king, especially in the seed phase. SEIS isn’t just about tax perks. It’s a signal. When a savvy investor uses SEIS, it shows they believe in your idea. A strong SEIS track record can open doors to other funding rounds. And by guiding you through the maze, Oriel IPO’s platform helps you focus on product and growth—not paperwork.
SEIS Tax Benefits Unpacked
SEIS delivers four main sweeteners. Let’s break them down.
1. Income Tax Relief
Investors can claim back 50% income tax relief on investments up to £100,000 per tax year. So, if you invest £20,000, you could reduce your income tax liability by £10,000. Simple maths. Real savings.
2. Capital Gains Tax Exemption
Hold your SEIS shares for at least three years? Any profit on disposal is tax-free. No Capital Gains Tax. That means every pound of growth stays in your pocket. A serious win for patient capital.
3. Loss Relief
Startups are risky. If things go south, investors can offset losses against their income. The loss relief can cut the effective downside to just 14% of the original outlay. It’s a built-in safety net when you back early ideas.
4. Inheritance Tax Relief
After holding SEIS shares for two years, they qualify for 100% relief from Inheritance Tax. Passing on shares becomes smoother. Long-term wealth planning just got more attractive.
