1. Harness SEIS for Immediate Tax Relief

SEIS is the golden ticket for early-stage investors. With up to 50% income tax relief on investments up to £100,000 per tax year, it’s hard to ignore. Here’s how to make it count:

Why SEIS Matters in 2025

  • High relief rate: Slash half your investment off your tax bill.
  • Capital Gains Reinvestment: Reinvest a gain into SEIS and get CGT relief too.
  • Small-ticket access: Many founders seek £50k-£150k; you can get in at that level.

Steps to Qualify

  1. Choose a qualifying startup: fewer than 25 employees, assets under £200k.
  2. Invest before the company’s first commercial sale.
  3. Hold shares for at least three years to keep your relief.

Pro Tip

Diversify by sector — tech, green energy, health — to spread risk. Use Oriel IPO’s vetted deal flow to spot eligible SEIS opportunities quickly.

2. Maximise Gains with EIS

After you’ve soaked up SEIS relief, it’s time to move up the ladder. EIS offers 30% income tax relief on investments up to £1 million per tax year. You also get:

  • CGT exemption on disposal profits if you hold shares for three years.
  • CGT deferral on gains reinvested into EIS companies.
  • Inheritance Tax relief after just two years.

By combining SEIS and EIS, you can shape tax-efficient, layered growth. Cast your net wider without losing the cushion of relief.

3. Reinvest Gains to Slash Your CGT Bill

Let’s say you sold shares earlier this year and faced a hefty CGT charge. You can defer or avoid that tax by reinvesting gains into SEIS or EIS schemes.

How It Works

  • EIS deferral: Reinvest gains into an EIS within three years before or one year after your gain.
  • SEIS gain exemption: If you reinvest into SEIS, you may erase the CGT due on that disposal.

Action Steps

  1. Map your gains: Identify recent share sales triggering CGT.
  2. Check Oriel IPO’s marketplace daily for new SEIS/EIS deals.
  3. Allocate your gain reinvestment across one or more companies to spread your bet.

This approach keeps your capital cycling back into startups while legally lowering your tax bill.

4. Build a Blended SEIS & EIS Portfolio

A one-size-fits-all portfolio can hurt. Mix small and medium tickets to balance risk and reward:

  • Start with SEIS: high relief, early-stage risk.
  • Follow up with EIS: lower relief, more mature startups.
  • Consider sector focus: fintech, biotech, clean tech.

Oriel IPO curates startups based on growth potential and SEIS/EIS eligibility. You get quality over quantity. No guesswork.

Sample Blend

Scheme Investment Range Tax Relief Risk Level
SEIS £5k–£50k 50% High
EIS £10k–£250k 30% Medium

By using a blend you can cushion losses in one scheme with gains in another.

5. Tap into Follow-On Funding and Diversification

Once your SEIS stake matures, look for follow-on rounds via EIS. This keeps tax relief in play and signals confidence to other investors.

  • Oriel IPO’s commission-free platform makes it easy to spot follow-on rounds.
  • Educational webinars guide you through due diligence.
  • Transparent fees ensure more of your money works for startups, not middlemen.

Risk Management

  • Spread investments over at least 10 companies.
  • Avoid too many in one sector.
  • Rebalance annually: sell a matured stake and recycle proceeds.

This strategy marries diversification with layered relief.
