Why SEIS vs EIS matters to you – your quick guide
If you’ve ever looked into early-stage investing in the UK, you’ve probably come across the Seed Enterprise Investment Scheme. It’s a government initiative designed to lure private investors into startups with tax perks. Then there’s the larger cousin, the Enterprise Investment Scheme. They both offer big breaks on income tax and capital gains tax, but they serve slightly different goals.
Picking the right scheme can feel like choosing the right map in a maze. One wrong turn and you miss out on relief or hit compliance roadblocks. That’s why understanding the Seed Enterprise Investment Scheme—and when to switch to EIS—is key. Ready to see how the Seed Enterprise Investment Scheme can transform your portfolio?

Understanding the Seed Enterprise Investment Scheme
What is SEIS?
The Seed Enterprise Investment Scheme (SEIS) launched in 2012. It rewards investors who back very young companies. You can claim:
– 50% income tax relief on investments up to £100,000 per tax year
– 50% reinvestment relief on capital gains
– Exemption from capital gains tax on eligible shares held for at least three years
It’s tailor-made for high-risk, early-stage startups. The trade-off? Strict eligibility rules and lower investment caps.
Key benefits of SEIS
Why do investors love SEIS?
– Large tax breaks: Slash your tax bill in half
– Capital growth: Profits from shares can be tax free
– Portfolio diversity: Back new ideas at the ground level
Eligibility criteria for SEIS
Before you invest, check these must-haves:
1. Company must be under two years old
2. Gross assets under £200,000
3. Fewer than 25 employees
4. Funds used for growth and innovation
If that sounds picky, it is. But it keeps the scheme targeted on the riskiest ventures.
Diving into the Enterprise Investment Scheme
What is EIS?
The Enterprise Investment Scheme (EIS) has been around since 1994. It looks at slightly more mature businesses than SEIS. You get:
– 30% income tax relief on investments up to £1 million (or £2 million if at least £1m is in knowledge-intensive companies)
– Loss relief against income or capital gains
– 100% deferral of capital gains tax when reinvesting gains
– Capital gains tax exemption on eligible shares held for three years
It’s a clear next step once a startup moves beyond seed stage.
Primary perks of EIS
Top reasons to choose EIS:
– Higher investment limits: Up to £1m per year
– Deferred gains: Reinvest gains without paying tax now
– Protected downside: Loss relief cushions failures
Who can apply?
EIS is open to companies that:
– Are trading for less than seven years
– Have assets under £15m
– Employ under 250 staff (or 500 in knowledge-intensive firms)
– Are genuinely running a qualifying trade
It’s stricter than SEIS in some ways, but it funds businesses ready to scale.

Navigating compliance and tax implications
Compliance is where many stumble. HMRC can be unforgiving if paperwork is late or criteria aren’t met. You need to:
– File SEIS1 or EIS1 forms on time
– Ensure the company issues compliance certificates (form SEIS3/EIS3)
– Keep detailed records of share certificates, board minutes, and fund allocation
It’s a lot of admin. Accountants and tax advisers often guide startups and investors through this maze. If you’re in practice, you can Help clients with SEIS and EIS with expert support and reduce the stress of compliance.
