What Are SEIS and EIS?
Before diving into comparisons, let’s define the terms in plain English.
The Seed Enterprise Investment Scheme (SEIS)
SEIS is a government-backed programme for very early stage companies. It offers:
- 50% income tax relief on investments up to £100,000 per tax year
- Share capital must not exceed £200,000
- Fewer than 25 full-time employees
- Companies must be trading for less than 2 years
- Only qualifying trades apply (exclusions include banking, insurance and property development)
SEIS is ideal for startups that need seed cash to develop a prototype or proof of concept. It carries more risk but also offers the biggest up-front relief under SEIS/EIS investment UK.
The Enterprise Investment Scheme (EIS)
EIS kicks in at a later growth phase. Key points:
- 30% income tax relief on investments up to £1,000,000 per tax year (or £2,000,000 for knowledge-intensive firms)
- Gross assets must not exceed £15 million before funding (£16 million after)
- Up to 250 employees (or 500 for knowledge-intensive companies)
- Must be trading for less than 7 years (10 years for knowledge-intensive)
- Similar trade exclusions to SEIS
- Offers CGT deferral and loss relief
EIS suits companies that have traction and need capital to scale production, marketing or export. The relief is a bit smaller, but the scale of investment grows under SEIS/EIS investment UK.
SEIS vs EIS: Key Differences
Comparing the two can feel like juggling dates and numbers. Here’s a bullet list to keep it simple:
- Stage focus: SEIS for pre-revenue or first-year firms, EIS for growth stage
- Fundraising cap: SEIS max £250,000, EIS max £5,000,000 per year (£10,000,000 for knowledge firms)
- Investor relief: SEIS 50% up to £100,000, EIS 30% up to £1,000,000
- Assets & employees: SEIS <£200,000 & <25 staff, EIS <£15m & <250 staff
- Holding period: 3 years for both to secure income tax relief
- Inheritance tax: 100% relief after 2 years under either scheme
- Risk profile: SEIS carries higher risk with higher reward, EIS is more mature with moderate relief
- Types of relief: SEIS offers capital gains tax exemption on reinvested gains, EIS offers deferral

Eligibility Criteria
To benefit from SEIS or EIS, both companies and investors must tick certain boxes. Here’s the lowdown.
Company Requirements
A company must:
- Have a permanent UK establishment
- Operate a qualifying trade, not in excluded sectors like banking or legal services
- Be independent (not a subsidiary)
- Not exceed gross assets or employee counts per scheme
- Not have previously raised more than the lifetime limit (£250,000 for SEIS; £12m for EIS)
Investor Rules
An investor must:
- Not hold more than 30% of the company’s shares (directly or via associates)
- Not be connected to the company as an employee (unpaid directors can qualify)
- Hold shares for at least 3 years to secure relief
- Invest in ordinary, non-redeemable shares with no preferential rights
- Not use funds to repay existing debts or buy property
These checks keep the schemes fair and on track for genuine business growth. Criteria for SEIS/EIS investment UK hinge on strict rules, but compliance unlocks significant value.
Tax Relief Benefits Explained
The real draw is the tax breaks. Let’s unpack each type.
Income Tax Relief
- SEIS: 50% relief on up to £100,000 per year
- EIS: 30% relief on up to £1,000,000 per year (£2,000,000 for knowledge firms)
You claim relief through your self assessment. The reduction applies in the same tax year as your investment.
Capital Gains Tax (CGT) Relief
- SEIS: 100% exemption on gains up to the amount invested, if shares held 3 years
- EIS: Defer any chargeable gains if you reinvest in EIS shares, relief earned while held
Inheritance Tax (IHT) Exemption
Shares under either scheme qualify for 100% IHT relief after a 2-year holding period. That is a powerful estate planning tool.
Loss Relief
If your EIS investment fails you can offset losses against income. It softens the blow if a business does not thrive.
These tax breaks mean that benefits of SEIS/EIS investment UK can include reduced up-front cost, protected gains and protected estates.
