Can I claim both EIS and SEIS relief on the same investment?
No — each individual investment qualifies for one scheme or the other depending on the company's eligibility and funding stage; you cannot double up reliefs on the same shares.

Tutto su EIS / SEIS Tax Relief
📋Presentazione+
EIS gives investors 30% income tax relief on qualifying investments up to £1m a year (£2m in knowledge-intensive companies); SEIS gives 50% relief on investments up to £200,000 a year in earlier-stage companies. Both schemes let you defer or fully exempt capital gains reinvested into the shares, subject to conditions, and shares held for at least three years are generally free of CGT on disposal. The reliefs combine to significantly reduce the effective net cost of the investment compared with the cash actually put in.
💡 Buone pratiche
- Both reliefs require the company to remain a qualifying trade for at least three years — relief can be clawed back if the company or your shareholding falls foul of the conditions early.
- SEIS's 50% income tax relief on top of reinvestment relief can make the government's effective 'contribution' to a SEIS investment extremely high — model the real net cost, not just the headline amount invested.
- Losses on EIS/SEIS shares (net of relief already claimed) can be set against income tax rather than only capital gains — valuable if the investment doesn't work out.
🔢 Esempio concreto
£10,000 invested under EIS by a 45% marginal-rate investor: £3,000 income tax relief reduces the effective net cost to £7,000, before any CGT deferral on reinvested gains.
