£276m was raised under SEIS in 2024 to 2025, up 14% on the year before, according to HMRC statistics published on 21 May 2026. Growth has slowed since the April 2023 expansion, and the latest two years of figures are provisional.
On a £10,000 stake, SEIS relief cuts the money at risk to £5,000 and EIS relief to £7,000 before loss relief. If the company fails, an additional-rate taxpayer loses £2,750 net under SEIS and £3,850 under EIS: the reliefs change the size of the bet, not the odds.
