The Enterprise Investment Scheme Association (EISA) is the official trade body representing over 400 members—including entrepreneurs, investors, advisers, fund managers, lawyers, accountants, and wealth managers—engaged with the Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS). These government-backed schemes provide tax incentives to encourage private investment in early-stage and high-growth UK companies, offering income tax relief, capital gains tax exemptions, and loss relief. The private company is based in London, UK. EISA supports its membership through tailored categories, resources such as a knowledge hub, member directory, policy updates, accreditation courses, events, and networking opportunities. The association advocates for the schemes by engaging with government and regulators, promotes professional and ethical standards, and fosters diversity initiatives. EISA emphasizes the importance of understanding the long-term, illiquid, and higher-risk nature of EIS/SEIS investments and encourages members to seek independent advice.
