What is EIS? The Enterprise Investment Scheme explained

By EISInvestments.co.uk Editorial Team · Published 2026-10-04 · Last reviewed 2026-10-04

Short answer

EIS, or the Enterprise Investment Scheme, is a UK government scheme designed to encourage investment in qualifying smaller businesses by offering investors certain tax reliefs, subject to qualifying conditions.

Why the scheme exists

Young, unlisted companies often find it hard to raise money because investing in them is high risk. The Enterprise Investment Scheme was introduced in 1994 to help those companies raise equity finance by giving individual investors tax reliefs in return for accepting that risk.

The main EIS reliefs at a glance

ReliefIn summary
Income tax relief30% of the amount invested, set against your income tax liability, up to an annual investment limit.
Capital gains tax exemptionGains on qualifying EIS shares may be free of CGT if income tax relief was given and not withdrawn, and shares are held for at least three years.
CGT deferral reliefA gain on another asset can be deferred by reinvesting it in EIS shares within the permitted period.
Loss reliefIf shares are disposed of at a loss, the loss (net of income tax relief) may be set against income or gains.

Each relief has its own conditions. Figures reflect GOV.UK guidance at the date of review and can change.

Who the scheme is for

EIS reliefs are available to individuals who pay UK tax and who are not 'connected' with the company — broadly, they must not be an employee (with some exceptions) or hold more than 30% of the company. The company itself must meet conditions on its size, age, activities and how it uses the money raised.

See the detailed conditions in EIS eligibility.

What EIS does not do

EIS reduces the tax cost of an investment; it does not reduce the business risk. A company can fail regardless of its EIS status, and relief can be withdrawn if conditions are broken during the qualifying period.

How investors typically access EIS

  • Directly, by subscribing for new shares in a single company.
  • Through an EIS fund or portfolio service that invests in several companies on the investor's behalf.
  • Via an investment platform or adviser arranging the investment.
