The Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) are UK government schemes designed to help smaller higher-risk trading companies raise finance by offering a range of tax relief to investors who purchase new shares in those companies. Where a business is listed as 'EIS' or 'SEIS' on Crowdcube, this means that company has received advance assurance from HMRC that tax relief is likely to be available to qualifying investors. However, please note that if the law or the company's circumstances change after the date the advance assurance was given, the company may cease to be eligible.
Where a pitch is marked as 'EIS' or 'SEIS', a copy of the advance assurance will be attached to the pitch. Potential investors should review the advance assurance and take their own tax advice if required.
