Process

The EIS investment process: from subscription to exit

By EISInvestments.co.uk Editorial Team · Published 2026-10-25 · Last reviewed 2026-10-25

Short answer

The EIS investment process runs from due diligence and subscription, through the share issue and the company's EIS1 compliance statement, to receiving your EIS3 certificate and claiming relief. You then hold the shares for at least three years, and possibly much longer, until an exit.

Before investing

Review the company's business plan, financials, team, valuation and use of funds. Check its EIS position and understand the share rights. Firms promoting the investment must normally categorise you and check the investment is appropriate.

Subscription and share issue

You sign a subscription or application form and pay in cash. Shares must be issued and fully paid; the issue date is the date that matters for relief and for the three-year period.

Compliance: EIS1 and EIS3

The company submits form EIS1 once it has traded for four months. HMRC reviews it and, if satisfied, provides a unique investment reference. The company then issues an EIS3 to each investor.

Claiming and keeping relief

You claim relief using the EIS3. During the holding period, avoid anything that could withdraw relief, such as receiving value from the company or becoming connected with it, and tell HMRC within 60 days if a disqualifying event occurs.

Exit

Possible exits include a trade sale, a listing, a secondary sale or a share buy-back. Many companies never achieve an exit and some fail. If a company fails, you may be able to claim loss relief.

Frequently asked questions

What happens if I never receive an EIS3?+

Without an EIS3 you cannot claim relief. Contact the company; if it cannot issue one, its shares may not qualify.

Can I sell EIS shares after three years?+

You can if a buyer exists, but there is usually no market for unquoted shares, so selling may be difficult or impossible.
