An introduction to EIS and SEIS tax efficient investing

8 August 2019

Where a start-up or SME company is looking for external investment, and one or more individuals are looking for investment opportunities which can provide significant tax advantages, it is well worth considering the Enterprise Investment Scheme (“EIS”) or the Seed Enterprise Investment Scheme (“SEIS”).

Both EIS and SEIS are arrangements approved by HM Revenue & Customs, and so can offer tax advantages to the investor without using aggressive tax planning. We have set out some initial questions to help in considering if EIS or SEIS may work for you, and some initial points to note about both schemes, as follows:

What type of investment can qualify for EIS and SEIS?

An individual subscribing in cash for ordinary shares in a UK private company or an AIM listed company, but which isn’t listed on the Stock Exchange.

How long does the investor have to hold onto the shares?

Usually for at least 3 years, to get the tax advantages.

What are the tax reliefs?

They include:

  • income tax relief at 30% (EIS) or 50% (SEIS) of the amount of the investment, and
  • relief from capital gains tax on disposal of the EIS/SEIS qualifying shares.

Who can invest?

An individual:

  • who is not an employee of the company;
  • for EIS only, who is not a director - subject to a couple of exceptions for ‘unpaid’ or ‘business angel’ directors; and
  • who doesn’t have more than a 30% stake in the company, in terms of shareholding, voting rights, and certain other economic tests.

Which companies can take EIS/SEIS investment?

The company qualifying conditions include the following:

  • it must be a trading company or holding company of a trading group, which isn’t controlled by another company; and
  • which doesn‘t carry on an ‘excluded activity’ to a substantial extent (‘excluded activities’ includes among others banking and certain financial activities, property development, dealing in land, and providing insurance); and
  • see the table below on certain limits on size of the company, which differ for EIS and SEIS.

Do you need HMRC approval?

Yes, for both EIS and SEIS; the company can also apply to HMRC for advance assurance, prior to the investment, that it will satisfy the company qualifying conditions.

Once EIS or SEIS relief has been obtained, can it be withdrawn later?

There are some disqualifying trigger events set out in the legislation which can lead to a clawback or loss of the tax reliefs for the investor. These should be monitored during the qualifying period of share ownership.

We have set out a comparison by way of brief headlines on some of the key points on the tax reliefs and qualifying conditions for EIS and SEIS in the table below. If you would like further details or advice, please contact us.
