All you need to know about the enterprise investment scheme

What is EIS?

The Enterprise Investment Scheme (EIS) is a UK government scheme that helps younger, higher-risk businesses raise finance by offering generous tax reliefs to investors. The scheme has been around since 1994, so is a well-established part of the UK tax landscape for investors.

Investors can claim relief on up to £1m-worth of investments in qualifying companies per person per year (this cap rises to £2m if you're investing in knowledge-intensive businesses, such as those in the life sciences sector). Even better, the scheme's carry back feature means you can apply relief on eligible investments to the preceding tax year.

Since launch, the scheme has promoted more than £10bn of private investment. The success of this scheme led to the introduction of the Seed Enterprise Investment Scheme (SEIS), which promotes investments in even earlier-stage (and therefore riskier) companies through even greater tax relief.

For a longer video explanation of the tax reliefs have a listen to BDO partner David Brooks discussing EIS.

Risk warning: Tax relief depends on an individual's circumstances and may change in the future. In addition, the availability of tax relief depends on the company invested in maintaining its qualifying status.

What benefits does EIS offer?

The benefits available through investment into EIS of EIS funds include:

  • Income Tax relief of 30% of your investment. This can be used in the year of investment or carried back one year
  • Capital Gains exemption on profits earned on shares held for a minimum of three years
  • Loss relief, should the company you’ve invested in fail, equivalent to your tax bracket multiplied by your 'at risk capital' (the total loss on the shares once Income Tax relief has been accounted for)
  • Capital Gains Tax (CGT) deferral on gains realised on the disposal of any asset which is reinvested in an eligible company or fund
  • Inheritance Tax exemption on shares held for a minimum of two years

Income Tax relief

You can claim 30% tax relief on qualifying investments up to a cap of £2m per tax year as long as at least £1m is invested in knowledge-intensive businesses, such as those in the life sciences sector.

This means if you invest £1m into qualifying opportunities, you can claim a tax reduction of £300,000 provided you have sufficient Income Tax liability to cover it.

As EIS allowances are allocated individually, a married couple could be eligible to claim tax relief of up to £2m in a single tax year (or up to £4m if investing in qualifying knowledge-intensive businesses). Income Tax relief is given at 30% of the investment, regardless of what your top rate of tax is.

The shares must be held for at least three years from the date of issue – tax relief will be given at the outset, but can be clawed back if you dispose of the shares before the three years are up.

There are complex rules around what type of company qualifies for EIS investment. While there is no way to guarantee an investment will be eligible, companies can apply to HMRC for ‘advance assurance’, which gives a provisional indication of whether or not a company may be eligible to apply for tax relief for its investors. There are also rules around investing in companies that you are connected to, so check these before investing in a company that you have links to.

Capital Gains Tax exemption

Any gains are free of Capital Gains Tax so long as you've held the shares for at least three years and have claimed at least some Income Tax relief on them. You can potentially accrue your Capital Gains Tax exemption for longer than three years as long as you continue to hold the shares.

Loss relief

Loss relief allows investors to offset a loss made on an investment against either their Capital Gains Tax bill or their Income Tax bill, depending on which better suits their individual needs. They can claim loss relief either in the tax year when they realise the loss or the following tax year. This is in addition to other EIS tax reliefs.

While the below explains how loss relief works and how you go about making a claim, we suggest you get financial advice to help you fully understand your specific circumstances.

Does my investment qualify for loss relief?

To qualify for loss relief the value of an investment, when it is sold, has to have fallen below what’s called the 'effective cost'. The effective cost is the amount invested minus whatever you previously claimed in Income Tax relief. For example, if you invested £20,000 into a qualifying investment and you then claimed upfront Income Tax relief of £6,000 (equal to 30% of the amount you invested), the effective cost of that investment would be £14,000.

Negligible value claims

It should be noted that as well as being able to claim relief for the loss on a liquidation of the company, it is also possible to make a 'negligible value' claim where the value of the investment has dropped to a negligible amount.

In the event of an investment losing value, there are attractive reliefs for Enterprise Investment Scheme (and Seed Enterprise Investment Scheme) investors. If the shares have negligible value, a claim can be made for relief even when shares are still owned. If the company has been liquidated, a decision must be made on whether to make an election to set the loss against income, and if so, whether you want to set it against your income in the tax year of the loss or the previous tax year. It is important that tax claims and elections are made before the relevant deadlines.

Claiming loss relief against Income Tax

Investors in eligible investment opportunities may be able to offset losses against their Income Tax bill for the current or previous tax year under ITA 2007, Section 131. With Income Tax rates typically being higher than Capital Gains Tax rates, most investors elect to set any loss made against their income and claim relief at up to 45%.

You can work out the amount of relief you can claim by multiplying the value of your effective loss by your marginal rate of Income Tax.

Claiming loss relief against Capital Gains Tax

Alternatively, you may want to offset your loss against your Capital Gains Tax bill for the current or future tax years. In this case, the relief can be calculated by multiplying the effective loss by the rate at which you pay Capital Gains Tax.


EIS tax relief examples

You invest £10,000. You recieve £3,000 in income tax relief
Company fails

The company in which you invested goes bust. Your shares are worth £0, but you receive loss relief

TOTAL LOSS: £3,850*

Company breaks even

You sell your shares for £10,000 after 3+ years

TOTAL GAIN: £3,000

Company doubles in value

If after 3+ years you sell your shares for £20,000, you'll owe no Capital Gains Tax on profit

TOTAL GAIN: £13,000

*You receive loss relief from the government equal to your at-risk capital (in this case the £10,000 invested - £3,000 received in Income Tax relief), multiplied by the percentage tax bracket you belong to. At a tax bracket of 45%, the loss relief would be £7,000 x 45% = £3,150. So, for £10,000 invested, your real loss is £7,000 - £3,150 = £3,850

EIS carry back

It may be possible to 'carry back' all or part of your investment to the preceding tax year as long as the limit for relief is not exceeded for that year. (The limit for the Enterprise Investment Scheme is £1m per tax year, rising to £2m provided £1m of this is invested in knowledge-intensive companies.)

This means that if you buy qualifying shares in the 2019/20 tax year, you could carry back the associated tax relief to the 2018/19 tax year, so long as your EIS cap for 2018/19 is not exceeded.

Capital Gains Tax (CGT) deferral relief

If you have capital gains greater than the annual exemption, these can be deferred by making an Enterprise Investment Scheme investment. Capital Gains Tax deferral relief freezes the gain, and the tax liability is deferred until the shares are disposed of, although a further EIS investment can be made when that happens, to defer the tax liability again. Gains deferred in this way wash out on death.

Gains arising up to three years before, and one year after, the EIS shares are issued can be deferred and there is no limit on the amount that can be invested.

While the rules state you cannot claim tax relief on investments into companies with which you are ‘connected’ by significant financial interest or employment, these rules do not apply where only deferral relief is claimed.

Our EIS Fund: Access EIS

Access EIS tracks the performance data of over 1,000 active startup investors. It then selects and co-invests with some of the best-performing “super angels” with the aim of replicating their collective success.

Access EIS aims to diversify your investment across at least 50 super-angel-backed startups to minimise risk and capture as many potential “blockbusters” as possible.

Claiming your EIS tax relief

To claim EIS tax relief, you'll need to provide HMRC with the following information:

  • The names of the companies in which you’ve invested.
  • The amounts, per company, for which you’re claiming relief.
  • The date the shares were issued (often different from the date you invested).
  • The HMRC office authorising the issue of the EIS3 certificate and its reference (as shown on the certificate).

Collating the above information in an Excel sheet will enable you to sum up the total amounts invested, which is an additional figure you will need to enter into your tax return.

For Access EIS investors, all the information you need to claim tax relief, including EIS3 certificates and a spreadsheet showing the details above, can be downloaded from your Investor Dashboard.

If you complete a self-assessment tax return

See our detailed EIS tax relief step-by-step guide which will take you through the process of making a claim.

For further details, see the HMRC Guidelines.

If you're employed under PAYE

If you are employed under PAYE or for any other reason do not normally complete a tax return, the process for claiming relief is slightly different. You will need to fill in pages 3 and 4 of the EIS certificate and send these by post to the HMRC officer dealing with your tax deductions.

EIS certificates

Here’s how the process of obtaining EIS certificates works.

  1. The company receives advance assurance from HMRC before it starts a fundraise. HMRC never guarantees that a company will certainly qualify, but an advance assurance is the closest to it you can get. You can usually download a copy of the company’s advance assurance letter from the deal page.

  2. Once the funding round is successfully completed and shares are issued, the company sends an application to HMRC (referred to as an EIS1) asking to grant investors EIS tax relief. It usually takes HMRC around three months to process this application.

  3. HMRC then sends the company blank EIS3 forms (the certificate that you receive), which the company completes and returns to you. You can attach these forms to your tax return to claim relief if you are eligible to do so.

The full process of obtaining an EIS certificate for an investment can take three to four months.

EIS rules for investors

In order to qualify for Income Tax relief, you cannot be ‘connected’ to the investee company by significant financial interest or employment. These conditions must be true for the duration of a period starting two years prior to the share issue and lasting until three years after the investment is made.

You are recognised as being connected to the company if you are a paid company employee, partner or director. The exception is if you are an unpaid director of the company, in which case you may still claim Income Tax relief.

You are also connected to the company and therefore ineligible to receive Income Tax relief if you have a 30% or greater interest in the company or any subsidiary (this includes share capital, voting rights and the rights to assets).

No partner or associate of the investor may have other interests in the company.
