How to claim EIS tax relief

The generous tax reliefs offered by the Enterprise Investment Scheme (EIS) – including the opportunity to claim back up to 30% of the value of your investment – often offset the higher risks associated with investing into unlisted, early-stage businesses, reducing the total exposure while maximising potential upside.  

Growth Capital Ventures’ (GCV) private investor network, G-Ventures, brings a selection of high-quality, EIS-eligible investment opportunities together in one place. 

This gives investors the opportunity to invest into high-growth startups – with a focus on tech startups, which are more important than ever and will play a key role in the UK’s post-COVID recovery – while minimising risk and potentially maximising returns with the EIS.

Below is a step-by-step guide to claiming tax relief after investing into an EIS-eligible business. 

Important note: The following is not tax advice. Tax rules change and benefits depend on circumstances. You can find HMRC’s full guidance on the subject here, or speak to an accountant if in doubt.

What you need to claim EIS tax reliefs

After you have invested into an EIS-eligible business, you will receive a share certificate and an EIS3 certificate. 

Your share certificate confirms your investment into the company, proving you are a shareholder. You will usually receive this before your EIS3 certificate. 

Your EIS3 certificate contains information you will need in order to claim your tax reliefs, including:

  • The name of the company you have invested in
  • The amount you have invested and on which you can claim tax relief
  • The date the shares were issued
  • The Unique Investment Reference (UIR) number
  • The name and reference of the relevant HMRC office

Claiming EIS tax relief on your paper tax return

If you submit a paper tax return, you will need to complete the additional information (SA101) sheet. 

In box two, entitled ‘subscriptions for shares under the Enterprise Investment Scheme – the amount on which relief is claimed’, of the ‘other tax reliefs’ section on page Ai 2, you will need to enter the total amount you invested into EIS-eligible companies for which you will claim tax relief.

The maximum amount on which relief can be claimed is £2 million, but any amount over £1 million must be for shares issued by one or more knowledge-intensive companies. 

In box 19, entitled ‘any other information’, on page TR7, enter the details from your EIS3 certificate(s) – company names, the amounts for which you’re claiming relief, the share issue date, the UIR and the HMRC office issuing your EIS3 certificate. 

You are not usually required to submit your EIS3 certificate for the investments on which you are claiming tax relief to HMRC, however they may ask to see them, so keep them safe.

Claiming EIS tax relief on your online self-assessment form

When completing your online self-assessment form, you will need to answer yes to the question on ‘other tax reliefs’ in section 3, ‘tailor your return’.

Under ‘other tax reliefs and deductions’ in section 4, ‘fill in your return’, you will need to add the total amount of all your EIS investments on which you wish to claim tax relief and can provide details of each of your EIS investments.

Alternative methods of claiming EIS tax relief

If you do not usually complete a tax return – for example, because you are employed under PAYE – there is an alternative method of claiming EIS tax relief. 

You will need to complete pages 3 and 4 of your EIS3 certificate and send them to your HMRC tax office. 

You should also use this method if you want to claim the tax relief against a previous year, or if you want to claim deferral relief as well as income tax relief.
