You will normally claim EIS tax relief when you complete your tax return. You will be asked some information which is included in your EIS3 certificates. These are certificates you receive from each of the companies you invested in, typically a few months after the investment.
When can EIS loss relief be claimed?
You must make the claim within one year of the 31st January following the end of the tax year in which the loss occurred. For example, for a loss which occurred in the 2019/2020 tax year you would need to make your claim by 31st January 2022.
Who qualifies for EIS relief?
To qualify for this relief, income tax relief must have already been claimed – and not withdrawn by HMRC. Also, investors have to hold the shares for at least three years, and the company must remain EIS-qualifying for at least three years.
