Detailed information about each relief:
1) Income Tax Relief
Investing in EIS qualifying shares entitles the investor to a 30% reduction against their income tax bill. So a £100,000 investment entitles you to a £30,000 saving on your income tax bill.
- The income tax saved must relate to the year your capital is invested in shares, or you can elect to claim the relief against tax paid for the prior tax year;
- The value of relief is 30% of the amount investment no matter the effective rate of tax you pay. But you do need to have a sufficient income tax liability to cover the relief – it cannot create a repayment;
- The maximum amount on which income tax relief can be claimed is £1m of investment each tax year. If you invest into “Knowledge Intensive Companies”, up to £2m can be invested annually. Click here to learn about KICS.
- Shares must be held for a minimum of three years, if sold or given away sooner, some or all of the income tax claimed must be repaid. The same applies if a company ceases to qualify within three years. If a company fails within three years, income tax claimed should not normally need to be repaid.

2) Capital Gains Tax (CGT) free growth
When you sell shares at a profit, capital gains tax is usually payable at your marginal rate. Depending on your personal circumstances this can be either 18% or 24%. Shares that qualify for EIS relief do not attract CGT, therefore on a profitable exit, no CGT needs to be paid from the proceeds you receive. This is sometimes referred to as Disposal Relief. For very successful companies that grow to be worth many multiples of the amount invested, this can be a significant benefit.
To qualify for this relief, shares have to have been held for a minimum of 3 years prior to sale, and must have met the qualifying conditions during this time. Income tax relief must also have been claimed in respect of the investment.

3) Relief for losses
If a company fails or is exited at a loss, you can offset the loss against your tax bill. For there to be a loss, the company must have been sold for less than the “effective cost”. This is the amount you invested in that company less the income tax you claimed in respect of it. For example, if you invested £10,000 in a company and claimed income tax relief of £3,000, a loss will arise if proceeds from the sale of the company are less than £7,000 (your effective cost).
The amount of loss you can claim will be the difference between your effective cost, and the proceeds you receive.
Alternatively, a company may fall to £nil value, which can entitle a claim to be made.
You can choose whether to claim the effective loss against capital gains, or income tax. It is often beneficial to claim against income tax, and you can do so in respect of the year the loss has arisen, or the previous year.
An additional-rate taxpayer that offsets the loss on a company that falls in value to £0 could benefit from an extra [xx%] tax relief. In total, the initial 30% income tax relief plus the additional loss relief could effectively reduce a net loss per £1 invested to 38.5p.
Alternatively you can claim the loss against any capital gains tax bill for the current year, or future years on a roll forwards basis.

4) Inheritance Tax Relief
Shares in EIS qualifying companies also qualify for Business Property Relief, sometimes called Business Relief. From April 2026, everyone will have a £1 million Business Relief allowance, enabling them to leave qualifying assets (including EIS shares) worth up to £1m completely free from IHT when they die. To qualify for this relief, shares must have been held for at least 2 years when the investor passes away.
If shares (or other qualifying assets) worth more than £1 million are held at death, the excess value benefits from 50% relief from inheritance tax. As inheritance tax is typically charged at 40% of the value of the estate in excess of the nil rate bands, this can save the estate 40% (20% for assets above £1 million).
