EIS Income Tax Relief: 30% Off Your Bill for Higher Earners in 2026/27

A relief built for risk takers

The Enterprise Investment Scheme, or EIS, is one of the most generous tax breaks in the UK, but it comes with real risk. It is designed to encourage investment in small, early-stage trading companies by offering several layers of tax relief to investors who are willing to back them.

For higher and additional-rate taxpayers who have already used their pension and ISA allowances, EIS can be worth understanding. It is not for everyone, and the underlying investments can lose value or fail entirely.

The reliefs on offer

EIS bundles several tax advantages:

• 30% Income Tax relief on the amount invested, up to GBP 1m a year, or GBP 2m if at least GBP 1m is in knowledge-intensive companies.
• Tax-free growth, so any gain on qualifying shares held for the minimum period is free of Capital Gains Tax.
• Capital Gains Tax deferral, letting you defer an existing gain by reinvesting it into EIS.
• Loss relief, so if the investment fails you can set the loss against income or gains.

Worked example

Olivia is an additional-rate taxpayer. She invests GBP 20,000 in qualifying EIS shares.

• Income Tax relief at 30% of GBP 20,000 is GBP 6,000 off her Income Tax bill.
• Her net cost after the relief is GBP 14,000.
• If she holds for at least three years and the conditions are met, any growth is free of Capital Gains Tax.
• If the company fails and the shares become worthless, loss relief applies to the GBP 14,000 net loss, which an additional-rate taxpayer could set against income at 45%, recovering a further GBP 6,300.

In that worst case, her actual loss is reduced to around GBP 7,700 of a GBP 20,000 investment, because the reliefs cushion the downside.

The conditions to keep the relief

• Hold the shares for at least three years.
• The company must be a qualifying EIS company when the shares are issued.
• You cannot be connected to the company in certain ways, such as being an employee or holding more than 30%.
• The Income Tax relief cannot reduce your bill below zero.

Where EIS sits in a plan

EIS should be considered only after the mainstream allowances are used, because those carry far less risk. A typical order for a higher earner is:

• Use the GBP 60,000 pension annual allowance, which carries up to 45% relief and is far lower risk.
• Use the GBP 20,000 ISA allowance for tax-free, liquid growth.
• Only then, if appropriate, consider higher-risk reliefs like EIS for money you can afford to lose.

Quick recap

• EIS gives 30% Income Tax relief on up to GBP 1m invested a year.
• Growth can be free of Capital Gains Tax after three years.
• Loss relief and gain deferral add further cushioning.
• The companies are small, illiquid and high risk.
