Investors’ Relief (IR) provides Capital Gains Tax (CGT) relief for investments in qualifying shares of unlisted trading companies. Introduced in 2016, the main aim of Investors’ Relief is to promote investments in smaller, innovative UK businesses by providing a significantly reduced rate of CGT on qualifying gains. The relief is targeted at external investors and is subject to lifetime limits and minimum investment periods.
The rules governing Investors’ Relief have undergone significant changes in recent years. Following the Autumn Budget 2024, the lifetime limit for relief was reduced from £10 million to £1 million on all disposals. Subsequently, the Autumn Budget 2025 confirmed that, from 6th April 2026, the CGT rates for Investors’ Relief (IR) and Business Asset Disposal Relief (BADR) will increase to match the current CGT basic rate of 18%.
Investors’ Relief (IR) and Business Asset Disposal Relief (BADR) share similarities, both with a common goal to stimulate investment by offering decreased CGT for investors. However, while BADR is aimed at those actively involved in running the business, Investors’ Relief is aimed at external investors. Investors take a passive investment, providing capital injection without actively taking any role in the business’s operations.
Despite its tax advantages, Investors’ Relief is often underutilised, largely because the rules can be complex and difficult for investors to understand. Confused by Investors’ Relief?

What is Investors’ Relief?
Investors’ Relief (IR) provides Capital Gains Tax (CGT) relief for investments in qualifying shares of unlisted trading companies. Investors’ Relief was introduced as part of the Finance Act 2016 to complement the existing Business Asset Disposal Relief (BADR), formerly Entrepreneurs’ Relief (ER). Its primary aim was to encourage investment into smaller, unlisted trading companies that might not qualify for other tax-advantaged schemes such as the Enterprise Investment Scheme (EIS) or Seed Enterprise Investment Scheme (SEIS).
Investors’ Relief reduces the rate of Capital Gains Tax investors pay when they sell qualifying shares in a company. CGT is still charged on the profit or “gain” made from the disposal of the shares. However, IR-eligible investments allow a portion of that gain to be taxed at a preferential rate, lower than the standard CGT rate.
It is important to understand that anti-forestalling measures still apply to Investors’ Relief, just as they do for BADR. These rules, set by HMRC, are designed to prevent individuals from artificially locking in a lower tax rate by arranging disposals of shares before a scheduled rate increase. For instance, from the 6th April 2026, the Investors’ Relief Capital Gains Tax rate will rise from 14% to 18% for eligible investors. Simply entering into a contract before a rate change is not sufficient to secure the preferential old rate. Instead, the timing of the actual disposal dictates the IR CGT rate payable. Anti-forestalling measures also apply to lifetime limits or any future changes to allowances under the scheme.
Investors’ Relief – Key Facts (2026 Onwards)
- CGT Rate: 18%
- Lifetime limit: £1 million of gains
- Minimum holding period: 3 years
- Must be an external investor
- Shares must be newly issued and paid for in cash
How Does Investors’ Relief Work?
The principles of Investors’ Relief are relatively straightforward. An investor purchases shares in an eligible unlisted company, paying cash and holding these shares for a minimum of 3 years. When the shares are finally sold, they qualify for Investors’ Relief, which reduces the Capital Gains Tax rate payable on any gains. For higher and additional rate taxpayers, CGT is charged at 24%; however, utilising IR, this rate is reduced to 18% (from 6th April 2026).
Under the Investors’ Relief scheme, each investor is restricted by a lifetime limit of £1 million in gains. This is the maximum amount of gains an individual can receive while utilising the IR reduced CGT rate. Any amount exceeding this allowance will be subject to full CGT rates. The lifetime IR limit is separate from the £1 million limit for Business Asset Disposal Relief, meaning individuals could potentially benefit from both reliefs across different investments.
A Real-Life Example of Investors’ Relief
Sarah is an investor who subscribed for £150,000 of new ordinary shares in an unlisted tech startup in May 2023. She had no employment or directorship role in the company. In June 2026, after holding her stake for just over 3 years, she decides to sell her shares for £500,000.
- £500,000 (Sale Price) – £150,000 (Cost) = £350,000 Gain
- Assuming Sarah has used her annual CGT allowance and has no other gains or losses, the entire £350,000 gain qualifies for Investors’ relief
- As the disposal is after 6th April 2026, the effective IR rate is 18%
- CGT with IR: £350,000 x 18% = £63,000
- CGT without IR (as a higher-rate taxpayer): £350,000 x 24% = £84,000
- Savings: £84,000 – £63,000 = £21,000
This example highlights the substantial tax savings that can be made utilising the Investors’ Relief scheme, providing a significantly larger effective rate of return.
Qualifying Criteria for Investors’ Relief
To make a successful Investors’ Relief claim, individuals must adhere to HMRC’s qualifying conditions. These rules are designed to ensure that IR Tax relief is only offered on genuine, long-term investments in trading businesses. The following qualifying criteria must be met:
The Investor’s Status:
To qualify for Investors’ Relief, the investor must not be or have been a director or employee of the company at any time during the shareholding period. This includes individuals connected to the investor, defined by the HMRC internal manual as relatives, business partners or trustees. This principle is a fundamental distinction between IR and BADR.
- Exception: There is a limited exception for an investor who becomes an unremunerated director after making the investment, provided all other conditions are met
Shares Conditions:
- Type: Shares must be issued as ordinary shares.
- Subscription: The shares must be newly issued to the investor who subscribed wholly in cash.
- Holding Period: Must be held continuously for at least three years before disposal.
The Company:
- Status: The company must be an unlisted trading company throughout the investor’s ownership period. An unlisted company is one that is not traded on a recognised stock exchange, such as the London Stock Exchange. For the purpose of IR, the Alternative Investment Market (AIM) is considered unlisted.
- Purpose: The investment must be made for genuine commercial reasons and not as part of a tax avoidance arrangement.
Given the complexity of the Investor’s relief qualifying criteria, HMRC provides a dedicated help sheet to assist individuals in navigating potential pitfalls. However, it is highly recommended to seek expert tax advice when carrying out investments eligible for IR.
How Much Money Can Investors’ Relief Save in Capital Gains Tax?
Investors’ Relief can provide significant Capital Gains Tax savings for investors, as highlighted in the example above. However, the exact amount of money that can be saved is dependent upon a series of variables; these include:
- Investors’ Relief Rate
- Remaining Lifetime Limit
- Personal Tax Position
- Size of Gain

How to Claim Investors’ Relief
Investors’ Relief must be actively claimed and is not automatically applied to qualifying investments. The following process must be followed to make a successful IR claim:
- When to Claim: An investor’s relief claim is made through your Self-Assessment tax return, in the year in which the disposal occurs. You must complete the Capital Gains Tax Summary (SA108) pages.
- Time Limit: The deadline for making an IR claim is 12 months after the 31st January following the end of the tax year in which the disposal took place. For instance, a disposal made in the 2025/26 tax year has a self-assessment return deadline of 31st January 2027, and the claim must be made by the 31st January 2028.
- Documentation: You are not required to submit evidence with your tax return. However, you must keep thorough records of investments. This includes share subscription documents, proof of payment, and records of continuous ownership. HMRC may request this information to verify your claim.
The HMRC Investors’ Relief manual provides further guidance about making a successful claim. Given the risk of invalid claims, it is highly recommended to seek professional assistance from an experienced team of accountants, such as DS Burge & Co.
What is the Difference Between Investors’ Relief, BADR, EIS & SEIS?
All four of these schemes aim to encourage investment, but each offers its own benefits and targets unique scenarios. Typically, IR serves as an alternative when BADR, EIS, or SEIS are not eligible.
- Investors’ Relief: For external investors seeking passive shareholdings in unlisted companies with no minimum stake and a wider range of eligible businesses.
- BADR: For business owners and employees who have a minimum ownership of 5%.
- EIS/SEIS: Offers upfront income tax relief and full CGT exemption on investments, but has strict trading and company size restrictions. SEIS is aimed at very early stage companies, while EIS is designed for more established but still qualifying SME’s.
It is possible for an individual to benefit from both Investors’ Relief and Business Asset Disposal Relief in the same company, but typically only where different investments of shares qualify for each relief. For example, an individual may subscribe for shares as an external investor (qualifying for Investors’ Relief) and later acquire a separate shareholding as a director or employee that meets the conditions for BADR. Each relief is applied on a share by share basis, and the qualifying conditions must be met for the relevant holding. The individual woud be entitled to a £1 million lifetime limit for both IR and BADR

Conclusion
Investors’ Relief remains a powerful investment scheme to reduce capital gains tax obligations on eligible investments. Despite a reduction in lifetime limits to £1 million and a rise in capital gains tax to 18% from 6th April 2026, the scheme still provides a substantial reduction in CGT. This is particularly significant for high-rate taxpayers, offering tangible rewards for investors who realise substantial gains from their investments.
Despite the tax benefits that Investors’ Relief offers, it is often underclaimed, particularly because of the complex qualifying conditions and the complex claiming process, which require careful attention to detail. With HMRC actively reviewing claims to ensure compliance, professional guidance is not just helpful but a prudent step to secure entitlement.
