How to Claim SEIS Loss Relief for Both Connected and Unconnected Invest

Published by Mohsin Khan posted in SEIS, Tax Services on January 1, 2025


The Seed Enterprise Investment Scheme (SEIS) and the Enterprise Investment Scheme (EIS) offer significant tax reliefs, including SEIS loss relief, to mitigate investment risks. SEIS loss relief allows investors to offset losses against their taxable income, providing a valuable safety net. Here’s a detailed explanation of how SEIS/EIS loss relief functions and the conditions for claiming SEIS/EIS loss relief, applicable to both connected and unconnected investors.

Understanding SEIS Loss Relief


SEIS loss relief reduces the financial impact when an investment does not perform as expected. Investors can offset losses against their other taxable income, thereby reducing their overall tax liability. This loss relief benefits both connected and unconnected investors, though they must meet specific conditions to qualify. Additionally, understanding how SEIS/EIS loss relief interacts with other tax relief forms is crucial to maximising your investment strategy.

Conditions for Claiming SEIS/EIS Loss Relief

General Conditions:

  • Qualifying Shares
    The shares must be qualifying SEIS or EIS shares. This means they should meet the criteria set out by HMRC, ensuring they are eligible for the associated tax reliefs.
  • Investment Loss
    The investor must have sold or disposed of the shares at a loss. The loss is calculated based on the difference between the amount invested and the amount recovered.
  • Holding Period
    The shares must be held for at least three years to qualify for full relief. However, partial relief may be available if the shares are sold earlier, under certain conditions set by HMRC.

Connected Investors


Connected investors, such as company directors or major shareholders, can claim SEIS/EIS loss relief on the capital loss but not on the income tax relief. This means they can offset the loss against capital gains, helping to reduce their overall Capital Gains Tax (CGT) liability. However, the limitation on income tax relief can reduce the overall tax benefits.

Unconnected Investors


Unconnected investors who are not closely linked to the company can claim SEIS loss relief against their income tax. This provides a more substantial loss relief, making it a more attractive option for those looking to minimise their taxable income. The ability to offset losses against income tax, rather than just capital gains, enhances the effectiveness of SEIS and EIS as risk mitigation tools.

Worked Examples

Example 1: Unconnected Investor

Scenario: Jane invests £10,000 in an SEIS-eligible company. Unfortunately, the company fails, and her shares become worthless.

Claim: Jane can initially claim 50% income tax relief (£5,000). The remaining loss (£5,000) can then be offset against her taxable income.

Outcome: If Jane’s tax rate is 40%, she can reduce her tax liability by an additional £2,000, making her effective loss only £3,000. This significant reduction in her overall loss showcases the strength of SEIS/EIS loss relief for unconnected investors.

Example 2: Connected Investor

Scenario: John, who is a director with a 20% shareholding, invests £10,000 in an SEIS-eligible company that eventually fails.

Claim: John can only claim SEIS/EIS loss relief against capital gains, not income tax, due to his connection to the company.

Outcome: If John has capital gains, he can offset the £10,000 loss against these gains, reducing his overall CGT liability. Although John doesn’t benefit from income tax relief, the ability to offset the loss still provides a valuable tax-saving opportunity.

Claiming Process

  • Calculate the Loss: First, determine the amount of the loss by subtracting any initial tax relief claimed from the total investment. This step ensures that you have an accurate figure for your tax return.
  • Amend Tax Return: Include the loss in your tax return, specifying whether it offsets income or capital gains. Accurate reporting is essential to avoid any issues with HMRC.
  • Submit to HMRC: Provide evidence of the investment and the loss, and submit the claim to HMRC. Ensuring all documentation is in order will help streamline the claiming process.

Safety Nets of SEIS and EIS

Both SEIS and EIS provide robust safety nets through tax reliefs and SEIS/EIS loss relief, making high-risk investments more attractive. These schemes offer a range of benefits that can significantly enhance the attractiveness of investing in smaller, high-potential companies.

  • Income Tax Relief: 50% for SEIS and 30% for EIS, providing an immediate tax-saving benefit.
  • Capital Gains Tax Exemptions: Gains on SEIS/EIS shares held for three years are exempt from CGT, adding a long-term benefit for successful investments.
  • Loss Relief: It offsets losses against income or capital gains, reducing overall tax liability and effectively managing the risks associated with high-risk investments.
