SEIS Reinvestment Relief

SEIS Reinvestment Relief

SEIS Reinvestment Relief refers to a tax relief program that is part of the Seed Enterprise Investment Scheme (SEIS) in the United Kingdom. SEIS is a government initiative aimed at promoting and supporting early-stage investments into qualifying small and early-stage companies.

Under SEIS Reinvestment Relief, individuals who have made gains from the disposal of any other chargeable assets can potentially defer those gains by reinvesting the amount into SEIS-qualifying shares. In simpler terms, if you have made a profit from selling an asset liable for Capital Gains Tax and you reinvest that profit into SEIS-qualifying shares, you may be able to postpone paying that gain’s taxes.

How Does SEIS Reinvestment Relief Work?

SEIS Reinvestment Relief works by allowing individuals who have made gains from the disposal of chargeable assets to reinvest those gains into shares of qualifying SEIS companies. Here is a step-by-step breakdown of how it typically works:

  1. Identify a Chargeable Asset: First, you need to have disposed of a chargeable asset that would trigger a Capital Gains Tax liability. Examples of chargeable assets can include stocks, property, or other investments.
  2. Find a SEIS Qualifying Company: Next, you need to identify a small, early-stage company that is eligible for the Seed Enterprise Investment Scheme (SEIS). These companies typically have fewer than 25 employees and gross assets of the equivalent of no more than £200,000.
  3. Reinvest the Gain: Within the specified time limits (one year before or three years after the disposal of the chargeable asset), you must invest the gain you made from selling the chargeable asset into shares of the SEIS qualifying company. The amount you invest will be deducted from your overall Capital Gains Tax liability.
  4. Claim Reinvestment Relief: To claim SEIS Reinvestment Relief, you need to report the reinvestment on your tax return and make sure that the SEIS company issues the necessary SEIS compliance documents.
  5. Deferral of Capital Gains Tax: By reinvesting the gain into SEIS-qualifying shares, you can defer paying Capital Gains Tax on the original gain until the disposal of the SEIS shares. This can provide temporary relief from the immediate tax liability.
  6. Disposal Relief: If you hold the SEIS shares for at least three years, any capital gains arising from the disposal of those shares will be exempt from Capital Gains Tax. This means that if the investment succeeds, you can potentially enjoy tax-free gains.
  7. Loss Relief: In the unfortunate event that the SEIS investment fails and you make a loss on the disposal of the SEIS shares, you can claim loss relief against your income or capital gains tax liability. This can help mitigate the financial impact of a failed investment.

It’s essential to note that SEIS Reinvestment Relief is subject to certain conditions and restrictions, such as the maximum investment limit, the type of qualifying shares, and compliance with HMRC guidelines. Therefore, it is recommended to consult with a tax professional or refer to HMRC guidelines for precise details and eligibility requirements.

Benefits of SEIS Reinvestment Relief

Benefits of SEIS Reinvestment Relief

SEIS Reinvestment Relief offers several significant advantages to investors, including:

  1. Deferred or Reduced Capital Gains Tax Liability:

SEIS Reinvestment Relief provides investors with the opportunity to defer or reduce their Capital Gains Tax (CGT) liability by reinvesting a portion of their capital gains into qualifying SEIS shares. This can be particularly beneficial for investors in higher tax brackets who would otherwise face a higher CGT charge.

  1. Maximized SEIS Income Tax Relief:

SEIS Reinvestment Relief allows investors to maximize their SEIS Income Tax Relief by enabling them to reinvest their capital gains into qualifying SEIS shares. This can effectively double the tax relief received, providing a substantial financial boost to investors.

  1. Support for Early-Stage Companies:

Investors play a crucial role in supporting the development and growth of early-stage companies by investing in qualifying SEIS shares. In order to expand and innovate, these companies often face challenges securing funding, which SEIS Reinvestment Relief can provide them with.

  1. Diversification of Investment Portfolio:

SEIS investments offer investors the opportunity to diversify their investment portfolios by adding exposure to high-growth potential early-stage companies. This can help to reduce overall portfolio risk while potentially enhancing long-term returns.

  1. Potential for Significant Returns:

Early-stage companies have the potential to achieve significant growth and generate substantial returns for investors. SEIS Reinvestment Relief can unlock access to these opportunities, providing investors with a chance to participate in the success of promising young businesses.

In addition to these primary benefits, SEIS Reinvestment Relief also offers several ancillary advantages, such as:

  • Increased liquidity for existing SEIS investments
  • Enhanced inheritance tax planning opportunities
  • Potential mitigation of losses from other SEIS investments

With SEIS Reinvestment Relief, investors can maximize their tax position while supporting innovative early-stage companies at the same time.

Eligibility for SEIS Reinvestment Relief

Eligibility for SEIS Reinvestment Relief

To be eligible for SEIS Reinvestment Relief, investors must meet specific criteria set by the UK government. These requirements ensure that the relief is directed towards individuals who are actively supporting early-stage companies and contributing to economic growth.

Individual Investor Eligibility

  • Must be a UK resident: The investor must be a resident of the UK for tax purposes.
  • Must have made a chargeable capital gain: The investor must have made a chargeable capital gain from the disposal of an asset, such as a property, shares, or other investments.
  • Must reinvest capital gain within three years: The capital gain must be reinvested into qualifying SEIS shares within three years of the gain arising.
  • Must claim SEIS Income Tax Relief: Investors must have claimed SEIS Income Tax Relief on the SEIS share investment.

SEIS Share Eligibility

  • Must be issued by a SEIS-approved company: The SEIS shares must be issued by a company that has been approved for SEIS by HMRC (Her Majesty’s Revenue and Customs).
  • Must be issued within three years of gain: The SEIS shares must be issued to the investor within three years of the chargeable capital gain arising.
  • Must be held for at least three years: The SEIS shares must be held for at least three years from the date of issue.

Additional Eligibility Considerations

  • Investment limits: There are limits on the amount of money that can be invested in SEIS shares each year. In the 2023-2024 tax year, the maximum investment is £200,000.
  • Risk of loss: SEIS investments are high-risk investments, and there is a significant risk of losing money. Investors should carefully consider their financial situation and risk tolerance before investing in SEIS shares.

By meeting the eligibility criteria and understanding the associated risks, investors can make informed decisions about utilizing SEIS Reinvestment Relief to optimize their tax position and support early-stage companies.

Understanding the Reinvestment Window

The reinvestment window plays a vital role in SEIS reinvestment relief and requires thorough comprehension from investors. It denotes the timeframe in which one can reinvest their profit into another SEIS-qualifying business and potentially reap tax advantages.

The window for identifying suitable replacement investments and making new investments using gains starts one year before the disposal of shares in the original SEIS investment and lasts for up to three years afterwards.

Timing is crucial when utilizing reinvestment relief. Not investing within the designated window may cause you to miss out on tax savings opportunities.

Furthermore, during this period, it is prudent for investors to thoroughly evaluate their choices and assess any potential investment opportunities that align with SEIS eligibility requirements. Conducting comprehensive research on potential enterprises and seeking guidance from experts can aid in making well-informed decisions regarding reinvesting funds.

It is crucial to fully grasp and utilize the reinvestment window in order to make the most of tax benefits with SEIS reinvestment relief. By utilizing this opportunity within the designated timeframe, investors have the potential to decrease their overall tax burden while simultaneously backing pioneering startups.

Calculating the Reinvestment Amount

Calculating the Reinvestment Amount

The amount of SEIS Reinvestment Relief that can be claimed is up to 50% of the chargeable capital gain, provided that the investment in qualifying SEIS shares is at least equal to the amount of the capital gain. If the investment is less than the capital gain, the relief is proportionately reduced.

Here’s the formula for calculating the SEIS Reinvestment Relief amount:

SEIS Reinvestment Relief = 50% * Chargeable Capital Gain * (Reinvestment Amount / Capital Gain)


  • Chargeable Capital Gain is the amount of capital gain that is subject to Capital Gains Tax (CGT)
  • Reinvestment Amount is the amount of capital gain that has been reinvested into qualifying SEIS shares

For example, if an investor makes a chargeable capital gain of £100,000 and reinvests £60,000 of that gain into qualifying SEIS shares, their SEIS Reinvestment Relief would be calculated as follows:

SEIS Reinvestment Relief = 50% * £100,000 * (£60,000 / £100,000) = £30,000

This means that the investor would be able to defer or reduce their CGT liability by £30,000.

It is important to note that investors should always consult with a tax advisor to ensure that they are claiming SEIS Reinvestment Relief correctly. The eligibility criteria and calculations can be complex, and a qualified tax advisor can provide guidance to maximize the benefits of this valuable tax incentive.

SEIS Reinvestment Relief Withdrawal

SEIS Reinvestment Relief withdrawal refers to the potential loss of the tax relief benefits associated with the Seed Enterprise Investment Scheme (SEIS) if certain conditions are not met. Here are some scenarios where withdrawal of SEIS Reinvestment Relief may occur:

  1. Non-Compliance with SEIS Requirements: If the shares in which the gain was reinvested do not meet the requirements of the SEIS scheme, such as being newly issued ordinary shares, being fully paid up, or not being subscribed for cash, the SEIS Reinvestment Relief may be withdrawn.
  2. Early Disposal of SEIS Shares: The SEIS Reinvestment Relief is contingent upon holding the SEIS shares for a minimum period of time. If the shares are disposed of before meeting this holding period requirement (usually three years), the relief may be withdrawn.
  3. Breaching Ownership and Control Restrictions: If an individual’s direct or indirect interest rates exceeds 30% in the SEIS company, either before or after the reinvestment or if certain relationships with the company violate the ownership and control restrictions, the SEIS Reinvestment Relief may be withdrawn.
  4. Failure to Comply with Reporting Requirements: To maintain the SEIS Reinvestment Relief, individuals must comply with reporting obligations set by HM Revenue and Customs (HMRC). Failure to fulfil these requirements, such as accurately reporting the reinvestment on tax returns or providing the necessary SEIS compliance documents, may result in the withdrawal of the relief.
  5. Changes in Legislation: It is also important to note that changes in legislation or tax regulations could impact the availability or eligibility for SEIS Reinvestment Relief. This means that the relief may be withdrawn or modified based on changes in the law.

To avoid the withdrawal of SEIS Reinvestment Relief, it is advisable to carefully review and comply with the specific requirements and obligations outlined by HMRC. Seeking professional advice from tax experts or consulting HMRC guidelines can help ensure compliance and maintain eligibility for the relief.

What are the SEIS Limits for 2023-24?

At present, individuals have the opportunity to invest a maximum of £100,000 in SEIS shares within a single tax year. This will result in potential income tax relief of £50,000 per tax year based on a 50% return. However, starting from 6th April 2023 (the beginning of the 2023-24 tax year), the investment limit will increase to £200,000 per tax year.
