EIS and SEIS can offer powerful tax relief opportunities for investors and early-stage companies, but the rules are detailed, strict, and easy to get wrong. For founders, these schemes can make a business more attractive to potential investors. For investors, they can provide valuable income tax relief, capital gains tax advantages, and loss relief where the investment qualifies.
However, these benefits are only available when the company, investor, share issue, and use of funds all meet HMRC’s conditions. A small mistake in structure, timing, documentation, or investor connection can result in relief being delayed, restricted, or withdrawn entirely.
At ASWATAX, we provide specialist EIS and SEIS tax advice for entrepreneurs, business owners, investors, and professional advisers. Whether you are seeking advance assurance, preparing an investment round, reviewing investor eligibility, or claiming relief, our role is to give you clear, practical advice that protects the tax position from the outset. We also advise on the interaction between EIS and SEIS and other share schemes such as EMI, which is increasingly relevant for growing companies running both investor and employee equity programmes simultaneously.
What Are EIS and SEIS?
EIS and SEIS are UK government-backed venture capital schemes designed to encourage investment into smaller, higher-risk trading companies. They work by giving qualifying individual investors access to tax reliefs when they subscribe for new shares in eligible businesses.
For companies, the schemes can support fundraising by making investment more tax-efficient for investors. For investors, they can help reduce income tax liabilities, defer or reduce capital gains tax exposure, and provide some protection if the investment fails.
Enterprise Investment Scheme
The Enterprise Investment Scheme, or EIS, is generally aimed at growing companies looking to raise external funding. Investors can currently receive 30% income tax relief on qualifying investments up to £1 million per tax year, or up to £2 million where the amount above £1 million is invested in qualifying knowledge-intensive companies.
EIS can also provide capital gains tax deferral relief, capital gains tax exemption on disposal where qualifying conditions are met, and loss relief if the investment is disposed of at a loss. To preserve the relief, the shares usually need to be held for at least three years and the company must continue to meet the relevant conditions. Where a company qualifies as a Knowledge-Intensive Company, the investment limit increases to £2 million per tax year and certain conditions are modified. The KIC rules cover innovation criteria, the proportion of skilled employees and the nature of the research or intellectual property involved, and they are increasingly relevant for technology and life sciences companies raising EIS investment.
Seed Enterprise Investment Scheme
The Seed Enterprise Investment Scheme, or SEIS, is aimed at smaller, earlier-stage companies that are starting to trade. Investors can currently receive 50%
income tax relief on qualifying investments up to £200,000 per tax year.
SEIS can also offer capital gains tax reinvestment relief, capital gains tax exemption on disposal, and loss relief where qualifying conditions are met. As with EIS, the rules are strict, and relief can be withdrawn if the company or investor fails to meet the requirements during the relevant period.
Why You Need Specialist EIS & SEIS Tax Advice
EIS and SEIS can be extremely valuable, but they are not simple tick-box reliefs. They involve detailed conditions covering the company, investor, shares, fundraising purpose, use of money, business activities, and ongoing compliance.
Understanding Investor Tax Reliefs
EIS and SEIS reliefs can interact with income tax, capital gains tax, and loss relief. Investors need to understand what relief they may qualify for, when it can be claimed, whether carry-back is available, and what could cause relief to be withdrawn. Professional advice ensures investors do not overstate claims, miss opportunities, or rely on reliefs that may not be available.
Securing Advance Assurance
Advance assurance allows a company to ask HMRC whether a proposed share issue is likely to meet certain EIS or SEIS conditions. HMRC states that advance assurance can be used to show potential investors that an investment may qualify, although it is not a general endorsement of the investment or its performance.
For many fundraisers, advance assurance is a key part of giving investors confidence before money is committed. The application needs to be properly prepared, supported by accurate documentation, and aligned with the company’s actual fundraising plans.
Reviewing Company Eligibility
Company eligibility is one of the most technical areas of EIS and SEIS planning. For EIS, the company must generally meet conditions around trading status, UK permanent establishment, independence, gross assets, employee numbers, age of trade, qualifying business activity, and use of funds. HMRC’s current EIS guidance confirms that most companies must have fewer than 250 full-time equivalent employees and gross assets not exceeding £30 million before the share issue and £35 million immediately afterwards.
For SEIS, HMRC guidance states that a company can receive a maximum of £250,000 through the scheme, with conditions including gross assets not over £350,000 and fewer than 25 full-time equivalent employees when the shares are issued. One of the most contested aspects of company eligibility is HMRC’s risk to capital condition. HMRC will not give advance assurance, and may withdraw relief, where it considers the investment was structured primarily to generate tax relief rather than to expose the investor to genuine commercial risk in pursuit of long-term growth. Arrangements that provide investors with downside protection, guaranteed exits or rights that shield them from genuine loss risk are particular areas of concern. HMRC’s approach to this condition has tightened materially in recent years and it should be reviewed carefully before any investment round.
Structuring Shares Correctly
The shares issued under EIS or SEIS must meet specific requirements. They must be paid up in full, issued in cash, and generally must be full-risk ordinary shares. Arrangements that protect the investor from risk, guarantee an exit, or structure the investment mainly for tax avoidance can prevent relief from applying.
Getting share rights, articles, investor documentation, and fundraising materials right from the beginning is essential. Where a company has also granted EMI options to employees, the interaction between the EIS shareholder base and the option pool requires careful attention. A company must continue to be a qualifying company for EMI purposes if it has granted options, and certain changes to the share structure or investor arrangements can affect this. Founders running an EIS or SEIS round alongside an employee share scheme should take coordinated advice on both.
Managing HMRC Compliance
EIS and SEIS do not end once the investment is made. Companies must submit the relevant compliance statement to HMRC before investors can claim relief. For EIS, this is form EIS1, and for SEIS, this is form SEIS1. HMRC then issues compliance certificates for investors where it agrees the conditions have been met.
The company must continue to follow the scheme rules for at least three years after the investment, otherwise investor relief may be withdrawn.

How Our EIS & SEIS Tax Advice Works
We understand that EIS and SEIS advice needs to be both technically accurate and commercially practical. Founders need to raise money efficiently, investors need confidence, and professional advisers need clear answers that can be relied on.
Initial Assessment and Strategy Review
We start by understanding the company, its trade, funding plans, shareholder structure, and investor profile. This allows us to identify whether EIS, SEIS, or a combination of both may be suitable.
At this stage, we highlight any obvious risks, such as excluded activities, connected investors, share rights, prior funding, group structures, or issues with the proposed use of money.
Structuring the Fundraise
Once the initial position is clear, we help structure the fundraising process in a way that supports EIS or SEIS eligibility. This includes considering the order of investment rounds, share classes, investor documentation, and commercial terms.
The goal is to avoid common mistakes before they happen, rather than trying to repair the position later.
Preparing Advance Assurance
Where advance assurance is required, we prepare a clear and detailed application for HMRC. This includes reviewing the company’s business plan, financial forecasts, investor information, proposed share issue, and supporting documents.
A strong application gives HMRC the information it needs while presenting the company’s position clearly and accurately.
Supporting the Investment Process
Once investment proceeds, we help ensure the practical steps align with the tax requirements. This includes reviewing share issue timing, payment procedures, investor paperwork, and the use of funds.
This stage is particularly important because EIS and SEIS relief can be affected by the order in which actions are taken.
Post-Investment Compliance
After shares are issued, we support the compliance statement process so investors can claim their relief. We also advise on ongoing compliance to ensure the company does not take steps that could trigger relief withdrawal during the qualifying period.
This gives both founders and investors greater confidence that the relief has been properly managed from start to finish.
Speak to an EIS & SEIS Tax Specialist
EIS and SEIS can create valuable opportunities for founders and investors, but only when the rules are understood and managed carefully. The reliefs are generous because the conditions are strict, and HMRC expects companies and investors to follow the rules properly.
