For women founders considering SEIS and EIS, two tax schemes are almost uniquely British and unusually generous. They are also chronically underused by the very women who could benefit most. The Seed Enterprise Investment Scheme and Enterprise Investment Scheme offer investors income tax relief of 50% and 30% respectively. That makes them among the most powerful early-stage finance levers anywhere in Europe. A woman building a high-growth company from a kitchen table in Bristol, a co-working desk in Glasgow, or a lab in Cambridge should see that as a game changer. The reality is more complicated. Because HMRC does not publish SEIS and EIS data by founder gender, no one knows the exact share women-led startups receive. They almost certainly take only a small slice of the capital raised through these schemes. The same pattern holds in mainstream venture capital. The schemes themselves are unlikely to cause the gap; it reflects what happens before a founder ever reaches an application form.
This article is not a step-by-step checklist. It offers a data-driven look at how SEIS and EIS actually work for women founders and who is raising what. It also asks why the difference between an investable company and a merely eligible one often comes down to networks, narrative, and advance planning. We have drawn on HMRC statistics, Beauhurst deal data, and British Business Bank research. We have also used guidance from the UK Business Angels Association and specialist networks such as Investing Women. The picture that emerges is clear: SEIS and EIS are necessary but not sufficient. Knowing the rules is the easy part. Winning the investment is the editorial test.
What the Schemes Actually Offer
Before analysing who uses them, it is worth setting out what SEIS and EIS do. Both are HMRC-administered tax reliefs that encourage investment in early-stage, unquoted trading companies. They reduce an investor’s income tax bill, offer capital gains exemptions on disposal, and provide loss relief if the company fails. For startups, that means a £50,000 cheque from an angel can cost the investor as little as £25,000 once they apply SEIS relief. For founders, it means access to capital from people who might otherwise keep their money in property or equities.
The rules are precise. A company must be UK-based, unquoted, and carrying on a qualifying trade. It cannot be controlled by another company, and it must pass anti-avoidance tests. The thresholds differ sharply between SEIS and EIS, and many founders stumble because they assume the schemes are interchangeable.
| Feature | SEIS | EIS |
|---|---|---|
| Maximum company raise | £250,000 | £12 million (£20m for knowledge-intensive companies) |
| Investor income tax relief | 50% | 30% |
| Maximum annual investor investment | £200,000 | £2 million (£1m for non-knowledge-intensive) |
| Company age limit | Trading for less than 3 years | Trading for less than 7 years (10 for KICs) |
| Gross assets limit | £350,000 before issue | £15 million before issue |
| Employee limit | Fewer than 25 full-time equivalent employees | Fewer than 250 full-time equivalent employees |
| Qualifying trade restriction | Yes, including most finance, property, and professional services | Yes, similar exclusions |
| HMRC advance assurance | Recommended | Recommended |

The table reveals a deliberate staircase. SEIS is for the very earliest stage: up to £250,000, often the first external round, usually from friends, family, and angels. EIS is the bridge to larger equity rounds. It allows companies to raise up to £12 million, or £20 million for knowledge-intensive companies, while still offering attractive tax relief. A founder who successfully completes an SEIS round and then an EIS round can bring in more than £12 million of tax-advantaged equity. That is before she ever touches conventional venture capital. The opportunity is substantial. The question is who gets to use it.
The Data: Who Is Actually Raising SEIS and EIS?
The most recent HMRC venture capital schemes statistics were published in September 2024 and cover the 2023-24 tax year. They show that UK companies raised around £2.4 billion through SEIS, EIS, and Venture Capital Trusts combined. EIS accounted for the largest share, at around £1.6 billion raised by over 3,000 companies. SEIS raised approximately £220 million for more than 2,000 companies. These are not marginal schemes. They are a major artery of UK early-stage finance.
Yet HMRC does not publish SEIS and EIS data split by founder gender. That alone is a problem. Without gender-disaggregated statistics, it is impossible to know exactly how much of this capital flows to women-led businesses. What we can do is triangulate. Beauhurst, the UK’s most widely used source of high-growth company intelligence, reported in its 2025 Deal report that all-female founder teams raised just 1.6% of UK venture and growth equity by value in 2024. That is down from 2.2% in 2023. Mixed-gender teams raised around 12%. All-male teams accounted for the remainder. If SEIS and EIS corrected the gender imbalance in early-stage funding, women-led companies would be overrepresented at the seed stage. There is no evidence they are.
The British Business Bank’s Small Business Finance Markets 2024 report tells a similar story. Women-led businesses are less likely to apply for external finance and more likely to be discouraged from applying. They also receive smaller amounts when they do. The Bank’s 2024 research consistently finds that around one-third of women-led businesses report finance as a barrier to growth. The share is smaller among male-led businesses. The gap is not only about discrimination in pitch rooms. It is also about who knows the schemes exist and who has an accountant that suggests advance assurance. It is about whose network includes angels comfortable writing SEIS-compliant cheques.
There is some brighter news at the margins. Specialist networks have reported increased SEIS activity among women-led companies. These include Investing Women, the UK Business Angels Association’s women-focused initiatives, and other women-focused angel syndicates. But scale remains elusive. Until HMRC begins publishing gender-disaggregated SEIS and EIS statistics, the policy conversation will remain speculative. We would argue it should start doing so immediately.
Why Female Founders Are Underrepresented
The structural barriers are well documented but worth restating because they directly affect SEIS and EIS uptake. First, women are underrepresented in angel and venture capital networks. The UK Business Angels Association (UKBAA, 2024) has repeatedly found that women make up fewer than one in seven UK angel investors. Research on investor homophily suggests that investors are more likely to back founders who resemble them. This may narrow the funding funnel at the top for women founders before any tax relief is even discussed.
Second, women are more likely to be first-time founders without prior exit experience. A male founder who has sold a business before can call previous investors, lawyers, and accountants and assemble an SEIS round in weeks. A first-time female founder often starts from zero, learning about Companies House filings, shareholders’ agreements, and advance assurance at the same time. The administrative burden of qualifying for SEIS or EIS is manageable, but only if you know what to ask. For many women, the discovery process begins after a potential investor has already lost interest.
Third, sector bias matters. SEIS and EIS exclude several trades, including most property development, financial services, and professional services. Women-led businesses disproportionately cluster in sectors such as retail, consumer services, health, education, and creative industries. While many of these qualify, others sit in grey areas. A femtech company, a sustainable fashion brand, or a childcare platform may qualify easily. A consultancy, a lettings business, or a finance broker will not. Female founders need clearer, earlier guidance on whether their trade is excluded. Ideally they should receive it before they spend money incorporating and branding a company that can never raise SEIS or EIS.
Fourth, the childcare and caring burden continues to fall disproportionately on women. Prowess has covered this repeatedly; see our guides on free childcare for the self-employed and maternity pay for self-employed women. The point here is financial. A founder who is paying for nursery fees out of personal savings has less runway. She cannot easily spend six weeks chasing HMRC advance assurance or attending angel networking events. SEIS and EIS aim to lower the cost of capital. Yet the process of accessing them still requires time that many women do not have.
The Hidden Investability Test
Eligibility and investability are not the same thing. A company can tick every SEIS box and still fail to raise a round. Investors care about team, market, traction, defensibility, and exit potential. Tax relief is a sweetener, not a strategy. The founders who use SEIS and EIS most effectively treat them as validation tools, not shortcuts.
Advance assurance is the critical first signal. This is HMRC’s non-binding confirmation that an investment is likely to qualify for SEIS or EIS. It is not mandatory, but most angels and crowdfunding platforms will not commit without it. The application requires a detailed description of the trade, the company’s financial position, shareholder structure, and the proposed share issue. It typically takes four to eight weeks, longer if HMRC asks follow-up questions. Founders who apply early, before they have spoken to investors, signal professionalism. Those who apply late, or worse, discover they are ineligible after promising relief to investors, risk destroying credibility.
Cap table discipline is equally important. SEIS and EIS have strict rules about who can invest and how shares must be structured. For example, the shares must be ordinary shares with no preferential rights to dividends or assets on winding up. If a founder has already issued complex shares to family members or advisers, she may need to restructure them. Similarly, the company must not have raised money under EIS or VCT before an SEIS round. Getting the sequence wrong can disqualify an entire round.
Valuation discipline matters too. An inflated pre-money valuation may please the founder’s ego, but it can make the next round impossible and deter experienced angels. A company that raises £250,000 at SEIS and then struggles to justify a higher valuation for EIS will find its cap table jammed. Female founders should be especially careful, because on average they raise smaller rounds and from less experienced investors. The tax relief is attractive, but it does not remove the need for a credible path to future valuation growth.
For practical guidance on building the investor narrative, see our pitch deck guide for female founders. It covers how to frame traction, market size, and team credibility. The pitch deck and the SEIS application are two sides of the same coin. Both must prove the company is a genuine early-stage venture, not a lifestyle business dressed up as a startup.
The Contrarian Angle: When Tax Relief Distorts More Than It Helps
It is worth stating plainly: SEIS and EIS are not always good for founders. They are also not a substitute for product-market fit. The schemes can create perverse incentives that hurt women-led businesses in particular.
The first distortion is the size cap. SEIS has a £250,000 limit. A founder with strong early traction may keep her raise artificially small to stay within SEIS. That means raising less than the business actually needs. That leaves her undercapitalised and back in the market sooner than planned, often in a weaker negotiating position. EIS is more generous, but the £12 million cap and the seven-year trading limit can pressure founders. They may front-load fundraising or delay revenue-generating activities to stay eligible.
The second distortion is investor quality. SEIS and EIS reduce the net cost of an investment dramatically. They therefore attract investors primarily motivated by tax relief rather than by the business itself. A founder may end up with a cap table full of wealthy acquaintances. They may have no sector expertise, no follow-on capacity, and no appetite for the volatility of early-stage equity. That is not a board; it is a tax-planning exercise. Women founders, who on average raise smaller rounds and from less experienced angels, are more vulnerable to this dynamic.
The third distortion is the focus on equity over revenue. The existence of generous tax-advantaged equity can encourage founders to prioritise fundraising over sales. For businesses that could bootstrap, finance themselves through grants, or support themselves through revenue, an SEIS round may be unnecessary dilution. Founders should ask why they are raising. Is it because the business needs capital, or because the tax relief makes capital look cheap? The answer is not always the former.
Finally, the schemes do not address the deeper funding gap. Even if every woman-led startup in the UK raised its full SEIS allowance, the total would be modest. It would still be a fraction of the capital flowing to male-led companies at the Series A stage and beyond. SEIS and EIS are excellent tools for the first rung of the ladder. They do not make the ladder any less steep.
Policy, Networks, and What Would Move the Needle
Several initiatives aim to close the gap. Launched in 2024, the Invest in Women Taskforce is co-chaired by entrepreneur Debbie Wosskow and venture capitalist Anne Glover (UK Government, 2024). It has a target of unlocking £10 billion of institutional and private investment for female entrepreneurs by 2030. The British Business Bank has committed to improving diversity data and deploying more capital through funds that back women-led businesses. Networks such as Investing Women, the UKBAA’s women angel programmes, and the Founders Forum are creating introductions. HMRC forms alone cannot produce these.
But structural change requires more than goodwill. HMRC should publish gender-disaggregated SEIS and EIS statistics. If the Department for Business and Trade can report on the gender composition of the business population, HMRC can do the same for tax-advantaged investment. Without that data, policymakers are flying blind and female founders cannot hold institutions to account.
Accountants, accelerators, and universities should also do more. Too many founders only discover SEIS and EIS after they have incorporated, issued shares, or started trading. By then, some relief may already be lost. Free or subsidised pre-startup advice, targeted at women and underrepresented founders, would raise uptake without changing a single rule. The British Library’s Business and IP Centres, local growth hubs, and programmes such as Innovate UK’s Women in Innovation Awards are part of the answer. Our coverage of the Innovate UK grants for female founders shows how grant capital can work alongside equity. This is especially true in deep-tech and health.
Crowdfunding platforms also have a role. Platforms such as Seedrs and Crowdcube are increasingly popular routes for SEIS and EIS rounds. They can also reduce reliance on warm introductions. However, crowdfunding success depends heavily on marketing reach and existing networks, areas where women founders often start with less social capital. For more on this, see our crowdfunding guide for female founders.
What This Means for Founders Now
If you are a woman founder reading this, the practical implications are straightforward, even if the execution is not. Start with eligibility, not aspiration. Check whether your trade qualifies, whether your company structure allows SEIS or EIS, and whether your timeline fits the age limits. Apply for advance assurance before you start talking to investors seriously. Build a cap table that future investors will respect. Choose investors for their value beyond the cheque. And treat tax relief as one component of a funding strategy, not the strategy itself.
Our pages on grants for women in business and business loans for women in the UK offer other options. Compare them with SEIS and EIS. The right capital stack for a pre-revenue healthtech startup is not the same as for a growing e-commerce brand. The more founders understand the full menu, the less likely they are to accept the first term sheet that arrives.
The Bottom Line
SEIS and EIS remain two of the most founder-friendly financing mechanisms in the UK. For women founders, they offer a genuine opportunity. They can convert a good idea into a funded company without surrendering control to venture capital too early. But the schemes operate inside a wider ecosystem that still funnels most equity capital to male-led teams. Tax relief cannot compensate for unequal networks, weaker access to professional advice, or sector structures that push women towards excluded trades.
The real measure of success will not be how many founders qualify for SEIS or EIS. It will be how many women-led companies use them as a springboard to larger, sustainable, and strategically valuable businesses. That requires better data, earlier advice, investors who look more like the founders they claim to back, and stronger access to support such as grants for women in business and business loans for women in the UK. Until then, SEIS and EIS are necessary tools in a toolbox that is still missing several important instruments.
