EIS Eligibility: Complete Guide to Qualifying Companies, Investors and Trades

The Enterprise Investment Scheme (EIS) offers investors 30% income tax relief, capital gains tax exemption, and loss relief on qualifying investments. But these benefits only apply if both the company and the investor meet HMRC’s eligibility criteria.

Getting eligibility wrong is costly. If a company issues EIS3 certificates to investors but later fails to qualify, those investors lose their tax relief — and the company faces reputational damage that can end future fundraising.

This guide covers every eligibility requirement in detail, so you can identify problems before they derail your raise.

Company Qualifying Conditions

For a company to issue shares under EIS, it must satisfy all of the following conditions at the time the shares are issued.

UK Permanent Establishment

The company must have a permanent establishment in the United Kingdom. This does not require incorporation in the UK — a company incorporated in another jurisdiction can qualify if it has a genuine UK establishment through which it conducts business. However, the company must not be listed on a recognised stock exchange (it must be unquoted).

Trading Age Requirement

The company must be within 7 years of its first commercial sale. For knowledge-intensive companies (see below), this extends to 12 years. The clock starts from the date of the company’s first commercial sale, not its date of incorporation.

If the company was formed but did not trade for several years, the age window begins only when it starts trading. However, if the company received previous SEIS, EIS, or VCT funding before the 7-year (or 12-year) window, the age requirement does not apply — but the total funding limits still do.

Gross Assets Test

The company’s gross assets must not exceed £15 million immediately before the share issue, and must not exceed £16 million immediately after. Gross assets means the total balance sheet value, including cash, before deducting liabilities. This test applies to the company and any subsidiaries on a group basis.

Employee Limit

The company must have fewer than 250 full-time equivalent (FTE) employees at the time the shares are issued. Part-time employees are counted pro-rata. This test also applies on a group basis.

Qualifying Trade Requirement

The company must exist wholly for the purpose of carrying on one or more qualifying trades, or be the parent company of a group where the business of the group as a whole does not consist substantially of non-qualifying activities.

“Substantially” is generally interpreted by HMRC as meaning 80% or more of the company’s activities must be qualifying.

Annual Investment Limit

The company must not receive more than £5 million in total from all venture capital schemes (EIS, SEIS, VCT, and Social Investment Tax Relief) in any 12-month period. For knowledge-intensive companies, this rises to £10 million.

Lifetime Investment Limit

The company must not have received more than £12 million in total from all venture capital schemes over its lifetime. For knowledge-intensive companies, this increases to £20 million. Any previous SEIS or VCT funding counts towards this cap.

Purpose of the Issue

The shares must be issued to raise money for a qualifying business activity. The money raised must be employed for the purposes of the qualifying trade within 2 years of the share issue (or 2 years of the company commencing trade, if later). The funds must not be used to acquire shares in or a trade from another company, except in limited circumstances.

Investor Qualifying Conditions

Not every investor can claim EIS relief. The investor must meet the following conditions.

The Connection Test (30% Rule)

An investor must not be connected to the company at any point during a period beginning 2 years before the share issue and ending 3 years after (or 3 years after the company begins trading, if later).

An investor is connected if they hold, or are entitled to acquire, more than 30% of:

• The company’s ordinary share capital
• The company’s voting rights
• The rights to the company’s assets on a winding up
• The rights to the company’s distributable profits

This 30% test includes shares and rights held by the investor’s associates — defined as relatives (spouse, civil partner, ancestors, lineal descendants), business partners, and trustees of settlements where the investor is a settlor or beneficiary.

Employee and Director Restrictions

An investor who is an employee of the company at the time of the share issue cannot claim EIS income tax relief. However, a director may qualify, provided they are not otherwise connected.

There is an important exception: an investor who becomes a paid director of the company only after the share issue can still qualify, provided they were not previously connected. This is sometimes called the “business angel” exception and is designed to allow experienced investors who take board seats to still benefit from EIS relief.

Unpaid directors who are not otherwise connected can claim EIS relief.

Minimum Holding Period

To retain income tax relief and qualify for capital gains tax exemption, the investor must hold the shares for at least 3 years from the date of issue (or 3 years from the date the company began trading, whichever is later). Disposing of shares before this date triggers a clawback of some or all of the income tax relief.

Individual Investment Limit

An individual investor can claim EIS income tax relief on investments of up to £1 million per tax year. If the investor invests in one or more knowledge-intensive companies, the limit rises to £2 million (the additional £1 million must be in KIC shares).

Excluded Trades: The Full List

EIS specifically excludes certain types of trade. If your company’s trade falls within any of these categories, it will not qualify — even if all other conditions are met.

Property-Related Activities

• Dealing in land — buying and selling land or buildings as a trade
• Property development — developing land or buildings for sale or rent
• Operating or managing hotels, guest houses, or nursing homes — unless the company provides significant additional services beyond accommodation (HMRC applies this strictly)

Financial and Professional Services

• Banking, insurance, and other financial activities — including money lending, debt factoring, and hire purchase
• Providing legal or accountancy services — the company itself must not be a law firm or accountancy practice

Asset-Backed Activities

• Leasing — including equipment leasing and vehicle leasing (but not short-term hire as part of a wider trade)
• Receiving royalties or licence fees — where this constitutes a substantial part of the trade (some royalty income as part of a broader qualifying trade may be acceptable)

Energy

• Generating or exporting electricity, heat, or other forms of energy — subsidised energy generation is excluded (this catches most solar, wind, and biomass schemes)
• Production of gas or fuel — unless part of a qualifying trade

Other Excluded Activities

• Forestry and timber production
• Farming and market gardening — though certain agricultural technology businesses may qualify if the trade is primarily technology-driven
• Shipbuilding — defined as the construction or repair of ships
• Coal and steel production — legacy exclusions from EU State Aid rules, still in force

The “Substantially” Rule for Mixed Trades

A company with a mixed trade — part qualifying, part excluded — can still qualify if its activities do not substantially consist of excluded trades. HMRC generally treats “substantially” as meaning 20% or more by reference to turnover, assets employed, and management time.

If 80% or more of your trade is qualifying, the remainder being excluded should not prevent eligibility. However, this is an area where HMRC’s assessment is subjective, and advance assurance is strongly recommended.

Knowledge-Intensive Company Criteria

Knowledge-intensive company (KIC) status unlocks significant benefits:

• Higher annual investment limit: £10 million (vs £5 million)
• Higher lifetime limit: £20 million (vs £12 million)
• Longer trading age window: 12 years (vs 7 years)
• Higher individual investor limit: £2 million (vs £1 million)

To qualify as a KIC, a company must meet one of two innovation conditions and one of two R&D spending conditions.

Innovation Conditions (meet one)

1. The company has created, is creating, or is intending to create intellectual property and, at the time of the share issue, the exploitation of that IP is expected to form the greater part of its business within 10 years.
2. The company’s business consists wholly or mainly of applied research carried out by the company, or by the company and a university or research institution together.

R&D Spending Conditions (meet one)

1. The company has spent at least 15% of its operating costs on R&D in each of the three preceding years (or in each year since incorporation, if less than three years old).
2. The company has spent at least 10% of its operating costs on R&D in each of the three preceding years AND it is credible that, within 10 years, the company will have a customer base or revenue that is significantly larger than at the time of the share issue.

HMRC does not have a fixed definition of what qualifies as R&D for these purposes but generally follows the guidelines used for R&D tax credits.

Common Eligibility Pitfalls

These are the issues that most frequently cause EIS applications to fail or be challenged.

Property Companies and Development

Property is the single most common reason companies fail EIS eligibility. Even if a company describes itself as a technology business, if its primary revenue comes from property transactions, lettings, or development, HMRC will treat it as an excluded trade. PropTech companies must demonstrate that their qualifying trade (the technology) is the primary activity, not a wrapper around property dealing.

Mixed Trades and the 80/20 Rule

Companies that combine qualifying and excluded activities often underestimate the proportion of excluded work. HMRC does not only look at revenue — it considers assets employed, staff time, and management attention. A software company that also has a significant consultancy arm providing accountancy services may fail, even if the consultancy revenue is below 20%.

Group Structures and Subsidiaries

All EIS tests — gross assets, employees, investment limits — apply on a group basis. A company that individually meets every condition may fail if its parent, subsidiaries, or fellow group companies push the aggregate figures over the limits. This is a particular risk for companies that have spun out of larger groups.

Connected Investor Traps

Founders who hold more than 30% of shares cannot claim EIS relief themselves. More subtly, an investor whose spouse or civil partner already holds shares may inadvertently breach the connection test through associate rules. Family investment rounds require careful structuring.

Using Funds for Acquisition

EIS funds must be used for qualifying business activity — broadly, the company’s own trade. Using EIS money to acquire another company’s trade or shares is generally prohibited unless the acquisition is of a qualifying trade that will be carried on by the company. This catches companies planning “buy and build” strategies.

How Advance Assurance Confirms Eligibility

Advance assurance is a process where HMRC reviews your company’s circumstances before you issue shares and confirms whether it is likely to qualify for EIS.

The advance assurance application requires:

• A detailed description of the company’s trade and business plan
• Financial information including management accounts
• Details of the company’s share structure
• Information about proposed investors (where known)
• Confirmation of how the funds will be used

HMRC typically responds within 6 to 8 weeks. If the company qualifies, HMRC issues a letter confirming likely eligibility. This letter is not legally binding, but in practice HMRC almost never reverses an advance assurance decision unless the company’s circumstances change materially.

Without advance assurance, there is a risk that HMRC challenges the company’s eligibility after shares have been issued and investors have claimed relief. This can result in tax relief being withdrawn — a situation that destroys investor trust.

Summary

EIS eligibility is not a single test — it is a matrix of conditions that must all be satisfied simultaneously by both the company and its investors. The qualifying trade rules are the most complex area, and the excluded trades list catches more companies than most founders expect.

The safest approach is to seek advance assurance from HMRC before raising investment. This gives your investors certainty that their 30% income tax relief, CGT exemption, and loss relief will be available. For knowledge-intensive companies, the benefits are even more substantial, with higher limits across every dimension.

Getting this right at the start saves months of fundraising friction. Getting it wrong can cost you the round entirely.
