EIS Shares Explained: What Startups Need To Know Before Issuing Equity

If you’re raising investment for your startup or SME, you’ve probably heard investors ask one question early: “Will my investment qualify for EIS?”

EIS (the Enterprise Investment Scheme) can be a big deal in UK fundraising because it offers tax reliefs to eligible investors. In practice, that can make your round easier to close and help you attract investors who might otherwise sit on the fence.

But EIS isn’t something you “add on” at the end. The way you structure and issue your shares (and the way you run the company) can affect whether an investor’s shares qualify.

In this guide, we’ll break down what people mean by EIS shares, how EIS works in practice, and what you should have in place before you issue equity, so you’re protecting your business from day one.

What Are EIS Shares (And Why Do Investors Care)?

Strictly speaking, “EIS shares” aren’t a special class of shares created by company law.

Instead, the phrase is commonly used to describe newly issued shares in a company that are intended to qualify for relief under the Enterprise Investment Scheme (EIS), which is set out in UK tax legislation (including the Income Tax Act 2007 and related provisions, guidance and practice).

When the conditions are met, investors may be able to access a package of tax reliefs (subject to meeting the rules). That’s why EIS eligibility often comes up early in fundraising conversations.

What Makes Shares “EIS-Qualifying” In Simple Terms?

To be eligible for EIS relief, the investment must generally tick a number of boxes, including:

• New shares: the shares must be newly issued and fully paid up. In many cases these will be ordinary shares, and they must not carry rights that undermine the investor’s risk (for example, certain preferential or protected rights can be an issue for EIS).
• Paid in cash: EIS is generally about cash investment into the company (not swapping debt, assets, or services).
• “Risk to capital” and trading requirements: the company must be carrying on a qualifying trade and the investment must involve genuine commercial risk.
• No “guaranteed returns”: you generally can’t structure the deal so the investor is protected from downside risk (for example, through certain protected arrangements).

The key takeaway is that EIS isn’t just a tax label. It’s a set of rules that influence how your equity round should be structured, documented, and executed.

A Quick Word Of Caution

It’s completely normal to feel unsure here. EIS sits at the intersection of company law, fundraising, and tax legislation.

This article gives general legal information from a business-owner perspective. Sprintlaw can help with the legal structuring and documentation of an equity round, but we don’t provide tax advice. Eligibility can depend on the detail, so it’s worth getting tailored legal and tax advice before you issue shares or accept investor funds.

Is Your Company Eligible To Issue EIS Shares?

Not every company can issue shares that qualify for EIS, and even eligible companies can accidentally knock themselves out of qualifying if they structure the round incorrectly.

Broadly, EIS is designed to support smaller, higher-risk trading companies. That means there are limits and conditions around your company’s size, what it does, and how the money is used.

Common Eligibility Themes (The Practical View)

While the full EIS rules are detailed, these are some of the practical areas that commonly matter for startups and SMEs:

• Company type and presence: you’ll usually need to be a UK company (or meet UK permanent establishment requirements) and not be listed on a recognised stock exchange.
• Qualifying trade: some activities are excluded or restricted. If your business model is close to an excluded area, you’ll want advice early.
• Independence: your company typically can’t be controlled by another company, and there are rules about subsidiaries and group structures.
• How much you raise: there are limits on the amount of “risk finance” a company can receive over its lifetime (and per year), and EIS interacts with other schemes and grants.
• How funds are used: funds must generally be used for the growth and development of a qualifying trade within specific timeframes.

Advance Assurance: The Step Many Startups Forget

Many founders apply for Advance Assurance from HMRC before fundraising. This isn’t mandatory, but it can make fundraising smoother because it gives investors confidence that your company is likely to qualify (based on the information provided).

Advance Assurance is not a guarantee, and it doesn’t replace getting the deal structure right. But from a commercial perspective, it can reduce friction when investors do their checks.

How Do EIS Shares Work In Practice When You Raise Investment?

From your perspective as a founder or director, issuing shares intended to qualify for EIS usually sits inside a broader fundraising process:

1. You negotiate the commercial terms of the round.
2. You make sure your company and the share structure can support EIS.
3. You prepare and sign the transaction documents.
4. You issue the shares correctly (and update your statutory records and Companies House filings).
5. After the investment, you maintain ongoing compliance so investors don’t lose relief.

Let’s unpack the parts that often trip businesses up.

1) Share Type And Rights: Ordinary Shares Often Need To Be “Plain Vanilla”

EIS commonly involves investors subscribing for ordinary shares that are fully paid in cash. The shares should not include features that materially reduce the investor’s exposure to risk, and certain preferential rights can cause issues for EIS.

In fundraising, it’s common to want to give investors comfort through “preference-style” economics (like preferred returns, redemption rights, or downside protection). The challenge is that some of those features can make the shares non-qualifying for EIS.

This doesn’t mean you can’t protect investors at all. It means you need to structure protections carefully (often through governance rights rather than economic preferences) and check the EIS impact before you agree terms.

2) Timing Matters: Don’t Take Money Too Early

A classic risk is taking investor money before the paperwork and approvals are properly in place.

From a company law perspective, issuing shares usually requires proper authority and correct filings. From an EIS perspective, you also want to avoid arrangements that look like the investor is effectively “in” before the qualifying share issue.

In practical terms, that means you should plan the sequence of:

• negotiation;
• board and (if needed) shareholder approvals;
• signing;
• completion (money paid and shares issued); and
• post-completion filings.

3) Valuation And “Price Per Share” Must Be Defensible

Investors will want to know the valuation. You’ll also need to ensure the share price and mechanics make sense and are documented properly.

Valuation is commercial, but how you reflect it legally matters. If the cap table, options, convertible instruments, or earlier share issues are messy, you can end up with delays and disputes right when you’re trying to close the round.

4) Post-Investment Compliance: You’re Not “Done” After Completion

EIS relief is sensitive to what happens after the shares are issued. If the company later breaches conditions, investors could lose relief.

From a business owner’s perspective, this is why it’s important to:

• keep clean company records and statutory registers;
• document key decisions properly;
• avoid side arrangements that change the investor’s risk position; and
• stay aligned on what the company can and can’t do during the relevant period.

What Legal Documents Should You Have In Place Before Issuing EIS Shares?

When you issue equity, you’re not just raising money - you’re changing ownership and control of the company. That can be exciting, but it’s also where misunderstandings can become expensive disputes.

Having the right legal documents in place helps you:

• set expectations with investors;
• reduce the risk of founder fallouts;
• avoid messy cap table issues later; and
• support an orderly raise (including EIS-focused due diligence).

Your Company Constitution And Share Rights

Your Articles of Association are effectively your company’s rulebook. They can set out share classes, rights, transfer restrictions, and decision-making mechanics.

Before issuing shares intended to qualify for EIS, it’s worth checking whether your Articles:

• allow the share class you want to issue (and the rights attached);
• include pre-emption rights (existing shareholders’ first right to participate in new issues);
• need updating for investor governance (like director appointment rights); and
• contain anything that could accidentally create rights that are inconsistent with EIS requirements.

A Share Subscription Agreement (The Core “Investment Contract”)

A Share Subscription Agreement usually sets out:

• how much the investor is investing and at what price;
• the number and type of shares being issued;
• conditions that must be met before completion;
• warranties (promises) given by the company and/or founders; and
• completion mechanics (how and when money and shares change hands).

For EIS-focused rounds, the drafting and structure need extra care because you’re trying to meet both commercial expectations and EIS rules (for example, avoiding arrangements that look like capital protection).

A Shareholders Agreement (To Set The “Rules Of The Relationship”)

If you’re bringing on outside investors, a Shareholders Agreement is often essential. It commonly covers:

• how key decisions are made (and what requires investor consent);
• dividend policy (if any);
• how shares can be transferred (and when someone can be forced to sell);
• deadlock processes; and
• what happens on an exit.

This matters because fundraising doesn’t just bring cash - it brings new voices into how the business is run. Documenting the governance rules clearly can prevent disputes later, especially if the company grows quickly or hits a rough patch.

A Term Sheet (To Reduce Misunderstandings Early)

Many rounds start with a Term Sheet. While it’s usually not fully legally binding (except for some clauses like confidentiality and exclusivity, depending on drafting), it’s a practical tool to:

• align on valuation and structure;
• capture investor rights at a high level; and
• reduce the risk of “surprises” when the long-form documents arrive.

With EIS in the mix, the term sheet is also a good place to flag EIS intent early so everyone is negotiating within the right constraints from the start.

Founder Protections (Because Investors Aren’t The Only Risk)

If your business has multiple founders, it’s smart to tighten your internal arrangement before you bring in third-party investors.

A Founders Agreement can help clarify:

• who owns what today;
• who is responsible for what in the business;
• what happens if a founder wants to leave; and
• how big decisions will be made before (and after) investment.

Investors will often ask about founder arrangements during due diligence. If you don’t have them documented, it can slow down the round and create leverage for investors to impose terms late in the process.

Vesting (If You Want Incentives To Stay Aligned)

Many startups use vesting to keep founders and key team members committed for the long term. This is commonly documented in a Share Vesting Agreement.

Vesting is a commercial choice, but it becomes very relevant once equity is issued. It can also be important in investor negotiations because it reassures investors that the people building the business can’t simply walk away with a large chunk of equity on day one.

Common EIS Share Mistakes That Can Cause Delays (Or Kill The Round)

Most EIS problems aren’t caused by bad intentions. They’re caused by founders moving fast, using generic documents, or agreeing terms before checking the EIS impact.

Here are issues we commonly see when businesses are preparing to issue shares intended to qualify for EIS.

Agreeing “Preferred” Economics Without Checking EIS Consequences

It’s natural for investors to push for downside protection. But certain rights and arrangements can make shares non-qualifying.

If EIS is part of the deal, treat it like a design constraint from the very beginning of negotiations, not something you try to patch after signing.

Messy Cap Tables And Past Share Issues

If you’ve issued shares informally, promised equity without paperwork, or created unclear option arrangements, you may have a cap table that’s hard to diligence.

This doesn’t always prevent an EIS round, but it can:

• delay completion;
• increase legal costs; and
• reduce investor confidence.

Taking Investment Funds Before You’re Ready To Complete

Founders sometimes accept funds into a personal account, hold money “on trust”, or take money as an IOU while they “sort the paperwork later”.

That’s risky. You can end up with disputes about whether the investor is already a shareholder, what happens if the round doesn’t complete, and whether the structure still supports EIS intent.

Not Keeping Proper Company Records

Even if you do the share issue correctly, you still need to maintain your corporate records properly after completion (share allotment records, statutory registers, and filings).

If you don’t, it can create ongoing compliance headaches and make your next round harder.

Assuming EIS Is Only A “Tax Adviser Problem”

EIS is a tax scheme, but it affects deal structure, share rights, and documentation. In other words: it’s both a tax and a legal issue.

The smoother rounds happen when your legal and tax advisers are aligned early, before terms are locked in.

Key Takeaways

• EIS shares is a common way of describing newly issued shares that are intended to qualify for EIS relief, rather than a separate share class under company law.
• EIS can make fundraising easier, but only if your company and your deal structure meet the eligibility rules and avoid disqualifying arrangements.
• It’s smart to think about Advance Assurance early, because investors often expect it before committing funds.
• Before issuing EIS shares, check your Articles of Association and make sure your share rights and governance structure support both the commercial deal and EIS requirements.
• Key fundraising documents typically include a Share Subscription Agreement and a Shareholders Agreement, and many businesses also benefit from a Term Sheet to align expectations early.
• Founder arrangements and vesting should be documented early to avoid internal disputes and reduce friction during due diligence.
• Don’t DIY the legal side of an equity round - getting the documents and process right upfront can save you costly disputes and delays later.
