Raising investment is exciting - but for many UK startups and small companies, the real unlock is being “EIS eligible”. If you can offer investors Enterprise Investment Scheme (EIS) tax relief, it can make your round far more attractive and help you close sooner.
In this guide, we walk you through how an EIS application works under UK law, who qualifies, the steps from HMRC advance assurance to issuing investor certificates, and the legal documents you’ll need. We’ll also flag common pitfalls that can accidentally disqualify your round.
If you’re planning to apply for EIS this year, getting your legal foundations right from day one will save you costly delays later.
What Is An EIS Application?
The Enterprise Investment Scheme (EIS) is a UK government scheme in Part 5 of the Income Tax Act 2007 designed to encourage investment into early-stage, high-risk companies. If your company qualifies, your investors may be eligible for generous tax reliefs (such as 30% income tax relief, potential CGT exemption on gains, and loss relief), which makes your round easier to close on fair terms.
An “EIS application” usually refers to two related HMRC processes:
- Advance Assurance: an optional, pre-investment indication from HMRC that your company and the proposed shares are likely to qualify for EIS if you proceed as outlined.
- Compliance Statement (EIS1): the post-investment submission to HMRC once you’ve issued shares and started trading/used funds, which enables HMRC to authorise EIS certificates (EIS3) for your investors.
While advance assurance isn’t legally required, most sophisticated investors will want to see it before they commit. It reduces uncertainty, aligns expectations, and demonstrates you’ve thought through the compliance details.
Are You Eligible For EIS? Company And Investment Tests
Before you apply for EIS, check the core eligibility tests. HMRC will focus on both the company and the proposed shares. In simple terms:
Company-Level Conditions
- Qualifying Trade: You must carry on a qualifying trade on a commercial basis with a view to profit. Excluded activities include (among others) financial services, property development, leasing, energy generation with feed-in tariffs, and dealing in land or commodities.
- Gross Assets: Typically not more than £15 million before the share issue and £16 million immediately after.
- Employee Count: Fewer than 250 full-time equivalent employees (or 500 for knowledge-intensive companies).
- Company Age: Generally within 7 years of first commercial sale (10 years for knowledge-intensive companies). There are exceptions for follow-on investments.
- Permanent Establishment: A UK permanent establishment is required.
Investment-Level Conditions
- Funding Limits: Up to £5 million under risk finance schemes per year, with a lifetime cap of £12 million (or £20 million for knowledge-intensive companies).
- Use Of Funds: Money must be used for growth and development of the business, and spent within two years of the share issue (or the start of trading, if later).
- Risk-To-Capital: Investors’ capital must genuinely be at risk, and the company must have growth objectives. HMRC will look for real commercial risk, not arrangements designed for tax advantage.
- No Disqualifying Arrangements: Avoid structures that reduce risk artificially (e.g. capital protection, guaranteed exits).
Share Requirements
- Full-Risk Ordinary Shares: Newly issued shares paid up in full, with no preferential rights to assets on a winding-up or to fixed returns.
- No Redemption Or Protection: Shares can’t be redeemable or carry investor protections that undermine the “risk capital” principle.
- No Linked Loans Or Pre-Arranged Buybacks: These can jeopardise relief.
Getting the share terms right is critical. If you include preference rights that look like capital protection or fixed returns, you can inadvertently disqualify the round for EIS. If you’re considering share features and pricing, it’s wise to understand how share premium works in practice and avoid any “preference” mechanics that conflict with EIS rules. In particular, be careful with concepts like preference shares, redemption rights and anti-dilution protections - they often need a bespoke approach (or to be avoided) for EIS compliance.
How To Apply For EIS: Advance Assurance To Investor Certificates
The typical journey to apply for EIS (and evidence relief for investors) runs in four stages:
1) Prepare For Advance Assurance
Advance assurance is optional, but it’s a strong signal to investors. You’ll submit a pack to HMRC including:
- Business plan and financial forecasts that demonstrate growth and risk-to-capital.
- Details of the proposed funding, spending plan and timeline.
- Company structure, cap table and any subsidiaries.
- Draft investment documents (term sheet and share subscription) that show the share rights.
- Investor details (named potential investors or a statement about your target investor profile).
Investors expect to see a clear route from term sheet to final documents. Make sure your Term Sheet reflects EIS-compatible share rights and that your final Share Subscription Agreement won’t introduce disqualifying preferences later.
2) Close The Round And Issue Shares
Once investors commit, you’ll complete legals, take funds, and issue ordinary shares. To preserve EIS eligibility:
- Issue new, fully paid-up ordinary shares (no redemption rights, no fixed return).
- Avoid linked loans or arrangements that provide capital protection.
- Ensure your use-of-funds plan aligns with growth and development.
If you want to bridge to a priced round, consider whether an Advanced Subscription Agreement fits your strategy. HMRC guidance recognises ASAs if structured carefully; however, not all convertible instruments are EIS-friendly. Be cautious with convertible notes and “SAFE” instruments - the tax treatment differs and, in many cases, a standard SAFE vs ASA analysis will show that only a tailored ASA structure tends to align with EIS expectations.
3) Submit The EIS1 Compliance Statement
After you issue shares, you can’t apply for EIS certificates straight away. You must first have started trading for at least four months or have spent at least 70% of the money raised. Then, you submit the EIS1 compliance statement to HMRC, confirming the round and eligibility.
HMRC may ask for supporting documents and can take several weeks to process. If successful, they’ll issue an EIS2 compliance certificate to your company and authorise investor certificates.
4) Give EIS3 Certificates To Investors
Once HMRC authorises, you issue EIS3 certificates to investors, enabling them to claim EIS reliefs on their tax returns. Keep accurate records and ensure each investor receives the correct certificate for their subscription.
Draft The Right Investment Documents (And Avoid Disqualifying Terms)
When you apply for EIS and close an EIS-qualifying round, your legals do a lot of heavy lifting. A few practical pointers:
- Keep Shares “Full Risk”: Avoid redemption rights, fixed or cumulative dividends, liquidation preferences that look like capital protection, or ratchets that severely reduce risk.
- Be Precise In Term Sheets: If the high-level term sheet includes preferences, investors may expect them later - which can conflict with EIS. Lock in EIS-friendly terms early.
- Use Strong, EIS-Compatible Documents: Bespoke drafting prevents accidental disqualification and reduces HMRC queries.
- Align Investor Protections Elsewhere: Some investor rights can be handled via governance rather than economics (e.g., information rights or reserved matters in a Shareholders Agreement).
Your core documents will usually include a Share Subscription Agreement, the board and shareholder resolutions to approve the issue, updated cap table filings and, often, a side letter capturing investor information rights. If you’re bridging to a priced round, weigh up whether to use an ASA now and convert later; our guide comparing a SAFE note vs ASA sets out the practical differences and risks.
If you’re considering alternative instruments like a Convertible Note, get tailored advice - the interest, redemption, and repayment features common in notes can undermine EIS eligibility.
Using The Money And Staying Compliant After You Apply For EIS
EIS doesn’t end with your application. Ongoing compliance matters to protect investor reliefs across the required holding period.
Use Of Funds And Timeline
- Spend Funds Within Two Years: Money must be used for growth and development within two years of the share issue (or of trading commencing, if later).
- Qualifying Business Activity: Ensure spending supports your qualifying trade and growth objectives described to HMRC.
Investor Holding Period
- Minimum Three Years: Investors generally must hold their shares for at least three years from the date of issue (or from when you start trading, if later) to retain relief.
- Avoid Disqualifying Events: Certain corporate actions within that window - e.g., a buyback, returning capital to investors, or moving into excluded activities - can claw back relief.
Company Actions To Approach With Caution
- Share Buybacks And Redemptions: Returning capital early or redeeming shares can be a disqualifying event if it benefits EIS shareholders within the risk period.
- Issuing Preference Shares: Introducing new preference classes with asset priority or fixed returns can put the “full-risk” profile of the EIS round under scrutiny.
- Debt Replacements: Exchanging investor equity for debt or providing guarantees can impact the risk-to-capital assessment.
Compliance doesn’t mean you can’t grow. It means planning corporate actions with the EIS clock in mind. If in doubt, speak to a legal expert before you make changes to your share capital or trade.
Common Pitfalls When You Apply For EIS (And How To Avoid Them)
A few missteps come up again and again in EIS applications. Here’s how to steer clear:
- Missing The Risk-To-Capital Story: HMRC wants to see genuine risk and a growth plan. A light business plan or generic forecasts can slow or derail advance assurance. Be specific about markets, milestones and how funds will be deployed.
- Disqualifying Share Rights: Fixed or cumulative dividends, redemption mechanics, or liquidation preferences that look like capital protection can all cause problems. Keep shares ordinary and full-risk.
- Using The Wrong Instrument: Some convertibles (and notes) won’t work for EIS. If bridging, consider an EIS-aware ASA and document it carefully.
- Late Compliance: Don’t forget the EIS1 timing - you need to have traded for at least four months or spent 70% of funds before submitting. Keep your records tight to speed up HMRC’s review.
- Ignoring Follow-On Limits: Make sure future rounds fit within your annual and lifetime risk-finance caps and company “age” rules (with knowledge-intensive exceptions where applicable).
- Not Aligning Governance Early: Where investors want oversight, use governance tools (like a Shareholders Agreement) rather than economic rights that could jeopardise EIS.
It can feel like a lot, especially when you’re juggling a live fundraise. A clean set of documents - from Term Sheet to Share Subscription Agreement - and a clear EIS narrative will make the HMRC process far smoother and give investors confidence.
Key Takeaways
- EIS can make your round significantly more attractive by offering investors tax reliefs - but only if your company, trade and shares all meet HMRC’s “full-risk” and growth criteria.
- Advance assurance isn’t mandatory, but it’s a powerful step to de-risk your raise; prepare a robust business plan, forecasts, and EIS-friendly draft documents to support your case.
- Keep share terms simple and compliant: newly issued, fully paid, ordinary shares without redemption rights or fixed returns. Use governance tools (not economic protections) for investor oversight.
- Time your compliance: submit EIS1 after trading four months or spending 70% of the funds, then issue EIS3 certificates once HMRC authorises them.
- Plan ahead for the three-year investor holding period and avoid disqualifying events (buybacks, redemptions, capital returns, or moving into excluded activities).
- Choose the right fundraising instrument for your stage - a well-drafted ASA, Term Sheet and Share Subscription Agreement tailored for EIS can keep you compliant and investor-ready.
