Structuring SEIS to EIS Follow-On Rounds: The Oriel IPO Founder Checklist

The Ultimate Playbook for Your SEIS to EIS Transition

Raising early capital in the UK is a wild ride. First, you hunt down pre-seed angels with the massive tax reliefs of the Seed Enterprise Investment Scheme (SEIS). Then comes traction, your hiring needs expand, and your capital requirements outgrow that initial allowance. That brings you face-to-face with the SEIS to EIS transition, a critical pivot point where messy legal timing can easily wipe out investor reliefs or invite an HMRC audit. Getting this leap right requires knowing the legal limits, timing your share issues carefully, and keeping all your documentation clean.

Many founders stumble by trying to close mixed rounds in a single afternoon without respecting the statutory sequence. HMRC has distinct rules governing the exact point at which SEIS relief is maximised before the Enterprise Investment Scheme (EIS) kicks in. By following a clear operational roadmap and reviewing a trusted SEIS to EIS founder checklist, you protect your investors’ tax incentives, save yourself costly legal clean-ups, and position your company for scale.

Why the Jump from SEIS to EIS Catches Founders Out

Both schemes exist to stimulate equity investment into high-risk, early-stage UK companies. Yet, they are not interchangeable, and they carry very different rules.

SEIS is designed for very young companies, capped at £250,000 in total lifetime investment. It gives angel investors a remarkable 50% income tax relief alongside capital gains exemptions. EIS steps up for larger raises, offering a £5 million annual cap (or £10 million for knowledge-intensive companies) and a 30% income tax relief rate.

The friction happens when founders raise a blended round. Suppose you want to raise £400,000 from a syndicate of business angels. You plan to allocate £150,000 under SEIS to fill your remaining allowance, and issue the remaining £250,000 under EIS.

If you issue all those shares simultaneously on the same legal instrument, HMRC will likely treat all the shares as issued under EIS, or worse, invalidate the relief across the entire tranche. The legislation states that a company cannot issue EIS shares if it has not yet spent or allocated its SEIS capacity in the correct legal sequence. That single afternoon mistake can cost your early backers thousands of pounds in lost relief.

To avoid this, founders must treat these rounds as two distinct events linked by strict timing rules. Before jumping into dual-scheme negotiations, ensure you fully understand SEIS tax relief so you know what promises you can legally make to your angels.

The Core HMRC Rules for Sequencing Follow-On Rounds

To make a smooth SEIS to EIS transition, you have to master three structural requirements: the 70% spend rule, the share issue date rule, and the separate compliance filing procedure.

1. The 70% Spend Rule

Under the standard statutory requirements, you cannot issue EIS shares until you have spent at least 70% of the money raised through your previous SEIS round. HMRC enforces this condition to ensure smaller startups genuinely use their seed capital for the qualifying trade before taking on larger sums.

There is one important exception. If you are running a single combined funding round where you exhaust the rest of your £250,000 SEIS limit on Day 1 and issue EIS shares on Day 2, HMRC allows this provided the SEIS shares are legally issued first. In this specific scenario, you do not need to wait until 70% of the SEIS cash is physically spent, as long as the share issue dates are distinct.

2. The Share Issue Date Rule (No Same-Day Issues)

This rule is non-negotiable. Never issue SEIS and EIS shares on the exact same calendar day.

If you issue both classes of relief on the same day, HMRC will disallow the SEIS treatment for that tranche because you technically held EIS funds concurrently.

  • The SEIS shares must be entered into your register of members first.
  • The EIS shares must be issued at least one business day later.
  • Your board minutes, shareholder resolutions, and return of allotment (Companies House Form SH01) must clearly reflect this date difference.

If you are a founder preparing your documents, you can showcase your startup to early-stage investors who understand how structured tranches operate.

3. Advance Assurance Applications

HMRC offers Advance Assurance for both schemes. When moving between schemes, do not assume that your previous SEIS approval covers your upcoming EIS round.

EIS introduces new tests. Your gross assets cannot exceed £15 million immediately before the raise, and you cannot have more than 250 full-time equivalent employees. More importantly, your company must meet the “risk-to-capital” condition, proving that the business has genuine objectives to grow and that investor capital is truly at risk. Submit a new Advance Assurance application specifically for the EIS tranche, or a joint application detailing both tranches if you are raising a blended round.

The Oriel IPO Founder Checklist: Step-by-Step

Here is a practical, chronological checklist you can run through to navigate your SEIS to EIS transition without running into tax traps.

Step 1: Audit Your Lifetime SEIS Allowance

Check your Companies House filings and bank statements. Confirm the exact pound amount of SEIS shares previously issued. Remember, the lifetime maximum is £250,000 (increased from £150,000 in April 2023). Factor in any de minimis state aid or other qualifying subsidies that might count towards your risk-finance limits.

Step 2: Separate Your Investor Commitments

Review your term sheets. Separate your investors into two camps:
* Investors taking SEIS shares (usually smaller angel cheques or early commitments).
* Investors taking EIS shares (larger angels, funds, or family offices).

Ensure your subscription agreements explicitly specify which scheme applies to each subscriber.

Step 3: Run the Corporate Approvals

Hold a board meeting to approve the fundraising. Ensure your articles of association allow you to issue new shares without breaching pre-emption rights, or have your shareholders pass the appropriate special resolutions.

For founders who want to discover active angel networks without paying percentage-based success fees, taking time to explore EIS opportunities will clarify how sophisticated investors evaluate follow-on terms.

Step 4: Issue the SEIS Tranche First

  1. Receive the SEIS subscription funds into your company bank account.
  2. Formally allot the shares on Day X.
  3. Update your register of members on Day X.
  4. File Form SH01 at Companies House within one month of Day X.

Step 5: Issue the EIS Tranche at Least One Day Later

  1. Receive the EIS subscription funds.
  2. Formally allot the EIS shares on Day X + 1 (or later).
  3. Update your register of members with the new date.
  4. File a separate Form SH01 at Companies House reflecting the later allotment date.

Keeping these paper trails completely separate makes your compliance review with HMRC simple. If you need a single place to track deal documentation, engage potential backers, and keep communication clear, you can access the Oriel IPO Hub to organise your fundraising process.

Managing a follow-on round is also about connecting with investors who back growing teams. Founders can plan their rounds and explore UK startup EIS after SEIS using reliable structuring principles that keep both accountants and angels on side.


Checkpoint SEIS Requirement EIS Requirement
Max Lifetime Capital £250,000 £12 million (or £20 million for KIC)
Trading Age Limit Under 3 years from first commercial sale Under 7 years (10 years for KIC)

Gross Asset Limit Up to £350,000 before raise Up to £15 million before raise
Investor Income Tax Relief 50% 30%
Allotment Date Must be Day 1 Must be Day 2 or later in blended rounds

Post-Round Compliance: SEIS1 and EIS1 Submissions

Issuing the shares does not complete your obligations. Your investors cannot claim their tax reliefs until you submit the formal compliance statements to HMRC and distribute the resulting certificates.

You must file:
* Form SEIS1 for the seed tranche.
* Form EIS1 for the growth tranche.

HMRC requires that you have carried on your qualifying trade for at least four months, or spent at least 70% of the monies raised under the SEIS tranche, before you can submit your SEIS1 form.

Do not submit your EIS1 form before your SEIS1 form. Doing them out of order raises red flags with the HMRC Small Companies Enterprise Centre (SCEC). Once HMRC approves each compliance statement, they will issue unique reference numbers (URNs). You then generate SEIS3 and EIS3 certificates and distribute them to your investors, who use the claim forms on their self-assessment tax returns.

Accountants handling these submissions often partner with specialized communities. If you work in practice, you can help clients with SEIS and EIS to ensure their structural timing meets HMRC requirements.

Common Pitfalls During the SEIS to EIS Transition

Even experienced founders make avoidable mistakes during follow-on raises. Watch out for these three pitfalls:

1. The Value Received Trap

If your company repays a founder loan or buys back shares from an existing shareholder around the time of the new investment, HMRC may view this as returning value to shareholders. This can reduce or completely cancel your investors’ tax relief. Always speak to an accountant before making any non-standard payments to directors or shareholders near a funding round.

2. Preference Shares with Liquidation Preferences

SEIS and EIS rules state that all qualifying shares must be ordinary shares. They cannot carry preferential rights to the company’s assets upon a winding up, nor can they carry guaranteed dividends. If an incoming EIS investor asks for a 1x non-participating liquidation preference, agreeing to it will instantly disqualify their shares from tax relief. Stick to ordinary shares with equal voting and distribution rights.

3. Grant Funding Clashes

Did your startup receive an Innovate UK grant or an R&D subsidy? Some government grants are classed as state aid (specifically de minimis aid). These can eat into your £250,000 SEIS lifetime cap. If you received £50,000 of state aid that counts towards your risk-finance total, your remaining SEIS capacity drops to £200,000. Double-check your grant agreements before finalising the size of your seed tranche.

Connecting early with the wider funding community helps spot these issues before they hit your balance sheet. You can partner with Oriel IPO to connect with founders, angel syndicates, and advisers working through these exact problems.
