1. Company Details
- Name of company
- Corporation Tax Unique Taxpayer Reference (UTR)
- Company registration number and incorporation date

If you’re a Knowledge-Intensive Company (KIC), HMRC will ask a separate set of questions — seek advice if you’re unsure whether you qualify.

You must demonstrate that the company:
- Has long-term objectives to grow and develop its trade (refer to your uploaded business plan)
- Exposes investors to a genuine risk of losing their capital

- Any de minimis State aid or risk finance previously received
6. Capital and Purpose
- State the total capital you intend to raise.

- Ensure your figures align with your business plan and forecasts.
7. Share Details
- Indicate the class of shares to be issued.
- Confirm whether there are any preferential rights (e.g. dividend or liquidity preferences).💡 Important: Preferential rights can disqualify you – seek advice if your shares include any preferences.

✅ Uploading Supporting Information

- Business plan (including financial forecasts)
- Subscription or side agreements with investors
- Latest company accounts (or management accounts/detailed activity summary if not yet available)
- Shareholder register at the date of submission
- Memorandum and Articles of Association, with any planned amendments
- Investor materials (e.g. pitch deck, information memorandum, or prospectus)
💡 Tip: Combine documents into one clear PDF if possible, and label each file with its content (e.g. “BusinessPlan_CompanyName_2025.pdf”).
💡 Key/Practical Points
- Advance assurance is not mandatory, but investors often expect it before committing funds.
- Keep consistency between your application, business plan and investor materials – discrepancies may cause delays.
- Avoid preferential share rights, as these continue to pose a significant risk of disqualification.
- Be aware of threshold and limit changes that apply in SEIS and EIS (see below).
- You can expect HMRC to review your submission and respond within ~4–8 weeks, depending on complexity.
🧾 Updated Thresholds & Important Changes
Since some earlier articles this has not been updated, here are important threshold changes you should be aware of.
- Under SEIS: The lifetime amount your company may raise under SEIS is now up to £250,000, following the change from 6 April 2023.
- Under EIS: For non-KIC companies, the gross assets limit remains at around £15 million pre-issue, with a lifetime maximum raise of about £12 million, though for KIC companies this is higher.
- The definition of “first commercial sale” and initial investing periods remain as 7 years (10 years for KICs) but be aware that guidance and thresholds evolve, so check current HMRC internal manuals before applying.
Summary
Applying for SEIS/EIS advance assurance online is straightforward when you’re well prepared. Gather your documents, ensure your forecasts align with your funding request, and explain clearly how the investment supports growth.
If you’re unsure at any stage, or if your company has subsidiaries, restructuring plans, or complex funding arrangements, it’s best to let a professional tax advisor handle your submission to avoid costly rejections.
