What Is HMRC Advance Assurance?
You’ve heard of SEIS and EIS. Great tax relief for investors. But they come with paperwork. That’s where HMRC advance assurance steps in.
- It’s non-statutory.
- It’s discretionary.
- It’s your pre-check with HMRC that your company ticks the boxes for SEIS or EIS.
Think of it as a weather forecast. You don’t have to wait for the storm to hit. You get a heads-up. That reassurance makes investors more comfortable writing hefty cheques.
This EIS advance assurance guide walks you through every step. No jargon. No fluff.
Why You Need This EIS Advance Assurance Guide
Imagine you’re pitching to an angel. They ask: “Have you got advance assurance?” You fumble. Confidence dips. The cheque shrinks.
With advance assurance:
- Investors see less risk.
- They don’t need to wait for confirmation.
- Deals close faster.
This EIS advance assurance guide ensures you breeze through the HMRC process. And yes, it applies equally to SEIS.
Step-by-Step: Your EIS Advance Assurance Guide
Here’s the nitty-gritty. Follow this EIS advance assurance guide like a recipe for cake. Miss one ingredient and your cake—er, application—might flop.
1. Check Your Eligibility
Before diving in, ask yourself:
- Is your company independent?
- Are you carrying on a qualifying trade?
- Do you meet the “new growth and development” condition?
- Is your business under seven years old (or ten for knowledge-intensive)?
Pro tip: If you’re borderline, gather technical analysis. HMRC hates speculative applications.
2. Gather Your Documents
HMRC wants detail. Provide:
- Amounts you intend to raise.
- Exact use of funds.
- Latest company and subsidiary accounts.
- Draft prospectus or investor deck.
- Business plan.
- Memorandum & Articles of Association (with changes).
- Register of members.
- Any subscription or side agreements.
- Details of prospective investors (unless listed on AIM or via a promoter).
- Evidence for de minimis aid (SEIS only).
Roughly 12–15 items. No surprises. Keep them organised in PDF.
3. Complete the Online Form
For SEIS and EIS, HMRC offers an online form. It’s straightforward:
- Tax reference and company details.
- Attach supporting documents.
- Provide technical analysis if needed.
If you’re applying for Social Investment Tax Relief, use a covering letter and email or post docs.
4. Submit and Track
Hit “Submit.” Now what?
- HMRC may come back with queries.
- They’ll opine on genuine applications only.
- They won’t engage if they think it’s testing the limits.
Expect a response in 4–6 weeks. Pin your hopes on no nasty surprises.
5. Respond Promptly
If HMRC asks for clarifications:
- Reply within 10 working days.
- Keep responses concise.
- Reference your original application.
Stalling costs time. And time kills deals.
