In this post, we’ll walk through why having structured SEIS and EIS templates is vital, what you get in the Oriel IPO pack, and how you can align your due diligence process with UK tax relief requirements. No fluff. No jargon. Just straightforward tools and tips so you can spend less time on paperwork and more time on what matters—building relationships and backing the next big thing.

Understanding SEIS and EIS: A Quick Primer

SEIS (Seed Enterprise Investment Scheme) and EIS (Enterprise Investment Scheme) are UK government initiatives designed to encourage early-stage investing by offering generous tax reliefs. They’re not complicated once you know the basics—but beginners can easily get lost in the eligibility criteria and compliance rules.

Key benefits:
– Income tax relief (up to 50% for SEIS, 30% for EIS).
– Capital gains tax exemptions on qualifying gains.
– Loss relief if the investment doesn’t work out.

SEIS targets very early companies (less than 2 years old, under £150,000 raised). EIS supports somewhat more developed ventures (up to £5 million per year). Accountants and investors often consult dense guidance manuals. Why reinvent the wheel? Structured templates ensure you tick every box and avoid nasty surprises.

Pro tip: If you’re guiding a client through SEIS, use our Learn about SEIS opportunities template for step-by-step simplicity.

Why Templates Are a Must for Due Diligence

Imagine you’re assessing three startups this week. Each has its own pitch deck, financial model, and set of documents. Without a template, you end up creating checklists from scratch every time. That’s inefficient and error-prone.

Templates give you:
– Consistency. You’ll apply the same rigorous criteria to every opportunity.
– Speed. Pre-formatted sections mean you only fill in the blanks.
– Confidence. No more second-guessing whether you covered HMRC compliance points.

Even seasoned investors appreciate a “cheat sheet” that highlights the tricky parts of SEIS/EIS compliance—like share capital rules or advance assurance processes. Templates combined with a one-page tax relief overview let you breeze through the paperwork.

  1. Gather company information (articles of association, share capital schedule).
  2. Fill in the HMRC advance assurance template.
  3. Update your financial model with relief-adjusted projections.
  4. Use the tax-relief cheat sheet to confirm claim windows.
  5. Draft investor communications with the presentation deck.

Four steps. One pack. And suddenly you have a robust workflow. No need to juggle five websites and a pile of PDFs.
