Advance Assurance: How It Can Help Your Business

If you’re an ecommerce seller, content creator, or early-stage entrepreneur looking to raise investment, Advance Assurance can be a powerful tool. It gives potential investors confidence and can make securing funding far easier.


What is Advance Assurance?


Advance Assurance is a formal confirmation from HMRC that your business qualifies for SEIS (Seed Enterprise Investment Scheme) or EIS (Enterprise Investment Scheme). These schemes provide tax reliefs for investors who buy shares in your company, helping you attract investment more easily.


Why it matters: investors are more likely to commit money if they know they’ll receive tax relief, and Advance Assurance provides that reassurance before they invest.


How Advance Assurance Benefits Your Business

  1. Builds investor confidence
    Investors are more willing to invest in your company if they know HMRC has confirmed it qualifies for SEIS or EIS. This can be the difference between securing funding or missing out.
  2. Speeds up fundraising
    Without Advance Assurance, investors may hesitate until after the investment is made. Getting assurance first can shorten fundraising cycles.
  3. Reduces risk of compliance issues
    HMRC’s confirmation ensures that your structure, share classes, and business activities align with SEIS/EIS rules, reducing potential complications later.


Ecommerce businesses

  • Example 1: A small Shopify store selling eco-friendly home products wants to raise £50,000 to expand its product line. By obtaining Advance Assurance, the founder reassures investors that their SEIS tax relief is secure, helping them reach their target faster.
  • Example 2: An Amazon seller planning to launch a new brand of health supplements can use Advance Assurance to show early investors that SEIS/EIS relief is confirmed, making it easier to secure investment for stock and marketing.


Content Creators

  • Example 1: A YouTuber selling branded merchandise wants to raise funds to expand into a full merchandise line with Shopify and Etsy. Advance Assurance can help attract investors by confirming eligibility for SEIS/EIS relief, making investment more appealing.
  • Example 2: A Twitch streamer looking to invest in a limited edition merch drop can reassure backers that they’ll benefit from tax relief, making fundraising faster and simpler.


How to Apply for Advance Assurance

  1. Check your eligibility
    Your company must be a UK-registered company carrying out a qualifying trade and not have raised over SEIS/EIS limits in the past.
  2. Prepare your business case
    Include details of your business activities, plans, and projected funding requirements.
  3. Submit to HMRC
    Once approved, you’ll receive a letter confirming your eligibility. This can be shared with potential investors.


Tip: Even if your investors are not yet ready, obtaining Advance Assurance early signals professionalism and preparation.
